Ohio Rev. Code § 711.20
The proceedings for vacating or altering a plat under sections 711.17 to 711.19 of the Revised Code, shall be recorded by the clerk of the court of common pleas in the records of the court of common pleas. A copy of such record shall be made and certified, under the seal of the court, by the clerk thereof, and shall be deposited, by the parties applying for such vacation or alteration, within thirty days after such certification with the county recorder, who shall record it. At the term at which notice is given of such application, or at any subsequent term during the pendency of the application, any person feeling interested in the proceedings, upon motion, may be made a party defendant to the application, in which case, upon final hearing, the party succeeding shall have judgment against the other for the costs of the proceedings, and execution may issue therefor as in other cases.
