Should You Write Your Life Insurance in Trust?

Writing your life insurance in trust gets the money to your family faster, can keep it out of inheritance tax, and lets you decide who receives it. Here is how trusts work, in plain English.

Updated June 2026Protection7 min read

You have taken out life insurance to look after the people you love. You have picked the cover, answered the health questions, and set up the direct debit. Job done. Except there is one more step that costs nothing, takes about ten minutes, and that a surprising number of people never do: writing the policy in trust.

Skip it, and the payout your family is counting on can be slower to arrive, smaller after tax, and in some cases end up with the wrong person entirely. Do it, and you fix all three. Here is what a trust actually is, and why a single life policy in particular should almost always be written into one.

Watch: should you write your life insurance in trust?

First, what is a trust?

A trust sounds like something only the wealthy bother with. It is not. At its simplest, a trust is just a legal arrangement where one set of people looks after something on behalf of another. Three roles make it work:

  • The settlor. That is you, the person who sets the trust up and puts something into it. In this case, your life insurance policy.
  • The trustees. The people you choose to look after the policy and, when the time comes, to receive the payout and pass it on. You can be a trustee yourself while you are alive, and you name others to act when you are gone.
  • The beneficiaries. The people you want the money to go to. Your partner, your children, whoever you choose.

Think of it like handing a sealed envelope of instructions to someone you trust, with your family's name on the front. You stay in charge while you are here, and the moment you are not, the people you picked can act straight away, without waiting for anyone's permission.

What writing a policy in trust actually means

When you write your life insurance in trust, you are saying that the policy, and the payout it produces, no longer belongs to you personally. It belongs to the trust, held by your trustees for your beneficiaries. Legally, that one change has three powerful effects.

Why it matters: the three big reasons

1. The money reaches your family faster. When someone dies, their personal assets usually cannot be touched until probate is granted, the legal process of proving a will and settling an estate. Probate routinely takes months, sometimes the better part of a year. A life insurance payout that falls into your estate has to wait in that queue. A policy in trust does not. Because the money belongs to the trust rather than to your estate, your trustees can claim it directly, often within weeks, exactly when your family needs it most to cover the mortgage and the bills.

2. It can keep the payout out of inheritance tax. This is the big one. If your life insurance is not in trust, the payout is added to the value of your estate when you die. If your estate is then worth more than the inheritance tax nil-rate band, currently £325,000 and frozen until 2030, everything above that threshold can be taxed at 40%. A £300,000 life payout landing on top of a house that is already near the threshold can drag a large chunk into a 40% tax charge. Written in trust, the payout sits outside your estate, so it is not counted, and your family keeps the full amount.

3. You decide who gets it, and it cannot be argued over. A policy paid into your estate is distributed according to your will, or if you have no will, according to the rigid rules of intestacy, which may not match your wishes at all. A trust lets you name your beneficiaries directly, so the right people receive the money without it being tied up in, or contested as part of, the rest of your estate.

Why single life policies in particular should be in trust

This is where it really bites. A joint life policy, the kind many couples take out, usually pays on the first death straight to the surviving policyholder, so the money has an obvious home even without a trust, though a trust can still help on the second death.

A single life policy has no such safety net. It is one person's policy, on one person's life. If that person dies and the policy is not in trust, the payout has nowhere to go but into their estate. That means it joins the probate queue, it gets counted for inheritance tax, and it is shared out under their will or the intestacy rules. For an unmarried partner this is especially dangerous: intestacy rules do not recognise an unmarried partner at all, so a single life policy left out of trust could pass to relatives rather than to the partner it was meant to protect.

In short, for a single life policy, a trust is not a nice-to-have. It is usually the difference between the money doing its job and the money getting stuck.

A quick word on naming a beneficiary

People often assume that ticking a beneficiary box on the application does the same job as a trust. In the UK, for most life insurance, it does not. Unlike a pension, a simple beneficiary nomination on a life policy is not legally binding on where the money goes. A trust is the proper mechanism that actually directs the proceeds. If you want certainty, you want a trust.

Bare or discretionary? The two common types

You do not need to be an expert here, but it helps to know there are broadly two flavours:

  • An absolute (or bare) trust fixes your beneficiaries from the start. It is simple, but you cannot change who benefits later, even if your circumstances change.
  • A discretionary trust names a class of potential beneficiaries and lets your trustees decide who gets what, guided by a letter of wishes you leave them. It is more flexible, which is why it is often preferred when family circumstances might change over the years.

Which is right depends on your situation, and it is worth a short conversation rather than guessing.

How to set it up, and yes, it is usually free

The good news is that this rarely costs anything. Most insurers have a standard trust form, and you can complete it when you take the policy out, or add it to an existing policy later. You choose your trustees and beneficiaries, sign, and it is done, often in a few minutes. There is no separate solicitor's bill for a standard provider trust, though for larger or more complicated estates taking proper advice is money well spent.

Already have a policy? You can still put it in trust

Here is the part many people do not realise: you do not have to do this when the policy starts. If you took out life cover years ago and it is not in trust, you can almost always put that right now. Contact your existing life insurance company and ask for their trust form. They will send it over, you complete it with your chosen trustees and beneficiaries, sign it, and return it. There is usually no charge, and your cover carries on exactly as before. The only thing that changes is where the payout will go. If you are not even sure whether your policy is already in trust, your insurer can tell you in a single phone call, and it is well worth making.

The catch: what to weigh first

A trust is powerful precisely because it is firm, and that cuts both ways:

  • It is largely irreversible. Once the policy is in trust, you have given it away. You cannot simply take it back or freely change the terms, so it is worth getting the trust type and beneficiaries right at the outset.
  • Choosing trustees matters. Pick people you trust to act sensibly and who are likely to outlive you. You can act as a trustee yourself, but you should always appoint at least one other.
  • Big or complex estates need advice. Discretionary trusts can have their own tax rules for very large sums, and inheritance tax planning as a whole goes well beyond a single policy. For anything substantial, speak to a solicitor or estate planner.

The common mistakes

  • Never setting a trust up at all, the single most frequent and most expensive oversight.
  • Assuming a beneficiary nomination is the same thing. It is not.
  • Setting one up years ago and never reviewing it after a divorce, a new partner, or new children.
  • Leaving a single life policy, especially for an unmarried couple, out of trust entirely.

The bottom line

Writing your life insurance in trust is one of the highest-value ten minutes in personal finance. It speeds the money to your family, can keep it clear of a 40% tax charge, and makes sure it lands with the people you chose. For a single life policy, it should be close to automatic.

If you already have cover, it is worth a quick check whether it is in trust, and putting it right if it is not. As above, that is usually a free form from your own insurer that you can sort yourself, no adviser needed. If reading this has made you realise you have no life cover at all, or not enough to clear the mortgage and look after your family, that is worth acting on: a whole-of-market protection adviser can arrange new cover and write it in trust from the outset, usually with no charge for the protection advice itself, as the adviser is paid by the insurer. For more on the cover itself, see our guide to life insurance vs critical illness cover and our wider protection guides. Wills and inheritance tax planning sit outside protection advice, so for those it is worth speaking to a solicitor or estate planner.

FAQs

Life insurance in trust FAQs

Should I write my life insurance in trust?
For most people, yes. Writing a policy in trust means the payout reaches your family faster by avoiding probate, sits outside your estate so it is not added to your inheritance tax bill, and goes to the people you choose. It is usually free to set up. For a single life policy in particular it should be close to automatic.
Can I put an existing life insurance policy in trust?
Yes. You do not have to do it when the policy starts. Contact your existing life insurance company and ask for their trust form, complete it with your chosen trustees and beneficiaries, and return it. There is usually no charge and your cover continues unchanged.
Does putting life insurance in trust avoid inheritance tax?
It can. A policy not in trust is added to your estate, and anything above the nil-rate band, currently 325,000 pounds, can be taxed at 40%. Written in trust, the payout sits outside your estate, so it is not counted for inheritance tax. Larger or complex estates should take advice, as trusts have their own rules.
How do I put my policy in trust, and is it free?
Most insurers have a standard trust form you can complete when you take the policy out or add later. You name your trustees and beneficiaries, sign, and return it, often in minutes. There is normally no charge for a standard provider trust.
Do single life policies need to be in trust?
Almost always. A single life policy has no surviving policyholder to pay, so without a trust the payout falls into your estate, faces probate delays and possible inheritance tax, and is shared out under your will or intestacy. For unmarried couples this is especially risky, as intestacy does not recognise an unmarried partner.
What is the difference between a bare and a discretionary trust?
A bare or absolute trust fixes your beneficiaries from the start and cannot be changed. A discretionary trust names a class of potential beneficiaries and lets your trustees decide, guided by your letter of wishes, which is more flexible if your family circumstances might change.
