Ohio Revised Code Title XXXI. Domestic Relations Children § 3111.821

If a request is made pursuant to section 3111.78 of the Revised Code for an administrative support order and the issue of the existence or nonexistence of a parent and child relationship is raised, the administrative officer shall treat the request as a request made pursuant to section 3111.38 of the Revised Code and determine the issue in accordance with that section. If the request made under section 3111.78 of the Revised Code is made based on an acknowledgment of paternity that has not become final, the administrative officer shall promptly notify the office of child support in the department of job and family services when the officer issues an order determining the existence or nonexistence of a parent and child relationship with respect to the child who is the subject of the acknowledgment of paternity. On receipt of the notice by the office, the acknowledgment of paternity shall be considered rescinded.

If the parties do not raise the issue of the existence or nonexistence of a parent and child relationship pursuant to the request made under section 3111.78 of the Revised Code and an administrative order is issued pursuant to section 3111.81 of the Revised Code prior to the date the acknowledgment of paternity becomes final, the acknowledgment shall be considered final as of the date of the issuance of the order. An administrative order issued pursuant to section 3111.81 of the Revised Code shall not affect an acknowledgment that becomes final prior to the issuance of the order.
