Iowa Code § 252D.23
An income withholding order entered by child support services pursuant to this chapter shall be filed with the clerk of the district court. In lieu of any signature on the order which may otherwise be required by law or rule, the order shall have affixed the name and address of child support services. For the purposes of demonstrating compliance by the payor of income, the copy of the withholding order or the notice of the order received, whether or not the copy of the order is file-stamped, shall have all the force, effect, and attributes of a docketed order of the district court including, but not limited to, availability of contempt of court proceedings against a payor of income for noncompliance. However, any information contained in the income withholding order or the notice of the order related to the amount of the accruing or accrued support obligation which does not reflect the correct amount of support due does not modify the underlying support judgment.
