Concurrent Tribal–State Custody Disputes: Alaska Adopts a “First-to-File” Preferred Forum Rule and Requires Exhaustion of Tribal Jurisdictional Remedies

1. Introduction

Sarah Rachel Mallette v. Garfield Tau Adams (consolidated with Garfield Tau Adams v. Sarah Rachel Mallette) presented the Alaska Supreme Court with a recurring inter-sovereign family-law problem: when both a tribal court and the Alaska Superior Court have concurrent authority to decide a child custody dispute involving a tribal-eligible child, which court should proceed when parallel filings occur?

The parties are unmarried parents. The father, Garfield Tau Adams, is a member of the Kenaitze Indian Tribe, and the child is eligible for tribal membership. The mother, Sarah Rachel Mallette, is not tribally affiliated and contested the Kenaitze Tribal Court’s personal jurisdiction over her.

The key issues were (1) whether the superior court properly dismissed the later-filed state custody case in favor of earlier tribal proceedings; (2) whether the mother could litigate personal jurisdiction in state court without first pursuing tribal remedies; and (3) whether a stay pending appeal was proper (raised by cross-appeal).

2. Summary of the Opinion

The Alaska Supreme Court affirmed dismissal of the state custody case and held that, where the same custody matter is filed in both tribal and state court, the tribunal in which the custody matter is filed first is the “preferred forum” to proceed “in the first instance.” Because Adams filed his second non-emergency custody petition in Kenaitze Tribal Court before Mallette filed her state custody complaint, the superior court correctly declined to exercise jurisdiction while tribal proceedings were pending.

The Court also held that Mallette must raise and exhaust her personal-jurisdiction challenge in tribal court before asking a state court to deny comity to a resulting tribal order. The Court did not decide the proper substantive standard for tribal personal jurisdiction (including whether International Shoe “minimum contacts” applies) because the record was not developed and the tribal court had not ruled on its jurisdiction.

Finally, the Court held the stay dispute was moot because the Court had already vacated the stay in an earlier order. It nevertheless cautioned that the superior court lacked jurisdiction to modify the stay while it was on appeal.

3. Analysis

A. Precedents Cited

  • John v. Baker (John I), 982 P.2d 738 (Alaska 1999)
    • Foundation for the case: Alaska Native tribes possess “inherent, non-territorial sovereignty” to resolve domestic disputes involving their members, and Alaska courts should respect tribal judgments under comity while withholding enforcement where jurisdiction is lacking.
    • The Court relied on John I for both (a) the baseline authority for tribal adjudication in domestic matters and (b) the comity framework later applied after a tribal order exists.
  • John v. Baker (John II), 30 P.3d 68 (Alaska 2001)
    • Key support for prioritizing the first forum and for the Court’s concern with record development for later review.
    • The Court quoted John II to underscore that the forum first seised should be treated as “the preferred forum” in the first instance, and reiterated John II’s warning that an undeveloped record can make comity review impracticable.
    • The Court also drew from John II in explaining that Alaska has “previously declined to adopt a strict exhaustion requirement” in custody cases, while still endorsing exhaustion where tribal jurisdiction is “colorable and plausible.”
  • Starr v. George, 175 P.3d 50 (Alaska 2008)
    • Confirmed that “custody disputes between unmarried parents” are exempt from ICWA’s definition of a “child custody proceeding.” This mattered because Mallette’s ICWA-based jurisdictional argument could not supply an exclusive-jurisdiction rule favoring tribal court; instead, the analysis proceeded on concurrent jurisdiction principles.
  • Simmonds v. Parks, 329 P.3d 995 (Alaska 2014)
    • Provided the standard of review (de novo) for the extent of tribal court jurisdiction.
    • Substantively supported the Court’s approach to exhaustion: even when strict exhaustion is not mandatory in every custody context, the policies behind exhaustion require tribal courts be allowed to decide jurisdiction first where it is “colorable and plausible.”
  • State v. Cent. Council of Tlingit & Haida Indian Tribes of Alaska, 371 P.3d 255 (Alaska 2016)
    • Reinforced the Court’s insistence on a “concrete factual record” and a full opportunity to develop factual and legal arguments before a state court attempts to resolve personal-jurisdiction questions in this setting.
  • International Shoe Co. v. Washington, 326 U.S. 310 (1945)
    • Raised by Mallette as the relevant personal-jurisdiction standard (“minimum contacts”). The Court did not adopt or reject that framework here, holding instead that the tribal court must address its own jurisdiction first.
  • Preservation/waiver line of cases:
    • Brandon v. Corr. Corp. of Am., 28 P.3d 269 (Alaska 2001)
    • Numann v. Gallant, 555 P.3d 527 (Alaska 2024)
    • Rivera v. State, Dep't of Admin., Div. of Motor Vehicles, 564 P.3d 1040 (Alaska 2025)

    These authorities supported the Court’s holding that Mallette waived the argument that her earlier DVPO filings should control jurisdictional priority because she did not meaningfully develop that argument in the superior court.

  • Stay/mootness and appellate jurisdiction authorities:
    • Rosalind M. v. State, Dep't of Fam. & Cmty. Servs., Off. of Child.'s Servs., 555 P.3d 505 (Alaska 2024) (stay standard and the propriety of a short stay to permit appellate review)
    • Alsworth v. Seybert, 323 P.3d 47 (Alaska 2014) (quoted within Rosalind M.)
    • Armstrong v. Tanaka, 228 P.3d 79 (Alaska 2010) and Clemensen v. Providence Alaska Med. Ctr., 203 P.3d 1148 (Alaska 2009) (abuse-of-discretion review for stays)
    • J.P. v. State, 506 P.3d 3 (Alaska 2022) (mootness)
    • Asher v. Alkan Shelter, LLC, 212 P.3d 772 (Alaska 2009) (trial court cannot modify matters on appeal)
    • Heppinstall v. Darnall Kemna & Co., 851 P.2d 78 (Alaska 1993) (quoted in Asher)
    • Shaffer v. Bellows, 260 P.3d 1064 (Alaska 2011) (noted as abrogating Asher on other grounds)

    These cases framed the Court’s resolution of the cross-appeal as moot and its admonition that the superior court lacked jurisdiction to alter a stay order once appealed (also anchored in Alaska R. App. P. 203).

B. Legal Reasoning

1. The new “first-to-file” preferred forum rule for concurrent tribal–state custody proceedings

The Court started from the established proposition that, in ICWA-exempt custody disputes involving tribal-eligible children, tribal and state courts generally possess concurrent jurisdiction and neither enjoys “priority, or presumptive authority.” Rather than leave parallel-filing conflicts to ad hoc discretion, the Court “clarif[ied]” a rule: when both systems are invoked for “the same custody matter,” the court where the matter is first filed should be treated as the “preferred forum” to resolve the dispute “in the first instance.”

The Court analogized—carefully, as “illustrative” rather than controlling—to Alaska’s UCCJEA approach to simultaneous interstate custody proceedings, citing AS 25.30.350(a). The principle is familiar: if another competent court has already commenced a custody proceeding, Alaska courts generally must refrain from exercising jurisdiction while that proceeding remains pending (subject to statutory exceptions in the interstate context, such as emergency jurisdiction). The Court transplanted this logic to the tribal–state concurrency setting as a matter of Alaska common law and policy supporting orderly administration of justice and avoidance of conflicting custody orders.

Applying the rule was straightforward on the Court’s view: Adams’s second tribal custody petition was filed before Mallette’s state custody complaint. That sequencing controlled, making the tribal court the proper forum at the outset and requiring dismissal (or non-exercise) by the superior court while tribal proceedings remained pending.

2. Waiver of the DVPO-based sequencing argument

Mallette attempted to avoid the first-to-file outcome by reframing the relevant “first filing” as her earlier state DVPO petition (filed after Adams withdrew his first tribal petition but before his second tribal custody petition). The Court held this theory was waived because it was mentioned only as background and not presented as a developed legal argument in the superior court proceedings. Under Brandon v. Corr. Corp. of Am., Numann v. Gallant, and Rivera v. State, Dep't of Admin., Div. of Motor Vehicles, such cursory references do not preserve an issue for appellate review.

3. “Exercise of jurisdiction” vs. “date of filing” (and harmless error)

The superior court had pointed to a June 17 tribal court hearing as evidence the tribal court had “already exercised” jurisdiction before Mallette filed in state court. On appeal, Mallette argued the record was too thin to support that factual finding. The Supreme Court effectively sidestepped the dispute: even if the superior court erred in finding the tribal court had already “exercised” jurisdiction on June 17, any error was harmless because the controlling event is the date the custody action is filed, not the depth of early proceedings.

4. Exhaustion of tribal remedies for personal-jurisdiction challenges

Mallette also argued the Kenaitze Tribal Court lacked personal jurisdiction over her, urging application of International Shoe Co. v. Washington and its “minimum contacts” framework. Adams argued tribal jurisdiction arose under the tribal code’s provision extending jurisdiction over persons entering “consensual relations with the Tribe or tribal members.”

The Court did not decide which substantive personal-jurisdiction standard governs. Instead, it enforced a sequencing principle grounded in respect for tribal sovereignty and sound adjudication: because the record was not developed and the tribal court had not ruled on jurisdiction, the tribal court must have the first opportunity to determine its own jurisdiction, and Mallette must exhaust available tribal remedies before returning to state court to contest enforcement under comity.

While reiterating that Alaska has “previously declined to adopt a strict exhaustion requirement” for custody cases (John v. Baker (John II)), the Court emphasized that exhaustion is still required where tribal jurisdiction is “colorable and plausible” (Simmonds v. Parks). The Court also noted the availability of “robust appellate procedures” within the Kenaitze Tribal Court system, strengthening the case for exhaustion. Only after the tribal process runs its course may a party seek state-court review in the posture the Court envisioned: a comity challenge to a concrete tribal order, on a record suitable for review (John v. Baker (John I); John v. Baker (John II)).

5. The stay dispute: mootness, limited guidance, and appellate control

Adams cross-appealed the superior court’s stay of the dismissal order pending appeal. The Supreme Court held the issue moot because it had already vacated the stay in a prior order and thus no further relief was available (J.P. v. State).

Even while dismissing the cross-appeal as moot, the Court provided two important procedural clarifications:

  • A superior court may issue a short, temporary stay “long enough” to permit a party to file an appeal and seek a stay from the Supreme Court, reflecting the tension between preserving appellate review and promptly resolving custody disputes (Rosalind M. v. State, Dep't of Fam. & Cmty. Servs., Off. of Child.'s Servs.).
  • The superior court should not modify a stay order that is itself on appeal; once the notice of appeal is filed, “supervision and control” lies in the appellate court under Alaska R. App. P. 203, consistent with Asher v. Alkan Shelter, LLC.

C. Impact

  1. Reduced forum shopping and conflicting orders. The “first-to-file” preferred forum rule supplies a predictable tie-breaker when parents race to competing forums, thereby reducing the risk of inconsistent custody determinations and associated enforcement conflicts.
  2. Stronger functional deference to tribal courts in concurrent-jurisdiction cases. While reaffirming that neither system has inherent priority, the rule ensures the first court seised—often tribal court when a tribal parent files promptly—proceeds without duplicative state litigation running in parallel.
  3. Reinforced exhaustion sequencing for jurisdictional objections. By requiring exhaustion where tribal jurisdiction is “colorable and plausible,” the Court channels personal-jurisdiction disputes into tribal courts first, allowing development of a record and internal appellate review before state comity litigation.
  4. Practical pressure on recordkeeping and reasoned rulings. The Court’s reliance on comity review after tribal orders, coupled with its reminder that absent a “suitably developed record” comity analysis may be impossible (John v. Baker (John II)), incentivizes tribal courts (and litigants) to create clear jurisdictional findings and maintain reviewable records.
  5. Clarified appellate procedure in inter-sovereign custody disputes. The Court’s discussion of temporary stays and appellate control under Alaska R. App. P. 203 provides guidance to trial courts managing time-sensitive custody cases that implicate tribal proceedings.

4. Complex Concepts Simplified

Concurrent jurisdiction
More than one court system has authority to hear the same kind of case. Here, both the Kenaitze Tribal Court and the Alaska Superior Court can potentially decide custody, even though ICWA does not confer exclusive tribal jurisdiction in this unmarried-parent dispute.
“First-to-file” preferred forum
If the same custody dispute is filed in both systems, the one filed first should proceed first. The other court should generally step back while the first case is pending.
Personal jurisdiction
A court’s power over a particular person. Mallette argued the tribal court lacked this power over her as a nonmember. The Supreme Court did not decide the merits; it required the tribal court to decide first.
Exhaustion of tribal remedies
Before asking a state court to intervene on a jurisdictional question, a party generally must use the tribal court’s own procedures—motions, hearings, and tribal appeals—to challenge jurisdiction, so the tribal court can address the issue and build a record.
Comity
A doctrine under which Alaska courts may recognize and enforce tribal court orders out of respect, provided the tribal court had proper jurisdiction and followed basic fairness. The Supreme Court emphasized that comity review typically occurs after a tribal order exists.
Mootness
Courts do not decide issues when a decision can no longer provide meaningful relief. The stay dispute was moot because the Supreme Court had already vacated the stay.
Stay pending appeal
A temporary pause of a trial court order while an appeal is considered. The Court suggested a short stay may be appropriate to preserve the right to seek appellate review, even if a longer stay is not justified.

5. Conclusion

This decision significantly clarifies Alaska law governing simultaneous tribal–state custody filings in ICWA-exempt disputes: the tribunal first seised is the “preferred forum” to proceed in the first instance, and the later-filed court should generally decline to exercise jurisdiction while the first-filed case remains pending. Equally important, the Court reinforced that personal-jurisdiction objections must be litigated through tribal procedures first—so long as tribal jurisdiction is “colorable and plausible”—with state-court review typically occurring later through comity analysis of a concrete tribal order on a developed record.
