A garnishment merely freezes the debtor's property in the hands of the garnishee, but an execution requires the person holding the debtor's property to release it to the creditor.
The Writ of Execution authorizes the Constable or Sheriff to seize non-exempt property from the Judgment- Debtor and sell it to satisfy the judgment against him/her.
What Is a Writ of Execution? A writ of execution is a court order that puts in force a judgment of possession and directs law enforcement personnel to begin the transfer of property as the result of a legal judgment.
The writ of garnishment is a court order requiring the garnishee to withhold a certain amount from your earnings and to continue to withhold a portion of your earnings until the judgment is satisfied or the writ is quashed by the court or released by the judgment creditor.
