S.C. Code Ann. § 38-43-440
[Until January 30, 2003, this section reads as follows:]
In the event that the insured or applicant for insurance fails to pay one or more installments within five days after the due date under any memorandum of the transaction delivered to him by the agent, agency, or producer, the agent, agency, or producer may call upon the insurer to cancel the policy and refund any unearned premiums on a pro rata basis to the agent, agency, or producer in discharge of the lien provided under Section 38-43-410. The insurer, upon paying any refund of unearned premiums accompanied by a statement detailing the computation, a copy of which is mailed to the insured at the address shown in the policy, has no further liability to the insured with respect to the return of unearned premiums.
In the event of any other refund of unearned premium resulting from termination of the policy, reduction in the premium, or otherwise, the refund of premium must be made to the agent, agency, or producer in recognition of his, or its, lien, and payment of the refund to the agent, agency, or producer by the insurer accompanied by a statement detailing the computation, a copy of which is mailed by the insurer to the insured at the address shown in the policy, except as to errors in the computation, discharges the insurer's obligation to the insured with respect to the refund.
Failure of an agent, agency, or producer to declare a default or move to perfect his or its lien because of the insured's failure to pay when due one or more installments of his obligation for premium advanced does not constitute a waiver on the part of the agent, agency, producer, or insurer nor is the agent, agency, or producer estopped or precluded from asserting and perfecting the lien with respect to any subsequent default nor is the insurer estopped or precluded from recognizing and discharging the lien with respect to the subsequent default.
[From and after January 31, 2003, this section reads as follows:]
