The purpose of the Nebraska Indian Child Welfare Act is to clarify state policies and procedures regarding the implementation by the State of Nebraska of the federal Indian Child Welfare Act. It shall be the policy of the state to cooperate fully with Indian tribes in Nebraska in order to ensure that the intent and provisions of the federal Indian Child Welfare Act are enforced. This cooperation includes recognition by the state that Indian tribes have a continuing and compelling governmental interest in an Indian child whether or not the Indian child is in the physical or legal custody of a parent, an Indian custodian, or an Indian extended family member at the commencement of an Indian child custody proceeding or the Indian child has resided or is domiciled on an Indian reservation. The state is committed to protecting the essential tribal relations and best interests of an Indian child by promoting practices consistent with the federal Indian Child Welfare Act and other applicable law designed to prevent the Indian child’s voluntary or involuntary out-of-home placement.
