Colorado authorities and version notes

CO01. PSI — Colorado Real Estate Candidate Information Bulletin

. .

The retrieved bulletin cover is dated October 1, 2023. Its national/state question counts, times, passing counts, and state blueprint are the published basis for this edition’s practice structure. This is not a claim that a revised 2026 bulletin was retrieved. Check current instructions, accommodations, fees, identification, and administration policies before registration.

CO02. Colorado Secretary of State — 4 CCR 725-1 rule history and 2026 revision

. .

The official index identifies a revision effective January 30, 2026. The complete revised consolidation was not retrievable during preparation. Accessible older rule reproductions below must not be mistaken for a verified complete 2026 consolidation. Special portability, reactivation, and continuing-education pathways require confirmation against the current official text.

CO03. Colorado Real Estate Commission Rules — Chapter 2, Licensure

.

Education allocation, application, examination validity, experience, and license pathways. The accessible reproduction displays older revision information. Read with CO02, the licensing statute at CO33, and applicable 2026 legislation; do not use it alone to decide a special 2026 eligibility pathway.

CO04. Colorado Real Estate Commission Rules — Chapter 3, License Maintenance

.

Active and inactive status, renewal, errors-and-omissions requirements, and associated maintenance duties. Older accessible reproduction; current official revisions control. Individual policy coverage, insurer exclusions, and limits must be checked separately.

CO05. Colorado Real Estate Commission Rules — Chapter 4, Continuing Education

.

Ordinary 24-hour continuing-education framework, Annual Commission Updates, and related pathways. Older accessible reproduction. Verify initial-license, reactivation, military-portability, and other exceptions against the 2026 official rules rather than assuming every licensee follows the ordinary cycle.

CO06. Colorado Real Estate Commission Rules — Chapter 5, Money Belonging to Others

.

Trust and escrow account structure, funds receipt and deposit, property management, accounting, reconciliation, and disbursement. The discussion distinguishes ordinary and property-management funds and the relevant later-of-receipt-or-mutual-execution trigger. Older accessible reproduction; check official revisions.

CO07. Colorado Real Estate Commission Rules — Chapter 6, Practice

.

Competence, relationships, advertising, supervision, square footage, conflicts, transaction duties, and records. Older accessible reproduction. Relationship creation and confidentiality discussions must also incorporate CO09 and CO10, which amend the statute in 2026.

CO08. Colorado Real Estate Commission Rules — Chapter 7, Forms

.

Approved forms, permitted exceptions, preparation limits, and advice concerning principal-prepared contracts. Older accessible reproduction. Read the principal-contract discussion together with the new statutory provision in CO09.

CO09. HB26-1426 — 2026 amendments affecting brokerage agreements and principal-drafted contracts

. .

Sections 87–89 are particularly relevant. Section 87 replaces the former default-transaction-broker language in § 12-10-403(2) with a written-agreement requirement for both single agency and transaction-brokerage, including conspicuous compensation terms before covered brokerage activities. Section 89 adds § 12-10-408.5 on principal-created purchase contracts and the stated disclosure of broker unilateral-cancellation clauses. The act’s effective-date provision identifies August 12, 2026, subject to its referendum condition. The official enacted history is the basis for the current-law treatment in this edition; this does not establish the update date of a confidential examination item bank.

CO10. HB26-1287 — Sunset review of the Division of Real Estate

. .

Effective August 12, 2026 under the enacted effective-date clause. Relevant changes include the post-revocation application interval, continuing-education inactivation authority, affiliated-business disclosure timing, supervisory sharing of confidential information, and express-written-consent wording. Apply the actual amended section; an older consolidated reproduction may still display superseded wording.

CO11. Colorado Commission residential purchase contract — 2026 CBS1

. .

The form states adoption August 5, 2025 and use on or after January 1, 2026. The full form was read through the public mirror because direct Division retrieval was blocked. Contract terminology, selections, deadlines, inspection routes, deed, and settlement provisions in this book refer to that version. A broker must still obtain the form version applicable to the transaction and read all completed terms; this manuscript does not reproduce a completed legal contract.

CO12. Colorado Commission residential foreclosure purchase contract — 2026 CBSF1

.

Specialized Commission form designated for use beginning January 1, 2026, retrieved through a public mirror. Its warnings and statutory cancellation provisions do not make it appropriate for every distressed-property transaction. Read with the applicable Foreclosure Protection Act, including CO32.

CO13. C.R.S. § 24-34-502 — Colorado housing discrimination

.

State protected characteristics and prohibited housing practices, including separate source-of-income provisions and exceptions. This state list is not interchangeable with the federal Fair Housing Act or with protected categories under an unrelated employment statute.

CO14. C.R.S. § 38-12-103 — Residential security-deposit return and accounting

.

Read the version effective January 1, 2026, not only the earlier text appearing on the same page. Covers the 30-day ordinary return rule and maximum 60-day lease extension, deductions, documentation, remedies, transfer, and specified exceptions. This is a landlord–tenant return rule, not the broker’s deadline for depositing funds into a trust account.

CO15. HB25-1249 — Security-deposit protections effective in 2026

. .

Enacted changes to residential security-deposit treatment effective January 1, 2026. Read with the amended statute in CO14. The book distinguishes actual damage from ordinary wear and preexisting conditions and flags documentation and other statutory qualifications.

CO16. C.R.S. § 37-90-143 — Well owner contact updates

.

The 63-day requirement concerns a well owner’s name or contact-information change. It is not the same trigger as the 60-day fallback ownership-change filing described in the residential purchase form at CO11.

CO17. C.R.S. § 39-22-604.5 — Withholding on certain real estate transfers

.

Colorado nonresident-transfer withholding, the lesser-of-sales-price-percentage-or-net-proceeds calculation, and statutory exceptions. A price not exceeding $100,000 is one specified exception. This withholding is distinct from federal FIRPTA and is not a simple tax of two percent of gain.

CO18. C.R.S. § 39-13-102 — Documentary fee

.

Fee on covered recorded conveyances: one cent per $100 or major fraction of qualifying consideration exceeding $500. Separate recording fees and local transfer charges may have different rules. Examples using exactly divisible consideration avoid silently replacing the statutory fractional standard with a different rounding rule.

CO19. C.R.S. § 12-10-206 — Commission composition

.

Five-member Commission, broker and public-member composition, experience requirements, appointment, and terms. A private trade association is not the state licensing Commission.

CO20. C.R.S. § 12-10-217 — Broker discipline

.

Grounds and mechanisms for discipline, including separate-offense administrative fines and records duties. Read with CO10 for 2026 amendments; an older version’s post-revocation interval must not override the enacted change.

CO21. C.R.S. § 38-38-104 — Cure of default

.

Persons entitled to cure, notice, cure amounts, and payment timing in the covered foreclosure process. The ordinary notice period and noon-before-sale payment cutoff are distinct from an equity-purchase cancellation right or junior-lienor redemption.

CO22. C.R.S. §§ 12-10-501 and 12-10-503 — Subdivision developer regulation

. .

Definition, exceptions, and registration framework for covered subdivision development. Do not turn a general threshold into a claim that every division of land must register. Read with continuation and amendment provisions in CO10.

CO23. C.R.S. § 37-92-102 — Water-right principles

.

State water-law framework and priority principles. The book presents an exam-level distinction between owning land and holding water rights; individual rights, decrees, well permits, groundwater classifications, and changes of use require specialized analysis.

CO24. C.R.S. § 12-10-403 — Brokerage relationships and designation

.

Relationship framework, prohibited dual agency, and designation. IMPORTANT: the accessible consolidated text may retain the former default-transaction-broker provision. For current § 12-10-403(2), use the enacted replacement in CO09, not the superseded language; for supervisory confidentiality use CO10.

CO25. C.R.S. § 12-10-404 — Seller’s and landlord’s agent duties

.

Agency duties, disclosures, confidentiality, and duties toward other parties. Read the confidentiality wording with CO10’s 2026 express-written-consent amendment.

CO26. C.R.S. § 12-10-405 — Buyer’s and tenant’s agent duties

.

Agency duties, disclosure, accounting, confidentiality, and expert-advice issues on the buyer or tenant side. Read with the 2026 amendments in CO10.

CO27. C.R.S. § 12-10-407 — Transaction-broker duties

.

Nonagency brokerage duties, assistance, accounting, material facts, and confidential information. The current written relationship-creation requirement is supplied by CO09. Do not read an older reference to an oral agreement as permission to disregard the new written-agreement requirement.

CO28. C.R.S. § 38-12-1303 — Cause for residential eviction

.

Qualifying cause, defined no-fault grounds, notices, and conditions for covered residential tenancy termination. Exceptions and other statutes matter. The book does not present one notice length as universally sufficient for every tenancy or every ground.

CO29. C.R.S. § 38-12-503 — Warranty of habitability

.

Residential habitability obligations and remedial process. A broker should identify the issue and obtain appropriate legal and technical assistance rather than improvise a lockout, utility shutoff, or supposed waiver of statutory duties.

CO30. C.R.S. § 38-35.7-112 — Radon disclosure

.

Colorado residential radon disclosure, warning, available information, and related requirements. The statutory citation uses a period in 38-35.7; the publisher URL encodes it with an underscore.

CO31. C.R.S. § 38-38-302 — Redemption by eligible lienors

.

Eligibility, notices, payment, priority, and timing for the specified post-sale redemption process. Do not equate this with a universal homeowner post-sale redemption right or assume every lien, foreclosure type, and claimant follows an identical route.

CO32. C.R.S. § 6-1-1113 — Cancellation of a covered equity-purchase contract

.

The specified homeowner cancellation period ends at midnight of the third business day after signing a complying contract or noon on the day before the foreclosure sale, whichever occurs first. It is not an 8 a.m. sale-day cutoff. Use the Act’s definitions, delivery rules, and coverage requirements.

CO33. C.R.S. § 12-10-203 — Broker application and qualifications

.

Minimum age, fingerprints, education, examination, independent practice, employing-broker preparation, and brokerage-entity requirements. Read with current Commission rules and CO10’s 2026 amendments; older legal-name wording is not used as current guidance in this edition.

CO34. C.R.S. § 12-10-201 — Broker activities and exemptions

.

Definition of compensated brokerage, including a single act, offer, or attempt, and specific exemptions. Owner, entity, attorney, fiduciary, on-site-manager, cooperative commission, and other exceptions have conditions. An exemption should be established from its actual elements rather than assumed from a job title. Read with applicable 2026 amendments in CO10.
