Requesting Disclosure

How do I request disclosure of evidence for a trial? I've read that I submit a request to court and I've also read I contact the officer in charge. I'm not sure which one is accurate or if I do both.

When I get the disclosure, what should I look for to help my case (driving without license - license was expired and I wasn't aware.

Thanks.

You put forth your request to the court, the address is on the back of the ticket..... There are also plenty of topics about this here.
