Detailed Answer
Under Ohio law a child who is the biological or legally established child of a decedent can inherit from that parent even if the parent’s name does not appear on the child’s birth certificate. Two parts of Ohio law are most important: the Ohio Parentage Act and Ohio’s descent-and-distribution (intestate succession) rules. See the Ohio Parentage Act: https://codes.ohio.gov/ohio-revised-code/chapter-3111, and Ohio descent and distribution: https://codes.ohio.gov/ohio-revised-code/chapter-2105.
If a father’s name is not on a birth certificate, you can establish your legal relationship to him — and thus your inheritance rights — by proving parentage. Ohio provides several common ways to do this:
- Voluntary acknowledgement of parentage (AOP). If the father is alive and willing, he can sign a Voluntary Acknowledgement of Parentage (sometimes called an affidavit of paternity). That form, when executed according to state rules, establishes legal parentage without a court case. If an AOP was signed at birth or later and properly filed, it is strong proof of parentage.
- File a parentage action in court under the Ohio Parentage Act (Chapter 3111). If there is no signed AOP or the father refuses to sign, you can ask the probate court (or juvenile court, depending on local practice) to declare parentage. The court can order genetic testing and then enter a judgment declaring parentage if the evidence supports it. The Parentage Act provides the rules for how parentage is established and how genetic testing is handled. See Chapter 3111: https://codes.ohio.gov/ohio-revised-code/chapter-3111.
- Use genetic (DNA) testing. DNA results are commonly decisive. The court can order testing for the child and the alleged father. If the father is deceased, testing of his known biological relatives (parents, siblings) or preserved biological samples may be possible. The court treats reliable genetic evidence as strong proof of parentage.
- Probate procedures to declare heirship or to add an heir to an estate. If the parent died without a will (intestate) or the estate distribution is at issue, a probate court can determine heirs and approve distribution under Ohio’s descent-and-distribution rules in Chapter 2105. Once parentage is established by AOP or court judgment, the child is treated as an heir and inherits according to those rules. See Chapter 2105: https://codes.ohio.gov/ohio-revised-code/chapter-2105.
- Evidence besides DNA. If DNA is unavailable, courts consider other evidence: contemporaneous acknowledgments (letters, cards), records showing the father treated the child like his own (school or medical records listing him as parent, beneficiary designations, tax returns, social media posts), testimony of family members and friends, proof of financial support, or any official documents where the father claimed paternity. The Parentage Act allows the court to weigh such evidence if genetic proof is not possible.
- When the father is deceased. You can still bring a parentage action against the estate or seek an order in the probate case to declare you an heir. The court will permit DNA testing of relatives or consider other admissible evidence of parentage. Establishing parentage after death allows you to claim inheritance under Chapter 2105.
Practical steps to take now
- Contact the county probate court where the estate is or would be opened and ask how parentage/ heirship disputes are handled locally.
- Search for any voluntary Acknowledgement of Parentage (AOP) filed with the Ohio vital records office or in probate files.
- Collect and preserve evidence: photos, letters, medical or school records, financial records, correspondence, and witness names.
- If the alleged father is alive, ask whether he will sign an AOP or agree to DNA testing. If he is unwilling, be prepared to file a parentage action under Chapter 3111.
- If the alleged father is deceased, ask the probate clerk about filing a petition to establish heirship and how to request genetic testing of surviving relatives or use other evidence.
- Talk to a probate or family law attorney quickly. Courts apply specific procedures and deadlines. An attorney can file the correct petition, arrange court-ordered testing, and present evidence to the judge.
Helpful Hints
- Act promptly. Estates move forward and deadlines for claims or disputes can apply; early action preserves rights.
- If possible, get a voluntary acknowledgement of parentage signed and filed. It is faster and less expensive than a contested court action.
- Genetic testing is powerful. If you can obtain a court-ordered test, it often resolves the issue quickly.
- Even without a birth certificate listing the father, Ohio law recognizes biological children once parentage is legally established. See Ohio Parentage Act (Chapter 3111): https://codes.ohio.gov/ohio-revised-code/chapter-3111.
- Learn the probate court’s local rules. Some courts handle heirship claims in a specific probate docket or require particular forms.
- If you cannot afford a private attorney, search for local legal aid or call your county bar association for a lawyer referral.
Next steps: gather documents and contact the probate court or an attorney who handles parentage or probate matters. An attorney can explain the likely timeline, costs, and the best route — voluntary AOP, court-ordered genetic testing, or a probate heirship action — based on the facts of your situation.
