Under Federal Rule of Civil Procedure 33(b)(2), you have 30 days from the date interrogatories are served to serve your written answers and any objections.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties That is how long you have to answer interrogatories in federal court. State courts set their own windows, generally somewhere between 20 and 50 days. Missing the deadline is not a minor slip. It can wipe out your right to object and open the door to court-ordered penalties.
The 30-Day Federal Clock
Rule 33(b)(2) is the baseline for federal cases: answers and objections are due within 30 days after service.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties Your answers must be in writing and signed under oath.
State deadlines are different, and some courts give defendants extra time for the first set of interrogatories served with the complaint, sometimes up to 45 days. Others cut the window as short as 20. If your case is in state court, check that court’s rules of civil procedure rather than assuming the federal number applies.
Counting the Days Correctly
The 30-day clock does not start the day the interrogatories arrive. Under Rule 6(a), you exclude the day of service and start counting the next day.2Legal Information Institute. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time; Time for Motion Papers Weekends and holidays count. If the 30th day lands on a Saturday, Sunday, or legal holiday, the deadline rolls forward to the next business day.
Service method also matters. When interrogatories are served by mail, you get three extra days on top of the 30.2Legal Information Institute. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time; Time for Motion Papers Electronic service gets no such cushion. Because most discovery today is served electronically, 30 days is usually the firm cutoff.
What Happens If You Miss the Deadline
The penalties escalate in stages, each one worse than the last.
First, you waive your objections. Any objection you did not raise in a timely response is forfeited, and you cannot resurrect it later unless the court finds good cause for the delay.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties Questions you had every right to challenge may now have to be answered.
Second, the other side can file a motion to compel. If the court grants it, you will almost certainly be ordered to pay the moving party’s reasonable expenses, including attorney’s fees. The court can skip the fee award only if your failure was substantially justified or other circumstances make the award unjust.3Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
Third, if you ignore a court order compelling your answers, the judge can impose sanctions that go well beyond fees. The court may:
- Treat the facts covered by the unanswered interrogatories as established in the other party’s favor.
- Bar you from presenting certain evidence or raising specific defenses at trial.
- Strike some or all of your claims or defenses from the case.
- Enter a default judgment against you, ending the case without a trial.
Courts generally start with the lightest sanction available and escalate from there, but judges have broad discretion, and willful or repeated noncompliance can accelerate the timeline.3Legal Information Institute.

Getting More Time
If 30 days is not realistic, you have two routes.
The easier one is to ask the other side. Under Rule 29, the parties can agree in writing to modify discovery deadlines without going to the court, as long as the new timeline does not interfere with court-ordered dates for motions, hearings, or trial.4Legal Information Institute. Federal Rules of Civil Procedure Rule 29 – Stipulations About Discovery Procedure If the extension would push past those court dates, you need the judge’s approval.
If opposing counsel refuses, file a motion for an extension. Under Rule 6(b), the court can extend a deadline for good cause.2Legal Information Institute. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time; Time for Motion Papers Timing is everything. File before the original deadline runs out. Wait until after it passes and the standard tightens to “excusable neglect,” which is harder to meet. Volume and complexity of the questions, trouble locating records, or the unavailability of the person with the answers are all reasons courts will consider.
Objections Are Due on the Same Deadline
This is where parties get burned. Objections run on the same 30-day clock as your answers. You cannot stay silent for a month and then raise objections later.1Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties
When you do object, state the grounds with specificity. A vague complaint that a question is “burdensome” without explaining why will not hold up. If only part of an interrogatory is objectionable, you still have to answer the rest; a partial objection is not a free pass on the whole question.
The Obligation Does Not End at Day 30
Serving your answers on time is not the end of it. Rule 26(e) imposes a continuing duty to supplement your responses if you later learn that what you provided was incomplete or incorrect in some material way.5U.S. District Court, Northern District of Illinois. Federal Rules of Civil Procedure Rule 26 – General Provisions Regarding Discovery; Duty of Disclosure This applies at appropriate intervals throughout the case.
If you identify a new witness, find additional documents, or realize an earlier answer was wrong, update the other side promptly. The sanctions for failing to supplement are the same ones that apply to a missed initial response, including exclusion of the evidence or witness you never disclosed.
