If you have served time in a state prison for a felony offense, you will be unable to get your record expunged.  If you were convicted of a misdemeanor or a felony where you did not serve time in a state prison, you may be able to. If you were convicted of a felony but did not serve time in a state prison, you can petition to reduce your felony to a misdemeanor, complete court-ordered conditions such as probation, and file for expungement once all conditions are met. 

It is important to note that expungement does not erase your conviction, it just makes it so the public is unable to view it. You also cannot be facing active The process of getting your record expunged is as follows:

• Determine eligibility 
• Petition for reduction (if the felony needs to be reduced)
• File an expungement petition
• Attend a hearing: a judge will review your case and will make their decision based on certain factors; the severity of the crime, compliance with court orders, and evidence of rehabilitation. 
• Expungement decision: the judge will decide to grant or deny the request.
