Miss. Code Ann. § 81-14-375

The owner of a deposit account may transfer his rights therein absolutely or conditionally to any other person eligible to hold such rights, but such transfer may be made on the books of the savings bank and accompanied by the proper application for transfer by the transferor and transferee. Such transferor and transferee shall accept such account subject to the terms and conditions of the account contract, the bylaws of the savings bank, the provisions of its certificate of incorporation, and all rules and regulations of the commissioner. Notwithstanding the effectiveness of such a transfer between the parties thereto, the savings bank may treat the holder of record of a deposit account as the owner thereof for all purposes, including payment and voting, until such transfer and assignment has been recorded by the savings bank.
