UIFSA Long-Arm Proceedings Are “One-State” Cases: RSA 546-B:31 Does Not Bar New Hampshire Support Orders When Personal Jurisdiction Exists

Case: In the Matter of Stansfield & Patti, 2026 N.H. 17 (N.H. Apr. 23, 2026)
Court: Supreme Court of New Hampshire

1. Introduction

This appeal arose from a New Hampshire parenting petition filed by Jill Stansfield (mother) against Todd Patti (father), the unmarried parents of two children. After the parties separated and the father stopped contributing financially, the mother sought final parenting orders including child support. The father did not appear, and the Circuit Court approved a parenting plan after a default hearing but declined to issue child support and related support orders.

The central issue was jurisdictional: although the trial court concluded it had personal jurisdiction over the father, it ruled it lacked subject matter jurisdiction to establish support because it read RSA 546-B:31 (UIFSA, Article 4) to permit a “responding tribunal” to issue an initial support order only when the person seeking support resides outside New Hampshire. The Supreme Court reversed, holding that the trial court misapplied UIFSA and that Article 4’s “responding tribunal” limitation did not govern this case.

2. Summary of the Opinion

The Supreme Court of New Hampshire held that the circuit court had subject matter jurisdiction to award child support and issue related support orders. It concluded that RSA 546-B:31 did not apply because the mother proceeded under UIFSA’s long-arm personal jurisdiction provisions, making the case a “one-state proceeding.” In that posture, RSA 546-B:11-a directs that Articles 3 through 6 (including Article 4’s RSA 546-B:31) do not apply except as specified, and the tribunal must apply New Hampshire procedural and substantive law.

The Court therefore reversed the denial of support orders and remanded for further proceedings.

3. Analysis

3.1 Precedents Cited

  • Colburn v. Saykaly, 173 N.H. 162 (2020): Cited for the foundational proposition that a court lacks power to hear matters beyond its subject matter jurisdiction and that subject matter jurisdiction is reviewed de novo. This framed the Supreme Court’s method: the dispute was purely legal—what the statutes authorize—rather than discretionary.
  • In the Matter of Muller & Muller, 164 N.H. 512 (2013): Used to emphasize that the family division’s jurisdiction is “conferred entirely by statute,” requiring the Court to identify the affirmative statutory grant of authority (here, RSA 490-D:2, and by extension RSA 490-F:3).
  • In the Matter of Penichet & Corroon, 177 N.H. 227 (2025): Supplied the Court’s interpretive approach to UIFSA— ordinary statutory construction rules apply. It also supported the Court’s discussion of UIFSA’s long-arm jurisdiction provision (RSA 546-B:3) as the mechanism for obtaining personal jurisdiction over a nonresident in support/paternity matters.
  • In the Matter of Scott & Pierce, 160 N.H. 354 (2010): Served two roles: (1) stating UIFSA’s status as a congressionally encouraged model act adopted nationwide, and (2) articulating interpretive principles—read statutory language in context, do not add language the legislature did not include, and construe provisions to effectuate the statute’s overall purpose.
  • In the Matter of Ball & Ball, 168 N.H. 133 (2015): Supported the Court’s commitment to uniform interpretation of UIFSA, including consulting official comments, later amendments for interpretive insight, and other jurisdictions’ approaches. It also reinforced UIFSA’s core purpose: preventing conflicting support orders across states.

3.2 Legal Reasoning

The opinion proceeds in three statutory steps: (1) identify the trial court’s baseline support jurisdiction, (2) test whether UIFSA removes or limits that jurisdiction in these circumstances, and (3) determine which UIFSA “track” applies—long-arm (“one-state”) versus interstate “responding tribunal” (“two-state”) proceedings.

(a) Baseline jurisdiction exists under New Hampshire’s court-organization statutes.

The Court first anchored subject matter jurisdiction in RSA 490-D:2, which grants the family division exclusive jurisdiction over “support,” and explained that the circuit court holds that authority via RSA 490-F:3. This matters because UIFSA is not treated as an independent source of general support jurisdiction; rather, it is a specialized interstate framework that can govern how jurisdiction is exercised when multiple states are implicated.

(b) RSA 546-B:31’s “responding tribunal” language does not apply when New Hampshire proceeds via long-arm jurisdiction.

The trial court read RSA 546-B:31, I as an exclusive gateway: a New Hampshire “responding tribunal” “may issue” an initial support order only if the requesting individual (or agency) is located outside New Hampshire. The Supreme Court acknowledged that this reading is “plausible” if the provision is read in isolation, but rejected it once UIFSA’s structure and definitions are applied.

UIFSA defines “responding tribunal” and “responding state” in terms of a petition filed (or forwarded for filing) from another state or foreign country. The Supreme Court reasoned that the mother did not initiate a two-state UIFSA process; she initiated a New Hampshire proceeding and obtained personal jurisdiction over a nonresident father through UIFSA’s long-arm jurisdiction provision, RSA 546-B:3.

(c) RSA 546-B:11-a is the controlling provision for long-arm cases and excludes Articles 3–6 (including RSA 546-B:31) in most respects.

The Court’s decisive move was to apply RSA 546-B:11-a. That statute states that when a New Hampshire tribunal exercises personal jurisdiction over a nonresident in a proceeding under UIFSA, it may use certain Article 3 procedures, but “in all other respects, Articles 3 through 6 do not apply,” and the tribunal “shall apply the procedural and substantive law of this state.”

Because RSA 546-B:31 is in Article 4, it is among the provisions that “do not apply” in this posture. Accordingly, the trial court’s reliance on RSA 546-B:31 to deny subject matter jurisdiction was legal error.

The opinion is also notable for its use of UIFSA official comments to confirm the statute’s architecture: satisfying the long-arm statute creates a “one-state proceeding” despite interstate residence, and once personal jurisdiction is secured, the forum applies its own law and issues an order that carries UIFSA consequences (including continuing jurisdiction concepts).

3.3 Impact

  • Corrects a jurisdictional misreading that could routinely block in-state parents from obtaining initial support orders. The trial court’s approach would have produced a counterintuitive and burdensome regime: New Hampshire residents could be forced into two-state “responding tribunal” mechanisms (or out-of-state filing) even when New Hampshire can constitutionally exercise personal jurisdiction. The Supreme Court’s decision prevents that access-to-justice bottleneck.
  • Clarifies UIFSA “tracks” for practitioners and trial courts. The opinion draws a bright operational distinction: long-arm personal jurisdiction (RSA 546-B:3; governed by RSA 546-B:11-a; forum law applies) versus two-state responding tribunal proceedings (where Article 4 establishment provisions like RSA 546-B:31 may matter).
  • Reinforces UIFSA’s purpose without expanding it beyond its role. UIFSA’s anti-conflict objective is preserved: the decision does not invite multiple competing orders; it simply confirms that a state with personal jurisdiction can issue an initial support order in a “one-state” case, consistent with UIFSA’s design and comments.
  • Practical downstream effects. On remand, the circuit court may issue child support and “other support-related orders” (as the Supreme Court described them), likely including income withholding and related enforcement mechanisms under New Hampshire law, without treating RSA 546-B:31 as a jurisdictional bar.

4. Complex Concepts Simplified

  • Subject matter jurisdiction vs. personal jurisdiction: Subject matter jurisdiction is a court’s legal power to decide the type of case (here, child support). Personal jurisdiction is the court’s power over the person. The trial court agreed it had personal jurisdiction over the father but mistakenly believed UIFSA removed subject matter jurisdiction.
  • UIFSA “long-arm” jurisdiction (RSA 546-B:3): A statute allowing New Hampshire to reach a nonresident for support if certain connections exist (e.g., the nonresident lived with the child in New Hampshire). If long-arm grounds are met, New Hampshire can proceed directly against the out-of-state parent.
  • “One-state” vs. “two-state” UIFSA proceedings: A “one-state” case occurs when New Hampshire obtains personal jurisdiction over the nonresident parent and litigates in New Hampshire. A “two-state” case typically involves a petition sent from one state to another, making the second state a “responding state/tribunal.”
  • “Responding tribunal” (RSA 546-B:1, XXIV) and “responding state” (RSA 546-B:1, XXIII): These terms are tied to interstate forwarding/filing mechanics. They are not triggered merely because one party lives elsewhere.
  • Why RSA 546-B:11-a matters: It is a routing provision: once New Hampshire asserts personal jurisdiction over the nonresident, it largely exits Articles 3–6 and applies forum law, preventing misapplication of provisions designed for interstate “responding tribunal” workflows.

5. Conclusion

In the Matter of Stansfield & Patti establishes a clear rule for New Hampshire support practice under UIFSA: when a New Hampshire tribunal has personal jurisdiction over a nonresident parent under UIFSA’s long-arm provision, the case is a “one-state proceeding,” RSA 546-B:11-a directs the application of New Hampshire law, and Article 4’s establishment limitation in RSA 546-B:31 does not deprive the court of authority to set child support or enter related support orders.

The decision strengthens uniform, purpose-driven UIFSA interpretation, prevents an unduly restrictive jurisdictional barrier for in-state families, and provides a practical roadmap for courts and litigants navigating interstate residence in child support establishment proceedings.
