South Carolina does allow the execution of judgments as follows:
"SECTION 15-39-10. Kinds of execution. [SC ST SEC 15-39-10]
There shall be three kinds of executions, (a) against the property of the judgment debtor, (b) against his person and (c) for the delivery of the possession of real or personal property or such delivery with damages for withholding the property. They shall be deemed the process of the court."
However, it appears that wages cannot be garnished in South Carolina.
You are correct, there is NO wage garnishment in South Carolina - wages are considered 100% exempt from garnishment.
I have found (I work as a judgment recovery specialist) that it is very difficult to get your money via a judgment in South Carolina - no wage garnishment, SC is not a community property state and many items are exempt from seizure. Still, we plod on and PRAY that they change some rules soon!
