A juror is a regular citizen chosen to help decide whether someone accused of a crime is guilty or not guilty, or to settle disagreements in civil court cases. When you become a juror, you sit with other jurors (often 12 people) in a jury box and listen carefully to all the evidence presented during a trial. You hear witnesses testify, examine evidence, and listen to lawyers from both sides explain their arguments.

After the trial ends, jurors meet privately in a room called the jury room to discuss everything they heard and saw. They must work together to reach a verdict: a decision about what really happened and what the law requires. In many criminal trials, jurors must agree unanimously (everyone votes the same way) to convict someone of a crime. This is a serious responsibility, because their decision affects real people's lives.

Serving as a juror is considered both a duty and an honor in many democracies around the world, including the United States, the United Kingdom, Canada, and Australia. The system works because jurors bring common sense and community values to legal decisions, rather than leaving everything to judges alone. Adults may receive jury duty notices in the mail, summoning them to court where they might be selected to serve.
