Paternity disputes in the context of a Texas divorce are among the most legally and emotionally complex situations a family law case can present. When significant wealth is involved, the stakes rise even further. Questions about who is a child’s legal father affect not only the emotional lives of everyone involved, but also child support obligations, inheritance rights, health insurance coverage, and the overall financial settlement of a high-net-worth divorce.
This guide explains how Texas law handles contested paternity in a divorce context, when and how paternity can be challenged, what DNA testing means legally, and what high-asset families in the Houston area need to understand before proceeding.
Understanding Presumed Paternity in Texas
Texas law automatically establishes a presumption of paternity in certain circumstances. Under the Texas Family Code, a man is presumed to be the legal father of a child if he was married to the mother when the child was born, if the child was born within 300 days of the end of the marriage, if the man married the mother during her pregnancy and acknowledged paternity, or if the man lived with the child continuously during the first two years of the child’s life and represented himself as the father.
The presumption of paternity has legal force. It means that child support can be ordered, custody rights attach, and the child may inherit from the presumed father without DNA testing ever occurring. Overcoming the presumption requires a legal proceeding and, typically, genetic testing.
For high-earning individuals in the Houston area, the financial implications of a mistaken paternity presumption are significant. Child support in Texas is calculated as a percentage of net resources, and for high earners, the monthly obligation can reach substantial amounts. Additionally, if the divorce settlement is structured with the assumption that a certain number of children will need support, and paternity is later disputed for one of those children, the entire financial arrangement may need to be revisited.
When Paternity Is Contested: The Legal Standards
A presumed father who disputes that he is the biological parent of a child born during the marriage must take legal action to challenge the presumption. Texas law allows a presumed father to contest paternity on certain grounds, including fraud or misrepresentation by the mother about the identity of the child’s biological father, a mistake of fact where both parties genuinely but incorrectly believed the man was the biological parent, or the existence of another man who may be the biological father.
Timing matters. Texas law generally requires that a challenge to a presumption of paternity be brought within four years of the child’s birth. However, if the challenge is based on fraud or misrepresentation, and the presumed father did not discover the relevant facts until later, the four-year window may run from the date of that discovery rather than the date of birth. If the presumed father signed an Acknowledgment of Paternity without first obtaining genetic testing, Texas Senate Bill 785 provides a separate pathway to challenge the parent-child relationship within one year of discovering the relevant facts.
Courts in divorce proceedings have the authority to order genetic testing when paternity is genuinely in dispute. Under Texas law, if ordered by the court, neither the alleged father, the mother, nor the child can refuse DNA testing without facing legal consequences including contempt of court. Modern genetic testing identifies whether a man is the biological father with essentially certainty: a match produces a result of 99.999% probability, and a non-match conclusively rules out biological paternity.
What Happens If DNA Testing Shows Non-Paternity?
A DNA result showing that the presumed father is not the biological parent does not automatically terminate the legal parent-child relationship. The presumed father must file a petition asking the court to terminate the relationship, and the court must hold a hearing to determine if the legal requirements are met before ordering genetic testing or acting on results already obtained.
If the court ultimately terminates the parent-child relationship, the man is released from the obligation to pay future child support from the date the court order is signed. However, he remains responsible for any unpaid child support that accrued before the order was entered. This means that a man who has been paying support under a court order while waiting for the paternity dispute to be resolved may not be able to recover those payments even if DNA later confirms he is not the father.
The Texas Attorney General’s Office also has procedures for addressing mistaken paternity in child support cases. The office requires testing by a lab accredited by the AABB (formerly the American Association of Blood Banks) and will seek termination of the support obligation if testing confirms the man is not the biological father. However, the obligation for past-due support remains.
The Child’s Best Interests: A Complicating Factor
Texas courts balance the legal framework of paternity with a fundamental principle in all family law matters: the best interests of the child. In some contested paternity cases, a court may determine that maintaining the legal parent-child relationship, even in the absence of biological connection, serves the child better than terminating it.
This is particularly true when the presumed father has been the child’s only father figure, when the child has formed a deep attachment to the presumed father, or when the biological father is unknown or unwilling to assume parental responsibility. Courts consider the emotional and practical impact on the child of disrupting an established parent-child relationship.
In high-stakes divorces where other significant financial issues are also being resolved, paternity disputes can sometimes be resolved through negotiated agreements that address both the legal parent-child question and the financial arrangements that flow from it. Whether this approach is appropriate depends entirely on the specific facts and the interests of the child, the parents, and any other children in the family.
High-Net-Worth Considerations in Contested Paternity Cases
For high-earning spouses in the Houston area, a contested paternity issue during a divorce intersects with property division, support calculations, and inheritance planning in ways that require careful coordination between family law and estate planning counsel.
Child support in Texas is capped at a net monthly resource threshold, but the court can award additional support above the standard guidelines for children’s extraordinary expenses, including private school tuition, medical needs, and extracurricular activities. In a high-stakes divorce involving a contested child, these additional support amounts can be substantial and are worth analyzing carefully.
Inheritance rights also turn on legal parenthood. A child who is legally the son or daughter of a high-net-worth individual has statutory inheritance rights under Texas law if that individual dies without a will, and potentially under a will or trust even with one. When paternity is contested, the question of who inherits and under what circumstances requires attention from both divorce counsel and the estate planning attorney.
Confidentiality is a concern in high-profile or high-net-worth cases. While family court proceedings in Texas are generally not public in the same way that civil court records are, the parties’ identities and the basic facts of any litigation can sometimes become known. Expedient and private resolution, whether through DNA testing that resolves the dispute quickly or through negotiated terms that address all issues simultaneously, is often in everyone’s interest.
Practical Steps for Houston Area Clients
If you are a presumed father who has doubts about the biological parentage of a child and you are going through a divorce, do not wait. The timing requirements for challenging paternity under Texas law are strict, and delays can result in the loss of your right to contest. Consulting with a family law attorney at the outset of the divorce is essential.
If you are a mother and the biological father of your child may not be your husband, disclosure to your attorney is critical. Attempting to conceal a paternity question during a divorce can result in serious legal consequences, including being held in contempt of court and adverse findings in the property and custody portions of the case.
If you are seeking to establish paternity, working through the proper legal channels rather than relying on informal DNA testing or private agreements will protect both you and the child.
