Ohio Rev. Code § 711.24
Any person owning, either jointly or severally, and either in his own right or in trust, and having the legal title to any land laid out in town lots, not within the limits or subject to the control of a municipal corporation, may change such lots and the streets and alleys bounding them by making, acknowledging, and having recorded, as provided in sections 711.01 to 711.38, inclusive, of the Revised Code, a new plat of such land, and having the proper transfers made in the office of the county auditor. No such change shall be made if it injuriously affects any lots on the streets or alleys, or within the plat so changed, unless all the owners of the lots so affected are parties joining in making the change, or such owners give their consent in writing on the new plat, which is recorded therewith. Any change of a town plat made under this section shall have the same effect as if made by the judgment of a court having jurisdiction thereof.
