The length of jury duty depends on the type of case and whether you are selected

Jury duty can last anywhere from one day to several weeks, depending on what kind of case you are called for and whether you end up on the jury. If you show up for jury selection and are not chosen, you may be done the same day. If you are selected for a trial, you will serve for the length of that trial — which could be a few days for a small civil case or several weeks for a complex criminal case.

The initial summons itself is not jury duty. It is a notice telling you to appear at a specific courthouse on a specific date. That appearance day — called voir dire or jury selection — typically lasts a few hours to a full day. The actual service begins only if you are chosen to sit on a jury.

Key Takeaways

  • Jury selection (voir dire) usually takes a few hours to one full day, and most people who show up are dismissed without serving on a trial.
  • If you are selected, trial length varies widely: small civil cases may last 2 to 5 days, while criminal trials can run 2 to 4 weeks or longer.
  • You must attend every day of the trial once you are sworn in; missing court without permission can result in a contempt charge.
  • Some courts allow one-day or one-trial service, meaning you are dismissed after that single day or trial ends, even if you were selected.
  • Jury duty pay is set by the court and typically ranges from nothing on day one to $15 to $50 per day after that, depending on your state and county.

What happens on your first day — jury selection

When you arrive at the courthouse on the date listed in your summons, you will check in and wait in a jury assembly room with other potential jurors. The court will call groups of people into a courtroom for voir dire, the process of questioning potential jurors to see if they are impartial and suitable for the case.

Voir dire can take anywhere from 30 minutes to several hours, depending on the complexity of the case. The judge and the attorneys for both sides will ask you questions about your background, any biases you might have, and whether you can be fair. After questioning, the attorneys use their challenges to remove jurors they believe cannot be impartial. If you are not selected, you are dismissed — sometimes the same day, sometimes after waiting to see if another trial needs jurors.

If you are selected and sworn in, jury duty officially begins. You will be told when to return the next day and what time court starts.

How long a trial actually lasts

Trial length depends entirely on the case. A straightforward civil case — such as a contract dispute or a car accident claim — might take 2 to 5 days. The plaintiff presents evidence, the defendant responds, and closing arguments happen. You deliberate and reach a verdict.

Criminal trials take longer. A misdemeanor trial (a less serious crime) might last 3 to 5 days. A felony trial (a serious crime) can run 1 to 4 weeks or more. Complex cases with multiple defendants, informed witnesses, or large amounts of evidence can stretch to several months, though this is uncommon.

You do not know the trial length when you show up for jury selection. The court may give you an estimate, but trials often run longer than expected because of delays, unexpected motions, or slower-than-anticipated testimony.

One-day and one-trial jury service

Many courts now offer one-day or one-trial service. Under this system, if you are not selected for a trial on your first day, you are done — you do not have to return. If you are selected and serve on a trial, you are dismissed when that trial ends, even if the court needs jurors for other cases.

Not all courts use this system. Some courts may call you back for additional trials if you are not selected the first time, or may require you to serve on multiple trials before you are released. Check your summons or the court's website to see what system your courthouse uses.

What you must do once you are sworn in

Once you take the oath and become a juror, you are legally required to attend every day of the trial. Court typically runs Monday through Friday, 9 a.m. to 5 p.m., with a lunch break. Some courts have shorter hours or different schedules — your judge will tell you the exact times.

If you miss a day without permission, the judge can hold you in contempt of court, which can result in a fine or jail time. If you have a genuine emergency or hardship, tell the judge when ready. Some judges will excuse you; others will not. The safest approach is to assume you must be there every day until the trial ends and the judge dismisses you.

Jury deliberations happen after closing arguments. Deliberations can last anywhere from a few minutes to several days, depending on how complex the case is and how quickly jurors reach agreement. You must stay until a verdict is reached or the judge declares a mistrial.

How jury duty pay works

Most courts pay jurors, but the amount varies by state and county. Many courts pay nothing for the first day, then $15 to $50 per day after that. Some pay a flat rate per day. A few courts pay nothing at all.

Your employer is not required by federal law to pay you while you serve on jury duty, though some employers do. If your employer does not pay you, you receive only what the court pays. The court will tell you the pay rate when you arrive or in your summons.

Hardship and postponement

If serving on jury duty would cause genuine hardship — such as loss of income you cannot afford, care for a dependent with no alternative, or a medical condition — you can request postponement or dismissal. Send a letter to the court explaining your situation before your service date, or tell the judge during voir dire.

The judge decides whether your hardship is serious enough to excuse you. Inconvenience alone is usually not enough. If you are excused, the court may ask you to serve at a later date when your situation has changed.

Frequently Asked Questions

Can I be dismissed from jury duty after I am sworn in?

Once you are sworn in, the judge can dismiss you only for cause — meaning the judge finds a legal reason you cannot be impartial or must leave. You cannot straightforward ask to leave because the trial is taking longer than expected. If you have a genuine emergency, tell the judge when ready, but there is no may provide you will be excused.

What if my trial lasts longer than the court estimated?

Trials often run longer than expected. You are required to stay until the trial ends and you are dismissed by the judge. If the court gave you an estimate that turns out to be wrong, that does not change your obligation to serve.

Do I have to serve on jury duty if I was just called for selection?

No. Jury selection is not jury duty. If you show up for voir dire and are not selected, you are done. You only serve if you are chosen and sworn in as a juror.

Can my employer punish me for serving on jury duty?

Federal law prohibits employers from firing, threatening, or punishing an employee for jury service. If your employer retaliates against you, you may have a legal claim. Document any negative treatment and consider consulting an attorney.

What happens if I ignore my jury summons?

Ignoring a jury summons is contempt of court. The court can fine you, issue a warrant for your arrest, or order you to appear and explain why you did not show up. If you cannot serve, contact the court before your date and request postponement or dismissal.
