How to Respond to a Request for Admissions: Deadlines and Answers

To respond to a request for admissions, you must serve written answers on the requesting party within 30 days, addressing each numbered item separately with an admission, a denial, a partial admission, a statement that you lack sufficient information after reasonable inquiry, or an objection. Miss that deadline and every request is automatically treated as admitted. Answer carelessly and you may end up paying the other side’s costs of proving the facts you denied.¹

The 30-Day Clock

Rule 36(a)(3) gives you 30 days from the date of service to deliver your written responses. The parties can shorten or extend that window by agreement under Rule 29, and the court can order a different period, but absent one of those, the default clock starts the moment you are served.¹ State rules generally fall in the 30 to 45 day range, so check your jurisdiction if you are not in federal court.

The penalty for missing the deadline is automatic. Every unanswered request is deemed admitted, and deemed admissions are conclusively established for the rest of the case. No grace period, no warning from the court. You can move to withdraw deemed admissions under Rule 36(b), but the court applies a two-part test that you have to satisfy: withdrawal must promote resolution on the merits, and it must not prejudice the other side.¹ That is a much harder place to argue from than simply answering on time. If you need more time, ask early. A stipulated extension under Rule 29 is routine; put it in writing.

The Four Ways to Answer a Request

Every numbered request calls for one of four substantive responses. Each response must be separately stated, corresponding to the numbering of the requests. You cannot bundle answers together.¹

Admit

Admitting a request conclusively establishes that fact for the pending case. Neither side needs to prove it, and the jury will be told it is true. An admission under Rule 36 applies only to the pending action and cannot be used against you in any other lawsuit or proceeding.¹ Admit facts that are genuinely undisputed. Fighting over things that are obviously true wastes resources and, as discussed below, can trigger a fee award.

Deny

A denial must fairly respond to the substance of the matter. Evasive or vague denials do not count; if the court finds a denial inadequate, it can treat the matter as admitted or order an amended answer.¹ Be direct. If a request says “Admit that defendant was driving the vehicle on January 5, 2025,” a denial should flatly deny that fact, not hedge with qualifications that muddy the water.

Admit in Part, Deny in Part

When part of a request is true and part is not, Rule 36 requires you to specify what you admit and what you deny, and to qualify the rest as needed. If a request asks you to admit that a contract was signed on a particular date and included a specific term, you might admit the signing date but deny the characterization of the term. Spell out precisely which portion you are admitting so there is no ambiguity about what remains in dispute.¹

Lack of Sufficient Information

If you genuinely do not know whether a matter is true, you can state that you have made a reasonable inquiry and that the information you know or can readily obtain is insufficient to admit or deny. This is not a shortcut. The rule requires an actual investigation before you claim ignorance: look through your records, talk to the relevant people, and make a real effort. A bare “insufficient information” answer that does not reflect a reasonable inquiry can be treated as an admission.¹

When to Object Instead

Some requests are improper, and the correct response is an objection. Where possible, still answer any non-objectionable portion of the request rather than stonewalling the entire item. Common grounds include:

Vague or ambiguous language that makes it impossible to know what you are being asked to admit. Identify the ambiguity and explain why a definitive answer cannot be given.
Compound requests that bundle multiple distinct facts into a single numbered item. Object and ask that the request be broken apart.
Privileged information, including attorney-client and work product. When you withhold on privilege grounds, Rule 26(b)(5) requires you to describe the nature of what is withheld in enough detail for the other side to assess the claim without revealing the privileged content itself.²
Irrelevant or disproportionate requests. Discovery must be proportional to the needs of the case. For volume that crosses into harassment, a protective order under Rule 26(c) may be appropriate. Do not simply ignore excessive requests; failing to respond still triggers deemed admissions.

One frequent mistake: objecting because a request calls for a “legal conclusion.” Rule 36 expressly permits requests about the application of law to fact and opinions about either. The 1970 amendment broadened the rule for exactly that reason.¹ A reflexive “legal conclusion” objection to a request that actually asks you to apply law to the facts of your case can backfire.

Weak objections carry their own cost. If the requesting party moves to determine sufficiency and wins, the court can overrule your objection, order you to answer, or deem the matter admitted. Expenses on that motion may be charged to the losing side under Rule 37(a).¹

Requests to Admit the Genuineness of Documents

Rule 36 also allows requests to admit the genuineness of a described document, typically with a copy attached. Assess whether the document is what it purports to be: is the signature authentic, is the copy accurate, has it been altered?¹ Admitting genuineness does not mean you agree with the contents. You can admit that a contract is authentic while disputing its interpretation or enforceability.

Format, Signature, and Service

The response is a litigation document, not a letter. Include a caption matching the case (court, case number, parties), a title identifying the paper as your response to the request for admissions, and numbered paragraphs that track each numbered request.¹

The response must be signed by the party or the party’s attorney. Under the current federal rule, the signature requirement replaced the former verification requirement, so the response does not need to be sworn. Some state courts still require verification or notarization for certain discovery responses; check local rules if you are in state court.¹

Serve the response on the opposing party. Responses generally are not filed with the court unless later used in a proceeding or the court orders filing. If you serve through the court’s electronic filing system, no separate certificate of service is required. For any other method, include a certificate of service documenting method and date.³

The Financial Risk of a Bad Denial

Rule 37(c)(2) creates a direct consequence for denying something the other side later proves true. If the requesting party has to spend time and money proving that fact at trial, they can move for an order requiring you to pay their reasonable expenses, including attorney fees, incurred in making the proof. The court must grant the motion unless one of four exceptions applies:⁴

The court sustained an objection to the request under Rule 36(a).
The admission sought was of no substantial importance to the case.
You had reasonable ground to believe you might prevail on that point.
Some other good reason existed for the failure to admit.

The default is that expenses are awarded. It is mandatory unless you fit an exception. Before denying any request, honestly assess whether you have a reasonable basis for the denial. Denying facts you know are true to force the other side to prove them is what this rule targets.

Fixing an Admission Later

Admissions are not permanent, but the escape hatch is narrow. Rule 36(b) allows you to move the court for permission to withdraw or amend an admission at any time, even during trial, and the burden is on you.¹ Two things must be shown:

Withdrawal must promote the presentation of the merits. Courts want cases decided on the actual facts, so this is usually satisfied when an admission was made in error or is contradicted by newly discovered evidence.
The other side must not be prejudiced in maintaining or defending the case on the merits. Relevant prejudice is not simply that they now have to prove the fact. It means concrete problems like lost evidence, unavailable witnesses, or reliance on the admission in shaping trial strategy.

Some circuits treat those two prongs as the entire analysis; others also consider factors like whether there was good cause for the original error. Either way, granting withdrawal is discretionary. Getting your responses right the first time matters more than hoping to fix them later.

Practical Drafting Principles

Admit what you cannot credibly contest. Refusing to admit the date a letter was mailed or the existence of a signed contract gains nothing and invites a fee award under Rule 37(c)(2). Admitting non-damaging facts also preserves credibility for the denials that matter.

Deny honestly. A good-faith denial forces the other side to prove a central claim at trial, which is a legitimate use of the rule. Indiscriminate denial of everything is not, and courts and opposing counsel notice the pattern.⁴

Use the “insufficient information” response only when it is genuinely true and only after a real inquiry. Overuse signals that you did not investigate or are avoiding a position, and courts have little patience for either.

Read each request carefully before writing a word. Every admission is conclusive for the case, every denial has to be defensible, and every objection has to have a solid basis. Careful, honest, specific answers keep the case on its merits and keep the fee shifting provisions off your back.
