Delaware: Revocable Trust Amendment Requirements

Requirements one by one

The governing instrument supplies the power; § 3545 supplies a form rule

Delaware's Chapters 33 and 35 do not state a general rule making every ordinary
trust revocable or prescribing one UTC-style amendment method. Under 12 Del. C.
§ 3301(e), the "governing instrument" includes a trust agreement or declaration
and an instrument that modifies its terms. The instrument and other applicable
law therefore determine who holds an amendment power and any method it imposes.

A complete restatement is a comprehensive modification unless the governing
instrument or another applicable rule treats it differently. Delaware states no
separate ordinary-restatement procedure in the cited provisions.

Survivorship-contingent changes have two execution routes

Section 3545 applies under § 3545(a) when an amendment causes a person other than the trustor
to acquire or lose an interest whose possession or enjoyment depends on
surviving the trustor. Unless another Code rule applies, the change is void
without one of two writing routes.

Under the first route, the trustor executes the writing—or directs someone in
the trustor's presence to subscribe the trustor's name—and at least one
disinterested person or two credible persons witness in writing in the
trustor's presence. Under the second, a trustee who is disinterested executes
the writing, whether or not the trustor or anyone else signs.

A disinterested person has no beneficial interest that the change would
materially increase or decrease. A notary or similar official may count when
disinterested or credible, even if signing only in a notarial capacity.
Counterparts are allowed unless the writing expressly prohibits them, subject
to the witness requirements.

Changes outside the survivorship category

Under § 3545(c), a written modification outside subsection (a) is validly
executed if it uses the same writing and execution routes. The subsection also
preserves modification by any other means otherwise permitted by law, but does
not identify those means or create a general will, codicil, delivery, or
clear-and-convincing-intent fallback.

Under § 3550(a)–(b), a covered governing instrument or § 3545 document may be
executed electronically under Delaware's Uniform Electronic Transaction Act if
it is otherwise validly executed. Electronic form does not excuse the
applicable witness or disinterested-trustee route. Wills and codicils are
expressly excluded from this electronic-document provision.

Capacity and multiple trustors

The current ordinary-trust provisions state no general amendment-specific
cognitive standard and do not direct courts to use will capacity. They also
state no general contribution-based, community-property, joint-action, or
other-trustor-notice allocation. Those questions require the governing
instrument and other applicable law rather than importing a Uniform Trust Code
default.

Agent and court-supervised fiduciaries

Under 12 Del. C. § 49A-201(b)(1), an agent may amend an inter vivos trust only
if the personal power of attorney expressly grants that authority. The agent
may act only to the extent the principal could act, and not when another
agreement or instrument governing the authority or property prohibits the
exercise.

The current ordinary-trust provisions state no parallel general route allowing
a guardian or conservator to exercise a trustor's amendment power. A particular
court order or governing instrument may change the analysis.

Optional notice and the contest period

Section 3546(a)(1) permits the trustee to send a written notice about the trust
or amendment. A compliant notice identifies the trust's existence, the
trustee's name and address, whether the recipient is a beneficiary, and the
time allowed to contest.

The notice is treated as given when sent and ordinarily presumed received
seven days later. It can start a 120-day contest period, subject to another
listed bar occurring first. The statute expressly says the trustee has no
liability for failing to send the notice. This is an optional contest-limitation
tool, not a stated condition for the amendment to become effective.

What trips people up

• Inventing a Delaware revocability default. The cited current provisions
  state no general rule that every trust is revocable unless labeled otherwise.
• Requiring both trustor and trustee signatures. Under § 3545(a), Delaware supplies
  alternative routes; a disinterested trustee may execute without another
  person's signature.
• Using witness lines but not checking disinterest. One witness must be
  disinterested, or two credible persons must witness in writing in the
  trustor's presence.
• Adding delivery as a universal statutory condition. Section 3545 states
  execution routes, not a universal trustee-delivery rule.
• Treating electronic signing as a substitute for execution. Section 3550
  applies only when the document is otherwise validly executed.

Common questions

Must every Delaware amendment have witnesses?

No. For a covered survivorship-interest change, the trustor-execution route
requires the stated witnesses, but a disinterested trustee may instead execute
the writing. Section 3545(c) preserves other lawful means for changes outside
that category.

Does a notary replace all witnesses?

A notary may serve as a witness when disinterested or credible. One
disinterested person is enough; otherwise the trustor route requires two
credible persons. The notary's title alone does not answer the disinterest or
credibility question.

Can an agent sign the amendment?

Only if the personal power of attorney expressly grants authority to amend an
inter vivos trust, the principal has the authority, and another governing
agreement or instrument does not prohibit the exercise.

Must the trustee send the 120-day notice?

No. Section 3546 expressly creates no trustee liability for omitting it. A
compliant notice can shorten the contest period; it is not a universal
effectiveness requirement.
