Picture this. A mother in Leicestershire has a son with a learning disability. He’ll never be able to manage a large sum of money on his own, and if she leaves him an inheritance outright, it could be swallowed up by care costs or put his means-tested benefits at risk. She’s not alone. We speak to families like this every week, and it’s exactly the kind of worry that a vulnerable person trust is designed to solve.

At Paradigm Wills, we help families across the UK plan for a disabled child, sibling, or parent in a way that protects their money, benefits, and dignity. In this guide, we’ll explain what a vulnerable person trust actually is, who qualifies, and why it might be one of the most valuable things you put in your will.

What Is a Vulnerable Person Trust?

A vulnerable person trust is a type of trust created specifically to hold and manage money or property on behalf of someone who is unable to manage their own affairs, whether that’s because of a physical disability, a learning disability, or a mental health condition recognised under the Mental Health Act 1983. Rather than leaving assets directly to the individual, which could unintentionally put them at financial risk, the assets sit within the trust and are managed by trustees you choose, usually family members or a professional adviser.

We often describe it to clients as building a protective shell around the money. The vulnerable individual still benefits from it, but they’re not exposed to the pressures of managing a large sum alone.

Who Actually Counts as a Vulnerable Person?

This is one of the most common questions we get asked, and the answer is more specific than most people expect. Under HMRC’s rules, someone generally qualifies as a disabled person for these purposes if they receive or are eligible for certain disability-related benefits, such as Personal Independence Payment or the older Disability Living Allowance, or if they have a condition that means they’re unable to manage their own affairs.

This matters because according to the House of Commons Library, an estimated 16.8 million people in the UK had a disability in 2023/24, which is around a quarter of the population. That’s a huge number of families who could, in most cases, benefit from thinking about this kind of planning, whether that’s for a child, a spouse, or a parent.

The Tax Benefits That Make These Trusts So Valuable

This is where a disabled person trust really earns its keep, because it’s treated very differently for tax purposes than a standard discretionary trust.

• Income Tax. Ordinarily, trustees of a discretionary trust pay a much higher rate of tax on trust income than an individual would. With a qualifying vulnerable persons trust, trustees can make what’s called a vulnerable person election, which allows the trust’s tax on income to be calculated broadly as if the money had gone directly to the disabled beneficiary rather than being taxed at the higher discretionary trust rate. This alone can make a substantial difference over the years.

• Capital Gains Tax. Trusts for vulnerable beneficiaries also get a more generous capital gains tax allowance. According to the UK Government, for the 2025 to 2026 tax year, ordinary trusts have a much smaller tax-free allowance than trusts qualifying for vulnerable beneficiary treatment, which benefit from the full personal tax exemption rather than the reduced trust rate.

• Inheritance Tax. This is often the part families find most reassuring. Trusts set up for a disabled person are usually exempt from the ten-yearly periodic charges and exit charges that apply to most discretionary trusts. In most cases, as long as the person setting up the trust survives seven years from creating it, there’s no inheritance tax charge on the transfer into the trust either.

Put simply, a trust for tax purposes that qualifies as a vulnerable persons trust is treated far more favourably than a standard family trust, which is exactly why we recommend families look into this properly rather than defaulting to a basic discretionary arrangement.

Protecting Against the Risk of Financial Abuse

Beyond the tax position, there’s a quieter but equally important reason families choose these trusts. Individuals who are unable to manage their own affairs are, sadly, more vulnerable to financial abuse, whether from a well-meaning but careless family member, a scammer, or someone taking advantage of a vulnerable individual’s trust.

Because the assets are held and controlled by appointed trustees rather than by the vulnerable beneficiary directly, there’s a built-in layer of protection. Trustees have a legal duty to act in the beneficiary’s best interests, and decisions about spending are made with proper oversight rather than left to chance.

How We Help Families Set One Up

We know none of this feels simple when you’re reading it for the first time, and that’s the whole point of what we do. When we sit down with a family, we walk through:

• Whether the person you’re planning for meets the definition of a vulnerable person for tax purposes
• Who should act as trustees, and how many
• How the trust should be worded in your will so it qualifies for the tax treatment described above
• How the trust will interact with any means-tested benefits the person currently receives or may receive in future

It’s worth speaking to an adviser about your specific circumstances before finalising anything, because the qualifying conditions and paperwork, including the election forms HMRC requires, need to be handled correctly for the special treatment to apply.

What Happens If You Don’t Plan Ahead

We’re not here to alarm anyone, but it’s worth being honest. Without a vulnerable person trust in place, an inheritance left directly to a disabled loved one could reduce or stop their entitlement to means-tested benefits overnight, and the money itself could be far less protected than most families assume.

According to research, disabled households already face around £1,095 in extra costs every month compared to non-disabled households, so getting this planning right isn’t a luxury. It’s about making sure the support you leave behind actually reaches, and helps, the person it’s meant for.
