At what age should you make an LPA?
Guidance from Estate Advisory Group

As soon as somebody else would struggle if you could not sign your name or make a decision yourself. For most people that is far earlier than they think — there is no minimum sensible age beyond 18.
There is no 'right' age in law
The Mental Capacity Act 2005 sets one age requirement for making an LPA: the donor must be 18 or over. There is no upper limit, and no suggested age at which people are expected to act. In practice, most people make their first LPA in their 50s, 60s or 70s, often prompted by a parent's own experience of managing without one — but that timing reflects habit rather than any legal or medical logic. Capacity, not age, is the only thing that matters, and capacity can be lost at any age, through an accident, a stroke, a brain injury or a sudden illness.
The real triggers
- You own a home, run a business or have dependants who would be affected if you could not act.
- You are the one who manages the household finances, so nobody else knows the accounts or passwords.
- You have a diagnosis, however early — see LPA after a dementia diagnosis.
- You are about to have surgery, or your work or hobbies carry physical risk.
- You travel or work abroad for long periods and want someone able to act in your absence as well as your incapacity.
Why waiting is the risk
Capacity is the only requirement, and it can go overnight
A stroke, a road accident or a sudden serious illness can remove the ability to make an LPA in a single day, at any age. After that, the only route left for your family is a Court of Protection deputyship — slower, more expensive, and supervised by the court rather than chosen by you. See what happens without an LPA.
A worked example
Jamie is 29, self-employed, and has just bought a flat with a mortgage in his sole name. He assumes LPAs are 'for old people' until a colleague is seriously injured in a cycling accident and spends six weeks unable to make decisions. Jamie realises that if the same happened to him, nobody could access his business account to pay contractors, or negotiate with his mortgage lender, without a lengthy Court of Protection application. He makes a financial LPA naming his sister as attorney and a health and welfare LPA naming his partner, both of which sit unused — he still manages everything himself — but which would let his family act immediately if he were ever unable to.
It sits unused until needed
A registered financial LPA can be restricted so it is only used once you lack capacity, and a health and welfare LPA can never be used while you can decide for yourself, whatever age you make it at. Making one at 30 costs you nothing in day-to-day control — you carry on making every decision yourself exactly as before. The document is simply there, ready, if it is ever needed.
How age affects the practicalities
| Age bracket | Typical situation | What to check |
|---|---|---|
| 18–30 | First mortgage, self-employment, travel | Attorneys are realistic — usually a parent or sibling |
| 30–50 | Children, a business, a bigger mortgage | Instructions cover business assets and dependants |
| 50–70 | Approaching retirement, ageing parents of your own | Replacement attorneys named in case a spouse is also affected |
| 70+ | Possible early health changes | Certificate provider is a GP or professional to record capacity clearly |
Making it easy to start
A common reason for putting an LPA off at any age is assuming it is a complicated, solicitor-only process. It is not: most people can complete both forms themselves, using a free eligibility check to confirm their choice of attorneys and certificate provider before spending any money, and an online LPA service to generate the paperwork with guided wording. Registration costs £92 per LPA regardless of the donor's age.
Common questions
Is 18 too young?
No. Anyone aged 18 or over with capacity can make one, and students studying or working abroad often do, precisely because a parent or sibling may need to act on their behalf while they are away.
Is 90 too late?
No, provided capacity is present at the time of signing. Consider a GP or solicitor as certificate provider to record the capacity assessment clearly, since applications from older donors sometimes attract extra scrutiny.
Should young, healthy people really bother?
Yes, if they have anything that would be hard for family to manage without authority — a mortgage, a business, dependants, or simply sole control of their own finances. Accidents and sudden illness are not limited to older age groups.
Does making an LPA young mean I have to keep the same attorneys forever?
No. You can make a new LPA at any point while you have capacity, naming different attorneys, and revoke the old one. See changing or cancelling an LPA.
