How Long do Felony or Misdemeanor Charges Last?
Felony crimes will stay on your record for life. Montana does allow, however, some misdemeanors to be expunged from your record following a five-year waiting period. You must also comply with a list of requirements, and you must be free of any further convictions. If you qualify, you can petition the court for expungement. You will have to wait about 30 days for the results. All other crimes will remain on your criminal record forever.
