Ohio Revised Code Title LIII. Real Property § 5309.06

No estate less than a fee simple and no mortgage, lien, or charge of any kind shall be registered unless the fee in possession, remainder, or reversion or other character of fee in and to the land has been registered first or is registered at the same time. If the estate of the applicant is subject to any outstanding lesser estate, including life estates, estates for years, conditional limitations, executory devises or uses, springing or shifting uses, or other future estate, interest, or limitation, whether vested or contingent, is subject to any private easement or other estate or interest of any kind, or is subject to any mortgage, lien, or charge, each lesser estate, private easement, other estate or interest, mortgage, lien, or charge shall be noted on the certificate of title and duplicate of the certificate of title, except taxes not due, leases for less than three years, and restrictive covenants described in division (B) of section 5309.24 of the Revised Code. The title to the estate so registered and certified shall be subject only to the lesser estates, private easements, other estates or interests, mortgages, liens, and charges so noted, except as provided in section 5309.28 of the Revised Code. A perpetual leasehold, for purposes of this chapter and Chapter 5310. of the Revised Code, shall be treated as an estate in fee, and the possible reversion or remainder in fee under the leasehold shall be treated as the lesser estate.

No parcel of land that lies partly in two or more counties shall be registered if one or more of the counties in which the parcel lies have abolished their land registration systems.
