Based on the difficulties CYFD experienced in receiving evidence on Mother’s lineage and the Navajo Nation’s determination that Children are ineligible, we hold that Children are not eligible for enrollment with the Navajo Nation. Nevertheless, Father asserts that the status of Children does not need to be certain to implement the ICWA and the district court must only examine whether the ICWA possibly applies, relying on In re Desiree F., 99 Cal. Rptr. 2d 688 (Ct. App. 2000). We conclude that Desiree F. does not assist Father.
