Missouri Execution in Unlawful Detained for Possession of Premises is a legal process for landlords to use to regain possession of their rental property from tenants who have failed to comply with the terms of the lease. This process can be used if a tenant fails to pay rent, violates the lease in some way, or fails to vacate the premises after the lease has expired. There are two types of Missouri Execution in Unlawful Detained for Possession of Premises: summary and regular. The summary process is a quicker way to regain possession, while the regular process is used if the landlord wants to pursue a money judgment against the tenant. In either case, the landlord must first file a petition with the court, serve the tenant with notice, and wait for the court to issue an eviction order. If the tenant fails to comply with the eviction order, the landlord can then execute the order by having a sheriff or constable remove the tenant from the property.
