Planning for your child to outlive you: the hardest plan, and the most important

Who else knows which cup?

It is a stupid question and it is not a stupid question. Every SEND parent knows the small, unwritten operating instructions that make their child’s day work. The right cup. The order things have to happen in. The word that helps and the word that sets everything back an hour. None of it is written down anywhere, because it lives in your head and you have never needed it anywhere else.

Now ask the larger version. What happens to my child when I am no longer here?

Not in the ordinary sense, where parents eventually pass on and independent adult children get on with their lives. In the specific sense of a child who may need support for the whole of theirs, continuing long after the people who provided that support have gone.

It is the hardest plan a parent can make, because it asks you to sit with your own absence alongside your child’s continued vulnerability. It is also the most important, because the alternative to facing it is leaving the answer to chance. I have had to confront this myself, and I can tell you that facing it brings a kind of peace that avoiding it never does.

Why this is the central question

For families whose child will reach independence, the job has a natural endpoint. Get the child to adulthood and self sufficiency, then plan for your own later life.

For families whose child will need lifelong support, there is no endpoint. The support has to carry on beyond your life, which means it has to be built to outlast you.

That is what makes this the central question rather than one item on a list. Almost everything else in a SEND financial plan, the protection, the trust, the chosen people, the documented wishes, is in the end an answer to it. Get this right and the rest has a purpose. Avoid it and the rest has no foundation.

What an answer is made of

Several threads combine here, and they only really make sense pointed at this one question.

You need a structure, usually a disabled person’s trust, to hold and protect money for your child’s benefit without jeopardising means tested support. You need the right people: trustees to manage the money, and where relevant those responsible for care, chosen for the long term rather than for convenience. You need a letter of wishes, which is where the cup goes, and the routines, and everything else that currently exists only in your memory.

You need protection, and this is the element I would emphasise hardest, because it is what turns intention into something real. A great many plans quietly assume the parents live long enough to fund what is intended. The entire point of this planning is the scenario where they do not. If the money for your child’s lifelong support depends on your continued income, your early death undoes the plan at precisely the moment it was designed for. Appropriate life cover means the money exists regardless.

And you need all of it coordinated, so the will, the trust, the pension nominations and the protection are pointing the same way rather than quietly contradicting one another.

Individually those are tools. Aimed together at a single question, they become a plan.

What is on the far side

I will not pretend the process is anything other than emotionally hard. It asks you to imagine the unimaginable, and then to sit in an office with a form and make practical arrangements about it, calmly, on an ordinary Tuesday afternoon, as though it were any other piece of household administration. Parents defer it for that reason. I understand why.

But here is what I have seen, and what I have felt. On the far side of this planning there is relief, not more dread.

The worry a SEND parent carries about what happens to their child is at its heaviest while the question sits unanswered. Once there is a plan, the worry does not disappear, however it changes character. It stops being “what will become of them” and becomes “there is a plan”. That shift is worth more than almost anything else this work can give you.

You do not need everything figured out at once. You need to begin. One appointment, one conversation, one decision you have been circling for years and could settle in an afternoon, and then the trust, the people, the wishes and the protection, assembled steadily with proper advice. Not all of it. One thing.

Which brings me back to the cup. Somebody else will need to know about it one day, and they will only know if you tell them. So write it down, and then write down everything else, and then go and get the rest of it arranged while you have the time to do it properly.
