Revocable Trust Amendment Requirements in Colorado

At a glance

Requirements one by one

Governing law and revocability presumption

C.R.S. § 15-5-602(1) permits amendment unless the trust terms expressly provide that the trust is irrevocable. That default does not apply to a trust created under an instrument executed before August 7, 2013.

The cutoff makes the instrument's execution history material. The current default does not itself establish amendment authority for every older Colorado trust.

Who may amend or restate

The settlor is the ordinary actor. Subsections (5) and (6) separately provide limited routes for an expressly authorized agent and a court-approved conservator or fallback guardian. Trustee or beneficiary status alone does not confer amendment authority.

Colorado states no distinct lifetime-restatement route. A complete restatement is a comprehensive amendment and must satisfy the same authority and method rules.

Trust method and exclusivity

The settlor may substantially comply with a method supplied by the trust. If the trust provides no method or its method is not expressly exclusive, the statutory intent alternative remains available.

Colorado defines the exclusivity signal. A method is not exclusive unless it is called the "sole," "exclusive," or "only" method, or the provision uses similar language manifesting an intent to bar every other method.

Alternative intent or will method

When the trust method is absent or nonexclusive, subsection (3)(b) recognizes any other method manifesting clear and convincing evidence of the settlor's intent. That method may include a later will or codicil that expressly refers to the trust or specifically devises property that otherwise would pass under it.

The will example is part of the broad intent route. Colorado does not list it as a separate alternative with a different proof standard.

Signature, witnesses, notary, and delivery

The trust's own method controls its required execution or delivery acts. When the statutory alternative is available, § 15-5-602(3)(b) turns on clear and convincing evidence of intent and can include the qualifying will or codicil.

The section states no universal amendment-specific writing, signature, witness, acknowledgment, notarization, trustee-delivery, or trustee-acceptance rule. A particular exclusive trust method can still require one or more of those acts.

Capacity standard

Colorado did not enact the common Trust Code capacity sentence. C.R.S. § 15-5-601 is marked "Reserved," and § 15-5-602 supplies no replacement age, will-capacity, contract-capacity, or functional formula for amendment.

That statutory gap should not be filled by assuming the rule used in another state. Capacity questions require the current law applicable outside the cited Trust Code provisions and the facts of the particular decision.

Multiple settlors and contributed property

Community-property amendment requires both spouses acting jointly. For other property, each settlor may amend the portion attributable to that settlor's contribution.

The community-property revocation sentence also limits one spouse's unilateral action to the portion attributable to that settlor's contribution. When fewer than all settlors revoke or amend, the trustee must promptly notify the others.

Agent, guardian, conservator, and court authority

An agent may exercise amendment powers to the extent expressly authorized by the trust terms or the power of attorney. Colorado uses an either-document rule; it does not require the express grant in both.

Unless the trust provides otherwise or another person holds an express grant, a conservator—or a guardian if no conservator has been appointed—may act only with approval from the court supervising that fiduciary.

Effective time, notice, and trustee protection

The applicable trust method or statutory intent route determines when its required acts are complete. Section 15-5-602 states no general beneficiary- notice or trustee-acceptance condition, but subsection (2)(c) requires prompt notice to the other settlors when fewer than all act.

Under subsection (7), a trustee without knowledge of an amendment is not liable to the settlor or successors for distributions and other actions taken on the assumption that the old terms remain operative.

What trips people up

• Assuming ordinary method language is exclusive. Colorado requires words such as "sole," "exclusive," or "only," or similar intent language.
• Importing a will-capacity rule into reserved § 15-5-601. The current Trust Code supplies no special amendment-capacity formula.
• Demanding express agent authority in two documents. The trust or the power of attorney may supply it.
• Skipping the fiduciary hierarchy. The conservator acts first; a guardian's statutory route exists only if no conservator has been appointed, and court approval remains necessary.

Common questions

Can a trust make its stated amendment method exclusive without using one of the three listed words?

Yes, if it uses similar language manifesting the settlor's intent that no other method may be used. The statute lists "sole," "exclusive," and "only" as examples, not as the only possible wording.

Does the absence of a Trust Code capacity formula mean capacity never matters?

No. It means §§ 15-5-601 and 15-5-602 do not supply a special formula for this survey to report. The applicable law and facts still determine whether the settlor could validly exercise the amendment power.
