Okla. Stat. tit. 27, § 27-14: Buildings, structures and other improvements - Taking with

real property.

A. Where any interest in real property is acquired, an equal

interest shall be acquired in all buildings, structures or other

improvements located upon the real property which are required, by

the head of the acquiring entity, to be removed from such real

property or which he determines to be adversely affected by the use

to which such real property will be put.

B. For the purpose of determining the just compensation to be

paid for any building, structure or other improvement required to be

acquired as by subsection A of this section, such building,

structure or other improvement shall be deemed to be a part of the

real property to be acquired notwithstanding the right or obligation

of a tenant, as against the owner of any other interest in the real

property, to remove such building, structure or improvement at the

expiration of his term, and the fair market value which such

building, structure or improvement contributes to the fair market

value of the real property to be acquired or the fair market value

of such building, structure or improvement for removal from the real

property, whichever is the greater, shall be paid to the tenant

therefor.

C. Payment under this section shall not result in duplication

of any payments otherwise authorized by law. No such payment shall

be made unless the owner of the land involved disclaims all interest

in the improvements of the tenant. In consideration for any such

payment, the tenant shall assign, transfer and release to the

acquiring entity all his right, title and interest in and to such

improvements. Nothing in this section shall be construed to deprive

the tenant of any rights to reject payment under this section and to

obtain payment for such property interests in accordance with

applicable law other than this section.
