In Ohio, paternity can be established in three ways:
Acknowledgment of Paternity Affidavit: By signing this affidavit, both parents agree that a man is the biological father of a child and choose to make him the legal father of the child. To see if the Acknowledgment of Paternity Affidavit is appropriate for your situation, please utilize the link below.
Administrative Order of Paternity: For unmarried parents that have not established paternity through another method and wish to get genetic testing, the Child Support Enforcement Agency can conduct the testing and issue an order of paternity if the man is indeed the biological father of the child. If the mother lives in Ohio, please contact the Child Support Enforcement Agency (CSEA) in the mother's county of residence. If the mother lives outside of Ohio, you may contact the CSEA in the father's county of residence.
Court Order of Paternity: Paternity may be established through Juvenile Court and sometimes through Domestic Relations Court (as part of a divorce.)
