My baby daddy has claimed our kid is not his from the start. he recently started saying that he plans on taking me to court on the reservation once the child is born even though I don’t live on the rez and the child will live with me. can he do that?
1. yes. he is a tribe member. 2. no.
Attorney Answer
He likely cannot simply force the case into tribal court based on his tribal membership alone — jurisdiction generally follows where the child and the custodial parent live, not a parent's tribal affiliation — but this is necessarily a preliminary answer, since the child isn't born yet, paternity hasn't been established, and tribal-state jurisdictional rules vary by tribe and can be genuinely unsettled.
Custody jurisdiction typically depends on the residence of the child and the parent with custody, so if you and the baby will live off the reservation, that generally weighs against tribal court having authority over the case. That said, the specific tribe's own code, together with applicable state law, controls how tribal and state jurisdiction interact, and those rules aren't uniform across tribes, so this can't be answered with full certainty in the abstract. Separately, since paternity hasn't yet been legally established, that will likely need to be resolved as an early step in any custody matter regardless of which court ends up hearing it, and until it's established, the broader custody analysis remains preliminary.
What you can do:
1. Prepare to establish paternity as a first step once the child is born, since that affects which court has authority.
2. Look into the specific tribe's court code regarding jurisdiction over children living off the reservation.
3. Keep records showing where you and the child will reside after birth.
4. Consult a family law attorney experienced in tribal-state jurisdiction overlap, since this raises questions a general family law matter wouldn't.
Relevant Case Law
Mitchell v. Preston, 439 P.3d 718 (2019) — Wyoming Supreme Court
An Indian tribe shall have jurisdiction exclusive as to any State over any child custody proceeding involving an Indian child who resides or is domiciled within the reservation of such tribe, except where such jurisdiction is otherwise vested in the State by existing Federal law.
Under this federal rule, a tribe's exclusive custody jurisdiction generally depends on the child living on the reservation, so an off-reservation home usually keeps the case in state court.

Frequently Asked Questions
Does a parent's tribal membership alone determine which court hears a custody case?
Generally not by itself. Custody jurisdiction typically depends on where the child and custodial parent reside, though the specific tribe's code and applicable state law can affect how jurisdiction is determined.
Can a custody case be filed before a child is born?
No, generally courts cannot address custody of a child who has not yet been born, so this issue would need to wait until after birth.
Does paternity need to be established before a custody case can proceed?
Yes, in many cases legal paternity must be established first, since custody rights and obligations generally depend on legally recognized parentage.
