Delaware: Irrevocable Trust Modification and Termination Requirements

Requirements one by one

A living trustor can join a broad written modification

Section 3342 permits a new provision or a change to an existing provision if it
could have been included in a trust created on the modification date. Every
trustor, every then-serving fiduciary, and every beneficiary having an interest
must provide written consent or written nonobjection. The modification may
violate a material purpose.

The route is unavailable when the governing instrument expressly prohibits
modification under § 3342, a § 3338 nonjudicial settlement or similar law, or a
modification agreement. An agent may exercise the trustor's consent power only
when the power of attorney or trust terms expressly authorize it. Otherwise, a
guardian of the trustor's property needs approval from the supervising court.
A fiduciary has no duty to consent.

Nonjudicial settlements use affected interested persons

Section 3338 permits the interested persons to make a binding nonjudicial
settlement concerning any trust matter. The affected group may include
fiduciaries, present and remainder beneficiaries, a living trustor, power
holders, and others whose rights arise from the governing instrument.

Without the trustor as a party, the agreement is valid only to the extent it
does not violate a material purpose. That restriction does not apply when the
trustor is a party. If the agreement alters a beneficial interest and includes
the trustor, all beneficiaries having an interest are included, and the trustor
normally cannot represent another beneficiary unless the statute's written
incomplete-gift confirmation applies. Any interested person may ask Chancery to
interpret, enforce, or determine the agreement's validity.

A protector's power must come from the instrument

Section 3313 does not give every protector an automatic modification power. It
recognizes the powers granted by the governing instrument, which may include
amending for favorable tax status, facilitating efficient administration, or
changing a beneficiary's power of appointment.

Cost-based termination has no dollar threshold

Section 3542 is captioned “Termination of small trusts,” but it sets no fixed
value ceiling. The operative test is whether administration costs would defeat
or substantially impair the trust's purpose. The trust terms may displace the
route, and the trustee exclusions in subsection (a) must be checked before
acting.

A qualifying trustee sends written notice to all interested persons or their
guardians. The notice states the intended termination, distribution plan,
30-day objection right, ability to proceed after further notice, and right to
apply to Chancery. After a timely objection, the trustee may reformulate and
renotify. If the trustee proceeds despite objection, further notice starts a
six-month court-petition and distribution-hold period unless everyone waives
the right in writing. A spendthrift term does not make § 3542 unavailable.

Written modifications can carry execution requirements

Section 3545 applies when a modification gives or removes another person's
interest whose possession or enjoyment depends on surviving the trustor. The
writing must be executed by the trustor with at least one disinterested or two
credible witnesses, or by a disinterested trustee. The same method is a
statutory safe harbor for other written modifications, while subsection (c)
preserves other methods otherwise permitted by law.

Representation depends on the particular conflict

Section 3547 allows specified minor, incapacitated, unborn, unascertainable,
remainder, and power-of-appointment interests to be represented in judicial and
nonjudicial matters. A substantially identical interest can bind another only
without a material conflict. The statute also presumes conflicts in listed
office-enhancement and other actual-or-potential-conflict situations.

What trips people up

• Section 3342 requires the serving fiduciaries as well as the trustor and
  beneficiaries; beneficiary agreement alone is not enough.
• The trust instrument can expressly turn off the living-trustor modification
  route.
• A trustor-party NJSA changes the material-purpose rule but can expand the
  beneficiary group and restrict the trustor's ability to represent others.
• Section 3542 has no dollar cap despite its “small trusts” caption.
• An objection does not create an absolute veto under § 3542, but it starts a
  six-month court-petition protection after further notice.

Common questions

Is Court of Chancery approval mandatory for a § 3342 modification?

No. The statute creates a written-consent or written-nonobjection route. An
interested person may later ask Chancery to interpret, enforce, or determine
its validity, including whether representation was adequate.

Can a protector change the trust for tax reasons?

Only if the governing instrument grants that power. Section 3313(f) lists tax-
status and efficient-administration changes as powers an instrument may give a
protector; it does not confer them merely from the title “protector.”

Does a spendthrift clause block cost-based termination?

No. Section 3542(h) expressly says a spendthrift or similar protective
provision does not make that section inapplicable.
