“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.”
Texas Paternity Laws
Without established paternity, a father has no legal right to custody or visitation, and a child has no legal right to support him. Establishing paternity is straightforward in some cases and contested in others. The route that fits depends on whether the parents were married, whether a presumption applies, and whether anyone is challenging who the father is.

How Texas Establishes Paternity
Texas recognizes three main routes to legal paternity. Knowing which one applies to your case shapes everything that comes next.[1]
Presumption. A man is automatically presumed to be the father in several situations defined by statute, most commonly when the parents were married at the time of birth.[2] A presumption can be confirmed by an order or rebutted under specific circumstances.
Acknowledgment of Paternity. Both parents can sign a sworn Acknowledgment of Paternity form that is filed with the Texas Vital Statistics Unit. A properly executed acknowledgment has the same effect as a court order adjudicating parentage.[3]
Court adjudication. When the parents do not agree, when a presumption is being challenged, or when an acknowledgment cannot be used, the court adjudicates parentage. Genetic testing is typically part of this process.[4]
The Presumption of Paternity
Texas law presumes a man is the father in any of these situations:
- Marriage at birth. He was married to the mother and the child was born during the marriage.
- Marriage ending recently. He was married to the mother and the child was born within 300 days of the marriage ending by death, divorce, or annulment.
- Marriage after birth. He married the mother after the child’s birth and voluntarily asserted paternity in writing with the Vital Statistics Unit, was named on the birth certificate with his consent, or promised in writing to support the child.
- Holding out. During the first two years of the child’s life, he continuously lived in the household with the child and represented to others that the child was his.
A presumption is not a guarantee. It can be confirmed, or it can be rebutted. Rebuttal can come from an Acknowledgement of Paternity by another man, a denial of paternity filed with an acknowledgment, or a court adjudication that names another man as the father.
Acknowledgment of Paternity (AOP)
The Acknowledgment of Paternity is the most common voluntary route for unmarried parents. Both parents sign a sworn AOP form, which is then filed with the Texas Vital Statistics Unit. The acknowledgment can be signed at the hospital after birth or any time afterward.
Once filed, a valid AOP has the same legal effect as a court order. It establishes the father’s rights and duties under Texas law.
An AOP can be rescinded by either parent during a short window: within 60 days of signing, or before the date of the first court proceeding to which the signatory is a party, whichever is earlier.[5] After that window closes, the acknowledgment can only be challenged on limited grounds.
A challenge after the rescission window requires proof of fraud, duress, or material mistake of fact. The challenge has to be brought within four years of the acknowledgment being filed. Genetic testing alone is not enough to set aside an AOP after the window closes.
Court Adjudication of Paternity
When the voluntary route is not available or not appropriate, a court adjudicates parentage. This happens when the parents disagree about who the father is. It also happens when a presumed father wants to challenge the presumption, or when a man is refusing to sign an AOP.
Genetic testing is typically part of an adjudication case. A test result showing at least a 99 percent probability of paternity and a combined paternity index of at least 100 creates a rebuttable presumption of paternity.[6]The test result can be rebutted only with another genetic test of equal or higher reliability that excludes paternity.
The court issues an order adjudicating the parent-child relationship. That order is the foundation for everything that follows: custody, possession, child support, medical support, and inheritance rights. In many cases, the adjudication and a Suit Affecting the Parent-Child Relationship are decided together so a single order covers parentage and parental rights.
What Paternity Establishes
Establishing paternity opens specific rights and duties that simply do not exist before parentage is legally recognized.
For the child: the right to receive child support and the right to inherit from both parents. Establishing paternity also brings eligibility for Social Security and military benefits through the father, access to the father’s medical history, and the legal recognition of having two parents.
For the father: standing to seek conservatorship and possession of the child. He also gains the right to be notified of legal decisions about the child, and the right to a legally protected relationship with the child.
For the mother: the legal mechanism to seek child support and medical support from the biological father, and a co-parent who is legally accountable for the child’s care.
Custody and visitation rights flow only from established parentage. A father who has not had paternity legally established has no standing in court to seek time with the child, no matter how involved he has been informally.
Time Limits for Paternity Cases in Texas
Texas paternity law treats time limits differently depending on who is involved and what is being requested.
- No presumed or acknowledged father: a case to establish paternity can be filed at any time, because no statute of limitations applies.
- Presumed father: a challenge to the presumption must generally be filed within four years of the child’s birth, with limited exceptions.
- Acknowledgement of Paternity: a rescission must be filed within 60 days of signing or before the first court proceeding, whichever is earlier; a later challenge requires fraud, duress, or material mistake of fact within four years.
These deadlines are strict. Missing them can permanently close off the ability to establish or challenge paternity, so getting in front of a case early matters.[7]
Disestablishing Paternity
Paternity disestablishment is the process of removing legal paternity that has already been established. It is more difficult than establishing paternity in the first place, and Texas law sets tight limits on when and how it can happen.
A man challenging a paternity finding has to act inside the statutory time limit and prove a specific legal ground. Common grounds include fraud, duress, or material mistake of fact at the time the AOP was signed, or evidence rebutting a presumption that did not apply to begin with.
Disestablishment cases are factually intense and procedurally demanding. They also affect the child directly, because removing a father from a child’s legal life is not something a court does casually. Working with experienced counsel from the start protects both the case and the relationships involved.
Frequently Asked Questions
There are three main routes. If the parents were married at the time of birth, paternity is presumed. If they were not, both parents can sign an Acknowledgement of Paternity that is filed with the Vital Statistics Unit. When the parents do not agree, a court adjudicates parentage, typically with genetic testing.
A properly signed and filed AOP has the same legal effect as a court order. It establishes the man as the legal father with all the rights and duties that come with parentage, including child support, custody standing, and inheritance rights for the child.
Yes, but only inside narrow time limits. Either parent can rescind the AOP within 60 days of signing or before the first court proceeding, whichever is earlier. After that, the AOP can be challenged only for fraud, duress, or material mistake of fact, and the challenge must be filed within four years.
It depends. When there is no presumed or acknowledged father, a paternity case can be filed at any time. When there is a presumed father, a challenge usually must be filed within four years of the child’s birth, with limited exceptions.
Not in every case. When parents sign an Acknowledgment of Paternity voluntarily, DNA testing is not required. In a contested adjudication, the court typically orders genetic testing. A result showing at least 99 percent probability and a combined paternity index of at least 100 creates a rebuttable presumption of paternity.
No. Establishing paternity gives the father standing to seek custody and visitation, but it does not by itself create a possession schedule. A Suit Affecting the Parent-Child Relationship is typically filed alongside or after the paternity case to set conservatorship, possession, and support.
Yes. Texas law allows posthumous paternity proceedings, often pursued for inheritance, Social Security, or other benefits. These cases have their own procedural requirements and frequently rely on genetic testing of relatives or preserved samples.
