Colorado: Residential Lease Execution Formalities
The short answer
Colorado allows an oral residential lease for one year or less, but a lease longer than one year must be written and subscribed by the landlord or a lawfully authorized agent with written authority (C.R.S. §§ 38-10-106, -108, -109). No witness or notary is required for the lease itself; electronic records and signatures work by party agreement, and a written residential lease copy signed by landlord and tenant must reach the tenant within seven days after the tenant signs (§ 38-12-801). Recording is optional between the parties but protects the lease against later claimants under Colorado's race-notice rule (§ 38-35-109).

| Governing law and scope | C.R.S. §§ 38-10-106, -108, -109 (land-interest writing and agent authority); § 38-12-801 (residential signed-copy and landlord-identity duties); §§ 24-71.3-103, -105, -107, -108 (electronic transactions); §§ 38-35-106, -109 (recording). Ordinary private dwelling rentals (§ 38-12-902) |
|---|---|
| Writing threshold | A lease longer than 1 year is void unless the contract, note, or memorandum states the consideration, is written, and is subscribed by the party making the lease (§ 38-10-108). A lease not exceeding 1 year is outside § 38-10-106's land-interest writing rule |
| Required signatures and authority | Longer lease: signature of the party creating/making the lease—ordinarily the landlord—or an agent authorized in writing (§§ 38-10-106, -109). Separate copy duty: the tenant must receive an agreement signed by both landlord and tenant (§ 38-12-801(1)) |
| Witness, acknowledgment, and notary | No witness, acknowledgment, or notary required to execute the lease; §§ 38-10-106/-108 require a subscribed writing only. Even an unacknowledged written real-property instrument gives notice after recording (§ 38-35-106) |
| Electronic execution | Allowed only when both parties agree to transact electronically (§ 24-71.3-105). Electronic records/signatures satisfy writing/signature rules (§ 24-71.3-107); delivered records must be printable or storable (§ 24-71.3-108). Primary-residence default, eviction, and cure notices are excluded (§ 24-71.3-103(3)(b)(II)) |
| Required copy or written statement | Within 7 days after the tenant signs, landlord must give a copy signed by landlord and tenant; electronic is allowed unless tenant requests paper (§ 38-12-801(1)). Written lease must state landlord/authorized agent name and address; a change requires notice or conspicuous posting within 1 business day (§ 38-12-801(2)) |
| Renewal, modification, and term form | No separate statewide renewal form in these sections. A contract leasing for longer than 1 year remains subject to § 38-10-108; creating, assigning, or surrendering a land interest requires a signed writing or operation of law, with written agent authority (§ 38-10-106) |
| Recording and third-party effect | Optional between the original parties. A written agreement affecting real-property title may be recorded with the county clerk and recorder; an unrecorded lease loses to a later rights-holder who records first without prior notice. Colorado expressly calls this race-notice (§ 38-35-109(1)); no lease-specific memorandum form or term threshold is stated |
| Effect of noncompliance | A lease longer than 1 year is 'void' without the § 38-10-108 writing, consideration, and subscribing signature; § 38-10-106 does not create/assign/surrender the land interest without its signed writing. Section 38-12-801(1) imposes the 7-day signed-copy duty but states no lease-invalidity consequence for a late or missing copy |

Requirements one by one
Writing threshold
Colorado draws the line at more than one year. C.R.S. § 38-10-108 says a
contract leasing land for a longer period is void unless the contract—or a note
or memorandum expressing the consideration—is written and subscribed by the
party making the lease. Section 38-10-106 makes the same dividing line from the
property-interest side: leases not exceeding one year are excluded from its
signed-writing rule.
That means a one-year lease is on the short side of the line; the trigger is a
term longer than one year. C.R.S. § 38-12-902 confirms that Colorado's residential
"rental agreement" can be written or oral and concerns the use and occupancy of
a dwelling unit.
Required signatures and authority
For the longer lease, § 38-10-108 asks for the signature of the party by whom the
lease is made. Section 38-10-106 similarly requires the signature of the party
creating the land interest or that party's agent with written authority. C.R.S.
§ 38-10-109 lets an agent subscribe the instrument required by § 38-10-108 only
when the agent is lawfully authorized in writing.
Colorado's residential copy rule answers a different question. Under
§ 38-12-801(1), the copy delivered to the tenant must be signed by both landlord
and tenant. That both-signature copy duty does not rewrite § 38-10-108's separate
rule about which signature satisfies the land statute of frauds.
Witness, acknowledgment, and notary
Sections 38-10-106 and 38-10-108 require a subscribed writing but name no
witness, acknowledgment, seal, or notary for lease execution. Colorado also
recognizes an unacknowledged written real-property instrument after recording:
§ 38-35-106(1) says it gives notice even when acknowledgment is absent or
defective. Acknowledgment therefore is not what makes the lease enforceable
between landlord and tenant.
Electronic execution
Colorado's Uniform Electronic Transactions Act applies to ordinary lease
formation, but it does not force either party online. C.R.S. § 24-71.3-105 says
each party must agree to conduct the transaction electronically, with agreement
determined from context and conduct. C.R.S. § 24-71.3-107 then lets electronic
records and signatures satisfy writing and signature requirements.
Delivery must leave a usable record. Under § 24-71.3-108, electronically
delivered information must be printable or storable; if the sender inhibits
retention, the electronic record is not enforceable against the recipient. And
§ 24-71.3-103(3)(b)(II) excludes required primary-residence default,
acceleration, repossession, foreclosure, eviction, and cure notices. E-signing
the lease does not automatically authorize those later notices electronically.
Required copy or written statement
C.R.S. § 38-12-801(1) starts the clock when the tenant signs. No later than the
seventh day afterward, the landlord must provide a copy signed by landlord and
tenant. The landlord may deliver electronically unless the tenant requests
paper, in which case paper is required.
Section 38-12-801(2) adds an identity statement. The written agreement must give
the name and address of the landlord or authorized agent. If that identity
changes, the new landlord or agent has one business day to notify each tenant in
writing or electronically, or to post the new identity conspicuously at the
residential premises.
Renewal, modification, assignment, and surrender
The cited sections do not create a separate statewide renewal form. They keep
the form tied to the land interest instead. A contract leasing for longer than
one year remains within § 38-10-108. Section 38-10-106 separately requires a
signed writing to create, grant, assign, surrender, or declare a land interest,
unless the change occurs by act or operation of law; an agent needs written
authority.
Recording and third-party effect
Recording is not a condition for enforceability between the original parties.
C.R.S. § 38-35-109(1) permits written agreements or other instruments affecting
real-property title to be recorded with the county clerk and recorder where the
property lies. The section states no lease-specific term threshold or prescribed
memorandum form.
The consequence is priority. An unrecorded instrument remains effective between
its parties and against someone who had notice, but it is not valid against a
later rights-holder who records first without prior notice. Colorado calls this
its "race-notice recording statute." Section 38-35-106 separately confirms that
recording gives notice even if the instrument is unacknowledged or defectively
acknowledged.
Effect of noncompliance
The consequence in § 38-10-108 is direct: a longer lease is "void" without the
required writing, consideration statement, and subscribing signature. Section
38-10-106 likewise prevents creation, assignment, or surrender of the land
interest without its signed-writing route or operation of law.
The signed-copy subsection uses different language. Section 38-12-801(1) imposes
the seven-day delivery duty but does not say that a late or missing copy makes
the rental agreement void. Recording defects also concern priority against
third persons under § 38-35-109, not automatic invalidity between landlord and
tenant.
What trips people up
One year is included; longer than one year is the trigger. A term of exactly
one year is outside §§ 38-10-106 and 38-10-108's longer-lease writing rule.
The statute-of-frauds signature and the tenant's copy are different tests.
Section 38-10-108 focuses on the party making the lease, while § 38-12-801
requires the delivered residential copy to carry both parties' signatures.
Email does not defeat a paper request. An electronic copy is permitted, but
§ 38-12-801(1) requires paper when the tenant asks for it.
Common questions
Can an emailed signed copy satisfy Colorado law? Yes, when the parties have
agreed to transact electronically, the tenant has not requested paper, and the
record can be printed or stored under § 24-71.3-108.
Does recording excuse the landlord from giving the tenant a signed copy? No.
Recording addresses third-party priority under § 38-35-109; the seven-day copy
duty in § 38-12-801 applies separately.
May an eviction notice be sent electronically just because the lease was
e-signed? Not under the electronic-transactions act alone. Section
24-71.3-103(3)(b)(II) excludes required primary-residence default, eviction, and
cure notices from that act.
