N.C. Gen. Stat. § 54B-135
The owner of a withdrawable account may transfer his rights therein absolutely or conditionally to any other person eligible to hold the same but such transfer may be made on the books of the association only upon presentation of evidence of transfer satisfactory to the association, and accompanied by the proper application for transfer by the transferor and transferee, who shall accept such account subject to the terms and conditions of the savings contract, the bylaws of the association, the provisions of its certificate of incorporation, and all rules and regulations of the Commissioner of Banks. Notwithstanding the effectiveness of such a transfer between the parties thereto, the association may treat the holder of record of a withdrawable account as the owner thereof for all purposes, including payment and voting (in the case of a mutual association) until such transfer and assignment has been recorded by the association.
