Life Insurance in Trust UK (2026): How It Works, Types & Why You Need One
Updated 13 May 2026 · 10 min read · England & Wales
Quick answer
A life insurance policy held in your own name falls into your estate on death — subject to 40% inheritance tax and probate delays. Writing it in trust removes the payout from your estate entirely: your family receives the full amount free of IHT, often within weeks rather than months. Most UK insurers provide free trust forms. You still need a will to cover everything else.
What does “writing life insurance in trust” mean?
When you write a life insurance policy in trust, you transfer legal ownership of the policy to a trust rather than holding it in your own name. The trust is a legal arrangement: you (the settlor) set it up, appoint trustees to manage it, and name the people you want to benefit (beneficiaries).
On your death, the insurer pays the policy proceeds to the trustees — not to your estate. The trustees then distribute the money to the beneficiaries according to the trust deed. Because the policy belongs to the trust, not to you, it:
- Is not part of your estate for inheritance tax purposes
- Does not need to wait for a Grant of Probate before it can be paid out
- Cannot be used to pay your personal debts
Why it matters — the cost of not using a trust
Consider a concrete example:
- Estate (excluding life insurance): £400,000
- Life insurance policy (not in trust): £300,000
- Total estate value: £700,000
- Nil-rate band: £325,000
- Taxable amount: £375,000
- IHT at 40%: £150,000
If the same policy had been written in trust, the taxable estate would be £400,000 — NRB of £325,000 = £75,000 taxable. IHT would be £30,000 instead of £150,000. Writing the policy in trust saves £120,000 in this example. And the trust payout is available to the family weeks after death, not months.
The parties to a life insurance trust
| Party | Role | Who this typically is |
|---|---|---|
| Settlor | Sets up the trust, owns the policy before placing it in trust | You (the policyholder) |
| Trustee(s) | Manage the trust and distribute proceeds on death | Spouse/partner + one other trusted adult. Minimum two recommended. |
| Beneficiaries | Receive the payout | Named individuals or a class (e.g. "my children") |
Types of life insurance trust
Discretionary trust
The most commonly used type. Trustees have discretion over who among the class of beneficiaries receives the payout and when. You can guide their decision with a Letter of Wishes (not legally binding but usually followed). A discretionary trust is flexible — beneficiaries can be added or the proportions changed by updating the Letter of Wishes, even if the trust deed itself cannot be changed.
Best for: Most families. Allows trustees to respond to changing circumstances (e.g. a beneficiary going through a divorce or bankruptcy when the payout occurs).
Bare (absolute) trust
Each beneficiary has an immediate, irrevocable right to a fixed share of the proceeds. Once set up, the beneficiaries cannot be changed (without their consent, which they can give if they are adults). Simpler and cheaper to administer.
Best for: Simple situations where you are certain who should benefit and in what proportions — for example, two adult children inheriting 50% each.
Split trust
Used for policies that combine life insurance with critical illness cover. The critical illness element stays in your own name (because you need to claim it yourself if you become ill), while the life insurance element is written in trust. Without a split trust, placing a combined policy in trust means the critical illness payout also goes to the trustees — not to you.
How to write life insurance in trust — step by step
- Contact your insurer. Most UK insurers (Aviva, Legal & General, Royal London, Scottish Widows etc.) offer free trust forms for their policies. Ask at the point of taking out the policy or at any time afterwards.
- Choose the trust type. Discretionary for most families; bare if your situation is simple and fixed.
- Appoint trustees. Name at least two — ideally your partner and one other trusted adult who is not a beneficiary. Trustees must act in the best interests of beneficiaries.
- Name the beneficiaries. For a discretionary trust, name a class ("my spouse and my children"). For a bare trust, name specific people and their shares.
- Complete and sign the trust deed. Both you and the trustees must sign. Keep the original safely (with your will).
- Write a Letter of Wishes. Guide your trustees on how you would like the payout distributed. Update it when your circumstances change.
Can you write an existing policy in trust?
Yes — you can write an existing policy in trust at any time before death, not just when you take it out. For most policies, writing in trust is a straightforward form-signing exercise. However, placing a policy in trust where the surrender value exceeds the nil-rate band may create an immediately chargeable transfer for IHT purposes. Take advice if your policy has significant surrender value.
What writing in trust does NOT do
- It does not replace your will — the trust only covers the policy proceeds. All other assets are governed by your will (or intestacy rules if you have no will).
- It does not protect the payout from a beneficiary's creditors indefinitely (though a discretionary trust offers some protection).
- It does not affect critical illness cover unless you use a split trust.
- It is not easily undone once in place — particularly for bare trusts.

Frequently asked questions
Does life insurance count as part of my estate in the UK?+
Yes — if the policy is held in your own name (not in trust), the payout forms part of your estate on death. This means it is subject to inheritance tax at 40% on the amount above your available nil-rate band, and must wait for probate before it can be paid to beneficiaries. Writing the policy in trust removes it from your estate entirely, so neither charge applies.
How do I write life insurance in trust in the UK?+
Most UK insurers offer free trust forms that you complete at the time of taking out the policy or at any point afterwards. You name yourself as the settlor, appoint trustees (typically your partner and another trusted adult), and specify the class of beneficiaries. The insurer registers the trust. Some insurers require a solicitor for more complex arrangements, but straightforward bare or discretionary trusts are usually DIY.
What type of trust should I use for life insurance in the UK?+
For most people, a discretionary trust is the right choice — it lets trustees decide who among the named class of beneficiaries receives the payout and when, giving flexibility if your circumstances change (divorce, death of a beneficiary). A bare (absolute) trust is simpler and gives named beneficiaries an immediate, irrevocable right to the proceeds — useful if you are certain who should benefit. A split trust is used for policies that combine life cover and critical illness so the critical illness portion stays in your own name.
Can I change the beneficiaries on a life insurance trust in the UK?+
It depends on the trust type. A discretionary trust gives trustees ongoing flexibility to decide which beneficiaries within the named class receive the funds — you cannot change trustees' decisions but you can update a Letter of Wishes to guide them. With a bare (absolute) trust, the beneficiaries' entitlement is fixed at the outset and cannot be changed without their consent. Always review your trust arrangements after major life events.
Does life insurance in trust avoid probate in the UK?+
Yes. Because the policy is owned by the trust — not by you personally — the trustees can access the funds immediately after death without waiting for a Grant of Probate. In practice, payouts from a trust-held policy typically take weeks rather than months. This is especially valuable when your family needs funds quickly to cover funeral costs, mortgage payments, or living expenses while the estate is being administered.
What happens if I die without writing my life insurance in trust in the UK?+
The payout forms part of your estate. Your executor cannot release the funds until probate is granted (currently 4–6 months on average, sometimes longer). The full payout is then added to your estate value and taxed at 40% on the amount above your nil-rate band. For a £500,000 policy in a £600,000 estate with a £325,000 NRB, HMRC would take 40% of £275,000 — a £110,000 tax bill on the insurance payout alone.
Do I still need a will if my life insurance is in trust in the UK?+
Yes — absolutely. Writing life insurance in trust only deals with the policy proceeds. Everything else you own — property, savings, personal possessions, investments — passes through your estate and is governed by your will (or, if you have no will, the intestacy rules). A trust and a will serve complementary functions: the trust keeps insurance money outside probate and IHT; the will controls everything else. You need both.
Your trust covers the policy. Your will covers everything else.
Writing life insurance in trust is free to do through your insurer. The remaining gap — your property, savings, and everything else — is covered by a correctly drafted will. WillSafe UK provides plain-English will kits for England and Wales from £39.99.
