How to Choose a Trustee for a Will or Trust in England and Wales

To choose a trustee, pick people who are honest, financially capable, impartial and likely to stay well throughout the life of the trust, then decide whether a family member, a professional, or a mix of both best suits your situation. In England and Wales you can appoint up to four trustees, and at least two (or a trust corporation) are needed to hold land or release capital.

The right choice depends on the length of the trust, the value and type of assets, and your family. This guide sets out what to look for and what commonly goes wrong. Legal points and figures are current as at August 2026 and are subject to change.

What does a trustee actually do?

A trustee legally holds and manages the assets in a trust for the people who benefit from it, following the trust's terms and the law. Trustees decide on investments, make payments to beneficiaries, keep records, and must act in the beneficiaries' best interests rather than their own.

Under the Trustee Act 2000, trustees owe a statutory duty of care and must invest as a prudent person would. Understanding this helps you judge who can carry the role. Core duties include:

1. Act in good faith in the best interests of all the beneficiaries, and follow the trust deed or will.
2. Invest prudently, reviewing investments and taking advice where the trust holds significant assets.
3. Stay impartial between beneficiaries, including between those who benefit now and those who benefit later.
4. Keep proper accounts, act unanimously unless the trust says otherwise, and take no unauthorised personal profit.

What qualities should you look for in a trustee?

Look for honesty, sound judgement with money, impartiality, and the capacity and willingness to serve for the full length of the trust. A trust for young children can run 18 years or more, so age and health matter as much as good intentions. The strongest choices combine personal knowledge of your family with the discipline to keep records and take advice.

1. Integrity. The trustee holds legal control of your assets, so trustworthiness comes first.
2. Financial competence. Comfort with money and investment decisions, or the good sense to take professional advice.
3. Impartiality. Ability to treat beneficiaries fairly and stay out of family factions.
4. Capacity and age. Young and well enough to serve for what may be a long trust; avoid appointing only elderly relatives for a long-running trust.
5. Willingness. A genuine agreement to take on the work, so ask before you name anyone.
6. Availability. Time to attend to the trust, and ideally reasonable proximity to the assets and beneficiaries.

Which trustee setup fits your situation?

Match the trustee to the job. A straightforward trust for capable adults rarely needs a professional, while a trust for a vulnerable beneficiary, a blended family, or business assets usually does. The table below is a starting point, not a rule, and every trust deserves its own review.

You are not locked in. Trustees can retire and be replaced, so a setup that fits now can change as children grow up or a trust simplifies. Read our overview of how trusts work if you are still deciding whether a trust is right for you.

How many trustees should you appoint?

Most people appoint two or three trustees. You can have up to four for a trust holding land, and you usually need at least two individuals, or one trust corporation, to give a valid receipt for capital or the proceeds of selling a property. A single trustee is legally possible for some personal-property trusts, but a second provides a safeguard and continuity.

1. Minimum in practice: two individuals, so decisions are checked and the trust continues if one dies or resigns.
2. To hold or sell land: at least two trustees, or a single trust corporation, are needed to give a valid receipt (Trustee Act 1925).
3. Maximum: four trustees where the trust holds land (Trustee Act 1925, section 34).
4. Age: a trustee must be at least 18.
5. Substitutes: name replacement trustees or a power to appoint new ones, so the trust is never left short.

Can a beneficiary be a trustee?

Yes. A beneficiary can act as a trustee, and in family trusts it is common, for example a surviving spouse who is also a trustee. The issue is conflict of interest, because a beneficiary-trustee helps decide on payments they may receive. This is manageable but should be handled deliberately.

Where a beneficiary is a trustee, many families appoint an odd number of trustees or add an independent professional as a neutral voice, and record any conflict in the trust document. That keeps decisions defensible if a beneficiary later questions them.

What do people get wrong when choosing trustees?

Most trustee problems trace back to a handful of avoidable choices made when the will or trust was drafted, rather than to bad luck later on. Disputes between trustees are expensive and slow to resolve, so it is worth checking your proposed appointment against the common errors below before you sign anything.

1. Appointing relatives who do not get on. Naming two people already in conflict, such as feuding siblings, invites deadlock, because trustees generally must act unanimously.
2. Choosing only elderly trustees for a long trust. A trust for young children may outlast the people you appoint, so include a younger or professional trustee.
3. Never asking the person first. A trustee can refuse to act, which can leave the trust stuck until a replacement is found.
4. Appointing a sole trustee. One trustee cannot give a valid receipt for the sale of land, and offers no continuity if they die or lose capacity.
5. Naming a professional without checking succession. If a named solicitor retires and no firm or trust corporation stands behind them, the trust can be left without a professional trustee.
6. Ignoring conflicts. Loading the trust with beneficiaries as the only trustees, with no neutral voice, makes later decisions easy to challenge.

How do you appoint a trustee?

Trustees are named in the will or trust deed that creates the trust, and further trustees can be appointed later using the powers in that document or the Trustee Act 1925. The practical steps are straightforward once you have chosen the right people.

1. Shortlist. Decide on the mix of family and professional trustees that fits your situation and the length of the trust.
2. Ask first. Confirm each person is willing and understands the duties and the likely time commitment.
3. Name them in the document. The trustees are set out in the will or trust deed, along with any power to appoint replacements.
4. Add substitutes. Include replacement trustees or a clear power to appoint new ones, so the trust is never left short.
5. Review periodically. Revisit the choice after major life events, or when a trust simplifies or a trustee can no longer serve.
