Wisconsin: Revocable Trust Amendment Requirements

Requirements one by one

Governing law and revocability presumption

Wis. Stat. § 701.0602(1) creates a rebuttable presumption that the settlor may
amend unless the trust terms expressly provide that the trust is irrevocable.
The statute does not make the default conclusive; the instrument and evidence
can still rebut it.

The subsection excludes a trust created under an instrument executed before
July 1, 2014. That cutoff removes the statutory presumption for the older
instrument; it does not itself declare the trust irrevocable.

Who may amend or restate

The settlor is the ordinary actor under § 701.0602. Subsections (5) and (6)
separately permit a properly authorized agent or a court-approved guardian of
the estate or conservator to exercise the settlor's amendment power. Trustee or
beneficiary status alone does not confer that power.

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

Trust method and exclusivity

Section 701.0602(3) permits "substantial compliance with a method provided in
the terms of the trust." If the trust supplies a method, that is the statutory
route.

Wisconsin's alternatives turn on absence, not exclusivity. The later-will and
clear-and-convincing-intent routes become available only "if the terms of the
trust do not provide a method." A stated method does not have to say it is
exclusive to block those alternatives.

Alternative will or intent method

When the trust provides no amendment method, subsection (3)(am) recognizes a
later will or codicil that expressly refers to the trust or specifically
devises property that otherwise would pass under the trust. Subsection (3)(bm)
also recognizes any other method manifesting clear and convincing evidence of
the settlor's intent.

The reference-or-specific-devise requirement belongs to the will route. The
clear-and-convincing standard belongs to the separately listed other-method
route.

Signature, witnesses, notary, and delivery

The trust's own method controls when one exists. If none exists, § 701.0602(3)
offers the qualifying later-will route and the other-method intent route.

The section states no universal amendment-specific writing, signature,
witness, acknowledgment, notarization, trustee-delivery, or trustee-acceptance
requirement. A particular trust method can still require one or more of those
acts, and failing that method can defeat the amendment.

Capacity standard

Wis. Stat. § 701.0601 makes the capacity required to amend a revocable trust
"the same as that required to make a will." The same comparison covers
creation, revocation, adding property, and directing the trustee.

Multiple settlors and contributed property

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

When fewer than all settlors act within that allocation, the trustee must
promptly notify the others. The notice duty follows the amendment; it does not
replace the joint-action rule for marital or community property.

Agent, guardian, conservator, and court authority

An agent may exercise amendment powers only to the extent the power of attorney
expressly authorizes them. Section 701.0602(5) does not state a second express-
authority requirement in the trust instrument.

A guardian of the estate or conservator may act only with approval from the
court supervising the guardianship or conservatorship. The statute does not
grant the same route merely because someone serves as another kind of guardian.

Effective time, notice, and trustee protection

The applicable trust method or no-method alternative determines when its
required acts are complete. Section 701.0602 does not impose a 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 who does not know of an amendment is not liable
for distributions and other actions taken on the assumption that the old terms
remain in force. That protection addresses the trustee's liability; it does not
make knowledge a universal validity condition for the amendment.

What trips people up

• Treating a nonexclusive trust method as optional. Wisconsin reserves its
  will and intent alternatives for a trust that provides no method at all.
• Using one spouse's revocation power as amendment power. Either spouse may
  revoke marital or community property alone, but amendment requires joint
  action.
• Giving an agent implied authority. The power of attorney must expressly
  authorize exercise of the amendment power.
• Reading the 2014 cutoff as an invalidity rule. It removes the statutory
  presumption for the older instrument; it does not itself decide whether that
  trust is amendable.

Common questions

May an expressly authorized agent amend while the settlor still has capacity?

Section 701.0602(5) does not condition the agent's authority on the settlor's
incapacity. The agent may exercise the power to the extent the power of attorney
expressly authorizes it, subject to the trust's controlling amendment method.

Does the trustee safe harbor postpone the amendment until the trustee learns of it?

Not as a universal rule. Subsection (7) protects a trustee that acts without
knowledge; the applicable trust method or statutory no-method alternative
still determines whether the settlor completed the amendment.
