S.C. Code Ann. § 62-5-428
(a) A conservator must pay from the estate all just claims against the estate and against the protected person arising before or after the conservatorship upon their presentation and allowance. A claim may be presented by either of the following methods:
(2) the claimant may file a written statement of the claim, in the form prescribed by rule, with the clerk of court and deliver or mail a copy of the statement to the conservator.
A claim is considered presented on the first to occur of receipt of the written statement of claim by the conservator or the filing of the claim with the court. Every claim which is disallowed in whole or part by the conservator is barred so far as not allowed unless the claimant files a petition for allowance in the court or commences a proceeding against the conservator not later than thirty days after the mailing of the notice of disallowance or partial disallowance if the notice warns the claimant of the impending bar. The presentation of a claim tolls any statute of limitation relating to the claim until thirty days after its disallowance.
