S.C. Code Ann. § 63-17-1550: Payor's wilful failure to withhold.

If a payor wilfully fails to withhold or pay over income pursuant to a notice to withhold, the court upon notice and hearing may enter judgment and direct the issuance of an execution against the payor for the total amount that the payor wilfully failed to withhold. A payor who wilfully refuses to hire or who discharges or otherwise penalizes an obligor as prohibited by Section 63-17-1460(I) or who fails to notify the clerk of the availability of health insurance is subject to a civil fine not to exceed five hundred dollars which may be imposed by the court in its discretion.
