N.C. Gen. Stat. § 116B-58
A record of the issuance of a check, draft, or similar instrument is prima facie evidence of an obligation. In claiming property from a holder who is also the issuer, the Treasurer's burden of proof as to the existence and amount of the property and its abandonment is satisfied by showing issuance of the instrument and passage of the requisite period of abandonment. Defenses of payment, satisfaction, discharge, and want of consideration are affirmative defenses that must be established by the holder. In asserting these affirmative defenses, a holder who is also the issuer may satisfy the holder's burden of proof by showing a written acknowledgement by the payee of a check, draft, or similar instrument that no obligation is owed the payee.
