The 2001 addition of new Subsection (d) is to assure the tribunal is furnished with all the information needed to make a proper determination of the controlling order as well as the information needed to make a calculation of the consolidated arrears. The party or support enforcement agency requesting the determination of controlling order and determination of consolidated arrears is also required to notify all other parties and entities who may have an interest in either of those determinations. Those with such an interest most likely are support agencies and the obligee.

Relettered Subsection (e) provides that the determination of the controlling order under this section has the effect of establishing the tribunal with continuing, exclusive jurisdiction; only the order of that tribunal is entitled to prospective enforcement by a sister State.

Relettered Subsection (f) directs the forum tribunal to identify the details upon which it makes its determination of the controlling order. In addition, the tribunal is also directed to state specifically the amount of the prospective support, and to reconcile and consolidate the arrears and interest due on all of the multiple orders to the extent possible.

The party obtaining the determination is directed by relettered Subsection (g) to notify all interested tribunals of the decision after the fact. Although tribunals need not be given original notice of the proceeding, all tribunals that have contributed an order to the determination must be informed regarding which order was determined to be controlling, and should also be informed of the consolidated arrears and interest so that the extent of possible subsequent enforcement will be known with regard to each of the orders. The Act does not deal with the resolution of potential conflicting claims regarding arrears; this is left to case-by- case decisions or to federal regulation.

Section 207 presumes that the parties are accorded notice and opportunity to be heard by the tribunal. It also presumes that the tribunal will be fully informed about all existing orders when it is requested to determine which one of the existing multiple child support orders is to be accorded prospective enforcement. If this does not occur and one or more existing orders is not considered by the tribunal, the finality of its decision is likely to turn on principles of estoppel on a case-by-case basis. Finally, new Subsection (h), added in 2001, affirms the concept that when a fully informed tribunal makes a determination of the controlling order for prospective
