S.C. Code § 34-30-1620
A state savings bank operating under this chapter and a federal savings institution conducting business in this State may accept a savings or other deposit account from a married person or minor as the sole and absolute owner of the account, receive payments by or for the owner, pay withdrawals, accept pledges to the state savings bank, and act in other matters with respect to the account of the married person or minor. A payment or delivery of rights by a state savings bank to a married person or by a minor who holds a deposit account is a valid and sufficient release and discharge of the state savings bank for payment so made or delivery of rights to the married person or minor. In the case of the minor, the receipt, acquittance, pledge, or other action required by the state savings bank 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 otherwise transfer a savings account issued to or in the name of the minor. However, if the minor dies, the receipt or acquittance of either parent or guardian of the minor is a valid and sufficient discharge of the state savings bank for a sum not exceeding, in the aggregate, two thousand five hundred dollars unless the minor had given written notice to the state savings bank to accept the signature of the parent or guardian for a larger sum.
