Under the Revised Uniform Reciprocal Enforcement of Support Act (RURESA), once a child support order is issued, it becomes enforceable by family courts in all states. This means a parent cannot "escape" a child support order simply by moving to another state. In essence, the order "follows" him/her.
Under RURESA, the allocated parent can collect support in two ways:
Register the order in the county where the supporting parent has moved to.
Have the family court in his/her home state commence an action to enforce the support.
