Establishing Paternity Laws in Texas
Establishing paternity in Texas means making a man’s legal fatherhood official. A husband married to the mother when the child is born is usually already presumed to be the father, without any extra paperwork. For every other man, that recognition takes signing an Acknowledgment of Paternity, or asking a court to adjudicate parentage.
Until one of those steps happens, or unless a presumption already applies, there is no final court order for custody, visitation, or child support tied to the relationship.
Texas law recognizes the father-child relationship in a specific, limited number of ways, and picking the wrong path costs real time. A signed acknowledgment can take effect the same day a child is born, while a contested court case can take months. Knowing which path fits your situation, and what each one actually requires, is the first decision that shapes everything after it.
The Two Paths to Establishing Legal Paternity in Texas
Texas law establishes the father-child relationship several ways, including an unrebutted presumption, a voluntary acknowledgment, a court adjudication, or adoption.[1] For parents who are not already covered by a presumption of paternity, establishing that relationship comes down to two real options: signing an Acknowledgment of Paternity, or filing a Suit to Adjudicate Parentage.
Before either path applies, it helps to know where you stand if the mother is or was married to someone else. Our overview of paternity rights in Texas covers the presumption of paternity that can automatically apply to husbands, and how that presumption interacts with the two paths described here. This page focuses on what it actually takes to complete either path once you know which one fits your situation.
Establishing Paternity by Signing an Acknowledgment of Paternity
An unmarried mother and a man claiming to be the biological father can sign an Acknowledgment of Paternity, commonly called an AOP, without going to court at all. To be valid, the AOP must be in a record, signed or otherwise authenticated by both parents under penalty of perjury, and state whether genetic testing has occurred.[2]
The AOP takes effect on the date of the child’s birth or the date it is filed with the Vital Statistics Unit, whichever comes later. There is no filing fee. Once filed, it carries the same legal weight as a court order establishing paternity.
An AOP is void if it names a different presumed father without his signed denial, or if it falsely claims the child has no other father on record. Either signatory can rescind it before the 60th day after the acknowledgment takes effect, or before any court proceeding involving the child begins, whichever is earlier.[3] After that window closes, undoing it requires proving fraud, duress, or a material mistake of fact in a separate court proceeding.
Establishing Paternity Through a Court-Ordered Adjudication
When parents disagree, when the mother is married to someone else, or when an AOP is not an option, establishing paternity requires filing a Suit to Adjudicate Parentage. Texas law gives standing to file this suit to a specific list of people, not just the parents themselves.[4]
A Suit to Adjudicate Parentage may be filed by:
- The child, directly.
- The mother of the child.
- A man whose paternity of the child is to be adjudicated.
- A support enforcement agency or another government agency authorized by law.
- An authorized adoption agency or licensed child-placing agency.
- A representative authorized by law to act for someone deceased, incapacitated, or a minor, who would otherwise have had standing to bring the case themselves.
- A close relative of a deceased mother, within the second degree of consanguinity.
- An intended parent, in cases involving assisted reproduction or a gestational agreement.
The mother and the man whose paternity is at issue must both be made parties to the case. Venue belongs in the county where the child lives, the county where the respondent lives if the child is out of state, or the county handling probate of the presumed or alleged father’s estate.[5]
How Courts Actually Decide Paternity at Trial
Once a Suit to Adjudicate Parentage is filed, Texas law gives courts three ways to resolve the question. A respondent can simply admit paternity under oath or by filing a pleading, and the court can adjudicate him as the father on that basis alone.
If paternity is contested, the court can order genetic testing through an accredited laboratory. A man is rebuttably identified as the father if testing shows at least a 99 percent probability of paternity and a combined paternity index of 100 to 1 or higher.[6] Once testing clears that bar, the court must adjudicate him as the father unless he produces conflicting genetic testing of his own.
If a party who was properly served does not respond, and the court separately finds him to be the father, the court can adjudicate paternity by default. In a court proceeding to adjudicate parentage, the judge, not a jury, decides paternity; Texas law specifically prohibits a jury in these cases.
What Happens Once Paternity Is Established
Signing a valid AOP or receiving a court order adjudicating paternity does not, by itself, create a parenting schedule or a support order. That comes next, through a separate Suit Affecting the Parent-Child Relationship addressing conservatorship, possession and access, and child support.
Establishing paternity is what makes that second step possible in the first place. Many parents file the paternity suit and the parent-child relationship suit together, so the parenting structure is in place as soon as fatherhood is confirmed rather than months later.

Getting paternity established correctly the first time matters more than most people realize, since undoing a signed acknowledgment or a default judgment later is far harder than doing it right at the outset. We think many moves ahead, identifying which path actually fits your situation before you sign anything or file anything, and building the case for genetic testing or standing when the situation is contested.
The Ramage Law Group represents mothers, fathers, and other parties establishing paternity across Collin County, Denton County, and Dallas County, in different cases depending on which side of the question they are on.

Frequently Asked Questions
What are the two ways to establish paternity in Texas?
If a presumption of paternity doesn’t already apply, such as when the parents aren’t married, there are two ways to establish it. An unmarried mother and father can sign an Acknowledgment of Paternity without going to court, or file a Suit to Adjudicate Parentage and let a court decide.
Who can file a Suit to Adjudicate Parentage in Texas?
Texas law gives standing to the child, the mother, and the man whose paternity is at issue. It also extends to a support enforcement agency, an adoption agency, a representative for someone deceased, incapacitated, or a minor, a close relative of a deceased mother, and an intended parent in assisted reproduction cases.
How much genetic testing proof does a court need to establish paternity?
Texas law sets a specific threshold: at least a 99 percent probability of paternity and a combined paternity index of 100 to 1 or higher. Once testing clears that bar, the court must adjudicate the man as the father unless he produces conflicting test results.
Can paternity be established without a trial?
Yes. Signing a valid Acknowledgment of Paternity avoids court entirely, and even inside a filed case, a respondent can admit paternity under oath or by pleading and have the court adjudicate him as the father on that basis.
Is there a jury in a Texas paternity case?
No. Texas law specifically prohibits a jury in a proceeding to adjudicate paternity. The judge decides the question instead.
