Because your autistic son has capacity, the legal machinery that surrounds many disabled adults simply does not apply to him. Nobody needs to be appointed to make decisions for him, because he makes his own. That is the reassuring half of the answer to what happens to your autistic son when you die. The harder half is that having capacity does not mean managing alone, and the daily support you give him — the prompts, the reminders, the forms, the phone calls, the quiet steadying presence — is invisible to every system that might otherwise step in.

This is the particular trap for a capable autistic adult. He is too able for the safeguards built around incapacity, and often too able to have ever been given a care package, yet the reason he manages at all is a parent doing a great deal, for free, every single day. When that parent is gone, none of it is automatically replaced. The council does not know it was happening. There is no file to reassign. The scaffolding just disappears.

So the useful thing this page can do is name that scaffolding, work out what it would cost to buy, and set out how to make sure the money to buy it actually exists and reaches the right hands. That is a planning problem with a real answer, not a fear you have to sit with.

At a glance

  • Because he has capacity, no deputy is needed. He makes his own decisions, and capacity is judged decision by decision.
  • Many capable autistic adults have no care package, because a parent quietly does the prompting, forms and organising instead.
  • The gap when you die is not usually a legal one. It is the unpaid daily support that has to be bought in or arranged.
  • Leaving money to him directly can breach the capital limits for means-tested benefits. A discretionary trust avoids that.
  • Because the need lasts his lifetime, cover that cannot expire before you do fits better than a term policy that stops at a set age.

The short answer: capacity settles the legal question, not the practical one

Capacity, in law, is the ability to make a particular decision at a particular time. Under the Mental Capacity Act 2005 in England and Wales, it is presumed unless shown otherwise, and it is decision-specific: someone can have capacity to decide where to live and how to spend money, while finding a different decision harder on a different day. Your son having capacity means the law treats him as the author of his own choices.

That closes off a whole set of arrangements you might have read about. He does not need a deputy appointed by the Court of Protection, because deputies exist only for people who cannot make a decision for themselves. He is not someone others can make decisions "in his best interests" for, because he makes them himself. In legal terms he is an ordinary adult, and that is exactly the point.

What he can do, while he has capacity, is choose to set up support for the future on his own terms. He could make a Lasting Power of Attorney, appointing someone he trusts to help with finances or welfare if he ever wanted or needed that later. That is his decision to make, not yours to make for him, but it is worth him knowing the option exists — because it is far easier to put in place calmly now than to arrange in a crisis.

Why he probably has no care package either

The second surprise is that capable autistic adults frequently have no social care at all — not because they need none, but because they were never assessed. A care package in England only follows a needs assessment under the Care Act 2014, in which the council decides whether someone has eligible needs it must meet. If nobody ever asked for that assessment, there is no package, no social worker and no record that support was ever required.

And often nobody asked, because a parent was quietly filling the gap. You made the appointments, chased the letters, sat through the calls, noticed when things were slipping. From the outside it looked as though your son needed nothing. The support was real; it just never had a name or a budget attached to it.

The single most useful thing you can do now is change that. Ask the council for a needs assessment for your son, so that his needs are documented while you are still here to describe them accurately, and ask for a carer's assessment for yourself as well. Getting him known to the system now means that when you die there is a starting point — a file, a named team, an assessed level of need — rather than a young man who has to prove from nothing that he needs help. When a carer dies, that assessment has to be revisited anyway, and it goes far better where one already exists; our guide on a care package built around the hours a parent-carer did unpaid follows exactly what that reassessment delivers and where it falls short.

The scaffolding you provide for free

It helps to make the invisible visible. Write down, honestly, everything you actually do for your son in a typical week. Most parents are startled by the list once it is on paper. It tends to include things like these.

  • Prompting and reminders — appointments, medication, meals, sleep, getting out of the house on time.
  • Managing correspondence and admin — opening post he finds overwhelming, dealing with bills, renewals, benefits letters and official forms.
  • Money management — helping budget, spotting when a subscription or a scam is draining the account, keeping direct debits on track.
  • Communication on his behalf — phone calls to services that use scripts and hold music he cannot tolerate, appointments where he needs someone to translate.
  • Transport and logistics — lifts, planning journeys, coming with him to unfamiliar places.
  • Emotional regulation — being the calm point when something has overloaded him, heading off a bad day before it becomes a bad week.

None of this shows up as "care" in the ordinary sense, and none of it stops being necessary because you are no longer there to do it. The bills in particular do not pause: when an account is frozen or a routine breaks, the direct debits carry on regardless, which is its own small avalanche, as our piece on a frozen account and the direct debits that keep going describes.

What that scaffolding costs, and who arranges it

Once the list exists, you can cost it, and this is the number that matters more than any other in your planning. Take the hours you spend each week on things that would have to be paid for — support worker time, a floating-support service, help with finances, transport — and price them against what providers in your area actually charge. That gives you a realistic weekly figure for buying in the support you currently give for nothing, and from there an annual one.

We deliberately do not put a national number on that here, because it depends entirely on his needs and your local prices, and a made-up figure would be worse than none. The exercise is to build your own from the real hours. Some of what you do may turn out to be met by a care package if he is assessed as eligible; the rest is what a family has to fund privately.

Who arranges it is the other open question. If there is no partner and no other parent, someone has to step into the organising role — a sibling, a trusted friend, or a paid support coordinator. It is worth deciding now who that is likely to be, asking them, and writing down how everything works so they are not starting blind. The wider question of who takes on that role, and how to prepare them, is the subject of our guide on who will look after an autistic son when a parent is gone.

Leaving money in a way that helps rather than harms

The instinct is to leave money straight to your son. For a capable autistic adult, that instinct can backfire in two ways, and both are avoidable.

The first is benefits. A direct inheritance becomes his capital, and if it pushes him above the capital limits for means-tested benefits, it can reduce or stop support he relies on — so a well-meant legacy quietly makes him worse off. The second is that managing a large lump sum may be one of the very things he finds hardest, which turns a gift into a burden.

The usual answer to both is a discretionary trust. Money held in a properly drafted discretionary trust is not counted as his capital, because no beneficiary has a fixed entitlement to it, so it is generally disregarded in a means test. Trustees you choose — people who know him — can release money for specific things, support hours, a laptop, help with a tenancy, without it landing in his account as savings. It keeps his benefits intact and takes the weight of managing a fund off his shoulders.

For the trust to help, it has to be funded, and this is where the type of life cover matters. You are the parent of an adult; you may well die at 80 or 90, long after an ordinary term policy would have ended. A policy that expired at 70 or 75 pays nothing if you die at 84 — which is exactly when this need lands — so the trust would be left empty. Cover designed to pay out whenever you die, rather than only within a fixed term, is the shape that matches a lifelong need, subject to the usual underwriting when you apply. If you want to understand how that could be structured and written into a trust for your son, you can get life insurance quotes and have an FCA-authorised broker set it up so the money reaches the trustees and not his benefit assessment.

One more thing to check while you are at it: make sure any pension or workplace benefit that pays out on your death is directed the right way too. These are usually paid at the discretion of a scheme, guided by a nomination form that is separate from your will and easy to forget — the same overlooked form we cover in the AVC pension with its own nomination you never signed. Pointing it at the trust rather than at your son personally keeps the whole plan consistent.

Scotland and Northern Ireland

The principle is UK-wide: a capable adult makes his own decisions, and a parent's unpaid support is not automatically replaced when they die. The legal frameworks around it differ.

In Scotland, capacity and any support for decision-making are governed by the Adults with Incapacity (Scotland) Act 2000, and social care runs under Scotland's own self-directed support system rather than the Care Act. In Northern Ireland, the Mental Capacity Act (Northern Ireland) 2016 and separate health and social care structures apply. The names of the assessments and the bodies that carry them out change; what does not change is the value of getting your son known to services now, choosing trustees, and funding a trust with cover that cannot run out before you do. You can read the wider set of situations these families face in our guide to dependants and unusual family shapes.

Frequently asked questions

My son has capacity, so does he need a deputy?

No. Deputyship is for people who cannot make a particular decision for themselves. Someone with capacity makes their own decisions and can choose to appoint an attorney under a lasting power of attorney if he wants support later. Capacity is decision-specific, so it can vary from one situation to another, but where he has it the law treats him as the author of his own choices.

Will he get a care package when I die?

Only if the council assesses him as having eligible needs under the Care Act 2014. Many autistic adults with capacity have never been assessed, because a parent quietly does the prompting, the forms and the phone calls. Request a needs assessment now rather than leaving it to a crisis, so his needs are documented while you are still here to describe them and there is a starting point for whoever picks things up.

Should I leave money to him directly?

A direct inheritance can push him over the capital limits for means-tested benefits, and managing a large sum may be one of the things he finds hardest. A discretionary trust with trustees who know him lets money be released for specific things without it counting as his savings, which protects both his benefits and his peace of mind. It needs to be funded, which is where life cover written into the trust comes in.
