If you want to leave money to your children from your first marriage and be certain they actually receive it the day you die, the surest way is not a line in your will. It is a life policy written in trust for them by name. That single arrangement pays the children directly, ahead of probate, and it cannot be redirected afterwards by anyone who outlives you — including a new spouse.
The reason to reach past the will is that a will is a weaker instrument than most people assume in a second-family situation. Anything you leave to your new husband or wife becomes theirs to keep, to spend, and to leave to whomever they choose. Good intentions expressed at the graveside do not bind them. So if your plan is "everything goes to my spouse, and they will look after my children," you are relying on a promise the law will not enforce.
A policy in trust breaks that dependency. It carves out a defined sum, ring-fences it for the children you name, and hands it to trustees you have chosen, entirely separately from the estate your spouse inherits. Below is exactly how it works, how to set it up so nobody can unpick it, and how it lets you still leave the house and the rest to your spouse without pitting the two families against each other.
At a glance
- A life policy written in trust for named children pays the trustees directly, without waiting for a grant of probate.
- The proceeds sit outside your estate, so they are not governed by your will and cannot be redirected by a later will or a surviving spouse.
- They are normally outside your estate for inheritance tax as well, which the estate route often is not.
- Your will can still leave the house and everything else to your new spouse, because the trust handles the children separately.
- Set the trust up at the outset, appoint at least two trustees, and tell them it exists — a trust nobody knows about goes unclaimed.
The short answer: use a trust, not just the will
A will decides who gets your estate. A trust holds a specific asset for specific people, on terms you set, outside that estate. For provision you want to be certain of, the trust is the stronger tool, because it removes the money from every process and every person that could otherwise divert it.
When you write a life policy in trust, you are saying that the payout does not belong to you when you die — it belongs to the trust, for the benefit of your named children. That has three consequences that all point the same way. The insurer pays the trustees on production of the death certificate, not after a grant of probate. The money never forms part of the estate your spouse inherits, so it cannot be swallowed by other claims on it. And because it is not in your will, a later will cannot touch it.
This is the mechanism the rest of this article unpacks. It is not exotic, it is not expensive to arrange, and most insurers provide the trust forms without charge. It is simply the difference between hoping the right people end up with the money and making sure of it.
Why the will alone cannot guarantee it
Leaving everything to a new spouse and trusting them to pass some on to your first family fails in more ways than people realise, and none of the failures require any bad faith.
The most common is remarriage. In England and Wales, and in Northern Ireland, marriage automatically revokes an existing will unless it was made specifically in contemplation of that marriage. So a surviving spouse who remarries can find their old will torn up by operation of law, and the intestacy rules then favour their new husband or wife — your children from the first marriage can drop out of the picture entirely, without a single deliberate decision being made against them.
Even without remarriage, a surviving spouse is free to make a new will at any time and leave everything elsewhere. Mutual wills, where two people promise not to change their arrangements, are notoriously fragile and litigated. And an outright gift to a spouse is theirs to spend: it can be eroded by care costs, by a business, by a second family, by ordinary life, long before it ever reaches your children. You can see how the raw intestacy figures play out for a surviving spouse in the statutory legacy in a second marriage, and how the family home specifically gets caught in a second marriage with one house and children from the first.
A policy in trust is immune to all of this. It is not in the will that remarriage revokes. It is not part of the estate a new will can redirect. It does not depend on a spouse keeping a promise. It is settled the day you sign the trust, and nothing anyone does after your death can move it.
What writing a policy in trust actually does
Putting a policy in trust means you no longer own the policy outright. You transfer it to trustees, to hold for the beneficiaries you name — here, your children from your first marriage. You are the person whose life is insured, but the benefit belongs to the trust.
The practical payoff shows up at the worst time, when speed matters. Because the proceeds are not part of your estate, the trustees do not need a grant of probate to claim them. They contact the insurer, provide the death certificate and proof of their own identity, and the insurer pays the trust. Grants of probate commonly take several months to issue, and the estate is frozen until they do — a policy in trust simply does not join that queue.

The second effect is on inheritance tax. Because the payout is outside your estate, it is normally not counted when the tax on your estate is worked out. Contrast that with a policy left through the will, which falls into the estate and can push its value up. This is general information rather than advice on your own position — how it applies depends on the trust being set up correctly and on your wider estate — but the direction of travel is clear, and it is one of the main reasons protection policies are so often placed in trust.
Choosing the trust and the trustees
There are broadly two shapes of trust for this, and the right one depends on how much certainty against how much flexibility you want.
A bare trust names fixed beneficiaries with fixed shares — for example, your two children from your first marriage, half each. It is simple and certain: those people get those shares, and a bare trust beneficiary is entitled to their share outright at eighteen. Choose it when you know exactly who should get what and you want no ambiguity. A discretionary trust instead gives the trustees a class of beneficiaries and lets them decide who receives what and when. Choose it when circumstances might change, when you want to control the timing, or when one child needs protecting — for instance, someone on means-tested support who should not receive a lump sum in their own name. For most protection policies the choice makes little practical difference to tax while you are alive, because the trust holds only the policy and has no other value.
Whoever the beneficiaries, the trustees are the people who make it work. Appoint at least two, choose people who will act promptly and can be even-handed between the beneficiaries, and consider a mix — an adult child, a trusted sibling, sometimes a professional. You can be a trustee of your own policy alongside them. The single most common failure is not a legal one: it is a trust nobody knew about, so nobody claimed it. Tell your trustees the policy exists and where the paperwork is.
Why level term cover fits a fixed legacy
The amount you want your children to receive is usually a fixed figure — a set legacy that means something, rather than an amount that shrinks over time. That is what level term cover provides: a sum that stays the same throughout the term of the policy, so the payout is the same whether you die in the second year or the last one.
That makes it a better match here than decreasing cover, which is built to fall in step with a mortgage and would leave your children with less the longer you live. With level term written in trust, you are fixing both the amount and its destination: a defined sum, for defined children, delivered through a defined route. If you want that priced against a specific figure and term, you can get life insurance quotes and have an FCA-authorised broker set it out. A payout is never guaranteed in the abstract — it depends on the policy being in force and on the insurer's underwriting — but the structure is designed to do exactly this job.
Cover through an employer's death-in-service scheme can play a part too, though it is a blunter tool for this because you often cannot direct it to specific children with the same certainty. We look at that specific interaction in children from a first marriage and the work payout.
Leaving the rest to your spouse at the same time
None of this asks you to choose between your spouse and your first family, and that is the point of separating the two. The trust deals only with the policy proceeds, which go to the children. Your will is then free to leave the house and the remainder of the estate to your new spouse, without the pressure that usually forces one side to lose.
That pressure is real when everything runs through a single asset. Leave the house to your spouse outright and the children have nothing certain; leave it to the children and your spouse may have to sell the home they live in, or live inside a trust arrangement they did not choose. A separate fund for the children, paid from outside the estate, breaks that deadlock cleanly. The house stays with your spouse; the children's provision arrives on its own terms and its own timetable.
If you and your partner are not married, the same structure carries even more weight, because there is no spouse exemption to fall back on and the intestacy rules would give an unmarried partner nothing. The broader question of whether two parents should insure each other at all is one we take up in should separated parents insure each other?
Scotland and Northern Ireland
The trust mechanism works across the UK, but the surrounding inheritance rules differ, and in one respect the difference makes the trust even more valuable.
In Scotland, children have legal rights — an automatic entitlement to a share of a parent's moveable estate that a will cannot defeat. That protects your children in one way but constrains your planning in another, because it applies to the estate as a whole. A life policy written in trust sits outside the estate, so it is neither reduced by legal rights nor part of the fund they are claimed from: it lets you guarantee a defined sum to your first-marriage children independently of how the legal-rights arithmetic falls. We explain the entitlement itself in Scotland: your children can claim against your estate.
Northern Ireland follows testamentary freedom much as England and Wales do, with no equivalent forced share for children, and marriage there also revokes an earlier will. In every part of the UK the same conclusion holds: a policy written in trust for named children reaches them directly and cannot be redirected, which is precisely why it is the tool people reach for when a first family must be provided for with certainty.
Frequently asked questions
What does writing a policy in trust actually do?
It separates the payout from your estate. The money belongs to the trust, so trustees can claim it without waiting for a grant of probate, it is normally outside your estate for inheritance tax, and it cannot be redirected by a later will or by anyone who outlives you.
Can I still leave everything else to my new spouse?
Yes. The trust deals only with the policy proceeds. Your will can leave the house and the rest of the estate to your spouse, while the children of your first marriage receive the policy. That removes the pressure to sell property or divide it between two families.
Who should the trustees be?
People who will act promptly and can be fair to the beneficiaries, often a sibling, an adult child or a professional. You can be a trustee of your own policy alongside them. Appoint at least two, and tell them the trust exists, because a trust nobody knows about goes unclaimed.
