Under UIFSA, which state maintains continuing, exclusive jurisdiction for modification of child support orders?

The correct answer is the decree state, which is the state that issued the original child support order. Under the Uniform Interstate Family Support Act (UIFSA), the decree state holds continuing, exclusive jurisdiction to modify child support orders as long as one of the parties—typically the custodial parent or the non-custodial parent—remains a resident of that state.

This principle establishes stability and consistency in child support enforcement and modification, as it avoids conflicting orders from different states and allows for a clear jurisdictional authority. The decree state's continuing, exclusive jurisdiction helps to facilitate modifications that may be necessary due to changes in circumstances, ensuring that any alterations to support obligations occur within the legal framework originally established.

The other options do not maintain the same level of jurisdiction under UIFSA. While the custodial parent's current state or the state of the obligor may possess jurisdiction over some aspects of child support, they do not have the continuing authority to modify the support order unless they are the decree state. Thus, the decree state's role is central to upholding the integrity of child support modifications.
