If a party ordered to pay child support and all statutory fees and costs related to expenses incurred on behalf of the child, or any portion of them, pursuant to § 26-7A-98 or pursuant to a court order under any other applicable statute, is employed for wages, salary, or commission, the court may order that the amount of child support, fees, and costs to be paid by the party shall be paid to the guardian or institution out of the party's wages, salary, or commission, and the party shall accordingly execute an assignment. The court may also order the party obligated to pay child support, fees, and costs, or any portion of them, to periodically make complete disclosure to the court of the party's place or places of employment and the amount and nature of earnings. If the party fails to obey the order of the court, the party may be punished as for civil contempt.
