While it looks like the State gave notice to Cherokee Nation and Blackfeet Tribe with all the information on the record, and it’s also good the State noticed local Michigan tribes (State is required to contact a tribe in the county where the child is located under 712B.9(3)), the original notice to *all* of the tribes should be in the record. And noticing UKB when a parent claims Cherokee is not something above and beyond, but what the State is supposed to do (along with CNO and Eastern Band):

In addition to the above notifications, the lower court record contains evidence of additional efforts made by DHS to ascertain whether RI and KI had Indian heritage. Specifically, the record contains a response from the United Keetowah Band of Cherokee Indians in Oklahoma indicating that neither RI nor KI were members, although the lower court record does not contain the original notification sent to that tribe. Additionally, the record contains responses from the Saginaw Chippewa Indian Tribe of Michigan indicating that neither RI nor KI were members or eligible for membership, although the lower court record again does not contain the original notifications sent to that tribe. Finally, the record contains copies of both the notifications to, and a response from, the Nottawaseppi Huron Band of Potawatomi Indians; membership in that tribe was also denied. In addition to the above record evidence, DHS reports indicate that notifications were sent to a plethora of other tribes, and that membership in those tribes was denied.

The Michigan COA interpreted In re Morris to require a conditional reversal when the parent asserted that his grandmothers were Native and:

It is unclear from the record exactly how or why the caseworker came to the conclusion, reflected in the case service plans, that the minor child is not an Indian child for purposes of 25 USC 1912(a); some elaboration would have been appropriate given the father’s assertion. There is no indication that an inquiry or investigation was made specifically with respect to the father’s claim made at the preliminary hearing, nor an explanation in regard to why the father’s claim was being discounted, assuming it was evaluated or pondered in the first place, such that the ICWA notice requirement was not triggered. Of special concern to us is that the initial case service plan, in its summarization of the trial court’s preliminary hearing order, made no mention of the court’s command that the caseworker “make necessary inquiry and/or notification as to possible Native American Indian heritage.” Furthermore, there is no clear confirmation by the court itself that its initial concerns of whether the child is an Indian child were alleviated. Moreover, the father’s assertion concerning the Native American heritage of the minor child’s paternal great-grandparents fits within the parameters of the examples given by the Morris Court, quoted above, that would trigger the need to serve notice. Morris, 491 Mich at 108 n 18. Finally, petitioner itself concedes that conditional reversal is necessary in order to determine whether the minor child is an Indian child under the law.
