You can bring a book or magazine to court with you to help pass the time. You should not bring a newspaper.
What Should I Do when I Get to Court?
Come inside and sit down on one of the benches. You'll have to pass through a metal detector so make sure that you're ready for that. If you're wearing a hat, you'll have to take it off in the courtroom and the should not chew gum in the courtroom.
Do I Need to Check in With Anyone when I Get to Court?
No. The judge will just call out your name when he's ready to hear your case. You don't need to inform anyone that you've arrived.
