A witness who has been subpoenaed should plan on spending most of the day at the courthouse, even though actual time on the witness stand usually runs between 30 minutes and a few hours. So the honest answer to how long a witness stays in court is: your testimony is short, but your day is long. The gap between those two numbers surprises most first-time witnesses, and understanding where the extra hours go is the difference between a frustrating day and a manageable one.
Time on the Stand vs. Time at the Courthouse
Testimony itself is usually the shortest part of the day. A simple factual witness can be on and off the stand in about 30 minutes. A witness central to the dispute, or an expert, may spend several hours answering questions. The questioning moves through direct examination by the attorney who called you, cross-examination by the opposing attorney, and sometimes shorter re-direct and re-cross rounds to clean up loose ends.1U.S. Department of Justice. Tips for Testifying – Section: Being Sworn In as a Witness The judge controls the pace and can shut down repetitive or harassing questioning.2Legal Information Institute. Federal Rules of Evidence Rule 611
Everything around that testimony is what turns 30 minutes into a full day. You arrive early to clear security, check in with the attorney who subpoenaed you, and then wait. Court schedules shift without warning, so you may sit for hours before anyone calls your name.
Why the Wait Is So Long
Courts routinely keep witnesses separated from each other and out of the courtroom before they testify. This practice is called sequestration, and it exists to prevent one witness’s testimony from shaping another’s account. Either attorney can request it, or the judge can order it independently.3Legal Information Institute. Federal Rules of Evidence Rule 615 – Excluding Witnesses From the waiting area, you have no visibility into what is happening in the courtroom and no reliable estimate of when you will be called.
Several things stretch the wait. Every witness scheduled ahead of you adds time, and any of them can run longer than expected. Judges also pause proceedings for legal arguments, sidebar conferences, and juror issues. None of that is predictable from where you are sitting.
Ask to Be Placed On Call
One arrangement can shorten your day considerably. Some attorneys will agree to place you “on call,” meaning you can leave the courthouse and go about your day with the understanding that you’ll return within an hour or two of being notified. This isn’t guaranteed, and it depends on the attorney, the judge, and the shape of the case. But if you have work or family obligations, raise it with the attorney who subpoenaed you before the trial date. It can turn a wasted day into a few focused hours.
Excused or Subject to Recall
Finishing your testimony doesn’t automatically end your obligation. Listen closely to what the judge says as you step down.
If the judge says you are “excused,” your subpoena obligation is complete. You can leave and you won’t need to come back for that case. If the judge instead tells you that you are “subject to recall,” you can leave the building but must stay available to return for further questioning. That status can last days, and in a lengthy trial it can stretch into weeks. New evidence or a follow-up point from your testimony can bring you back. Before you book travel or commit to anything on the other side of your court date, ask the attorney who called you whether recall is realistic.
What to Bring and What to Expect at Security
Courthouse security works like airport security. You’ll walk through a metal detector, and any bags go through an X-ray machine. Weapons, pepper spray, and bladed items longer than about two and a half inches are prohibited in federal facilities.4National Archives. Items Prohibited From Federal Facilities – An ISC Standard
Phones and laptops are generally allowed in the building, but individual courts can restrict or ban electronics from specific courtrooms. Keep your phone silenced and out of sight once inside. Recording court proceedings is prohibited in virtually every courthouse.5Kansas Judicial Branch. Rule 1002 – Non-Media Use of an Electronic Device in a Court Facility Because you may wait for hours with no idea when you’ll be called, bring something to read, a phone charger, and a snack or two. Once you check in, you’ll be pointed to a witness waiting area where you’ll stay until someone comes to get you.
Geography and Travel
A subpoena is a court order that tells you when, where, and what time to appear. In federal court, a subpoena can require you to travel up to 100 miles from where you live or work, or anywhere within your home state if you are a party to the case or if attending trial wouldn’t cause substantial expense.6Legal Information Institute. Federal Rules of Civil Procedure Rule 45 The farther you travel, the more it matters to know whether you’ll be excused the same day or told to remain on call, because that answer decides whether you’re driving home that evening or looking for a hotel.
Don’t Just Skip It
Ignoring a subpoena is not an option. Federal courts can punish noncompliance as contempt through fines, imprisonment, or both.7Office of the Law Revision Counsel. 18 USC 401 – Power of Court If your appearance is genuinely a hardship, that gets addressed through the court in advance, not by failing to show up. Once you’re there, though, the long day is the real cost, and knowing how it will unfold is the best way to make it shorter.
