Good question. If you are presently on probation and you and your probation officer have differences, it does not help either one of you to continue on with the situation. The bets way for you to possibly get a different assigned probation officer is to have a criminal defense attorney write the probation department stating in a detailed letter the problems you are having with the assigned officer and request a new assigned probation officer to your case.If that request is not granted, the recourse is for the criminal defense attorney to file a petition in the county and state where you had your criminal matter seeking a new probation officer. The court will hear the motion and make a decision on the request.
