Should life insurance be written in trust?

7 September 2026

A trust normally costs nothing, takes one form, and decides whether your family waits months or weeks for the money.

The short answer

Usually yes, and it normally costs nothing. A trust keeps the payout outside your estate, so it is not counted against the £325,000 Inheritance Tax threshold and does not wait for probate. It also directs the money to the people you named, which matters most for unmarried couples.

What does putting life insurance in trust do?

A trust is a legal arrangement that separates who owns the policy from who benefits from it.

You name trustees to hold the policy and beneficiaries to receive the money.

The practical effect is that the payout does not belong to your estate when you die.

It goes to your trustees, who pass it to the people you named, without waiting for the estate to be settled.

Three things a trust changes.

The money usually falls outside your estate for Inheritance Tax. It does not wait for probate. And it goes to the people you chose rather than the people the law chooses.

Life insurance in trust and Inheritance Tax

Inheritance Tax is charged at 40 per cent on the part of an estate above the threshold.

The standard threshold is £325,000. It can rise to £500,000 where a home is passed to children or grandchildren.

Anything left to a spouse or civil partner is exempt, and an unused threshold can transfer to them.

A life insurance payout that is not in trust normally forms part of your estate.

So a £300,000 policy can push an estate over the threshold and generate a tax charge that the policy itself then has to pay.

In trust, the same payout usually sits outside the estate entirely.

Worth being precise here.

If everything passes to a spouse or civil partner, Inheritance Tax is not the reason to use a trust. Speed and control are. For unmarried couples and for larger estates, the tax point is real.

How a trust avoids waiting for probate

Probate is the legal right to deal with someone's property, money and possessions after they die.

GOV.UK is blunt about the timing consequence. You should not make financial plans or put a property on the market until probate is granted.

That is the part people miss. Without a trust, the insurer usually cannot pay until the estate has authority to receive the money.

Meanwhile the mortgage is still due, the funeral has to be paid for, and the household has lost an income.

With a trust, the trustees claim directly. The money can reach the family in weeks rather than waiting on the estate.

This applies whether or not you would ever pay Inheritance Tax, which is why it matters to almost every household.

Who should put life insurance in trust

Situation	Is a trust usually worth it
Unmarried couple, mortgage in joint names	Yes. Without one, an unmarried partner may inherit nothing.
Married, estate comfortably under the threshold	Often yes, for speed rather than tax.
Married, estate over the threshold with the policy included	Yes. This is where the 40 per cent charge bites.
Children from a previous relationship	Yes. A trust lets you direct the money precisely.
Business partners with cover on each other	Yes, and it usually needs a specific business trust.
Mortgage protection where the lender is repaid	Still usually yes, because the money reaches the survivor faster.
Cover written to pay an unrelated third party already	Take advice. The arrangement may already achieve it.

The unmarried couple case is the most urgent and the least understood.

Under the intestacy rules in England and Wales, an unmarried partner has no automatic right to inherit, however long you lived together.

So a policy meant for a partner can end up with a parent or a sibling instead.

How to put life insurance in trust

Most insurers provide their own trust forms free of charge, and there is normally no fee to use them.

Decide who your trustees will be. Choose at least two, and make sure they are people who would act.
Decide who the beneficiaries are, and whether you want fixed shares or flexibility to change them later.
Complete the insurer's own trust form rather than a generic one, because it is drafted for that policy.
Have it witnessed correctly. A form that is not witnessed properly may not be valid.
Tell your trustees it exists and where the paperwork is. A trust nobody knows about does not help anyone.
Review it after a marriage, a divorce, a birth or a death.

It can be done on a policy you already hold, not only on a new one.

If you have had cover for ten years with no trust, that is fixable this week.

Trusts have legal and tax consequences. Writing a protection policy in trust is normal adviser work. A complex estate needs a solicitor as well. Complex means a business, a second family or an asset held overseas.

Frequently asked questions

Does putting life insurance in trust cost anything?

Usually nothing. Most insurers provide their own trust forms free, and an adviser normally completes them as part of arranging or reviewing the policy.

Does a trust avoid Inheritance Tax on life insurance?

It normally keeps the payout outside your estate, so it is not counted against the £325,000 threshold or taxed at 40 per cent. If everything passes to a spouse or civil partner it would be exempt anyway, so the benefit there is speed rather than tax.

Can I put an existing policy in trust?

Yes. A trust can be added to a policy you already hold. Ask your insurer for their trust form, or ask an adviser to review the policies you already own.

Who should I choose as trustees?

People who would actually act, and at least two of them. Many people name a partner plus one other adult they trust. You can usually be a trustee yourself alongside them.

Do I still need a will if my policies are in trust?

Yes. A trust deals with the policy, not with the rest of your estate. Without a will, the intestacy rules decide everything else, and they do not recognise unmarried partners.

Can I change the beneficiaries later?

It depends on the type of trust. A flexible or discretionary trust allows change, while an absolute trust generally fixes the beneficiaries from the start. Ask which one the form creates before you sign it.
