Indiana: Revocable Trust Amendment Requirements

Requirements one by one

Governing law and revocability presumption

Ind. Code § 30-4-3-1.5(a) permits amendment unless the trust terms expressly
provide that the trust is irrevocable. That default applies only to a trust
created under an instrument executed after June 30, 2005.

Indiana's electronic-trust chapter applies additional rules when the settlor
created or last amended the revocable trust by electronically signing an
electronic trust instrument.

Who may amend or restate

The settlor is the ordinary actor. Section 30-4-3-1.5(g)–(h) separately supplies
limited routes for an expressly authorized agent and a guardian acting with the
supervising court's approval. Trustee or beneficiary status alone does not
confer amendment authority.

For an electronic trust, § 30-4-1.5-3(9) expressly includes an amendment or
restatement executed under § 30-4-1.5-6 within the definition of an electronic
trust instrument. A paper restatement is a comprehensive amendment and must
satisfy the applicable paper method.

Trust method and exclusivity

For a paper trust, the settlor must comply with a method supplied by the trust.
Indiana does not reduce that requirement to substantial compliance. The
statutory alternatives remain available if the trust provides no method or if
its stated method is not expressly made exclusive.

If the trust was created or last amended electronically, compliance with its
method must also be confirmed by the settlor's electronic signature or ordinary
signature on paper under § 30-4-1.5-6(a)(1).

Alternative will or writing method

When a paper trust's method is absent or not expressly exclusive, a later will
or codicil may amend if it expressly refers to the trust or specifically devises
property that otherwise would pass under the trust. The other alternative must
be in writing and manifest clear and convincing evidence of the settlor's
intent.

For an electronic trust, the comparable fallback is a qualifying will or
codicil, a settlor-signed electronic record, or a settlor-signed paper record.
The electronic or paper record must both manifest clear and convincing intent
and specify the particular amendments.

Signature, witnesses, notary, and delivery

The paper alternative in § 30-4-3-1.5(c)(2)(B) expressly requires a writing.
The trust's method or a chosen will/codicil supplies its own execution acts;
the section states no universal witness, acknowledgment, notarization, or
trustee-delivery condition for every paper amendment.

Electronic amendment has a more specific signature architecture. A trust-
method amendment needs the settlor's electronic or paper signature, and the
statutory electronic or paper fallback likewise requires the settlor's
signature and a statement of the specific amendments. Section 30-4-1.5-3(16)
also defines a traditional paper amendment or restatement as signed by the
settlor on paper.

Capacity standard

Ind. Code § 30-4-2-10(b) makes the capacity required to amend a revocable trust
the same as the capacity of a testator required to make a will. The same
comparison covers creation, revocation, and adding property.

The separate physician-certification presumption in § 30-4-3-1.3 concerns
capacity to revoke for the trustee-duty rules. It should not replace the
express amendment-capacity formula in § 30-4-2-10(b).

Multiple settlors and contributed property

Unless the trust terms provide otherwise, community property may be amended
only by both spouses acting jointly. For property other than community
property, each settlor may amend the part attributable to that settlor's
contribution.

Section 30-4-3-1.5(b) makes those allocations default rules that the trust may
change. It states no prompt notice duty to the other settlors when fewer than
all act within their authority.

Agent, guardian, conservator, and court authority

An agent may exercise amendment powers only to the extent expressly authorized
by the trust terms or the power of attorney. Indiana uses an either-document
rule rather than requiring the express grant in both.

A guardian may act only with approval from the court supervising the
guardianship. Section 30-4-3-1.5 states no separate conservator route and does
not make guardian authority depend on an express grant in the trust.

Effective time, notice, and trustee protection

The applicable paper or electronic method determines when the required acts
are complete. Before an electronic amendment, the settlor or custodian holding
the electronic record must save a complete converted copy of the original. If
the settlor knows a custodian holds the electronic record or a complete
converted copy, the settlor must use reasonable efforts to provide that
custodian written or electronic evidence of the amendment.

The paper statute states no general beneficiary notice, co-settlor notice,
trustee receipt, or trustee acceptance condition. Under § 30-4-3-1.5(i), a
trustee without knowledge of the 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

• Using substantial compliance. Indiana says the settlor may "comply" with
  the trust method; it does not state the substantial-compliance formulation.
• Dropping the writing requirement. The ordinary nonwill fallback must be
  in writing and supported by clear and convincing evidence of intent.
• Treating all multiple-settlor trusts alike. The defaults divide authority
  by community-property status and each settlor's contribution, and the trust
  may provide otherwise.
• Using paper rules for an electronic trust. A trust created or last amended
  electronically has added signature, specificity, preservation, and custodian
  duties.

Common questions

Must an Indiana paper amendment be witnessed or notarized?

Section 30-4-3-1.5 states no universal witness or notary requirement. The
trust's own method controls when exclusive; the ordinary statutory fallback
requires a writing manifesting clear and convincing evidence of intent.

Can one settlor amend the entire trust?

Not automatically. Unless the trust changes the defaults, community property
requires joint spouses, while other property follows each settlor's
contribution.

May an agent amend if only the power of attorney grants express authority?

Yes under § 30-4-3-1.5(g). Express authority in the trust or the power of
attorney satisfies that statutory gate.
