 In these concurrent decisions, the ICWA expresses a preference for tribal jurisdiction in Indian child custody proceedings.In an involuntary proceeding, the party seeking the placement of the child, which is often but not always the state, must notify both the parent(s) and/or Indian custodian(s) and the child's tribe at least 10 days prior to the proceeding.Emergency proceedings may follow state law, but proceedings after that are controlled by ICWA.
