S.C. Code Ann. § 44-53-586
(b) The court may return any seized item to the owner if the owner demonstrates to the court by a preponderance of the evidence:
(2) in the case of a manager or an owner of a licensed rental agency, a common carrier, or a carrier of goods for hire, that any agent, servant, or employee of the rental agency or of the common carrier or carrier of goods for hire was not a party to, or privy to, or did not have knowledge of, the use of the property which made it subject to seizure and forfeiture.
If the licensed rental agency demonstrates to the court that it has rented the seized property in the ordinary course of its business and that the tenant or tenants were not related within the third degree of kinship to the manager or owner, or any agents, servants, or employees of the rental agency, then it is presumed that the licensed rental agency was not a party to, or privy to, or did not have knowledge of, the use of the property which made it subject to seizure and forfeiture.
