§41-111.
   
   A. Except as otherwise provided in the Oklahoma Residential Landlord
   and Tenant Act, when the tenancy is month-to-month or tenancy at will,
   the landlord or tenant may terminate the tenancy provided the landlord
   or tenant gives a written notice to the other at least thirty (30)
   days before the date upon which the termination is to become
   effective. The thirty-day period to terminate shall begin to run from
   the date notice to terminate is served as provided in subsection E of
   this section.
   
   B. Except as otherwise provided in the Oklahoma Residential Landlord
   and Tenant Act, when the tenancy is less than month-to-month, the
   landlord or tenant may terminate the tenancy provided the landlord or
   tenant gives to the other a written notice served as provided in
   subsection E of this section at least seven (7) days before the date
   upon which the termination is to become effective.
   
   C. Unless earlier terminated under the provisions of the Oklahoma
   Residential Landlord and Tenant Act or unless otherwise agreed upon, a
   tenancy for a definite term expires on the ending date thereof without
   notice.
   
   D. If the tenant remains in possession without the landlord's consent
   after the expiration of the term of the rental agreement or its
   termination under the Oklahoma Residential Landlord and Tenant Act,
   the landlord may immediately bring an action for possession and
   damages. If the tenant's holdover is willful and not in good faith the
   landlord may also recover an amount not more than twice the average
   monthly rental, computed and prorated on a daily basis, for each month
   or portion thereof that said tenant remains in possession. If the
   landlord consents to the tenant's continued occupancy, a
   month-to-month tenancy is thus created, unless the parties otherwise
   agree.
   
   E. The written notice, required by the Oklahoma Residential Landlord
   and Tenant Act, to terminate any tenancy shall be served on the tenant
   or landlord personally unless otherwise specified by law. If the
   tenant cannot be located, service shall be made by delivering the
   notice to any family member of such tenant over the age of twelve (12)
   years residing with the tenant. If service cannot be made on the
   tenant personally or on such family member, notice shall be posted at
   a conspicuous place on the dwelling unit of the tenant. If the notice
   is posted, a copy of such notice shall be mailed to the tenant by
   certified mail. If service cannot be made on the landlord personally,
   the notice shall be mailed to the landlord by certified mail. For the
   purpose of this subsection, the word "landlord" shall mean any person
   authorized to receive service of process and notice pursuant to
   Section 116 of this title.
