If you're selected for jury service, you’ll be sent a 'jury summons'. This tells you the time and date you need to be at court. By law, you must do jury service when asked.
Once you receive a 'jury summons' you must complete and return it to the Jury Central Summoning Bureau within seven days from the day you get it. Once your jury service is confirmed, you must turn up on the agreed start date. If you don’t, you could be fined £1,000.
There are some situations when you can’t be on a jury. You cannot be selected for jury service if you are under eighteen years of age or if you’ve been in prison in the last 10 years.
