What Is a Trustee Model? Duties, Discretion, and HEMS

A trustee model is a legal arrangement in which one person or institution — the trustee — is given independent authority to manage property or financial affairs for the benefit of someone else, the beneficiary, using their own judgment rather than following line-by-line instructions. The trustee is not a messenger carrying out the beneficiary’s wishes on request. They are a steward with real decision-making power, and that power comes bundled with legally enforceable duties that govern how every choice must be made.

The arrangement rests on a trade. The beneficiary gives up day-to-day control; the trustee accepts a standard of conduct higher than almost any other in private law. If the trustee lives up to that standard, the beneficiary gets professional, flexible management of assets through changing conditions. If the trustee doesn’t, the law gives the beneficiary tools to recover losses and remove the trustee.

The Core Idea: Independent Judgment Within Limits

What makes this a trustee model rather than a simple agency relationship is independent judgment. The trustee is empowered to evaluate situations the beneficiary may not fully understand — shifting tax rules, volatile markets, competing family needs — and to make the call they believe best serves the beneficiary’s interests. The trust instrument sets the outer boundaries of that authority. Within those boundaries, the trustee decides.

That autonomy is why the duties attached to the role are so strict. The beneficiary has handed over control precisely because they can’t supervise every decision, so the law supervises instead.

Fiduciary Duties the Trustee Owes

Fiduciary duties are the legal backbone of the model. They are not suggestions. A trustee who violates them can be held personally liable for the trust’s losses and stripped of any profit gained from the breach.

Duty of Loyalty

The duty of loyalty requires the trustee to manage the trust solely for the beneficiaries’ benefit. This is often called the “sole interest” rule, and it is widely considered the most fundamental obligation in trust law. A trustee cannot engage in self-dealing — buying trust property for personal use, for instance, or steering trust business to a company in which they hold a financial interest.

The Uniform Trust Code, adopted in some form by a majority of states, treats self-dealing transactions as presumptively improper. Even a deal that looks fair on its face can be challenged if the trustee stood on both sides. The duty also reaches conflicts of interest more broadly: a trustee who serves multiple trusts must make sure a decision that benefits one does not quietly cost another.

Duty of Prudence

The duty of prudence governs investment and asset management. Under the federal Employee Retirement Income Security Act, a fiduciary must act “with the care, skill, prudence, and diligence under the circumstances then prevailing that a prudent man acting in a like capacity and familiar with such matters would use.”1Office of the Law Revision Counsel. 29 USC 1104 – Fiduciary Duties The standard does not demand perfect returns. It demands a thoughtful, well-informed process.

Diversification is a core piece of that process. ERISA specifically requires fiduciaries to diversify plan investments to reduce the risk of large losses, unless circumstances make it clearly prudent not to.1Office of the Law Revision Counsel. 29 USC 1104 – Fiduciary Duties The Uniform Prudent Investor Act, adopted in nearly every state, reinforces the point by requiring trustees to evaluate investments in the context of the entire portfolio rather than judging any single holding in isolation. When courts review investment performance, the question is usually whether the trustee followed a sound process, not whether the picks happened to pay off.

How Much Discretion the Trustee Actually Has

Discretionary authority lets the trustee adapt without going back to the beneficiary for approval on every move. The trustee can shift allocations, time distributions, or hold back a payout when conditions warrant. If a beneficiary is scheduled to receive a distribution during a market downturn, the trustee might wait for a more favorable environment to preserve the trust’s value. The same authority covers tougher calls, like weighing competing requests from multiple beneficiaries.

The trust instrument sets the scope. It may grant broad authority or narrow it to specific purposes. Whatever the scope, the trustee has to document their reasoning. Written records of distribution requests, financial analyses, and the rationale behind each discretionary call become the trustee’s defense if a decision is later challenged.

The HEMS Standard

Many trust instruments limit discretion to distributions for a beneficiary’s health, education, maintenance, and support — the “HEMS” standard. The language comes from the federal tax code, which provides that a power limited by an “ascertainable standard relating to the health, education, support, or maintenance” of a person is not treated as a general power of appointment.2Office of the Law Revision Counsel. 26 USC 2041 – Powers of Appointment In practice, a trustee working under HEMS can approve distributions for medical bills, tuition, housing, and reasonable living expenses. Luxury purchases and speculative ventures fall outside it.

Because terms like “support” and “maintenance” are flexible on their face, the trustee’s documented reasoning carries real weight when a judgment call is questioned.

Beneficiary Rights That Balance the Model

Discretion on one side of the model is matched by enforceable rights on the other.

The Right to Be Kept Informed

Beneficiaries are entitled to regular accountings and reports covering the trust’s assets, liabilities, income, and distributions. Under the Uniform Trust Code’s reporting framework, adopted in most UTC states, a trustee must give current beneficiaries a written report at least annually, and any beneficiary can request a copy of the trust instrument. The reporting obligation does two things at once: it keeps beneficiaries informed, and it starts the clock on the statute of limitations for claims tied to the information disclosed.

Judicial Review and Removal

A beneficiary who believes the trustee is mismanaging the trust can petition a court for review. Courts generally apply an “abuse of discretion” standard to discretionary decisions, looking for bad faith, dishonesty, or choices that no reasonable person would have made in the circumstances. A judge will not second-guess a trustee just because a different call might have been better, but will step in when the trustee acts outside the granted authority or ignores the beneficiaries’ interests.

Under the Uniform Trust Code, a settlor, co-trustee, or beneficiary can ask the court to remove a trustee on several grounds:

  • A serious breach of trust.
  • Lack of cooperation among co-trustees that substantially impairs the trust’s administration.
  • Unfitness or persistent failure, where the trustee is unable or unwilling to administer the trust effectively and removal serves the beneficiaries.
  • A substantial change of circumstances that makes keeping the current trustee no longer in the beneficiaries’ interests.

What a Breach Costs the Trustee

A trustee who breaches these duties faces real exposure. Under ERISA, a fiduciary who breaches any responsibility is personally liable to restore all losses the plan suffered and must return any profits made through improper use of plan assets. Courts can also remove the fiduciary and impose other equitable relief.3Office of the Law Revision Counsel. 29 USC 1109 – Liability for Breach of Fiduciary Duty

Where a breach involves outright fraud or theft, criminal prosecution is possible. Federal wire fraud carries a maximum prison sentence of 20 years, rising to 30 years when the scheme affects a financial institution.4Office of the Law Revision Counsel. 18 USC 1343 – Fraud by Wire, Radio, or Television Theft or embezzlement of $5,000 or more from an organization receiving federal funds carries a maximum sentence of 10 years.5Office of the Law Revision Counsel. 18 USC 666 – Theft or Bribery Concerning Programs Receiving Federal Funds State criminal statutes may apply as well.

Who Can Serve as Trustee

The role can be filled by an individual or a corporate institution, and the choice shapes how the model actually runs.

An individual trustee is usually a family member, friend, or trusted advisor who knows the beneficiaries personally. Individual trustees often charge lower fees, or none at all, and bring personal insight into family dynamics. The trade-off: an individual has a limited lifespan, may lack investment or tax expertise, and carries personal liability for administrative mistakes.

A corporate trustee, typically a bank trust department or trust company, offers institutional continuity, professional investment management, and structured compliance. Corporate trustees do not retire, become incapacitated, or die, which makes succession seamless. They charge ongoing fees and may apply standardized policies that can feel impersonal. Some trust instruments appoint co-trustees — one individual and one corporate — to pair personal knowledge with professional management.

How Trustees Are Paid

Trustees are generally entitled to reasonable compensation. If the trust instrument sets a fee arrangement, that language controls. If the document is silent, most states allow compensation that is reasonable under the circumstances, weighing factors like the complexity of the work, the size of the trust, the trustee’s skill and experience, time spent, and local market rates for comparable services.

Corporate trustees typically charge an annual fee calculated as a percentage of assets under management, commonly in the 1% to 2% range per year, higher for smaller trusts and lower for very large ones. Some add transaction, distribution, or termination fees. Individual trustees who are not family members may charge hourly rates or flat annual fees. A beneficiary who believes the compensation is unreasonable can ask a court to review it.

Resignation and Succession

The role is not permanent. Under the Uniform Trust Code’s model provisions, adopted in most UTC states, a trustee may resign without court approval by giving at least 30 days’ written notice to the settlor (if living), all qualified beneficiaries, and any co-trustees. The trust instrument can modify those requirements. Resignation does not wipe out liability for actions taken while in office; past decisions remain reviewable.

Good trust drafting plans ahead. The instrument typically names a successor trustee or sets out a process for appointing one. If the document is silent and no willing successor steps forward, a court can appoint a replacement. Corporate trustees have built-in continuity because the institution keeps operating regardless of personnel changes; individual trustees should make sure the document spells out what happens if they can no longer serve.

Taxes and Personal Exposure

A trustee’s job is not only investment management. A trust with gross income of $600 or more in a tax year must file a federal income tax return on Form 1041.6Office of the Law Revision Counsel. 26 USC 6012 – Persons Required to Make Returns of Income Filing requires the trust’s own Employer Identification Number, obtained by submitting Form SS-4 to the IRS.7Internal Revenue Service. Instructions for Form SS-4 Certain grantor trusts are an exception and can use the grantor’s taxpayer identification number instead.

Tax missteps can reach the trustee personally. The IRS can assess the Trust Fund Recovery Penalty against a trustee responsible for collecting or paying certain taxes who willfully fails to do so. The penalty equals the full amount of unpaid taxes, and the IRS can pursue the trustee’s personal assets, including filing a federal tax lien or seizing property, to collect it.8Internal Revenue Service. Employment Taxes and the Trust Fund Recovery Penalty “Willfulness” here does not require bad intent. It is enough that the trustee knew about the outstanding taxes and chose to pay other creditors first.

That personal exposure, running through tax law, fiduciary law, and in serious cases criminal law, is the mechanism that keeps the trustee model honest. The trustee gets wide discretion. The law makes sure wide discretion is not the same as unchecked discretion.
