Free Missouri Sublease Agreement
Missouri’s rule has a litigation tail most states do not. RSMo 441.030 requires written assent, and 441.230 lets the landlord join the tenant and every sublessee as defendants in the same action.
Missouri requires the landlord’s written assent before a short-term tenant transfers their interest. What makes the Missouri position distinctive is what happens next: if it reaches a courtroom, the statute is built to put everyone in the same case.

Two years is the line 441.030 draws
The section applies to a tenant “for a term not exceeding two years, or at will, or by sufferance”. A one-year lease and a month-to-month tenancy are inside it. A longer fixed term is not, and for that tenancy your lease clause is what governs.
Watch: Missouri Sublease Agreement explained
Missouri sublease at a glance
Consent statute
RSMo 441.030 — written assent
Terms covered
Not exceeding 2 years, at will, at sufferance
What is required
Written assent of the landlord
If breached
10 days’ notice to vacate (441.040)
441.030 is broader than its title suggests — and 441.040 is narrower
The section is usually cited for the consent rule, but it contains three prohibitions, and the ten-day consequence in 441.040 answers a breach of any of them. A short-term tenant may not transfer their interest without the landlord’s written assent; may not violate any condition of a written lease; and may not commit waste on the premises. So a landlord’s assent to a sublet does not quietly waive the occupancy, pet or parking clauses sitting elsewhere in the same document — a subtenant who breaches one of those puts the tenant in breach of 441.030 through a different door.
How to sublet in Missouri without breaching 441.030
Check whether your term is two years or less, at will, or at sufferance
That is the class of tenancy 441.030 reaches. Outside it, your lease governs.
Ask in writing and keep the written assent
441.030 requires the landlord’s written assent. This is the document that answers a 441.040 notice later, so file it with the sublease rather than in a message thread.
Read the rest of your lease while you are in it
441.030 also prohibits violating any condition of a written lease. An assent to sublet does not waive an occupancy limit, a pet clause or a parking restriction sitting elsewhere in the same document.
Put the sublease in writing — and any assignment, because 432.060 requires it
441.030’s cross-reference points to RSMo 432.060: no lease or interest may be assigned, granted or surrendered unless by deed or note in writing, signed by the party assigning or their agent lawfully authorised by writing, or by operation of law. If what you are really doing is handing over the whole remaining term, that is an assignment.
Tell your subtenant they can be named in the same lawsuit
441.230 permits the landlord to join the lessee and all sublessees as defendants in one action. A subtenant is better off knowing that before they sign.
441.230 and why Missouri subleases end up as one lawsuit
“In case any tenant shall sublet any premises or any part thereof demised or let to him, the landlord shall have the right, in any action provided for by this chapter and chapter 535, to join as party defendants his lessee and all sublessees in the same action.” That converts what would otherwise be two disputes — landlord against tenant, tenant against subtenant — into one proceeding with everyone present. For a landlord it removes the problem of suing the tenant and then discovering someone else is in possession. For a subtenant it means a dispute they had no part in can arrive with their name on it.
What a Missouri sublease agreement should contain
- The property address including unit number, and the county.
- The names of the tenant (as sublessor) and the subtenant.
- The sublease term, ending on or before the end of your own lease.
- The rent, the due date, and the method of payment.
- Any deposit, and the conditions for its return.
- Which utilities the subtenant is responsible for.
- A reference to the landlord’s written assent under 441.030 and the date given.
- An acknowledgment that the subtenant has received the head lease.
- Signatures and dates from both parties.
What goes wrong — and the Missouri rule behind it
- Getting consent by text and calling it written assent. It may well qualify, but the version you can produce months later, with a date and an identifiable sender, is the one that helps you. Ask for it in a form you can file.
- Treating 441.030 as being only about subletting. The same section bars violating any condition of a written lease and committing waste, and 441.040’s ten-day notice answers a breach of any of it.
- Assuming the statute covers your long lease. 441.030 reaches terms not exceeding two years, at will, and at sufferance.
- Not telling the subtenant about 441.230. Being joined as a defendant in the landlord’s action is a foreseeable consequence of signing a Missouri sublease, and it is better disclosed than discovered.
- Calling an assignment a sublease. If you are handing over the entire remaining term and leaving, that is an assignment, and RSMo 432.060 requires it to be by deed or note in writing and signed by the party assigning or their agent authorised in writing, unless it results by operation of law.
Do you need permission to sublet in Missouri?
For most residential tenants, yes — and it has to be written. RSMo 441.030 sets the rule, and it is worth reading in full because it covers more ground than its title suggests.
RSMo 441.030, verbatim
“No tenant for a term not exceeding two years, or at will, or by sufferance, shall assign or transfer his term or interest, or any part thereof, to another without the written assent of the landlord; neither shall he violate any of the conditions of his written lease, nor commit waste upon the leased premises.”
Three prohibitions sit in one sentence: do not transfer your interest without written assent, do not breach the conditions of your written lease, and do not commit waste. They matter together because the consequence section that follows answers a breach of any of them.
Ten days’ notice to vacate, and who can be ousted
RSMo 441.040, with the closing words in full
“If any tenant violates the provisions of section 441.020 or 441.030, the landlord, or person holding under the landlord, after giving ten days’ notice to vacate the premises, shall have a right to reenter the premises and take possession of the premises, or to oust the tenant, subtenant or undertenant of any person on the premises with the permission of the lessee, sublessee or underlessee by the procedure specified by law.”
Those last six words are the whole of it. “Reenter” in a statute carried forward from 1939 does not mean a landlord may take the premises back personally. The section ends by routing the remedy through the procedure specified by law — and Missouri says elsewhere, in terms, what happens to a landlord who skips it.
RSMo 441.233.1
“… a landlord or its agent who removes or excludes a tenant or the tenant’s personal property from the premises without judicial process and court order, or causes such removal or exclusion, or causes the removal of the doors or locks to such premises, shall be deemed guilty of forcible entry and detainer as described in chapter 534.”
Read together: ten days’ notice is the start of a court process, not a countdown to a lockout. A landlord who changes the locks on day eleven has not enforced 441.040 — they have committed the offence 441.233 describes.
The people who can be removed at the end of that process include the subtenant or undertenant — the person who moved in, paid their rent, and may never have been told that assent was required. Their possession depends on a document they did not negotiate. That is the reason a prospective Missouri subtenant should ask to see the landlord’s written assent, and the reason a tenant should be able to show it.
Missouri’s distinctive rule: everyone in one action
This is where Missouri departs from the states with otherwise similar consent statutes.
RSMo 441.230 — If tenant sublet, landlord may join sublessees in same actions
“In case any tenant shall sublet any premises or any part thereof demised or let to him, the landlord shall have the right, in any action provided for by this chapter and chapter 535, to join as party defendants his lessee and all sublessees in the same action.”
Ordinarily a sublease creates two separate relationships and, if things fail, two separate disputes. 441.230 collapses them. The landlord may bring the tenant and every sublessee into a single proceeding rather than suing the tenant, obtaining a judgment, and then discovering that the person actually in the premises was never a party to it.
For a landlord that is an efficiency. For a subtenant it is a risk worth understanding before signing: a dispute about rent you paid on time, arising from an arrangement between two other people, can still arrive with your name on the caption. Disclose it in the sublease. A subtenant who was told is in a very different position from one who was not.
The two-year line, and who falls outside it
441.030 reaches a tenant “for a term not exceeding two years, or at will, or by sufferance”. That covers the ordinary one-year residential lease and the ordinary month-to-month tenancy, which is most renters. It does not cover a longer fixed term.
If your lease runs three years, the statutory written-assent requirement is not what governs you. Your lease clause is. That cuts both ways: a longer-term tenant whose lease is silent is not caught by 441.030, and a longer-term tenant whose lease has a strict no-sublet clause is bound by the clause rather than by anything in chapter 441.
Sublease or assignment — and why Missouri makes you choose in writing
441.030 carries a cross-reference that is easy to miss: assignment of leases to be in writing, 432.060. The distinction it points at is real. A sublease leaves you in the middle, still owing the landlord. An assignment transfers your whole remaining interest and steps someone into your place.
People who want out of a lease often write a document titled “sublease” when what they actually want is an assignment plus a release. Those are different in effect, and only one of them ends your liability — and it only ends it if the landlord agrees to release you, which is a separate act from consenting to the transfer.
You remain liable, and the numbers should reflect it
Nothing in 441.030, 441.040 or 441.230 moves your rent obligation onto your subtenant. You collect from them and you pay the landlord. Set the sublease rent at no less than what you owe, set its due date early enough that a late payment does not make you late, and hold a deposit sized against the damage you would be answering for — because under 441.030 waste on the premises is your problem, whoever caused it.
Read the whole lease before you rely on an assent
Because 441.030 also prohibits violating “any of the conditions of his written lease”, a landlord’s written assent to a sublet does not quietly waive everything else in the document. Occupancy limits, pet restrictions, parking allocations and guest rules all continue to apply, and a subtenant who breaches one puts the tenant in breach of 441.030 through a different door. Give the subtenant the lease, and point at the clauses that will affect how they live there.
Where the sublease question sits in Missouri law
A sublease rarely arrives on its own. Most people reach one because something else has changed — a job in another city, a relationship ending, a lease with months left on it — so it is worth knowing what the alternatives cost before you commit to this one. Our guide to breaking a lease in Missouri sets out the early-exit routes and what each of them exposes you to, and in some situations ending the tenancy outright is cleaner than running a sublease you will have to manage from a distance.
The two disputes that actually follow a sublease are about money and about possession. On money, the deposit is where most of it happens, and the rules that govern what a landlord may take and when it has to come back are set out in Missouri security deposit laws — worth reading before you decide what to hold from your subtenant, and before you assume you know what the owner may hold from you.
On possession, the notices and timelines that apply if things go wrong are covered in Missouri eviction notice laws. You are the landlord in the sublease relationship, so those rules are as likely to be yours to use as to be used against you.
Bottom line
RSMo 441.030 requires the landlord’s written assent for a term of two years or less, at will, or at sufferance, and also bars breaching any condition of a written lease. A breach opens 441.040 — ten days’ notice to vacate, and then the remedy the section itself routes “by the procedure specified by law”: a court process, not a lockout. RSMo 441.233 makes removing a tenant, or the doors or locks, without judicial process and court order forcible entry and detainer. The Missouri feature to plan around is 441.230: the landlord may join the lessee and every sublessee as defendants in one action, so tell your subtenant that before they sign.
Frequently Asked Questions
Do I need my landlord’s written permission to sublet in Missouri?
If your tenancy is for a term not exceeding two years, at will, or at sufferance, then yes. RSMo 441.030 requires the written assent of the landlord before the tenant assigns or transfers their term or interest, or any part of it.
What happens if I sublet without written assent in Missouri?
RSMo 441.040 lets the landlord, after ten days’ notice to vacate, reenter and take possession or oust the tenant, subtenant or undertenant — but the section ends “by the procedure specified by law”. That means a court process. Under RSMo 441.233.1 a landlord who removes or excludes a tenant, or removes the doors or locks, without judicial process and court order is deemed guilty of forcible entry and detainer under chapter 534.
Can my Missouri landlord change the locks after the ten days?
No. RSMo 441.233.1 makes removal or exclusion without judicial process and court order, or removing the doors or locks, forcible entry and detainer as described in chapter 534. The ten days begins a court process; it is not a countdown to a lockout.
Can my landlord sue me and my subtenant at the same time?
Yes. RSMo 441.230 gives the landlord the right, in any action provided for by chapter 441 and chapter 535, to join the lessee and all sublessees as party defendants in the same action.
Does the Missouri consent rule apply to every lease?
No. RSMo 441.030 reaches tenancies for a term not exceeding two years, at will, or at sufferance. A longer fixed term falls outside the section and is governed by the lease.
Is a text message enough for “written assent”?
The statute says written assent without prescribing a form. The practical test is whether you can produce it later with a date and an identifiable sender, so ask for it in a form you can file alongside the sublease.
Does subletting end my responsibility for the rent in Missouri?
No. You remain liable to the landlord. RSMo 441.030 also makes you answerable for breaches of your lease conditions and for waste on the premises.
What is the difference between subletting and assigning in Missouri?
A sublease leaves you in the middle, still owing the landlord. An assignment transfers your entire remaining interest. RSMo 441.030 cross-references 432.060, under which an assignment must be by deed or note in writing and signed by the party assigning or their agent authorised in writing, unless it results by operation of law.
Can my subtenant be evicted for my breach?
RSMo 441.040 names the tenant, subtenant or undertenant among those who may be ousted. A prospective subtenant should ask to see the landlord’s written assent before moving in.
