S.C. Code Ann. § 37-2-709

(1) With respect to a consumer rental-purchase agreement, an assignee of the rights of the lessor is subject to all claims and defenses of the consumer against the lessor arising from the lease of property or services, notwithstanding that the assignee is the holder in due course of a negotiable instrument issued in violation of the provisions prohibiting certain negotiable instruments (Section 37-2-708). (2) A claim or defense of a consumer specified in subsection (1) may be asserted against the assignee under this section only if the consumer has made a good faith attempt to obtain satisfaction from the lessor with respect to the claim or defense and then only to the extent of the amount owing the assignee with respect to the sale or lease of the property or services as to which the claim or defense arose at the time the assignee has written notice of the claim or defense. Written notice of the claim or defense may be given before the attempt specified in this subsection. For the purposes of this section, written notice is any written notification other than notice on a coupon, billing statement, or other payment medium or materials supplied by the assignee. (3) An agreement may not limit or waive the claims or defenses of a lessee under this section.
