How long is jury service? Jurors who do not sit on a jury trial may serve for as little as 1–2 days. However, even if not needed for a trial, a juror may be asked to be available or on call for up to five days. Those who are selected to serve on a jury are required to serve on only one trial. The judge informs the jurors how long the trial is expected to last. Length of service on a grand jury may vary from two weeks to a month or more. For more information about service as a grand juror see the Unified Court System’s “Grand Juror’s Handbook.” Are jurors paid? The jury fee is $40 per day. If service extends beyond 30 days the court may authorize an additional $6 per day per juror. The fee is paid by the State or the employer depending on (1) the day of service and (2) the size of employer. Employers’ jury fee obligations are explained below.
