What are the criteria for ruling on transfer petitions?

Upon receipt of a transfer petition from an Indian child's parent, Indian custodian, or Tribe, the State court must transfer the child-custody proceeding unless the court determines that transfer is not appropriate because one or more of the following criteria are met: (a) Either parent objects to such transfer; (b) The Tribal court declines the transfer; or (c) Good cause exists for denying the transfer.
