How to Set Up a Family Discretionary Trust in the UK (Without a £5,000 Solicitor Bill)

If you've ever Googled "how to plan for my children" or "how trusts and inheritance tax work," you've probably landed on pages full of legal jargon, scary fee quotes, and zero practical guidance. This post gives a clearer starting point.

A family discretionary trust can be a useful legal arrangement for families who want to plan for the future and give trustees discretion over how a defined class of people may benefit. It is not an automatic tax, care-fee, creditor or probate solution.

This guide concerns trust law in England and Wales. Tax rules are UK-wide, but trust, succession and property rules differ in Scotland and Northern Ireland. It is educational information, not advice on whether a trust is suitable for you.

What Is a Family Discretionary Trust?

A discretionary trust is a legal arrangement where you (the settlor) transfer assets into a trust. Those assets are then held by trustees (usually yourself and a trusted family member or friend) for the benefit of your chosen beneficiaries - typically your children, grandchildren, or wider family. For a complete guide to how discretionary trusts work in detail, see our family discretionary trust UK guide.

What makes it discretionary is flexibility. The trustees decide:

• Who receives money from the trust
• How much they receive
• When they receive it

No beneficiary has an automatic right to the assets. That's not a weakness - it's a feature. It means the trust can adapt to circumstances that don't exist yet, like a grandchild born twenty years from now, or a beneficiary who needs protecting from themselves.

Who Controls the Trust?

The trustees control the trust. In a family setup, that's usually you as the main trustee, with a co-trustee (often a spouse, sibling, or adult child). You set the rules in the Trust Deed - the founding legal document - and your intentions are recorded in a separate Letter of Wishes, which gives trustees context and guidance without being legally binding.

This separation matters. The Trust Deed is the legal structure. The Letter of Wishes is your voice - it tells trustees what you actually wanted, even after you're gone.

Tax and estate-planning points to check

Putting assets into a discretionary trust can have IHT, CGT, income-tax and administrative consequences. A transfer into a relevant-property trust can be a chargeable lifetime transfer: an entry charge may arise, and ten-year periodic and exit charges can apply. A gift with reservation can keep an asset relevant to the settlor's estate if the settlor continues to benefit from it.

The seven-year treatment is not a shortcut or a care-fee rule. Its application to a lifetime gift depends on the type of transfer, exemptions, retained benefit and other facts. Local authorities assess deliberate deprivation of assets by reference to intention, timing and circumstances; a trust does not automatically remove a home or other asset from a care-fee assessment.

Trust income is not generally tax-free. The tax treatment depends on the trust type and income. Most trusts have a £500 tax-free amount under the current rules, subject to the relevant conditions and possible division between certain trusts; income above it can be taxed at the applicable trustee rates.

Creditors, divorce and family circumstances

Trustee discretion can be relevant when a beneficiary faces financial difficulty or relationship breakdown, because a discretionary beneficiary does not have a fixed entitlement. It does not make trust assets untouchable: courts, creditors and other decision-makers can consider the trust's terms, administration, source of funds and facts. Take specialist advice before relying on a trust for asset-protection purposes.

Generational Transfer

A discretionary trust can last up to 125 years under the Perpetuities and Accumulations Act 2009. It can provide a framework for trustee-led planning across generations, subject to its terms and applicable law.

Assets already vested in trustees may continue to be held under the trust after a death. Whether probate or other estate administration is needed for particular assets depends on ownership, title and the circumstances.

What Documents Do You Need?

At minimum, a family discretionary trust requires:

1. A Trust Deed

The core legal document establishing the trust. It names the settlor, trustees, and beneficiaries. It sets out the powers of the trustees, the purpose of the trust, and the rules under which it operates. This is the document that creates the legal structure.

2. A Letter of Wishes

Not legally binding, but arguably just as important. Your Letter of Wishes tells your trustees - in your own words - how you'd like the trust to be managed, who you had in mind when naming beneficiaries, and how you'd like them to exercise their discretion. It travels with the Trust Deed and should be updated as your circumstances change.

3. A Nominee Declaration

Where property or shares are held in someone else's name on behalf of the trust, a Nominee Declaration can record the intended beneficial ownership. It is evidence of an arrangement, not a substitute for checking that the ownership, transfer and registration steps are legally effective.

These three documents form the legal foundation of your family trust. They don't need to be drafted by a solicitor at £300 per hour. They need to be professionally prepared, accurate, and tailored to your family's situation. Once your trust is set up, you'll also need to register it with HMRC's Trust Registration Service - a mandatory step for almost all UK trusts since 2022.

Why Solicitor Quotes Can Hit £3,000–5,000

A high-street solicitor will charge for every hour of drafting, every question answered, every document reviewed. Setting up a discretionary trust from scratch - meeting, drafting, review, execution - routinely costs between £3,000 and £5,000 at specialist firms.

That cost is a barrier. Most families simply don't go ahead. They intend to, file the idea somewhere in the back of their mind, and never take action.

Frequently Asked Questions

Do I need a solicitor to set up a family trust in the UK?

You don't legally need a solicitor, but for complex arrangements involving high-value assets, it's wise to have a qualified professional review your documents before execution. The Heirs & Order™ approach gives you professionally prepared documents - you choose whether to take them to a solicitor for a final check.

Can I be a trustee of my own trust?

Yes. It's common for the settlor to also serve as a trustee. Most families appoint two trustees - often the settlor and a spouse or adult child.

What happens to the trust when I die?

The trust continues. Assets in the trust don't go through probate and aren't subject to your estate's IHT position in the same way as personally held assets. The remaining trustees continue to manage and distribute according to the Trust Deed and Letter of Wishes.

Can I change the trust after it's set up?

Discretionary trusts can be amended in limited circumstances, but major changes must be done carefully to avoid triggering tax charges. Your Trust Deed should include appropriate flexibility provisions from the start.

Your family's wealth deserves proper protection. Don't wait until it's complicated or expensive to fix.
