Texas Establishing Paternity Laws

Establishing paternity in Texas is the legal process of naming a child’s father so his rights and duties take effect. You can do it two main ways: both parents sign an acknowledgment, or a court decides it, sometimes with genetic testing. [1]

Paternity is the legal foundation under child support, custody, and visitation. Until it is established, an unmarried father has no legal right to his child, and the child has no legal right to his support. Settling it early protects everyone involved.

“From the very first time I walked into his office, Michael showed compassion and understanding for the unique circumstances of my case, which involved my child and a serious medical condition. He immediately recognized how important my child’s safety and wellbeing were to me.

What stood out the most was that he truly listened. He treated our situation with respect, urgency, and care. Michael is also incredibly knowledgeable, and his experience and confidence were evident throughout the entire process. Because of this, I always felt supported and reassured that we were in the best hands.

I’m incredibly grateful for his help and would highly recommend him to anyone looking for an attorney who truly cares about the families he represents.

If I ever need legal help again, he will be the first person I would call.”

    When Texas Already Presumes a Father

    • Texas law presumes a man is the legal father in certain situations, without any extra step. The presumption applies mainly to married couples. [2]
      • The man was married to the mother when the child was born.
      • The child was born within 300 days after the marriage ended.
      • The man married the mother after birth and voluntarily claimed the child.

      When no presumption applies, usually because the parents were unmarried, paternity must be established. That is where the two paths below come in.

      Path One: Acknowledgment of Paternity

      The simplest route is a voluntary Acknowledgment of Paternity, often called an AOP. Both parents sign a sworn form naming the father, and it is filed with the Texas Vital Statistics Unit. [3]

      Parents can sign the AOP at the hospital when the child is born or any time afterward. Once filed, a valid AOP carries the same legal force as a court order of paternity.

      Either parent can cancel an AOP within a short window, up to 60 days after signing, or before a first court case about the child. [4] After that window, an AOP can be challenged only for fraud, duress, or a material mistake of fact.

      Path Two: A Court Order of Paternity

      When the parents disagree, or when someone contests fatherhood, a court decides paternity. This is called a suit to adjudicate parentage, and either parent or the Attorney General can start it.

      The court can order genetic testing of the mother, child, and alleged father. A cheek swab is compared at an accredited lab, and a match usually shows a probability above 99 percent. [5]

      If the testing identifies the father, the court signs an order adjudicating paternity. That order sets the legal father and opens the door to support, custody, and visitation.

      How the Court Process Works Step by Step

      A contested paternity case follows a clear path. The process is manageable when you know each step.

      1. File a petition to adjudicate parentage. A parent or the Attorney General opens the case in the county with proper jurisdiction.
      2. Serve the other party. The other parent or alleged father receives notice and a chance to respond.
      3. Complete genetic testing. The court orders DNA testing when fatherhood is in question, and declining it carries consequences.
      4. Attend the hearing. The judge reviews the results and any evidence, then decides parentage. Paternity cases are decided by a judge, not a jury.
      5. Get the order and next steps. The order can also set child support, custody, and a visitation schedule.

      What Establishing Paternity Unlocks

      Establishing paternity is not just a label. It turns on the parental rights in Texas that protect both the child and the father.

      • The child’s right to child support from both parents.
      • The father’s standing to seek child custody and visitation.
      • The child’s right to inherit from the father.
      • Access to the father’s medical history and family health record.
      • Eligibility for benefits such as Social Security, veterans, and health insurance.

      Deadlines You Should Know

      Timing can decide whether a case is even allowed to proceed. [6]

      • If a child already has a presumed father, a suit to change that usually must be filed within four years of the child’s birth.
      • If a child has no presumed, acknowledged, or adjudicated father, a case can generally be filed at any time.

      These deadlines have exceptions, and they turn on specific facts. If you are close to a limit, it is worth confirming your position quickly.

    Frequently Asked Questions

    Do unmarried parents automatically have a legal father?

    No. When parents are unmarried, there is usually no presumed father. Paternity has to be established by an acknowledgment or a court order.

    Is a father’s name on the birth certificate enough?

    Not by itself. The legal step is a signed and filed Acknowledgment of Paternity or a court order. The birth certificate alone does not establish full legal rights.

    Can I still get a paternity order if the Attorney General is involved?

    Yes. Many Texas paternity and support cases run through the Attorney General. You still have the right to your own attorney in that process.

    What happens if someone refuses genetic testing?

    Refusing a court-ordered test carries consequences. A judge can treat the refusal against that party or decide paternity by default.
