S.C. Code Ann. § 62-3-1005
Unless previously barred by adjudication and except as provided in the accounting, the rights of successors and of creditors whose claims have not otherwise been barred against the personal representative for breach of fiduciary duty are barred unless a proceeding to assert the same is commenced within six months after the filing of the account, proposal for distribution of the estate, petition for settlement of the estate, and proofs required by Section 62-3-1001. The rights thus barred do not include rights to recover from a personal representative for fraud, misrepresentation, or inadequate disclosure related to the settlement of the decedent's estate.
