What Happens if You Don’t Answer Interrogatories?

Interrogatories are written questions one party sends another during a lawsuit. They can ask for facts, identify witnesses, or request information about a claim or defense. Ignoring them can lead to a motion to compel, court-ordered deadlines, and—in some cases—serious sanctions. The exact rules depend on the court and jurisdiction, but a missed deadline is best addressed quickly. Knowing how interrogatories work and what to do if answers are late can help a party avoid making a manageable discovery problem worse.

What Interrogatories Require

Interrogatories are a form of written discovery in a civil lawsuit. Unlike a deposition, which involves live questions and answers, interrogatories are served in writing and answered in writing. Under the federal rules, a party may serve interrogatories on another party, but generally not on a person or business that is not a party to the case.

Questions may seek information about events, people with relevant knowledge, documents, calculations, or the basis for a party’s legal claims and defenses. A response may need to provide the information available to the responding party after a reasonable inquiry. A party cannot necessarily avoid answering simply because another person or a record may also know the information.

Federal Rule of Civil Procedure 33 generally limits each party to 25 interrogatories, including discrete subparts, unless the parties agree to more or the court allows additional questions. State court limits and procedures can differ. The rule that applies is generally the one governing the court where the case is pending.

How Long Does a Party Have to Answer?

In federal court, the usual deadline is 30 days after interrogatories are served. Rule 33 allows a different period if the parties stipulate or the court orders one. A defendant served with interrogatories before that defendant’s answer is due generally has 45 days after service of the summons and complaint to respond, unless the parties agree or the court orders otherwise.

Service method and court-specific orders can affect how a deadline is calculated. State rules may set a different response period, and a scheduling order or agreement may change the usual deadline. A party should check the applicable rules, case orders, and proof of service rather than assume the federal 30-day period applies.

If the deadline is approaching, the responding party can ask the other side in writing for an extension. The request should be made before the deadline where possible, and any agreement should be documented. An informal request does not automatically extend the deadline: the other side must agree, or the court must grant an extension when required.

What Happens If Interrogatories Go Unanswered?

A missed deadline does not usually mean the unanswered questions automatically become true or that the case is immediately lost. But it does leave the responding party exposed to a request for court intervention. The requesting party may seek an order requiring answers, and continued noncompliance can produce escalating consequences.

The other party may try to resolve the dispute

Before asking a federal court to compel discovery, the requesting party generally must make a good-faith effort to resolve the issue without court action. The parties may discuss the missed responses, clarify disputed questions, and agree on a firm date for complete answers. Local rules may spell out how this discussion must happen.

The other party may file a motion to compel

If no resolution is reached, a party may ask the court for an order compelling answers under Federal Rule of Civil Procedure 37(a). The motion typically explains which interrogatories remain unanswered and describes the efforts made to obtain a response. State rules set their own procedures and may require specific meet-and-confer steps or supporting documents.

The court may order the responding party to answer by a particular date. It may also address the costs of the motion. Under the federal rule, if a motion to compel is granted—or the requested discovery is provided only after the motion is filed—the court generally must require the party or attorney responsible for the nonresponse to pay reasonable expenses, including attorney’s fees. Exceptions can apply, including when the movant did not make a good-faith effort, the failure was substantially justified, or other circumstances make an award unjust.

The court may impose sanctions

Failure to serve interrogatory answers can support a motion for sanctions under Rule 37(d). A court may order sanctions without first issuing an order compelling answers, although the rule requires the moving party to certify a good-faith effort to resolve the issue. Federal sanctions can include reasonable expenses and certain measures listed in Rule 37(b)(2)(A), subject to the rule’s requirements and the circumstances of the case.

Depending on the conduct and procedural history, court-ordered measures may include treating specified facts as established, preventing a party from supporting certain claims or defenses, striking pleadings, staying the case, dismissing an action, or entering a default judgment. These are serious outcomes, not automatic results of a single missed deadline. Courts generally consider the applicable rule, the reason for noncompliance, prejudice to the other side, and whether the party followed court orders.

Can Unanswered Interrogatories Be Treated as Admissions?

Interrogatories and requests for admission are different discovery tools. Under the federal rules, a failure to answer an interrogatory does not, by itself, automatically make every question’s premise an admitted fact. A request for admission has a separate rule: under Rule 36, a matter may be deemed admitted if the party fails to respond or object within the applicable time, unless the court allows a withdrawal or amendment.

That distinction does not make interrogatories safe to ignore. A court may impose sanctions or establish facts as a sanction for discovery misconduct in an appropriate case. And a missed interrogatory response can interfere with preparation for depositions, motions, or trial. The specific result depends on the rule, court orders, and case circumstances.

What Makes an Interrogatory Response Proper?

A response should answer each question fully and separately, subject to any valid objection. Under federal Rule 33, answers must be in writing and under oath. The responding party—not just the attorney—must sign the answers. The attorney signs objections. Responses should be accurate after a reasonable effort to gather available information.

A party that cannot answer fully should provide the information that is available and explain what cannot be answered. A vague statement such as “the party will supplement later” may not meet the obligation to provide information currently known or reasonably available. If a party later learns that a response is materially incomplete or incorrect, the duty to supplement or correct may apply under Rule 26(e).

Objections should identify the grounds specifically. A party should not rely on a general objection to every question or use objections as a reason to withhold information that is not actually disputed. If only part of a question is objectionable, the party may need to answer the unobjectionable part while stating the objection to the rest. Privileged information requires particular care: the party should assert the privilege appropriately and avoid disclosing protected material.

Federal Rule 33 also allows an answer to refer to business records in certain circumstances, but only if the burden of deriving the answer is substantially the same for either side and the responding party identifies the records in enough detail for the other party to locate them. Simply pointing broadly to a large collection of documents may not satisfy this rule.

What to Do If the Deadline Has Passed

A late response is usually better than continued silence. A party who missed the deadline should review the interrogatories, applicable rules, and any scheduling or discovery orders, then act promptly. If the answers are ready, serving complete, signed responses may reduce the dispute, although it does not necessarily eliminate the risk of a motion, fees, or sanctions.

1. Check the deadline and service details. Confirm when and how the questions were served, what response period applies, and whether an extension or court order changed it.
2. Contact the other side. Explain the delay briefly, propose a realistic date for responses, and request written confirmation of any extension or resolution.
3. Prepare accurate answers and specific objections. Answer each question separately, provide available information, and avoid unsupported guesses or blanket objections.
4. Comply with court orders. If a judge has ordered a response by a set date, missing that date can make the situation substantially more serious.
5. Consider legal advice promptly. An attorney can assess objections, privilege concerns, court rules, and whether a motion for an extension or protective order is appropriate.

If a party cannot respond because a question is unclear, overly burdensome, outside the permitted scope of discovery, or seeks privileged information, the party should raise the issue through a timely, rule-compliant objection or seek court protection where appropriate. Silence is not a substitute for a valid objection. The exact deadline for raising objections and the consequences of missing it can vary by jurisdiction and circumstance.

When the Questions Seem Improper or Too Difficult

Discovery is generally limited to nonprivileged information relevant to a claim or defense and proportional to the needs of the case under Federal Rule 26. A party may object to an interrogatory on a valid basis, such as privilege or an excessive burden, but should explain the basis rather than simply refuse to respond. The court can decide whether an objection is justified and whether an answer, a narrower question, or no response is appropriate.

When the burden is the concern, the responding party can describe the specific work involved and propose a reasonable alternative, such as narrowing the time period or limiting the subject. A party who believes discovery is improper may also seek a protective order under Rule 26(c), following the required consultation process. Whether a question is objectionable depends on the facts and the governing court rules.

Federal Rules and State Court Rules Can Differ

The federal rules provide a useful framework, but they do not govern every lawsuit. State courts have their own civil procedure rules, deadlines, discovery limits, and sanction standards. Some state systems also have specialized procedures for family, small claims, or other case types. Local rules and a judge’s orders can add requirements, too.

For federal cases, the primary references include Federal Rule of Civil Procedure 33 on interrogatories, Rule 26 on discovery scope and supplementation, and Rule 37 on motions to compel and sanctions. The official federal rules are also available through the U.S. Courts website. These sources do not replace the rules and orders applicable to an individual case.

Key Takeaways About Ignoring Interrogatories

• Do not assume the questions disappear when a deadline passes. The other side may seek a court order and request expenses or sanctions.
• Answers are not automatically admissions. Interrogatories differ from requests for admission, though a court can impose serious consequences for discovery violations.
• Respond promptly and specifically. Provide accurate answers under oath, state any valid objections clearly, and follow applicable signing requirements.
• Rules vary. Deadlines, procedures, and possible sanctions depend on the jurisdiction, court orders, and facts of the case.
