S.C. Code § 15-19-290
If the person in whose possession property shall be attached shall appear at the return of the writ and file his answer thereto and deny the possession or control of any property belonging to the defendant or claim the money, lands, goods and chattels, debts and books of account as creditor in possession, or in his own right or in the right of some third person, or if any of the property be claimed by any other person than such defendant, then, if the plaintiff be satisfied therewith, the party in possession shall be dismissed and the plaintiff may pay the cost of his action. But if the plaintiff shall contest the return or the claim of such third person an issue shall be made up under the direction of the judge to try the question, and the party that shall prevail in the issue shall recover the cost of such proceeding of the opposite party, and judgment shall be given accordingly. If the party in possession or the third person claiming the property, as the case may be, resides in a different county from that in which the action is brought and an issue be made up between him and the plaintiff the action shall be tried in the county in which the party in possession resides. In case the property is claimed by a third person the plaintiff shall execute to such person the same undertaking that he is now required to give under Section 15-19-80. Such undertaking shall be executed within ten days after notice of such claim.
