The trustee of a Mississippi trust holds a position of extraordinary responsibility. When a grantor creates a trust and transfers assets to a trustee, the grantor is placing confidence in that individual or institution to manage the trust property for the benefit of others — often over the course of decades. The law matches this confidence with a correspondingly stringent set of duties, codified in Mississippi's version of the Uniform Trust Code and elaborated by Mississippi courts over generations of case law.^[1]

Understanding these duties is essential not only for trustees, but also for beneficiaries who need to know what they are entitled to expect and for grantors designing trust instruments that will guide the trustee's administration.

The Duty of Loyalty

The duty of loyalty is the most fundamental of the trustee's obligations. Under Mississippi Code Annotated § 91-8-802, a trustee shall administer the trust solely in the interests of the beneficiaries. This means the trustee must put the beneficiaries' interests ahead of the trustee's own interests in every transaction involving trust property. Self-dealing — transactions between the trustee personally and the trust — is presumptively voidable, regardless of whether the transaction was fair.^[2]

The Mississippi Supreme Court reinforced the strictness of this duty in Corley v. Stewart, 276 So. 3d 1246 (Miss. 2019), holding that a trustee who engages in self-dealing bears the burden of proving the transaction was fair and in the beneficiaries' best interests. The court emphasized that the trustee's subjective good faith is not a defense — the inquiry focuses on whether the transaction was objectively fair and whether it was conducted with full disclosure to the beneficiaries.

The duty of loyalty also prohibits the trustee from competing with the trust, using trust property for personal benefit, or taking advantage of opportunities that belong to the trust. If the trustee manages a family business held in trust, the trustee may not use the business's resources for personal ventures or divert business opportunities to the trustee's own accounts.

The Duty of Impartiality

When a trust has multiple beneficiaries — as most do — the trustee has a duty to act impartially, giving due regard to the beneficiaries' respective interests. Under § 91-8-803, this means the trustee must balance the interests of current income beneficiaries against the interests of remainder beneficiaries. A trustee who invests exclusively for income at the expense of principal growth, or exclusively for growth at the expense of current income, violates the duty of impartiality.^[3]

The duty of impartiality does not require equal treatment — it requires fair treatment in light of the terms and purposes of the trust. If the trust instrument directs the trustee to prioritize the needs of the surviving spouse, the trustee may favor income production even at some cost to remainder growth. The key is that the trustee's investment and distribution decisions must be consistent with the trust instrument and made with due regard for all beneficiaries.

The Prudent Investor Rule

Mississippi has adopted the Uniform Prudent Investor Act, codified at Miss. Code Ann. § 91-9-601 et seq., which requires the trustee to invest and manage trust assets as a prudent investor would, considering the purposes, terms, distribution requirements, and other circumstances of the trust. The standard is applied to the portfolio as a whole, not to individual investments. Diversification is required unless the trustee reasonably determines that the purposes of the trust are better served without diversifying.^[4]

The prudent investor rule replaced the older, more restrictive "legal list" approach, which limited trustees to specific categories of investments. Under the modern rule, a trustee may invest in any type of property or investment strategy consistent with the applicable standard of care — including equities, alternative investments, and real estate — provided the investment decisions are made prudently and in the context of the overall portfolio.

A trustee who retains a concentrated position in a single stock — a common scenario when the trust was funded with the grantor's closely held business interests or a large block of publicly traded stock — must evaluate whether the concentration serves the trust's purposes or whether diversification is warranted. Failure to diversify a concentrated position is one of the most common bases for trustee liability in breach-of-fiduciary-duty litigation.

The Duty to Inform and Account

Trustees have an affirmative obligation to keep beneficiaries informed about the trust's administration. Under § 91-8-813, the trustee must provide qualified beneficiaries with an annual accounting of the trust's receipts, disbursements, and assets, as well as notice of any change in the trustee's compensation. Beneficiaries are entitled to inspect the trust instrument and to receive information reasonably necessary to protect their interests.

The accounting requirement serves a dual purpose: it provides transparency to the beneficiaries and creates a record of the trustee's administration that can be relied upon if questions arise later. A trustee who fails to provide regular accountings invites suspicion and may find it difficult to defend administration decisions that were never documented or communicated to the beneficiaries.^[5]

The Duty to Administer in Accordance with the Trust Terms

The trustee must administer the trust in accordance with its terms and purposes, as well as the interests of the beneficiaries. Under § 91-8-801, the terms of the trust prevail over default provisions of the UTC to the extent the terms are not contrary to public policy. This means the trust instrument is the trustee's primary guide — if the trust requires distributions for education, the trustee must make education distributions; if the trust prohibits investment in certain asset classes, the trustee must respect those restrictions.

At the same time, the trustee has a duty to exercise judgment and discretion where the trust terms grant it. A trustee with discretionary distribution authority must actually exercise that discretion — considering the beneficiary's needs, the beneficiary's other resources, and the long-term needs of all beneficiaries — rather than adopting a rigid policy of always distributing or always withholding.

Consequences of Breach

A trustee who breaches any of these duties is personally liable to the beneficiaries for the resulting damage. Remedies may include removal of the trustee, surcharge (personal liability for losses caused by the breach), disgorgement of profits from self-dealing, and an accounting of the trustee's administration. Mississippi chancery courts have broad equitable powers to fashion appropriate relief, and attorney's fees may be awarded in egregious cases.

Trustees who are uncertain about their obligations — particularly when faced with competing beneficiary interests, concentrated investment positions, or requests for unusual distributions — should seek legal counsel before acting. The cost of obtaining guidance is a legitimate trust expense, and it is far less than the cost of defending a breach-of-fiduciary-duty claim after the fact.
