S.C. Code Ann. § 38-71-50: Alteration of application.

No alteration of any written application for insurance by erasure, insertion, or otherwise may be made by any person other than the applicant without his written consent, and the making of any such alteration without the consent of the applicant is a misdemeanor. However, insertions may be made by the insurer, for administrative purposes only, in a manner that clearly indicates that the insertions are not to be ascribed to the applicant.
