Without knowing more about your situation, all I can say is that it depends. I think you need to get an attorney before your court date. Find someone local who knows the judges and prosecutors at the courthouse where your case being heard. Also, make sure your attorney has the right experience to represent you -- someone who focuses their practice on criminal defense and who has had success in the past defending clients in similar situations.
