When you arrive to the San Marcos Justice courtroom, go through the door, sit down and stay quiet. If there is a clipboard, you should sign in. The cases will be called by the order of the list. You do not want to wait hours to then realize that you needed to sign in. If you have hired a private attorney, wait for them in the courtroom or as instructed. If you have not hired an attorney, then wait for the Judge, Clerk or Prosecutor to call your name.
