Subpoenas do not expire on a set date. A subpoena is tied to the case it came from, and your obligation to comply lasts until you satisfy it, the case ends, the party who issued it withdraws it in writing, or a court quashes it. The date printed on the face of the subpoena is a compliance date, not an expiration date. Letting it pass without acting does not release you.
What Actually Ends Your Obligation
A subpoena stays enforceable until one of four things happens.
- You comply. If you were called to testify, your duty ends when you finish your appearance. If you were called to produce documents (a subpoena duces tecum), it ends when you have handed over everything the subpoena describes. Some subpoenas require both, and both boxes have to be checked.
- The underlying case ends. If the parties settle, the court dismisses the matter, or a final judgment is entered, outstanding subpoenas lose their force. No case, no proceeding to compel your participation in.
- The issuing party withdraws it. The attorney or party who requested the subpoena can formally cancel it. Get that release in writing.
- A court invalidates it. A judge can quash or modify a subpoena by order, which terminates your duty entirely or narrows what you have to do.
Until one of those things happens, the passage of time by itself changes nothing.
A Postponed Date Does Not Kill the Subpoena
This is where people talk themselves into trouble. The original hearing gets rescheduled, or the deposition is pushed back, and the date on the subpoena comes and goes. They assume they are off the hook. They are not. A properly served subpoena remains in effect for any rescheduled dates within the same proceeding.
The attorney who issued the subpoena should send you written notice of the new date. Do not rely on a voicemail or a message from someone else. If the new date creates a genuine conflict, contact the issuing attorney and try to work it out; most will accommodate a reasonable request. If you cannot reach an agreement, the correct move is to file a motion with the court asking to be excused. Skipping the rescheduled date is not the correct move.
The Deadlines That Do Run Against You
Even though the subpoena itself is not on a clock, you are. If you want to push back, the rules give you a short window.
To object to a document subpoena in writing, you have to serve your objection on the requesting party before the compliance date or within 14 days after service, whichever comes first.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena Missing that window can be treated as a waiver of your right to object at all.
To ask the court itself to cancel or narrow the subpoena, you file a motion to quash. Federal rules require the motion to be “timely,” and courts overwhelmingly read that to mean filed before the compliance date on the subpoena. The practical rule: if something about the subpoena is wrong, act quickly. Waiting for the date to pass and then complaining that the subpoena was unfair is not a strategy that works.
Getting Out of a Subpoena the Right Way
A motion to quash asks the court to declare the subpoena invalid or to trim its scope. If the judge grants it, you are legally excused, either fully or to whatever extent the court decides.
Under the federal rules, a court must quash or modify a subpoena that:
- fails to allow a reasonable time to comply;
- requires travel or production beyond the geographic limits set by the rules;
- demands privileged or otherwise protected material, such as attorney-client communications, doctor-patient information, spousal communications, or trade secrets; or
- imposes an undue burden, meaning compliance would be unreasonably expensive, time-consuming, or disruptive compared to the value of what is being sought.
These grounds are set out in Rule 45 and the official subpoena form.2United States Courts. AO 88B – Subpoena to Produce Documents, Information, or Objects or to Permit Inspection of Premises in a Civil Action Improper service is a separate ground. If the subpoena was not delivered to you the way the rules require, generally by personal delivery, a court may throw it out on that basis alone.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena
On the geographic point, federal subpoenas can compel your attendance at a trial, hearing, or deposition only within 100 miles of where you live, work, or regularly do business in person. Parties to the case, and their officers, can be required to attend anywhere within the state. Document production is capped at the same 100-mile radius from where you reside, work, or transact business.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena A subpoena that ignores those limits is a strong candidate for a motion to quash.
Grand Jury Subpoenas Are Different
Grand jury subpoenas do have a rough outside limit, though it is a long one. A federal grand jury sits for at least 18 months, and a court can extend that term by up to 6 more months in the public interest.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury A subpoena from that grand jury generally stays valid for the life of its term.
These are harder to fight than civil subpoenas. The grounds for quashing are narrower, the proceedings are secret, and courts give prosecutors substantial room. Refusing to comply can lead to confinement until you cooperate, though that confinement cannot exceed the life of the grand jury’s term and in no event more than 18 months.4Office of the Law Revision Counsel. 28 USC 1826 – Recalcitrant Witnesses
What Happens if You Ignore It
A subpoena is a court order. Ignoring one exposes you to contempt of court, which federal courts can punish by fine, imprisonment, or both.5Office of the Law Revision Counsel. 18 USC 401 – Power of Court Rule 45 specifically authorizes the court where compliance is required to hold in contempt anyone who, having been properly served, fails without adequate excuse to obey.1Legal Information Institute. Federal Rule of Civil Procedure 45 – Subpoena
Contempt comes in two flavors. Civil contempt is meant to force you to comply; the fine or jail time ends the moment you do what the subpoena requires. Criminal contempt punishes the disobedience itself, and the sentence is fixed regardless of what you do afterward.6Legal Information Institute. Contempt of Court
Contempt is not the only risk. A judge can issue a bench warrant directing law enforcement to bring you in. The court can order you to pay the legal fees the other side ran up trying to enforce the subpoena. In civil cases, a judge can also instruct the jury to draw an adverse inference from your refusal, treating whatever you would not produce as evidence that would have hurt your side. And none of this requires a new lawsuit. The judge in the underlying case already has the authority to act, often on short notice.
So if you have received a subpoena and the date on it is approaching or has already passed, the safe assumption is that you are still on the hook. Comply, get a written withdrawal, or move to quash. Silence is the option with the worst downside.
