[1] We first decide whether the Attorney General of North Carolina had standing to file a brief on behalf of the plaintiff-appellant mother. The father argues that this case is a “private matter” of conversion of property by the mother, and therefore was not within the statutory authority allowing the Attorney General to represent the mother. We disagree. The issue here is enforcement of orders rendered in an action to register a foreign child support order. There is ample statutory authority obligating the Attorney General to represent the child support obligees on appeal. See N.C. Gen. Stat. §§ 52A-10.1 (URESA), 52C-3-308 (UIFSA) and 114-2. Accordingly, we hold that representation of the mother by the Attorney General is proper.
[2] The central issue here is whether the district court had jurisdiction to order the mother to cease and desist from support collections on 16 December 1988 and then to hold the mother in contempt of the cease and desist order on 29 July 1998. After careful consideration of the briefs and record, we hold that upon dismissal of the URESA action in 1988, the subsequent orders were void for lack of subject matter jurisdiction.
The father, Defendant Paugh, argues that jurisdiction is proper because (1) by filing the URESA petition, the mother submitted the entire issue of child support, including paternity, to the court, (2) the mother refused to submit to court-ordered paternity testing, and then [3] the mother continued collection efforts (termed “conversion” by the father) in New York despite a North Carolina cease and desist order. The father argues that “[i]t would not be good policy for this state, in the name of ‘full faith and credit,’ to allow and encourage another person or state to flaunt [sic] the laws of this state under the guise of uniformity” by asserting lack of jurisdiction as a defense.
Moreover, the father contends that “there is no presumption . . . that the [New York] child support order ... is valid and enforceable without further inquiry under the law of the responding state.” He maintains that the 1988 cease and desist order is a valid basis for *438“other relief’ granted by the court, exercising expansive “jurisdiction over all aspects of the . . . child support case,” including recovery of “converted” funds under the 1998 contempt citation. Pinner v. Pinner, 33 N.C. App. 204, 206 S.E.2d 633, 635 (1977) (URESA initially provides for “registration, and if required, a hearing on whether to vacate the registration or grant the ‘obligor’ other relief”).
We disagree.
A support obligee may register a foreign support order pursuant to URESA “if the duty of support is based on a foreign support order.” N.C. Gen. Stat. § 52A-25; see Williams v. Williams, 97 N.C. App. 118, 121-22, 387 S.E.2d 217, 219 (1990). A North Carolina court hearing an obligee’s challenge to confirmation of a foreign support order under N.C. Gen. Stat. § 52A-30 may dismiss the obligee’s action to register the order (or refuse to confirm the registration) for lack of jurisdiction where it finds the obligor owes no duty of support to the obligee. N.C. Gen. Stat. §§ 52A-12-14. See Pifer v. Pifer, 31 N.C. App. 486, 489, 229 S.E.2d 700, 702-03 (1976) (“if the court of the responding state finds a duty of support, it may order the defendant to furnish support”); 2 Lee, North Carolina Family Law, § 169 at 342, 343. Pursuant to N.C. Gen. Stat. § 52A-8, our courts have held that the duty of support question is to be resolved under the “law of the state where the obligor was present during the legally material times provided for in the statute.” Williams at 122, 387 S.E.2d at 219 (citing Pieper v. Pieper, 323 N.C. 617, 374 S.E.2d 275 (1988)). Accord Reynolds v. Motley, 96 N.C. App 299, 385 S.E.2d 548 (1989). North Carolina law applies here, since plaintiff-appellant does not present evidence to rebut the statutory presumption that the obligor was present in North Carolina during “the period or any part of the period for which support is sought.” N.C. Gen. Stat. § 52A-8; Williams at 121, 387 S.E.2d at 219.
The North Carolina version of URESA grants obligor fathers the right to a determination of paternity, a condition precedent to a duty of support. N.C. Gen. Stat. § 52A-8.2; Reynolds at 304-05, 385 S.E.2d at 551. A prior adjudication of paternity by a foreign court of competent jurisdiction must be accorded full faith and credit in North Carolina. See N.C. Gen. Stat. § 110-132.1. Thus, once a foreign court of competent jurisdiction issues an order of support adjudicating the issue of paternity, principles of full faith and credit mandate that the issue not be relitigated under URESA in North Carolina. Brondum v. Cox, 292 N.C. 192, 199, 232 S.E.2d 687, 691 (1977). The father here *439does not allege that the New York court’s adjudication of paternity was error, nor did the father timely challenge or appeal the New York support orders in 1978 or 1984. Thus, the Union County District Court failed to accord full faith and credit to the valid New York determination of paternity and had no authority to invite relitigation of the paternity issue by ordering blood testing. The district court erroneously dismissed the mother’s case in 1988 on the basis of her refusal to obey the invalid order to undergo testing. But because the mother failed to timely appeal the dismissal of her URESA action, we do not base our decision on that portion of the district court’s ruling.
[3] The dispositive issue is whether the district court had jurisdiction to issue the 1998 contempt order based on the mother’s disobedience of the cease and desist portion of the 1988 order. With very few exceptions, URESA does not confer jurisdiction on North Carolina courts to prevent a mother, a New York resident, from asserting her right to collect child support under a valid, unappealed-from New York court order for child support. This Court held in Fleming v. Fleming, 49 N.C. App. 345, 349-50, 271 S.E.2d 584, 587 (1980) that:
The full faith and credit clause . . . requires that the judgment of the court of one state must be given the same effect in a sister state that it has in the state where it was rendered. A decree for the future payment of alimony or child support is, as to installments past due and unpaid, within the protection of . . . the Constitution. [Citations omitted.]
Here, the mother seeks to register a New York court order for child support to collect back child support owed on the New York court order from a North Carolina resident. Despite an unappealed-from prior adjudication of paternity in New York, the putative father seeks to avoid his parental duty of support by asserting in North Carolina that the children are not his offspring.
Under Fleming, we must accord full faith and credit to the New York order “unless by the law of the state in which the decree was rendered[,] its enforcement is so completely within the discretion of the courts in that state that they may annul or modify the decree as to overdue and unsatisfied installments.” Id. (emphasis added). Thus, we first examine the discretion accorded to New York courts issuing orders for child support under New York law. We find that while New York courts may modify or cancel child support arrearages, New York *440Domestic Relations Law § 244 (McKinney 1999), they may not allow a father to collaterally attack support orders on the issue of paternity where paternity was judicially determined as part of prior divorce and support proceedings. Jeanne M. v. Richard G. 465 N.Y.S.2d 60 (1983), Matter of Montelone v. Antia, 400 N.Y.S.2d 129 (1977), Matter of Sandra I. v. Harold I., 388 N.Y.S.2d 376 (1976). Because New York courts have no apparent discretion to annul or modify the prior New York paternity orders, the child support order here is fully protected by the full faith and credit clause pursuant to Fleming.
In addition, this Court has held that valid foreign support decrees are immune to collateral attack in North Carolina unless (1) the foreign court lacked jurisdiction over the obligor at the relevant time, (2) there was fraud in the procurement of the decree in the foreign court, or (3) the foreign decree is against the public policy of North Carolina. Pieper v. Pieper, 108 N.C. App. 722, 725, 425 S.E.2d 435, 436 (1993) (citing McGinnis v. McGinnis, 44 N.C. App. 381, 388, 261 S.E.2d 491, 496 (1980)). Since the father here argues none of these exceptions, we conclude that constitutional considerations make it “improper to permit an alteration or re-examination of the judgment, or of the grounds on which it is based.” Fleming at 345, 271 S.E.2d at 587 (citing Sears v. Sears, 253 N.C. 415, 417, 117 S.E.2d 7, 9 (I960)). The full faith and credit clause therefore limits the scope of the district court’s jurisdiction to approving or dismissing the registration action in light of relevant North Carolina law. We hold that the district court had no jurisdiction to prevent a nonresident support obligee (the mother) from asserting her rights under a valid foreign court order.
Absent the expansive jurisdiction argued by defendant-appellee father, once the district court dismissed the URESA action with prejudice in 1988, the case ended and jurisdiction terminated. N.C. R. Civ. P. 41(b); Barnes v. McGee, 21 N.C. App. 287, 204 S.E.2d 203 (1974). Therefore, the subsequent cease and desist portion of the 1988 order and 1998 contempt order were void for lack of subject matter jurisdiction. Harding v. Harding, 46 N.C. App. 62, 64, 264 S.E.2d 131, 132 (1980) (“defendant cannot be held in contempt for his failure to comply with void portions” of an order).
We hold that the defendant-appellee father may not avoid his support obligations in New York by pleading a paternity defense to confirmation of the mother’s URESA filing in North Carolina. Because we hold that the 1988 and 1998 orders are void for lack of subject matter jurisdiction due to constitutional and procedural limitations *441on the district court which issued them, we need not discuss defendant-appellee father’s remaining arguments as to the validity of the orders.
