I used to do expungements years ago for the county. People joining the police force have them done all the time. That's why I trip off the police, a lot of them have records they just went through the system. You have to be off of probation and if I remember correctly it has to be five years. When I used to prepare the paperwork for the judges they would deny them if it wasn't for employment. If a person wrote because I don't want a record on their application it was automatically denied. It takes away the conviction so an employer cannot hold that against you in "theory". DUI's get expunged all day if I remember correctly. Do not hire a lawyer to expunge it's a waste of money!
