Protecting Your Children's Inheritance with Trusts

The short answer

If you want to make sure the money or property you leave your children actually stays with them and their bloodline, a trust is usually the most reliable tool. Leaving an inheritance outright gives your child full ownership the moment you die, which means it is exposed to their divorce, their creditors, their own care fees in old age, and even to a new spouse who could inherit it after your child dies. Putting the inheritance into a trust changes the legal ownership: the assets are held by trustees for your children's benefit rather than being your children's personal property. That single change is what lets a trust ring-fence an inheritance against events you cannot foresee.

This is a planning decision with real tax and legal consequences, so treat what follows as a guide to your options in England and Wales rather than a substitute for advice from a qualified estate planner.

What a straight gift can't protect against

Most parents assume a simple will leaving everything to the children is enough. It often is. But an outright gift has no defences once it lands in your child's hands. Consider the common risks:

• Divorce. Money your child inherits can be drawn into the matrimonial pot, particularly if it has been mixed with joint finances or used for the family home. A divorce settlement could see half of what you left walk out of the door with an ex-partner.
• Creditors and bankruptcy. If your child runs a business that fails or faces a personal claim, an outright inheritance is an asset their creditors can reach.
• A new relationship after you die. If you leave everything to your spouse outright and they later remarry, your children can be unintentionally disinherited — a particular worry in blended families.
• Their own care fees. An inheritance your child still owns decades later can be assessed when they need residential care.
• Youth or vulnerability. A young adult inheriting a large sum outright at 18 may not be ready to manage it, and a vulnerable beneficiary may lose means-tested benefits.

A trust addresses every one of these because the inheritance never becomes an asset your child personally owns and controls.

How a trust ring-fences inheritance

A trust separates legal ownership from benefit. The trustees hold the assets and make decisions; the beneficiaries (your children, and often grandchildren) are the people who can benefit. Because no individual beneficiary has an automatic right to a fixed share, there is often nothing concrete for a divorce court, a creditor or a care assessor to attach to. If you are new to the structure, our overview of what a trust is explains the moving parts in plain English.

Crucially, protection does not mean your children miss out. Trustees can distribute income and capital, lend money, or let a beneficiary live in a trust-owned home. The inheritance is still working for your family — it is simply held in a way that strangers to the family cannot easily reach.

Which type of trust?

The most flexible and protective option is usually a discretionary trust. Here you name a class of potential beneficiaries (for example "my children and grandchildren") and give the trustees complete discretion over who receives what and when. Because no beneficiary is entitled to a specific share, a discretionary trust is the hardest for a divorce court or creditor to treat as the beneficiary's own asset. It is the workhorse of inheritance protection and sits at the heart of most family trust arrangements.

Where you want a surviving spouse to be looked after for life but the capital ultimately preserved for your children, a life interest trust is often the answer (see below). For a straightforward gift to a child who will simply receive it at 18, a bare trust exists, but it offers little protection because the child is absolutely entitled — so it is rarely the right choice when shielding inheritance is the goal.

Protecting against a surviving spouse's new partner

This is the classic blended-family problem. If you leave everything to your husband or wife outright and they remarry, your estate could ultimately pass to the new spouse and their family, cutting out your own children. A life interest trust (also called an interest in possession or "right to occupy" trust) solves this elegantly: your surviving spouse gets the right to live in the family home and to receive any income for the rest of their life, but when they die the underlying capital passes to your children under the terms you set — not to whomever your spouse later chooses. Your spouse is secure; your children's inheritance is locked in.

Controlling money for young or vulnerable children

Trusts also let you control when and how children benefit. You can direct that capital is held until a child reaches an age you consider sensible — 21, 25 or beyond — with trustees meeting education, housing and other needs in the meantime. For a disabled or vulnerable child, a discretionary or disabled person's trust can preserve means-tested benefits and protect them from financial abuse, because the money is never theirs to be claimed against or mismanaged. If you also want to benefit the next generation, our guide on leaving money to grandchildren covers how trusts skip a generation safely.

The tax trade-offs

Protection comes with a tax dimension you must weigh up. Most protective trusts are relevant property trusts, which means:

• A potential 20% entry charge on amounts above your available nil-rate band if the trust is created in your lifetime (will trusts created on death are treated differently).
• A periodic charge of up to 6% on the value above the nil-rate band every ten years.
• Exit charges when capital leaves the trust.
• Income taxed at trust rates, and capital gains tax on disposals.

For many families this is modest or nil, because amounts within the £325,000 nil-rate band attract no entry or periodic charge. A life interest trust for a surviving spouse also benefits from the spouse exemption on the first death. The detail matters, so read our explainer on how trusts are taxed and model the figures before committing. The protection is often well worth the cost — but it should be a deliberate, informed choice.

Choosing trustees and getting it right

A protective trust is only as good as the people running it. Trustees control the assets and exercise the discretion that gives the trust its strength, so choose people who are trustworthy, financially capable and likely to outlive you — and appoint at least two. You should also leave a clear, non-binding letter of wishes explaining how you would like them to use their discretion, which guides them without creating the kind of fixed entitlement that would undermine the protection. Trustees take on real legal obligations, set out in our guide to trustee duties and responsibilities.

Two final points of realism. First, no trust is bulletproof: the divorce courts can in some circumstances treat a trust as a financial resource or vary a nuptial settlement, so timing and genuine discretion matter, and last-minute trusts created to defeat a known claim are vulnerable to challenge. Second, this is technical, high-stakes planning where the wrong structure can cost far more in tax than it saves in protection. Because the law and the tax interact in complex ways, professional advice from a qualified estate planner is strongly recommended before you put any inheritance into trust.
