Frequently Asked Questions

Adult Paternity Declaration (RC 2105.25)

What is a Declaration of Paternity?

If the birth certificate for an adult child born in Ohio who is at least 23 years of age does not list a father, the man alleging to be the father, the child’s mother, if living, and the adult child may appear together in the Probate Court and file a Joint Declaration requesting that the man be declared to be the father of the child. This procedure is also referred to as a declaration of fatherhood of an adult child.

What if the Child's Mother is Deceased or Incompetent?

If the mother of the child is incompetent or not living only the adult child’s father and the adult child must appear. Satisfactory proof of the death or incompetence must be provided to the Court and the name and address of the guardian, if any, for the mother must be provided.

What documents must be provided with the Declaration of Paternity?

At the time the Joint Declaration is filed all of the following documents also must be filed: (a) the results of the genetic testing as defined in RC 3111.09 showing the man to be the child’s father with a probability at least 99.0%, (b) a current government issued photo identification for each of the parties, (c) a certified copy of the adult child’s “birth copy” birth certificate, and (d) if applicable, proof of the death or incompetence of the mother of the child.

In What County is the Declaration Filed?

The Joint Declaration of Paternity may be filed in the probate court of the county where the father resides. If the father does not reside in Ohio, the filing may be made in any county of the state.

What Standard does thee Court Apply when Determining Whether to Approve the Joint Declaration?

Only if the Court determines that the request is in the best interest of both the requesting father and the adult child may the Court issue the requested order.

What is the Meaning of the Order?

The Court’s approval of the request means that the child is considered to be a child of the father as if born to him in wedlock, except that the declaration does not result in child support to the mother from the father for the time the child was a minor.
The Court’s order will also direct that the child’s birth certificate be changed to designate the father. In order to obtain the new birth certificate one of the applicants will need to send a certified copy of the court order (with the fee required by the Ohio Department of Health) to:
