Ohio Rev. Code § 3111.44
After issuing a genetic testing order, the administrative officer may schedule a conference with the mother and the alleged father to provide information. If a conference is scheduled and no other man is presumed to be the father of the child under section 3111.03 of the Revised Code, the administrative officer shall provide the mother and alleged father the opportunity to sign an acknowledgment of paternity affidavit prepared pursuant to section 3111.31 of the Revised Code. If they sign an acknowledgment of paternity, the administrative officer shall cancel the genetic testing order the officer had issued. Regardless of whether a conference is held, if the mother and alleged father do not sign an acknowledgment of paternity affidavit or if an affidavit cannot be notarized or witnessed or filed because another man is presumed under section 3111.03 of the Revised Code to be the father of the child, the child, the mother, and the alleged father shall submit to genetic testing in accordance with the order issued by the administrative officer.
