South Carolina Additional Signature for Informal Administration is a process that allows a personal representative to act on behalf of an individual’s estate without obtaining formal Letters of Administration from the Probate Court. The Additional Signature process allows the personal representative to sign documents and perform certain duties related to the estate. In South Carolina, there are two types of Additional Signature for Informal Administration: the Small Estate Additional Signature and the Regular Estate Additional Signature. The Small Estate Additional Signature is available when the estate does not exceed $20,000, or when the estate is valued at less than $10,000 and the decedent’s only asset is a motor vehicle. The Small Estate Additional Signature requires the personal representative to sign an affidavit, which must be notarized and presented to the Clerk of Court. The affidavit must include a detailed description of the estate assets and liabilities, and must include the signatures of all heirs who are age 18 or over. The Regular Estate Additional Signature is available when the estate is valued greater than $20,000. This process requires the personal representative to complete and file an inventory and appraisal of the estate assets and liabilities. This must be signed and notarized by the personal representative, and must also include the signatures of all heirs who are age 18 or over. The Regular Estate Additional Signature must also be presented to the Clerk of Court.
