A person is eligible if in the five (5) years preceding the filing of the motion, if the conviction was for a misdemeanor, or in the ten (10) years preceding the filing of the motion if the conviction was for a felony, the petitioner has not been convicted nor arrested for any felony or misdemeanor, there are no criminal proceedings pending against the person, and he or she has exhibited good moral character.
The court must also find that petitioner's rehabilitation has been attained to the court's satisfaction and the expungement of the records of his or her conviction is consistent with the public interest. G.S. § 12-1.3-3.
