Service of an earnings withholding order creates a lien upon the earnings of the judgment debtor that are required to be withheld pursuant to the order and upon all property of the employer subject to the enforcement of a money judgment in the amount required to be withheld pursuant to such order. The lien continues for a period of one year from the date the earnings of the judgment debtor become payable unless the amount required to be withheld pursuant to the order is paid as required by law.
