Trustee

Legal Law and EnforcementUpdated 05 Nov 2026

A trustee is a person or institution that holds legal title to property and manages it for the benefit of other people, the beneficiaries, under the terms of a trust. Trustees are found in family wealth planning, charities, pension schemes, bond issues, bankruptcies and investment funds. Whatever the setting, a trustee must act in the beneficiaries' interest rather than its own.

The trust is a creation of English law that spread to the United States and other common-law countries, and many civil-law countries now recognise it or use similar structures. A trust has three roles: the settlor who creates it and transfers property into it, the trustee who controls the property, and the beneficiaries who are entitled to the benefit. The trustee's obligations are fiduciary, which means the law holds it to the highest standard of loyalty and care. Money held this way usually sits in a trust account separate from the trustee's own funds.

01

A trustee in plain terms

A trustee is like a guardian holding the keys to someone else's house. The guardian can open the door, pay the bills and arrange repairs, and on paper the house may even be in the guardian's name. But the guardian may not live there, rent it out for personal profit or let it fall apart, because the house is being looked after for someone else.

If the guardian breaks those rules, the owner, here the beneficiary, can take the guardian to court and make them repay any loss. That legal pressure is what lets people trust strangers, banks and companies with large sums for long periods.

Duties of a trustee

Trust law in different countries uses different wording, but the core duties are similar:

  • Duty of loyalty. The trustee must act solely in the beneficiaries' interest and avoid conflicts, such as buying trust property for itself.
  • Duty of prudence. The trustee must manage and invest with reasonable care, skill and caution. In the US, the Uniform Prudent Investor Act (1994) requires trustees to judge investments as part of an overall portfolio and generally to apply diversification; England and Wales impose similar duties under the Trustee Act 2000.
  • Duty of impartiality. Where there are several beneficiaries, for example one entitled to income and another to capital, the trustee must treat them fairly.
  • Duty to keep property separate. Trust assets must be kept apart from the trustee's own and clearly identified, a principle echoed in the segregation of funds rules for payment firms.
  • Duty to account and inform. The trustee must keep records and report to beneficiaries.

Most US states have adopted some version of the Uniform Trust Code (2000), which sets these rules out in statute. Trustees may delegate tasks, such as hiring an investment adviser, but remain responsible for choosing and monitoring the delegate.

Types of trustee

  • Private and family trustees. Individuals or professional firms managing trusts for families, often alongside a family office, to pass on generational wealth.
  • Corporate trustees. Trust companies and the trust departments of banks, which act for many trusts and are licensed and supervised by banking regulators.
  • Bond (indenture) trustees. A bank appointed to act for all holders of a bond issue. In the US, the Trust Indenture Act of 1939 requires a qualified, independent trustee for most publicly offered debt; the trustee monitors the issuer and, after a default, can enforce the bondholders' rights.
  • Pension trustees. Trustees of occupational pension funds, common in the UK; in the US, plan trustees are fiduciaries under the Employee Retirement Income Security Act of 1974 (ERISA).
  • Bankruptcy trustees. Officials who take control of a debtor's assets in liquidation and distribute them to creditors.
  • Fund trustees. In the US, members of a fund board of trustees who oversee a mutual fund organised as a trust; in the UK, the trustee of an authorised unit trust, usually a bank, which holds the assets and supervises the manager, much like a fund custodian or EU depositary.

Trustees in finance and compliance

Trust structures appear throughout financial services. An escrow agent holding money until conditions are met acts in a trustee-like way. Securitisations often place assets in a trust or special purpose vehicle (SPV) with a trustee acting for investors. Some stablecoin issuers and payment firms hold customer money in trust so it is protected if the firm fails.

Trusts also attract scrutiny under anti-money laundering (AML) rules, because they can hide who really owns assets. FATF standards and many national laws require trustees to identify the settlor, trustees, beneficiaries and any ultimate beneficial owner (UBO), and banks apply enhanced know your customer (KYC) checks to trust accounts.

05

Limitations and risks

A trustee's duties are only as strong as the beneficiaries' ability to enforce them, which can be weak when beneficiaries are young, numerous or unaware of the trust. Trust deeds may include exemption clauses that limit the trustee's liability for negligence. Bond trustees often act only when instructed and indemnified by holders, so they may be slow to respond to early warning signs. And professional trustee fees can erode the value of small trusts.
