What Happens If You’re Subpoenaed as a Witness and Don’t Show Up?

If you’re subpoenaed as a witness and don’t show up, the court can hold you in contempt, issue a warrant for your arrest, fine you, and in federal cases confine you for up to 18 months until you agree to testify.¹ A subpoena is a court order, not a request, and judges treat silence as defiance. But if you have a legitimate reason you can’t appear, there are proper ways to raise it — and they all require you to act before the hearing date, not after.

Contempt of Court Is What You’re Facing

Courts have inherent authority to punish disobedience of their orders by fine, imprisonment, or both. Federal law defines contempt to cover any disobedience or resistance to a court’s lawful order, writ, or command.² Before a contempt finding is entered against you, the court holds a hearing where you get a chance to explain why you didn’t appear.³ What happens at that hearing depends on whether the judge classifies the contempt as civil or criminal.

Civil Contempt

Civil contempt is forward-looking. The sanctions are designed to pressure you into complying, not to punish you for the past. That can mean escalating daily fines or confinement that lasts until you agree to testify. A person held in civil contempt is often described as holding the keys to the jailhouse cell in their own pocket: cooperation ends the confinement. Under the federal recalcitrant witness statute, a judge can summarily order confinement until you comply, though it cannot exceed the life of the court proceeding or 18 months, whichever is shorter.¹

Criminal Contempt

Criminal contempt punishes past behavior. Agreeing to testify later doesn’t erase it, because the penalty addresses the fact that you already defied the court. Where the contempt also constitutes a criminal offense, federal law caps the fine at $1,000 for an individual and the imprisonment at six months.⁴ Because the sanction is punitive, you get the procedural protections of a criminal defendant, including proof beyond a reasonable doubt.

A Bench Warrant Can Follow You for Years

If you don’t appear, the party that needed your testimony can ask the judge to compel your attendance.⁵ The judge’s standard tool is a bench warrant — an arrest warrant issued directly from the bench that authorizes law enforcement to find you, arrest you, and bring you to the courthouse. Bench warrants do not expire on their own. They stay active until the court resolves the matter, so an officer who runs your name at a routine traffic stop months or even years later can arrest you on the spot.

In civil cases, the judge may instead issue a writ of body attachment. The U.S. Marshals Service describes this as a court order directing a marshal to bring a person found in civil contempt before the court.⁶ The practical effect for you is the same: an arrest and a trip to court.

Grand Jury Subpoenas Are a Different Level

If the subpoena came from a grand jury, the stakes are higher and the court’s patience is shorter. Grand juries investigate potential criminal activity and their subpoena power is broad. Unjustified failure to comply can result in civil contempt, criminal contempt, or both. Under the recalcitrant witness statute, a judge can confine you for the remaining life of the grand jury term, including extensions, up to the 18-month ceiling.¹ If a successor grand jury renews the subpoena after the first term ends, the coercive pressure can effectively start over.

Ignoring a grand jury subpoena also signals to prosecutors that you may be obstructing the investigation. Even if you were subpoenaed only as a witness, defiance can change how the government sees you.

Reasons a Court Will Accept for Not Appearing

Not every failure to appear is willful defiance, and courts recognize several legitimate defenses. The common thread: you have to raise the issue with the court or the issuing attorney before the compliance date passes. Deciding on your own that the subpoena is bad and staying home is the path to contempt.

The Subpoena Was Not Properly Served

A subpoena only binds you if it was properly delivered. Under the federal rules, service must be made by someone at least 18 years old who is not a party to the case, and the server must deliver a copy to you personally. If the subpoena requires your attendance, the server must also tender one day’s witness attendance fee plus mileage at the time of service.⁵ A copy left with a roommate, dropped in the mail without follow-up, or handed over without the required fees may be defectively served, and a defectively served subpoena is not enforceable.

You Weren’t Given Reasonable Time

Federal rules require that a subpoena allow a reasonable time to comply. A subpoena received yesterday for a hearing tomorrow, where travel alone takes two days, is the kind of unreasonable demand a court will quash.⁵

Undue Burden

A subpoena that imposes an unreasonable burden on you — financial, logistical, or physical — must be quashed or modified on a timely motion.⁵ In federal civil cases, this includes a trial or deposition subpoena that would require you to travel beyond 100 miles from where you live, work, or regularly do business. In some administrative proceedings, anyone living more than 100 miles from the hearing location can ask the judge to be excused entirely.⁷ The party that issued the subpoena bears responsibility for avoiding undue burden and can be sanctioned, including paying your lost earnings and attorney’s fees, for failing to do so.

Medical Emergency

A genuine medical emergency that makes it physically impossible to appear is recognized, but the burden is on you to prove it. Expect the court to want documentation such as hospital records or a physician’s statement confirming you could not travel. A vague claim of feeling unwell will not do. The condition has to be serious enough that compliance was impossible, not merely inconvenient.

Fifth Amendment Privilege

If answering questions could expose you to criminal prosecution, the Fifth Amendment protects your right to refuse to answer. The privilege applies in any proceeding where testimony is legally required, including trials, depositions, and grand jury appearances. It covers not only answers that would directly support a conviction but also those that could provide a link in a chain of evidence.⁸

Here is the catch most people miss: you still have to show up and invoke the privilege. The Fifth Amendment doesn’t excuse you from appearing. It protects you from being forced to answer specific questions once you’re there. A witness who skips the hearing and later says they would have taken the Fifth has not properly asserted it. You are also not the sole judge of whether your fear of incrimination is valid; the court decides, though it must resolve doubts in your favor.⁸

The Right Way to Push Back: File a Motion

If you have a legal basis for not testifying, the proper response is a motion filed with the court. Two options are standard.

A motion to quash asks the court to invalidate the subpoena entirely. Grounds include improper service, excessive travel, undue burden, privileged information, or insufficient time to comply. In federal criminal cases, the court can quash or modify a subpoena if compliance would be unreasonable or oppressive.⁹

A motion for a protective order asks the court to narrow the subpoena rather than kill it, for example by limiting the topics you can be questioned about or shielding confidential information from disclosure.⁵

Both motions must be filed before your scheduled appearance. The federal rules only require that the motion be timely without specifying days, but waiting until the last moment signals bad faith and gives the court less reason to be sympathetic. Filing suspends your obligation to comply while the court decides.

If It’s Just a Scheduling Conflict, Call First

Not every problem requires a motion. If you have a real scheduling conflict — a medical procedure, a work obligation, pre-booked travel — your first step is to contact the attorney or party whose name appears on the subpoena. Attorneys reschedule witness appearances all the time. Most would rather adjust the date than deal with a no-show.

The attorney may agree to take your testimony by deposition on a different date, arrange a video appearance, or move the court date. Put every communication in writing. An email confirming a rescheduled date protects you if there’s any later dispute about whether you cooperated.

You Are Entitled to Witness Fees

Appearing as a witness is not entirely at your own expense. Federal law entitles witnesses to an attendance fee of $40 per day, which also covers travel time to and from the courthouse.¹⁰ If you drive your own vehicle, you’re reimbursed at the federal mileage rate set by the General Services Administration. State courts set their own fees, generally in a range of about $5 to $50 per day.

In federal civil cases, the party serving the subpoena must tender one day’s attendance fee and mileage at the time of service.⁵ In federal criminal cases, the same tender is required unless the subpoena was issued on behalf of the United States.⁹ The failure to tender those fees at service can itself be a ground to challenge the subpoena’s validity.
