If you’re thinking about setting up a family trust fund, you’re probably hoping to safeguard your family’s assets and make sure money is passed on in a way that’s fair, practical, and secure. Trusts can seem complicated, but with a clear plan and a few straightforward steps, you can create a structure that genuinely supports your loved ones—now and in the future. This guide is for regular British families, not legal experts, and aims to make the process feel achievable and relevant.

Why set up a family trust fund?

A family trust fund is a legal arrangement where you (the settlor) transfer assets to trustees, who manage those assets for the benefit of your chosen beneficiaries. The trust deed sets out the rules, and the trustees must follow them. Family trusts are especially useful if you want to:

• Protect family wealth from impulsive spending, divorce, or creditors.

• Provide for children, grandchildren, or vulnerable relatives in stages, rather than a lump sum.

• Manage complex family situations, such as second marriages, blended families, or dependents with additional needs.

• Ensure assets are used for specific purposes, like education, housing, or health costs.

Common trust types for families:

• Discretionary trust: Trustees have flexibility to decide who gets what, when, and how much, within your guidance. This is ideal for families with changing needs or where you want to protect assets from outside claims.

• Interest in possession trust: Someone (often a spouse or partner) gets income from the assets now, with the capital passing to someone else (often children) later.

• Bare trust: The beneficiary owns the assets outright and can demand them at 18. Good for straightforward gifts, but less control over timing and use.

Step-by-step: setting up a family trust fund

1. Define your purpose and priorities

Start by writing down, in your own words, why you want the trust and what you hope it will achieve. For example:
“Support my children’s education and first homes, provide for my partner’s living costs, and protect the family home from outside claims.”
This clarity will guide every later decision and help trustees understand your intentions.

2. Choose trustees you trust

Pick two or three people who are practical, organised, and able to work together. You can also appoint a professional trustee, but this adds cost. Trustees should understand what’s expected, how decisions are made, and how to keep records.
Tip: Have an honest chat with your chosen trustees before you commit. Make sure they’re willing and understand the responsibility.

3. Draft a clear trust deed and letter of wishes

The trust deed is the legal document that sets out the rules: who the beneficiaries are, what powers the trustees have, how and when money can be used, and how trustees can be replaced.
Keep it readable and straightforward. Add a “letter of wishes” in plain English to guide trustees on judgement calls. For example, you might say, “Prioritise education and housing costs, but consider health needs if they arise.”

4. Open a trust bank or investment account

The trust will need its own account. For cash, a trustee bank account works. For longer-term trusts, consider a diversified investment account in the trustees’ names as trustees of the trust.
Providers will ask for the trust deed, so keep it handy.
Example: If you’re setting up a fund to help with first homes, you might open an investment account to grow the fund over time, then release money for deposits when needed.

5. Transfer the assets in

Move the cash, investments, or property into the trust account. For property or shares, you’ll need to complete transfer paperwork and may need help to avoid unexpected tax or charges.
Watch out: Transferring property can trigger stamp duty or capital gains tax, so check before you act.

6. Keep simple records

Keep copies of the trust deed, letters of wishes, bank statements, and trustee meeting notes. Record any distributions and the reason for them.
Annual summaries make filling out forms like R185 (trust income) much easier later.
Tip: Set up a shared digital folder for trustees to keep everything organised.

Real-life examples

• Blended family: You leave your partner an income for life from a rental property via an interest in possession trust, with the capital passing to your children later. The deed spells out maintenance obligations and priorities.

• Education and first homes: Trustees pay for school fees, university costs, and help with first-home deposits for each child, releasing funds at sensible milestones.

• Vulnerable relatives: A discretionary trust provides regular support for a family member with additional needs, with trustees deciding on extra payments for health or care costs.

Watch-outs and practical workarounds

Charges and admin: Provider and legal costs can add up.
Workaround: Keep the trust’s scope tight, use a short deed, and centralise documents in a shared folder for trustees.

Tax basics: Different trusts are taxed differently. Discretionary trusts, for example, have their own rates and bands.
Workaround: Keep clear records of income and expenses, and use form R185 to show who received what.

Too many trustees: Five trustees can stall decisions and create confusion.
Workaround: Pick two or three trustees and name reserves in case someone steps down.

Vague wishes: “Use it wisely” isn’t enough.
Workaround: Write specific examples—education, deposit, equipment for a trade—and set clear priorities.

Changing circumstances: Life changes, and so might your wishes.
Workaround: Review your trust deed and letter of wishes every few years, especially after major life events.

What to do next

• Write the purpose and beneficiaries in your own words.

• Sound out your preferred trustees—confirm they’re willing and understand the role.

• Get a short trust deed drafted and add a simple letter of wishes.

• Open a trust account and move the first amount in.

• Set a monthly 10-minute slot for notes and receipts so R185 is easy later.
