You must use the courts to evict a Tenant in Missouri. You do this by filing an Unlawful Detainer action in the Associate Circuit Court of the county where the property is located. There are generally two issues in an eviction case: (1) possession of the property and (2) money damages.

Once proper notice has been served on the Tenant, you can file an Unlawful Detainer action (the "Petition"). Missouri does not require specific language in the petition, but it must state that you are entitled to possession and that the Tenant is wrongfully holding the property. Include a copy of your Affidavit of Service.

The summons notifies the Tenant of the Unlawful Detainer action. When completing the summons, include "Unknown Occupants" as a defendant. This ensures the court order covers all persons in the property, not just named defendants. The summons must be accurately completed and filed with the court, and is typically served by the sheriff.

Does it cost to sue if I'm representing myself?

Yes. Filing fees, sheriff's fees, and other costs still apply. Your lease should allow you to recover these from the Tenant. If not, get a better lease.

Are there other resources to help?

The Missouri Courts website (courts.mo.gov) has forms and guidance for self-represented litigants. Your local Associate Circuit Court clerk can also point you to the right forms for your county.

What happens after I win?

If you obtain a judgment for possession, you must wait for the sheriff to enforce the order. You cannot remove the Tenant yourself — see our Self-Help Evictions guide.
