Colorado: Revocable Trust Amendment Requirements
The short answer
Colorado generally permits amendment unless the trust expressly says it is irrevocable, but that default does not apply to an instrument executed before August 7, 2013. The settlor may substantially comply with the trust's method or, unless that method is expressly exclusive, use another method manifesting clear and convincing evidence of intent; Colorado defines exclusivity through words such as "sole," "exclusive," or "only," or similar language. The Trust Code reserves its capacity section rather than supplying a special amendment-capacity formula, while contribution-based co-settlor rules, either-document agent authority, conditional court-supervised fiduciary authority, prompt co-settlor notice, and a no-knowledge trustee safe harbor also apply.

| Governing law and revocability presumption | C.R.S. § 15-5-602; amendable unless terms expressly say irrevocable. Default excludes instruments executed before Aug. 7, 2013 |
|---|---|
| Who may amend or restate | Settlor; expressly authorized agent; conservator or fallback guardian with court approval unless trust terms or another express grant displace that route. Restatement is comprehensive amendment |
| Trust method and exclusivity | Substantial compliance with trust method; alternative remains if method absent/nonexclusive. Exclusive means sole, exclusive, only, or similar intent language (§ 15-5-602(3)) |
| Alternative statutory method | If method absent/nonexclusive, any method manifesting clear-and-convincing intent, including qualifying later will/codicil (§ 15-5-602(3)(b)) |
| Signature, witnesses, notary, and delivery | Trust method controls its formalities; fallback is any proven method and may include qualifying will/codicil. No universal amendment writing, signature, witness, notary, or trustee-delivery rule |
| Capacity standard | C.R.S. § 15-5-601 is reserved; the Trust Code states no special amendment-capacity formula |

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.
