In California, “expungement” usually refers to relief under Penal Code §1203.4 (and related sections). It allows a person who successfully completed probation to withdraw a previous plea of guilty or no contest and have the case dismissed.
It does not erase the arrest.
It does not seal the entire government file.
It does not eliminate the conviction for all purposes.
It does change how the case appears on most background checks and can materially improve employment prospects. It allows for a person to lawfully assert that they were not convicted of the case (in most circumstances)
