South Dakota: Residential Lease Execution Formalities

Requirements one by one

Governing law and scope

South Dakota defines leasing in § 43-32-1 and places its lease-specific writing,
modification, and renewal rules in chapter 43-32. Section 53-8-2 is the general
statute of frauds, § 53-8-7 controls alteration of written contracts, chapter
53-12 governs electronic transactions, and chapter 43-28 governs recording and
third-party effect.

This page covers an ordinary private dwelling lease. Agricultural, public,
commercial, mobile-home, and specialized transactions can follow other rules.

Writing threshold

Section 43-32-5 makes an agreement to lease real property for longer than one
year invalid unless the lease, note, or memorandum is written and signed in the
specified way. Section 53-8-2 independently makes a lease longer than one year
unenforceable by action without its prescribed writing and signature.

The general statute of frauds also reaches an agreement that, by its terms,
cannot be performed within one year after making. Thus a delayed-start term can
trigger § 53-8-2 even when the period of occupancy itself is not over one year.
For lodgings with no stated duration, § 43-32-4 follows the rent interval, or
presumes a monthly term when the parties made no time agreement.

Required signatures and authority

South Dakota uses two signature formulations. For validity, § 43-32-5 requires
the long lease, note, or memorandum to be signed by the lessor or by the
lessor's agent authorized in writing.

For an enforcement action, § 53-8-2 requires subscription by the party to be
charged or that party's agent, with the agency authorization also written. A
landlord signature alone therefore does not automatically satisfy the separate
statutory requirement when enforcement is sought against an unsigned tenant.

Witness, acknowledgment, and notary

Sections 43-32-5 and 53-8-2 state no witness, acknowledgment, notarization, or
seal condition for validity or enforcement between the original parties. They
focus on the written instrument and the required signer.

Recording is different. Section 43-28-8 ordinarily requires the person
executing the instrument to acknowledge it, or permits execution to be proved
and certified under the referenced procedures. That is a recordability step,
not a rule that every ordinary lease must be notarized to bind landlord and
tenant.

Electronic execution

Chapter 53-12 applies to electronic transaction records and signatures under
§§ 53-12-2 and 53-12-3. Under § 53-12-7, electronic use is not forced, and
§ 53-12-8 applies the chapter only when each party agrees to transact
electronically.

Under § 53-12-13 through § 53-12-16, electronic records and signatures retain
legal effect and satisfy writing and signature requirements. Under
§§ 53-12-17 and 53-12-19, a required electronic delivery must remain printable
or storable when received; blocking retention makes it unenforceable against
the recipient.

Required copy or written statement

The current chapter 43-32 lease provisions state no general deadline for a
landlord to give the tenant a fully executed copy and no general duty to issue
a basic owner, manager, or payment-information statement at lease formation.

That absence does not eliminate separate transaction-specific disclosures or
a promise in the parties' own lease. It means the ordinary execution statutes
surveyed here do not create a statewide signed-copy delivery rule.

Renewal, modification, and term form

Under § 53-8-7, a written contract may be altered by another written contract
or by an executed oral agreement, and not otherwise. For month-to-month leases,
§ 43-32-13 lets the landlord modify terms by written notice at least 30 days
before month-end. If the tenant stays, the noticed terms become part of the
lease; the tenant may instead terminate by notice within 15 days after receipt.

Section 43-32-14 addresses holdover. When the tenant remains after expiration
and the landlord accepts rent, the law presumes renewal on the same terms and
for the same time, but never beyond one year. Under § 43-32-15, the statute
supplies the notice rule for an unstated term before that implied renewal
occurs.

Recording and third-party effect

Section 43-28-1 permits an instrument affecting title to or possession of real
property to be recorded in the county where the property lies. Section 43-28-8
requires acknowledgment or the statutory proof-and-certification route before
ordinary recording, and § 43-28-15 makes the record constructive notice to
later purchasers and encumbrancers.

The threshold is longer than one year. Under § 43-28-17, only a lease not
exceeding one year is excluded from the recording-priority rule. An unrecorded longer
lease remains valid between the parties and people with notice under
§ 43-28-14, but it is void against a later purchaser or encumbrancer who acts in
good faith, pays value, and records first. Chapter 43-28 states no lease-specific
memorandum or notice-of-lease alternative.

Effect of noncompliance

Section 43-32-5 calls a lease longer than one year invalid without the written
instrument and lessor-side signature it specifies. Section 53-8-2 separately
says a covered contract is not enforceable by action without a writing
subscribed by the party to be charged or that party's properly authorized
agent.

Failure to record has a different consequence. Sections 43-28-14 and 43-28-17
preserve effect between the original parties and people with notice, while
allowing a later protected purchaser or encumbrancer whose conveyance is first
duly recorded to prevail.

What trips people up

The two signature statutes ask different questions. Section 43-32-5 speaks
to validity and names the lessor. Section 53-8-2 speaks to enforcement by action
and names the party to be charged.

Holdover renewal has a one-year ceiling. Even if the expired lease was
longer, § 43-32-14's presumed renewal from continued possession and accepted
rent cannot exceed one year.

Acknowledgment belongs to the recording layer. A notary is not a general
between-party lease requirement, but § 43-28-8 ordinarily requires an
acknowledgment or proof before the instrument can be recorded.

Common questions

Can a South Dakota residential lease be oral?

Yes for a term not exceeding one year under the lease-duration rule, but an
agreement that cannot be performed within one year after making can still fall
under § 53-8-2.

Who must sign a lease longer than one year?

Section 43-32-5 requires the lessor or a lessor's agent authorized in writing.
For enforcement against a particular person, § 53-8-2 also requires that
person's subscription or the signature of that person's agent authorized in
writing.

Must the tenant receive a signed copy?

South Dakota's current ordinary lease chapter states no general executed-copy
delivery deadline. The parties' agreement or another transaction-specific law
can still require one.

Does an unrecorded lease remain valid?

Yes between the parties and people with notice. For a lease longer than one
year, nonrecording can allow a later good-faith purchaser or encumbrancer for
value who records first to prevail.
