In Tennessee, unmarried fathers are required to establish paternity prior to attempting to exercise parental rights. This guide covers how paternity gets established in Tennessee, the state process involved, and what rights fathers have once it’s completed .
This guide is part of our broader guide to family law in Tennessee and pairs closely with our guides to child custody and child support, since establishing paternity is usually the first legal step before either of those becomes enforceable for an unmarried father.

Paternity is the legal determination of who a child’s father is. It matters for a lot of reasons that go beyond just confirming biology:
If a child’s parents are married when the child is born, Tennessee law generally presumes the husband is the legal father. If the parents aren’t married, paternity has to be established through one of the specific processes described below.
Tennessee’s paternity laws are found in Title 36, Chapter 2 of the Tennessee Code, often referred to as Tennessee’s parentage law. This body of law covers:
Including the presumption that applies when a child is born to married parents.
The process for both parents to acknowledge paternity at the time the child is born.
Used when paternity is contested or unknown.
To legally establish the father when the parents are not married at the time the child is born.
The legal rights and responsibilities that follow once paternity is established, including custody, visitation, and support.
There are generally two paths to establishing paternity in Tennessee.
If both parents agree on who the father is, they can sign a Voluntary Acknowledgment of Paternity, a legal form that acknowledges paternity at the time the child is born. This is often done right at the hospital after the baby is born, but it can also be completed later through the Tennessee Department of Human Services’ paternity establishment process. Once properly signed and filed, a VAP has the same legal effect as a court order establishing paternity. There’s generally a limited window during which either parent can rescind (cancel) the acknowledgment if they change their mind, so it’s worth understanding that window before signing. It’s important to note, though, that a VAP alone does not automatically grant the father any custodial or visitation rights. This still must be done through a court order.
This might involve filing a petition to establish parentage, either by a parent or, in some cases, by the Tennessee Department of Human Services, if a parent has applied for child support services. Genetic testing is not required but can be ordered by the court or the state agency if paternity is disputed or unknown. A court order formally establishes legal paternity.
A lot of paternity cases in Tennessee actually move through the Department of Human Services’ Child Support Services division rather than starting as a standalone court case. This often happens when a parent applies for child support services, since establishing paternity is typically a required first step before support can be ordered.
Submitting an application for services, if you haven’t already connected with the agency.
Identifying the alleged father, so the agency can begin the process of establishing paternity.
Genetic testing, if needed, which the agency can arrange and, in many cases, help facilitate.
A legal determination of paternity, either through a voluntary acknowledgment or a court order.
This state agency process can be a lower-cost path for parents who might not otherwise be able to afford a private attorney to establish paternity on their own.
Once paternity is legally established and a Parenting Plan has been entered, yes. When a child is born to unmarried parents, the mother automatically has sole legal and physical custody in Tennessee until the father has established his paternity and petitioned the court for custody or parenting time. Once a father has been legally established, the court does not have a legal preference for one parent over the other based on gender. That includes the right to seek custody or parenting time, the right to have input on major decisions affecting the child, and the right to notice if certain legal proceedings involving the child, like an adoption, come up later. Without established paternity, though, an unmarried father generally doesn’t have enforceable rights to any of this.
This is the prerequisite, and without it, there is no legal parent-child relationship for a court to recognize.
This formally asks the court to determine custody, parenting time, and decision-making authority.
This might include the father’s relationship with the child, involvement in the child’s life, ability to provide a stable home, and other factors covered in our guide to child custody in Tennessee.
Many Tennessee counties require this step before a contested custody case can go to trial.
Once the court decides (or the parents reach an agreement), the resulting parenting plan becomes a binding, enforceable order.
When paternity is disputed or simply unknown, genetic (DNA) testing is often the deciding factor. Generally:
Testing can be ordered by a court or arranged through the state agency process, when paternity is contested.
It typically involves a simple cheek swab or blood sample from the child and the alleged father.
Results are highly accurate, and a positive result generally leads directly to a legal determination of paternity.
Cost responsibility varies, sometimes assigned to the party requesting the test, depending on the results.
Establishing paternity often leads directly to other family law matters.

In some circumstances, yes, often through genetic testing of other relatives or existing evidence, though this process is more complex and typically requires court involvement.
She isn't required to identify a father to give birth or raise her child, but if she applies for state child support services, establishing paternity is generally part of that process.
Only within a very short window of time after signing, or before a related court proceeding, whichever comes first. After that window closes, undoing it generally requires a stronger legal basis, like fraud or duress.
No, establishing paternity confirms the legal parent-child relationship; but custody and parenting time still have to be requested and decided, usually through a parenting plan, unless one is already in place.
Whether you’re a father wanting to secure your legal rights, or a mother trying to establish support, getting paternity right is the foundation everything else builds on.
