Okla. Admin. Code § 340:75-19-5 - Tribal and state court jurisdiction
Tribal courts have exclusive jurisdiction over any child custody proceeding involving an Indian child who resides within the reservation of such tribe. The tribal court shares concurrent jurisdiction with the state court in state court proceedings for foster care placement of, or termination of parental rights to, an Indian child not residing within the reservation of the Indian child's tribe. The tribe, either parent, or an Indian custodian may request transfer of state court proceedings to tribal court.
