Yes. The state will enforce a tribal order. State and tribal child support agencies are required to recognize and enforce the child support orders issued by the other jurisdiction.
If the noncustodial parent still lives on the reservation, the tribe will continue to enforce the order. If the noncustodial parent moves off the reservation, the tribe may ask the state for assistance in enforcing the order. If the noncustodial parent met the obligation with in-kind payments and the state is helping to enforce the order, the noncustodial parent will now pay the order in cash rather than in-kind, non-cash payments.
