S.C. Code Ann. § 30-5-16

On the effective date of SECTIONS 30-5-15 and 30-5-16, in those counties which have a register of deeds, all current records pertaining to state tax liens shall be maintained in the office of the register of deeds unless otherwise directed by the governing body of the county concerned. The register of deeds may begin a new record book of state tax liens beginning with liens filed after August 1, 1978, but such book shall note on the cover that the records of the clerk of court relating to state tax liens are on file in the office of the clerk of court and contain a record of state tax liens which are still effective.
