COMMENT
Subsection (a) requires the registering tribunal to provide notice to the nonregistering party of the effect of registration. After such notice is given, absent a successful contest by the nonregistering party, the order will be confirmed and future contest will be precluded. The notice contemplates far more than merely announcing an intent to initiate enforcement of an existing support order. The registered order or orders and other relevant documents and information must accompany the notice, including details about the alleged arrears.
Subsection (b) provides the nonregistering party with a wealth of information about the proceeding, including that: (1) the order is immediately enforceable; (2) a hearing must be requested within a relatively short time; (3) failure to contest "will result" in a confirmation of the order (roughly the equivalent of a default judgment); and (4) the amount of arrears, if any. Initially subsection (b) made the suggestion, via brackets, that [20] days be the time within which a request for a hearing to contest the support order be made. The rationale for this relatively short period was that the matter had already been litigated, and the obligor had already had the requisite "day in court," and was allegedly in default of a known order. Moreover, advocates of child-support enforcement stressed the necessity of quick resolution of an instance of nonsupport.
On the other hand, the Convention requires notice of hearing to be within a fixed time of 30 days, and further a fixed time of 60 days if the respondent resides in a foreign country. See Convention art. 23(6). This difference between UIFSA and the Convention is accommodated in Section 707. The time frame for notice of registration for an interstate support order and a foreign support order not subject to the Convention will be established by local law.
Subsection (c) is the correlative to Section 602 regarding the notice to be given to the nonregistering party if determination of a controlling order must be made because of the existence of two or more child-support orders. The petitioner requesting this affirmative relief is directed to identify the order alleged to be controlling under Section 207.
Subsection (d) states the obvious; i.e., the obligor's employer also must be notified if income is to be withheld. Often this will not be necessary if the employer has already been notified by the responding state's enforcement agency via the administrative process established in Section 507.
