S.C. Code § 15-19-530
The sheriff or constable to whom such warrant is directed and delivered shall immediately attach the real estate or personal property of the defendant which is described in the warrant and hold it until further order of the court. When real estate is attached a true and attested copy of such warrant shall be, by the officer serving it, delivered to the defendant or left at his last or usual place of residence, and the officer making such service shall also leave a true and attested copy of such warrant of attachment in the office in which, by law, a deed of such estate is required to be recorded. If the party whose estate is attached does not reside in this State then such copy shall be delivered to his tenant, agent or attorney, if any be known, and if no such agent, tenant or attorney be known then a copy of such warrant of attachment, with the officer's return thereon, lodged in the office in which, by law, a deed of such real estate ought to be recorded, shall be deemed sufficient service. The clerk or register of the office wherein the warrant of attachment is required to be lodged shall receive such warrant and enter in a book kept for that purpose the names of the parties, the date of the warrant of attachment, the sum demanded and the officer's return thereon.
