Most people plan for what happens after they die through a will, but far fewer plan for something arguably more likely: a period when they are still alive but unable to make decisions for themselves. An accident, a stroke or a condition such as dementia can leave anyone, at any age, temporarily or permanently unable to manage their own affairs. A power of attorney is the legal tool that prepares for exactly that. This guide explains what it is, the types available in the UK, how to set one up, and why it is worth doing before you think you need it. This is general information, not legal advice.

What a power of attorney is

A power of attorney is a legal document that lets you — the "donor" — appoint one or more people you trust, your "attorneys", to make decisions on your behalf. The most important kind for planning ahead is a lasting power of attorney (LPA), which is specifically designed to keep working if you later lose the mental capacity to make decisions yourself.

This makes an LPA the natural companion to a will. A will deals with your estate after death; an LPA deals with your affairs while you are alive but unable to manage them. Together they form a complete plan, and our guide to making a will covers the other half. Just as you would not leave your savings or pension without a plan, leaving the question of "who decides if I can't?" unanswered creates real problems for the people around you.

The two types of LPA

In England and Wales, there are two separate lasting powers of attorney, and you can make one or both:

  • Property and financial affairs LPA. This covers money and property — managing bank accounts, paying bills, collecting income and benefits, dealing with investments, and selling a home. With your permission, it can be used while you still have capacity (for example if illness makes day-to-day admin hard), as well as if you lose it.
  • Health and welfare LPA. This covers decisions about your care — medical treatment, where you live, daily routine, and, if you specify it, decisions about life-sustaining treatment. It can only be used once you have lost the capacity to make these decisions yourself.

You can appoint different attorneys for each, and choose whether multiple attorneys must act jointly (all decisions together) or jointly and severally (able to act independently).

Choosing attorneys is the heart of the decision. These are people who may one day handle your money or your medical care, so trustworthiness, good judgement and a willingness to take it on matter far more than convenience.

Scotland and Northern Ireland have their own, different systems (for example continuing and welfare powers of attorney in Scotland), so check the rules for where you live.

Why an LPA matters

The most common and costly misconception is that a husband, wife or close relative can automatically step in. They cannot. Losing capacity without an LPA in place does not hand control to your next of kin — it leaves a gap that only a court can fill.

Without an LPA, loved ones usually have to apply to the Court of Protection to be appointed as a deputy. Compared with an LPA, that route is:

  • Slower — it can take many months, during which bills and care decisions may be stuck.
  • More expensive — with application fees and often ongoing supervision costs.
  • More restrictive — a deputy's powers are limited and supervised by the Office of the Public Guardian.
  • Out of your hands — the court, not you, decides who is appointed.

A simple comparison:

Setting up an LPA in advance is the difference between your chosen person being able to act quickly and your family facing a stressful, costly legal process during a crisis.

How to set up an LPA

The process in England and Wales is designed to be done without a solicitor, though advice helps for complex situations.

  1. Choose your attorney(s). Pick people you trust completely, and consider naming a replacement in case an attorney can no longer act.
  2. Decide the details. Whether attorneys act jointly or jointly and severally, any preferences or instructions you want to include, and (for health and welfare) your wishes on life-sustaining treatment.
  3. Complete the LPA forms. You can do this online or on paper via the GOV.UK service. A certificate provider — an independent person — must confirm you understand the LPA and are not under pressure.
  4. Sign and witness the forms in the correct order; getting the sequence wrong is a common reason applications are rejected.
  5. Register with the Office of the Public Guardian (OPG). An LPA must be registered before it can be used, and registration takes several weeks. There is a fee, with reductions or exemptions for those on low incomes.

Because registration takes time, the golden rule is to set up an LPA while you are well, long before it might be needed. You cannot make an LPA once you have already lost capacity — at that point only the Court of Protection route remains.

Common questions and pitfalls

  • Can I still make my own decisions? Yes. Having an LPA does not take away your right to decide while you have capacity; it is a safeguard for if and when you cannot.
  • Can I cancel it? Yes, you can revoke an LPA while you still have capacity.
  • Do attorneys have to follow rules? Yes — they must act in your best interests, follow the principles of the Mental Capacity Act, and keep your money separate from their own. The OPG can investigate concerns.
  • What about my pension and accounts? A property and financial affairs LPA lets your attorney manage these, which is why it pairs naturally with keeping your wider finances — including any emergency fund — clearly organised and documented.

For free guidance, Citizens Advice and the Office of the Public Guardian are reliable starting points, and GOV.UK hosts the official forms and detailed rules.

The bottom line

A lasting power of attorney lets someone you trust step in to manage your finances or your health and welfare if you ever lose the capacity to do so yourself — and it is the only way to keep that choice in your own hands. Without one, your loved ones face the slow, costly Court of Protection process at the worst possible moment. There are two types in England and Wales, both needing registration before use, so the key is to set one up while you are well rather than waiting. Treat it as the living-side companion to your will, and for anything complex, take proper legal advice.

Frequently asked questions

What is a power of attorney?

It is a legal document that lets you (the 'donor') give one or more people you trust (your 'attorneys') the authority to make decisions on your behalf. A lasting power of attorney is designed to keep working if you later lose the mental capacity to decide for yourself. This is general information, not legal advice.

What are the two types of LPA?

In England and Wales there are two: a property and financial affairs LPA, covering things like bank accounts, bills and selling a home; and a health and welfare LPA, covering medical care, where you live and day-to-day welfare. You can make one or both, and choose different attorneys for each.

Do I have to register an LPA?

Yes. A lasting power of attorney must be registered with the Office of the Public Guardian before it can be used. Registration takes some weeks, so it is best set up well before it is needed rather than in a crisis.

What happens if I don't have an LPA and lose capacity?

Nobody automatically gets the right to manage your affairs — not even a spouse. Loved ones would usually have to apply to the Court of Protection to become a 'deputy', which is slower, more expensive and more restrictive than having an LPA in place.
