S.C. Code Ann. § 15-19-320: Maximum undertaking in certain actions.

In actions when the purpose is to collect a debt for the purchase price of any property when such property, or any part thereof, is attached and in all actions when property is permitted to be attached to secure the payment of a debt claimed to be due, the undertaking required of the defendant shall in no case be in excess of double the amount of the debt claimed by the plaintiff to be due in the action. But if there is an appeal the court from which any appeal is taken may increase the bond.
