Establishing Paternity in Tennessee
For unmarried parents in Tennessee, legal parentage is established under the parentage statutes (T.C.A. § 36-2-301 et seq.) — either by a Voluntary Acknowledgment of Paternity or by a court petition with genetic testing. A genetic test showing 95% or greater probability creates a presumption of parentage (T.C.A. § 24-7-112). Establishing paternity is the gateway to custody, parenting time, and child support.

When a child’s parents are not married, the father isn’t automatically a legal parent — parentage has to be established. Tennessee’s parentage statutes are at T.C.A. § 36-2-301 et seq.
Two ways to establish parentage
- Voluntary Acknowledgment of Paternity (VAoP). Both parents sign a form (administered through TN DHS), which establishes legal fatherhood and puts the father on the birth certificate. It’s the simplest route when both parents agree.
- Petition to establish parentage. Either parent (or the State) files a court case. If paternity is disputed, the court can order genetic testing. A test showing 95% probability or greater creates a presumption of parentage (T.C.A. § 24-7-112).
Why it’s the gateway
Establishing paternity is what unlocks the legal rights and duties of a parent:
- A father can seek custody and parenting time (a parenting plan).
- The court can order child support.
- The child gains rights such as inheritance and access to the father’s benefits.
A word of caution: signing a VAoP is a legal finding of parentage with limited time to rescind, so if you’re unsure, ask for genetic testing first. To get matched with a local Tennessee attorney, connect with a lawyer.

- How do unmarried parents establish legal fatherhood in Tennessee?
- Two main ways: by signing a Voluntary Acknowledgment of Paternity (through TN DHS), or by a court order establishing parentage — often with genetic testing if paternity is disputed (T.C.A. § 36-2-301 et seq.).
- Why does establishing paternity matter?
- It's the legal prerequisite to seeking custody and parenting time, and to ordering child support. Without established parentage, an unmarried father generally has no enforceable rights or obligations.
- What if there's doubt about who the father is?
- Don't sign the acknowledgment — request genetic testing. A result showing 95% probability or greater creates a legal presumption of parentage (T.C.A. § 24-7-112).

- Adoption in Tennessee Tennessee adoption law is in Title 36, Chapter 1. Before an adoption can be finalized, the existing parental rights must be surrendered or terminated (T.C.A. § 36-1-113), and a home study/court report is generally part of the process. Common types include stepparent, relative, agency, and private adoptions.
- Family Law Mediation in Tennessee Tennessee courts are directed to order mediation in many contested divorces (T.C.A. § 36-4-131), with exceptions including domestic violence, inability to afford it, or an already-signed agreement. Family mediators are commonly Rule 31 listed mediators under Tennessee Supreme Court Rule 31. Mediation lets parents and spouses craft their own resolution instead of leaving it to a judge.
- Grandparents' Visitation Rights in Tennessee Tennessee's grandparent visitation statute (T.C.A. § 36-6-306) is deliberately narrow. A grandparent can petition only in specific situations — such as a parent's death, the parents' divorce or separation, or a severed long-standing relationship — and the court must find a danger of substantial harm to the child. The limits reflect the constitutional rights of fit parents under Troxel v. Granville (2000).
- Postnuptial Agreements in Tennessee Tennessee enforces postnuptial agreements under case law — principally Bratton v. Bratton (Tenn. 2004) — rather than a dedicated statute. To be enforceable, a postnup needs adequate consideration flowing to both spouses, knowing and voluntary execution, and no fraud, coercion, or duress. The consideration requirement is what makes postnups harder to uphold than prenups.
- Prenuptial Agreements in Tennessee Tennessee enforces prenuptial (antenuptial) agreements under T.C.A. § 36-3-501 if they were entered into freely, knowledgeably, and in good faith, and without duress or undue influence. A prenup can define how property and support are handled if the marriage ends, but a court can refuse to enforce one that was signed under unfair circumstances.
- Separation Agreements & Legal Separation in Tennessee In a Tennessee divorce, the Marital Dissolution Agreement (MDA) is the contract that settles property, debts, and support, and it's incorporated into the decree — it's required for a no-fault (irreconcilable differences) divorce. Separately, Tennessee allows legal separation under T.C.A. § 36-4-102: the marriage stays intact, but the court can still order custody, support, and property arrangements.
