How to Establish Paternity in Tennessee: Acknowledgment, Court, and DNA

There are two ways to establish paternity in Tennessee: both parents can sign a Voluntary Acknowledgment of Paternity, or a court can enter a parentage order after a legal proceeding. Which path fits depends on whether the parents agree on who the biological father is. One situation skips both: if the mother is married when the child is born, or was married and the child arrives within 300 days of that marriage ending by death, annulment, or divorce, her husband is presumed to be the father automatically, and no form or filing is needed unless someone challenges that presumption.¹

Signing a Voluntary Acknowledgment of Paternity

When the parents are unmarried and agree on who the father is, the simplest route is the Voluntary Acknowledgment of Paternity (VAoP). It establishes paternity without a courtroom.²

Parents can sign at the hospital shortly after birth. If that moment passes, the form can be completed at a local health department office instead. It must be a sworn affidavit and include both parents’ Social Security numbers.³ A minor parent can sign, but only with a parent or legal guardian present and consenting at the time of signing.

Once the Office of Vital Records receives the signed form, the father’s name is added to the child’s birth certificate. The parents can also choose to give the child the father’s surname. A completed VAoP is conclusive proof of paternity under Tennessee law and carries the same legal weight as a court order, so it can serve on its own as the basis for a child support order without further proceedings.⁴

One warning. If either parent has any doubt about who the biological father is, do not sign the VAoP. Get DNA testing first. The form is binding, and the window to walk it back is short.

The 60-day rescission window

Either parent who signed a VAoP can rescind it within 60 days of the date of signing, no reason required. The Office of Vital Records will amend the birth certificate once it receives a rescission filed within that window.⁴

After 60 days, the only way out is a court challenge, and the person seeking rescission has to prove fraud (by misrepresentation or concealment), duress, or a material mistake of fact. If the court grants rescission on one of those grounds, Vital Records will amend the birth certificate accordingly.⁴ Outside those narrow grounds, the acknowledgment stands.

Filing a Parentage Case in Court

When the parents disagree, or no presumption applies and no VAoP is signed, the next step is a court action. Tennessee law calls it a “complaint to establish parentage.” The people who can file one are:

The child, through a guardian or next friend if a minor, or directly after reaching the age of majority
The child’s mother
A man who believes he is the father
The Tennessee Department of Human Services or its contractor

The complaint can be filed in juvenile court or any trial court with general jurisdiction.⁵ Venue is the county where the father lives or is found, where the mother lives or is found, or where the child lives or is present. Tennessee courts have statewide jurisdiction over parents in paternity cases, and any contact with Tennessee that resulted in the conception of a child born outside marriage is enough to bring an out-of-state parent under a Tennessee court’s authority.⁶

After filing, the other party has to be formally served, the same as in any civil lawsuit. One procedural detour: if an adoption petition has already been filed for the same child, the paternity complaint has to be filed in the court handling the adoption, and any paternity case already pending elsewhere gets transferred there on motion of any party.⁶

DNA Testing and the 95 Percent Threshold

DNA testing is the center of most contested cases. Courts routinely order it. When results show a 95% or greater statistical probability that the man is the father, Tennessee law creates a rebuttable presumption of paternity, and the case proceeds to a bench trial, with no jury, on the paternity question.⁷

A legal-grade, chain-of-custody DNA test typically costs between $350 and $475. This is not the same as an at-home curiosity kit sold online for under $100. Court-admissible testing requires samples collected at an approved facility and tracked from collection through analysis. If the court orders testing, it decides who pays, though costs are frequently assigned to the party who requested the test or split between the parties.

When results exceed the 95% threshold, the presumption alone is often enough for the court to enter a paternity order. The alleged father can still try to rebut the presumption, but successful challenges to results above 99% are extraordinarily rare.

Other Ways Tennessee Already Presumes Paternity

Beyond the marital presumption, Tennessee law treats a man as the presumed father in a few other situations. He and the mother attempted to marry before the child was born, even if the marriage turns out to be invalid. They married or attempted to marry after birth, and he either acknowledged paternity in writing, consented to being named on the birth certificate, or is paying court-ordered support. He took the child into his home and openly treated the child as his own while the child was still a minor. Or genetic testing shows a 95% or greater statistical probability of paternity.¹

All of these presumptions are rebuttable in court, and the standard for rebutting a presumption is a preponderance of the evidence.⁸ Until someone challenges one, the presumed father carries all the legal rights and obligations of a parent.

What Establishing Paternity Gives the Child and the Father

Legal paternity unlocks rights that don’t exist without it. Child support is the most immediate. Tennessee uses an income shares model, combining both parents’ incomes to determine a basic obligation and assigning each parent a proportional share based on earnings; a mandatory worksheet produces the final amount, with adjustments for parenting time.⁹ Orders typically also address health insurance and uncovered medical costs, and in cases enforced through the state’s Title IV-D program the court is required to enter an order addressing health coverage for the child.¹⁰

Establishing paternity does not by itself hand the father custody or a visitation schedule. It gives him standing to ask for them. A separate parenting plan, decided by the court based on the child’s best interest, sets where the child lives, how time is divided, and how major decisions are made.¹¹

Paternity also controls inheritance. Without it, a child born outside marriage has no automatic right to inherit from the father. If the father dies before paternity is established, it can still be proven after death, but the standard rises to clear and convincing evidence and the claim has to be filed within the earlier of the period in the estate’s published notice to creditors or one year after the father’s death. That timeline is one of the strongest practical reasons to establish paternity sooner rather than later.

Federal benefits follow the same logic. A child with established paternity can qualify for Social Security benefits on the father’s record, including survivor benefits if the father dies and benefits if the father becomes disabled. The Social Security Administration determines eligibility by looking at whether the child could inherit under state law, whether the father acknowledged the child in writing, or whether a court established paternity. The SSA will not enforce any state time limit measured from the father’s death or the child’s birth, and it applies whichever version of state law in effect between the first month of eligibility and the final decision is most favorable to the child.¹²

Protecting a Possible Father’s Rights: The Putative Father Registry

Tennessee maintains a putative father registry through the Department of Children’s Services. Any man who believes he may have fathered a child can file a written notice of intent to claim paternity. The filing has to happen either before the child’s birth or within 30 days after birth.¹³

The registry’s main function is adoption-related. If a man is listed, anyone seeking to adopt the child must notify him of the adoption proceedings and either obtain his consent or have his parental rights formally terminated before the adoption can proceed. A man who fails to register has no guarantee of receiving notice, and an adoption can go forward without him.¹³ For any unmarried man who thinks he may have fathered a child and is worried about adoption, the 30-day deadline is strict, and missing it can forfeit the right to be heard.

Help From the Department of Human Services

You don’t have to go through this alone. The Tennessee Department of Human Services runs a child support program that assists with establishing paternity directly. The local child support office can schedule DNA testing through a certified lab, and once results come back positive, the office works to establish paternity through a court order.¹⁴ DHS can also file its own complaint to establish parentage on behalf of the state, which typically happens when the custodial parent is receiving public assistance.⁵

If you’re working with DHS, both parents should attend every scheduled court hearing. Not showing up can result in a default judgment, meaning the court may establish paternity and set a support order without your input.
