How to Choose a Trustee: A Practical Guide for England and Wales

To choose a trustee, pick someone who is honest, financially responsible, well organised and likely to be around for as long as the trust lasts, and who understands the duties involved. Many people appoint a trusted individual alongside a professional, and name at least two trustees so the trust can keep working if one can no longer act.

A trustee is the person, or company, you put in charge of assets held in a trust, whether that trust is created in your lifetime or through your will. Because trustees are the legal owners of those assets and make decisions for the people who benefit from them, the choice matters as much as the trust wording itself (gov.uk, trusts and trustees, as at August 2026, subject to change). This guide sets out what the role involves and how to choose people who can carry it well. It is part of wider estate planning, and the figures below are current as at August 2026 and subject to change.

What does a trustee actually do?

A trustee looks after the assets in a trust and uses them for the beneficiaries, following the terms of the trust deed or will and the general law. Trustees are the legal owners of the assets, they manage the trust day to day, decide how to invest or use what it holds, keep records, and pay any tax due (gov.uk, as at August 2026, subject to change). The role can last for many years, so it is as much a long-term responsibility as a one-off appointment.

• Safeguard the assets. Hold and protect the trust property, keeping it separate from their own money.
• Follow the terms. Act within the trust deed or will and treat beneficiaries even-handedly.
• Make decisions. Invest sensibly and decide, where the trust allows, how much a beneficiary receives and when.
• Keep it lawful. Maintain accounts, meet reporting duties and pay any tax the trust owes.

Qualities to look for in a trustee

Choosing a trustee is mostly about character and reliability rather than technical knowledge, which can be bought in. The right person is someone you trust completely to act in others' interests over a long period, who is organised enough to keep records and meet deadlines, and level-headed enough to handle family tensions fairly. Consider these factors together rather than any single one.

Who can you appoint as a trustee?

You can appoint a trusted individual, a professional, a trust corporation, or a combination. Anyone you appoint should generally be an adult of sound mind, and it is sensible to ask them first. Each option has trade-offs between cost, expertise and personal knowledge of your family.

A common approach is to pair someone who knows the family with a professional who knows the rules. A beneficiary can act as a trustee, but because they may face a conflict between their own interest and their duty to others, many people balance that with a second, independent trustee. If you are also writing a will, the same thinking applies when you choose executors and trustees in your will.

How many trustees should you have?

There must always be at least one trustee, but for most family trusts two to four works best. At least two matters where the trust holds land or property, because a sole trustee, other than a trust corporation, cannot give a valid receipt for capital money arising from land, so a buyer would usually need a second trustee to complete a sale (Trustee Act 1925, s.14, legislation.gov.uk, as at August 2026, subject to change). At the other end, the number of trustees of a trust of land cannot exceed four (Trustee Act 1925, s.34, legislation.gov.uk, as at August 2026, subject to change).

Trustee or executor: what is the difference?

People often mix up the two roles, and the same person is frequently appointed to both, but they are not identical. An executor gathers in your estate, pays debts and taxes and distributes what is left after death, a job that is usually finished within a year or two. A trustee holds and manages assets in a trust, which can continue for many years afterwards, for example a trust for young children until they reach an age you set. The probate process is where an executor's work sits, while a trustee's work often begins once assets pass into the trust.

The law sets a standard of care for trustees. Under the Trustee Act 2000 a trustee must exercise such care and skill as is reasonable in the circumstances, and where someone acts in the course of a business or profession, or has special knowledge, more is expected of them (Trustee Act 2000, s.1, legislation.gov.uk, as at August 2026, subject to change). That is one reason a professional trustee is held to a higher bar than a family member acting in good faith.

Most trusts must also be registered with HM Revenue and Customs through the Trust Registration Service, and this falls to the trustees. A trust set up on or after 6 April 2021 generally has to be registered within 90 days of being created or becoming liable to tax, whichever is later, and a failure to register can attract a penalty of up to £5,000 (gov.uk, register a trust as a trustee, as at August 2026, subject to change). Choosing someone organised enough to keep on top of duties like this is part of choosing well.

Common mistakes when choosing a trustee

A few avoidable errors come up again and again. Being aware of them at the outset tends to save difficulty later.

• Appointing only one trustee. A sole trustee can leave a trust stuck if they fall ill or die, and cannot alone give a valid receipt for capital money from land.
• Naming someone without asking. The role is a real commitment, and a surprised trustee may decline or struggle.
• Ignoring age and health. A trust for young children may run for decades, longer than an elderly trustee can serve.
• Overlooking conflicts. A beneficiary as sole trustee can face a clash between their own interest and their duties to others.
• Never reviewing the choice. Relationships and circumstances change, so it is worth revisiting who you have named.

Choosing trustees sits alongside other decisions about who acts for you, such as who you appoint under a lasting power of attorney. Where a trust is being used partly for inheritance tax planning, the trustees' decisions can have tax consequences, so competence and good records matter all the more.

Choosing a trustee in Scotland and Northern Ireland

This guide describes the law of England and Wales. Trust law differs across the UK. Scotland has its own rules on trusts and trustees under Scottish legislation, and some of the specific provisions cited here, such as the four-trustee limit for trusts of land, are features of the law of England and Wales rather than Scots law. Northern Ireland has a separate but broadly similar system. If a trust or its assets touch more than one jurisdiction, it can be worth taking advice in each.
