A garnishee order is an order issued by the Court requiring the party to whom the order is addressed to make payments in satisfaction of a judgment debt to the judgment creditor. (Some courts now refer to garnishees as money redirection orders).

The third party to whom the order is addressed is the “garnishee”. Under a garnish order the garnishee is directed to pay money that would ordinarily be payable to the judgment debtor directly to the judgment creditor or into Court.
