Article XVI--Additional Article

      That this Article shall provide additional remedies, and shall be binding only as among and between those party states which specifically execute the same.

      For the purposes of this Article, "child," as used herein, means any minor within the jurisdictional age limits of any court in the home state, and in this State means any person under eighteen years of age.

      When any child is brought before a court of a state of which such child is not a resident, and such state is willing to permit such child's return to the home state of such child, such home state, upon being so advised by the state in which such proceeding is pending, shall immediately institute proceedings to determine the residence and jurisdictional facts as to such child in such home state, and upon finding that such child is in fact a resident of said state and subject to the jurisdiction of the court thereof, shall within five days authorize the return of such child to the home state, and to the parents or custodial agency legally authorized to accept such custody in such home state, and at the expense of such home state, to be paid from such funds as such home state may procure, designate, or provide, prompt action being of the essence.
