Texas law, explained
The short answer
In Texas, paternity is established in one of three ways: both parents sign an Acknowledgment of Paternity, the law presumes the mother's husband is the father, or a court adjudicates paternity, usually after genetic testing. Legal paternity makes a man the child's legal father, but it does not by itself create a custody or visitation schedule. That takes a court order. John B. Polk, a Dallas family lawyer for more than 25 years, handles paternity, custody and support cases for fathers and mothers.
How paternity is established in Texas
Paternity is established by a signed Acknowledgment of Paternity, by a legal presumption, or by a court order. Each one makes a man the child's legal father, with the rights and duties that come with it.
Acknowledgment of Paternity
When parents are not married, both can sign an Acknowledgment of Paternity, often at the hospital when the child is born. Once it is filed with the state's vital statistics unit, it has the same effect as a court finding of paternity. A signer can rescind it within 60 days after it takes effect, or earlier if a court case about the child starts first (Texas Family Code § 160.307).
Presumed father
A man is presumed to be the father if he was married to the mother when the child was born, or if the child was born within 300 days after the marriage ended, among other grounds such as living with the child for the first two years and holding the child out as his own (Texas Family Code § 160.204). The presumption can be challenged, but strict time limits apply.
Court order after genetic testing
When parents disagree, either one can file a suit to adjudicate parentage. The court orders genetic testing. A result showing at least a 99 percent probability of paternity and a combined paternity index of at least 100 to 1 identifies the man as the father, unless other genetic testing rebuts it (Texas Family Code § 160.505).
What legal paternity gives a father, and what it does not
Legal paternity gives a father the same standing as any parent, but it does not give him a schedule. Until a court signs an order in a suit affecting the parent-child relationship, there is no enforceable visitation time, no decision-making order and no child support amount.
That gap is why many fathers who signed the acknowledgment at the hospital later find they cannot make anyone follow a schedule. Police generally cannot enforce time with a child that no court has ordered.
Once paternity is established, the court decides conservatorship (custody), possession and access (visitation) and child support under the same rules that apply in a divorce. Texas law presumes it is in a child's best interest for both parents to be named joint managing conservators, unless facts such as family violence change that (Texas Family Code § 153.131). Joint conservatorship covers rights and decisions. It does not automatically mean equal time.
More on how custody is decided is on the child custody page, and schedules are covered on visitation and relocation.
When paternity is disputed
When one parent will not cooperate, the court can order genetic testing and enforce that order by contempt. If the man whose paternity is being decided refuses court-ordered testing, the court can decide parentage against his position. If the mother refuses, the court can order testing of the child and the man without her (Texas Family Code § 160.622).
- If a mother refuses testing, the court can order testing of the child and the alleged father without her.
- If a man refuses to acknowledge the child, the mother or the Office of the Attorney General can file to have him adjudicated the father and ordered to pay support.
- If more than one man may be the father, the court orders testing, and if more than one man is identified, it orders further testing to find the genetic father.
Disputes over who is the father often arrive with disputes over money and time with the child. Settling the paternity question first, with testing, usually makes the rest easier to resolve.
How John B. Polk helps in a paternity case
Texas does not require a lawyer for a contested paternity case, but the deadlines in Chapter 160 are short, a missed one can make a DNA result irrelevant, and the final order on custody and support can last until the child is grown. That is when legal help matters most.
John has practiced family law in Dallas for more than 25 years and has worked extensively with the Office of the Attorney General's child support division and the Texas courts on paternity and support. He represents both fathers and mothers.
- Explains which route fits: acknowledgment, agreed order or contested suit.
- Requests genetic testing and reviews the results.
- Asks for a possession schedule, conservatorship and support in the same case, so the order is complete.
- Checks deadlines that can close a challenge, which are strict in paternity law.
- Prepares a contested case as if it will go to trial while exploring settlement.
When choosing a paternity lawyer for a father's case, look for someone who handles paternity and custody regularly in Dallas County, knows how the OAG process works, and will tell you plainly what the law allows. You can read about John on the about page.
Options: agreement, mediation or court
How long a paternity case takes in Texas depends on whether paternity is disputed, how quickly testing is done, and whether the parents agree on custody, visitation and support. No fixed waiting period applies to a paternity case the way the 60-day period applies to divorce.
When both parents accept the test result and agree on a schedule, the case can end with an agreed order. When they agree on paternity but not on the parenting plan, mediation is often the next step. John mediates in person at his Turtle Creek office or over Zoom. When agreement is not possible, the judge decides.

I highly recommend John for anyone going through a divorce. He was always available to give advice and strategize. I interviewed many firms big and small but chose John because of his experience and personal touch. He was very responsive. I felt like he was truly invested in making sure that I had the best outcome possible, and I believe that I did. Call John if you want a great lawyer who treats his clients like family.
Questions people ask
Can I get custody if my name isn't on the birth certificate?
Yes. A man who claims to be the father can file a paternity suit and ask for conservatorship and a possession schedule in the same case. Once paternity is established by testing or agreement, the court decides custody by the child's best interest, as it would for any parent. Being left off the birth certificate does not stop a father from asking.
How can an unmarried father get visitation rights?
An unmarried father gets enforceable visitation through a court order. First paternity must be legally established, by an Acknowledgment of Paternity or by a court finding. Then the court sets a possession schedule, which the parents can agree on or the judge can decide.
Can a mother request child support before paternity is established?
She can file for support, but a man is ordered to pay only once he is the legal father. In practice the mother, or the Office of the Attorney General, files one case that asks the court to establish paternity and set support together. Texas law also allows back child support for time before the case was filed, within the limits of Texas Family Code § 154.131.
Can I establish paternity if the father lives in another state?
Yes. Under the Uniform Interstate Family Support Act (Texas Family Code Chapter 159), a Texas court can decide paternity and support against a man in another state when he has certain ties to Texas, for example if the child was conceived here or he lived with the child here. Otherwise the case can be filed in his state, often with help from the OAG.
What if a child was born while the mother was married to someone else?
The mother's husband is presumed to be the father. A different man who believes he is the father generally must bring a case within four years after the child's birth, unless an exception in Texas Family Code § 160.607 applies. In some cases the husband can sign a denial of paternity while the biological father signs an acknowledgment.
Can grandparents request a paternity test for a grandchild?
Usually not on their own. Texas Family Code § 160.602 lets a relative of the mother within the second degree bring a parentage case only if the mother has died. Otherwise the case is brought by the child, the mother, the man, or a government agency such as the OAG.
Can a father request parental rights years after a child was born?
Often yes. If the child has no presumed, acknowledged or adjudicated father, a parentage case can be filed at any time while the child is a minor. If another man is the presumed father, the four-year limit and its exceptions in § 160.607 apply. The court still decides custody and time based on the child's best interest today.
Can a paternity case affect existing child support payments?
Yes. A paternity case can create a support order where none existed, or start the process of ending one for a man who is not the father. A man shown by testing not to be the father may, in limited cases, ask the court to end future support under Texas Family Code § 161.005, but support that came due before that order generally stays owed.
Can I challenge paternity after signing the birth certificate?
Yes, but the window is narrow. A signed Acknowledgment of Paternity can be rescinded within 60 days. After that it can be challenged only for fraud, duress or material mistake of fact, and only before a court order affecting the child, including a support order, has been issued (Texas Family Code § 160.308).
Do I need a lawyer for a contested paternity case?
The law does not require one, but a contested case has strict deadlines, testing rules and a custody and support order that can last until the child is grown. A lawyer makes sure the petition asks for everything you need and that no deadline passes. Talk to one before signing any acknowledgment, denial or agreed order.
Can a court order a DNA test to establish paternity?
Yes. In a Texas case to adjudicate parentage, the court must order genetic testing of the child and the other people involved when a party asks for it (Texas Family Code § 160.502). Testing cannot be ordered while the child is still in the womb, and where more than one man may be the father, the court can test them at the same time or one after another. In narrow situations, such as a late challenge to a presumed father who has raised the child as his own, the court can deny testing (§ 160.608). The Office of the Attorney General can also arrange genetic testing in its child support cases.
How do I correct the wrong father's name on a birth certificate?
In most cases you need a court order that establishes who the father is, or that states the man listed is not the father, and then an application to Texas DSHS Vital Statistics. Vital Statistics changes the father on an original birth record through its Application for New Birth Certificate Based on Parentage, supported by a certified copy of the court order or another accepted document, such as an Acknowledgment of Paternity. Where the man listed is the mother's husband and everyone agrees, the biological father's Acknowledgment of Paternity together with the husband's Denial of Paternity can sometimes replace a court case (Texas Family Code § 160.303). Strict deadlines apply to challenging an acknowledgment or a presumed father, so talk to a family lawyer before you file anything.
