Every beneficiary who calls me opens with the same sentence: the account went down. Every trustee answers with the mirror image: the account went up. Under Minnesota law both statements are nearly beside the point, and I say so in the first five minutes.
Minn. Stat. § 501C.0901, subd. 6 puts it in one sentence:
Compliance with the prudent investor rule is determined in light of the facts and circumstances existing at the time of a trustee’s decision or action and not by hindsight. The prudent investor rule is a test of conduct and not of resulting performance.
That sentence disposes of most Minnesota trust investment disputes before anyone opens a statement. A trustee who built a written strategy, weighed the statutory factors, diversified or documented why not, and reviewed the portfolio on a schedule is defensible after a brutal year. A trustee who inherited the settlor’s concentrated position in one company and simply let it ride is exposed even if the stock tripled — because subdivision 4 imposed a duty untethered to performance, and he never performed it.
Cite § 501C.0901; chapter 501B is repealed law
The Minnesota Prudent Investor Act is Minn. Stat. § 501C.0901, titled “Investment and Management of Trust Assets.” It is the only section under the “Prudent Investor Act” heading in chapter 501C, and subdivision 12 says so: “This section may be cited as the ‘Minnesota Prudent Investor Act.’”
The Act used to live at Minn. Stat. § 501B.151. That section — with essentially all the general trust provisions of chapter 501B — was repealed by 2015 Minn. Laws ch. 5, art. 16, § 2 and recodified into chapter 501C. Chapter 501B now reads “Charitable Trusts,” and its table of sections shows most of the old numbers marked “MS 2014 [Repealed, 2015 c 5 art 16 s 2].” Section 501C.0901 was enacted in the same 2015 act (2015 Minn. Laws ch. 5, art. 9, § 1) and has not been amended since.
Trust instruments, trustee-liability policies, and briefs still cite § 501B.151 to me. A document that does is at minimum ten years stale, and that tells me something useful about the document.
Prudence is a portfolio question, and the bar rises with the trustee
Subdivision 2(a) sets the standard:
A trustee shall invest and manage trust assets as a prudent investor would, by considering the purposes, terms, distribution requirements, and other circumstances of the trust. In satisfying this standard, the trustee shall exercise reasonable care, skill, and caution.
Subdivision 2(b) then supplies the framing that changes how the claim gets proved:
A trustee’s investment and management decisions respecting individual assets must be evaluated not in isolation but in the context of the trust portfolio as a whole and as a part of an overall investment strategy having risk and return objectives reasonably suited to the trust.
That is the portfolio rule, and it governs proof as much as conduct. A beneficiary cannot build a case out of the one holding that lost money. A trustee cannot escape one by pointing at the holding that made money. Both are asking a court to evaluate an individual asset in isolation, which is precisely what subdivision 2(b) forbids.
Subdivision 2(c) lists eight circumstances a trustee may consider “without limitation,” ending with clause (8): an asset’s “special relationship or special value, if any, to the purposes of the trust or to one or more of the beneficiaries if consistent with the trustee’s duty of impartiality.”
That closing proviso carries more weight than its length suggests. Clause (8) is the statutory hook for keeping the family cabin, the farm, or the closely held shares — expressly conditioned on impartiality, and Minn. Stat. § 501C.0803 requires a trustee serving two or more beneficiaries to “administer the trust impartially, giving due regard to the beneficiaries’ respective interests.” A trustee holding an illiquid family asset because one beneficiary wants it, at the cost of another beneficiary’s income, has used clause (8) in exactly the manner the proviso prohibits.
No category of investment is forbidden — subdivision 2(d): “A trustee may invest in any kind of property or type of investment consistent with the standards of this section.” And subdivision 2(e) raises the bar for the professional: “A trustee who has special skills or expertise, or is named trustee in reliance upon the trustee’s representation that the trustee has special skills or expertise, has a duty to use those special skills or expertise.” A bank trust department and a brother-in-law answer to different standards, and the brother-in-law who told the settlor he was a sophisticated investor answers to the standard he claimed for himself.
Diversify, or make a determination you can defend
Subdivision 3, in full:
A trustee shall diversify the investments of the trust unless the trustee reasonably determines that, because of special circumstances, the purposes of the trust are better served without diversifying.
Take the exception element by element. First, the trustee must actually determine something — not drift, not inherit, not fail to act. A determination is an event with a date. Second, the determination must be reasonable, and it is tested objectively. Third, there must be “special circumstances” — not general reluctance, not tax cost raised as an afterthought, not sentiment. Fourth, the conclusion must be that the purposes of the trust are better served by not diversifying. The trust’s purposes. Not the trustee’s convenience, and not one beneficiary’s preference.
Real examples exist. A trust whose stated purpose is to hold and operate a family farm. A trust holding voting shares in an operating business where selling surrenders control the settlor plainly meant to preserve. A concentrated low-basis position where a documented analysis of embedded tax cost against concentration risk, weighed against the trust’s actual distribution needs and time horizon, comes out on the side of holding. Each is defensible. Each requires the analysis, in writing, at the time.
The failure mode I litigate is never aggressive investing. It is inertia. A trustee who never diversified because nobody asked him to has not made a reasonable determination based on special circumstances. He has made no determination at all, and subdivision 3 is breached no matter what the market did afterward.
Subdivisions 4 and 8 together: the duty almost nobody performs
Subdivision 4 is the most-breached provision in the section:
Within a reasonable time after accepting a trusteeship or receiving trust assets, a trustee shall review the trust assets and make and implement decisions concerning the retention and disposition of assets, in order to bring the trust portfolio into compliance with the purposes, terms, distribution requirements, and other circumstances of the trust, and with the requirements of this section.
Watch the verbs: review, make, implement. Not “consider.” Not “be aware of.” The duty attaches on accepting the trusteeship or receiving the assets, and the “reasonable time” clock starts running at that instant.
Now set subdivision 4 beside subdivision 8, which is where trustees talk themselves into trouble:
Unless the trust instrument or a court order specifically directs otherwise, a trustee need not dispose of any property . . . or any kind of investment, in the trust, however acquired, until the trustee determines in the exercise of a sound discretion that it is advisable to dispose of the property. Nothing in this subdivision excuses the trustee from the duty to exercise discretion at reasonable intervals and to determine at those intervals the advisability of retaining or disposing of property.
Trustees read subdivision 8 as permission to hold. It is nothing of the kind. It is permission to decide to hold, and its second sentence imposes an affirmative, recurring duty to exercise discretion at reasonable intervals and make that decision over again. Read the two subdivisions together and the obligation is plain: on day one, review everything you received and implement decisions; at reasonable intervals thereafter, decide again whether to keep each holding; and at no point simply leave an asset alone because the settlor bought it.
“However acquired” in subdivision 8 is deliberate drafting. It reaches assets the settlor contributed. The settlor’s purchase decision has never been the trustee’s defense.
Subdivision 5 adds cost discipline: “In investing and managing trust assets, a trustee may only incur costs that are appropriate and reasonable in relation to the assets, the purposes of the trust, and the skills of the trustee.” Layered fees — a trustee fee, plus a manager fee, plus fund-level expenses, all on the same dollars — get measured against that sentence.
The rule is waivable. Good faith is not.
The prudent investor rule yields to the instrument more completely than most of the Trust Code. Subdivision 1:
(a) Except as otherwise provided in paragraph (b), a trustee who invests and manages trust assets shall comply with the prudent investor rule set forth in this section.
(b) The prudent investor rule, a default rule, may be expanded, restricted, eliminated, or otherwise altered by the trust instrument. A trustee is not liable to a beneficiary to the extent that the trustee acted in reasonable reliance on the trust instrument.
“Eliminated” is a strong word, and it is the legislature’s own. A settlor may direct retention of a specific asset, waive diversification by name, or displace the rule altogether, and a trustee who reasonably relies on that direction is protected to that extent.
The elimination stops short of total, because § 501C.0901 sits inside a code with mandatory floors. Under Minn. Stat. § 501C.0105(b), the terms of a trust prevail over the chapter except as to, among other things, “the duty of a trustee to act in good faith and in accordance with the terms and purposes of the trust and the interests of the beneficiaries” (clause (2)), “the requirement that a trust and its terms be for the benefit of its beneficiaries, and that the trust have a purpose that is lawful, not contrary to public policy, and possible to achieve” (clause (3)), and “the effect of an exculpatory term under section 501C.1008” (clause (8)). Section 501C.1008(a)(1) then makes exculpation unenforceable to the extent it relieves a trustee of liability for a breach committed “in bad faith or with reckless indifference to the purposes of the trust or the interests of the beneficiaries.”
So the honest statement of Minnesota law is short: the prudent investor rule is waivable; good faith is not. A retention direction protects the trustee who holds the asset and keeps thinking. It does nothing for the trustee who holds the asset, watches it collapse, and does nothing while a beneficiary goes without.
Two further limits are worth carrying. Subdivision 9 preserves the court’s power — the section “does not restrict the power of a court of proper jurisdiction to permit a trustee to deviate from the terms of a will, agreement, court order, or other instrument” relating to investment or retention of trust property, which is the escape valve when a mandatory retention clause turns destructive. And subdivision 7 provides that older formulations in an instrument — “legal investments,” “authorized investments,” “prudent man rule,” “prudent person rule,” and the long “judgment and care under the circumstances then prevailing” clause — all authorize any investment or strategy permitted under the modern section, “unless otherwise limited or modified.” A 1974 trust does not trap its trustee in 1974 investment law.
Total return starts the income-versus-remainder fight; § 501C.1112 ends it
Once a trustee invests for total return rather than yield, the traditional split between “income” for the current beneficiary and “principal” for the remainder stops tracking economic reality. Minnesota’s answer is Minn. Stat. § 501C.1112, the trustee’s power to adjust between principal and income. Subdivision 1 conditions that power on the very thing this article is about: the trustee may adjust “if the trustee invests and manages the trust assets as a prudent investor and the terms of the trust describe the amount that may or must be distributed to a beneficiary by referring to the trust’s income.” Subdivision 2 lists the factors — the trust’s nature, purpose, and expected duration; the settlor’s intent; the beneficiaries’ circumstances; and whether an asset “was purchased by the trustee or received from the settlor.”
The practical upshot: a trustee holding a growth portfolio and telling the income beneficiary there is nothing to distribute because the portfolio yields little may have a § 501C.1112 problem stacked on a § 501C.0803 impartiality problem. The power to adjust exists so that prudent total-return investing does not quietly disinherit the current beneficiary.
The file I want to see
Nothing here is fancy. It is evidence that decisions were made.
- An investment policy statement tied to this trust’s purposes, terms, distribution requirements, time horizon, and beneficiaries — the subdivision 2(a) and 2(b) factors, in writing.
- A dated day-one inventory and review memo recording what was received and what was decided about each holding, satisfying subdivision 4’s “review . . . make and implement.”
- A diversification memo wherever the portfolio is concentrated: the special circumstances, the analysis, and the conclusion that the trust’s purposes are better served without diversifying — subdivision 3.
- Periodic review minutes on a stated interval, each recording the decision to retain or dispose — subdivision 8’s second sentence.
- A fee analysis showing why the total cost stack is appropriate and reasonable — subdivision 5.
- Delegation documentation if an outside manager is used. A trustee may delegate under Minn. Stat. § 501C.0807, but must use reasonable care in selecting the agent, setting the scope and terms, and “periodically reviewing the agent’s actions in order to monitor the agent’s performance and that the agent is acting in compliance with the terms of the delegation.” Hiring a manager does not end the duty; it swaps one duty for another. (Direction is a different structure again — see directed trusts and trust protectors.)
- Impartiality notes where beneficiaries’ interests diverge — § 501C.0803 — and adjustment analysis under § 501C.1112 where they diverge over income.
For a beneficiary, that list is the document request, verbatim. When none of it exists, the trustee’s defense will consist of performance numbers, and subdivision 6 says performance is not the test.
Two things a bad year does not decide
Losses alone are not a claim. Minn. Stat. § 501C.1003(b): “Absent a breach of trust, a trustee is not liable for a loss or depreciation in the value of trust property or for not having made a profit.” A down market by itself is not a case, and I will tell a prospective client that on the first call.
Nor does a grievance keep indefinitely. A claim against a trustee is governed by Minn. Stat. § 501C.1005 — three years from a report that adequately disclosed the potential claim, six years otherwise — and those periods cannot be varied by the trust instrument. If a trustee has been mailing you statements about a concentrated position for years, the clock has been running the whole time. That analysis is here. If the concern is not how the trustee invests but who the trustee is, decanting and the comparison to South Dakota-style structures are the neighboring questions.
Madgett Law, LLC evaluates Minnesota trust investment claims from the file rather than the account balance — whether a day-one review under § 501C.0901, subd. 4 ever happened, whether a diversification determination under subd. 3 was ever made or merely assumed, and whether periodic review under subd. 8 exists as anything beyond a statement in the mail. We represent beneficiaries pursuing those claims and trustees defending them. If you are a trustee sitting on a concentrated position you did not choose, get the analysis done and dated now. If you are a beneficiary watching one, the documents you need belong to the trustee, and there is a deadline. Call 612-470-6529 or send us a message.
