Ohio Revised Code Title XXXI. Domestic Relations Children § 3111.08

(A) An action brought pursuant to sections 3111.01 to 3111.18 of the Revised Code to declare the existence or nonexistence of the father and child relationship is a civil action and shall be governed by the Rules of Civil Procedure unless a different procedure is specifically provided by those sections.

(B) If an action is brought against a person to declare the existence or nonexistence of the father and child relationship between that person and a child and the person in his answer admits the existence or nonexistence of the father and child relationship as alleged in the action, the court shall enter judgment in accordance with section 3111.13 of the Revised Code. If the person against whom the action is brought fails to plead or otherwise defend against the action, the opposing party may make an oral or written motion for default judgment pursuant to the Rules of Civil Procedure. The court shall render a judgment by default against the person after hearing satisfactory evidence of the truth of the statements in the complaint.
