A DNA test is not always required to set child support in Georgia. Whether a DNA test for child support in Georgia is ordered depends on one thing: whether the child already has a legal father. If a man is recognized as the father through marriage or a signed voluntary acknowledgment, the state skips testing and moves straight to calculating support. If no legal father is on record, the Division of Child Support Services (DCSS) has to order genetic testing before any support obligation can be set.
When You Can Skip the Test
Georgia recognizes paternity without a swab in two situations.
The first is marriage. If the parents were married when the child was born, the husband is legally presumed to be the father. Under O.C.G.A. § 19-7-20, children born during a marriage are considered legitimate, and the presumption in favor of the husband is strong whenever he had access to the mother during the relevant period.1Justia Law. Georgia Code 19-7-20 – Circumstances of Legitimacy; Disproving Legitimacy; Legitimation by Marriage of Parents and Recognition of Child Testing only enters the picture if someone files a legal action to challenge that presumption, and the proof needed to overcome it is high.
The second is a Voluntary Paternity Acknowledgment. Hospitals are required to offer unmarried parents this form after a birth whenever a notary is available.2Justia Law. Georgia Code 19-7-27 – Hospital Program for Establishment of Paternity It can also be signed later at the State Office of Vital Records, a county Vital Records office, or anywhere else a notary can witness both signatures.3Georgia Department of Human Services. Paternity Establishment Frequently Asked Questions Once signed, the father’s name goes on the birth certificate and the acknowledgment carries the same legal weight as a court order for paternity.
Either parent has 60 days from signing to rescind the acknowledgment. After that, it becomes a legal determination of paternity and can only be challenged by proving fraud, duress, or a material mistake of fact, with the burden on the person challenging it.4Georgia Department of Human Services Division of Child Support Services. Paternity Establishment Even a timely rescission still requires a court order to remove the father’s name from the birth certificate.
When a DNA Test Is Required
When no legal father exists, testing is on. Since July 1, 2015, DCSS has been required by law to conduct paternity testing in every newly established child support case where paternity has not already been determined.5Georgia Department of Human Services Division of Child Support Services. Paternity Establishment The agency does not have discretion to skip it.
Outside of DCSS cases, either parent can ask the court to order testing. A mother filing a paternity and child support action typically requests it in the petition. An alleged father named in such a lawsuit can request it in his response. Under O.C.G.A. § 19-7-45, the court can order the mother, alleged father, and child to submit to genetic tests.6Justia Law. Georgia Code 19-7-45 – Genetic Tests
How the Test Actually Happens
Two routes lead to a legally admissible result: filing in Superior Court or going through DCSS.
In the court route, a parent files a Petition to Establish Paternity and Child Support in the Superior Court of the county where the other parent lives, and the petition includes a request for genetic testing. If the judge grants it, the order directs all parties to submit samples at an approved facility.
In the DCSS route, the agency handles the logistics. DCSS schedules appointments at an approved facility and mails official notices with the date, time, and location for sample collection. It tends to be the simpler path because the agency manages coordination and paperwork.
The collection itself is identical either way. Each person shows ID and gives a buccal swab, a quick cheek swab, under a chain-of-custody protocol so the results hold up in court. Results typically reach the parties through the court system in four to six weeks, though the lab work itself is faster.
If the alleged father lives in another state, collection still happens. Certified labs routinely coordinate interstate sample collection, and it rarely requires help from the other state’s child support agency. When someone actively resists or repeatedly fails to appear, the state that initiated the case can request limited enforcement help from the other state.
What It Costs and Who Pays
Through DCSS, the fee is $40 per person. For the standard three-person test covering mother, alleged father, and one child, that comes to $120. DCSS fronts the cost and gets reimbursed later. If the man is confirmed as the biological father, he pays. If he is excluded, the mother who applied for services pays. DCSS waives the fee entirely for mothers receiving TANF or Family Medicaid, grandparents raising grandchildren, and other third-party custodians.5Georgia Department of Human Services Division of Child Support Services. Paternity Establishment
Court-ordered testing outside DCSS costs more because private labs set their own prices. Under O.C.G.A. § 19-7-49, the court can award the cost of genetic testing as part of its final order, so the judge decides who ultimately pays.7Justia Law. Georgia Code 19-7-49 – Final Order; Effect
What Happens If Someone Refuses
Ignoring a court-ordered genetic test is a serious mistake. The order is enforceable by contempt, which can mean fines or jail.6Justia Law. Georgia Code 19-7-45 – Genetic Tests A judge can also treat the refusal as evidence and rule on paternity using whatever information is available, which in practice often means a default finding of paternity against a man who never provided a sample.
It cuts both ways. If the mother or petitioner refuses testing, the court can dismiss the entire paternity action on the respondent’s motion.6Justia Law. Georgia Code 19-7-45 – Genetic Tests Refusing to cooperate with testing you asked for will end your case.
What the Results Mean
Results go directly to the court or DCSS. If the test shows at least a 97 percent probability of paternity, Georgia law creates a rebuttable presumption that the man is the father. Overcoming that presumption requires clear and convincing evidence.8Justia Law. Georgia Code 19-7-46 – Evidence at Trial In most cases, a result at or above 97 percent produces a final order of paternity and the case moves to calculating support.
If the test excludes the man, the case against him ends. The court issues an order declaring he is not the father, and the pending child support action is dismissed.
A Warning for Unmarried Fathers
Establishing paternity by DNA test or court order does not give an unmarried father custody or visitation. It only establishes his obligation to pay support. Without a separate legal step called legitimation, the mother has sole custody and the father has no enforceable right to see his child.9Georgia Courts. Legitimation
Georgia is blunt about what does not count as legitimation: being named as the father on a paternity test, agreeing to pay child support, signing the birth certificate, and even naming the child in a will are all insufficient.9Georgia Courts. Legitimation Without legitimation, the child also cannot inherit from the father, and the father cannot inherit from the child.10Child Support Commission. Legitimation Information for Fathers
To legitimize the relationship, the father files a petition for legitimation in the superior court of the county where the mother or legal custodian lives, and he can ask for visitation or custody in the same petition.11Justia Law. Georgia Code 19-7-22 – Petition for Legitimation of Child Marrying the child’s mother is the only other path. For an unmarried father who wants a real legal relationship with his child, legitimation is the next step after the paternity question is resolved.
