In any action in which support is ordered under a court child support order, the obligor or obligee under the order may file a motion with the court that issued the order requesting the issuance of one or more withholding or deduction notices under section 3121.03 of the Revised Code to pay the support due under the order. The motion may be filed at any time after the court child support order is issued. Upon the filing of a motion pursuant to this section, the child support enforcement agency shall immediately conduct, and shall complete within twenty days after the motion is filed, an investigation in accordance with section 3123.02 of the Revised Code. On the completion of the investigation, the court shall issue one or more appropriate orders described in section 3121.03 of the Revised Code.
