Missouri Notice to Vacate: 2026 Landlord Rules & Two-Action Eviction

Missouri splits landlord possessory actions into two tracks. A rent and possession action under RSMo Chapter 535 is for nonpayment of rent; under § 535.020 the landlord must have demanded the rent before filing a verified statement, and a tenant can generally defeat possession by paying all rent and costs into court before judgment. An unlawful detainer action under RSMo Chapter 534 is for a tenant who holds over after the tenancy is terminated, after foreclosure, or after lease-end or a lease violation, and requires a written demand for possession. The two pathways have different notice triggers, so a landlord should identify the correct action before serving notice.

It depends on the ground. For nonpayment, Chapter 535 sets no statutory cure-notice day count and no statutory grace period; the statute requires a demand for the rent, not an N-day pay-or-quit notice, though a tenant can often pay rent and costs into court before judgment. For ordinary lease-covenant violations, Missouri statute does not prescribe a general cure period, so whether the tenant may cure depends on the written lease. For drug-related criminal activity and the other conduct described in Mo. Rev. Stat. §§ 441.020 and 441.030, § 441.040 authorizes the landlord, after a ten days' notice to vacate, to reenter and take possession or oust the tenant by the statutory procedure, with no cure right stated.

Two layers can apply. The federal Servicemembers Civil Relief Act (50 U.S.C. § 3955) permits an active-duty servicemember-lessee to terminate a residential lease on entry into military service or on qualifying permanent-change-of-station or deployment orders, and adds eviction protections. Missouri also has a statutory early lease-termination right for servicemembers ordered to active duty or a permanent change of station. A landlord who receives a servicemember termination notice should verify the orders before proceeding with a notice to vacate or a possessory action on the same tenancy. Confirm the controlling federal and Missouri provisions against the official sources before relying on specific terms.

A defective notice can delay or defeat your possessory action. Mo. Rev. Stat. § 441.060 requires the termination notice to be in writing, so an oral notice does not satisfy the statute. For a month-to-month termination the notice must state that the tenancy terminates on a periodic rent-paying date not less than one month after receipt. For a mobile-home-lot tenancy the notice must set termination not sooner than sixty days from the date the rent payment next becomes due, and for the § 441.040 drug or criminal-activity ground the notice must give ten days to vacate. If the wrong action is filed or the demand or notice the statute requires was not made, the court can dismiss and force the landlord to start over.

Missouri does not have a broad statewide anti-retaliation statute the way some states do. What Missouri Chapter 441 does provide is § 441.233, which prohibits self-help eviction. A landlord or agent who removes or excludes a tenant or the tenant's property without judicial process and a court order, or who removes the doors or locks, is deemed guilty of forcible entry and detainer under Chapter 534. The same section bars a landlord from willfully interrupting essential services such as electric, gas, water, or sewer, except where the action is taken for health or safety reasons. Because Missouri has no general retaliation statute, a tenant's protections rest on these self-help and essential-services prohibitions rather than a broad retaliatory-eviction bar.

Local rules can vary by city and county and should be checked at the current city or county source before you rely on them. Missouri broadly preempts local rent control, and no Missouri municipality is known to operate a binding just-cause-only eviction ordinance overriding the state default. Filing fees and service fees are set at the county level and differ across counties, so confirm the current schedule with the circuit clerk in the county where the property is located. Any St. Louis or Kansas City tenant-protection ordinance should be verified at the city source for current effect, because such ordinances can be subject to state preemption.

Not automatically. Missouri does not have a statewide statute that automatically seals rent and possession or unlawful detainer records. Case records are generally public on the Missouri Courts Case.net portal. Sealing or expungement is available only through general motion practice, not as an automatic result of dismissal or settlement, so landlords reviewing applicant rental history may encounter publicly available case records.
