Jury duty length depends on the type of case, but most trials last between three days and two weeks
The time you spend on jury duty breaks into two separate periods: the time to select a jury (called voir dire), which usually takes one to three days, and the trial itself, which varies widely. A simple civil case might wrap in three to five days. A criminal trial can run two weeks or longer. Some cases settle or resolve before trial starts, which means you show up, sit through jury selection, and go home—sometimes the same day.
Your court will tell you the expected length when you receive your summons or when you call in. That estimate is not a may provide, but it gives you a real starting point for planning. If a trial runs longer than expected, the judge can extend it, and jurors are required to stay.
Key Takeaways
- Jury selection typically takes one to three days, and you may be dismissed during this phase without serving on a trial.
- Once seated, you will serve for the length of the trial, which ranges from a few days for simple cases to several weeks for complex ones.
- The court provides the expected trial length in your summons or when you call the jury hotline before your service date.
- If you are dismissed after selection, your service is complete; if you are seated, you must stay until the verdict is delivered.
- Some courts allow you to request a postponement to a different time if jury duty conflicts with work or personal obligations.
What happens during jury selection and how long it takes
Jury selection is the process where attorneys and the judge question potential jurors to decide who will sit on the case. This is called voir dire. In a straightforward case, this might take a single morning. In a high-profile or complex case, it can stretch across several days.
During selection, you answer questions about your background, any biases you might have, and whether you can be fair. Attorneys can dismiss jurors they believe will not favor their side. The judge can dismiss jurors for cause—meaning a real legal reason, like a conflict of interest. Once enough jurors are seated (usually 12, plus alternates), selection ends and the trial begins.
If you are dismissed during selection, you are done. Your jury duty is over. If you are seated, you move into the trial phase, and you stay until a verdict is reached.
Trial length varies by case type and complexity
A civil case—a dispute between two parties over money or property—often takes three to ten days. These cases tend to involve fewer witnesses and simpler evidence than criminal cases.
A criminal case can run anywhere from a few days for a straightforward misdemeanor to several weeks or months for a felony with multiple defendants or extensive evidence. A murder trial or a case involving fraud can easily take four to eight weeks or longer.
The court's summons or jury hotline will give you an estimate. Ask specifically whether the case is civil or criminal, and how many days the court expects the trial to last. That number is based on how many witnesses the attorneys plan to call and how much evidence needs to be presented.
What you do each day during a trial
Once the trial starts, you report to the courthouse each morning at a set time. You sit in the jury box and listen to opening statements from both sides, witness testimony, evidence presentations, and closing arguments. You take notes if the judge allows it. You do not speak or ask questions during the trial.
Court days typically run from 9 a.m. to 4 or 5 p.m., with a lunch break and sometimes a mid-morning break. Some courts release jurors early on certain days. The judge controls the schedule and can extend hours if the trial is running behind.
Once all evidence is presented and closing arguments are finished, the judge gives you instructions on the law. You then go to the jury room with the other jurors to discuss the case and reach a verdict. This deliberation can take anywhere from an hour to several days, depending on how complex the case is and how much the jurors disagree.
Deliberation time is unpredictable and can extend your service
After the trial ends, you move into deliberation—the time jurors spend discussing the case and voting on a verdict. This is the hardest part to predict. A straightforward case might take two hours. A complicated case with multiple charges or conflicting evidence can take days.
You cannot leave the jury room during deliberation unless the judge excuses you. If jurors cannot reach a unanimous verdict after a reasonable time, the judge may declare a mistrial, and you are released. If you do reach a verdict, you announce it in court, and your service is complete.
Requesting a postponement if jury duty conflicts with your schedule
If your summons arrives and jury duty falls during a time you cannot serve—because of a planned surgery, a non-refundable vacation, or a critical work deadline—you can request a postponement. Contact the court listed on your summons and explain your conflict. Many courts will move your service to a later date.
The key is to request the postponement before your service date. Waiting until you arrive at the courthouse makes it much harder to reschedule. Some courts have online portals where you can request a postponement; others require a phone call or a letter.
Hardship—like being the sole caregiver for a child or an elderly parent—is a reason courts consider for excusal, though they do not always grant it. Requesting a postponement is usually easier than requesting an excusal.
What happens if a trial runs longer than expected
If the case takes longer than the court estimated, you stay. The judge can extend court hours, add weekend sessions, or continue the trial into the following week. You are required to serve for the duration of the trial and deliberation.
If the extension creates a genuine hardship—like you are the only person caring for a sick relative—tell the judge. The judge has discretion to excuse you, though this is rare once a trial has started. It is better to raise scheduling conflicts before your service date.
Frequently Asked Questions
Can I leave early if the trial is taking longer than expected?
No. Once you are seated on a jury, you must stay until the verdict is delivered. The judge can excuse you only in rare circumstances involving genuine hardship. If you have a serious conflict, tell the judge immediately.
What if I get sick during jury duty?
Tell the judge or a court officer right away. If you are too ill to serve, the judge may excuse you and seat an alternate juror. Do not try to hide an illness or continue serving if you are unable to focus on the case.
Do I have to serve on a jury if I work full-time?
Yes. Employers are required by law not to fire or punish you for serving jury duty. Some employers pay you during jury service; others do not. Check your employee handbook or ask your HR department about your company's policy.
What if I am selected for a trial but the case settles before it starts?
If the case settles or is dismissed after you are seated but before testimony begins, you are released and your service is complete. This happens occasionally and means you spent time on selection but not on the actual trial.
How do I know how long my specific trial will last?
Call the jury hotline number on your summons a day or two before your service date, or ask the court clerk when you arrive. They will give you an estimate based on the number of witnesses and the complexity of the case.
