Jury duty is a legal obligation to serve on a jury if you are summoned by a court

When you receive a jury summons, the court is asking you to show up on a specific date to potentially sit on a jury for a trial. A jury is a group of ordinary people — usually between 6 and 12 — who listen to evidence in a case and decide the outcome. If you are selected, you will hear arguments from both sides, review evidence, and vote on whether the defendant is guilty (in criminal cases) or liable (in civil cases). Jury duty is not optional; it is a civic responsibility backed by law, and ignoring a summons can result in fines or other penalties.

The court sends summonses to people randomly, usually pulling names from voter registration lists, driver's license records, or tax rolls. You do not apply for jury duty — the court chooses you. Once summoned, you attend a process called voir dire, where lawyers and the judge ask you questions to determine if you can be fair and impartial. If selected, you serve for the length of the trial, which can range from one day to several weeks depending on the case.

Key Takeaways

  • Jury duty is mandatory when you receive a summons, and ignoring it can result in fines or legal consequences.
  • The court selects jurors randomly from lists of registered voters and licensed drivers, not from people who volunteer.
  • You will attend voir dire, a questioning process where lawyers determine whether you can be impartial before the trial begins.
  • Jury service typically lasts the length of the trial, which varies from one day to several weeks, and most employers are required by law to allow you time off.
  • You can request a postponement or explain hardship to the court, but you cannot simply ignore the summons without consequences.

How you are selected for jury duty

The court clerk's office maintains lists of potential jurors drawn from public records. In most states, these lists come from voter registration rolls, driver's license databases, or both. The court uses a random selection process — similar to a lottery — to pull names and send out summonses. You have no control over whether your name is drawn, and you cannot volunteer to serve.

The summons itself is a formal document that tells you the date, time, and location to report. It will also explain what to bring (usually a photo ID and proof of residence) and what to expect. Read the summons carefully, because it contains instructions specific to your court. Some courts require you to call a phone line or check a website the day before to confirm whether you need to show up, since not all summoned jurors are needed for every trial.

What happens during voir dire

Voir dire is the questioning process that happens before a trial starts. You will sit in a courtroom with other summoned jurors while the judge and lawyers ask questions about your background, beliefs, and ability to be fair. The questions are designed to uncover bias — for example, a lawyer might ask if you have ever been in a car accident if the case involves a traffic collision, or if you have family in law enforcement if the case involves police conduct.

During voir dire, either the prosecution or defense can ask the judge to dismiss you for cause, meaning they believe you cannot be impartial. You can also be dismissed through a peremptory challenge, which allows lawyers to remove a limited number of jurors without stating a reason. If you are not dismissed, you are seated on the jury and take an oath to be fair and follow the law.

Your responsibilities once you are seated

Once selected, you must attend every day of the trial. You will listen to opening statements from both sides, hear witness testimony, review physical evidence, and listen to closing arguments. You are expected to keep an open mind, avoid discussing the case with anyone (including other jurors) until deliberations begin, and follow the judge's instructions about the law.

After all evidence is presented, you and the other jurors move to a private room called the jury room to deliberate. Deliberation means discussing the evidence and voting on the verdict. In criminal cases, the verdict must usually be unanimous (all jurors agree), though some states allow non-unanimous verdicts in certain situations. In civil cases, the standard varies by state but often requires a supermajority or unanimous vote. You cannot leave the jury room until a verdict is reached or the judge declares a mistrial.

How long jury duty lasts

The length of jury service depends entirely on the trial. Some trials last only one day; others can last weeks or even months. During jury selection (voir dire), you may wait several hours or even a full day before learning whether you are selected. If you are not chosen, you are typically dismissed and do not need to return. If you are selected, you must serve for the entire trial plus deliberations, which can extend the timeline unpredictably.

Most employers are required by law to allow employees time off for jury duty without penalty. However, the amount of pay you receive during jury service varies. Some employers continue your full salary; others pay nothing. The court may also provide a small daily stipend (usually $15 to $50 per day, depending on the state and court), though this rarely covers lost wages. Check with your employer about their jury duty policy before your service date.

Requesting postponement or explaining hardship

If the summons date creates a genuine hardship — such as a medical procedure you cannot reschedule, a critical work deadline, or caregiving responsibilities — you can request a postponement. The court will ask you to explain the hardship in writing or by phone. Common reasons the court accepts include active medical treatment, pre-booked travel, or being the sole caregiver for a dependent. The court may postpone your service to a later date rather than dismissing you entirely.

Simply being busy or inconvenienced is not usually grounds for postponement. The court recognizes that jury duty is disruptive, but it is considered a shared civic duty. If you request a postponement and the court denies it, you must still appear on the assigned date. If you do not show up without permission, the court can issue a bench warrant, fine you, or hold you in contempt.

What happens if you ignore a jury summons

Ignoring a jury summons is treated as contempt of court. The penalties vary by state and court but can include fines ranging from $100 to $1,000 or more, and in some cases jail time. The court may also issue a new summons with a warning, or it may pursue legal action immediately. A single missed summons can escalate quickly, so if you cannot attend, contact the court before the date to request a postponement or explain your situation.

If you move and do not receive the summons, or if the summons is sent to an old address, you are still responsible for knowing about it. Some courts maintain records of people who repeatedly ignore summonses and may pursue more aggressive enforcement. The safest approach is to respond to any court document you receive, even if you need to request a postponement.

Frequently Asked Questions

Can I be fired from my job for serving on a jury?

No. Federal law and most state laws prohibit employers from firing, threatening, or penalizing an employee for jury service. If your employer retaliates against you for serving, you may have grounds for a legal claim. However, employers are not required to pay you during jury service unless state law or company policy says otherwise.

What if I have a medical condition or disability that makes jury service difficult?

Contact the court before your service date and explain your condition. The court may postpone your service, excuse you, or make accommodations such as allowing you to sit in a specific location or take breaks. Bring documentation from a doctor if possible. The court takes accessibility seriously, but you must communicate your needs in advance.

Do I have to answer all the questions during voir dire?

Yes. Voir dire questions are asked under oath, and lying during this process can result in perjury charges. You must answer truthfully, even if the answer might get you dismissed. Lawyers and judges can tell when someone is not being honest, and false answers undermine the fairness of the trial.

What if I cannot afford to miss work for jury duty?

Many employers continue your pay during jury service, so check your employee handbook or ask your HR department first. If your employer does not pay, the court may provide a small daily stipend. Some courts also allow you to request a postponement if the timing creates severe financial hardship. Explain your situation to the court in writing before your service date.

Can I be excused from jury duty permanently?

Permanent excusal is rare and usually granted only to people over a certain age (varies by state, often 70 or older), people with severe medical conditions, or people with caregiving responsibilities that cannot be delegated. You must request this in writing with supporting documentation. Most people are expected to serve at least once in their lifetime.
