Can You Object to Interrogatories? Grounds, Deadlines, and Form

Yes, you can object to interrogatories in federal court, and Federal Rule of Civil Procedure 33 gives you 30 days from service to do it. The objection has to state its grounds with specificity, cover only what is actually objectionable, and travel alongside answers to whatever portion of the question is legitimate. Miss the 30-day window without a written extension or good cause, and Rule 33(b)(4) waives the objection whether it would have been a winner or not.¹

The 30-Day Deadline and What Waiver Means

Rule 33(b)(2) gives the responding party 30 days after service to answer or object. The parties can agree in writing to extend that period, and the court can shorten or extend it on its own, but the agreement has to be in writing and cannot collide with a court-set discovery cutoff or trial date.¹

What happens if the deadline passes without a response? Rule 33(b)(4) says any ground not stated in a timely objection is waived unless the court, for good cause, excuses the failure.² Waiver is exactly as harsh as it sounds. The question could have been abusive, irrelevant, or laden with privileged material; if you did not raise the objection on time, you cannot raise it later. Courts have held that the opposing side’s informal willingness to wait past 30 days is not an extension. If you need more time, get it in writing through a stipulation or a court order. A casual email will not save you when the other side moves to compel, and “I was busy” is not good cause.

Waiver has one limit worth knowing. Even where objections are gone, the court still evaluates whether the interrogatory itself fits within Rule 26(b)(1)’s scope and proportionality requirements. Losing your objections does not force a judge to enforce an improper question.

Grounds That Actually Work

Discovery under Rule 26(b)(1) reaches nonprivileged information relevant to any party’s claim or defense and proportional to the needs of the case.³ Every solid objection ties back to one of those two limits or to the form of the question itself.

Privilege

Attorney-client privilege shields confidential communications between lawyer and client made to obtain legal advice. Other privileges — spousal, doctor-patient, clergy-penitent — apply depending on the jurisdiction and the case. A privilege objection is not a refusal to say anything. Rule 26(b)(5)(A) requires the withholding party to describe the nature of what is being withheld in enough detail for the other side and the court to test the claim.³ In practice, that means a privilege log identifying each withheld item, the privilege claimed, and the basis. Skip the log and courts often treat the privilege as waived.p>

Irrelevance

If an interrogatory has no connection to any claim or defense in the case, it is not discoverable. The bar is low because discovery is intentionally broad, and information does not have to be admissible at trial to be discoverable. Pure fishing expeditions with no tie to the dispute are the fair targets.

Overbreadth and Vagueness

A question that sweeps too wide or leaves key terms undefined is objectionable on its face. “Describe every communication you have ever had about the subject matter of this lawsuit,” with no time frame and no specificity, is the textbook overbreadth example. Vagueness is related but distinct: the terms are so unclear you cannot tell what is being asked. Courts evaluate breadth by asking whether the question targets pertinent information or imposes unreasonable demands well beyond what the case requires.

Undue Burden and Disproportionality

A relevant, well-drafted interrogatory can still be objectionable if answering it would impose a disproportionate burden. Rule 26(b)(1) lists the factors: the importance of the issues at stake, the amount in controversy, the parties’ relative access to relevant information, the parties’ resources, the importance of the discovery in resolving the issues, and whether the burden or expense outweighs the likely benefit.³ An interrogatory demanding twenty years of records in a modest contract dispute is the kind of thing that fails the proportionality test. Explain the specific burden. Vague claims that answering would be “too hard” get overruled fast.

Form Problems

Some objections target how a question is written rather than what it seeks:

Compound questions that bundle unrelated inquiries together, effectively circumventing Rule 33(a)(1)’s 25-interrogatory cap on discrete subparts. Courts look at substance, not numbering; “State your name, address, and date of birth” is three subparts even if labeled as one.¹
Questions that call for legal conclusions, like “Do you admit you were negligent?” These ask you to apply law to facts rather than provide facts.
Questions that call for speculation about hypotheticals or events you have no way of knowing.

Form objections are common, and overusing them is risky. A judge who sees “vague, ambiguous, overly broad, and unduly burdensome” copied across twenty-five responses will overrule every one and may award the other side’s attorney fees for the trouble.

How the Objection Has to Be Written

Getting the grounds right is only part of the work. The procedural requirements are strict, and small mistakes forfeit real rights.

Specificity, Not Boilerplate

Rule 33(b)(4) requires each objection to state its grounds with specificity.¹ A general recitation that a question is “overly broad, unduly burdensome, and not reasonably calculated to lead to the discovery of admissible evidence,” with no explanation, is boilerplate. Federal courts routinely overrule those. Explain how the specific interrogatory is overly broad, what specific burden it imposes, or why the particular information is irrelevant. The more concrete, the more likely the objection holds.

Answer What You Can

Rule 33(b)(3) requires each interrogatory to be answered separately and fully in writing under oath, to the extent it is not objected to.¹ If part of a question is objectionable and part is legitimate, state the objection and then answer the rest. Refusing to answer an entire interrogatory because one aspect of it is flawed is a common error, and courts do not treat it charitably.

Signatures

The person answering must sign the answers, and the attorney must sign the objections.¹ Answers are given under oath, so inaccurate or incomplete responses carry the same weight as any other sworn statement. For a corporation or other organization, any officer or agent with access to the information can answer for the entity.

Meet and Confer Before Anyone Files a Motion

The federal rules do not allow either side to jump straight to the judge. Rule 37(a)(1) requires any motion to compel discovery to include a certification that the movant tried in good faith to confer with the other party first, and the same requirement applies to motions for protective orders under Rule 26(c).⁴³

Good faith means meaningful two-way communication and a real attempt to narrow the dispute, not a single letter fired off for the record. Many local rules go further, requiring phone calls or in-person meetings. Filing a motion to compel without a proper conference is one of the quickest ways to get it denied and end up owing the other side’s costs.

What Happens When the Court Rules

If the parties cannot resolve the dispute, the requesting party can file a motion to compel under Rule 37(a). The objecting party then bears the burden of showing the objection is valid.⁴ The judge measures the objection against Rule 26(b)(1)’s relevance and proportionality framework and the specific facts of the dispute. For privilege claims, a judge may conduct an in camera review, examining the disputed materials privately to decide whether the privilege applies. That review is discretionary, used when the claim is unclear or cannot be adequately explained without exposing what the privilege is meant to shield.

Instead of a straight up-or-down ruling, the court can issue a protective order under Rule 26(c). Protective orders can forbid certain inquiries, restrict who sees the information, require confidential treatment of trade secrets, or adjust timing and method. The party seeking one must show good cause, which courts evaluate flexibly.³

Cost Shifting

The financial stakes are built into Rule 37. When the court sustains the objection and denies the motion to compel, it may require the moving party or attorney to pay the objecting party’s reasonable expenses, including attorney fees, unless the motion was substantially justified or an award would be unjust.⁴

When the court overrules the objection and grants the motion, it must generally order the objecting party or attorney to pay the movant’s reasonable expenses, again including attorney fees. Three narrow exceptions apply: the moving party did not attempt a good-faith conference first, the objection was substantially justified even though overruled, or an award would be unjust.⁴

Mixed results are common. Judges frequently narrow an overly broad interrogatory to a time period or subject area, or sustain a privilege objection while overruling an overbreadth objection on the same question. When the outcome is split, the court has discretion to split the costs however it sees fit. And if a court orders you to answer and you still refuse, Rule 37(b)(2) opens the door to sanctions ranging from deemed admissions and evidence exclusion up to striking pleadings, default judgment, or contempt.⁴

Your Duty to Supplement

Answering interrogatories is not a one-time event. Rule 26(e) requires a party who has responded to supplement or correct the response in a timely manner upon learning that it was materially incomplete or incorrect, unless the additional information has already been made known to the other parties during discovery or in writing.³ The obligation runs through trial. There is no fixed date for supplementation, but “timely” means soon after you learn the answer needs updating. Failing to supplement can lead to exclusion of the undisclosed information at trial, a sanction that can quietly gut a case before a jury ever hears it.

A Note on State Court

Everything above comes from the Federal Rules of Civil Procedure and applies in federal court. Many states model their discovery rules on the federal framework, but interrogatory limits, response deadlines, and proportionality standards vary. If your case is in state court, check that state’s rules of civil procedure rather than assuming the federal answer carries over.
