Oklahoma Lease Termination: 30 Days' Notice on Month-to-Month Under § 111

Okla. Stat. tit. 41 § 111(A) provides that for a month-to-month tenancy 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," with the 30 days running from service. Section 111(B) sets a 7-day notice for tenancies shorter than month-to-month. Under § 111(C), a definite-term tenancy expires on its ending date without notice unless otherwise agreed. If a tenant holds over, § 111(D) lets the landlord sue for possession, and a willful, bad-faith holdover can owe up to twice the average daily rent. Section 111(E) sets the service rules.

No specific statutory penalty for giving notice, but a willful, bad-faith holdover after termination exposes the tenant under § 111(D) to liability of up to twice the average monthly rent, prorated daily, for each month of wrongful possession.
