Texas Custody for Unmarried Parents: Paternity, Rights, and How to Establish Custody

If you're not married to your child's other parent, custody is established through parentage and a SAPCR rather than a divorce decree. An unmarried father does not obtain an enforceable custody or possession schedule merely from involvement or an AOP; a court order is needed to set those terms. Here's how to establish them.

The Legal Starting Point

When a child is born to unmarried parents and no custody order is in place:

• There may be no court-ordered possession schedule to enforce. Parentage and an enforceable allocation of conservatorship, possession, and decision-making are separate issues.
• An alleged father may need to establish legal parentage before seeking a court order addressing conservatorship and possession.

Signing an Acknowledgment of Paternity (AOP) at the hospital establishes the legal parent-child relationship, but it does not automatically create custody or possession rights. To get those, you need a court order.

How to Establish Paternity

There are two paths:

1. Acknowledgment of Paternity (AOP). Both parents sign this voluntary form, typically at the hospital after birth. It can also be signed later through the Office of the Attorney General. An AOP establishes legal fatherhood, but it does not establish custody or a possession schedule; support and custody terms still need to be addressed through the appropriate proceeding.

2. Court-ordered paternity. If the mother disputes paternity or the father didn't sign an AOP, either parent (or the Attorney General's office) can file a petition to adjudicate parentage. The court will order DNA testing if necessary. Once paternity is established by court order, the father can then seek conservatorship and possession.

Filing for Custody as an Unmarried Parent

Once paternity is established, either parent can file a Suit Affecting the Parent-Child Relationship (SAPCR) — the same type of case used in divorce custody disputes. The process is identical:

1. File the SAPCR petition in the county where the child has resided for the past 90 days, subject to jurisdictional rules
2. Serve the other parent
3. Attend a temporary orders hearing if immediate arrangements are needed
4. Attempt mediation
5. Proceed to trial if mediation fails
6. The court enters a final order establishing conservatorship, possession, and child support

The same best-interest-of-the-child standard applies. The same Holley v. Adams factors are evaluated. The same possession schedule options — Standard Possession Order, Expanded Standard Possession Order, or customized schedules — are available.

What Rights Does an Unmarried Father Have?

After paternity is established and a court order is entered, an unmarried father has the same potential rights as a married one:

• Joint Managing Conservatorship is the same default presumption
• Possession and access under the SPO or ESPO follows the same rules
• Child support obligations are calculated identically
• Decision-making rights for education, medical care, and other major issues can be shared or divided

The court doesn't penalize a parent for not being married. What matters is the history of involvement, the relationship with the child, and the best-interest analysis.

Common Situations for Unmarried Parents

The involved father with no court order. You've been co-parenting informally for years, but there's no legal custody arrangement. If the relationship deteriorates, there may be no court-ordered schedule to enforce. Filing a SAPCR proactively protects your relationship with your child.

The mother seeking child support. Filing a SAPCR establishes both support obligations and a formal possession schedule. Many mothers file through the Attorney General's office, which can simultaneously establish paternity, order support, and request a possession schedule.

Paternity disputes. If there's a question about biological parentage, the court orders DNA testing. If the test confirms paternity, the court establishes the parent-child relationship and proceeds with custody and support determinations.

The Texas Child Custody & Parenting Plan Guide covers custody for both married and unmarried parents, including the SAPCR filing process, how to document your parenting involvement for the best-interest analysis, and the specific steps for establishing conservatorship rights when there's no divorce case to attach to.
