Serving on a jury is an important civic duty. Find out who is eligible for jury duty, how to respond to your summons, and what to expect when you serve. You'll also learn how to prove your jury service and what happens if you miss your date. To confirm if you'll be needed for jury duty, call the Juror Line listed on your Reminder Notice after 3 p.m. or log in to the Massachusetts Juror Service Website after 4 p.m. on the day before you're scheduled to serve.
