S.C. Code Ann. § 34-15-40

In all proceedings in the probate court or elsewhere connected with any authority exercised under the provisions of Section 34-15-10 or under any similar provisions of law all accounts, returns and other papers may be signed and sworn to in behalf of the corporation by any officer thereof duly authorized by it. The answer and examination under oath of such officer shall be received as the answer and examination of the corporation. The court may order and compel an officer of such corporation to answer and attend the examination in the same manner as if he, instead of the corporation, were a party to the proceeding.
