S.C. Code § 56-19-1020
When a person who is not a licensed ATV dealer receives by purchase, gift, trade, or by another means a vehicle that was titled in this State, the person who receives the vehicle may make application to the department for a title. The application must be accompanied by the required documents and fee for title. The department shall issue a certificate of title once it has received a properly completed application. An owner of an ATV, before the effective date of this article, who cannot provide proof of ownership, may request an affidavit from the sheriff in the county in which he resides. The affidavit shall state that the sheriff finds the person making application for the title is the legal owner of the ATV. Before issuing the affidavit, the sheriff must verify through the National Crime Information Center that the ATV is not stolen. The department shall issue a title application to the owner upon presentation of the affidavit, application, and fee.
