S.C. Code § 34-28-610
Subject to Section 34-28-500, any association operating under this chapter and any federal savings and loan association authorized to conduct business in this State may accept a savings or other deposit account from any married person or minor as the sole and absolute owner of the account, receive payments thereon by or for the owner, pay withdrawals, accept pledges to the association, and act in any other matter with respect to the account of the married person or minor. Any payment or delivery of rights by an association to a married person or by a minor who holds a deposit account is a valid and sufficient release and discharge of the association for any payment so made or delivery of rights to the married person or minor. In the case of a minor, the receipt, acquittance, pledge, or other action required by the association to be taken by the minor is binding upon the minor with like effect as if he were of full age and legal capacity. The parent or guardian of the minor 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 the minor. However, in the event of the death of the minor, the receipt or acquittance of either parent or guardian of the minor is a valid and sufficient discharge of the association for any sum not exceeding, in the aggregate, two thousand five hundred dollars unless the minor shall have given written notice to the association to accept the signature of the parent or guardian for a larger sum.
