Life insurance written in trust: how the structure works

Why writing it in trust matters

A life insurance policy that is not written in trust adds its full payout to your estate. That single fact drives everything else in this guide. The payout stacks onto the house and savings when the estate is measured against the £325,000 nil-rate band, so anything above the allowances can suffer 40% inheritance tax, and the money then sits frozen with the insurer until the executors obtain the grant of probate. Writing the same policy in trust removes it from that picture entirely: the policy belongs to the trustees from the day the trust deed is signed, the payout never enters the estate, and the trustees can normally claim it with little more than a death certificate. Same policy, same premiums, very different result.

This guide looks at the structure from the estate administration side: what it does to the inheritance tax bill, to the probate timeline, and to the job the executors have to do. The law described covers England and Wales, and everything here is general information rather than legal or financial advice for your own situation.

Why a policy not in trust lands in the estate

GOV.UK's guidance on estimating an estate's value is explicit that the assets to include cover payments made because the person died, giving life insurance as its example alongside pension death benefits. HMRC's Inheritance Tax Manual confirms the mechanics at IHTM20211: where the deceased owned a policy on their own life and it was not connected with a trust, the value transferred on death is the full claim value, with no discount for the fact that the insurer will insist on paperwork before paying.

Two practical consequences follow.

• The tax effect. The payout stacks on top of the house, savings and everything else when the estate is measured against the £325,000 nil-rate band (and the residence nil-rate band where it applies). A policy bought precisely to look after the family can push the estate into tax, or deepen an existing bill, at 40% on the excess. Our guide to the inheritance tax threshold sets out how the bands work.
• The timing effect. Because the money is owed to the estate, the insurer generally pays the executors, and the executors generally cannot collect estate assets of any size until probate is granted. That is routinely a wait of several months. A surviving partner facing a mortgage payment next week gets no comfort from a six-figure sum that is legally theirs but administratively out of reach. Our probate timeline estimator gives a realistic sense of that wait, and our probate pillar guide explains the process end to end.

What writing the policy in trust changes

Writing a policy in trust means executing a trust deed, almost always on the insurer's own template, that transfers ownership of the policy to trustees. You typically appoint yourself as a trustee alongside one or two others, you carry on paying the premiums, and your life remains the one insured. But the rights under the policy now belong to the trustees, held for the beneficiaries named in the deed.

On death, the insurer pays the trustees, not the estate. The payout is not an estate asset, so it is not counted in the inheritance tax valuation and it does not wait for probate. Trustees can usually complete a claim with the trust deed and the death certificate, which is why trust-held payouts often arrive within weeks while the estate itself is still months from a grant. For a family that has just lost an income, that speed is frequently worth more than the tax saving.

A worked example: the policy that creates the whole tax bill

Take a widowed teacher in Nottingham with a £350,000 home left to her two adult children, £150,000 of savings and investments, and a £200,000 level term life insurance policy in her own name.

Policy not in trust. Her estate is £350,000 + £150,000 + £200,000 = £700,000. Her allowances are the £325,000 nil-rate band plus the £175,000 residence nil-rate band (the home passes to direct descendants), £500,000 in total. Tax: 40% of £200,000 = £80,000. Every pound of that bill exists because of the insurance payout; without it the estate would have been exactly covered by her allowances. The children also wait for probate before the insurer releases the money.

Policy written in trust. Her estate is £500,000, fully covered by her allowances. Tax: nil. The trustees claim the £200,000 directly and can pass it to the children within weeks. The paperwork that produced this difference was a trust form the insurer supplied without charge. You can test your own position with our IHT threshold calculator, once including a policy payout in the estate and once leaving it out; the gap between the two results is what the trust structure is protecting.

Bare or discretionary: the two usual trust types

Insurers' trust forms generally come in two flavours, and the choice matters more than most people realise when they tick the box.

A bare trust (often labelled an absolute trust) names fixed beneficiaries with fixed shares. As GOV.UK's guide to trust types explains, a bare trust's assets are held in the trustees' name but the beneficiary has the right to all of the capital and income once they are 18. That certainty cuts both ways: the structure is simple and stays outside the heavier trust tax rules, but the beneficiaries can never be changed. Name a partner today and the gift is theirs even if you separate tomorrow.

A discretionary trust instead names a class of potential beneficiaries, perhaps "my children and grandchildren", and gives the trustees power to decide who receives what and when. GOV.UK describes these as trusts where the trustees can decide how the income, and sometimes the capital, is used. Policyholders usually leave a letter of wishes to guide the trustees. The flexibility is valuable in blended families or where beneficiaries are young, but it comes with a tax caveat of its own.

The discretionary caveat: periodic charges

Assets in a discretionary trust are "relevant property", and GOV.UK's guidance on trusts and inheritance tax confirms that relevant-property trusts face inheritance tax charges at each 10-year anniversary, plus exit charges when assets leave the trust. The rate is up to 6% of the value above the trust's available nil-rate band.

For most life policy trusts this bites rarely in practice, because a term policy that has not paid out is usually worth little or nothing at a 10-year anniversary, so the charge computes to nil or close to it. The exposure appears when the trust is actually holding money: if the person dies and the trustees retain the payout rather than distributing it promptly, a six-figure sum can be sitting in a relevant-property trust when an anniversary falls or when funds exit. Our sibling guide to inheritance tax on trusts and the 10-year charge works through the calculation. Bare trusts sit outside this regime entirely, which is part of their appeal despite the inflexibility.

Premiums are still gifts

One distinction is worth stating carefully: the trust keeps the payout outside your estate, but the premiums you keep paying are gifts, because you are funding a policy you no longer own. Each premium is a transfer of value with its own inheritance tax analysis.

In practice this is rarely a problem, but it should be a deliberate rather than accidental outcome. GOV.UK's guidance on gifts confirms the two exemptions that usually do the work: the £3,000 annual exemption (with one year's carry-forward), and the normal expenditure out of income exemption for regular payments made from surplus income that do not dent your standard of living. Monthly premiums paid comfortably out of salary or pension income are a textbook fit for the second of these; our sibling post on the normal expenditure out of income exemption explains how to document it so executors can claim it later. Premiums not covered by an exemption are potentially exempt transfers that drop out of account only if you survive seven years.

What executors should check, early

Whether a policy was written in trust changes three things for whoever administers the estate: who the insurer will pay, how fast, and whether the sum belongs on the estate's inheritance tax valuation. So it is a day-one question, not a detail to tidy up later.

1. Find every policy, then find the deed. Look for policy schedules, direct debits to insurers, and any document titled "trust deed" or "deed of appointment". Ask the insurer directly whether the policy is recorded as trust-held.
2. If a trust exists, hand the claim to the trustees. The money is theirs to collect and it stays off the estate valuation. Note that GOV.UK's rules on checking the type of estate mean trust interests can still affect whether a full IHT400 account is needed, for example where the deceased held assets worth over £250,000 in trust.
3. If there is no trust, the payout is an estate asset. Include it at full claim value in the valuation, expect the insurer to require the grant before paying, and plan estate cash flow accordingly.

Our executors hub covers the wider administration job, and our guide for surviving spouses deals with the situation where the payout is the money the household actually needs to live on while probate grinds through.

Setting one up, and where advice comes in

Mechanically, writing a policy in trust is straightforward: insurers supply their own trust forms, usually at no extra cost, and both new and existing policies can normally be placed in trust. There is typically no need for a solicitor to draft anything from scratch.

But easy paperwork is not the same as an easy decision. A trust is effectively irrevocable, a bare trust locks in beneficiaries permanently, a discretionary trust brings the relevant-property rules into play, and the right structure depends on your family, your estate's size against the inheritance tax thresholds, and how the policy fits with pensions and other death benefits.

The practical route, then, has two steps. First, ask your insurer for its trust form; nearly every provider has one ready, usually free, and it works for existing policies as well as new ones. Second, before you sign it, put the trust-type question to a financial adviser authorised by the FCA, because choosing whether and how to place a specific policy in trust is advice that only an authorised adviser can give. If the wider estate planning around the policy needs attention too, we can put you in touch with an estate-planning specialist. Set against the £80,000 bill in the worked example above, a free form and one properly advised decision is about the best value planning an estate ever gets.
