S.C. Code § 62-3-104
No claim may be filed against the estate of a decedent and no proceeding to enforce a claim against the estate of a decedent or his successors may be revived or commenced before the appointment of a personal representative, except as provided in Section 62-3-804(1)(b). After the appointment and until distribution, all proceedings and actions to enforce a claim against the estate are governed by the procedure prescribed by this article [Sections 62-3-101 et seq.]. After distribution, a creditor whose claim has not been barred may recover from the distributees as provided in Section 62-3-1004 or from a former personal representative individually liable as provided in Section 62-3-1005. This section has no application to a proceeding by a secured creditor of the decedent to enforce his right to his security except as to any deficiency judgment which might be sought therein.
