How Paternity Is Established in Ohio

Ohio recognizes three methods for legally establishing paternity, and the right path depends on whether both parents agree and the circumstances of the case.

Acknowledgment of Paternity Affidavit

When both parents agree on paternity, they can sign an Acknowledgment of Paternity Affidavit at the hospital at birth or later at the local registrar or the Child Support Enforcement Agency in the mother’s county of residence. Once signed and finalized by both parents, this affidavit carries the same legal weight as a court order under Ohio Revised Code 3111.25. One important point: signing a birth certificate alone does not establish legal paternity in Ohio. It’s a common misconception that can leave a father without enforceable rights despite appearing on the document.

Administrative Order Through the CSEA

When parents disagree, the Franklin County Child Support Enforcement Agency can administer genetic testing. If results show a 99% or greater probability of parentage, the agency can issue an administrative paternity order without a court filing. This path can be faster than litigation when a biological question is in dispute, but both parties cooperate with testing.

Court Order Through Franklin County

Paternity can also be established by filing a petition in the Franklin County Court of Common Pleas, Juvenile Division, which handles paternity matters for unmarried parents. When paternity is disputed within a divorce proceeding, the Domestic Relations Division may have jurisdiction instead. If a potential father refuses to participate in testing, or a mother won’t cooperate, the court can compel compliance through the petition process.

Parenting Time in Franklin County After Paternity Is Established

Securing custody or parenting time requires a separate court order from the Franklin County Court of Common Pleas. For unmarried fathers in Columbus, the court generally applies a model parenting time schedule as its baseline, one that typically includes time every other weekend, one weekday evening, and portions of summer and holidays.

That schedule is a starting point, not a guaranteed outcome. Courts can adjust it based on the best interests of the child, including each parent’s relationship with the child, the child’s adjustment and health, and any safety considerations. Shared parenting arrangements are also available in Franklin County when both parents are willing to develop and follow a shared parenting plan. Existing custody and parenting time orders can be modified later if a significant change in circumstances affects the child’s best interests.

Contesting Paternity in Ohio

Not every paternity determination is final. Ohio law allows a man to challenge paternity even if he is listed on the birth certificate or previously signed an acknowledgment, but time limits apply and delay can close off available options. Courts typically order genetic testing when a challenge is filed. If results show the listed father isn’t the biological father, the court may set aside a prior acknowledgment or court order.

A man who has been raising a child he didn’t father has legal options under Ohio law, but acting promptly matters. Mothers may also need to challenge or correct a paternity determination if the wrong person was acknowledged, particularly when support orders and custody rights are affected. Consulting a paternity lawyer in Columbus as soon as questions arise can give you the clearest picture of what’s possible.
