Understanding LPAs: The Complete Guide

Written by James Tyrrell · Reviewed by Anthony Dalton · Last reviewed 11 April 2026

A Lasting Power of Attorney is one of the most important legal documents you can create — yet most people put it off until it is too late. This guide explains everything you need to know about LPAs in plain language: what they are, why they matter, who needs one, and what happens if you do not have one. Whether you are 25 or 75, this is the place to start.

What Is a Lasting Power of Attorney?

A Lasting Power of Attorney (LPA) is a legal document that allows you to appoint one or more people you trust to make decisions on your behalf if you lose the mental capacity to make them yourself. The person making the LPA is called the "donor," and the people you choose to act for you are your "attorneys." Despite the name, your attorneys do not need to be lawyers — they can be family members, friends, or professionals.

LPAs are governed by the Mental Capacity Act 2005 and apply in England and Wales. Scotland and Northern Ireland have their own separate systems. To be valid, an LPA must be registered with the Office of the Public Guardian (OPG) before it can be used. You can only create an LPA while you still have mental capacity — if you wait until you have already lost it, it is too late.

There are two distinct types of LPA, and each covers a different area of your life. A Property and Financial Affairs LPA gives your attorney the authority to manage your money, pay your bills, deal with your bank, handle your investments, and make decisions about your property. This type can be used as soon as it is registered, even while you still have capacity — useful if you are physically unwell or simply want help. For a full explanation, see our Property and Financial Affairs LPA guide.

A Health and Welfare LPA covers decisions about your medical treatment, care arrangements, daily routine, and where you live. Unlike the financial LPA, this one can only be used when you lack the mental capacity to make the specific decision in question. It can also include the power to make decisions about life-sustaining treatment, but only if you specifically authorise this. Our Health and Welfare LPA guide covers this type in detail.

Most people should consider making both types. They cover completely different decisions, and having one does not replace the other. You can appoint the same attorneys for both, or choose different people depending on their strengths. For a clear comparison of the two, read our guide on the difference between Property and Financial Affairs and Health and Welfare LPAs. If you are new to all of this, our guide on what a Lasting Power of Attorney is is a good starting point.

Why You Need an LPA

The single most dangerous assumption people make is that their family will be able to step in and handle things if something happens. They cannot. In England and Wales, no one has an automatic legal right to manage your finances or make medical decisions for you — not your husband or wife, not your adult children, not your parents. This catches thousands of families off guard every year. Our guide on the myth that family can decide without an LPA explains why this belief is so widespread and so wrong.

Without an LPA, the only option is to apply to the Court of Protection for a deputyship order. This is the court-appointed alternative, and it is slow, expensive, and entirely outside your control. A deputyship application typically costs over £1,000 in court fees and legal costs, takes several months to process, and requires ongoing annual supervision fees. Worse, the court decides who acts for you — it might not be the person you would have chosen. Compare that to an LPA, which costs £92 to register and lets you choose exactly who acts for you and what powers they have. Our guide on why an LPA is cheaper than the Court of Protection breaks down the full cost comparison.

The financial consequences of not having an LPA can be severe and immediate. Bank accounts can be frozen. Direct debits and standing orders may stop. Mortgage payments can be missed. Bills pile up. If your partner relies on your income and cannot access your accounts, they may face genuine financial hardship within weeks. These are not hypothetical risks — they happen to real families every day. Read more in our guide on what happens without an LPA.

Financial commentator Martin Lewis has repeatedly urged people to set up LPAs, calling it one of the most overlooked pieces of financial planning. He has highlighted how the cost of an LPA is tiny compared to the cost and stress of a deputyship, and how putting it off is one of the biggest mistakes people make. Our guide on Martin Lewis and Power of Attorney summarises his key advice.

Many people also underestimate how an LPA compares to a will. A will only takes effect after you die. An LPA protects you while you are alive but unable to manage your own affairs. In many ways, an LPA is more urgent than a will because the situations it covers — strokes, accidents, dementia — can happen without warning and require immediate action. Our guide explains why a power of attorney is often more important than a will. For a full look at whether the cost is justified, see is an LPA worth it?

Who Should Get an LPA?

The short answer is: every adult in England and Wales. Anyone aged 18 or over with mental capacity can make an LPA, and the need for one is not limited to older people or those with health conditions. Mental capacity can be lost suddenly and unexpectedly at any age — through a road accident, a stroke, a brain injury, or a sudden illness. If it happens to you and you do not have an LPA, your family will face an expensive and stressful Court of Protection process at the worst possible time.

That said, certain groups of people have an especially strong reason to act. Parents of young children need to ensure their finances can be managed and their care preferences respected if they are incapacitated. Homeowners should know that without an LPA, nobody can manage their mortgage, sell their property, or make decisions about their home. Business owners face the risk of their business grinding to a halt if nobody has legal authority to act on their behalf. Our guide on who should consider making an LPA covers all of these situations in detail.

People with no close family have perhaps the greatest need for an LPA, because without one there may be no obvious person for the court to appoint as deputy. Those with existing health conditions — particularly conditions that may affect cognitive function over time — should act sooner rather than later, while they still have the capacity to make the document. But even if you are young and perfectly healthy, an LPA is one of the smartest pieces of planning you can do. See our guide: do I need an LPA if I am healthy?

Some people worry about the risks of giving someone else legal authority over their affairs. These concerns are understandable, but the safeguards built into the system — including the OPG's oversight role, the ability to add restrictions and instructions, and the Court of Protection's power to remove attorneys — mean that a well-made LPA is far safer than most people assume. Our guides on the risks of giving someone power of attorney and how safe an LPA is address these concerns honestly.

LPAs at Every Age

One of the biggest barriers to setting up an LPA is the belief that it is something you only need to think about when you are older. In reality, every stage of adult life brings its own reasons for having an LPA in place. The circumstances and priorities change, but the underlying need remains the same: if something happens to you, someone needs the legal authority to act.

More and more younger adults are now recognising this. The OPG has reported a steady increase in registrations from people under 50, driven by greater awareness of the risks of not having an LPA. Whether you are a university graduate just starting out, a parent juggling a mortgage and young children, or approaching retirement with a lifetime of assets to protect, there is a strong case for acting now. Our guide on why younger people are getting LPAs explores this trend, and our guide on the best age to set up an LPA gives a direct answer.

LPAs for Your Situation

Your personal circumstances can have a significant impact on how you set up an LPA, who you appoint as attorney, and what instructions you include. A business owner has very different needs from a retiree, and someone living abroad faces challenges that a UK resident does not. Understanding how your situation affects your LPA planning is important for getting it right.

Business owners need to think carefully about what happens to their business if they lose capacity. Without an LPA that specifically covers business decisions, nobody may have the legal authority to sign contracts, manage employees, or access business accounts. A standard Property and Financial Affairs LPA can cover business assets, but it is worth including clear instructions about how you want your business to be managed. See our guide on LPAs for business owners.

First-time homeowners should know that property ownership makes an LPA especially important. If you are incapacitated without one, nobody can manage your mortgage, pay your council tax, deal with repairs, or sell the property if needed to fund your care. Our guide on LPAs for first-time homeowners explains the specific risks and how to address them.

British citizens living abroad face the added complication that an English or Welsh LPA may not be automatically recognised in their country of residence. They may need both a UK LPA and a local equivalent. Our guide on LPAs for expats and British citizens abroad covers the key issues. Unmarried couples are in a particularly vulnerable position because the law gives them fewer automatic rights than married couples — making an LPA even more important. See LPAs for unmarried partners. And for those navigating separation, our guide on LPAs for divorced or separated couples explains what you need to review and update.

How LPAs Work in Practice

Understanding what an LPA is on paper is one thing. Knowing what actually happens when it needs to be used is another. Many people create an LPA and file it away without fully understanding how it will work in practice. The reality is that an LPA is a working document — when the time comes, your attorney will use it to interact with banks, healthcare providers, government agencies, and other organisations on your behalf.

For a Property and Financial Affairs LPA, your attorney will typically need to present the registered document (or a certified copy) to your bank and other financial institutions. Most major banks have dedicated teams for dealing with LPAs, and they will register the attorney's authority on your accounts. From that point, the attorney can manage your finances, pay bills, and handle transactions. The process is generally straightforward, though it can take a few weeks for banks to set up their systems. See our guide on how LPAs work in real life for practical details.

A Health and Welfare LPA works differently because it can only be used when the donor lacks capacity for a specific decision. Healthcare professionals will assess whether the donor can make the decision in question. If they cannot, the attorney steps in and works with the medical team to make decisions that reflect the donor's wishes and best interests. This might involve decisions about medical treatment, moving into a care home, or daily care arrangements. Our guide on how LPAs protect your future decisions explains this safeguard in more detail.

It is worth understanding exactly what an LPA allows and what powers an attorney has. The scope of authority depends on the type of LPA, any restrictions you have included, and the specific circumstances. The Mental Capacity Act and its principles underpin everything — decisions must be made in your best interests, and your attorney must always consider what you would have wanted.

Common Myths About LPAs

Misunderstandings about LPAs are widespread, and they stop thousands of people from taking action. Some of these myths are so deeply ingrained that people genuinely believe them, even though they are completely wrong. Let us set the record straight on a few of the most common ones.

"My family can make decisions for me anyway." This is the most dangerous myth of all. As we have already covered, nobody has any automatic legal right to manage your affairs, regardless of your relationship. Marriage does not grant it. Being next of kin does not grant it. The only things that grant it are an LPA or a Court of Protection order. See our full guide on the family can decide myth.

"My eldest child will automatically take charge." Another common belief with no basis in law. There is no legal principle that gives priority to the oldest child, or any child, when it comes to managing a parent's affairs. Without an LPA, the Court of Protection decides who acts — and it may not be the person you or your family would choose. Our guide on the myth that the oldest child automatically makes decisions debunks this thoroughly.

"LPAs are only for old people." Strokes, car accidents, brain injuries, and sudden illness do not discriminate by age. A 30-year-old who suffers a serious accident needs an LPA just as much as a 70-year-old with early dementia. The only difference is that the 30-year-old probably has not thought about it yet. Our guides on young adults and LPAs and whether you need an LPA if healthy address this directly.

"Making an LPA means giving up control." Creating an LPA does not mean handing over your life. You keep full control of everything for as long as you have mental capacity. A Health and Welfare LPA cannot even be used while you can make your own decisions. A Property and Financial Affairs LPA can technically be used while you have capacity, but only with your permission — and you can revoke it at any time. For a comprehensive myth-busting list, see our guide on LPA myths debunked.
