Missouri: Residential Lease Execution Formalities

Requirements one by one

Writing threshold

Missouri uses more than one writing rule. Mo. Rev. Stat. § 432.010 bars an
action on a lease longer than one year, or another agreement not performable
within one year after making, unless a writing or memorandum is signed by the
party against whom enforcement is sought or a lawfully authorized person.

For an ordinary house or other building, § 441.060.3 reaches shorter terms too.
If the agreement is not written and signed by the parties or their agents, the
statute treats the occupancy as month-to-month. The general land-lease rule in
§ 432.050 likewise gives a parol lease only the force of an estate at will.

Required signatures and authority

The signature depends on the consequence at issue. Section 432.010 accepts the
signature of the party to be charged or a lawfully authorized person for an
action. Section 441.060.3 requires the written residential-building agreement
to be signed by the parties or their agents to avoid month-to-month treatment.

Section 432.050 expressly describes agents as lawfully authorized in writing.
Mo. Rev. Stat. § 432.060 uses the same written-authority rule when an agent signs a lease
assignment, grant, or surrender.

Witness, acknowledgment, and notary

The statutes state no witness, acknowledgment, or notary requirement merely to
bind the original landlord and tenant under the writing rules above. Recording
is different. Mo. Rev. Stat. § 442.130 requires a conveyance of an estate or
interest in land to be subscribed and acknowledged or proved and certified;
§ 442.150 lists an in-state notary public among the authorized officers.

Electronic execution

Missouri's Uniform Electronic Transactions Act applies to an ordinary lease
because § 432.210's exclusions do not include it. Under § 432.220, each party
must agree to transact electronically, with consent determined from the context,
surrounding circumstances, and conduct.

Mo. Rev. Stat. § 432.230 lets electronic records and signatures satisfy writing
and signature requirements. Mo. Rev. Stat. § 432.235 requires delivered information to
be printable or storable; if the sender inhibits that ability, the electronic
record is not enforceable against the recipient. Mo. Rev. Stat. § 432.250 recognizes an
electronic acknowledgment or notarization when the authorized person's
electronic signature and the other required information are attached or
logically associated.

Required copy or written statement

The surveyed provisions state no general duty to deliver a fully executed lease
copy. Mo. Rev. Stat. § 535.185 instead requires the landlord or authorized
leasing person, at or before commencement, to disclose in writing the name and
address of the property manager and an owner or owner-authorized person for
service of process and receipt of notices and demands. The information must be
kept current and binds successor landlords, owners, and managers.

Failure makes the nondisclosing person an agent of each landlord for the
purposes listed in the statute, including service, notices, landlord
obligations, and availability to collect rent.

Renewal, modification, assignment, and surrender

A renewal or extension longer than one year, or not performable within one year
after making, follows § 432.010's signed-writing rule. If a residential-building
agreement is unwritten and unsigned by the parties or agents, § 441.060.3 gives
it month-to-month status instead of the claimed fixed term.

Missouri separately addresses later transfers and endings. Mo. Rev. Stat. § 432.060 says
a lease or leasehold interest may not be assigned, granted, or surrendered
unless by deed or written note signed by the person taking that action, an agent
with written authority, or operation of law.

Recording and third-party effect

Missouri's general recording statutes state no lease-duration threshold.
Mo. Rev. Stat. § 442.380 directs an acknowledged or proved and certified written
instrument affecting real estate to the recorder of the county where the land
is located. Section 442.130 also requires a written instrument conveying a real-
estate interest to state whether each natural person executing it is married or
unmarried.

Under § 442.390, filing gives notice to everyone and charges later purchasers
and mortgagees with that notice. Section 442.400 preserves an unrecorded
instrument between its parties and against people with actual notice, but not
against others. The surveyed statutes state no lease-specific memorandum or
notice alternative.

Effect of noncompliance

The consequences are cumulative but different. Section 432.010 supplies the
no-action rule for a covered unsigned agreement. Sections 432.050 and 441.060.3
reduce an unwritten lease to at-will or, for the ordinary residential-building
setting, month-to-month status. Section 432.060 requires writing for an
assignment, grant, or surrender.

Nonrecording has the separate third-party consequence in § 442.400. Failure to
provide § 535.185's contact information creates the narrower statutory agency
described there.

What trips people up

One year is not the only writing line. The action bar starts above one year,
but § 441.060.3 treats an unwritten house or building lease as month-to-month
even when the claimed fixed term is shorter.

Both-party form and party-charged enforcement are different tests. A
signature from the party to be charged can satisfy § 432.010 for an action,
while § 441.060.3 asks for the parties' or their agents' signatures to preserve
the residential fixed-term form.

Assignments and surrenders have their own statute. Section 432.060 requires
a signed deed or written note even when the original lease term itself would
not cross § 432.010's one-year line.

Common questions

Can an oral one-year residential lease stay fixed for one year? Missouri's
no-action rule says “longer” than one year, but § 441.060.3 separately makes an
unwritten house or building agreement a month-to-month tenancy. The two rules
answer different questions.

Must a Missouri lease be notarized? Not to bind the original parties under
the surveyed writing statutes. An acknowledgment or proof and certification is
needed when the written instrument is placed in the land records.

Does an unrecorded lease still bind the landlord and tenant? Section
442.400 preserves it between the parties and against people with actual notice.
Recording adds constructive notice to others under § 442.390.
