At Midland DWI arraignments, the judge tells the defendant to verify what they have been charged with and that their name on the file is correct. The judge then lets the defendant know what rights they have. It is a simple process, which is why if a person hires a lawyer right after their arrest. There may be no reason to have an actual arraignment.
However, some judges require that a person appears at the arraignment, even if they have obtained an attorney.
