(A) A party contesting the validity or enforcement of a registered order bears the burden of proving one or more of the following defenses:
(1) the issuing tribunal lacked personal jurisdiction over the contesting party;
(2) the order was obtained by fraud;
(3) the order has been vacated, suspended, or modified by a later order;
(4) the issuing tribunal has stayed the order pending appeal;
(5) there is a defense under the law of this State to the enforcement remedy sought;
(6) full or partial payment has been made; or
(7) the statute of limitations under Section 20-7-1138 precludes enforcement of any arrearage.

Any uncontested portion of the registered order may be enforced by all remedies available under the law of this State.
(C) If the contesting party does not establish a defense under subsection (A) to the registration of the order, the registering tribunal shall issue an order confirming the order.
