Discovery in California Civil Litigation: A How-To Guide for Legal Professionals.

Discovery is the process by which parties in a civil lawsuit exchange information and evidence before trial. In California state courts, discovery is governed by Code of Civil Procedure (CCP) §§ 2016.010–2036.050 and includes tools such as depositions, interrogatories, requests for production of documents, requests for admission, subpoenas, and medical examinations. Unlike federal court, California has no automatic initial disclosures, meaning parties must affirmatively serve discovery requests to obtain information. Below is a comprehensive guide on how discovery works in California civil procedure, focusing on interrogatories, requests for production, and requests for admission, with an emphasis on how a defendant should analyze and respond to a plaintiff’s discovery requests. We also include practical tips on service, timing, objections, and sample response language, without making any unwarranted assumptions or inventions.

Overview of the Discovery Process in California

• Purpose of Discovery: The goal is to allow each party to gather relevant evidence, narrow the issues, and avoid surprises at trial. California follows a broad discovery scope – any non-privileged information “relevant to the subject matter… and reasonably calculated to lead to the discovery of admissible evidence” is discoverable. This includes not just evidence directly admissible at trial, but also information that could lead to discovery of such evidence. Discovery helps clarify what facts are in dispute and can facilitate settlement or streamline the trial.
• Timing: In an unlimited civil case (over $25,000 in controversy), the plaintiff may generally start propounding discovery 10 days after serving the summons and complaint (or even with the complaint, which extends the response time), and a defendant may begin discovery at any time after being served without leave of court. Discovery can continue until the “discovery cut-off,” which in California is 30 days before the initial trial date (with some exceptions for expert discovery). Written discovery must be served early enough so that responses are due before this cut-off (for instance, at least 65 days before trial to account for the 30-day response period plus time for mailing).
• Service of Discovery Requests: All discovery requests (and responses) are served on other parties, not filed with the court. Service is typically done by mail or electronic service (electronic service is allowed with consent or by court order, per CCP § 1010.6). The request must be served on the party’s attorney if they have one, or on the self-represented party directly. A proof of service (e.g., California Judicial Council form POS-030) should be completed by the server to document the date and method of service. Importantly, the original discovery request or response and the signed proof of service should be retained by the serving party – they are not filed with the court but may be needed as exhibits if a discovery motion arises.
• Response Deadlines: A party who is served with interrogatories, requests for production, or requests for admission generally has 30 days to serve responses (plus an extension of 5 days if the requests were served by mail within California, or 2 court days if served by email). These time limits are strict. If the due date falls on a weekend or holiday, the deadline typically rolls to the next court day. It’s common courtesy (though not guaranteed by law) for attorneys to stipulate to brief extensions if needed, but any extension should be confirmed in writing. Failure to respond within the deadline can have serious consequences, as discussed below.
• No “General Objection” Filings: In California state practice, discovery requests and responses are not filed with the court (except when submitted as exhibits for a motion). This means a responding party should serve their answers or objections on the propounding party and any other party entitled to copies, but should not file them in the court’s docket. The court only becomes involved if there is a dispute that results in a motion (e.g. a motion to compel).
• Sanctions for Non-Compliance: Discovery is largely self-executing, but the court can impose sanctions for misuse of discovery or failure to respond. If a party fails to respond at all to properly-served discovery, the requesting party can file a motion to compel initial responses (no meet-and-confer required in this situation) and the court will order responses and often require the non-responding party to pay monetary sanctions. In the case of requests for admission, an even harsher outcome is possible: if no response is served, the requesting party may move to have each matter deemed admitted by the court, effectively binding the non-responding party to those admissions. Additionally, late responses (served after the 30-day deadline without an agreed extension) result in waiver of all objections, including privilege (unless a court relieves the waiver on noticed motion for good cause) – a disastrous outcome for the responding party. Therefore, timely and proper responses are critical.
• Meet-and-Confer Requirement: If responses are served but a party finds them insufficient or improper, California requires the parties to “meet and confer” in good faith to attempt to resolve the issue before involving the court. Only after such efforts (typically an exchange of letters or a phone discussion outlining the deficiencies) can the aggrieved party file a motion to compel further responses. A motion to compel further answers or production must be noticed within 45 days of service of the deficient responses (plus mailing time) or the objections/answers are deemed accepted. On the other hand, if no response was served at all, a motion to compel can be filed at any time and will be granted virtually automatically, since no responses were provided. Always document your meet-and-confer efforts in writing, as you may need to show the court you attempted to resolve informally.

With this background in mind, let’s turn to the specific discovery devices – Interrogatories, Requests for Production, and Requests for Admission – and walk through how a defendant in California should analyze and respond to each when served by a plaintiff.

Analyzing Discovery Requests from the Opposing Party

When a defendant is served with discovery (be it interrogatories, production demands, or admission requests), a systematic approach to analyzing and preparing responses will ensure compliance and protect the defendant’s interests. Here is a step-by-step strategy:

1. Confirm What Was Served and Calendar the Deadlines: Carefully review the documents served by the plaintiff to identify each type of discovery request and the date of service. Common types include Form Interrogatories, Special Interrogatories, Requests for Production of Documents (RFPs), and Requests for Admission (RFAs). The package may include separate sets of each. Determine the due date for responses (30 days from service, or 35 days if by mail within California). Mark this on your calendar and account for any agreed extensions in writing. If multiple sets were served (e.g., “Interrogatories, Set One” and “Requests for Production, Set One”), each set’s responses are due on the same timeline unless otherwise agreed.
2. Assess the Numerical Limits (especially in Unlimited cases): California places limits on certain discovery requests. In an unlimited civil case, a party may serve up to 35 specially prepared interrogatories (not counting official Judicial Council Form Interrogatories) without a declaration of need, and up to 35 requests for admission (not counting those solely relating to the genuineness of documents) without leave of court. There is no statutory limit on RFPs in unlimited cases (practically, they should not be oppressively numerous). If the plaintiff’s requests exceed these limits and are not accompanied by the required declaration of necessity (CCP § 2030.050 for interrogatories, § 2033.050 for admissions), the defendant can object on that basis and is only obligated to respond to the first 35 of each type. (Note: In limited civil cases (amount in controversy $25,000 or less, or $35,000 for cases filed after Jan 1, 2024), there is a combined limit of 35 total discovery requests, including form interrogatories, special interrogatories, RFAs, and RFPs. However, this guide focuses on unlimited civil cases, which are more common for complex litigation.) Count the requests to see if an “exceeded number” objection is appropriate.
3. Read Each Request Carefully: Go through each interrogatory, document request, or admission request one by one. Parse the language – what exactly is being asked or demanded? Identify the key terms and any definitions provided in the instructions or preamble. If any request is vague, ambiguous, or unintelligible, note that for potential objection. For example, an interrogatory that asks multiple things at once (compound question) or an RFP that is so broad you cannot tell what documents are sought should raise a red flag. Pay attention to whether requests are compound (which is not allowed for interrogatories – only one question per interrogatory – and similarly, RFAs must not contain multiple facts in one request). Also, ensure you understand any references (e.g., “the ACCIDENT” or “SUBJECT PROPERTY”) – these should be defined in the discovery instructions. If they are not clear, that might be a point for meet-and-confer or objection (e.g., “vague and ambiguous as to time or scope”).
4. Evaluate Relevance and Scope: Consider how each request relates to the claims and defenses in the case. Under CCP § 2017.010, the scope of discovery is generally matters relevant to the subject matter involved in the pending action, and admissible or reasonably calculated to lead to admissible evidence. If a request seeks information that is clearly outside the scope of the case or not likely to lead to relevant evidence, note it. For instance, in a simple car accident case, a demand for all of defendant’s employment records for 10 years is probably overbroad and irrelevant, unless lost income is at issue. Such requests may warrant an objection for irrelevance or overbreadth. However, be mindful that relevance in discovery is interpreted broadly – if there is any legitimate line of inquiry that might make the information useful, the court may allow it. Clearly egregious requests (e.g., all financial records in an injury case with no punitive damages or economic claims) can be challenged.
5. Identify Privileged or Confidential Material: Determine if any request calls for information or documents that are privileged or protected. Privileges common in civil discovery include attorney-client communications, attorney work product, trade secrets, privacy rights, physician-patient, etc. For example, an interrogatory asking for “all communications with your attorney” is objectionable (attorney-client privilege), as would an RFP for “all internal corporate investigations conducted by defendant’s counsel” (work product). Mark those requests for a privilege objection. If documents are involved, you will likely need to prepare a privilege log describing any withheld documents and the basis of the privilege. Similarly, if a question seeks someone’s social security number or medical information not at issue, you might object on grounds of privacy. California’s Constitution recognizes a right to privacy, so you may need to balance that against the need for the information.
6. Check for Procedural Defects: Ensure the discovery requests themselves comply with California’s rules. For example, interrogatories must be numbered consecutively and cannot exceed 35 without a declaration; RFAs must be separately stated and not compound; RFPs should describe items with reasonable particularity (vague categories can be objected to) and specify a reasonable time, place, and manner of production (CCP § 2031.030). If the plaintiff served Form Interrogatories, verify they used the latest Judicial Council form (DISC-001) and only checked the boxes for applicable questions (sometimes parties inadvertently include irrelevant form questions, which you can object to as burdensome/oppressive if not tailored). If any requests are improperly formatted or served (e.g., not signed, or served before allowable time), those issues should be noted and possibly raised.
7. Plan Your Response Strategy: For each request, decide whether you will answer, object, or both. California law encourages responding parties to answer as much as they can even if part of a question is objectionable. Partial objections are allowed – you can object to the improper part of a question and answer the rest. Begin drafting preliminary answers and objections:
   • If a request is answerable, you’ll need to gather the responsive information or documents. Start collecting facts or documents from your client early, as it may take time.
   • If a request is objectionable, decide on the specific grounds of objection. Common objections include: irrelevant, not reasonably calculated to lead to admissible evidence, overbroad, unduly burdensome or oppressive, vague and ambiguous, compound (for interrogatories), calls for speculation, calls for a legal conclusion, privileged, violates privacy, or exceeds numerical limits. We’ll discuss these in detail in the context of each discovery type below.
   • Be specific in objections; boilerplate or generalized objections (e.g., simply stating “irrelevant and burdensome”) are disfavored. Tailor the objection to the request (“Request No. 12 is overbroad as to time because it seeks “all documents ever relating to X” without any time limitation, and is not limited to the subject matter of this litigation, making it unduly burdensome to respond”).
   • If an interrogatory or RFA is only partially objectionable (e.g., it has two clauses and one is proper, one is not), you should answer the unobjectionable portion. For RFPs, if some documents are privileged or beyond scope, state you will produce the rest and withhold those identified in a privilege log.
   • Consider whether any protective order is needed (rare at the responding stage unless the requests are extremely abusive or seek trade secrets/confidential info that you’d only produce under a confidentiality agreement).
8. Meet and Confer if Necessary (Optional at this Stage): If you encounter requests that are unclear or obviously improper, you might informally reach out to opposing counsel for clarification or relief before the response is due. While not required to meet-and-confer before serving initial responses, doing so can sometimes resolve issues (for example, plaintiff might agree to narrow a request or extend the deadline). Any agreements or clarifications should be confirmed in writing (e.g., an email confirming “Plaintiff agrees to withdraw RFP No. 8” or “parties stipulate to two-week extension for responses”). If no agreement is reached, you will proceed with formal responses including appropriate objections.
9. Prepare the Response Documents: Each type of discovery usually requires a separate response document (e.g., “Response to Interrogatories, Set One” and “Response to Request for Admissions, Set One”). Follow the format required by the California Rules:
   • Use the standard caption page (case title, court, parties, set number, etc.).
   • Generally, you do not retype each question before the answer in California practice (unlike some jurisdictions). Instead, you may reference them by number. For clarity, many attorneys do repeat the full text of each interrogatory or request before the response – it’s not required but can be convenient. If you do repeat the request, ensure you do so exactly as written.
   • Respond separately to each item, numbered identically to the request. Do not combine responses or answer a question that wasn’t asked.
   • For each response, state any objections first, then the answer (if any part is answered). If you object and refuse to answer in entirety, make sure the objection is well-founded and likely to be upheld, because providing no information can prompt a motion to compel.
   • End the document with the proper signature and verification (discussed more below).
10. Verify and Sign: In California, responses to interrogatories and requests for admission must be verified by the responding party – meaning the client (not the attorney) signs an oath at the end of the document affirming the truth of the responses. For requests for production, any factual statements (such as claims of inability to comply) also must be verified by the party. If the response to a production request consists solely of objections and no factual assertions, only the attorney’s signature is required (since there’s nothing for the client to verify). As the attorney, you will sign the responses as to form (and to certify objections are not for improper purpose under CCP § 2023.010 et seq.), but ensure your client timely reviews and signs the verification before serving. An unverified response (when verification is required) is tantamount to no response at all, which can lead to waiver of objections and sanctions.
11. Serve the Responses Properly: Arrange for service of the response documents on the plaintiff’s counsel (or self-represented plaintiff) and all other parties who appeared in the case. Service must be done by someone over 18 who is not a party to the case (typically, your office assistant or a process server). They should serve the original signed responses on the propounding party (plaintiff’s attorney) and copies on all other parties’ attorneys as a courtesy. Complete a Proof of Service form (POS-030 for mail) and have the server sign it. Keep the original proof of service and a copy of the served responses in your file. Do not file these with the court.
12. Retain and Follow Up: Keep organized files of what was asked and how you responded. Calendar the 45-day deadline from service of your responses in case the plaintiff challenges any objections with a motion to compel further responses. If you stated you would produce documents, follow through and produce them by the agreed date (often production is coordinated to occur simultaneously with the written responses, or shortly thereafter). If any new information emerges later (after your response), note that unlike federal court, California generally has no automatic duty to supplement discovery responses. However, strategically you might choose to voluntarily supplement to correct material inaccuracies or to include after-acquired information, to avoid surprises or sanctions later.

Having outlined the approach to analyzing discovery requests, we will now delve into each type of discovery – Interrogatories, Requests for Production, and Requests for Admissions – for more specific guidance and examples.

Responding to Interrogatories (CCP § 2030)

Interrogatories are written questions that one party sends to another, requiring written answers under oath. They are a staple of discovery for gathering facts, contentions, and positions of the opposing party in their own words. California recognizes two kinds of interrogatories: Form Interrogatories and Special Interrogatories.

• Form Interrogatories: These are pre-approved standardized questions published by the Judicial Council (Form DISC-001 for general civil cases). They cover common topics (e.g., background information, witness identities, damage computations) and do not count against the numerical limit of 35, up to a limit of 35 on the form itself. Form interrogatories are convenient and often used; the propounding party will typically attach a checked-off list of the specific form questions being asked. Despite being “form” questions, a responding party must still evaluate relevance – if a particular form interrogatory is not applicable, the responding party may object or answer “not applicable” (for example, questions about property damage in a case with none).
• Special Interrogatories: These are custom-written questions drafted by the opposing party, tailored to the specifics of the case. In an unlimited case, the plaintiff may propound up to 35 special interrogatories as a matter of right. Each question must be full and complete in itself (no subparts or compound questions are allowed in one interrogatory) – if an interrogatory is compound, the responding party can object to it as impermissibly compound. If the plaintiff needs more than 35 special interrogatories, they must serve a Declaration of Necessity (explaining why additional questions are required), or else obtain a court order. Without such a declaration, the defendant can refuse to answer any special interrogatories beyond the 35th, by objecting that the limit has been exceeded.

Key rules for interrogatory responses:

• Answer Each Question Fully or State Objections: The CCP requires that “each answer in an interrogatory response shall be as complete and straightforward as the information reasonably available to the responding party permits”. This means the defendant must provide all requested information that is known, after a reasonable inquiry. If you don’t know the answer to something, you cannot simply refuse to answer – you must state that you have made a reasonable investigation and the information you have is insufficient to respond. You are not allowed to avoid answering by saying “investigation continues” or “will supplement later” (these are improper in California; you answer with what you know as of now, and if truly you have no information, say so under oath after reasonable diligence). If an interrogatory is objectionable, you may object, but be specific and only object if there is a legitimate ground. Common objections include:
  • Compound Question: The interrogatory asks more than one independent question in a single request (violating CCP §2030.060). Example Objection: “Defendant objects that this interrogatory is impermissibly compound, as it asks for two distinct pieces of information (the identity of witnesses and their locations) in a single question.”
  • Vague or Ambiguous: You genuinely cannot discern what information is sought. Example: “Defendant objects that this interrogatory is vague and ambiguous as to the phrase ‘send statements’ – it is unclear what statements or time frame are being referenced.”
  • Overbroad / Burdensome: The scope of the interrogatory (time period or subject matter) is too wide, making it oppressive to answer. Example: “Objection: This interrogatory is overbroad and unduly burdensome insofar as it seeks ‘all facts supporting your defense’ without any limitation in time or subject, essentially asking Defendant to marshal all evidence in its possession.” (Courts often disfavor “identify all facts” interrogatories for this reason, though contention interrogatories are allowed – but they must be bounded in scope.)
  • Irrelevant / Not Likely to Lead to Admissible Evidence: The interrogatory seeks information unrelated to the case. Example: “Defendant objects that this interrogatory seeks information not relevant to the subject matter of this action and not reasonably calculated to lead to the discovery of admissible evidence, in that it requests detailed financial information despite no claim for lost income or punitive damages.”
  • Privileged: The question asks for content of communications with counsel or work product. Example: “Objection: This interrogatory calls for information protected by the attorney-client privilege and/or attorney work-product doctrine (it asks for Defendant’s ‘analysis and strategy’ regarding the case).”
  • Calls for Legal Conclusion or Expert Opinion: Pure legal questions are better left for the court, though contention interrogatories (applying law to fact) are permitted. You might object if it squarely asks a legal conclusion that’s improper. Example: “Objection: Calls for a legal conclusion – Defendant is not required to opine on the legal validity of Plaintiff’s claim through an interrogatory.”
  • Speculative or Hypothetical: “Objection: Calls for speculation – the interrogatory asks Defendant to guess what could have happened under different circumstances, which is not a proper inquiry.”
  • Asked and Answered / Duplicative: If the same question is asked twice (or was asked in a deposition already), you can note that to avoid redundant work.
  Always consider if an objection alone is sufficient or if you can provide an answer after stating an objection (“Object on X ground. Without waiving, answer…”). Many attorneys object on the record then answer anyway to avoid motions. If you completely refuse to answer, be confident the objection would be upheld by a court.
• Verification: As noted, each interrogatory answer set must end with a verification signed by the client under penalty of perjury attesting that the answers are true. Ensure the verification references the jurisdiction (e.g., “I declare under penalty of perjury under the laws of the State of California that the foregoing answers are true and correct”). An unverified answer (unless only objections are stated) is ineffective.
• Structure of Answers: You do not need to quote the question, but do number your responses to match each interrogatory. If an interrogatory has subparts (a, b, c) – which shouldn’t happen in a single interrogatory, but sometimes plaintiffs draft them that way – you can object that it’s compound, or you could respond to each subpart separately for clarity. Keep answers concise but complete. If the question asks for a list, provide a list or table. If it asks for an explanation, give a narrative. For anything that is burdensome to detail in full (like a list of hundreds of items), you might consider referring to records under CCP §2030.230, which allows a responding party under certain circumstances to specify writings from which the answer can be derived (akin to a “business records response”). But ensure the requirements are met (the interrogatory must be answerable by examining the party’s business records, and the burden of deriving the answer from them is substantially the same for both sides). This is not commonly used except in appropriate contexts (like voluminous data queries).

Practical Tip: If form interrogatories were served, the Judicial Council form itself (DISC-001) provides a pre-printed format for responses. Typically, one would just write “See attached response” and then produce a separate document on pleading paper with answers to each checked form interrogatory number. In those answers, you might simply answer straightforwardly or object as needed. For example, Form Interrogatory 2.1 (asking for insurance coverage) must be answered in personal injury cases – you would list the insurance info or state none. Form Interrogatory 17.1 (which asks for details on each denial of an RFA) is a common one that requires a particular format: it essentially links to RFAs, and you have to identify evidence and witnesses for each denial – this often takes significant work to answer properly.

Example – Special Interrogatory Response Sample

To illustrate, here’s a sample response to a hypothetical special interrogatory:

Interrogatory No. 5: Describe in detail each fact supporting your contention that the product was not defective.
Response to Interrogatory No. 5: Defendant objects to this interrogatory on the grounds that it is overbroad and unduly burdensome, in that it calls for “each fact” supporting an entire contention, effectively requiring Defendant to marshal all evidence. Defendant further objects on the ground that it seeks information not relevant to the extent it calls for facts unrelated to the specific defect alleged. Without waiving these objections, Defendant responds as follows: Defendant contends the product was not defective based on inter alia the results of quality control testing (Batch QA Reports dated June 1, 2023, and July 1, 2023, which revealed no anomalies), the product’s compliance with industry standards (UL certification #12345), and the absence of any other reported incidents among 10,000 units sold. Investigation is ongoing, and Defendant reserves the right to supplement this response if additional facts are discovered.

In this example, the response asserts objections but still provides a substantive answer to avoid appearing evasive. The answer includes specific facts known to date. The phrasing “investigation is ongoing…” is generally not encouraged (since technically there’s no duty to supplement in CA), but it’s often included as a caution. A cleaner approach might be to omit that and simply provide what you know.

Responding to Requests for Production of Documents (CCP § 2031)

Requests for Production (RFPs) (sometimes called demands for inspection or production) are written requests that another party produce and permit copying of documents, electronically stored information (ESI), or tangible things, or to permit entry onto land for inspection. In practice, RFPs are used to obtain copies of relevant documents and evidence in the other party’s possession or control.

Key features of RFPs in California:

• No Numerical Limit (Unlimited Cases): There is no set limit on the number of RFPs in an unlimited civil case (unlike interrogatories or RFAs) – a party may propound as many as are necessary, but must be mindful not to oppress the other side with unduly burdensome demands. Courts can issue protective orders or sanctions if RFPs are excessive or harassing.
• Format of Requests: Each RFP should describe with reasonable particularity the item or category of documents or things to be produced. Vague requests can and should be objected to. For example, “Produce any and all documents relating to Plaintiff” is too broad and not particular. A better request would be, e.g., “Produce all written contracts between Defendant and Plaintiff from 2019 to 2021.” Also, RFPs often specify the form in which ESI should be produced (e.g., PDF, native files, etc.). If they don’t and you have a preference or limitation (like an undue burden to produce certain format), you might negotiate that. Each request may also set forth a time and place for production or inspection – typically, the propounding party says something like “within 30 days at the office of [Plaintiff’s counsel] or by mail.” If a location or time is specified and it’s unreasonable, object or propose an alternative (most attorneys simply exchange documents by mail or secure file-share rather than an in-person inspection, unless it’s an inspection of a physical item or site).
• Response Time: Same 30-day rule (plus mailing days) applies. However, actual production of documents can occur slightly later by agreement, especially if the volume is large, as long as the written response is served in 30 days indicating what will be produced. It’s common to serve the written responses by the deadline and then produce the documents shortly after.
• Written Response Requirements: The response to each RFP must state either:
  1. Agreement to comply: that the responding party will comply and when the materials will be made available (by the deadline or a specified date). If you agree to produce everything requested, you might phrase it as: “Responding party will comply and produce all responsive documents in its possession, custody, or control. The documents will be made available by [date] at [method/location].” If the request asked for inspection of originals, you could say they will be available for inspection at a certain time/place. Often, though, parties agree to exchange copies instead of inspection.
  2. Inability to comply: that you cannot comply because the documents do not exist or never existed, or existed but no longer exist or are not in your possession. This response must be done in good faith – you are required to do a “diligent search and reasonable inquiry” to locate the documents before saying you have none. If you state inability because the item no longer exists or is not in your control, you must explain what happened to it or who has it, if known. For example: “After a diligent search and reasonable inquiry, Responding Party cannot comply with this request because the responsive documents were destroyed in a fire in 2021. No copies exist. Responding Party is unaware of any other custodian of these documents.”
  3. Objection: an objection to the request in whole or in part. If objecting only in part, you must comply with the rest of the request. If objecting in whole, you provide no documents. Common objections to RFPs include:
     • Overbroad/Burdensome: e.g., “any and all documents relating to X” with no time frame could be overly broad. Example: “Objection: This request is overbroad and unduly burdensome as phrased, insofar as it seeks ‘any and all records’ from an unspecified timeframe, which would encompass an unreasonably large volume of documents not narrowly tailored to the issues.”
     • Vague/Ambiguous: if you genuinely can’t tell what’s being asked for. Example: “Objection: The request is vague and ambiguous in referring to ‘the documents you showed me’ without identifying any specific documents or context.”
     • Irrelevant/Not likely to lead to admissible evidence: “Objection: The request seeks documents that are not relevant to any party’s claims or defenses and not reasonably calculated to lead to discovery of admissible evidence, specifically financial records of the defendant unrelated to the subject transaction.”
     • Privilege/Privacy: “Objection: The request seeks documents protected by attorney-client privilege and/or work product (such as internal legal memoranda). A privilege log will be provided identifying withheld documents.” or “Objection: The request seeks private third-party information (personnel files) and invades privacy rights. Responding party will only produce such documents subject to a suitable protective order.”
     • Over the limit (limited cases): In a limited case, if the combined 35 limit is exceeded, you might object: “Objection: This request, when taken with all other discovery requests, exceeds the permissible number of discovery requests in a limited civil case.” (This is not applicable in unlimited cases.)
• Production vs. Inspection: In practice, most RFP responses in civil cases result in the responding party producing copies of documents (often in PDF or paper form, or native files for things like Excel spreadsheets) rather than inviting the other side to come inspect originals. California law allows the responding party either to produce the materials or permit inspection. The requesting party can specify which they prefer, but usually the parties informally agree to exchange copies. If the request demands inspection of originals (common for things like journals, equipment, or other tangible items), coordinate a mutually agreeable time. The responding party can also choose to make copies available in lieu of inspection even if the request was for inspection – just communicate that in the response (“the documents will be copied and mailed to you at our expense” etc.). If copies are provided, it’s courteous to provide them to all parties (especially in multi-party cases) to avoid duplicate RFPs.
• Privilege Log: If you withhold any documents on the basis of privilege or privacy, you must serve a privilege log with enough information to identify the document and explain the privilege claim (date, author, recipient, general description, privilege claimed). The privilege log is usually not required the exact day of the response, but must be provided within a reasonable time. However, best practice is to include it with or shortly after the responses. If you fail to list a document on a privilege log, you risk waiving the privilege for that item.
• Verification: As noted earlier, if your response includes factual statements (like an inability to comply or a representation that all documents have been produced), it must be verified by the client. If your response is pure objections and no documents will be produced, only an attorney signature is needed (no client verification). Be careful – if you object and also state some facts (e.g., “and no such documents exist”), that’s a factual assertion which triggers verification. Many lawyers in practice choose to verify all responses anyway to avoid any doubt.
• Partial Compliance: If only part of a request is objectionable, you must produce the rest. For instance, if a request asks for documents from 2010 to present and you object to anything before 2015 as irrelevant, you should state that and agree to produce 2015-present. Don’t withhold the entire set if only a subset is problematic. State clearly what you are withholding. Under a relatively recent change (modeled after Federal Rule 34), it’s good practice to state whether any documents are being withheld on the basis of each objection. For example: “Responding party will produce documents responsive to this request for the period 2019-2021. Responding party objects to producing documents earlier than 2019 as irrelevant and burdensome; no documents dated prior to 2019 will be produced.” This informs the propounding party of the limitation.

After serving the written responses, the next step is to actually produce the documents (if any). The written response might say “will produce documents.” You should then either attach the documents (if few) or send them in a separate transmission. Typically, documents are bates-stamped (numbered) for reference. You might send them via secure download link or physical media. Always include a cover letter referencing the RFP set and listing what is produced (e.g., “Enclosed please find DEFENDANT’s production of documents Bates Nos. DEF001-DEF050 in response to Plaintiff’s Request for Production, Set One.”).

Keep a copy of exactly what you produced. If the other side later claims something was missing, you’ll want to know what you provided.

Example – Request for Production Response Sample

Below is a sample response to an RFP:

Request for Production No. 10: “Produce all documents that refer or relate to the design of the product model XYZ123.”
Response to Request No. 10: Objection. This request is overly broad and unduly burdensome, and it seeks information that is not relevant to the subject matter of this action. Specifically, the request is not limited to any time frame or aspect of the product’s design, and “refer or relate to” is vague and could encompass virtually every email or note ever created by Defendant’s engineering team. The request also seeks confidential commercial information (trade secrets) protected by Civil Code § 3426 et seq. Subject to and without waiving these objections, Responding Party will produce non-privileged, responsive design specification documents for the XYZ123 product that were in effect during the two years before the incident at issue. Design documents outside that period or relating to other models will not be produced as they are not relevant. Documents containing trade secrets will be produced pursuant to the protective order once entered by the Court (a proposed protective order has been sent to Plaintiff’s counsel). Responding Party will comply with this request as limited and will produce responsive documents (Bates Nos. DEF1000-DEF1050) within 10 days of these responses.

In this example, the response raised objections (overbroad, burdensome, relevance, confidentiality) and then narrowed the scope and agreed to produce a set of documents. It explicitly states what will not be produced (documents outside the two-year period, other models) and under what condition (after a protective order). This kind of clear response helps prevent misunderstandings and might avoid a motion to compel because the plaintiff sees what they will get and what is being withheld.

Responding to Requests for Admission (CCP § 2033)

Requests for Admission (RFAs) ask a party to admit or deny specific statements of fact, opinion, or the application of law to fact, as well as the genuineness of documents. The primary purpose of RFAs is to narrow the issues by eliminating those facts which are not in dispute. If a fact can be admitted by both sides, it need not be proven at trial. RFAs are a powerful tool – an admitted matter is conclusively established in the case (unless the court permits withdrawal or amendment of the admission for good cause).

Key points about RFAs:

• Numerical Limit: In unlimited cases, a party may serve 35 RFAs (excluding RFAs that only ask to authenticate documents) as of right. Any additional RFAs require a declaration of necessity (similar to extra interrogatories). Requests solely about the genuineness of documents are not counted toward the 35 limit (so you can ask to authenticate an unlimited number of documents, theoretically). In practice, lawyers sometimes send separate sets: one set of RFAs for facts (capped at 35) and another set for document authenticity (often enumerated separately). In limited cases, remember the combined limit of 35 total discovery requests applies.
• Format: Each RFA should be a concise statement that can be answered “Admit” or “Deny.” Compound or multipart admissions are not allowed. For example, an RFA should not say “Admit that on June 1 you signed the contract and it was raining” – that’s two facts (signing & weather) in one; it should be split into two RFAs. If you get a compound RFA, you can object that it violates CCP §2033.060 (no compound RFAs). Also, RFAs should not ask a party to admit a legal conclusion that is beyond the scope of the case (though they can ask admissions on legal conclusions “relating to facts of the case” per CCP §2033.010).
• Responding Substantively: For each RFA, the responding party must either:
  • Admit the matter, deny the matter, or qualify/partially deny/admit, or
  • State an objection (or a combination of objection and answer).
  California law (CCP § 2033.220) requires that responses be as complete and straightforward as possible and specifically admit or deny the matter, or explain in detail why you cannot. You cannot give evasive answers like “I don’t understand” (unless you genuinely don’t, in which case object for vagueness). Nor can you object on the ground that the matter is “in dispute” or that you “lack knowledge” without further explanation – the statute forces you to make a reasonable inquiry and if after that you still cannot admit or deny, you must say so in your response, detailing that you made a reasonable inquiry and the information known is insufficient to admit or deny. So, effectively you have four options for each RFA:
  1. Admit – If the statement is true, or mostly true. If it’s completely true, a simple “Admit” is fine.
  2. Deny – If the statement is false or you cannot fully admit it. If any part of a statement is false, you should deny (or at least deny the false part).
  3. Qualified Admission/Denial – If the RFA is partly true and partly false, admit the true parts and deny the rest. For example: “Admit in part and deny in part. Defendant admits that he was present at the meeting on June 1, 2020, but denies that he agreed to the terms as stated in this request.” This ensures you’re not trapped into over-admitting.
  4. Inability to Admit or Deny (Lack Sufficient Information) – If after diligent inquiry you genuinely cannot confirm or deny, you must say so and detail why. Example: “After reasonable inquiry, Responding Party is unable to admit or deny this request. The information known or readily obtainable is insufficient to enable an admission or denial.” This is often used when the matter depends on evidence outside your knowledge. But be cautious: if it’s something you should know or can find out, the court may expect an admission or denial. An unjustified “lack of information” response can lead to a motion to compel further response or even an order deeming the matter admitted if the court thinks you didn’t try hard enough.
• Objections to RFAs: There are fewer common objections to RFAs because RFAs, by nature, should be simple and relevant facts. However, you can object if:
  • The request is ambiguous or vague – e.g., it uses a term that is undefined or unclear. Then you might clarify in your response: “Objection, vague as to ‘substantially complied’; Responding Party interprets ‘substantially complied’ to mean X and on that basis denies.”
  • It calls for a legal conclusion unrelated to facts – pure abstract law is objectionable. But asking to admit something like “the contract was void due to fraud” might be seen as applying law to fact (which is allowed), albeit contention-laden. The court can allow those, or may defer them to later in discovery if they are contention RFAs.
  • It’s compound (violates the one-admission-per request rule) – object and do not admit or deny until it’s properly phrased.
  • Exceeds the numerical limit (more than 35 without declaration) – you could object to RFAs 36 and above on that ground, stating you will treat them as stricken absent a declaration.
  • Privilege is rarely an issue with RFAs because an RFA is asking to admit a fact, not asking for a document or communication. But conceivably an RFA could be worded to indirectly seek privileged info, though that’d be unusual.
• Consequences of Admissions: If you admit something, it is deemed established and you typically won’t be allowed to contradict it later. Only by a motion (showing mistake, etc.) can an admission be withdrawn. Therefore, be careful and only admit what you are fully comfortable is true. If part is true, qualify your admission. If you deny an RFA and the other side later proves that fact at trial, they can motion after trial for you to pay their costs of proof (attorney’s fees, expenses) under CCP § 2033.420 – basically a penalty for unreasonably denying something that should have been admitted. This rule is designed to encourage truthful admissions. For example, if the plaintiff asks you to admit your car was at location X on a certain date and you deny it but it was easily provable and they then prove it, you might have to pay their costs for that proof. On the other hand, if you had a reasonable ground to believe you might prevail on that issue, denial is not penalized. The standard is whether at the time of denial you had reasonable ground to believe you’d prevail on the matter, or the admission was of no substantial importance.
• Verification: Like interrogatories, RFA responses must be verified by the party (unless only objections are stated). Ensure your client signs the verification.
• If No Response Served: As mentioned, failing to respond to RFAs at all by the deadline is disastrous – the requesting party can move for an order that deems each request admitted. The court will grant that unless you served late responses before the hearing AND you pay their motion costs (and even then, the statute says if no timely response, the court shall deem admitted absent exceptional circumstances). This can effectively end a case (imagine all liability facts deemed true). Therefore, always prioritize RFA responses.

Answering strategy: If a fact is true, it’s often best to admit it and move on – save your fights for real disputes. If a fact is mostly true but not entirely, clarify the nuances in your answer. Don’t be evasive: courts can see when a denial is in bad faith. It’s acceptable to admit with explanation (though strictly speaking “admit” or “deny” is all that’s needed, you can add clarification if necessary to avoid misinterpretation).

Requests for Admission often work in tandem with other discovery. A common pattern is: RFA asks “Admit X is true.” If you deny, the propounding party’s next move is to use Form Interrogatory 17.1, which asks you to state all facts, witnesses, and documents supporting your denial of each RFA. So if you deny an RFA, be prepared to back it up with evidence or an explanation, because you’ll likely have to in an interrogatory answer. This is why blanket denials can backfire – you’ll have to explain them.

Example – Request for Admission Response Sample

Request for Admission No. 3: “Admit that Defendant ACME Corp. did not provide any written warning about the product’s risk of overheating.”
Response to Request No. 3: Responding Party objects that this request is vague as to time frame (it does not specify during what period or in what context a warning would be provided). Subject to that objection, Responding Party answers: Deny. Defendant ACME Corp. affirmatively states that it provided a written warning in the product manual regarding the risk of overheating (see ACME Product Manual, p. 10, warning: “Caution – risk of overheating if product is left in direct sunlight.”). Accordingly, it is false that no written warning was provided.

In this response, the defendant denied the RFA (since they did provide a warning) and even volunteered the reference to the warning (to demonstrate why the denial is justified). The objection about vagueness gives some cover in case the manual warning isn’t what plaintiff had in mind, but the answer then clarifies. The answer could have simply been “Deny” – which legally is sufficient. The additional explanation isn’t strictly required in an RFA response, but adding it can sometimes dissuade the opponent from pursuing a motion or at least show good faith (and if this were followed by Form Interrogatory 17.1, the defendant has essentially pre-answered it by providing the fact and document supporting the denial).

Additional Tips and Important Considerations

1. Serving Discovery and Responses: Always comply with the formalities of service. Use a proper proof of service form and have a non-party serve the documents. For efficiency, many attorneys in California agree to email service for discovery (especially since 2020, e-service has become common or even mandatory in some courts). If you serve by email and there’s no prior agreement or court order, make sure to get confirmation that the other side will accept email service (and note that email service adds 2 court days to the response time instead of 5 calendar days for mail). Keep evidence of service (e.g., sent email with timestamp or mail certificate of mailing).

2. The “Duty to Supplement”: In California state court, unlike federal court, there is generally no automatic duty to update your discovery responses if they were complete and accurate when made (except in specific situations, like an expert’s information under CCP §2034.610). However, if you learn your prior response is materially incorrect or incomplete, you should correct it, either by an amended response or informally, to avoid problems at trial or sanctions (a court can preclude use of evidence withheld or issue sanctions for misleading responses). Moreover, opposing counsel can propound a supplemental interrogatory or RFP just before trial (CCP § 2030.070, § 2031.050) specifically asking if there are updates. So it’s wise to update responses with significant new info.

3. Meet and Confer on Deficiencies: If you, as a defendant, served responses with objections and limited answers, be prepared for plaintiff’s counsel to possibly send a meet-and-confer letter if they think your responses are inadequate. This letter will explain why they believe certain answers or objections are deficient and ask you to supplement or change them. Take these seriously – the court expects a meaningful exchange. Evaluate their points: if an objection was flimsy, you might decide to withdraw it and provide the info to avoid a motion. If you stand by an objection, articulate your reasoning in a reply letter. The meet-and-confer process can result in compromise (maybe providing some additional info or a narrower set of documents). This process must happen before they file a motion to compel further responses. Document any agreements reached (e.g., if you agree to supplement an answer, do so in writing).

4. Motions to Compel: There are two types – motion to compel further responses (when responses were served but are insufficient) and motion to compel initial responses (when no responses were served). If you provided responses on time, the other side can file a motion to compel further within 45 days of service of the responses, after meet and confer. If you missed the deadline or served nothing, they can immediately move to compel initial responses and/or deem RFAs admitted. If a motion to compel further is filed, the court will look at the specific RFPs/rogs/RFAs in question, your objections, and answers, and decide if more info should be given. If your objections were not well-founded or answers were evasive, the court can order further responses without objections and impose monetary sanctions (typically ordering the losing side to pay the other’s attorney fees for the motion). To avoid this, only assert objections you would be prepared to defend before a judge.

5. Use of Discovery Responses in Litigation: Remember that interrogatory answers and RFA responses are binding in a sense – they can be used as evidence. An interrogatory answer can be read into evidence at trial (as an admission by a party opponent). An admitted RFA is conclusively established. Even a denied RFA can come into play – if you deny something and it’s proven, the cost-of-proof sanction looms. So treat drafting responses as drafting a statement under oath that could be read by the judge or jury. Don’t include unnecessary commentary or snark. Be professional and factual. On the flip side, as you gather plaintiff’s discovery responses, use their admissions to narrow issues or for summary judgment if they admitted key points.

6. Objecting to Format or Timing: If plaintiff’s discovery had procedural errors (served too early, more than 35 without declaration, not signed, etc.), you have options: you can either object outright and refuse to respond on those grounds, or point out the issue and answer anyway subject to reserving rights. Often, minor defects (like an unsigned demand) are waived by simply proceeding; major defects (like excess numbers) you’d object to. Also, if discovery was served before the case is “at issue” (e.g., plaintiff served the same day as the complaint by mail – CCP §2030.020 extends your time in that scenario by 20 days), make sure to calculate your due date correctly. If plaintiff served with the complaint, a defendant actually gets 30 + 30 = 60 days to respond to that discovery (30 days after service of summons or appearance, whichever first, plus the normal 30) per CCP §2030.020(c) and §2033.020(c) for example. Don’t accidentally rush or conversely don’t miss an extended deadline.

7. Serving Discovery as a Defendant: While this article focuses on responding to plaintiff’s discovery, remember that a defendant can and should serve their own discovery on plaintiff to gather information to defend the case. The strategies above similarly apply in reverse when you craft discovery requests (make them clear, within limits, relevant). Also, if plaintiff’s responses are weak, you have the same ability to meet and confer and move to compel.

8. Use of Templates and References: California Courts and local law libraries provide templates and exemplars for discovery responses. For instance, the Sacramento County Public Law Library has templates for responding to interrogatories, RFAs, and RFPs. These can provide a helpful starting format (proper caption, introductory wording, verification format, etc.). For example, a template response to RFP will show language like: “Responding Party hereby responds to the Request for Production of Documents (Set One) as follows…” and how to structure objections and statements of compliance. Using such a template ensures you include all required components (like the verification). That said, always tailor the substance to your case; never just copy boilerplate without thought.

9. Professionalism and Specificity: The trend in California (and most jurisdictions) is moving away from boilerplate objections. Courts expect attorneys, especially legal professionals, to cooperate in discovery and only fight over genuine issues. Being overly obstructionist (objecting to every single request with stock phrases) can damage your credibility and invite harsher court scrutiny. It’s often more effective to answer honestly where you can, object where you must, and discuss with opposing counsel pragmatically. This doesn’t mean waive important objections – it means pick your battles and always have a reason for each objection grounded in law or fact. If something truly is burdensome, be prepared to submit a declaration if it goes to motion, explaining the burden. If something is privileged, have that privilege log ready.

10. Review and Quality Control: Before sending out responses, double-check:

• Did you answer each and every number? It’s surprisingly easy to skip a number inadvertently. A missing response is treated like no response for that item.
• Are your objections complete and specific? Vague objections might waive the objection.
• Is your verification signed and dated by the right person? (e.g., an officer of a corporate defendant or the individual defendant).
• Have you included the case caption, set number, identity of responding and propounding party properly? (This should be on the first page and often right before the responses begin, e.g., “Response of Defendant XYZ, Inc. to Plaintiff’s Request for Production of Documents, Set One.”)
• If you referenced producing documents or providing a privilege log, is it attached or will it follow? Calendaring any follow-up production if not done simultaneously is important.

By following these guidelines, a defendant in California can confidently navigate the discovery process, responding to interrogatories, document requests, and admissions in a way that protects their rights while complying with legal obligations. Properly analyzing and answering the plaintiff’s discovery requests will put the defense in a strong position to avoid pitfalls like waiving objections or suffering sanctions, and it sets the stage for the defendant to use the discovery process affirmatively to prepare for a successful outcome in the case.
