If you ignore a subpoena, a judge can hold you in contempt of court, fine you, and in serious cases issue a bench warrant for your arrest. A subpoena carries the force of a court order, and you’re legally required to comply once it’s properly served on you. That’s the short answer to what happens if you ignore a subpoena. The longer answer depends on who issued it, whether you’re a party to the case, and whether the subpoena itself is actually valid — because a subpoena that was served the wrong way, demands too much, or reaches too far can be challenged and thrown out.
The Penalties for Noncompliance
The primary consequence is contempt of court. Federal courts have broad authority to punish contempt by fine, imprisonment, or both when someone disobeys a lawful court order.1Office of the Law Revision Counsel. 18 USC 401 – Power of Court A judge will typically hold a hearing where you can explain your failure to comply before imposing a penalty.
For a specific category of federal criminal contempt, the penalty caps at six months in jail and a fine of up to $1,000 payable to the government.2Office of the Law Revision Counsel. 18 USC 402 – Contempts Constituting Crimes Those caps don’t apply everywhere. Courts handling civil contempt aimed at forcing compliance can impose escalating daily fines or open-ended jail time that lasts until you do what the subpoena says. A judge can also order you to pay the other side’s attorney’s fees caused by your failure to show.
Extra Consequences If You Are a Party
The stakes rise sharply if you’re not just a witness but an actual party to the lawsuit, or a company officer or designated representative of a party. The court can treat contested facts as established against you, bar you from presenting certain evidence or defenses, strike your pleadings, or enter a default judgment that hands the win to the other side. On top of those sanctions, the court must order the non-compliant party or their attorney to pay the reasonable expenses caused by the failure, including attorney’s fees, unless the failure was substantially justified.3Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
Grand Jury Subpoenas Are Worse
If the subpoena comes from a grand jury in a federal criminal investigation, the rules are stricter and the consequences more immediate. Grand jury subpoenas are governed by Federal Rule of Criminal Procedure 17, not the civil rules, and they can be served anywhere in the United States. The usual 100-mile geographic limit does not apply.4U.S. Department of Justice. Justice Manual 9-11.000 – Grand Jury
Witnesses who refuse to answer questions properly posed by a grand jury can be jailed until they comply, and that confinement can last for the entire life of the grand jury, which typically sits for 18 months and can be extended to 24.4U.S. Department of Justice. Justice Manual 9-11.000 – Grand Jury You keep your Fifth Amendment right against self-incrimination, but your ability to challenge on other grounds is narrower than in a civil case. If a grand jury subpoena lands, call a lawyer that day.
When You Can Push Back on the Subpoena Itself
A subpoena is not bulletproof. Federal Rule of Civil Procedure 45 lays out several situations in which a court must quash or modify one, and state rules follow a similar pattern.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Before you decide whether to comply, look at how it was served and what it demands.
Improper Service
A federal subpoena must be personally delivered by someone who is at least 18 and not a party to the case.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena If yours was left with a family member, mailed to you, or handed over by one of the attorneys in the case, service may be defective.
No Witness Fee Was Tendered
Most people never hear this: in federal court, anyone who serves you with a subpoena for your attendance must also hand you a check for one day’s witness fee and mileage at the time of service.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Skip that step and the subpoena may be defective. Courts have quashed subpoenas where the fee wasn’t tendered at service, treating the omission as more than a technicality.
The federal witness fee is $40 per day of attendance, including travel days.6Office of the Law Revision Counsel. 28 USC 1821 – Per Diem and Mileage Generally; Subsistence Mileage reimbursement for 2026 is 72.5 cents per mile, round trip from your home to the place where you must appear.7GSA. GSA Bulletin FTR 26-02 Parking, tolls, and similar travel costs may also be reimbursable. The one exception: when the federal government issues the subpoena, it does not have to tender fees at service.
Undue Burden
The party issuing a subpoena must take reasonable steps to avoid imposing undue burden or expense on you.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena A demand for a massive volume of documents on an unreasonably short timeline, or one that would cost you thousands of dollars to organize and copy, is exactly what courts will modify or quash. The subpoena also has to give you a reasonable amount of time to comply.
Geographic Limits
A subpoena can only compel you to attend a trial, hearing, or deposition within 100 miles of where you live, work, or regularly do business in person.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Try to drag a witness across the country for a deposition and the subpoena exceeds its geographic reach, and a court must quash it. A narrow exception lets a party or a party’s officer be required to attend trial anywhere within their home state, if it wouldn’t cause substantial expense.8United States Courts. AO 88B – Subpoena to Produce Documents, Information, or Objects or to Permit Inspection of Premises in a Civil Action
Privileged or Incriminating Material
A court must quash a subpoena that seeks privileged or otherwise protected material when no exception or waiver applies.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Attorney-client communications and doctor-patient confidentiality are the common ones. The Fifth Amendment separately protects you from being compelled to give testimony that could incriminate you in a criminal matter, and the Supreme Court has read that protection broadly enough to cover any response that could furnish even a link in the chain of evidence needed for prosecution.9Congress.gov. Constitution Annotated – Amdt5.4.3 General Protections Against Self-Incrimination Doctrine and Practice
How to Formally Challenge It
Spotting a defect doesn’t help unless you raise it the right way and on time. The mechanism depends on what the subpoena demands.
Motion to Quash
To challenge a subpoena for testimony, or one that demands both testimony and documents, file a motion to quash with the court in the district where compliance is required. The motion must be in writing, lay out your specific legal grounds, and be filed on a timely basis, which courts generally read to mean before the compliance date on the subpoena.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Serve a copy on the attorney who issued the subpoena.
One common misconception: filing a motion to quash does not automatically freeze your obligation to comply. Most judges won’t hold you in contempt while a motion is pending, but there’s no rule that says the subpoena is stayed the moment you file. If the compliance date is close, ask the court for an explicit stay, or get the issuing attorney to agree in writing to postpone the deadline while the motion is decided.
Written Objection for Document-Only Subpoenas
For subpoenas that ask only for documents, Rule 45 offers a lighter alternative. Serve a written objection on the attorney who issued the subpoena, before the compliance deadline or within 14 days of service, whichever comes first.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Once you object, the burden shifts: the requesting party has to go to court and obtain an order compelling production before you have to hand anything over. That gives you real breathing room without the cost of a formal motion.
When You Just Can’t Make the Date
Not every conflict is a legal fight. A medical procedure, a booked trip, or a hard work obligation can make the scheduled date impossible. The practical move is to call the attorney whose name is on the subpoena, explain the conflict, and propose an alternative date.
Attorneys reschedule depositions and hearing appearances all the time. Most would rather accommodate a reasonable request than file a motion to compel and wait for a hearing. Get any agreement in writing. An email confirming the new date protects you if there’s later a dispute about whether you had permission to skip the original one.
You may also be able to skip a personal appearance for records requests. If the subpoena demands business records rather than personal testimony, federal law lets you submit the records with an unsworn written declaration under penalty of perjury instead of traveling to court to authenticate them on the stand.10Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury It’s especially useful for records custodians at businesses and healthcare providers. The declaration has to follow a specific format and be signed and dated.
Your Job Is Protected
People worry that complying with a subpoena will cost them their job. Federal civilian employees are entitled to paid court leave when summoned as a witness in a proceeding where a government entity is a party.11U.S. Office of Personnel Management. Fact Sheet – Court Leave Private-sector employees don’t have the same federal guarantee of paid leave, but many states require employers to allow time off for court appearances and prohibit retaliation for complying with a subpoena.
On the criminal side, federal law makes it a serious offense to retaliate against someone for testifying or attending an official proceeding. Interfering with a person’s employment because they gave truthful information to law enforcement about a federal offense is punishable by up to 10 years in prison.12Office of the Law Revision Counsel. 18 USC 1513 – Retaliating Against a Witness, Victim, or an Informant If your employer threatens your job because you’ve been subpoenaed, document the threat and talk to a lawyer. You likely have protection under federal law, state law, or both.
