§ 580-612 Recognition of order modified in another state

If a New York court issued a child support order, and another state later changes that order under the proper legal process, New York courts still have a role to play. But that role becomes limited once the modification happens.

New York can still enforce its original order, but only for payments and interest that built up before the other state changed it. If someone violated the New York order before the change took effect, New York courts can still take action on that violation. However, New York courts cannot enforce the original terms going forward once another state has properly modified them.

Once the other state's new order is registered in New York, New York courts must recognize and enforce that updated order. This means the most recent, properly issued order from the other state becomes the one that counts going forward. This system prevents confusion and stops two states from enforcing conflicting support orders at the same time.
