S.C. Code Ann. § 34-30-1630
(A)
(D) When a deposit account is held in a state savings bank by a person residing in another state or country, the account with its additions and earnings, or any part of it, is exempt from taxation otherwise imposed by this State and may be paid to the administrator or executor appointed in the state or country where the account holder resided at the time of death; provided, the administrator or executor has furnished the state savings bank with:
(3) that there are no creditors of the estate in this State.
Upon payment or delivery to the representatives after receipt of the affidavit and authenticated copies, the state savings bank is released and discharged to the same extent as if the payment or delivery had been made to a legally qualified resident, executor, or administrator, and is not required to see to the application or disposition of the property. An action at law or in equity may not be maintained against the state savings bank for payment made in accordance with this section.
