Iowa Code § 252H.10: Effective date of adjustment — modification.

1. Pursuant to section 598.21C, any administrative or court order resulting from an action initiated under this chapter may be made retroactive only from three months after the date that all parties were successfully served the notice required under section 252H.14A, 252H.15, or section 252H.19, as applicable.

2. The periodic due date established under a prior order for payment of child support shall not be changed in any order modified as a result of an action initiated under this chapter, unless child support services or the court determines that good cause exists to change the periodic due date. If child support services or the court determines that good cause exists, child support services or the court shall include the rationale for the change in the modified order and shall address the issue of reconciliation of any payments due or made under a prior order which would result in payment of the child support obligation under both the prior and the modified orders.
