In Minnesota a Trustee Can Rewrite an Irrevocable Trust Alone, on 60 Days' Notice, Without a Judge

“Irrevocable” is a statement about the settlor, not about the document

The word does real work: the person who created the trust gave up the power to take it back. It is routinely heard as something larger — that the terms are now fixed forever, that a drafting error is permanent, that a trust written for a family in 1998 must go on describing that family in 2040.

Minnesota law does not work that way. Minn. Stat. § 502.851 lets an authorized trustee — a defined term, and not every trustee is one — move the principal of an existing irrevocable trust into a trust with different terms. Subdivision 1(b) says the receiving trust “may be the same trust as the invaded trust with modified terms,” so a second document is not always involved. The statute calls the old one the “invaded trust” and the new one the “appointed trust.” Everyone else calls it decanting, and the metaphor is close enough: you pour the contents into a different vessel and leave the sediment.

This section was amended in 2025 (Laws 2025, ch. 15, §§ 22–28), so material written before that year may describe it inaccurately.

Who can do it

Not every trustee. Subdivision 1(c) defines an “authorized trustee” as a trustee with authority to pay principal to or for one or more current beneficiaries —

other than a trustee who is the settlor, or a beneficiary to whom income or principal must be paid currently or in the future, or who is or will become eligible to receive a distribution of income or principal in the discretion of the trustee, other than by the exercise of a power of appointment held in a nonfiduciary capacity.

So the settlor cannot decant their own trust, and neither can a trustee who stands to receive from it. In the common family arrangement where an adult child is both trustee and beneficiary, that child is not an authorized trustee for this purpose. Whether anyone can decant a given trust often comes down to who else is serving.

How much can change depends on one word

The statute splits into two tracks, and which one applies turns on whether the trustee has “unlimited discretion.” Subdivision 1(i):

“Unlimited discretion” means the unlimited power to distribute principal. A power to distribute principal that includes words such as best interests, welfare, comfort, or happiness shall not be considered a limitation of the power to distribute principal.

That second sentence matters more than it looks. Trusts are full of language like “for the beneficiary’s health, education, maintenance and support” or “as the trustee deems to be in the beneficiary’s best interests.” The statute says the second kind of phrase does not cut discretion down. A trustee who reads that language and assumes it puts them on the restricted track may be wrong about which track they are on.

With unlimited discretion, subdivision 3(a) permits appointment of part or all of the principal to a trustee of an appointed trust “for, and only for the benefit of, one, more than one, or all of the current beneficiaries of the invaded trust, to the exclusion of any one or more of the current beneficiaries.” Successor and remainder beneficiaries of the new trust must come from the old trust’s successor and remainder beneficiaries, again with exclusions permitted. Beneficiaries can be dropped.

Adding is where the statute is less closed than it first looks. Subdivision 3(a) does not let a trustee appoint principal to someone who was never a beneficiary. Subdivisions 3(b) and 3(c) do something else: the trustee may grant a current beneficiary — one who could receive principal outright under the old trust — a discretionary power of appointment in the new trust, and the class of permissible appointees under that power “may be broader or otherwise different from the current, successor, and remainder beneficiaries of the invaded trust.” Subdivision 3(d) adds that where the old trust’s beneficiaries are described by a class, the new trust’s may include “present or future members of the class.” Property can end up with people the invaded trust never named — not because the trustee appointed it to them, but because the trustee handed a beneficiary the power to.

Without unlimited discretion, subdivision 4(a) requires the current beneficiaries and the successor and remainder beneficiaries of the new trust to “be the same as” those of the old, and subdivision 4(b) requires the same distribution language to carry over. Much of what is left on this track is administrative — trustee succession, situs, investment provisions, the machinery — but not all of it. Subdivision 4(c) lets a trustee on the restricted track extend the term of the new trust beyond the term of the old one, and for that extended period include “language providing the trustee with unlimited discretion to invade the principal of the appointed trust during this extended term.” Subdivision 6 says it from the other side: the appointed trust “may have a term that is longer than the term set forth in the invaded trust, including, but not limited to, a term measured by the lifetime of a current beneficiary.” Pushing a trust past the date the settlor set for it to end, and picking up unlimited discretion over principal for the extension, are not machinery.

No consent. No court. Sixty days.

This is the part that surprises people, and it is stated plainly in subdivision 11(b):

An authorized trustee may exercise the power authorized by subdivision 3 or 4 without the consent of the settlor or the persons interested in the invaded trust and without court approval, provided that the authorized trustee may seek court approval for the exercise with notice to all persons interested in the invaded trust.

Subdivision 11(a) requires a signed, dated written instrument, and makes the exercise effective 60 days after notice is delivered, unless everyone entitled to notice agrees in writing to an earlier effective date or waives in writing the right to object.

Notice under subdivision 11(c) goes to anyone with the right, “pursuant to the terms of the invaded trust,” to remove or replace the authorized trustee; to all persons interested in the invaded trust — defined in subdivision 1(g) as all qualified beneficiaries under Minn. Stat. § 501C.0103(m); and to anyone who would be considered the owner of “all or any portion of” the appointed trust under I.R.C. §§ 671 to 679. They receive the instrument, the new trust, and the old trust.

Then subdivision 11(f) draws a distinction worth reading twice:

A person entitled to notice may object to the authorized trustee’s exercise of the power under this section by serving a written notice of objection upon the authorized trustee prior to the effective date of the exercise of the power. The failure to object shall not constitute a consent.

Silence is not agreement. What silence does buy the trustee is in 11(g): if no written objection arrives in time, the trustee “is not liable to any person who received the required notice for the exercise of the power.” Protection from liability, not approval.

If an objection does arrive, either side may petition the court, and under 11(h) “a person objecting to the proposed exercise has the burden of proof as to whether the authorized trustee’s proposed exercise should not be performed.” A person who stayed silent earlier “is not estopped from opposing the proposed exercise in the proceeding.”

The clauses that do not stop it

A power authorized by subdivision 3 or 4 may be exercised, subject to the provisions of subdivision 9, unless expressly prohibited by the terms of the governing instrument, but a general prohibition of the amendment or revocation of the invaded trust or a provision that constitutes a spendthrift clause shall not preclude the exercise of a power under subdivision 3 or 4.

The distinction is between a general prohibition and an express one. A trust that forbids amendment generally does not forbid decanting. A trust that names the power and prohibits it does — and subdivision 17 makes the same point from the other end: the section applies to any trust governed by Minnesota law “[u]nless the invaded trust expressly provides otherwise.”

That distinction is why the question “can this trust be decanted?” is answered by reading the instrument for an express prohibition rather than for boilerplate about irrevocability. Whether a given document contains one, and whether it should, is a drafting question outside what this page can assess.

What a trustee cannot do

Subdivision 15(a) is the list of prohibitions, and it is where the protections actually live:

• (1) No reducing, limiting, or modifying a beneficiary’s current right to a mandatory distribution, a mandatory annuity or unitrust interest, or a current right to withdraw a percentage of value or a specified dollar amount. There is an express carve-out, “subject to the other limitations in this section,” permitting appointment to an appointed trust that is a supplemental needs trust conforming to Minn. Stat. § 501C.1205.
• (2) “[N]otwithstanding section 501C.1008, paragraph (b),” no decreasing, indemnifying against, or exonerating a trustee’s liability “for failure to exercise reasonable care, diligence, and prudence.” A trustee cannot decant itself a liability shield. The subdivision permits reallocating fiduciary roles among trustees, advisors, and protectors, and relieving one fiduciary of liability for another’s acts as Minn. Stat. § 501C.0808 allows.
• (3) No altering or eliminating someone’s right to remove or replace the trustee, unless notice went out under 11(c) or a court approves.
• (4) No binding and conclusive fixing of any asset’s value.
• (5) No extending the new trust beyond the old trust’s permissible perpetuities period — and “any exercise of the power which extends the term of the appointed trust beyond the permissible period of the rule against perpetuities of the invaded trust shall void the entire exercise of the power.” Not the offending provision. The whole thing.
• (6) No jeopardizing tax benefits the original contribution qualified for — the gift-tax annual exclusion under I.R.C. § 2503(b), the marital deduction under § 2056(a) or § 2523(a), the charitable deduction under § 170(a), § 642(c), § 2055(a), or § 2522(a), direct-skip qualification under § 2642(c), foreign grantor trust status under § 672(f)(2)(A), or “any other specific tax benefit.”

Subdivision 15(b) adds detailed rules for trusts holding S corporation stock, where the appointed trust has to remain a permitted shareholder under I.R.C. § 1361.

Subdivision 16 closes a self-dealing door: absent a court order, the trustee cannot use decanting “to change the provisions regarding the determination of the compensation of any trustee.”

It is a fiduciary act, and it is optional

Two subdivisions bracket the whole power. Subdivision 9 imposes a fiduciary duty to exercise it “in the best interests of one or more proper objects of the exercise of the power and as a prudent person would exercise the power under the prevailing circumstances.” Favoring one branch of a family is not itself a breach — subdivision 3(a) expressly permits appointment “to the exclusion of any one or more of the current beneficiaries.” Nor does clearing the mechanical requirements end the inquiry: subdivision 9 is a separate duty, and whether a particular exercise satisfies it is a question about that exercise. Minn. Stat. § 501C.1008 limits how far an exculpatory term can insulate a trustee, and subdivision 15(a)(2) bars using a decanting to decrease or indemnify against a trustee’s liability “notwithstanding section 501C.1008, paragraph (b)” — regardless of what that paragraph would otherwise permit.

Subdivision 13 runs the other way:

Nothing in this section is intended to create or imply a duty to exercise a power to invade principal, and no inference of impropriety shall be made as a result of an authorized trustee not exercising the power conferred under subdivision 3 or 4.

A trustee who declines to decant is not thereby doing anything wrong.

What this is actually used for

Fixing scrivener’s errors. Consolidating trusts with near-identical terms. Adding trustee-removal provisions a 1990s document lacked. Modernizing investment and administrative language. Moving a beneficiary who has become disabled into a supplemental needs structure — the case subdivision 15(a)(1) singles out.

What it is not is a general-purpose rewrite. Subdivision 15(a) is the fence: a trustee cannot cut a current right to a mandatory distribution except by appointing to a supplemental needs trust, cannot extend the new trust past the old trust’s permissible perpetuities period, and cannot use a decanting to reduce their own exposure. A trustee also cannot appoint principal to someone who was not a beneficiary of the invaded trust — though subdivision 3(b) through (d) is the route by which property can still reach such a person. If what you need falls outside those lines, the route is the court-based modification statutes, not this one.
