The timeline depends on the type of case, but most jurors serve between one day and two weeks

Jury duty length varies widely. A criminal misdemeanor trial might last three days. A civil lawsuit could run two weeks. Some jurors report for jury selection and go home the same day because attorneys reject them. Others sit through a month-long case. The court cannot tell you in advance how long you will serve because the length depends on how fast the trial moves, how many witnesses testify, and how long jury deliberations take — none of which are known when you receive your summons.

What you can control is understanding the different phases of jury service and what happens at each one. Knowing the structure helps you plan time off work and understand what the court will ask of you.

Key Takeaways

  • Jury selection (called voir dire) typically takes one to three days, though some cases finish selection in a few hours.
  • The trial itself — opening statements, witness testimony, and closing arguments — is the longest phase and varies from one day to several weeks depending on case complexity.
  • Jury deliberations can last anywhere from one hour to several days, and you cannot leave the jury room until a verdict is reached or the judge declares a mistrial.
  • You must report on your assigned date even if you think the case will be short; courts do not release jurors until the judge officially dismisses them.
  • Some courts allow you to request a different service date if the assigned date creates genuine hardship, but you must ask before your report date.

Jury selection: one to three days, sometimes less

When you arrive at the courthouse on your report date, you enter the jury selection phase, also called voir dire. The judge and attorneys question potential jurors to decide who will sit on the jury. This phase can take anywhere from a few hours to three days or longer, depending on how many jurors need to be questioned and how detailed the questioning is.

In a straightforward case — a traffic accident or a small theft — selection might finish in one morning. In a high-profile criminal case or a complex civil lawsuit, attorneys may spend days asking potential jurors about their backgrounds, biases, and beliefs. If you are rejected during selection, you are released and do not serve. If you are chosen, you move into the trial phase.

The trial phase: one day to several weeks

Once the jury is seated, the trial begins. The judge gives instructions, attorneys make opening statements, witnesses testify, evidence is presented, and attorneys make closing arguments. This is the longest and most unpredictable phase.

A straightforward criminal case — a shoplifting charge with one or two witnesses — might take one or two days. A car accident lawsuit with multiple witnesses and informed testimony might take a week. A felony case with many witnesses, complex evidence, or multiple defendants can run two to four weeks or longer. Medical malpractice cases, construction disputes, and other complex civil cases sometimes last a month or more.

The court cannot predict this length because it depends on how many witnesses testify, how long each testimony takes, how many documents or videos are introduced, and whether unexpected legal issues arise that require the judge to hold separate hearings. You must stay until the trial phase ends, even if it runs longer than expected.

Jury deliberations: one hour to several days

After closing arguments, the judge instructs the jury on the law, and jurors move to the jury room to discuss the case and reach a verdict. This phase is called deliberations. You cannot leave the jury room, speak to anyone outside the jury, or access phones or the internet during deliberations.

Some juries reach a verdict in an hour. Others deliberate for days. A straightforward case with clear evidence might produce quick agreement. A case with conflicting testimony or a close legal question might require lengthy discussion. If jurors cannot reach a unanimous verdict after a reasonable time, the judge may declare a mistrial, and you are released. If a verdict is reached, you are dismissed after the verdict is announced in court.

What happens if you cannot serve the full length

Courts understand that jury duty creates hardship. If your assigned report date falls during a time when serving would cause genuine hardship — a scheduled surgery, a non-refundable trip, a critical work important date — you can request to postpone your service to a different date. You must make this request before your report date, usually by calling the court or responding to the summons with a written request.

The court may grant your request and assign you a new date, or it may deny the request if the court is short on jurors. Once you report and are seated on a jury, you cannot leave early except in extraordinary circumstances — a serious illness or a death in your family. The judge has discretion to release you, but this is rare.

How courts estimate service length

When you receive your summons, it may include an estimate of how long service will take. This estimate is based on the cases scheduled for that week or month, but it is not a may provide. Cases settle before trial, which shortens the list. Cases take longer than expected, which extends service. Some courts post case information online or allow you to call a jury hotline to learn whether your report date is still needed.

If you are called for a specific trial — rather than reporting to a general jury pool — the court can give you a more accurate estimate because the case is already assigned. If you are reporting to a general pool, the estimate is rougher because the court does not yet know which cases will actually go to trial.

Frequently Asked Questions

Can I leave jury duty early if I have already missed work?

No. Once you are seated on a jury, you must stay through the verdict or mistrial, regardless of work or personal losses. If you have a genuine emergency — a medical crisis or a death in your family — you can ask the judge to release you, but this is uncommon. The time to request postponement is before you report, not after you are seated.

What if the trial is taking longer than the court estimated?

You must continue serving. Courts cannot always predict how long a trial will take. Witness testimony may take longer than expected, or legal issues may arise that require extra time. You are required to stay until the judge dismisses you, which happens after the verdict is announced or a mistrial is declared.

Do I have to serve if I am already on another jury?

No. If you are currently serving on a jury, you can request postponement of a new summons. Contact the court and explain that you are already serving. The court will typically reschedule you for a later date.

What if I am selected for a jury but the case settles before trial starts?

You are released when ready. Cases settle frequently, especially after jury selection is complete. When this happens, the judge thanks you and dismisses you. You have fulfilled your duty, even though no trial occurred.

Can the court force me to stay past the end of the business day?

Yes, if deliberations are ongoing. If the jury is close to reaching a verdict, the judge may keep jurors in the jury room past normal hours. In rare cases involving serious crimes or complex cases, deliberations have continued into the evening. The court provides breaks and meals, but you cannot leave until a verdict is reached or the judge ends deliberations for the day.
