Jury duty is a legal obligation to show up when a court summons you, listen to evidence in a case, and help decide the outcome by voting with other jurors

When you receive a jury summons, the court is ordering you to appear on a specific date at a specific time. You are not being accused of anything. Instead, the court needs citizens to sit in a jury box, hear both sides of a case, and vote on whether the defendant is guilty (in criminal cases) or liable (in civil cases). If you are selected to serve on a jury, you become part of the judicial system itself — you are not a lawyer, judge, or court employee, but your vote counts equally with the other jurors' votes.

Jury duty exists because the U.S. Constitution guarantees people the right to be judged by a jury of their peers. That means ordinary people like you, not just government officials. Without jurors, courts could not function. The process starts when you receive a summons in the mail, continues through jury selection (called voir dire), and ends when you either serve on a jury or are dismissed.

Key Takeaways

  • A jury summons is a court order requiring you to appear on a set date; ignoring it can result in fines or jail time.
  • Jury selection happens first — lawyers and the judge ask questions to decide who will actually sit on the jury, and many people are dismissed at this stage.
  • If you are chosen, you listen to evidence, hear arguments from both sides, and vote on the verdict with other jurors in a private room.
  • Jury duty typically lasts from one day to several weeks depending on the case, and you receive a small daily payment from the court.
  • You can request postponement or be excused for genuine hardship, but you must contact the court in writing — ignoring the summons is not an option.

The difference between being summoned and being selected

Receiving a jury summons does not mean you will serve on a jury. The summons is an order to show up; selection happens after you arrive. On the day you report, you and dozens or hundreds of other people sit in a waiting area called the jury pool. The court then calls groups of potential jurors into a courtroom for a process called voir dire, where lawyers from both sides and the judge ask you questions about your background, beliefs, and whether you can be fair.

During voir dire, either lawyer can ask the judge to dismiss you "for cause" — meaning they believe you cannot be impartial. For example, if you know the defendant personally or have a strong bias about the type of case, you can be dismissed for cause. Lawyers also have a limited number of peremptory challenges, which let them dismiss jurors without giving a reason, though they cannot use these to discriminate based on race, gender, or other protected characteristics. After this process, the remaining people become the jury.

What you actually do during jury service

Once selected, you sit in the jury box during the trial. The judge explains the law, lawyers present evidence and arguments, and witnesses testify. You listen and take notes. You cannot talk to anyone about the case — not other jurors, not people outside the court, not even your family — until the trial ends and you are dismissed.

When both sides finish presenting their cases, the judge gives you written instructions about the law and what you must decide. You and the other jurors then go into a private room called the jury room to discuss the case and vote. In criminal cases, you must usually reach unanimity — all jurors must agree on guilty or not guilty. In civil cases, the requirement varies by state; some require unanimity, others allow a majority vote. If you cannot reach agreement, it is called a hung jury, and the judge may declare a mistrial.

How long jury duty lasts

The length of jury duty depends entirely on the case. Some trials last one day. Others last weeks or months. When you report for jury duty, the court tells you how long you might be needed. If you are dismissed during voir dire, you may be done in a few hours. If you are selected for a trial, you stay until the verdict is reached and you are released by the judge.

Many courts use a "one day or one trial" system, meaning you either serve for one day in the jury pool or you stay for the entire trial you are assigned to, whichever comes first. A few courts require longer service — sometimes a month or more — but this is less common. You receive payment for each day you serve, though the amount is small (often $15 to $50 per day depending on your state and county).

Your rights and responsibilities as a juror

You have the right to understand the case. If you do not understand something the judge or a lawyer said, you can ask for clarification. You have the right to take notes during the trial in most courts. You also have the right to request time off work — employers cannot legally punish you for serving jury duty, though they do not have to pay you while you are gone.

Your responsibility is to listen fairly to all evidence, follow the judge's instructions about the law, and vote your honest opinion. You cannot do your own research, visit the crime scene, or look up information about the case online. You cannot discuss the case with anyone until the trial ends. You must show up on time each day and stay until you are dismissed. If you are selected for a jury, you are bound by oath to perform these duties.

What happens if you ignore a jury summons

Ignoring a jury summons is not a minor matter. The court can hold you in contempt, which can result in fines (often $100 to $1,000 or more) or jail time. Some courts issue a second summons; if you ignore that, the consequences increase. A few states have suspended driver's licenses or professional licenses for people who repeatedly ignore jury summons.

If you genuinely cannot serve, you must contact the court in writing or by phone before the date on your summons. Explain your hardship — serious illness, financial crisis, caregiving responsibilities, or a previously scheduled commitment you cannot change. The court may postpone your service to a later date or excuse you entirely. But you must reach out; silence is treated as defiance.

Criminal versus civil jury duty

In a criminal case, the defendant is accused of breaking the law. The prosecution (government) must prove guilt "beyond a reasonable doubt" — a very high standard. You vote guilty or not guilty. If you vote guilty, the defendant may go to prison. If you vote not guilty, they are released and cannot be tried again for the same crime.

In a civil case, one person or company is suing another for money or some other remedy. The standard is lower: the plaintiff must prove their case by a "preponderance of the evidence" — meaning it is more likely true than not. You vote on whether the defendant is liable (responsible) and, if so, how much money they owe. Civil cases are about disputes, not criminal punishment.

Frequently Asked Questions

Can I be fired from my job for serving jury duty?

No. Federal law and most state laws prohibit employers from firing, threatening, or punishing you for jury service. However, employers do not have to pay you while you are gone. If you lose income because of jury duty, you can discuss this with the judge; some courts offer hardship deferrals for people with severe financial need.

What if I have a medical condition or disability?

Contact the court before your summons date and explain your condition. Many courts can accommodate disabilities — providing accessible seating, allowing service animals, or permitting you to sit in a specific location. If serving is truly impossible, the court may excuse you. Always communicate with the court rather than simply not showing up.

Do I have to answer all the questions during jury selection?

Yes. During voir dire, you must answer questions honestly. Lying to avoid jury duty is perjury, a crime. If you have a genuine reason you cannot be fair — such as a personal connection to the defendant or a strong bias — say so. Judges and lawyers expect honest answers and will dismiss you if there is a real conflict.

What if the jury disagrees and cannot reach a verdict?

If you cannot unanimously agree (in criminal cases) or reach the required majority (in civil cases), you report this to the judge. The judge may send you back to deliberate further, or may declare a mistrial. In a mistrial, the case may be retried with a new jury, dismissed, or settled. You are not responsible for a hung jury — you did your job by voting your honest opinion.

Can I request to be excused from jury duty permanently?

No, but you can request postponement. Most courts allow you to defer service to a later date if the timing is bad. Some courts excuse people over a certain age (often 70 or 75) or those with severe hardship. Each court has different rules, so check your summons or contact the court directly to learn what options exist in your jurisdiction.
