Really depends on what you're going to court for.
Nervous to go to court. What to expect?
The biggest thing I can tell you after years of being in and out of courts as a federal Officer is just be yourself and don't ever volunteer any more info than youre asked for as this is where so many hang their ownself and be polite with yes sir, and no sir.
Don't be afraid to ask whoever to explain if you don't understand something and expect any and everything in court so you won't be blind sided. Good luck
