Lasting Power of Attorney UK: A Guide for Families

Most families only think about a lasting power of attorney when something has already gone wrong: a parent has a stroke, a dementia diagnosis arrives, or the bank refuses to speak to anyone but the account holder. By then it can be too late to make one. This guide explains how a lasting power of attorney in the UK works (specifically in England and Wales, since Scotland and Northern Ireland have their own systems), what it lets you do, how to set it up properly, and how to talk about it with a parent without the conversation feeling like a takeover.

What a lasting power of attorney in the UK actually is

A lasting power of attorney (LPA) is a legal document in which a person, called the donor, chooses one or more trusted people, called attorneys, to make decisions on their behalf. The donor must be 18 or over and must have mental capacity when they make it, which means being able to understand, retain and weigh up the information and communicate a decision. It sits within the framework of the Mental Capacity Act 2005, whose starting point is that every adult is assumed to have capacity unless it is shown otherwise. An LPA is not a handover of control. It is a plan for the moment when the donor can no longer decide for themselves, chosen while they still can.

The two types: property and finance, health and welfare

There are two separate documents, and many families make both. They are registered separately and each carries its own fee. Understanding the difference matters, because they come into effect in different ways.

• Property and financial affairs: covers paying bills, managing bank accounts, collecting pension or benefits and, if needed, selling the family home to pay for care. The donor can choose to let it be used as soon as it is registered, with their permission, which is useful if a parent is still capable but finds paperwork tiring.
• Health and welfare: covers daily routine, medical care, where the person lives and, if the donor specifically allows it, decisions about life-sustaining treatment. It can only be used once the donor lacks capacity to make that particular decision.
• Attorneys can be appointed to act jointly (always together), jointly and severally (together or separately), or a mix depending on the decision. Replacement attorneys can be named in case one cannot continue.
• The donor can add preferences and instructions, for example that they would like to stay at home as long as it is safe, or that the attorneys must keep a particular property.

Life-sustaining treatment deserves a careful conversation. Under the Mental Capacity Act, a health and welfare attorney can only give or refuse consent to it if the document expressly says so. It is worth talking this through with the GP so that everyone understands what the choice means in practice.

How to make and register an LPA, step by step

You can use the online service on GOV.UK or the paper forms. Either way, everyone has to sign the same original printed document; copies and digital signatures are not accepted. A certificate provider must also sign to confirm the donor understands the LPA and is not being pressured. This must be someone aged 18 or over who has known the donor well for at least two years, or a professional such as their GP or a solicitor. Attorneys, family members and business partners cannot act as certificate provider. The donor can also name people to notify, who will be told about the application and can raise concerns before it is registered. Registration costs £92 per LPA, with reductions or exemptions for people on low incomes or certain benefits. The Office of the Public Guardian says registration takes 8 to 10 weeks if there are no mistakes, and errors in signing are the most common reason for delays.

• Agree who the attorneys and replacement attorneys will be, and talk to them first.
• Complete the forms, ideally together with your parent so the wording reflects their wishes.
• Sign in the right order: donor first, then the certificate provider, then the attorneys.
• Send the signed original to the Office of the Public Guardian with the fee or a fee remission request.
• Keep the registered document safe and know where certified copies are.

Capacity, dementia and why timing matters

From a medical point of view, capacity is decision specific and time specific. A person with mild cognitive impairment or early dementia may still have full capacity to make a lasting power of attorney, while being unable to manage complex investments. Capacity can also fluctuate: delirium caused by an infection, dehydration or a change in medication can temporarily cloud judgement in an older adult, and it often improves once the cause is treated. This is why geriatric teams talk about assessing capacity at the right moment rather than labelling a person once and for all. If your parent has a diagnosis, the earlier you start the better. If there is any doubt, ask the GP or a solicitor to act as certificate provider; their professional judgement adds protection for everyone. Our guide on how mild cognitive impairment differs from Alzheimer's explains what changes to watch for.

What happens if there is no LPA in place

If a parent loses capacity without a registered lasting power of attorney in the UK system of England and Wales, nobody automatically gains the right to manage their money, not even a spouse or adult child. The family usually has to apply to the Court of Protection to be appointed as a deputy. Deputyship is slower, involves court fees and annual supervision fees, requires yearly reports, and the court, not your parent, decides who is appointed. Joint bank accounts and informal arrangements rarely cover everything, especially when a house needs to be sold to pay for a care home. For health decisions, doctors will act in the person's best interests and should consult the family, but without an LPA relatives do not have the final say. In short, making an LPA early is far simpler than repairing the gap later.

Talking to a parent about it: autonomy, control and dignity

In psychogerontology, a sense of personal control is closely linked to wellbeing in later life. Older adults often face a series of losses (health, independence, friends), and a conversation about attorneys can feel like one more thing being taken away. That is why the framing matters. Present the LPA as a way for your parent to stay in charge: they choose who decides, they write down what matters to them, and they protect their wishes from being second guessed by strangers. Avoid raising it in a crisis or in front of the whole family. Choose a calm moment, start with a question (what would you want if you were ill and could not tell us?) and accept that it may take more than one conversation. Many people find it easier when the adult child mentions that they are making their own LPA too.

Being an attorney once a parent moves into a care home

Being an attorney is a responsibility, not a privilege. You must act in your parent's best interests, involve them in decisions as far as possible, keep their money separate from yours and keep records. When a parent lives in a care home, health and welfare decisions often arise in small, daily ways: a change of medication, appetite loss, a fall. Staying informed helps you make those decisions well. Palermia lets families see photos of their relative's day, check meals and medication as recorded by the home, and send direct messages to the care team, so an attorney is never deciding blind or chasing information by phone.

If you are just beginning to organise care for a parent, our caring for aging parents checklist helps you put legal, financial and practical steps in the right order. A lasting power of attorney in the UK is one of the first items on it for good reason: it costs little, takes a few weeks, and gives your parent a voice when they need it most. For individual circumstances, the Office of the Public Guardian, a solicitor or a local advice service can help.
