My question involves expungements or pardons for the state of: NC

11 years ago, i was charged with "uttering" a forged instrument. my neighbor gave me a piece of mail to give to her girl friend when she came home from work ( myneighbor was gone to work already). when her GF got home i stopped her inthe driveway and gave her the mail (unopened) to her. a few weeks later detectives came to my house and said that i was being charged with "uttering" a forged instrument. because the mail that i gave to the GF was a stolen check that both the GF and my neighbor had stolen and cashed. my only part in the whole thing was the fact that i gave the mail to the GF. i was arrested and released a few hours later. and given probation and community services. but this is a felony on my record, how can i get this expunged?
