This section is affected by 2009 Wis. Act 321 effective the date stated in the notice published in the Wisconsin Administrative Register under s. 769.904 to read:

769.207 Determination of controlling child support order. (1c) If a proceeding is brought under this chapter and only one tribunal has issued a child support order, the child support order of that tribunal is controlling and must be recognized.

(1m) If a proceeding is brought under this chapter, and 2 or more child support orders have been issued by tribunals of this state, another state, or a foreign country with regard to the same obligor and child, a tribunal of this state having personal jurisdiction over both the obligor and individual obligee shall apply the following rules and by order shall determine which child support order controls and must be recognized:

(a) If only one of the tribunals would have continuing, exclusive jurisdiction under this chapter, the child support order of that tribunal controls.

(b) If more than one of the tribunals would have continuing, exclusive jurisdiction under this chapter, a child support order issued by a tribunal in the current home state of the child controls, or, if a child support order has not been issued in the current home state of the child, the child support order most recently issued controls.

(c) If none of the tribunals would have continuing, exclusive jurisdiction under this chapter, the tribunal of this state shall issue a child support order, which controls.

(1r) If 2 or more child support orders have been issued for the same obligor and same child, upon the request of a party who is an individual or that is a support enforcement agency, a tribunal of this state having personal jurisdiction over both the obligor and the obligee who is an individual shall determine which child support order controls under sub. (1m). The request may be filed with a registration for enforcement or registration for modification under subch. VI, or may be filed as a separate proceeding.

(1t) A request to determine which is the controlling child support order must be accompanied by a copy of every child support order issued for the obligor and child that is in effect and the applicable record of payments. The requesting party shall give each party whose rights may be affected by a determination of which child support order controls notice of the request for that determination.

(2) The tribunal that issued the order that is controlling under sub. (1c), (1m), or (1r) has continuing jurisdiction to the extent provided in s. 769.205 or 769.206.

(3) A tribunal of this state that determines by order which child support order is controlling under sub. (1m) (a) or (b) or (1r), or that issues a new child support order that is controlling under sub. (1m) (c), shall state in that order all of the following:

(a) The basis upon which the tribunal made its determination.

(b) The amount of prospective support, if any.

(c) The total amount of consolidated arrears and accrued interest, if any, under all of the orders after all payments made are credited as provided by s. 769.209.

(4) Within 30 days after the issuance of an order determining which child support order is controlling, the party that obtained the order shall file a certified copy of the order with each tribunal that had issued or registered an earlier child support order. Failure of the party obtaining the order to file a certified copy of the order as required by this subsection subjects the party to appropriate sanctions by a tribunal in which the issue of failure to file arises, but that failure has no effect on the validity or enforceability of the controlling child support order.

(5) An order that has been determined to be the controlling child support order, or a judgment for consolidated arrears of support and interest, if any, made under this section, must be recognized in proceedings under this chapter.
