How to Establish Paternity in Tennessee
Reviewed by DocDraft Legal Team · Tennessee · Last updated 2026-09-12
In Tennessee, establishing parentage means legally identifying a child's father so the child gains rights to support, custody and visitation, health coverage, inheritance, and benefits. There are two main paths. Unmarried parents who agree can sign a Voluntary Acknowledgment of Paternity, which is a legal finding of paternity that adds the father to the birth certificate. Either parent generally has 60 days to rescind, and after that federal window it can be challenged only for fraud, duress, or a material mistake of fact (42 U.S.C. 666(a)(5)). When parents do not agree, a court decides parentage and can order genetic testing. Tennessee's load-bearing timing rule is generous: an action to establish parentage may be instituted before or after the child's birth and until three years beyond the child's age of majority, so effectively until the child turns 21 (Tenn. Code Ann. 36-2-306). A man married to the mother when the child is born, or within 300 days after the marriage ends, is rebuttably presumed the father; the standard to rebut is a preponderance of the evidence, though a narrow 12-month deadline applies when a married couple living together both swear the husband is the father (Tenn. Code Ann. 36-2-304). Genetic testing showing a 95 percent or greater probability creates a rebuttable presumption of paternity (Tenn. Code Ann. 24-7-112).

How do I establish paternity in Tennessee?
There are two routes. Unmarried parents who agree can sign a Voluntary Acknowledgment of Paternity, a legal finding of paternity that adds the father to the birth certificate. If parents disagree, a court decides parentage under Tenn. Code Ann. 36-2-306 and can order genetic testing before entering an order.
How long do I have to establish paternity in Tennessee?
Tennessee allows a long window. Under Tenn. Code Ann. 36-2-306, an action to establish parentage may be brought before or after birth and until three years beyond the child's age of majority, so effectively until the child turns 21. Acting early still protects support and inheritance rights.
What is the marital presumption of paternity in Tennessee?
Under Tenn. Code Ann. 36-2-304, a man married to the mother when the child is born, or within 300 days after the marriage ends, is rebuttably presumed the father. The standard to rebut is a preponderance of the evidence, and a special 12-month deadline applies when a married couple both swear the husband is the father.
What genetic-testing result establishes paternity in Tennessee?
Under Tenn. Code Ann. 24-7-112, genetic testing showing a 95 percent or greater statistical probability creates a rebuttable presumption of paternity. At 99 percent or greater, the putative father can rebut only by clear and convincing evidence of a narrow defense such as sterility.
Tennessee paternity law at a glance
Tennessee lets unmarried parents establish parentage without court by signing a Voluntary Acknowledgment of Paternity, a legal finding of paternity that adds the father to the birth certificate; either parent generally has 60 days to rescind. The state's timing rule is generous: an action to establish parentage may be brought before or after birth and until three years beyond the child's age of majority, so until the child turns 21 (Tenn. Code Ann. 36-2-306). A man married to the mother when the child is born is rebuttably presumed the father, rebuttable by a preponderance of the evidence, though a 12-month deadline applies when a married couple both swear he is the father (Tenn. Code Ann. 36-2-304). Genetic testing at 95 percent creates a rebuttable presumption, and at 99 percent the putative father can rebut only by clear and convincing evidence of a narrow defense (Tenn. Code Ann. 24-7-112).
Establishing Tennessee parentage for a child born to unmarried parents
Consider a child born in Tennessee to unmarried parents who agree on the father. At the hospital both sign a Voluntary Acknowledgment of Paternity, a legal finding of paternity. If a parent reconsiders, either may rescind within 60 days (42 U.S.C. 666(a)(5)); after that it stands unless fraud, duress, or a material mistake is proven. Had parentage been disputed, either could ask the court to order genetic testing, where a 95 percent probability creates a rebuttable presumption and 99 percent leaves only a narrow clear-and-convincing defense (Tenn. Code Ann. 24-7-112); such an action may be brought until three years past the child's majority (Tenn. Code Ann. 36-2-306). Had the mother been married and living with her husband, and both swore he is the father, any action to name another man must be brought within 12 months of birth (Tenn. Code Ann. 36-2-304).

Suggested Compliance Checklist
Confirm whether a marital presumption applies
Before signing or filing anything days after startingDetermine whether the mother was married when the child was born or within 300 days after the marriage ended, which triggers Tennessee's rebuttable presumption that the husband is the father (Tenn. Code Ann. 36-2-304), and watch for the special 12-month deadline.
Get genetic testing if biological parentage is uncertain
Before signing an acknowledgment days after startingBecause the acknowledgment is a legal finding of paternity, obtain genetic testing first if there is any doubt. Under Tenn. Code Ann. 24-7-112, results of 95 percent or greater create a rebuttable presumption of paternity.
Sign the Voluntary Acknowledgment of Paternity
At the hospital or a child support office days after startingUnmarried parents who agree sign a Voluntary Acknowledgment of Paternity, a legal finding of paternity that adds the father to the birth certificate. Keep a copy. Attorney review of your paternity matter is available through DocDraft.
Track the 60-day rescission window
Within 60 days of signing days after startingIf you need to cancel a signed acknowledgment, rescind it within 60 days under federal law (42 U.S.C. 666(a)(5)). After that it can be challenged only for fraud, duress, or a material mistake of fact.
File a parentage action in time if parents disagree
Until three years past the child's majority days after startingIf parents do not agree, file to establish parentage; the court can order genetic testing. Under Tenn. Code Ann. 36-2-306 the action may be brought until three years past the child's majority, but the 12-month marital rule of 36-2-304 can cut that short.
Keep records of the acknowledgment, testing, and orders
Ongoing days after startingSave copies of the signed acknowledgment, any genetic-test results, and court papers, and calendar the 60-day rescission window and any 12-month presumption deadline (Tenn. Code Ann. 36-2-304) so you do not miss a right-forfeiting date.
