A failure to answer interrogatories on time costs you first, and quietly: the moment the 30-day deadline passes, you lose the right to object to the questions. From there the consequences escalate through court orders, attorney’s fee awards, evidence and issue sanctions, and, in serious cases, dismissal, default judgment, or contempt. Under the Federal Rules of Civil Procedure, a party served with interrogatories has 30 days to provide sworn, written answers, and most state courts follow a similar framework.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties
You Waive Your Objections Automatically
This is the consequence most people miss. Any objection you fail to raise in a timely response is waived under the federal rules.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties If a question invaded attorney-client privilege, demanded trade secrets, or was plainly overbroad, staying silent past day 30 usually costs you that argument.
Courts can excuse the waiver for “good cause,” but the bar is high. You need a genuinely compelling reason for the late objection, not a forgotten calendar entry. And if you ignored the interrogatories entirely, you cannot later argue they were objectionable as a defense for not responding, unless you had already filed a motion for a protective order before the deadline expired.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions The practical effect is that you may have to disclose information you could have legitimately withheld.
Ask for More Time Before the Deadline Passes
If you see the deadline coming and cannot finish, the cleanest fix is to email opposing counsel and ask for an extension. The federal rules let parties stipulate to modified discovery deadlines without involving the court, as long as the extension does not push into a scheduled hearing, trial date, or discovery cutoff.3Legal Information Institute. Federal Rules of Civil Procedure Rule 29 – Stipulations About Discovery Procedure An initial 30-day extension is common and rarely refused. If the extension would run past a court deadline, the judge has to sign off.
If the other side refuses, or the deadline has already gone by, you can file a motion. Before expiration, the court can extend the time for good cause. After expiration, the standard tightens: you must show the delay was the result of “excusable neglect,” which requires more than simple inattention.4United States Courts. Federal Rules of Civil Procedure – Rule 6(b) Ask before you need to, not after.
What the Other Side Can Do
Meet and Confer First
The opposing party cannot immediately run to the judge. Before filing any discovery motion, the federal rules require a good-faith effort to resolve the dispute directly.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions In practice, that means a letter or email identifying the unanswered interrogatories, referencing the original deadline, and setting a new one, usually with a warning that a motion will follow. Some courts require the parties to actually speak by phone or in person. Skipping this step is fatal to the motion that comes next: any filing must include a sworn certification that the effort was made, and judges can deny the motion outright if it was not.
Motion to Compel
When informal efforts fail, the requesting party files a motion to compel, formally asking the judge to order answers. The motion has to describe the overdue discovery, the informal efforts made, and why intervention is necessary. A motion to compel is not limited to zero-response situations. Evasive or incomplete answers count as a failure to respond for purposes of the rule, so vague, noncommittal answers can land you in the same place as silence.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
If the judge grants the motion, you are ordered to answer by a specific date. The judge will also typically order you to pay the other side’s attorney’s fees for having to bring the motion. Fee shifting is not discretionary here. The rule says the court “must” award expenses unless the failure was substantially justified or other circumstances make an award unjust.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
Total Non-Response: The Fast-Track to Sanctions
The path above assumes a gradual escalation. When a party serves no answers at all, the rules offer the other side a faster route. The opposing party can move directly for sanctions, including case-ending sanctions, without first obtaining an order to compel.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
The available sanctions match those for violating a court order: the judge can declare facts established, bar you from introducing evidence, strike your pleadings, dismiss the case, or enter a default judgment. On top of whichever sanction the court chooses, the rule requires the non-responding party and their attorney to pay the reasonable expenses caused by the failure. And you cannot defend against this motion by arguing the interrogatories were objectionable. Your remedy for improper questions was to file timely objections or seek a protective order, not to ignore them.2Legal Information Institute.

Sanctions for Violating a Court Order
Once a judge has granted a motion to compel and set a new deadline, ignoring that order changes the picture. You are no longer just uncooperative in discovery; you are defying a direct judicial order. The penalties climb quickly.
- Monetary sanctions. The court orders you to pay the other side’s attorney’s fees and expenses for the enforcement motion.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
- Evidence sanctions. The court bars you from introducing certain evidence at trial, particularly evidence tied to the unanswered interrogatories.
- Issue sanctions. The court declares specific facts established in the opposing party’s favor, removing disputed issues from trial.
- Terminating sanctions. The court strikes your pleadings. For a plaintiff, that means dismissal. For a defendant, default judgment.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
- Contempt of court. In cases of willful defiance, a party or their attorney can be held in contempt, which carries fines or jail time.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
Judges usually apply these penalties in order, starting with money and moving up if the defiance continues. Terminating sanctions and contempt are reserved for persistent, willful refusals. The progression is not guaranteed, though. A judge who concludes a party is acting in bad faith from the start has the authority to impose severe sanctions without working through the lighter options first.
The practical answer to the original question is short. Answer on time. Ask for an extension the moment you know you cannot. Put objections in writing before day 30. Every step you skip makes the next consequence harder to avoid.
