Who Becomes Your Son's Deputy When You Die?

You are your adult child's Court of Protection deputy. When you die, who becomes your disabled son's deputy in your place? The answer almost no page states plainly is: nobody. A deputyship does not pass to anyone. It ends the moment the deputy dies, and until someone new is appointed through a fresh application to the Court of Protection, there is no one with lawful authority to manage your child's money at all.

That is the gap families do not see coming. You spent years being the person who could operate the account, pay the care home, handle the benefits and sign for things — and the authority to do all of it was personal to you. It did not attach to your child, and it cannot be handed on like a baton. Someone has to go back to the court and be appointed afresh, and that takes months, during which the rent, the bills and the care charges keep arriving.

This page sets out what actually happens to a deputyship on death, how long the gap really runs, who applies next, and the part that quietly costs the most: when a professional steps in, the fees come out of your child's own money. It also covers what you can put in place now so the succession is planned rather than scrambled.

The short answer: nobody automatically replaces you

A deputy is someone the Court of Protection appoints to make decisions for an adult who lacks the mental capacity to make them alone, under the Mental Capacity Act 2005. Most deputyships are for property and financial affairs: operating bank accounts, collecting income, paying for care. The appointment is granted to a named individual — you — and it is that named individual the court has assessed and authorised. It is not a role that belongs to the family or to the person you look after.

Because it is personal to you, it dies with you. There is no provision by which your other child, or your spouse, or a sibling simply steps into your shoes. The bank will freeze what it was letting you operate. The authority that made you the decision-maker is gone, and no one holds it again until the court says so.

This is the single most important thing to understand, and it is why "who becomes deputy when I die" is not a question to leave for the family to work out later. Left unplanned, it means a period with nobody lawfully in charge of a vulnerable adult's finances — exactly when steady hands are most needed.

Why the role cannot simply pass on

It helps to see why the law is built this way rather than assuming it is an oversight. A deputy holds real power over someone who cannot protect themselves, so the court vets each deputy, sets the limits of what they can do, and supervises them through the Office of the Public Guardian. That protection would mean nothing if the authority could be passed privately from one person to the next without the court ever looking at the replacement.

So the safeguard that protects your child during your lifetime is the same feature that creates the gap after your death. The court has to assess whoever comes next, just as it assessed you. There is no shortcut, and there is no version where the role is written into your will and takes effect automatically — a will governs your estate, not your child's deputyship. If your planning also involves who physically cares for your son and how their household is supported, that sits alongside the money question in how trustees can fund the home a carer is running.

The gap: months with nobody in charge

A new deputyship application is not a quick form. It involves an assessment of the person's capacity, detailed information about their finances, and the court's own process, and it is realistically measured in months. Where anyone objects, or the court wants more evidence, it runs longer.

Meanwhile, nothing about your child's life pauses to wait for it. The supported-living rent is due. The care provider invoices as normal. Council tax, utilities and everyday costs carry on. If the only person who could lawfully pay them has died and no one has yet been appointed, direct debits can fail and arrears can build against someone who has done nothing wrong and cannot act for themselves. In urgent cases the court can be asked to make an interim or emergency order, but that too takes an application and time. The practical lesson families take from this is to make sure some money is reachable to keep the essentials paid while the new deputyship is sorted — which is really a question of what you leave behind and how, the theme of arranging cover that has to outlive you for a lifelong dependant.

Plan the succession before it is needed

You cannot name a successor deputy in your will, but you are not powerless. The Court of Protection can appoint more than one deputy, and it can appoint them to act in different ways: jointly, jointly and severally, or one after another. That opens two practical routes worth discussing when the deputyship is first set up, or by applying to vary it now.

The first is a joint or joint-and-several deputyship — for example you and your other adult child, or you and a trusted relative, appointed together. If one of you dies, a co-deputy who is appointed to act severally can carry on, avoiding the total gap. The second is asking the court to appoint a successor who steps up when the first can no longer act. Which is appropriate depends on your family, and it is exactly the kind of thing to plan while you are well rather than in a crisis, as the harder version in facing a terminal diagnosis when your son has no deputy in place makes painfully clear. The government's guidance on how to apply to become a deputy sets out the current process and forms.

Two other steps make the eventual handover far smoother. Keep an organised record of your child's income, benefits, accounts, care arrangements and key contacts, so whoever applies next is not starting blind. And take advice on holding an accessible fund — often through a suitable trust — so money can keep the essentials paid during the months before a new deputy is in place.

It is worth telling your own executors one more thing, because it surprises the family that has to deal with it. When a deputy dies, the deputyship has to be formally wound up: your executors must notify the Office of the Public Guardian and, in most cases, submit a final report or account covering your time as deputy up to the date of death. In other words, being a deputy leaves a loose end that your estate has to tie off, on top of everything else your family is handling. Leaving clear records and telling your executors where they are turns that from a distressing scramble into a straightforward task, and it means the transition to the next deputy is not held up by missing paperwork.

What a professional deputy costs, and who pays

If no family member is able or willing to take over, the court can appoint a professional: a solicitor, or the local authority's deputyship team. This can be the right answer, and sometimes the only one. But it is important to understand who pays for it, because the answer is your child.

A professional deputy is remunerated from the funds of the person they act for, at rates the court authorises, and there is an annual supervision fee payable to the Office of the Public Guardian on top. None of this comes out of the professional's pocket or the state's — it is deducted from your child's own money, year after year, for as long as the deputyship continues. Over the decades a young disabled adult may live, that steady deduction adds up to a meaningful slice of whatever you leave. The exact fees are set by the government and change from time to time, so check the current figures rather than working from an old number; but the principle does not change, and it is a strong reason to consider whether a willing family deputy, properly planned, would preserve more of the fund for actual care.

The fund that has to outlive you

Behind the legal machinery is a simple financial fact: your disabled child may outlive you by decades, and the money that supports them has to stretch across all of it. Whatever cushions the gap after your death, pays professional fees if it comes to that, and tops up care over a long life, has to be there because you put it there.

This is the situation whole-of-life cover is built for. Unlike a term policy that ends on a set date, whole-of-life cover is designed to pay out whenever you die, which is what you need when the dependant outlives you rather than the other way round. How the money is held matters as much as the fact of it: capital in your child's own name can reduce means-tested benefits and count towards care charges, whereas a suitable trust lets trustees spend on your child's behalf without the fund being treated as theirs. That structure needs proper advice — an FCA-authorised broker can help with the cover and a solicitor with the trust — and you can begin by using life insurance quotes to see what leaving a lasting fund would involve. If the person you care for lives in social housing, there is a separate question worth checking about whether your son can take over the council tenancy when you die, because keeping the roof stable is part of the same plan.

Scotland and Northern Ireland

The role has different names around the UK, but the succession problem is the same everywhere: the authority is personal, and it ends when the person holding it dies.

Scotland does not use deputyship. Financial decisions for an adult without capacity are handled through a financial guardianship or an intervention order under the Adults with Incapacity (Scotland) Act 2000, appointed by the sheriff court and supervised by the Office of the Public Guardian (Scotland). A guardianship ends on the guardian's death, and a fresh application is needed — so families there often ask for joint guardians for the same reason. Northern Ireland has historically used a controller appointed through the Office of Care and Protection, with its own supervision. In each jurisdiction the safeguard is the same, and so is the gap it creates on death, which is why planning the succession in advance is the common thread wherever you live.

Frequently asked questions

Who becomes deputy when the existing deputy dies?

Nobody automatically. A deputyship ends on the deputy's death and a fresh application must be made to the Court of Protection. Until it is granted, no one is lawfully able to manage that person's finances, which is why families plan the succession in advance, often by asking the court to appoint joint or successive deputies from the start.

How long does a new deputyship application take?

Court of Protection applications are measured in months rather than weeks, and take longer where anyone objects or further evidence is required. Rent, bills and care charges carry on throughout, so families often keep an accessible fund, frequently through a trust, to cover the gap while the new deputy is being appointed.

What does a professional deputy cost?

A solicitor or local authority deputy is paid from the person's own funds at rates the court authorises, plus the annual supervision fee payable to the Office of the Public Guardian. The exact amounts are set by the government and change over time, but across decades that steady deduction becomes a substantial reduction in the money left for care.
