How to Establish Paternity in Georgia
Reviewed by DocDraft Legal Team · Georgia · Last updated 2026-09-12
In Georgia, establishing paternity is the legal step that names a child's father so the child qualifies for support, custody and visitation, inheritance, insurance, and benefits. Parents who agree can complete a Paternity Acknowledgment, Form 3940, which when signed and filed with the State Office of Vital Records is a legal determination of paternity (O.C.G.A. 19-7-46.1). Two Georgia rules stand out. First, timing: Georgia sets no statutory statute of limitations to bring a court action to establish paternity, so a petition under O.C.G.A. 19-7-43 may be filed at any time by the child, the mother, a relative caring for the child, the alleged father, or the Division of Child Support Services. Second, the genetic-testing threshold: scientifically credible testing that shows at least a 97 percent probability of paternity creates a rebuttable presumption of paternity, which can be overcome only by clear and convincing evidence (O.C.G.A. 19-7-46(c)). A child born in wedlock is presumed legitimate, and where possibility of access exists that presumption is strong and the proof to the contrary must be clear (O.C.G.A. 19-7-20).

How long do I have to establish paternity in Georgia?
Georgia sets no statutory deadline to bring a court action to establish paternity. A petition under O.C.G.A. 19-7-43 may be filed at any time by the child, the mother, a relative caring for the child, the alleged father, or the Division of Child Support Services, and a voluntary acknowledgment can also be signed at any time.
What is the marital presumption of paternity in Georgia?
Under O.C.G.A. 19-7-20, all children born in wedlock or within the usual period of gestation are legitimate. Where the husband had possibility of access, the presumption in favor of legitimacy is strong, and a party disputing it must present clear evidence, meaning clear and convincing proof, to establish the contrary.
What genetic test result establishes paternity in Georgia?
Under O.C.G.A. 19-7-46(c), scientifically credible genetic testing that shows at least a 97 percent probability of paternity creates a rebuttable presumption that the man is the father. That presumption can be overcome only by clear and convincing evidence presented to the trier of fact.
Who handles paternity cases in Georgia?
The Georgia Division of Child Support Services, part of the Department of Human Services, helps parents establish paternity and support. Parents can sign a Paternity Acknowledgment filed with the State Office of Vital Records, and contested cases are decided by the superior court, which can order genetic testing.
Georgia paternity law at a glance
Georgia keeps the door open longer than most states: there is no statutory statute of limitations to bring a court action to establish paternity, so a petition under O.C.G.A. 19-7-43 may be filed at any time by the child, the mother, a caregiver relative, the alleged father, or the Division of Child Support Services. Parents who agree can instead complete a Paternity Acknowledgment, Form 3940, which when filed with the State Office of Vital Records is a legal determination of paternity (O.C.G.A. 19-7-46.1). Genetic testing is decisive here, because scientifically credible testing showing at least a 97 percent probability of paternity creates a rebuttable presumption that can be overcome only by clear and convincing evidence (O.C.G.A. 19-7-46(c)). A child born in wedlock is presumed legitimate, and where the husband had possibility of access the presumption is strong (O.C.G.A. 19-7-20).
Establishing Georgia paternity years after the child's birth
Suppose a father in Georgia wants to establish paternity of a child who is already several years old. Because Georgia sets no statute of limitations, he can file a petition to establish paternity in the superior court at any time under O.C.G.A. 19-7-43, and the Division of Child Support Services can also open a case. The court orders genetic testing, and a result showing at least a 97 percent probability of paternity creates a rebuttable presumption that he is the father, overcome only by clear and convincing evidence (O.C.G.A. 19-7-46(c)). Had the parents agreed at birth, they could have signed a Paternity Acknowledgment, Form 3940, filed with the State Office of Vital Records as a legal determination of paternity (O.C.G.A. 19-7-46.1), with a 60-day right to rescind. Attorney review is available through DocDraft.

Regional Variances
Georgia paternity rules at a glance
Voluntary path and form
Parents who agree complete a Paternity Acknowledgment, Form 3940, filed with the State Office of Vital Records, which is a legal determination of paternity under O.C.G.A. 19-7-46.1.
Rescission window
A signer may rescind the acknowledgment within 60 days of signing, or before a judicial or administrative proceeding relating to the child if earlier. After that it can be challenged only for fraud, duress, or material mistake of fact.
Marital presumption
Children born in wedlock are presumed legitimate, and where the husband had possibility of access the presumption is strong and must be overcome by clear and convincing evidence (O.C.G.A. 19-7-20).
Deadline to establish
Georgia sets no statutory statute of limitations to bring a paternity action, so a petition under O.C.G.A. 19-7-43 may be filed at any time, unlike states that cap the action at a child's age.
Genetic-testing threshold
Scientifically credible testing showing at least a 97 percent probability of paternity creates a rebuttable presumption of paternity, overcome only by clear and convincing evidence (O.C.G.A. 19-7-46(c)).
Paternity versus legitimation
Establishing paternity supports child support, while legitimation is a separate superior court process that grants a father full parental rights, so a father may need to pursue both.
Suggested Compliance Checklist
Confirm whether the child was born in wedlock
Before signing or filing anything days after startingDetermine whether the mother was married when the child was born, which makes the child presumed legitimate and the husband the legal father (O.C.G.A. 19-7-20). Where possibility of access exists, that presumption is strong and must be overcome by clear and convincing evidence.
Get genetic testing if paternity is uncertain
Before acknowledging paternity days after startingIf there is doubt, obtain genetic testing first. Under O.C.G.A. 19-7-46(c), scientifically credible testing showing at least a 97 percent probability of paternity creates a rebuttable presumption of paternity that can be overcome only by clear and convincing evidence.
Complete and file the Paternity Acknowledgment
At the hospital or a local office days after startingParents who agree sign the Paternity Acknowledgment, Form 3940, and file it with the State Office of Vital Records, where it is a legal determination of paternity (O.C.G.A. 19-7-46.1). 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 within 60 days of signing, or before a judicial or administrative proceeding relating to the child if earlier. After 60 days it can be undone only for fraud, duress, or material mistake of fact.
File a paternity petition if parents disagree
Any time a dispute arises days after startingIf parents do not agree, file a petition to establish paternity in superior court under O.C.G.A. 19-7-43, or ask the Division of Child Support Services to open a case. Because Georgia sets no deadline, the petition may be filed at any time, and the court can order genetic testing.
Consider whether legitimation is also needed
Before relying on custody rights days after startingEstablishing paternity supports child support but does not by itself grant a father full parental rights. Ask whether a separate legitimation petition is needed to secure custody and visitation standing, and keep records of every filing and order.

Frequently Asked Questions
Establishing paternity in Georgia is the legal step that names a child's father so the child qualifies for support, custody and visitation, inheritance, insurance, and benefits. It can be done with a Paternity Acknowledgment or through a court petition to establish paternity (O.C.G.A. 19-7-46.1, 19-7-43).
Parents who agree complete a Paternity Acknowledgment, Form 3940, filed with the State Office of Vital Records, which is a legal determination of paternity (O.C.G.A. 19-7-46.1). If parents disagree, file a petition in superior court under O.C.G.A. 19-7-43, and the Division of Child Support Services can also help.
It is a form, Form 3940, that parents sign to name the child's legal father without a court hearing. When signed and filed with the State Office of Vital Records it is a legal determination of paternity under O.C.G.A. 19-7-46.1 and can support a child support order.
No. Georgia sets no statutory statute of limitations to bring a court action to establish paternity, so a petition under O.C.G.A. 19-7-43 may be filed at any time by the child, the mother, a caregiver relative, the alleged father, or the Division of Child Support Services.
A child born in wedlock is presumed legitimate under O.C.G.A. 19-7-20. Where the husband had possibility of access, the presumption is strong and a party disputing it must present clear and convincing evidence, often including genetic testing, to establish that he is not the father.
Yes, within a limited window. A signer may rescind a paternity acknowledgment within 60 days of signing, or before a judicial or administrative proceeding relating to the child if that is earlier. After 60 days it can be set aside only for fraud, duress, or material mistake of fact.
Not by itself. Under O.C.G.A. 19-7-46(c), scientifically credible testing showing at least a 97 percent probability of paternity creates a rebuttable presumption of paternity, but paternity is finalized by a signed acknowledgment or a court order, not the lab report alone.
No. Establishing paternity identifies the biological father and supports child support, while legitimation is a separate court process that gives the father full parental rights, including custody and visitation standing. A father may need both, so consider whether a legitimation petition is also required.
