S.C. Code Ann. § 18-9-130
A notice of appeal from a judgment directing the payment of money shall not stay the execution of the judgment unless the presiding judge before whom the judgment was obtained shall grant a stay of execution; but after notice of appeal has been given the plaintiff shall not enforce a sale of property without giving an undertaking or bond to the defendant, with two good sureties, in double the appraised value of the property or double the amount of the judgment, conditioned to pay all damages which the defendant may sustain by reason of such sale in case the judgment is reversed. Nor shall the plaintiff in such case be allowed to proceed with a sale of defendant's property if the defendant do enter into an undertaking, with good sureties, in double the appraised value of the property or the amount of the judgment, to pay the judgment with legal interest and all costs and damages which the plaintiff may sustain by reason of the appeal or to produce the property levied on and submit to the sale in case the judgment be confirmed.
