Missouri subletting rules for landlords: one lawsuit can name the tenant and every sublessee

What does section 441.230 do?

In case any tenant sublets any premises or any part of them demised or let to the tenant, the landlord has the right, in any action provided for by chapter 441 and chapter 535, to join as party defendants the lessee and all sublessees in the same action. The page shows the section as effective August 28, 1939, from the 1939 revision. Chapter 441 covers landlord and tenant, and chapter 535 covers the courts that hear rent and possession cases.

For a landlord, the practical value is simple: one case, not several. If the unit has a tenant and two subtenants, you do not have to sue each separately to recover possession or rent.

What does it not do?

It does not say whether a tenant may sublet, whether the landlord must consent, how quickly the landlord must answer, or what reasons for refusal are acceptable. The section assumes subletting can happen and tells you how to reach everyone involved. Whether a sublet is allowed depends on the lease.

Example a made-up landlord in Kansas City, Missouri has a tenant who sublets two rooms. When the rent stops, the landlord files one action and names the tenant and both sublessees. The statute allows that joinder.

What belongs in a Missouri lease?

• Whether subletting or assignment is allowed, and whether your written consent is needed.
• That any subtenant is bound by the lease.
• That the original tenant stays responsible for rent and damage.
• How the tenant must tell you about any subtenant, and by what date.

Which records help if you must go to court?

Because you may name every sublessee, you need to know who they are. Keep each subtenant's full name, the date they moved in and the rent they pay. If a subtenant was approved, keep the written approval. If one was not, keep the evidence that you did not agree: your notice, the tenant's reply and any rent you refused. Accepting rent from a subtenant can complicate a claim that you never agreed, so be deliberate about what you accept.

Why records matter more here

Because the statute is about who can be named in a case, your records decide how useful it is. Keep the tenant's disclosures about any subtenant, the dates they arrived and any written consent or refusal you sent. Note who pays rent and by what method. If you intend to treat a subtenancy as unauthorized, act promptly and consistently: send a written notice, decline rent from the unapproved occupant and offer an application. If you decide to approve, do it in writing and restate that the lease terms continue. When the time comes to file, a clean list of names and dates makes the joinder simple. Check which court hears your case and what that court requires for naming additional defendants before you file. If a subtenant pays you directly, note it in the file so the amounts are clear.

How DoorKeeping fits in Missouri

DoorKeeping keeps a Missouri tenant's sublet or assignment request in the unit's message thread with the date it arrived, the proposed occupant's details and your reply. Names and move-in dates for every occupant sit on the unit record, which is the list you would name in one action. This is general information, not legal advice. Check the current statute and your lease before you act.
