Montana Supreme Court

Matters of L.c., X.p. & N.c., Yinc

June 2, 20262026 MT 121

Summary

The Court affirmed the termination of Mother's parental rights, holding that the District Court did not clearly err in finding that the Department made diligent efforts to determine whether the children were Indian children under ICWA. The Department investigated the children's potential tribal affiliations, provided relevant information to the Blackfeet Tribe, and received verification that the children were not enrolled or eligible for enrollment. The Court also held that, even if the Department's efforts were arguably insufficient, Mother waived the challenge by failing to object or present additional information below.
