N.C. Gen. Stat. § 42-55
If the landlord or the landlord's successor in interest fails to account for and refund the balance of the tenant's security deposit as required by this Article, the tenant may institute a civil action to require the accounting of and the recovery of the balance of the deposit. The willful failure of a landlord to comply with the deposit, bond, or notice requirements of this Article shall void the landlord's right to retain any portion of the tenant's security deposit as otherwise permitted under G.S. 42-51. In addition to other remedies at law and equity, the tenant may recover damages resulting from noncompliance by the landlord; and upon a finding by the court that the party against whom judgment is rendered was in willful noncompliance with this Article, such willful noncompliance is against the public policy of this State and the court may award attorney's fees to be taxed as part of the costs of court.
