Your disabled child may outlive you by decades. That is the sentence most parents carrying this worry never quite let themselves finish, and it is the one that has to be finished before anything useful can be planned. The care and money you provide now will one day have to be provided by someone else, or by something you set up in advance, for all the years of your child's life that fall after your own.
The honest first step is not reassurance. It is arithmetic. Turn the fear into two numbers: how many years your child is likely to live after you are gone, and what has to be paid for across those years. Once the gap between your life and theirs is an actual number of years rather than a vague dread, the funding question stops being unanswerable and becomes a plan you can build, fund and write down.
This page works through both numbers, then through the parts that have to be funded, the way to hold the money so it does not do more harm than good, who makes the decisions once you cannot, and the kind of life cover that does not run out before the need does.
At a glance
- Start by estimating the gap in years between your likely lifespan and your child's. For many families it is measured in decades.
- Three things have to be funded across those years: somewhere to live, support and care hours, and everyday money.
- Leaving money to a disabled child in their own name can reduce means-tested benefits and increase care charges.
- A discretionary or disabled person's trust lets trustees pay for things without the fund counting as the person's own capital.
- Because the need is lifelong, cover that can expire before you die may leave nothing behind. Whole-of-life cover is designed to pay out whenever death comes.
Put a number on the years
The plan starts with the gap. Take your own age and your child's, and think honestly about how long each of you is likely to live. Many people now live well into their eighties, and for a great many disabilities life expectancy has moved much closer to the general population than it once was, so planning has to assume your child could live a full adult life. The Office for National Statistics publishes the standard reference for how long people live at each age, and it is the right place to run your own version of this sum rather than guess.

Make it concrete with a worked example. Suppose you are 45 and your child is 15. If you live into your early eighties and your child lives into their seventies, then your child faces something like fifty-five more years of life, of which roughly forty fall after you are gone. That is forty years of housing, support and money to account for. Change the ages and the gap changes, but for most parents asking this question the answer lands somewhere between thirty and fifty years. Writing that number down is uncomfortable, and it is also the moment the problem becomes finite and therefore solvable.
The point of the number is not to frighten you further. It is to stop you planning for the wrong horizon. Cover and savings sized to see a child to 18, or to see you to retirement, do not stretch across a gap like that, which is the mistake this whole topic exists to prevent, set out from the other direction in cover that has to outlive you after a diagnosis.
What actually has to be funded across those years
Once you have the years, break the requirement into three parts, because they behave very differently and are paid for from different places.
The first is somewhere to live. When you are no longer there, your child needs a settled home, whether that is a supported living tenancy, a place in a shared arrangement, staying in the family home with support brought in, or living with a sibling or another relative. Housing is the piece families most often assume will simply carry on, and the piece that most often does not without money and planning behind it.
The second is support and care hours. This is the day-to-day help your child needs, from a little prompting to round-the-clock care depending on the condition. Some of it may be met by the local authority following an assessment, but assessed support is rarely everything a parent was quietly providing for free, and the gap between what a council funds and what your child actually needs is real. Care can carry a substantial weekly cost, and across the decades you have just counted, that adds up to the largest single call on any plan.
The third is everyday money: the ordinary spending that makes a life rather than a bare existence, clothes, a phone, days out, a holiday, birthday presents, the things a parent hands over without thinking. Benefits and care funding rarely stretch to any of this, and it is usually what the money you leave is really for. Whoever ends up closest to your child, and whether they can afford to be involved, matters enormously here, which is why the question of whether the person taking over can actually afford it belongs in the plan from the start.
Why leaving money to your child directly can backfire
The instinct is to leave your disabled child a generous share of your estate outright, the same as you would any child. For a disabled child who relies on means-tested support, that instinct can quietly do harm.
Most social care and several key benefits are means tested against the person's own capital and income. Money left directly to your child becomes their capital. Above the relevant thresholds it can reduce or remove means-tested benefits and increase what they are charged for their care, so a well-meant lump sum can end up substituting for support they would otherwise have received rather than adding to it. In the worst version, the inheritance is slowly consumed by care charges that the state would have covered had the money been held differently, and your child is no better off for what you left.
The problem is not the amount. It is the ownership. Capital sitting in your child's own name counts against them; the same capital held for their benefit by someone else, on the right terms, generally does not. That single distinction is the hinge the whole plan turns on.
The trust that holds it instead
The usual answer is to leave the money not to your child but to a trust for your child. Trustees hold and control the fund and make payments for your child's benefit, which means the capital is not your child's to be counted, but the money is still there to be spent on them.
Two forms come up most. An ordinary discretionary trust gives trustees complete discretion over what to pay and when, which keeps the fund flexible and outside your child's means-tested capital. A disabled person's trust, for a beneficiary who meets HMRC's definition of a disabled person, works on the same principle but is taxed more favourably than an ordinary discretionary trust, at the cost of tighter rules about who benefits. Which fits depends on your child's circumstances and is a question for a solicitor who does this work, not a decision to make from a template.
Either way, the trustees are the people who make it work, so choose them as carefully as the structure. They will manage money and make judgements for potentially decades, so you want people who will still be around, or a mechanism to replace them as they age or step down, and ideally a mix that includes someone who knows your child well and someone with a steady hand for money. Naming, say, grandparents who are themselves getting older carries a built-in expiry, a trap we cover in naming grandparents in their seventies, so build in successors from the outset. A letter of wishes alongside the trust, describing your child's routines, likes, needs and the life you want funded, is what lets trustees who never knew your child as you did still spend the money the way you would have.
Who makes the decisions when you are gone
Money is only half of it. Someone also has to make decisions, and who that is changes as your child grows.
While your child is under 18, you can appoint a guardian in your will to take over their care. That guardian handles day-to-day upbringing, though not the trust money if you have sensibly kept the roles separate. If the person you have in mind lives overseas, be aware there are real practical hurdles to sort out first, as we explain in what a guardian living abroad has to do.
Once your child is an adult, guardianship no longer applies, and decisions fall under the Mental Capacity Act 2005. If your child has the capacity to make a lasting power of attorney, they can appoint someone they trust to help with decisions; if they do not, someone may need to apply to the Court of Protection to be made a deputy for their property and affairs, and sometimes for welfare. This is a separate step from the trust and from your will, and it is worth putting in hand rather than leaving for whoever is left to discover. Alongside all of this, the local authority has a duty under the Care Act 2014 to assess your child's needs once it knows of them, and support flows from that assessment, so making sure the council is engaged early is part of the handover. The urgency of getting these pieces in place is sharpest for a lone parent, which is why we deal with it directly in funding the guardian after a single parent's terminal diagnosis.
Cover that does not expire before the need does
Here is where the number of years you wrote down at the start decides the product. A lifelong need cannot be met by cover that stops.
Ordinary term life insurance runs for a fixed number of years, twenty or twenty-five, say, and pays out only if you die within that term. It is the right tool for a mortgage or for raising children to independence, because those needs have an end date. Your disabled child's need does not. If your term cover ends at 65 and you live to 84, it pays nothing, and the fund you were relying on to seed the trust never arrives. Cover designed for a need that never ends has to be able to pay out whenever you die.
That is what whole-of-life cover is built for. It has no fixed end date and is designed to pay a sum whenever death occurs, which is why it is the cover most often used to fund a trust for a lifelong dependant. Whether an insurer offers it, and on what terms, depends on your health and is a matter for underwriting rather than anything that can be promised in advance, and how it is structured and sized should be worked out against the funding number you calculated, not picked off a shelf. An FCA-authorised broker can price it against your circumstances and, crucially, arrange for it to be written in trust so the payout goes straight to the trustees rather than into your estate. If you want to see what that would involve for your family, you can get life insurance quotes and have it set up to pay into the trust from day one. For the wider set of will, guardianship and trustee decisions this connects to, our guide to wills, guardianship and children pulls them together.
Scotland and Northern Ireland
The strategy, hold the money in trust and make sure it can pay out for as long as your child lives, holds across the UK, but some of the surrounding law differs.
In Scotland, adult welfare and financial decisions sit under the Adults with Incapacity (Scotland) Act 2000 rather than the Mental Capacity Act, so the equivalent of a deputy is a guardian or intervener appointed through the sheriff court, and the powers of attorney work under Scottish rules. Social care duties run through Scottish legislation and its own assessment process. The trust principles are broadly similar, but a will and trust for a Scottish family should be drafted under Scots law.
Northern Ireland has its own framework again, with its own mental capacity legislation and its own health and social care structures, so the decision-making routes and the assessment process differ from those in England and Wales. Wherever you are, the core aim is the same: money held so it does not count against your child, cover that lasts as long as they might, and named people with the legal authority to act once you no longer can.
Frequently asked questions
Who pays for my disabled child's care after I die?
Funding normally comes from a mix: local authority social care following a Care Act 2014 assessment, disability benefits, and whatever you leave. Council support is means tested against the person's own capital, so how you leave money matters as much as how much you leave. A trust that holds the money for your child, rather than a gift into their own name, keeps your provision from simply displacing the support they would otherwise receive.
Should I leave money to my disabled child directly?
Often not. Capital held in their own name counts for means-tested benefits and care charging, so a direct gift can reduce the support they receive and be eaten up by care charges the state would otherwise have met. Many families use a discretionary trust or a disabled person's trust instead, letting trustees pay for things for the child's benefit without the fund counting as the person's own capital.
What is a disabled person's trust?
It is a trust for a beneficiary who meets HMRC's definition of a disabled person, taxed more favourably than an ordinary discretionary trust. Trustees keep control of the capital and make payments for the beneficiary's benefit rather than handing money over as income, which protects means-tested support. Whether it suits your child, or a plain discretionary trust fits better, is a question for a solicitor who does this work.
