Oklahoma Eviction Notice: 5-Day Demand for Nonpayment Under § 131

Okla. Stat. tit. 41 § 131(B) lets a landlord "terminate a rental agreement for failure to pay rent when due, if the tenant fails to pay the rent within five (5) days after written notice of landlord's demand for payment"; the demand for past-due rent is itself deemed a demand for possession. For other curable breaches, § 132(B) requires written notice that the agreement terminates no less than 15 days after receipt unless the tenant remedies the breach within 10 days. Breaches threatening imminent, irremediable harm allow immediate termination by filing a forcible entry and detainer (FED) action under § 132(C). After the notice period runs, the landlord brings the FED eviction case in court; self-help lockouts are not permitted.

No specific statutory penalty for serving notice, but a landlord must obtain a court judgment in a forcible entry and detainer action before removing a tenant; self-help eviction (lockouts, utility shutoffs) is unlawful and exposes the landlord to tenant remedies.
