Can these two misdeameanors on his record from six years ago removed from his record?

The waiting period for a Class B misdemeanor is 4 years, a Class A is five years. Those dates start from the time probation ended. Assuming he is not disqualified on other grounds (for example, too many other convictions), it is possible that he is eligible now for expungement. It is a lengthy process, so you should see an attorney as soon as possible to get started.

Only certain types of misdemeanors or felonies can be expunged, and only after 10 years (for misdemeanors) or 20 years (for felonies) have passed since the conviction without being arrested on any other misdemeanor or felony.
