Mississippi Code Title 81. Banks and Financial Institutions § 81-12-135

An association and any federal association may issue savings accounts to any minor or other person under disability as the sole and absolute owner of such savings account, and receive payments thereon by or for such owner, and pay withdrawals, accept pledges to the association, and act in any other manner with respect to such accounts on the written instruction of such savings account holder in accord with this chapter. Any payment or delivery of rights to any minor or other person under a disability, or a receipt or acquittance signed by a minor or other person under a disability, who holds a savings account, shall be a valid and sufficient release of such association for any payment so made or delivery of rights to such minor or person. The receipt, acquittance, pledge or other action required by the association to be taken by such minor or person shall be binding upon such minor or person with like effect as if he were of full age and legal capacity. The parent or guardian of such minor or person shall not in his capacity as parent or guardian have the power to attach or in any manner to transfer any savings account issued to or in the name of such minor or person; provided, however, that in the event of the death of such minor or person the receipt or acquittance of either parent, a person standing in loco parentis, guardian or conservator of such minor or person shall be a valid and sufficient discharge of such association for any sum or sums not exceeding in the aggregate One Thousand Dollars ($1,000.00) unless the minor or person shall have given written notice to the association not to accept the signature of such person.
