S.C. Code § 63-17-1600
When a delinquency occurs as defined in Section 63-17-1410, the obligor must be given notice pursuant to Section 63-17-1440 of the proposed lien. Where no petition to stay service is timely filed or where no relief is granted to the obligor pursuant to Section 63-17-1450, the arrearage may be recorded or provided for in Section 63-17-1460 in the appropriate index in the office of the Clerk of Court or Register of Deeds. Upon recordation the arrearage has the same force and effect as a judgment and it is cumulative to the extent of any and all past due support, until the arrearage is paid in full. The judgment may be recorded in any county in which the obligor resides or in which he owns real property by the filing of a transcript of judgment in that county. A lien imposed pursuant to this section is not dischargeable in bankruptcy.
