Iowa: Residential Lease Execution Formalities

Requirements one by one

Writing threshold

Iowa Code § 622.32 makes evidence of specified contracts incompetent unless the
agreement is written and signed by the party charged or that party's authorized
agent. The listed contracts include creating or transferring a land interest,
except a lease for a term not exceeding one year, and an agreement not
performable within one year after making.

An exactly one-year lease is therefore within the land-interest exception. A
delayed start or other terms can still trigger the separate one-year-from-making
test. Iowa Code § 562A.6(3), (5), (11), and (16) supplies the residential
definitions and expressly includes written and oral rental agreements.

Required signatures and authority

Section 622.32 uses the party-to-be-charged rule and expressly permits that
party's authorized agent to sign. Iowa's residential act then provides a
conduct-based cure for a written agreement missing one side's signature and
delivery.

Under Iowa Code § 562A.10, a landlord who accepts rent without reservation gives
the tenant-signed and delivered agreement the same effect as if the landlord had
signed and delivered it. A tenant who accepts possession without reservation
does the same for a landlord-signed and delivered agreement. If the cured
agreement states a term longer than one year, it is effective for only one year.

Witness, acknowledgment, and notary

Sections 622.32 and 562A.10 state no witness, acknowledgment, seal, or notary
condition for party-to-party effect. The residential conduct rule itself focuses
on signature, delivery, rent acceptance, and possession acceptance.

Recording has a separate form. Iowa Code § 558.20 routes acknowledgment of an
instrument conveying or encumbering Iowa real estate through chapter 9B, and
Iowa Code § 558.42 says a document is not lawfully recorded unless previously
acknowledged or proved under that chapter, subject to listed exceptions not
relevant to an ordinary lease.

Electronic execution

Iowa's UETA applies to ordinary electronic lease records and signatures under
Iowa Code § 554D.104. Iowa Code § 554D.106(1)-(2) makes the method voluntary:
each party must agree, as determined from the context, surrounding circumstances,
and conduct.

Iowa Code § 554D.108 lets an electronic record satisfy a writing requirement and
an electronic signature satisfy a signature requirement. When a required written
record is delivered electronically, § 554D.110(1), (3) requires a form the
recipient can print or store and makes a retention-blocked record unenforceable
against that recipient. Iowa Code § 554D.113 recognizes an electronic
acknowledgment when the authorized person's signature and other required
information are attached or logically associated with the record.

Required copy or written statement

Chapter 562A states no general deadline for giving the tenant a fully executed
copy. Section 562A.10 instead explains when an unsigned or undelivered written
rental agreement receives effect through rent or possession acceptance and caps
a longer stated term at one year.

Iowa Code § 562A.13(1)-(3) separately requires a written identification at or
before commencement. It must name and address the premises manager and an owner
or authorized owner representative who can receive service, notices, and
demands. The information must remain current and applies to successors.

Renewal, modification, and term form

The cited statutes state no separate form for every renewal or modification.
The general § 622.32 tests still apply if the later agreement creates or
transfers a land interest outside the one-year lease exception or cannot be
performed within one year after it is made.

Section 562A.10 remains the residential consequence when the parties exchange a
written agreement but one side does not complete signature and delivery: conduct
can give it effect, but not beyond one year under that section.

Recording and third-party effect

Iowa Code § 558.1 treats instruments relating to real estate as instruments
affecting real estate. Iowa Code § 558.41(1) then says such an instrument has no
validity against a later purchaser for valuable consideration without notice
unless it is filed and recorded in the county where the property is located.

Section 558.42 makes acknowledgment or proof under chapter 9B a condition to
lawful recording. The general provisions state no lease-term threshold or
prescribed lease-memorandum alternative. Recording is therefore a third-person
priority step, distinct from § 562A.10's effect between landlord and tenant.

Effect of noncompliance

Iowa uses an evidence consequence in § 622.32: without the required signed
writing, evidence of the listed agreement is incompetent. Section 562A.10 can
give an exchanged written residential agreement effect through acceptance of
rent or possession, but limits a stated term longer than one year to one year.

The written-identity provision has its own result. Under § 562A.13(3), a person
who fails to provide the information becomes the landlord's agent for service,
notices, landlord obligations, and use of collected rent. Nonrecording has the
separate § 558.41 consequence against later purchasers for value without notice.

What trips people up

An unsigned agreement can still operate. Acceptance of rent or possession
without reservation can supply the missing landlord or tenant effect under
§ 562A.10, but it cannot carry a term longer than one year through that route.

Exactly one year is on the short side. Section 622.32 excepts leases not
exceeding one year from its land-interest category; the separate performance
test can still matter when the agreement cannot finish within one year of making.

Recording acknowledgment is not a signing ceremony. The acknowledgment or
proof requirement belongs to lawful recording under § 558.42, not to the basic
residential conduct rule in § 562A.10.

Common questions

Must Iowa landlords give tenants a signed copy by a fixed deadline? Chapter
562A states no general executed-copy deadline. It addresses signature and
delivery through § 562A.10 and requires written manager and owner-contact
information by commencement under § 562A.13.

Can an Iowa lease be signed electronically? Yes, when the parties agree to
transact electronically. Any electronically delivered required writing must be
printable or storable under § 554D.110.

Does an unrecorded lease remain effective between landlord and tenant? The
recording statute addresses later purchasers for value without notice. Between
the original parties, the writing and conduct rules in §§ 622.32 and 562A.10
remain the relevant form provisions.
