Background
The Montana Department of Public Health and Human Services, Child and Family Services Division (Department), filed petitions in February 2023 to have three children—L.C., X.P., and N.C.—adjudicated as youths in need of care (YINC) in Cascade County District Court. The petitions reflected different factual circumstances regarding potential Indian child status. For L.C. and N.C., the Department stated it had no reason to know they were “Indian children” under the Indian Child Welfare Act (ICWA), 25 U.S.C. §§ 1901 et seq., because their putative father, D.A., was listed as deceased and no tribal affiliation was identified. For X.P., the Department had prior history indicating that X.P.’s father, M.P., might be affiliated with the Blackfeet Tribe, so the Department asserted that X.P. may be an Indian child.
To investigate ICWA applicability, the Department completed ICWA checklists, obtained information from the mother (C.C.) about the children’s heritage, and sent a verification request to the Blackfeet Tribe. It also sent the Tribe a formal Notice of Hearing by certified mail, identifying X.P.’s name and birthdate, the mother’s name and address, M.P.’s name and address, and the Department’s belief that X.P. may be enrolled or enrollable. The Blackfeet Tribe responded in February 2023 confirming that none of the three children were enrolled or enrollable in the Tribe. For L.C. and N.C., the Tribe’s verification letter reflected D.A.’s name with a typographical error (“d” vs. “t” at the end of his surname).
The District Court repeatedly found at hearings throughout the case that the Department had made diligent ICWA efforts and that ICWA did not apply, and ordered the parties to notify the court if they learned the children might be Indian children. Mother’s own counsel acknowledged the Tribe’s letters at the show cause hearing and agreed the Department’s ICWA qualified expert witness need not testify. Mother never objected to the ICWA determinations, never presented evidence that any of the children were Indian children, and never filed any notice claiming tribal affiliation. At a March 2025 hearing, the Department disclosed the typographical error in D.A.’s name; Mother made no objection and raised no ICWA challenge at that time. In September 2025, the District Court terminated Mother’s parental rights under § 41-3-609(1)(f), MCA, after finding she failed to complete her court-approved treatment plan. Mother appealed, challenging only the ICWA diligence finding.
The Court’s Holding
The Montana Supreme Court affirmed. Justice Gustafson’s opinion addressed the ICWA diligence question for each child in turn and added an independent waiver holding that applied to all three.
As to X.P., the Court held that the District Court’s finding was not clearly erroneous. Although the Tribe’s verification letter arrived before the Department’s Notice of Hearing could have been received and processed, the Department sent the Tribe both the verification request and the Notice of Hearing with M.P.’s identifying information. After the Tribe received both sets of documents, it never revised or supplemented its verification that X.P. was not enrolled or enrollable. Under 25 C.F.R. § 23.108(b), tribal eligibility determinations are for the tribe exclusively, and a verification letter that is never revised becomes conclusive proof that the child is not an Indian child subject to ICWA.
As to L.C. and N.C., the Court held that the typographical error in D.A.’s name was immaterial because D.A. was never established to be their biological father—he was identified only as a putative father with no completed paternity testing. ICWA’s definition of “Indian child” covers a minor who is a member of a tribe or who is eligible for membership and “is the biological child of a member.” 25 U.S.C. § 1903(4). A putative father who has not been established through paternity testing cannot satisfy the biological-child requirement, so any error in identifying D.A.’s tribal status would not have established L.C. or N.C. as Indian children.
Finally, the Court held that even if the Department’s efforts were arguably not diligent, Mother waived the argument by failing to object below. Mother agreed at the show cause hearing that the ICWA qualified expert need not testify, agreed to notify the court if new information emerged, raised no challenge when the typographical error was disclosed, and never presented any evidence or claim that any of the children were Indian children. The Court emphasized that ICWA “is not intended to be invoked as a procedural technicality to delay and contest termination of parental rights when a parent does not genuinely believe her children are Indian children.”
Key Takeaways
- A tribal verification letter confirming non-enrollment that is never revised after the tribe receives complete identifying information is conclusive proof that a child is not an Indian child under ICWA, per 25 C.F.R. § 23.108(b); the tribe’s exclusive authority to determine membership means a Department error in the initial request does not automatically nullify a valid verification.
- ICWA’s “Indian child” definition at 25 U.S.C. § 1903(4) requires that the child be the biological child of a tribal member; a putative father whose paternity has not been established cannot provide the basis for ICWA applicability, making any typographical error in his tribal identification legally irrelevant.
- A parent who actively agrees with ICWA diligence determinations at multiple hearings, waives expert testimony on the question, and never presents evidence or claims that the children are Indian children, acquiesces in those determinations and waives the right to challenge them on appeal.
- ICWA is a substantive protection for Indian children and tribes, not a procedural mechanism for delaying termination of parental rights; courts should be attentive to whether ICWA arguments on appeal are genuine substantive claims or tactical challenges by a parent who has never actually asserted that the children are Indian children.
Why It Matters
Montana has a significant ICWA caseload given the presence of federally recognized tribes—including the Blackfeet, Crow, Cheyenne, Salish, and others—and the state’s child welfare system regularly encounters cases requiring ICWA analysis. In re Matters of L.C., X.P. & N.C. provides several important clarifications for that practice. First, it confirms that a complete, unrebutted tribal verification letter is conclusive on the membership question: the tribe has spoken, and absent new information that the tribe has had a chance to consider and has revised its determination, the verification stands. Second, it draws a clear distinction between a biological father (who can establish ICWA eligibility) and a putative father (who cannot), making it important for practitioners and CPS workers to understand that tribal-affiliation inquiries need not be pursued with respect to an unestablished putative father.
The acquiescence holding is equally significant. The Court’s framing—that ICWA should not be used as a “procedural technicality” by a parent who does not genuinely believe her children are Indian children—signals that last-minute ICWA challenges raised for the first time on appeal, without any record-level assertion that the children are tribal members or members of a family with tribal affiliation, will face substantial waiver hurdles. Practitioners representing parents in TPR cases should ensure that any genuine ICWA concerns are raised promptly at the trial level, both to preserve the issue and to allow the Department to supplement its investigation if warranted.
