Eviction Laws in Missouri
Non-payment of rent eviction in Missouri
When a tenant falls behind on rent in Missouri, the landlord must first serve a 0-day pay-or-quit notice. This gives the tenant 0 days to either pay the full amount owed or vacate. If the tenant does neither, the landlord can file an eviction lawsuit — called an unlawful detainer or summary possession action — in Missouri court.
A court order is required before any lockout. The landlord cannot change the locks, shut off utilities, or remove the tenant's belongings before winning a judgment.

Missouri provides no statutory cure period for lease violations — the tenant may be required to vacate without the opportunity to fix the issue, depending on the nature of the violation.
Terminating month-to-month tenancy in Missouri

What counts as an illegal eviction in Missouri?
In Missouri, a landlord who attempts to evict a tenant without following the legal process commits an illegal (self-help) eviction. This includes:
- Changing the locks without a court order
- Removing doors, windows, or the tenant's belongings
- Shutting off utilities (electricity, water, heat)
- Harassment designed to pressure the tenant to leave
Self-help evictions are prohibited in all 50 states and DC. Tenants who experience an illegal lockout can typically seek emergency relief from a court and may be entitled to damages.
