Trustee Duties and Responsibilities: A Complete Guide

Trusts are among the most powerful tools in international wealth planning, but their effectiveness depends entirely on how they are administered. At the heart of every trust is the trustee — a person or institution that holds legal title to trust assets and manages them for the benefit of others. Being asked to serve as a trustee is an honour, but it carries obligations that many people underestimate. Understanding what those obligations entail is essential whether you are being appointed for the first time, reviewing an existing appointment, or selecting professional trustees for a family structure.

What Is a Trustee?

In legal terms, a trustee is a person who holds property on trust for the benefit of one or more beneficiaries. The trust splits legal ownership (vested in the trustee) from beneficial ownership (belonging to the beneficiaries). This separation is the defining feature of trust law and gives trusts their power in estate planning, asset protection, and tax structuring.

A trustee may be an individual — a family member, friend, or professional — or a corporate entity, such as a licensed trust company. In most cases, there are at least two trustees to provide a check on unilateral decision-making, and a minimum of two is required to give valid receipts for the proceeds of a sale of land under the Law of Property Act 1925.

Core Fiduciary Duties

The relationship between a trustee and the beneficiaries is a fiduciary one — one of the strictest relationships recognised by law. The trustee must place the interests of the beneficiaries above their own. The key duties are as follows.

Act in the best interests of beneficiaries. A trustee's overriding duty is to act in the best interests of the beneficiaries as a whole. This means prioritising the interests of beneficiaries when making investment, distribution, and administrative decisions. A trustee who acts in their own interest — or that of a third party — at the expense of the beneficiaries is in breach of their duty.

Avoid conflicts of interest. A trustee must not place themselves in a position where their personal interests conflict with their duty to the beneficiaries. If a conflict arises, the trustee must disclose it and, where appropriate, step aside from the relevant decision. Corporate trustees typically have conflicts policies and procedures to manage these situations.

Invest prudently under the standard investment criteria. The Trustee Act 2000 imposes a duty on trustees to invest trust assets in accordance with the "standard investment criteria." These require the trustee to consider the suitability of the proposed investment for the trust and the need for diversification. In practice, this means that trustees cannot concentrate all trust assets in a single asset class or leave cash sitting idle for extended periods.

Act impartially between beneficiaries. Where a trust has multiple categories of beneficiaries — for example, income beneficiaries (who receive the income generated by the trust) and remainder beneficiaries (who receive the capital eventually) — the trustee must balance the interests of both groups. A policy of investing entirely in income-producing assets may benefit income beneficiaries at the expense of capital growth for remainder beneficiaries, and vice versa.

Not to delegate improperly. Trustees may delegate certain functions — in particular, investment management — under the Trustee Act 2000, but they must do so in writing, appoint only authorised persons, and review the arrangement periodically. The overall responsibility for the trust remains with the trustee.

Keep accounts and inform beneficiaries. Trustees must maintain proper accounts of the trust fund and, in appropriate circumstances, provide information to beneficiaries. The extent of disclosure depends on the nature of the trust (a fixed trust has different obligations to a discretionary one), but wilful concealment from beneficiaries is a breach of duty.

The Trustee Act 2000

The Trustee Act 2000 is the primary statutory framework governing trustee conduct in England and Wales. Its key contributions are:

The statutory duty of care. Section 1 imposes a duty on trustees to exercise "such care and skill as is reasonable in the circumstances." This is a variable standard — a professional trustee with specialist knowledge is held to a higher standard than a lay trustee acting without remuneration. This distinction matters enormously in practice.

The power to invest. The Act gives trustees a broad general power to invest as if they were the outright owner of the trust fund (subject to the standard investment criteria). Before the Act, many trusts were restricted to a narrow list of "authorised investments" under the Trustee Investments Act 1961 — a relic that has now been superseded.

Trustee Liability

Trustees face personal liability for breaches of duty. If a trustee misapplies trust assets — through negligent investment, unauthorised dealings, or self-dealing — they may be required to make good the loss to the trust fund from their personal assets.

Indemnity from the trust fund. A trustee is entitled to be indemnified from the trust fund for costs and expenses properly incurred in administering the trust. This right of indemnity gives trustees some protection against the financial burden of trust administration.

Professional trustee liability. A professional trustee — a licensed trust company, a solicitor acting as trustee, or a private bank — is held to a higher standard than a lay trustee. Courts have consistently held that a professional who holds themselves out as having expertise in trust administration cannot rely on the defences available to an unpaid lay trustee. Professional trustees will typically carry professional indemnity insurance to address this exposure.

Offshore Trustees

Where a trust is established in a jurisdiction such as Jersey, Guernsey, or the Cayman Islands, the trustee is typically a licensed trust company regulated by the local financial services authority — the Jersey Financial Services Commission, the Guernsey Financial Services Commission, or the Cayman Islands Monetary Authority, as the case may be.

The fiduciary duties of an offshore trustee are broadly equivalent to those of an onshore trustee, though the precise legal framework varies by jurisdiction. Jersey trust law (Trust (Jersey) Law 1984, as amended) and Guernsey trust law (Trusts (Guernsey) Law 2007) both impose robust obligations on trustees, including confidentiality, good faith, and acting in the best interests of beneficiaries.

The trustee in discretionary trusts. Where the trust is discretionary — the trustee has discretion over whether and to whom to make distributions — the offshore trustee exercises significant power. They must act in accordance with the trust deed and give proper consideration to the needs of each beneficiary, but are not bound to distribute to any particular beneficiary at any particular time.

The letter or memorandum of wishes. The settlor of an offshore discretionary trust will typically provide a letter of wishes (sometimes called a memorandum of wishes) setting out their intentions regarding distributions. This document is not legally binding on the trustee, but a responsible trustee will treat it as an important statement of the settlor's intentions and will generally seek to honour it, departing from it only where good reason exists (such as changed circumstances or where following it would be contrary to the interests of the beneficiaries as a whole).

The Role of a Protector

The protector is an additional layer of oversight that is standard in offshore trust structures and increasingly used in sophisticated onshore arrangements. A protector — typically a trusted adviser or family friend — holds certain reserved powers, most commonly:

• The power to dismiss and appoint trustees.
• The power to veto or consent to distributions.
• The power to add or remove beneficiaries (in some structures).
• The power to consent to changes in the trust deed.

The protector role is powerful and should not be underestimated. A protector with the power to dismiss the trustee can effectively control who administers the trust fund, making the appointment of a sympathetic protector of great practical significance. In disputes between settlors (or their families) and offshore trustees, the protector's position is often pivotal.

It is essential that the protector does not become a de facto trustee — if the protector's consent is required for every trustee decision, HMRC and the courts may regard the structure as a "sham" in which the trustee is acting on the settlor's instructions rather than exercising independent judgment.

Trustees and Executors: An Important Distinction

Some wills appoint the same individual or firm as both executor (responsible for administering the deceased's estate) and trustee (responsible for managing any continuing trust created by the will, such as a trust for minor children or a life interest trust for a surviving spouse).

The roles are legally distinct. The executor's function is to gather the estate, pay debts and taxes, and distribute assets in accordance with the will. Once this is done, the executor's role ends. The trustee then manages any ongoing trust assets — potentially for decades — in accordance with the trust provisions in the will. Where one person holds both roles, the transition between the two is important to manage carefully, as the legal basis for holding the assets shifts at the moment of assent.

Selecting the Right Trustee

For high-net-worth families with substantial trust assets, the choice of trustee is one of the most important decisions in a wealth plan. Key considerations include:

• Experience and expertise: does the trustee understand the type of assets and structures involved?
• Jurisdiction: is the trustee properly regulated and licensed in the relevant jurisdiction?
• Independence: is the trustee genuinely independent, or subject to influence from the settlor or a single family member?
• Continuity: a corporate trustee provides continuity that individual trustees cannot — individual trustees die, move, or become incapacitated.
• Cost: professional trustee fees vary widely. Annual fees of 0.5–1.5% of trust assets are common for offshore corporate trustees.

Important Considerations

Trust law and trustee obligations are complex and vary significantly between jurisdictions. This article provides a general overview of the position under English law and common offshore jurisdictions. Nothing here constitutes legal or financial advice. Laws change and your specific circumstances will affect how the principles described apply to you. Always take professional legal and tax advice before establishing or amending a trust structure.
