(d) In the case of an Indian child who is not a ward of a tribal court or subject to the exclusive jurisdiction of an Indian tribe, as described in subdivision (b), the state court shall transfer the proceeding to the jurisdiction of the child’s tribe upon petition of either parent, the Indian custodian, or the child’s tribe, unless the state court finds good cause not to transfer. The petition for transfer may be made orally on the record or in writing at any stage of the proceedings. Upon receipt of a petition for transfer, the state court shall terminate jurisdiction only after receiving confirmation that the tribal court has accepted the transfer. At the time that the state court terminates jurisdiction, the state court shall also do both of the following:

1. (1) Expeditiously provide the tribal court with all records related to the proceeding, including, but not limited to, the pleadings and any state court record.
2. (2) Work with the tribal court to ensure that the transfer of the child and of the proceeding is accomplished smoothly and in a way that minimizes the disruption of services to the family.

(e)

1. (1) If a petition to transfer proceedings as described in subdivision (d) is made orally on the record or in writing, the state court shall find good cause to deny the petition if either of the following circumstances are shown to exist:

   1. (A) One or both of the child’s parents object to the transfer.
   2. (B) The tribal court of the child’s tribe declines the transfer.

2. (2) In determining whether good cause exists to deny a transfer, the state court shall not consider any of the following:

   1. (A) Socioeconomic conditions and the perceived adequacy of tribal social services or judicial systems.
   2. (B) Whether the child custody proceeding is at an advanced stage if the Indian child’s parent, Indian custodian, or tribe did not receive notice of the child custody proceeding until an advanced stage. It shall not, in and of itself, be considered an unreasonable delay for a party to wait until reunification efforts have failed and reunification services have been terminated before filing a petition to transfer.
   3. (C) Whether there have been prior proceedings involving the child for which no transfer petition was filed.
   4. (D) Whether the transfer could affect the placement of the child.
   5. (E) Whether the Indian child has cultural connections with the tribe or its reservation.
3. (3) The burden of establishing good cause not to transfer shall be on the party opposing the transfer. If the state court believes, or any party asserts, that good cause not to transfer exists, the reasons for that belief or assertion shall be stated orally on the record or in writing and made available to all parties who are petitioning for the transfer, and the petitioner shall have the opportunity to provide information or evidence in rebuttal of the belief or assertion.
4. (4) This section and Sections 1911 and 1918 of Title 25 of the United States Code shall not be construed as requiring a tribe to petition the Secretary of the Interior to reassume exclusive jurisdiction pursuant to Section 1918 of Title 25 of the United States Code prior to exercising jurisdiction over a proceeding transferred under subdivision (d).
