  • What to Expect: At the arraignment, the judge will formally advise you of the charges against you, your rights, and the potential penalties. You'll also be asked to enter a plea of guilty, not guilty, or no contest.
  • Entering a Plea: If you plead not guilty, the case will proceed to pre-trial hearings.
  • Getting a Court-Appointed Attorney: If you cannot afford an attorney, you can request a public defender at the arraignment.

2. Pre-Trial Hearings

3. Trial (If No Plea Deal)
