A father whose name appears on a birth certificate often assumes that settles it. In Texas it frequently does not. Being listed on the certificate is a record of who reported the birth, not an independent legal determination of parentage, and a father who has never established paternity has no enforceable right to possession, no right to make decisions, and no standing to object if the mother moves out of state.
Establishing paternity in Texas is governed by Chapter 160 of the Family Code, the Uniform Parentage Act, and it operates through mechanisms with deadlines that close permanently. Our family law attorneys in Conroe handle paternity matters for both fathers and mothers. Here is how it works.
The Presumption of Paternity
Texas Family Code Section 160.204 establishes when a man is presumed to be a child’s father. The presumption applies when he is married to the mother and the child is born during the marriage, when the child is born within 300 days after the marriage terminates, and in certain circumstances involving marriages entered after birth or continuous residence with the child during the first two years combined with a representation of paternity.
A presumed father has parental rights and obligations without further action. This is why married fathers rarely encounter the issues discussed here, and why unmarried fathers encounter all of them.
The presumption also has a consequence people find counterintuitive. If a married woman has a child with someone other than her husband, the husband is the presumed father as a matter of law, and the biological father has no rights until the presumption is rebutted through a court proceeding.
The Acknowledgment of Paternity
For unmarried parents who agree, the Acknowledgment of Paternity is the simplest path. It is a form signed by both the mother and the biological father, typically at the hospital after birth or later through the Office of the Attorney General or a local registrar.
Once filed with the Texas Vital Statistics Unit, a valid AOP has the effect of an adjudication of paternity. It establishes the legal parent-child relationship, permits the father’s name on the birth certificate, and creates support obligations and inheritance rights.
An AOP cannot be used where the child has a presumed father unless that presumed father signs a Denial of Paternity. Both documents must be filed together.
The rescission and challenge deadlines
These are the provisions that catch people, and they are unforgiving.
A signatory may rescind the AOP by filing a completed rescission form before the earlier of the 60th day after the effective date, or the date of the first court hearing in a proceeding to which the signatory is a party relating to the child.
After that period, a challenge is limited. A signatory may bring a proceeding to challenge the acknowledgment only on the basis of fraud, duress, or material mistake of fact, and generally must do so within four years of filing.
Note what is absent from that list. Discovering later that you are not the biological father is not automatically a basis for relief. Texas courts have upheld acknowledgments against men who signed knowing they might not be the biological father, on the theory that the acknowledgment was a knowing assumption of parentage rather than a mistake. Signing an AOP without genetic testing when there is any genuine question is a decision with permanent consequences.
Adjudicating Parentage Through the Courts
When parents do not agree, or when a presumed father must be displaced, parentage is determined through a suit to adjudicate parentage under Subchapter G of Chapter 160.
The suit may be brought by the mother, the man claiming to be the father, the child through a representative, the Office of the Attorney General in a support case, or others with standing under the statute.
Genetic testing is the core evidence. Section 160.505 provides that a man is rebuttably identified as the father if testing shows at least a 99 percent probability of paternity and a paternity index of at least 100 to 1. Courts routinely order testing on motion, and refusal to submit can result in an adjudication against the refusing party.
The four-year limitation on challenging a presumed father
Section 160.607 generally bars a proceeding to adjudicate the parentage of a child with a presumed father after the child turns four. Exceptions exist, including where the court determines the presumed father and the mother did not live together or engage in sexual intercourse during the probable time of conception, or where the presumed father was precluded from asserting paternity by misrepresentation.
The practical effect is that a biological father who waits past a child’s fourth birthday to assert paternity against a presumed father may find the door closed entirely.
What Establishing Paternity Actually Gives You
For the father, establishing paternity is the prerequisite to everything else. Until it exists, there is no basis for a court to order possession and access, no right to participate in medical or educational decisions, and no standing to contest a relocation or an adoption.
Paternity alone does not create a possession schedule. It establishes the relationship. A separate order addressing conservatorship, possession, and support is what actually structures the parenting arrangement, and it is typically sought in the same proceeding. Our pages on child custody and child support address what that order contains.
For the child, paternity establishes inheritance rights, eligibility for benefits including Social Security and veterans benefits, access to family medical history, and the right to support.
For the mother, it establishes an enforceable support obligation and creates a second legally responsible parent.
Common Situations
The father was never told about the child. Texas maintains a paternity registry, and a man who wishes to preserve the right to notice of an adoption proceeding may register. Failing to register or otherwise assert paternity timely can result in termination of parental rights without personal notice.
The mother refuses testing. File a suit to adjudicate parentage and move for court-ordered genetic testing. This is not a situation requiring cooperation.
The father is paying support informally. Informal payments generally do not count as credit against a later support order, and they do not establish paternity. Document everything and formalize the arrangement.
A man discovers he is not the biological father years later. Texas provides a limited procedure to terminate the parent-child relationship of a man who is not the biological father, subject to strict requirements and deadlines and to the court’s assessment of the child’s best interest. It is narrow relief, and the mistaken-paternity statute does not eliminate arrearages already accrued.
Montgomery County Practice
Paternity suits in Montgomery County are heard in the district courts. The Office of the Attorney General Child Support Division also brings paternity and support proceedings, and those cases proceed on a separate track with their own dockets.
An important distinction: the OAG represents the State’s interest in establishing support, not either parent. A father who appears at an OAG proceeding expecting an advocate on possession issues will not find one there. Possession and access are generally not addressed in OAG support proceedings, and obtaining a possession order usually requires a separate private action.
Genetic testing is readily available through court-approved facilities in the Conroe and Houston area, and results typically return within a few weeks.
Frequently Asked Questions
Does signing the birth certificate establish paternity in Texas?
Not by itself. The legal effect comes from a validly executed and filed Acknowledgment of Paternity, a court adjudication, or the marital presumption, not from the certificate alone.
How long do I have to rescind an Acknowledgment of Paternity?
Before the earlier of the 60th day after the effective date, or the date of the first hearing in a proceeding relating to the child to which you are a party. After that, challenges are limited to fraud, duress, or material mistake of fact, generally within four years.
Can I get custody just by establishing paternity?
No. Paternity establishes the legal relationship. A separate order is required to establish conservatorship, possession, and access, and it is usually requested in the same suit.
What if the mother is married to someone else?
Her husband is the presumed father. The biological father must bring a suit to adjudicate parentage, generally before the child turns four, subject to statutory exceptions.
Can paternity be established after the child is an adult?
A proceeding to adjudicate parentage of a child with no presumed or acknowledged father may generally be brought at any time, including after the child reaches adulthood.
Will I owe back child support?
A court may order retroactive support, typically limited to four years before the filing absent specific findings, considering the obligor’s ability to pay and prior voluntary support provided.
