Adult Declaration of Paternity

Establishing paternity for a person over the age of 23

When a child is over the age of 23 and the birth certificate does not designate a father, a Joint Declaration of Paternity must be filed in the county where the father lives, if the father is a resident of the State of Ohio. If the father is not a resident of the State of Ohio, the Joint Declaration may be filed in any county in Ohio as long as the child was born in Ohio.

Forms may be obtained from a Probate Court clerk, or by downloading the forms at the Summit County Probate Court website. Fill out the Joint Declaration of Paternity, Supporting Affidavit and Order Affirming Joint Declaration.

Attach to the Joint Declaration the following two items:

  • Certified copy of the original birth certificate. (Note: The child’s birth certificate must show that no one has been designated as the father.)
  • A copy of the genetic test showing that the applicant is the father.


The Joint Declaration must be signed by both the mother and the father unless the mother is deceased or has been declared incompetent. The child and both parents must appear before a magistrate or the judge. Once all documents are reviewed, and the hearing is completed, the applicant will receive an Order to change the birth certificate.

Filing Fee:

  • The filing fee is $35.00.
  • You may pay the fee in cash, money order, personal check, or credit card.
  • If you use a credit card, a 3% charge will be added.


You must send a certified copy of the Order to the Bureau of Vital Statistics to have the birth records corrected.

Send your certified copy of the Order and $21.50 for a new birth certificate to:

Bureau of Vital Statistics
Ohio Department of Health

246 North High Street
P.O. Box 15098
Columbus, Ohio 43215-0098

You should receive the new birth certificate in 8 to 12 weeks.
