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

If you've ever Googled "how to protect my assets for my children" or "how to avoid inheritance tax UK," you've probably landed on pages full of legal jargon, scary fee quotes, and zero practical guidance. This post changes that.

A family discretionary trust is one of the most powerful legal tools available to UK families who want to protect their wealth, plan for the future, and make sure their money ends up with the right people — not HMRC.

Here's everything you need to know, in plain English.

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.

Inheritance Tax Benefits

In the UK, assets held in a discretionary trust are generally outside your estate for inheritance tax purposes, provided the transfer is structured correctly and the settlor doesn't retain a benefit from the trust.

The standard IHT threshold is £325,000 per person (the nil-rate band). Transfers into trust that exceed this may trigger a 20% entry charge. Trusts are also subject to periodic charges every 10 years (up to 6%) and exit charges when assets leave the trust. These rules exist — but for most families the long-term IHT savings more than outweigh them.

The seven-year rule also applies: gifts made more than seven years before death fall outside the estate entirely for IHT. A well-structured trust, set up early, can be an extraordinarily effective tool for reducing your eventual inheritance tax liability.

Important update for April 2027: HMRC is simplifying IHT reporting requirements for trusts. From April 2027, many trusts that currently have to file periodic and exit charge returns will no longer need to do so if there is no tax to pay. This is a meaningful reduction in administrative burden for families with trusts within the nil-rate band — and another reason to get your trust set up before the rules change.

Protection from Creditors and Divorce Proceedings

Assets in trust are generally outside the reach of your personal creditors. If you face financial difficulty, the assets in the trust are not yours — they belong to the trust — and are far harder for creditors to reach.

The same principle applies when a beneficiary faces financial difficulty or goes through a divorce. Because no beneficiary has an automatic entitlement to trust assets, those assets don't automatically form part of a matrimonial settlement. A divorcing spouse's legal team cannot simply demand the trust pays out. The trustees retain discretion — and that discretion is protected.

This is one of the most powerful and underappreciated features of a family discretionary trust. The protection isn't just for you: it extends to your children and grandchildren too.

Generational Transfer

A discretionary trust can last up to 125 years under the Perpetuities and Accumulations Act 2009. Set it up now and it can protect your family's wealth across multiple generations — outlasting you, your children, and potentially your grandchildren.

Assets inside the trust don't go through probate on death. They continue to be held by the trustees, passing seamlessly from one generation to the next without the delay, cost, and publicity of the probate process.

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 records the true beneficial ownership. Without it, the beneficial owner has no documented evidence of their interest if the legal titleholder dies, divorces, or faces a claim.

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.
