A simple inheritance isn’t always the safest option—here’s how to provide lasting security instead.

If someone you love has a disability, making provision for them in your will requires careful thought. A standard gift of money or property may seem straightforward, but for many disabled people it can cause serious problems rather than provide the security you intended. This guide explains the key issues to consider and the legal tools available to help you plan wisely.

Understanding Disability in the Context of Will Planning

Disability covers an enormous range of circumstances, and the challenges involved in will planning depend very much on the individual and the nature of their condition.

Mental Disability and the Capacity to Manage Affairs

Some people have a mental disability or cognitive impairment that means they are unable to manage their own financial affairs. This might include someone with a learning disability, a form of dementia, or a brain injury. Where a person lacks the mental capacity to deal with money and property, the Court of Protection may already be involved in their affairs, or may become involved following an inheritance. The Court has the power to appoint a deputy to manage funds on the person’s behalf.

While this provides a degree of protection, it also means that an outright gift in your will could effectively pass out of your family’s control and into the hands of a court-appointed deputy, which may not be what you intended at all.

Beyond the formal legal process, there is also a broader concern. People with certain mental impairments can be vulnerable to poor financial decisions or, in more troubling cases, to exploitation by others. A large inheritance paid directly to a vulnerable adult can attract exactly the wrong kind of attention.

Physical Disability and Means-Tested Benefits

The picture is quite different for many people with physical disabilities, or those with certain long-term health conditions. Many are entirely capable of managing their own financial affairs. The challenge here is not one of capacity, but of financial planning.

A significant number of disabled people rely partly or wholly on means-tested benefits such as Universal Credit, Personal Independence Payment (PIP), or Housing Benefit. These benefits are calculated based on the recipient’s financial resources. If a disabled person inherits a sum of money outright, the funds may be treated as capital and counted against them when their benefit entitlement is assessed. In some cases, even a modest inheritance can lead to the loss of benefits entirely, leaving the person financially worse off overall and frustrating your good intentions towards them.

The same concern applies to local authority funding for care. Many disabled people receive support funded by the local authority, but that funding is means-tested. An inheritance could trigger a reassessment and result in the withdrawal of funded care, leaving the person to pay for their own support until the inherited funds are exhausted.

How a Trust Can Protect a Disabled Beneficiary

The solution in both scenarios described above, whether the concern is vulnerability and capacity or the risk of losing means-tested benefits, often lies in the use of a trust.

Rather than leaving money or property directly to a disabled person, a trust allows you to set aside assets for their benefit whilst keeping those assets outside their direct ownership. The trust is managed by trustees, who hold the assets and apply them for the benefit of the disabled person in accordance with the terms you set out in your will.

There are two main types of trust commonly used in this context: discretionary trusts and disabled trusts. They serve similar purposes but operate differently and carry different tax implications.

Discretionary Trusts vs Disabled Trusts: What Is the Difference?

What Is a Discretionary Trust?

A discretionary trust is one in which the trustees hold the assets and have a discretion about how to apply them. Rather than any particular person being entitled to a fixed share, the trustees can decide, within the terms of the trust, who benefits, when, and by how much.

In the context of disability planning, a discretionary trust is valuable because the disabled person has no fixed legal entitlement to the assets. This means that the assets held in the trust are generally not counted as the disabled person’s capital for the purposes of means-tested benefit assessments or local authority care funding calculations. The trust fund exists for their benefit, but it does not belong to them in the legal sense that would trigger those assessments.

Discretionary trusts are flexible. Alongside the disabled beneficiary, you might name other family members as potential beneficiaries, enabling trustees to respond to changing circumstances over time.

What Is a Disabled Person's Trust?

A disabled person’s trust (also known as a “disabled trust”) is a more specific arrangement that qualifies for preferential tax treatment under UK law. To qualify, the trust must be set up for a beneficiary who is “disabled” as defined by the relevant legislation. Broadly, this means a person who is incapable of managing their own property and affairs by reason of a mental disorder, or who receives a qualifying disability benefit.

Unlike a standard discretionary trust, a disabled trust is structured so that, during the disabled person’s lifetime, the trust’s income and capital must be applied primarily for the disabled person’s benefit. In practice, this means the trustees have less flexibility to benefit other family members during the disabled person’s lifetime, but the tax advantages can be significant.

The Tax Implications of Each Type of Trust

This is an area where the two types of trust differ meaningfully, and it is well worth understanding the distinction.

A standard discretionary trust is a “relevant property trust” for Inheritance Tax purposes. This means it is subject to a 20% Inheritance Tax charge when assets are placed into it (if the value transferred exceeds your available nil-rate band), a 10-year anniversary charge of up to 6% of the trust fund value, and exit charges when assets are paid out of the trust. Income within the trust is taxed at 45% (or 39.35% on dividends), and the trust has a small standard rate band of only £1,000.

A qualifying disabled person’s trust, by contrast, benefits from significantly more favourable treatment. It is treated as a “privileged trust” for both Inheritance Tax and Capital Gains Tax purposes. In practical terms:

  • Inheritance Tax: The trust is not subject to the 10-year anniversary or exit charges that apply to standard discretionary trusts. The assets are treated as if they remain part of the disabled person’s estate for IHT purposes.
  • Capital Gains Tax: The trust benefits from the full annual exempt amount available to an individual, and gains are taxed at the individual rates applicable to the disabled person rather than the higher trust rates.
  • Income Tax: The trust can elect to have income treated as the disabled person’s own income, potentially using their personal allowance and lower rate bands.

These advantages make the disabled person’s trust a very attractive option for beneficiaries who qualify. However, the requirements are specific, and the wording in your will needs to be carefully drafted to ensure the trust meets the statutory conditions.

Appointing Trustees for a Disabled Beneficiary

The choice of trustees is one of the most important decisions you will make when including a trust for a disabled person in your will. Trustees are the people who will actually manage the trust fund and decide how it is applied. Getting this right matters enormously.

What Makes a Good Trustee for a Disabled Beneficiary?

The most important quality in a trustee for a disabled person’s trust is not necessarily legal or financial expertise, although some understanding of both is certainly helpful. The most important quality is a genuine understanding of the disabled person’s needs, preferences, and circumstances.

A trustee who understands the person’s day-to-day life, their care requirements, their likes and dislikes, and how their condition affects them will be far better placed to make good decisions about the trust fund than someone who has only financial acumen and no real connection to the individual. This is particularly true where the beneficiary has complex care needs or communication difficulties.

Ideally, a trustee should be genuinely committed to acting in the disabled person’s best interests over the long term, as trust administration can span decades. They should have sufficient financial responsibility to manage the trust fund prudently and maintain proper records. They should also have sufficient understanding of the benefits system, or be willing to take advice on it, to ensure that the way the trust fund is applied does not inadvertently compromise the beneficiary’s entitlement to means-tested support. Finally, they should be someone who is likely to be available for the full duration of the trust, which is one reason why younger trustees are often preferable to older ones.

Professional Trustees and Trustee Companies

In some cases, it is appropriate to appoint a professional trustee alongside family members. A solicitor, accountant, or specialist trustee company can provide continuity and expertise, particularly where the trust fund is substantial or the beneficiary’s needs are complex. Professional trustees will charge for their services, so this needs to be factored into your planning.

It is also worth naming substitute or replacement trustees in your will, to provide for the possibility that your first choice of trustee may predecease you or be unable to act.

The Letter of Wishes

Alongside your will, it is strongly advisable to prepare a letter of wishes addressed to your trustees. This is a non-binding document in which you can explain your intentions in detail: the kind of lifestyle you hope the trust fund will support, specific needs or preferences the disabled person has, and any guidance you want to give about how to balance the interests of multiple beneficiaries. Although not legally binding, a well-written letter of wishes provides invaluable guidance and can prevent misunderstandings or disputes between trustees in later years.

Funding Long-Term Care for a Disabled Person

One of the most pressing practical concerns for parents and carers of a disabled person is how to fund their care needs in the long term. Care costs can be very substantial, particularly where someone requires residential or specialist care, and planning ahead through your will is one of the most meaningful steps you can take.

The Interaction Between Trust Funds and Local Authority Funding

Local authorities are required to fund care for people who meet certain eligibility criteria and whose financial resources fall below the means-test threshold. If a disabled person holds capital above that threshold, they will be expected to contribute to or fully fund their own care.

A properly structured discretionary trust or disabled trust can help preserve access to local authority funding, because the trust assets do not belong to the beneficiary in the way that would trigger a means-test assessment. The trustees can then use the trust fund to meet costs that the local authority does not cover, such as specialist equipment, additional therapies, holidays, or other items that enhance the person’s quality of life beyond what statutory provision offers.

This approach, sometimes described as “supplemental” or “topping up”, is one of the most practically valuable aspects of using a trust in this context.

Planning for Care Cost Inflation

It is important to bear in mind that care costs tend to increase over time, often significantly. When deciding how much to leave in trust for a disabled person, it is worth considering not only their current care needs but the likelihood that those needs will increase with age, and that the cost of meeting them will rise. Taking specialist advice on the likely long-term funding requirement is a sensible part of the planning process.

Life Insurance and Pension Planning

Some families use life insurance policies, written in trust, to provide an additional sum specifically earmarked for the disabled person’s long-term care. Similarly, it is worth reviewing your pension nominations. Pension funds that pass directly to a beneficiary outside your estate can be a tax-efficient way to fund care costs, although the interaction with means-testing needs careful consideration.

Frequently Asked Questions

Can I leave money directly to a disabled person in my will?

You can, but in many cases it is not advisable. If the person receives means-tested benefits or local authority care funding, an outright inheritance could reduce or remove that support. A discretionary trust, or disabled person’s trust, is usually a more effective way to provide for them without risking their existing entitlements.

A disabled person’s trust is a type of trust that qualifies for preferential tax treatment under UK legislation. To qualify, the beneficiary must be disabled as defined by the relevant law, generally meaning they lack the mental capacity to manage their own affairs or they receive a qualifying disability benefit. These trusts benefit from reduced Inheritance Tax charges and more favourable Capital Gains Tax treatment compared to standard discretionary trusts.

When properly drafted, a discretionary trust should not be counted as the disabled person’s capital for means-tested benefit purposes, because the disabled person has no fixed legal entitlement to the trust fund. However, the way in which trustees make payments from the trust can affect benefit entitlement in certain circumstances, so careful administration is essential.

The best choice is usually someone who knows the disabled person well and genuinely understands their needs, and who has the financial responsibility to manage the trust fund properly. Many families appoint a combination of a close family member and, where appropriate, a professional trustee to provide expertise and continuity.

Assets held in a properly structured discretionary trust or disabled person’s trust are generally outside the disabled person’s estate and should not be assessable for local authority means-testing. However, the rules in this area can be complex and fact-specific. Taking specialist legal advice when drafting the will is the most reliable way to ensure the trust achieves its intended purpose.

Yes. A trust can be structured so that trustees have the discretion to use the fund to meet care costs, either entirely or as a top-up, where the local authority is meeting some costs but not all. This can significantly improve the quality of care available to the disabled person throughout their life.

A letter of wishes is a document written by you to your trustees, explaining your intentions and giving guidance on how you would like the trust fund to be managed. It is not legally binding, but it is enormously helpful to trustees who will be making decisions over many years. It is strongly recommended whenever a trust is included in a will.

The key is to avoid leaving assets directly to the disabled person. Instead, consider leaving assets in a discretionary trust or a qualifying disabled person’s trust, with the disabled person named as a potential beneficiary. The trustees then apply the fund for their benefit, supplementing rather than replacing their benefit entitlements. A specialist will-drafting service can help you structure this correctly.
