Ohio Rev. Code § 3311.18
Subject to the consent of the board of education of each school district whose territory is proposed to be included within a joint vocational school district, the initiating unit may create a joint vocational school district within the county or within an area comprised of two or more adjoining counties, composed of the territory of all the school districts whose boards of education have approved the formation of the joint vocational school district. The effective date for the establishment of such district shall be designated by the initiating unit. The boards of education of the school districts participating in the establishment of a joint vocational school district may participate on a proportional basis in meeting the administrative, clerical, and other expenses necessary to the establishment and operation of a joint vocational school district until funds are otherwise provided. A school district shall not lose its separate identity or legal existence by reason of becoming a part of a joint vocational school district. Expenditures made by a school district participating in the establishment of a joint vocational school district for meeting the administrative, clerical, and other expenses necessary to the establishment and operation of a joint vocational school district until such time as the joint vocational school district commences to receive revenues as provided by law are hereby ratified and declared to have been lawfully made, the same as if such contributions had been lawful at the time they were made.
