If you don’t answer interrogatories, the consequences escalate in stages: you first waive the objections you could have raised, then face a motion to compel and an order to pay the other side’s attorney’s fees, then risk court sanctions that can include having key facts decided against you, having evidence or witnesses excluded, being held in contempt, or losing the lawsuit entirely by default judgment or dismissal. Under Federal Rule of Civil Procedure 33, you have 30 days from service to respond in writing and under oath.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties Every day past that deadline weakens your position, often in ways that can’t be undone.
The First Thing You Lose Is Your Objections
This is the consequence most people never see coming. Under Rule 33, any objection you don’t raise within the response deadline is waived.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties If a question was irrelevant, overly broad, invasive of attorney-client privilege, or asked you to do the other side’s homework, you had every right to refuse to answer. But only if you said so, in writing, before the clock ran out.
Once that window closes, the court can force you to answer questions you never should have had to answer in the first place. A judge has discretion to excuse a late objection for good cause, but that’s an uphill fight. The practical effect of silence is that you hand the other side broader discovery rights than the rules actually give them.
The Opposing Lawyer Has to Reach Out First
When your answers are overdue, the opposing attorney can’t run straight to the judge. Federal Rule 37 requires the moving party to certify that they first made a good-faith effort to resolve the dispute without court involvement.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions In practice, the other lawyer will call or email, spell out what’s missing, and give you a short window to comply.
This is your last clean chance to respond without judicial consequences. Many discovery problems get resolved here. Ignore this outreach, and you’ve handed the opposing attorney exactly what they need for the next step.
Motion to Compel and the First Bill
When the informal attempt fails, the other side files a Motion to Compel, a formal request asking the judge to order you to answer. Rule 37 specifically authorizes this motion when a party fails to answer interrogatories served under Rule 33.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
The court will schedule a hearing. The opposing lawyer will walk the judge through the timeline: when the interrogatories were served, when the deadline passed, what efforts were made to resolve it informally. You’ll get a chance to explain, but judges have heard every excuse and are rarely moved by neglect or disorganization.
If the judge grants the motion, two things happen. You get a new, court-ordered deadline to provide complete answers. This is no longer a procedural obligation between parties; it’s a direct command from the judge, and violating it carries far steeper penalties. And the judge will almost certainly order you to pay the other side’s reasonable expenses for having to file the motion, including attorney’s fees.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions The rule says the court “must” order this payment, with only three narrow exceptions: the other side filed without first trying to confer in good faith, your position was substantially justified, or the award would be unjust for some other reason.
How much those fees run depends on the work the attorney put in and their billing rate. The point is that your inaction is now costing real money, on top of whatever the lawsuit itself costs.
What Happens If You Ignore the Court’s Order
Ignoring a court order to answer interrogatories is a fundamentally different problem than missing the original deadline. At this stage you’re no longer failing to cooperate with the other party; you’re defying the judge. Rule 37 gives the court a toolkit of escalating penalties, and judges have wide latitude to pick the combination that fits.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
Facts Decided Against You
The court can order that specific facts are treated as proven against you. If you refused to answer questions about the condition of your brakes before a car accident, the judge could declare that, for purposes of the lawsuit, your brakes were defective. You’d be barred from arguing otherwise at trial. The sanction directly fills in the gap your silence created, and it fills it in the way that hurts you most.
Evidence and Witnesses Excluded
The court can also prohibit you from introducing certain evidence or calling witnesses to support your side. Ignore interrogatories that asked you to identify your witnesses, and the judge can bar those witnesses from testifying at trial. You lose parts of your case not because the facts are against you, but because you refused to engage with the process.
Case Frozen, Contempt, More Fees
A judge can freeze the entire case until you comply, which sounds neutral but often works against the non-compliant party by running up costs and delaying resolution. More seriously, the court can treat continued disobedience as contempt of court.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions A contempt finding can carry additional fines and, in extreme circumstances, jail time. This is the point at which a discovery dispute stops being just a litigation problem.
More monetary sanctions ride along with these penalties. The rule requires the court to order the disobedient party or their attorney to pay the other side’s reasonable expenses caused by the failure, unless the noncompliance was substantially justified or the award would be unjust.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions These costs stack on top of what was awarded at the motion-to-compel stage.
Losing the Case Entirely
The most extreme sanction is losing the lawsuit outright. If you’re the defendant, the court can strike your answer and enter a default judgment against you, meaning the plaintiff wins without ever having to prove the case at trial.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions If you’re the plaintiff, the court can dismiss your lawsuit in whole or in part, ending your claims permanently.
Courts treat this as a last resort, reserved for willful and repeated noncompliance. Rule 37 doesn’t explicitly require judges to exhaust lesser sanctions first, but in practice most courts will impose intermediate penalties before jumping to a case-ending one. The advisory committee notes clarify that “willfulness” isn’t a formal prerequisite for any sanction, though it’s clearly relevant to which sanctions a judge selects. A pattern of ignoring deadlines, ignoring the meet-and-confer process, and then ignoring the court’s own order makes the case for a terminal sanction almost impossible to fight.
A default against a defendant leads to a damages hearing. You’ve lost your ability to contest liability; the only question left is the dollar amount. For a plaintiff whose case gets dismissed, the result is equally final. Years of litigation can evaporate because of what started as not responding to a set of written questions.
If the Questions Seem Unfair, Object Instead
If you’ve received interrogatories that look invasive, excessive, or irrelevant, the right move is never to ignore them. The rules give you real tools to push back, but only if you use them inside the response deadline. Under Rule 33, you must state each objection with specificity, or it’s waived. Federal rules also cap interrogatories at 25 questions per party, including subparts, unless the court allows more, and a set that clearly exceeds that limit is one legitimate basis to push back.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties
Discovery is limited to information relevant to a claim or defense and proportional to the needs of the case. Objections that commonly hold up include:
- Privilege. The question asks for information protected by attorney-client privilege or the work-product doctrine.
- Relevance. The question has nothing to do with any claim or defense. A question about your medical history in a contract dispute, for instance, would likely be irrelevant.
- Undue burden. Answering would require disproportionate effort relative to the value of the information. Asking a small business to compile ten years of every customer transaction might qualify.
- Vagueness. The question is so unclear you genuinely can’t tell what’s being requested.
- Exceeds the question limit. The interrogatories go beyond the 25-question cap without court permission.
Boilerplate objections that string together every possible ground without explaining which ones apply to which questions tend to backfire. Judges see through them immediately, and some courts treat blanket objections the same as no objection at all. State the ground, explain briefly why it applies, and if part of the question is answerable, answer that part. Partial compliance paired with targeted objections is always a stronger position than silence.
