A Missouri eviction notice takes one of three forms depending on why the landlord wants the tenant out. For unpaid rent, state law requires no written notice and no waiting period before filing suit, though the landlord must have demanded the rent. For serious criminal activity on the property, the landlord must give a written ten-day notice to vacate. For ending a month-to-month tenancy without cause, either side must give written notice at least one month before the next rent-paying date.
Nonpayment of Rent
Missouri does not require a written “pay or quit” notice before a landlord sues for unpaid rent. RSMo 535.010 lets a landlord recover possession whenever the tenant fails to pay rent on time, without imposing any waiting period.1Missouri Revisor of Statutes. Missouri Code 535.010 – If Rent Be Not Paid as Agreed, Landlord May Recover Possession, How RSMo 535.020 makes the point explicit: the written notice referenced in Section 441.060 “is not required prior to filing” a rent-and-possession case.2Missouri Revisor of Statutes. Missouri Code 535.020 – Procedure to Recover Possession
There is still a requirement, though. RSMo 535.040 tells the court not to enter judgment unless it finds that “the rent which is due has been demanded of the tenant” and payment was not made.3Missouri Revisor of Statutes. Missouri Code 535.040 – Upon Return of Summons, Cause to Be Heard A demand can be oral, but a written demand creates a record that holds up in court. Many landlords send a dated demand letter with the exact amount owed even though the statute does not require one, simply because it is easier to prove later.
Ten-Day Notice for Criminal Lease Violations
Certain prohibited activities on the rental property trigger a ten-day written notice to vacate before the landlord can file for possession. RSMo 441.040 ties this notice to the violations listed in RSMo 441.020 and 441.030.4Missouri Revisor of Statutes. Missouri Code 441.040 – Landlord May Take Possession, When
The activities are specific: operating a gambling operation, running a brothel, or allowing illegal drug possession, sale, or distribution on the premises.5Missouri Revisor of Statutes. Missouri Code 441.020 These are not ordinary lease violations like an unauthorized pet or noise complaints. When any of these occur, the lease becomes void by operation of law, and the landlord can proceed once the ten days pass.
This is a notice to vacate, not a notice to cure. The tenant does not get the option to stop the activity and stay. Even with the lease voided, the landlord still has to go through the courts rather than removing the tenant directly.
One-Month Notice to End a Month-to-Month Tenancy
Ending a month-to-month arrangement requires the most lead time. RSMo 441.060 allows either the landlord or the tenant to terminate a month-to-month tenancy by giving written notice at least one month before the next rent-paying date.6Missouri Revisor of Statutes. Missouri Code 441.060 – Tenancy at Will, Sufferance, Month to Month, How Terminated The same rule covers tenancies at will, tenancies by sufferance, and any tenancy for less than a year.
The timing detail matters. The termination date must land on a rent-paying date, and the tenant needs a full month between receiving the notice and that date. If rent is due on the first and the notice goes out on January 15, the earliest the tenancy ends is March 1, not February 15. Oral agreements without a written lease automatically create month-to-month tenancies under Missouri law, so this notice applies even when nothing was signed.
One exception: when a tenant owns a mobile home and rents the lot underneath it, the landlord must give at least sixty days’ notice so the tenant has time to arrange to move the home.8Missouri Revisor of Statutes. Missouri Code 441.060 – Tenancy at Will, Sufferance, Month to Month, How Terminated
Expedited Eviction for Drug Activity
Missouri has a separate fast-track process for drug-related crimes on or near the property. Under RSMo 441.740, a court can order immediate eviction if it finds that drug-related criminal activity occurred on the leased property, that the property was used to further drug activity, or that a tenant, household member, or guest engaged in drug-related crimes on or near the premises.7Missouri Revisor of Statutes. Missouri Code 441.740 – Immediate Eviction Ordered, When
After a court order under this section, the tenant has just twenty-four hours to vacate.9Missouri Revisor of Statutes. Missouri Code 441.770 The court can also order the removal and banning of any specific person who engaged in the criminal activity, barring them from returning to any part of the property. A court may stay the eviction only if the tenant proves by clear and convincing evidence that immediate removal would pose a serious danger outweighing the safety of the surrounding community.
What the Notice Should Say
Missouri’s statutes do not prescribe a form for eviction notices. The law requires written notice for the situations above without mandating specific content. A bare-bones notice is still a practical mistake. Judges expect clarity, and a vague notice can create problems if the case is contested.
A well-drafted notice includes:
- Full names of all adult tenants on the lease, so there is no argument about who was notified.
- The complete property address, including unit or apartment number.
- The reason for the notice. For nonpayment, the exact dollar amount owed and the period it covers.
- The deadline to comply or vacate, calculated from the applicable notice period.
- The date of the notice and the landlord’s signature.
For a nonpayment demand, documenting the exact amount matters because a tenant can still stop the eviction by paying the full balance plus court costs before the judge rules. A demand that was unclear about the amount gives the tenant more room to argue they did not know what was owed.
Delivering the Notice
Missouri’s statutes are more specific about how a court summons is served than about how a pre-filing notice is delivered. The safest approach for the notice itself is personal delivery: hand the document directly to the tenant and record the date, time, and location. If the tenant is not home, leaving the notice with another adult at the residence and mailing a copy provides a reasonable paper trail.
Posting on the front door is a common backup. A landlord who posts should take a timestamped photograph and mail an additional copy to the tenant’s address. If the case reaches court, the landlord has to show the tenant received or had a reasonable opportunity to receive the notice.
Delivery of a pre-filing notice is not the same as service of the lawsuit. Once a case is actually filed, RSMo 535.030 governs how the summons must be served, allowing personal service or, when the tenant cannot be found, posting on the dwelling in a conspicuous place and mailing a copy to the last known address at least ten days before the court date.10Missouri Revisor of Statutes. Missouri Code 535.030 – Service of Summons, Court Date Included in Summons Those are court-mandated methods for legal process, not for the informal notice that precedes filing.
The Notice Does Not Let a Landlord Skip the Courts
A properly served notice is a step toward filing suit, not a substitute for one. RSMo 441.233 makes it a violation for a landlord to remove or exclude a tenant without a court order, to take off doors, to change locks, or to cut off electricity, gas, water, or sewer service.11Missouri Revisor of Statutes. Missouri Code 441.233 – Landlords Unlawful Removal or Exclusion of Tenant, Liability The only exception is action taken for genuine health or safety reasons. A landlord who tries to enforce the notice by self-help can end up as the defendant in a forcible entry and detainer case.
Servicemember Tenants
Active-duty military members and their dependents have additional protection under the federal Servicemembers Civil Relief Act. A landlord cannot evict a servicemember or their dependents without a court order when the property is a primary residence and the monthly rent does not exceed $10,542.60, the 2026 threshold adjusted annually for inflation.12Federal Register. Notice of Publication of Housing Price Inflation Adjustment If military service materially affects the servicemember’s ability to pay rent, the court may stay the case for up to ninety days or adjust the lease obligations. SCRA violations carry serious federal consequences, so a landlord facing this situation should consult an attorney before proceeding.
