Trustee Duty of Impartiality: Tools, Breaches, and Remedies

The trustee’s duty of impartiality requires a trustee who serves two or more beneficiaries to invest, manage, and distribute trust property equitably, giving due regard to each beneficiary’s interests as defined by the trust’s purposes. Equitably does not mean equally. Under Section 803 of the Uniform Trust Code, adopted in some form by most states, the trustee must treat beneficiaries fairly in light of what the settlor set out to accomplish, which often calls for deliberately unequal treatment rather than identical shares.¹

Equitable, Not Equal

The word “impartially” misleads a lot of trustees and beneficiaries. UTC Section 803 says that when a trust has two or more beneficiaries, the trustee “shall act impartially in investing, managing, and distributing the trust property, giving due regard to the beneficiaries’ respective interests.”¹ The official comment is explicit that the trustee “must treat the beneficiaries equitably in light of the purposes and terms of the trust.”

Consider a common structure: a surviving spouse named as the primary beneficiary during her lifetime, with children as remainder beneficiaries who receive what is left when she dies. The settlor clearly intended the spouse to come first. Splitting distributions evenly between the spouse and the children would ignore that intent and would itself breach the duty. Impartiality is measured against the trust’s purposes, not against a scale that reads out zero.

The duty reaches every decision the trustee makes: which investments to hold, when to sell, how much to distribute, and how to allocate receipts and expenses between income and principal. The official comment flags the last of those as a frequent trouble spot and tells trustees to be “particularly sensitive” to those allocations.¹

Where the Duty Bites: Income Versus Remainder Beneficiaries

The duty surfaces most sharply in the tension between current beneficiaries, who receive income during their lifetime or a set period, and remainder beneficiaries, who take the principal when the current interest ends. The two groups have opposing financial interests, and every investment decision helps one at the expense of the other.

Load the portfolio with high-dividend stocks and bonds and the income beneficiary gets a steady check, but long-term growth suffers and the remainder beneficiaries receive less. Tilt the portfolio toward growth stocks that pay no dividends and the principal may grow handsomely while the income beneficiary has little to live on. Neither extreme satisfies the duty. The trustee has to construct a portfolio that produces reasonable current income while also preserving and growing the principal, and should document the reasoning behind the mix so the balancing is visible.

Illiquid Assets Complicate the Balance

Concentrated or illiquid assets, such as real estate, closely held business interests, and artwork, make the balance harder. They often produce little or no income, starving the current beneficiary while the full value sits locked up for the remainder beneficiary. A trustee cannot simply sell a family business to rebalance if the trust terms require keeping it, or if a sale would destroy value.

For these trusts, the trustee weighs each asset’s role in the overall portfolio, the expected total return from both income and appreciation, the beneficiaries’ other resources, and any special value the asset holds for the trust’s purposes or for a particular beneficiary. Prudence is judged against the total portfolio, not any single holding, so an illiquid asset producing no income can still be appropriate if the rest of the portfolio compensates.

Family Business Conflicts

A particularly treacherous version of this shows up when a trust holds a family business and one beneficiary works in the business while others do not. The working beneficiary wants to reinvest profits, take a salary, and grow the company. The non-working beneficiaries want distributions. If the working beneficiary is also the trustee, the conflict sharpens because the trustee’s personal financial interest in the business clashes directly with the duty to treat the other beneficiaries fairly. Courts scrutinize these dual-role situations closely, and a trustee who consistently favors reinvestment over distributions to other beneficiaries risks surcharge or removal.

How Trust Terms Modify the Duty

The duty of impartiality is a default, not an absolute. The settlor’s intent, expressed in the trust document, controls. A trust that explicitly states the surviving spouse’s comfort takes priority over preserving principal for the children authorizes the trustee to favor the spouse, because the settlor’s instructions override the general standard of neutrality. The official comment to Section 803 makes this plain: a settlor who wants one beneficiary favored “should provide appropriate guidance in the terms of the trust.”¹

Many trust documents grant the trustee “sole and absolute discretion” over distributions. That language gives real latitude, but it is not unlimited. Under the UTC, trust terms cannot waive the requirement that the trustee act in good faith and in accordance with the trust’s purposes, and they cannot shut out court oversight. A trustee who zeroes out one beneficiary while showering another is likely to lose a challenge even with broad discretion language in the instrument. Discretion creates room for judgment calls. It does not erase a beneficiary.

Tools Trustees Use to Stay Balanced

Traditional allocation rules, which drop every trust receipt into either an “income” bucket or a “principal” bucket, generated constant friction between the two beneficiary groups. Most states have adopted tools that give trustees flexibility to invest for total return while still treating everyone fairly.

The Power to Adjust

Many states let a trustee shift funds between the income and principal accounts when the default allocation would produce an unfair result. If the trustee invests for total return and the portfolio generates mostly capital gains rather than dividends, the trustee can reallocate some gains from principal to income so the current beneficiary receives a reasonable payout. The reverse works too: if the portfolio throws off excessive income at the expense of principal growth, the trustee can redirect some income to principal.²

The Uniform Fiduciary Income and Principal Act (UFIPA) authorizes these adjustments without court approval when the trustee determines the adjustment will help administer the trust impartially. The power has guardrails. A trustee cannot exercise it if doing so would trigger adverse federal tax consequences, such as causing trust assets to be included in someone’s taxable estate, creating a deemed gift, or jeopardizing a marital deduction or generation-skipping transfer tax exemption.³

Unitrust Conversion

A more structural fix is converting the trust to a unitrust, which pays the income beneficiary a fixed percentage of total trust value each year rather than whatever dividends and interest happen to come in. The trustee can then invest purely for total return. The IRS has endorsed unitrust payout rates between 3% and 5%, and under the UFIPA, trusts that qualify for special tax benefits must stay within that range.³ The unitrust approach largely eliminates the income-versus-principal tug of war, because both groups benefit from portfolio growth: if total value rises, the income beneficiary’s payout rises automatically, and the diversified portfolio behind it serves the remainder beneficiaries too.

What Beneficiaries Are Entitled to See

Impartiality means little if beneficiaries cannot see what the trustee is doing. Under UTC Section 813, a trustee has affirmative reporting duties built into the law of most states:

Keep qualified beneficiaries reasonably informed about the administration of the trust and the material facts they need to protect their interests.
Send qualified beneficiaries at least annually a report of trust property, liabilities, receipts, disbursements, and the trustee’s compensation.
Notify qualified beneficiaries within 60 days of accepting the trusteeship and provide contact information.
On request from a qualified beneficiary, furnish a copy of the trust instrument.

These disclosures are also what starts the clock on breach claims, so they matter to both sides. State implementations vary, and some states let the settlor waive or modify certain reporting duties in the trust document.

Remedies When the Trustee Breaches

When a trustee tilts the scales unfairly, the UTC gives courts broad discretion to “order any appropriate relief.” A few remedies do most of the work.

Surcharge

A surcharge makes the trustee repay the trust from personal funds for losses caused by the breach. Courts measure the amount by comparing where the trust stands with where it would stand had the trustee acted properly, which can include direct losses, lost appreciation or income, interest that would have accrued, and improperly paid fees. The goal is corrective rather than punitive: restore the trust to its proper position.

Equitable Adjustments

Not every imbalance has to come out of the trustee’s pocket. Courts (and trustees themselves) can use equitable adjustments to shift funds between the income and principal accounts to correct a past imbalance. If the trustee invested too aggressively in growth assets and the income beneficiary was shortchanged for years, a court can direct that a portion of principal gains be reclassified as income. The reverse adjustment runs when the portfolio tilted too heavily toward income at the expense of principal.² This mechanism can make the disadvantaged party whole without penalizing a trustee for what may have been a good-faith misjudgment.

Trustee Removal

When the breach is serious or the trustee has shown a persistent pattern of favoritism, the court can remove the trustee and appoint a successor. Under the UTC, removal is appropriate when it serves the beneficiaries’ interests and a suitable replacement is available. Grounds include a serious breach of trust, failure to administer the trust effectively due to unfitness or persistent failures, and substantial changed circumstances.¹

Other Relief

Courts can also compel the trustee to perform specific duties, enjoin a biased investment strategy or distribution plan, void a transaction, impose a constructive trust or lien on trust property, reduce or deny the trustee’s compensation, or order a full accounting. In judicial proceedings involving trust administration, the court may award costs and reasonable attorney fees to any party, paid either by another party or from the trust itself. These remedies combine: a court might surcharge the trustee for past losses, cut future compensation, and order a revised investment strategy going forward in the same ruling.

How Long You Have to Act

Beneficiaries who suspect a breach of the duty of impartiality cannot wait indefinitely. Under the UTC model used in most states, a beneficiary generally has one year after receiving an adequate trustee report to bring a claim. A report is adequate if it provides enough information that the beneficiary knows, or should have known, about the potential problem, and if it informs the beneficiary of the time allowed for starting a proceeding.

If the trustee never sends an adequate report, the one-year clock may not start at all. States then impose a backup deadline, often three years, that runs from the trustee’s removal, resignation, or death, the termination of the beneficiary’s interest, or the termination of the trust. These deadlines vary by state, so a beneficiary who suspects bias should consult local counsel promptly rather than assume the window stays open.

Reporting duties and the limitations period work together. A trustee who sends thorough, transparent annual reports earns a relatively short window for challenges. A trustee who sends vague or incomplete reports gets no such protection. For beneficiaries, the practical takeaway is just as direct: read the reports carefully and raise concerns quickly, because the clock may already be running.
