Overview

Requests for admission can lock in key facts or, if ignored, result in deemed admissions that devastate the opposing side's case.

Key takeaway
Requests for admission ask the other party to admit or deny specific facts or document genuineness. If unanswered within 30 days, the matters are deemed admitted. CCP 2033.420 imposes cost-of-proof sanctions when a party unreasonably denies a fact that is later proved at trial.

CCP 2033: Statutory Framework

RFAs are governed by CCP sections 2033.010 through 2033.420. The statute authorizes requests to admit the truth of specified matters of fact, the application of law to fact, or the genuineness of specified documents.

The 35-RFA Limit

Each party may serve up to 35 requests for admission on any other party in a single set without a declaration of necessity. CCP 2033.030. To exceed 35:

  • Attach a declaration of necessity under CCP 2033.050
  • State that the additional RFAs are warranted by the complexity of the case or the number of issues
  • The declaration must be specific -- boilerplate justifications are insufficient
Counting Subparts
Unlike interrogatories, the counting rules for RFAs are less commonly litigated. However, a single RFA that contains multiple discrete requests for admission should be counted as multiple RFAs. Draft each RFA to address a single, discrete fact or document.

Strategic Allocation of the 35 Limit

In a standard PI case, allocate your 35 RFAs strategically:

Deemed Admissions: The Nuclear Option

How Deemed Admissions Work

Under CCP 2033.280, if a party fails to serve timely responses to RFAs, the matters are deemed admitted. This occurs automatically by operation of law -- no court order is required. The consequences are severe:

  • Every matter in the RFA set is treated as conclusively established for all purposes in the action
  • The requesting party may move for an order confirming the deemed admissions
  • Deemed admissions can establish liability, causation, and damages -- potentially ending the case

See the interactive flowchart on this page.

Calendar RFA Response Dates
Deemed admissions are one of the most common malpractice traps in civil litigation. Defense counsel who fails to calendar the response deadline can find their client's entire case deemed admitted. As plaintiff's counsel, serve RFAs early and track response dates meticulously. If responses are not received timely, move immediately for an order deeming matters admitted and for monetary sanctions.

Motion to Deem Matters Admitted

Under CCP 2033.280(b), when a party fails to respond to RFAs:

  • The requesting party may move for an order deeming the matters admitted
  • No meet-and-confer is required before filing
  • The court shall make the order unless the responding party serves substantially compliant responses before the hearing
  • The court shall impose monetary sanctions on the party or attorney who failed to respond
Practice Tip -- Timing of Motion to Deem Admitted: File your motion to deem admitted promptly after the response deadline passes. Do not wait weeks hoping for a late response. The longer you wait, the more likely the responding party is to serve late responses and argue that the motion is moot. If the responding party serves responses before the hearing, you are still entitled to monetary sanctions, but you lose the deemed admissions.

Motion to Withdraw or Amend Admissions

CCP 2033.300

A party may move to withdraw or amend admissions on a showing that:

  1. Mistake, inadvertence, or excusable neglect caused the admission, AND
  2. The party requesting admission will not be substantially prejudiced by the withdrawal

The Two-Part Test

Courts apply both prongs strictly:

Prong 1 -- Mistake/Excusable Neglect:
  • Calendaring errors by attorney or staff
  • Miscommunication about deadline responsibility
  • Medical emergency or other extraordinary circumstances
  • Simple negligence is generally sufficient if the delay is brief
Prong 2 -- No Substantial Prejudice:
  • The requesting party has not changed position in reliance on the admissions
  • The case is not on the eve of trial with no time for further discovery
  • The requesting party can still conduct additional discovery on the admitted matters
Wilcox v. Birtwhistle (1999) 21 Cal.4th 973
The California Supreme Court held that the trial court has broad discretion in ruling on motions to withdraw admissions. The court emphasized that the policy favoring resolution of cases on their merits generally supports granting motions to withdraw, provided there is no substantial prejudice to the opposing party.
Key Takeaway: While courts generally favor allowing withdrawal of deemed admissions, do not count on it. Serve RFAs early so that if you obtain deemed admissions, you have maximum leverage. The threat of deemed admissions often produces prompt responses and a more cooperative opposing party going forward.

Tactical Use of RFAs in PI Cases

Establishing Liability

Draft RFAs that target the elements of your cause of action:

Negligence (Motor Vehicle):
  1. Admit that YOU owed a duty of care to Plaintiff when operating YOUR vehicle on [date].
  2. Admit that YOU were operating YOUR vehicle at a speed greater than was safe for conditions at the time of the INCIDENT.
  3. Admit that YOUR vehicle made contact with Plaintiff's vehicle during the INCIDENT.
  4. Admit that YOU failed to maintain a safe following distance from Plaintiff's vehicle immediately prior to the INCIDENT.
  5. Admit that YOUR conduct was a substantial factor in causing the INCIDENT.
Premises Liability:
  1. Admit that YOU owned the SUBJECT PROPERTY on the date of the INCIDENT.
  2. Admit that a dangerous condition existed on the SUBJECT PROPERTY at the time of the INCIDENT.
  3. Admit that YOU had actual knowledge of the dangerous condition on the SUBJECT PROPERTY prior to the INCIDENT.
  4. Admit that YOU failed to warn invitees of the dangerous condition on the SUBJECT PROPERTY.

Establishing Damages

RFAs on damages narrow the issues and set up cost-of-proof sanctions:

  1. Admit that Plaintiff incurred medical expenses in the amount of $[amount] as a result of the INCIDENT.
  2. Admit that the medical treatment Plaintiff received from [provider] was reasonable and necessary.
  3. Admit that Plaintiff's medical treatment from [provider] was causally related to the INCIDENT.
  4. Admit that Plaintiff lost earnings in the amount of $[amount] as a result of the INCIDENT.
  5. Admit that DOCUMENT [medical bill] is a true and correct copy of the bill for medical services rendered to Plaintiff by [provider].

Authenticating Documents

RFAs are the most efficient way to authenticate documents for trial:

  1. Admit that DOCUMENT [Exhibit A] is a genuine copy of the police report for the INCIDENT.
  2. Admit that DOCUMENT [Exhibit B] is a genuine copy of the photograph taken at the scene of the INCIDENT.
  3. Admit that DOCUMENT [Exhibit C] is a genuine copy of YOUR vehicle's maintenance records.
  4. Admit that DOCUMENT [Exhibit D] is a genuine copy of YOUR insurance policy in effect on the date of the INCIDENT.
Practice Tip -- The RFA/Form Interrogatory 15.1 Combination: The most powerful discovery combination in California practice is serving RFAs together with Form Interrogatory 15.1. When the defendant denies an RFA, FI 15.1 requires them to state all facts, identify all witnesses, and identify all documents supporting the denial. This forces the defendant to reveal their entire defense on each denied fact. If they cannot identify supporting facts, the denial is exposed as unreasonable, setting up cost-of-proof sanctions.

Cost of Proof Sanctions: CCP 2033.420

The Statute

CCP 2033.420 is one of the most powerful sanction provisions in the Discovery Act. If a party denies an RFA, and the requesting party later proves the truth of the matter at trial, the court shall order the denying party to pay the requesting party's reasonable expenses incurred in proving that matter, including attorney's fees, unless:

  1. The denial was of reasonable merit at the time
  2. The admission sought was of no substantial importance
  3. The party had reasonable ground to believe they would prevail on the matter
  4. Other good reason existed for the denial

Setting Up Cost-of-Proof Sanctions

To maximize your ability to recover cost-of-proof sanctions:

  • [ ] Draft clear, unambiguous RFAs addressing specific, provable facts
  • [ ] Serve RFAs early so the defendant has full opportunity to investigate
  • [ ] Track every denial and the evidence that ultimately proves each denied fact
  • [ ] Maintain detailed billing records for time spent proving denied matters
  • [ ] File a motion for CCP 2033.420 sanctions after trial or summary judgment

Calculating Sanctions

Cost-of-proof sanctions include:

  • Attorney's fees for proving the denied matter at trial
  • Expert witness fees incurred to prove the denied matter
  • Court reporter and deposition costs related to proving the denied matter
  • Other reasonable expenses directly attributable to proving the matter
Track Your Time Separately
From the moment you receive RFA denials, begin tracking time specifically attributable to proving the denied facts. This includes deposition time, expert consultation, document preparation, and trial time. Detailed contemporaneous records are essential for a successful cost-of-proof motion.

Case Law on Cost-of-Proof Sanctions

Key decisions interpreting CCP 2033.420:

  • Brooks v. American Broadcasting Co. (1986) 179 Cal.App.3d 500: Cost-of-proof sanctions are mandatory unless the denying party establishes one of the statutory exceptions. The burden is on the denying party.
  • Garcia v. Hyster Co. (1994) 28 Cal.App.4th 724: Sanctions may be awarded even if the denying party had some basis for the denial, if the basis was not reasonable.
  • Stull v. Sparrow (2001) 92 Cal.App.4th 860: The party seeking sanctions must prove the truth of the matters denied and the reasonable expenses incurred.

Responding to Defense RFAs

Response Options

For each RFA, the responding party must choose one of the following responses:

ResponseWhen AppropriateRisk
AdmitThe matter is true and cannot be reasonably disputedConclusive admission -- cannot be contradicted at trial
DenyThe matter is not true after reasonable investigationCost-of-proof sanctions if the matter is later proved true
Deny in partPart of the RFA is true and part is notMust specify which parts are admitted and denied
Lack of informationCannot admit or deny after reasonable investigationMust state that reasonable inquiry has been made
ObjectThe RFA is improper (privilege, relevance, etc.)Must be made with specificity; boilerplate objections are insufficient

Common Defense RFAs and How to Respond

RFA: Admit that you were not wearing a seatbelt at the time of the INCIDENT.
  • If true: Admit. Do not deny provable facts -- it destroys credibility.
  • If uncertain: State that after reasonable investigation, sufficient information is not presently available.
RFA: Admit that you had consumed alcohol within 4 hours of the INCIDENT.
  • If false: Deny with confidence.
  • If true: Admit the fact; context can be provided in other discovery.
RFA: Admit that you had a preexisting injury to your [body part] prior to the INCIDENT.
  • Important: Distinguish between "injury" and "complaint." Admit what is documented in medical records. Qualify if needed.
RFA: Admit that you posted photographs on social media showing you engaged in physical activity after the INCIDENT.
  • Be very careful: Social media is discoverable. If posts exist, admit and explain in other discovery.
Never Deny Provable Facts
Denying facts that are easily proved true is one of the most damaging credibility mistakes a party can make. It exposes your client to cost-of-proof sanctions and, more importantly, destroys their credibility with the jury. When a fact is true, admit it. Fight the legal significance of the fact, not the fact itself.
Key Takeaway: RFAs are a strategic weapon, not a paperwork exercise. Thoughtful RFAs establish undisputed facts, authenticate documents, and create cost-of-proof exposure. Every RFA should serve a specific litigation purpose -- either narrowing the issues for trial or creating a sanctions trap for unreasonable denials. Combined with Form Interrogatory 15.1, RFAs provide a comprehensive factual framework that drives case evaluation and settlement.

Genuineness of Documents

CCP 2033.010(b)

RFAs may request that a party admit the genuineness of any relevant document. A document admitted as genuine is authenticated for all purposes in the action -- eliminating the need for foundation testimony at trial.

Procedure

  1. Attach a copy of the document to the RFA
  2. Request admission that the document is genuine
  3. If admitted, the document is self-authenticating at trial
  4. If denied, you must authenticate the document through testimony -- and may seek cost-of-proof sanctions if the document is ultimately proven genuine

Documents to Authenticate via RFA

  • [ ] Police/accident reports
  • [ ] Medical records and billing statements
  • [ ] Photographs and video of the scene
  • [ ] Insurance policies and communications
  • [ ] Maintenance and inspection records
  • [ ] Employment records and pay stubs
  • [ ] Business records of the defendant
  • [ ] Expert reports
  • [ ] Correspondence between the parties

Common Questions

What is a request for admission?

A request for admission asks the other party to admit or deny specific facts or the genuineness of documents. If admitted, the fact is conclusively established for the case. If the responding party fails to respond within 30 days, the matters are deemed admitted, which can be devastating.

What happens if the other side does not respond?

If the other side fails to respond to requests for admission within 30 days, all of the requested facts are automatically deemed admitted. This means those facts are treated as true for the rest of the case, including at trial. The party can seek to withdraw deemed admissions, but the court has discretion to deny the request.

What are cost-of-proof sanctions?

Under CCP 2033.420, if a party denies a request for admission and the requesting party later proves that fact at trial, the denying party must pay the reasonable expenses of proving the fact, including attorney fees. This creates a financial penalty for unreasonable denials and encourages honest responses.

How are RFAs used strategically?

Requests for admission can be used to establish basic facts that narrow the issues for trial, authenticate documents so they can be admitted without a live witness, set up cost-of-proof sanctions for unreasonable denials, and create admissions that can be used in summary judgment motions or at trial.
