Okla. Stat. tit. 41, § 41-119: Conveyance of property - Attornment of tenant

A. A conveyance of real estate, or of any interest therein, by

a landlord shall be valid without the attornment of the tenant, but

the payment of rent by the tenant to the grantor at any time before

written notice of the conveyance is given to the tenant shall be

good against the grantee.

B. The attornment of a tenant to a stranger shall be void, and

shall not affect the possession of the landlord unless it is made

with the consent of the landlord, or pursuant to a judgment at law,

or the order or decree of a court.

C. Unless otherwise agreed and except as otherwise provided in

this act, upon termination of the owner's interest in the dwelling

unit including, but not limited to, terminations of interest by

sale, assignment, death, bankruptcy, appointment of a receiver or

otherwise, the owner is relieved of all liability under the rental

agreement and of all obligations under this act as to events

occurring subsequent to written notice to the resident of the

termination of the owner's interest. The successor in interest to

the owner shall be liable for all obligations under the rental

agreement or under this act. Upon receipt by a resident of written

notice of the termination of the owner's interest in the dwelling

unit, a resident shall pay all future rental payments, when due, to

the successor in interest to the owner.

D. Unless otherwise agreed and except as otherwise provided in

this act, a manager of premises that includes a dwelling unit is

relieved of liability under a rental agreement and this act as to

events occurring after written notice to the tenant of the

termination of his management.
