Ohio Rev. Code § 503.04: Notice of hearing - record of boundaries.

Before action is taken on an application for partition, alteration, change, or laying off of the boundaries of a township by the board of county commissioners, at least thirty days' notice of the time for the hearing on such application or petition shall be given by advertisement, at three public places within the bounds of the territory proposed to be partitioned, altered, changed, or laid off. The board shall cause the boundaries of such township, so changed or altered, or new township laid off, to be recorded in a book to be kept for that purpose, and shall give each new township, so laid off, an appropriate name. No two townships in any county shall be incorporated by the same name.
