By Andrew Russ, Ohio Father’s Rights Attorney
Quick Take
- In Ohio, paternity can be established by Acknowledgment of Paternity Affidavit or by genetic testing leading to an administrative or court order.
- A legal finding of paternity unlocks parenting time, decision-making rights, access to records, and ensures the child’s eligibility for support and benefits.
- Questions or disputes about paternity are commonly resolved with DNA testing (≥99% probability) through the county CSEA or the court.
Why Paternity Matters for Ohio Fathers
Until paternity is legally established for unmarried parents, a child does not have a legal father—which can limit the father’s rights and a child’s benefits. Once paternity is established, fathers can pursue custody or parenting time, participate in major decisions, and ensure children access insurance, Social Security, military benefits, and accurate medical history.
Two Primary Ways to Establish Paternity in Ohio
1) Acknowledgment of Paternity Affidavit (AOP)
• Voluntary form signed by both parents—at the hospital after birth or later at a health department or CSEA office.
• Fastest route to add the father’s name to the birth certificate and legally establish parentage.
• Do not sign if there’s any doubt—consider testing first.
Basic requirements: IDs for notarization (or two adult witnesses), full legal names/addresses, and signatures by both parents.
2) Genetic Testing → Administrative or Court Order
• If parentage is disputed or uncertain, CSEA can arrange DNA testing.
• A ≥99% probability typically results in an Administrative Order of Paternity; courts can also issue paternity orders and address child support within the same case.
What Legal Rights Follow a Paternity Finding?
- Parental rights & responsibilities: ability to seek custody/shared parenting, parenting time/visitation, and access to school/medical records.
- Support & benefits: child support may be set; the child may qualify for insurance or federal benefits through the father.

FAQs (Ohio Fathers)
Does signing the AOP automatically set child support?
Not by itself. Support is set administratively or by court after paternity—often in a separate step.
Can I rescind an AOP?
There are limited time windows and procedures to challenge or rescind an acknowledgment, often by seeking genetic testing and court review. Talk to counsel promptly.
What if the mother was married?
Ohio presumes her husband is the legal father; different procedures apply. Get legal advice before signing anything.
Will I appear on the birth certificate immediately after an AOP?
Yes—once the affidavit is properly executed and filed, the father’s name can be added to the birth certificate.
