Ohio Rev. Code Ann. § 5311.10

In any deed, mortgage, lease, or other instrument of conveyance or encumbrance of, or by which a lien is created upon any interest or estate in any unit of condominium property, it is sufficient to describe the unit by setting forth the name of the condominium property, the number or other designation of the unit, and the numbers of the volumes and initial pages of the records of the declaration and drawings of the condominium property. This section does not require reference by volume and page to amendments to the declaration or the drawings of the condominium property that accompany an amendment, and the omission of any reference to amendments does not affect the validity of any deed, mortgage, lease, or other instrument referred to in this section.
