If you are paying child support in Texas for a child that is not yours, the law gives you a route out through Section 161.005 of the Texas Family Code, the “mistaken paternity” statute. You file a petition to terminate the parent-child relationship, the court orders DNA testing, and if the test excludes you as the biological father, the judge must terminate the relationship and end your future support obligation. The catch is a strict two-year deadline that starts the moment you learn facts suggesting the child may not be yours.1State of Texas. Texas Code FAM 161.005 – Termination When Parent Is Petitioner
If You Signed an AOP in the Last 60 Days, Rescind Instead
Before going through the full termination process, check the calendar. If you signed an Acknowledgment of Paternity (AOP) within the past 60 days and no court proceeding involving the child has been filed, either signatory can rescind the AOP directly.2State of Texas. Texas Code FAM 160.307 – Procedures for Rescission You do not have to prove anything about biology. File a rescission form with the Vital Statistics Unit, send a certified-mail copy to the other signatory, and the unit voids the acknowledgment and amends the birth record.
This window closes fast. Once 60 days pass, or once any court case involving the child begins (including a child support case filed by the mother or the Attorney General), rescission is off the table and you are into the harder mistaken paternity process.2State of Texas.

Who Can Use the Mistaken Paternity Statute
Section 161.005 is available to a man who either signed an AOP or was declared the father by a court order in a proceeding where no genetic testing was done. That second piece matters. If DNA testing was already conducted during the original paternity case and confirmed you as the father, this statute does not help you.1State of Texas. Texas Code FAM 161.005 – Termination When Parent Is Petitioner
Your petition must allege that you believed you were the biological father at the time and that misrepresentations led you to that belief. Simply not knowing is not enough. You need something you can point to that caused your mistaken belief.
Three groups are barred from using the statute entirely:
- Adoptive fathers who legally adopted the child.
- Men who consented to assisted reproduction that resulted in the child.
- Intended fathers under a court-validated gestational agreement.
In each case, the man knowingly took on the parental role without any expectation of a biological connection, so the statute closes the door.1State of Texas. Texas Code FAM 161.005 – Termination When Parent Is Petitioner
The Two-Year Deadline Starts Sooner Than You Think
You have two years to file, and the clock does not start on the date of a DNA test. It starts on the date you learn facts suggesting you might not be the biological father.1State of Texas. Texas Code FAM 161.005 – Termination When Parent Is Petitioner A text message, a confession from the mother, or a blood type that does not match yours can all trigger it. Miss the deadline and a court will almost certainly refuse to hear the case, however strong your DNA evidence turns out to be.
Presumed Fathers Have a Different Clock
If your status as father rests on the marital presumption rather than an AOP or court order, a separate rule applies. A presumed father generally has to bring a proceeding to contest paternity within four years of the child’s birth. There is no time limit at all in two situations: if the presumed father and the mother did not live together or have sexual intercourse during the probable time of conception, or if the presumed father was prevented from filing sooner by a mistaken belief caused by misrepresentations about the child’s parentage.3State of Texas.

How the Court Process Works
You do not walk into court with a DNA test you bought on your own. The statute puts the court in charge of the testing, and there are several steps before results carry any weight.
Filing the Petition
The case begins with a verified Petition to Terminate the Parent-Child Relationship, filed in the same court and under the same cause number as the original child support order. The petition must lay out specific facts showing you believed you were the biological father and that misrepresentations produced that belief.1State of Texas. Texas Code FAM 161.005 – Termination When Parent Is Petitioner If you signed an AOP, request a certified copy from the Texas Department of State Health Services Vital Statistics Unit to include with your filing.4Texas Department of State Health Services. Application for Acknowledgment of Paternity AOP Inquiry
After filing, you must formally serve the child’s other parent. If the Office of the Attorney General was involved in the original child support case as the Title IV-D agency, it must also be served.5Office of the Attorney General. Mistaken Paternity
Pretrial Hearing and Court-Ordered DNA
Before any testing happens, the court holds a pretrial hearing to decide whether you have made a credible preliminary case. You are not proving anything beyond a doubt at this stage. You are giving the judge enough to justify ordering a DNA test. If the judge finds the threshold met, the court orders both you and the child to submit to genetic testing through an AABB-accredited laboratory.1State of Texas. Texas Code FAM 161.005 – Termination When Parent Is Petitioner Results from non-accredited labs will not be accepted, and chain-of-custody documentation has to verify how the samples were collected and handled.
The Ruling
The DNA result controls the outcome. If the test excludes you as the biological father, the court is required to terminate the parent-child relationship. The judge does not weigh the child’s best interest, does not consider how long you have been in the child’s life, and does not have discretion to deny the petition. Exclusion means termination. If the results identify you as the genetic father, the court must deny your petition and the parent-child relationship stays intact.1State of Texas.

What Termination Does to Your Support Obligation
A termination order under Section 161.005 has immediate financial effects, but it does not erase everything.
Future child support ends on the date the judge signs the order. Interest also stops accruing on any existing child support debt as of that date.1State of Texas. Texas Code FAM 161.005 – Termination When Parent Is Petitioner So if you owe $10,000 in back support on the day of termination, no additional interest piles on top of that balance going forward.
The $10,000 itself does not disappear. Any child support you failed to pay before termination remains a legally enforceable debt. The state can collect it through wage withholding, tax refund interception, and property liens. One limit does apply: the arrears cannot be enforced through contempt of court, so jail is off the table for pre-termination debt once the order is signed.1State of Texas. Texas Code FAM 161.005 – Termination When Parent Is Petitioner
You Cannot Get Back What You Already Paid
The question most men want answered is whether they can recover money they already paid. Texas law does not provide a mechanism to recover child support payments made before termination. The statute addresses future obligations and existing arrears; it says nothing about reimbursing amounts already collected and distributed to the custodial parent.
Keep Paying Until the Judge Signs the Order
Even if you are certain a DNA test will exclude you, do not stop paying on your own. Until a judge signs the termination order, the existing support order stays in full effect, and every missed payment becomes enforceable arrears.
Texas enforcement is aggressive. The Attorney General’s office can suspend your driver’s license, professional licenses, and hunting or fishing licenses. Liens can be placed on your property, bank accounts, and retirement plans. Your passport can be denied or revoked. Unpaid support can also be enforced through contempt of court, which carries the possibility of jail time.6Office of the Attorney General. How We Enforce The consequences of skipping payments while your case is pending are often worse than the support itself. File the petition, keep paying, and let the process run.
Costs to Plan For
A mistaken paternity case involves several out-of-pocket expenses. Filing fees for a family law petition in Texas typically run a few hundred dollars, with the exact amount varying by county. A court-admissible genetic test from an AABB-accredited lab generally costs between $350 and $500. A process server to deliver the petition usually runs roughly $75 to $200 depending on location and circumstances. Attorney fees are the largest variable, since a case that settles after DNA results costs far less than a contested matter with multiple hearings.
If you cannot afford the filing fee, you can ask the court to waive it by filing an affidavit of inability to pay. Texas courts routinely grant fee waivers for individuals who demonstrate financial hardship.
