Background
In February 2023, Montana’s Department of Public Health and Human Services, Child and Family Services Division, filed petitions in Cascade County to have three children—L.C., X.P., and N.C.—adjudicated as youths in need of care. The children share the same mother, C.C. (Mother), but have different putative fathers. Because prior Department history indicated that X.P.’s putative father, M.P., may have been affiliated with the Blackfeet Tribe, the Department treated X.P. as potentially subject to the Indian Child Welfare Act (ICWA). For L.C. and N.C., whose putative father D.A. was reported deceased with no known tribal affiliation, the Department found no initial reason to believe ICWA applied.
To discharge its ICWA obligations, the Department gathered heritage information from Mother, completed ICWA checklist forms, and sent verification requests to the Blackfeet Tribe by certified mail. The Tribe responded in early February 2023, confirming that none of the three children were enrolled or eligible for enrollment. The District Court repeatedly found throughout the proceedings—across orders issued from March 2023 through December 2024—that the Department had made diligent efforts to determine ICWA applicability and that the children were not Indian children. Mother’s counsel agreed at the April 2023 show cause hearing that the Department’s ICWA qualified expert witness need not testify, and Mother never objected to or challenged any of the court’s ICWA determinations during the proceedings below.
The District Court terminated Mother’s parental rights on September 2, 2025, under § 41-3-609(1)(f), MCA, finding the children had been adjudicated youths in need of care, Mother had not successfully completed her court-approved treatment plan, and the conditions rendering her unfit were unlikely to change within a reasonable time. Mother did not challenge the termination grounds on appeal; her sole argument was that the Department failed to make diligent efforts to determine ICWA’s applicability.
The Court’s Holding
The Montana Supreme Court unanimously affirmed, holding that the District Court’s finding of diligent ICWA inquiry was not clearly erroneous on the record presented. With respect to X.P., the Court found that the Department’s prior history with the child gave it a cognizable “reason to know” X.P. might be an Indian child, and the Department responded appropriately—completing ICWA checklists, sending a verification request, and serving the Blackfeet Tribe with a notice of hearing identifying M.P. by name. The Tribe’s unrevised response certifying X.P. was neither enrolled nor enrollable was conclusive, as tribal eligibility is a question of fact exclusively for the tribe to determine under 25 C.F.R. § 23.108(b).
As to L.C. and N.C., the Court found no “reason to know” those children were Indian children from the outset. D.A. had never been established as their biological father—he was only a putative father—and a putative father’s tribal affiliation cannot support Indian-child status under ICWA’s definition, which requires the child to be the biological child of a tribal member. Accordingly, even accounting for a typographical error in the spelling of D.A.’s name on the verification request, the Department was under no obligation to seek additional verification once the error was discovered, because D.A.’s tribal status was legally irrelevant.
The Court also held that, even if the Department’s inquiry had been arguably deficient, Mother waived the objection by acquiescing throughout the proceedings. She agreed at the show cause hearing that ICWA did not apply, never presented evidence suggesting the children were Indian children, and raised the issue for the first time on appeal. The Court emphasized that ICWA is not a procedural tool to be invoked as a technicality when a parent does not genuinely believe her children are Indian children.
Key Takeaways
- A tribe’s unrevised written determination that a child is neither enrolled nor eligible for enrollment is conclusive proof that ICWA does not apply; the tribe is the sole arbiter of membership eligibility under 25 C.F.R. § 23.108(b).
- A putative (unestablished) father’s tribal affiliation cannot form the basis for Indian-child status under ICWA because the statute requires the child to be the biological child of a tribal member; paternity must be legally established.
- A parent who agrees during proceedings that ICWA does not apply, never objects to the court’s repeated ICWA findings, and presents no contrary evidence waives any ICWA diligence challenge on appeal.
- Minor investigative imperfections—such as a misspelled name in a verification request or a verification letter issued before a notice of hearing was received—do not render a Department’s ICWA inquiry non-diligent where no information in the record actually suggested Indian ancestry.
Why It Matters
This decision clarifies the interplay between a state agency’s ICWA due-diligence duty and the preservation requirements that govern appellate review in Montana termination proceedings. Practitioners should note that the Court treated a tribe’s unrebutted eligibility denial as conclusive and declined to impose a duty on the Department to re-contact the tribe simply because a notice of hearing arrived after the initial verification response. The opinion signals that procedural ICWA arguments will receive little traction when a parent has conceded non-applicability at the trial level and presented no evidence—even circumstantial—that the children have Indian ancestry.
The Court’s waiver analysis also carries practical weight: it underscores that ICWA’s protections, while robust, are not self-executing shields against termination when a parent strategically raises them for the first time on appeal without any genuine claim of Indian heritage. Child welfare agencies and courts should nonetheless document ICWA inquiry efforts meticulously at each stage, as the opinion’s favorable outcome for the Department rested heavily on the detailed factual record of its outreach to the Blackfeet Tribe.
