Losing mental capacity can be a distressing experience for individuals and their loved ones. Whether caused by dementia, stroke, brain injury, or age-related decline, the inability to make decisions for yourself creates immediate and serious practical problems.
When someone loses the ability to make decisions for themselves, it can create significant challenges for their family and friends. Without a Lasting Power of Attorney (LPA) in place, the process of managing their affairs becomes complicated, expensive, and often requires Court of Protection intervention — a process that can take months and cost thousands of pounds.
At MP Estate Planning, we believe in planning ahead — because the time to prepare for mental capacity loss is while you still have the capacity to do so. Having a Lasting Power of Attorney in place provides peace of mind, knowing that people you trust will be legally empowered to make important decisions on your behalf if needed. As Mike Pugh puts it: “Plan, don’t panic.”
Key Takeaways
- Losing mental capacity without an LPA means your family has no automatic legal authority to manage your affairs — even your spouse cannot access your sole bank accounts.
- A Lasting Power of Attorney (LPA) is essential for ensuring your chosen people can manage your finances and healthcare decisions.
- Without an LPA, your family must apply to the Court of Protection for a deputyship order — a process that typically takes 4-6 months and costs significantly more than setting up an LPA.
- Having an LPA in place provides immediate legal authority and avoids delays, disputes, and unnecessary court involvement.
- You can only make an LPA while you still have mental capacity — once capacity is lost, it is too late.
Understanding Mental Capacity in the UK
Mental capacity is a crucial concept in English and Welsh law, particularly when it comes to planning for the future through instruments like a Lasting Power of Attorney. It refers to a person’s ability to make a specific decision for themselves at the time it needs to be made.
Definition of Mental Capacity
Mental capacity is defined under the Mental Capacity Act 2005 as the ability to make a particular decision at the time it needs to be made. This involves understanding, retaining, and weighing information relevant to the decision, and then communicating that decision by any means.
To have mental capacity for a particular decision, an individual must be able to:
- Understand the information given to them that is relevant to the decision
- Retain that information long enough to make a decision (even if only briefly)
- Weigh up the information available — including the consequences of deciding one way or another, or of not making the decision at all
- Communicate their decision by any means, including talking, sign language, or even blinking
Legal Framework Surrounding Mental Capacity
The Mental Capacity Act 2005 provides the legal framework for mental capacity in England and Wales. This Act ensures that individuals who lack mental capacity are protected and that their best interests are considered when decisions are made on their behalf.
The Act is underpinned by five key principles:
- A person must be assumed to have capacity unless it is established that they lack capacity.
- Individuals should be given all practicable help and support to make their own decisions before anyone concludes they lack capacity.
- A person has the right to make what might be seen as an unwise decision — an unwise decision does not mean someone lacks capacity.
- Any decision made on behalf of someone who lacks capacity must be in their best interests.
- The decision made should be the least restrictive option available, minimising interference with the person’s rights and freedoms.
Assessment of Mental Capacity
Assessing mental capacity involves determining whether an individual can make a specific decision at the time it needs to be made. This assessment is both decision-specific and time-specific — someone may have capacity to decide what to eat for lunch but lack capacity to manage complex financial affairs.
The assessment follows a two-stage test. First, does the person have an impairment of, or disturbance in the functioning of, the mind or brain? Second, if so, does that impairment or disturbance mean they are unable to make the specific decision at the time it needs to be made?
| Assessment Criteria | Description |
|---|---|
| Understanding | Can the person understand the information relevant to the decision? |
| Retention | Can the person retain the information long enough to make a decision? |
| Weighing Information | Can the person use or weigh the information to make a decision? |
| Communication | Can the person communicate their decision by any means? |
Understanding mental capacity is essential because it directly affects your ability to plan for the future. A person creating a Lasting Power of Attorney must have the mental capacity to understand what they are doing at the time the LPA is made. This is why early planning is so important — once capacity is lost, the window to create an LPA closes permanently.
The Importance of a Lasting Power of Attorney
A Lasting Power of Attorney (LPA) is a vital legal document that ensures your wishes are respected if you lose mental capacity. It allows you to appoint someone you trust — your “attorney” — to make decisions on your behalf, ensuring that your affairs are managed according to your preferences rather than being left to the courts.
Types of Lasting Power of Attorney
In England and Wales, there are two types of Lasting Power of Attorney (LPA), each covering different areas of your life. Both remain in effect even after you lose mental capacity — that is their entire purpose.
Property and Financial Affairs LPA — This allows your attorney to manage your bank accounts, pay bills, collect your state pension or benefits, sell or rent your property, and deal with your tax affairs through HMRC. Importantly, this type of LPA can be used while you still have capacity (with your consent), making it useful for managing affairs if you become physically unable to get to the bank, for example.
Health and Welfare LPA — This gives your attorney the authority to make decisions about your medical treatment, where you live, your daily care routine, and — if you specifically authorise it — decisions about life-sustaining treatment. This type of LPA can only be used once you have lost mental capacity to make the specific health decision in question.
We strongly recommend having both types of LPA in place. If you only have a Property and Financial Affairs LPA, your attorney cannot make healthcare decisions on your behalf, and vice versa.
Benefits of Having a Lasting Power of Attorney
Having an LPA provides numerous concrete benefits, particularly if you lose mental capacity:
- Immediate authority: Your chosen attorneys can act straight away once the LPA is registered, without needing court permission. Compare this with the deputyship process, which typically takes 4-6 months.
- Your choice of decision-maker: You decide who manages your affairs — not the court. You can appoint family members, trusted friends, or professionals.
- Lower cost: Setting up an LPA costs a fraction of a deputyship application, and there are no ongoing annual supervision fees from the Office of the Public Guardian (unlike deputyship).
- Your wishes are recorded: You can include specific preferences and instructions in the LPA, guiding your attorneys on how you want decisions to be made.
- Reduced family stress: Your loved ones are not left with the burden of navigating the Court of Protection during what is already an emotionally difficult time.
By setting up a Lasting Power of Attorney, you avoid the costly and time-consuming deputyship process that English and Welsh law requires when someone lacks mental capacity without a designated attorney. The Court of Protection application alone involves court fees, solicitor costs, and ongoing annual supervision charges — all of which can be avoided with proper planning.
Consequences of Losing Mental Capacity Without a Lasting Power of Attorney
Without a Lasting Power of Attorney, losing mental capacity can result in your family having to navigate complex and expensive legal procedures to gain authority to make even basic decisions on your behalf. This can lead to significant delays, family disputes, and additional stress during an already challenging time.
Default Legal Procedures
If you lose mental capacity and don’t have an LPA in place, your loved ones must apply to the Court of Protection to be appointed as your deputy. This is not a quick or simple process. It involves completing detailed application forms, providing medical evidence of your incapacity, notifying relevant family members (who can object), paying court fees and potentially solicitor costs, and waiting for the court to process the application.
The deputyship application process typically takes 4-6 months, and in contested cases it can take considerably longer. During that entire period, nobody has legal authority to manage your affairs — your bank accounts remain frozen, your bills may go unpaid, and important decisions about your care cannot be made by your family.
| Procedure | Description | Potential Challenges |
|---|---|---|
| Application to Court of Protection | Filing detailed paperwork, medical evidence, and a deputyship plan to be appointed as deputy | Complex forms, court fees (currently several hundred pounds), solicitor costs, and a waiting period of 4-6 months or more |
| Notification of Family Members | All close family members must be notified of the application and given the opportunity to object | Family disagreements and objections can delay the process significantly and lead to contested hearings |
| Ongoing Supervision and Reporting | Deputies must submit annual reports to the Office of the Public Guardian and pay an annual supervision fee | Ongoing administrative burden, costs, and the requirement to seek court approval for certain decisions (such as selling property) |
Impact on Financial Affairs
Losing mental capacity without an LPA can have an immediate and severe impact on your financial affairs. Banks and building societies will freeze your sole-name accounts as soon as they become aware you have lost mental capacity. This means nobody can withdraw money to pay your mortgage, council tax, utility bills, or care fees until a deputy is appointed — a process that, as we’ve noted, takes months.
Your loved ones cannot access your savings, manage your investments, deal with HMRC on your behalf, or sell your property without legal authority. Even joint account holders may find that the bank restricts what can be done on the account once one party has lost capacity.
The financial consequences can be significant: direct debits may bounce, mortgage arrears can accumulate, and investment opportunities may be missed. In the worst cases, the inability to access funds can directly affect the quality of care you receive. When you consider that residential care in England currently costs around £1,100-£1,300 per week — and nursing care can reach £1,400-£1,500 per week or more — the inability to access funds to pay for appropriate care is a genuinely serious problem. As Age UK highlights, not having an LPA can lead to significant financial complications, emphasising the importance of planning ahead.
Effect on Healthcare Decisions
In the absence of an LPA for health and welfare, healthcare decisions become significantly more complicated. Without a legally appointed attorney, medical professionals will make treatment decisions in what they consider to be your best interests — but these may not align with what you would have chosen for yourself.
For routine day-to-day medical decisions, doctors and care staff will consult with family members where possible, but the family has no legal authority to override clinical decisions. For more serious decisions — such as whether to move you into a care home, or whether to proceed with a significant medical procedure — the matter may need to be referred to the Court of Protection, causing delays in your care.
An advance decision to refuse treatment (ADRT) can cover specific treatments you wish to refuse, but it cannot cover the full range of ongoing healthcare decisions that arise during a period of incapacity. Only a Health and Welfare LPA provides a trusted person with the comprehensive legal authority to make these decisions on your behalf.
By understanding the consequences of losing mental capacity without a Lasting Power of Attorney, you can take proactive steps now to protect your interests and ensure that your loved ones are legally empowered to act quickly when it matters most.
Who Makes Decisions on Your Behalf?
If you become incapacitated without having set up a Lasting Power of Attorney, the legal position can become uncertain — and often distressing for families who discover they have no automatic right to manage their loved one’s affairs.
Role of Family and Friends
Family and friends often play a central role in caring for someone who has lost mental capacity. However, without a valid LPA, they have no legal authority to make financial or major healthcare decisions on that person’s behalf. They cannot access sole-name bank accounts, sell property, manage investments, or make binding decisions about care placements.
It’s one of the most common and damaging misconceptions in English law: people assume that being a spouse, civil partner, or adult child automatically grants the legal right to manage someone’s affairs. It does not. A husband cannot access his wife’s sole bank account simply because they are married. An adult daughter cannot sell her father’s house to fund his care without legal authority.
Without an LPA, the only route is to apply to the Court of Protection to be appointed as a deputy — a process that costs more, takes months, and subjects the deputy to ongoing court supervision and annual fees for the entire duration of the deputyship.
Involvement of the Court of Protection
The Court of Protection is a specialist court established under the Mental Capacity Act 2005 that makes decisions on behalf of individuals who lack mental capacity. If someone becomes incapacitated without an LPA, the Court is the only body that can grant legal authority to another person to manage their affairs.
The Court can appoint a deputy — this could be a family member, friend, or in some cases a professional deputy (such as a solicitor or local authority representative) — depending on the circumstances and the individual’s best interests. Family members do not have an automatic right to be appointed; if there are disputes between family members, the Court will decide who is most suitable, or may appoint a professional deputy instead. For more information on planning to protect your family, you can visit our page on securing your family’s assets.
The deputyship process involves court application fees, potential solicitor costs for preparing the application, a security bond (insurance policy), and ongoing annual supervision fees payable to the Office of the Public Guardian. All of this can be avoided entirely by setting up LPAs while you still have capacity. The contrast is stark: a straightforward LPA can be set up relatively quickly and affordably, while a deputyship application costs significantly more and takes months — with ongoing costs every year thereafter.
The Court of Protection: An Overview
In England and Wales, the Court of Protection is responsible for handling the affairs of individuals who are no longer able to make decisions for themselves. This court plays a vital role in ensuring that the rights and welfare of vulnerable people are protected when no prior planning has been put in place.
What Is the Court of Protection?
The Court of Protection is a specialist court established under the Mental Capacity Act 2005 that makes decisions on behalf of individuals who lack mental capacity. It has the authority to appoint deputies to manage the financial and welfare affairs of these individuals, make one-off decisions about specific issues, and resolve disputes between family members about what is in someone’s best interests.

How Decisions Are Made
Decisions made by the Court of Protection are guided by the best interests principle set out in the Mental Capacity Act 2005. The court’s primary concern is to ensure that any decision made on behalf of a person lacking mental capacity reflects what is genuinely best for them.
In determining best interests, the Court considers a range of factors: the individual’s past and present wishes and feelings (including any written statements made when they had capacity), their beliefs and values, and the views of anyone engaged in caring for them or interested in their welfare. The Court will also consider whether the person is likely to regain capacity and whether the decision could be postponed until they do.
| Decision-Making Factor | Description | Considerations |
|---|---|---|
| Mental Capacity Assessment | Evaluating the individual’s ability to make the specific decision in question | Medical professionals’ assessments, the two-stage test under the Mental Capacity Act, decision-specific and time-specific evaluation |
| Past and Present Wishes | Considering the individual’s previously expressed wishes and current feelings | Written statements, advance decisions to refuse treatment (ADRTs), conversations with family and carers |
| Best Interests | Ensuring decisions are made for the individual’s overall benefit | Family and friends’ input, professional medical and care advice, the least restrictive option principle, the individual’s beliefs and values |
By understanding how the Court of Protection works and its role in managing the affairs of individuals who lack mental capacity, families can better appreciate why planning ahead with a Lasting Power of Attorney is so important. The Court exists as a safety net — but it is a slow, expensive, and impersonal one compared with having your own chosen attorneys ready to act immediately.
Setting Up a Lasting Power of Attorney
Planning for the unexpected by creating a Lasting Power of Attorney can provide genuine peace of mind for you and your loved ones. It allows you to stay in control of your future by deciding now — while you have full capacity — who can make decisions on your behalf and under what circumstances.
Steps to Create a Lasting Power of Attorney
To set up a Lasting Power of Attorney, you need to follow these steps:
- Choose your attorney(s): You can appoint one or more people to act as your attorney. Consider appointing replacement attorneys as well, in case your first-choice attorneys are unable or unwilling to act when the time comes.
- Decide on the type of LPA: You can create an LPA for Property and Financial Affairs, an LPA for Health and Welfare, or both. We recommend both — they cover entirely different areas of your life.
- Complete the LPA forms: The forms can be completed online through the Office of the Public Guardian’s website or on paper. You’ll need to include details of your attorneys, any specific instructions or preferences, and details of a “certificate provider” — an independent person who confirms you understand the LPA and are not being pressured into making it.
- Have the LPA signed and witnessed: The document must be signed by you (the “donor”), your attorneys, and your certificate provider, in the correct order. Witnesses are also required.
- Register the LPA: The completed forms must be registered with the Office of the Public Guardian. An LPA can only be used once it has been registered, so we recommend registering it straight away rather than waiting — registration currently takes several weeks.
Key Considerations Before Setting One Up
Before setting up a Lasting Power of Attorney, there are several key considerations to keep in mind:
- Mental Capacity: You must have the mental capacity to understand the implications of creating an LPA at the time you make it. If there is any doubt about your capacity, a medical assessment may be advisable — and your certificate provider must confirm they are satisfied you have capacity.
- Choosing the Right Attorney: This is perhaps the most important decision. Your attorney must be someone you trust completely, who understands your values and wishes, and who is capable of managing the responsibilities involved. Consider whether to appoint attorneys jointly (they must all agree on every decision), jointly and severally (they can act together or independently), or a combination of both for different types of decision.
- Including Instructions and Preferences: You can include specific instructions (which your attorneys must follow) and preferences (which they should consider but are not strictly bound by). For example, you might include preferences about where you wish to live if you need care, or instructions about specific financial matters.
- Seeking Professional Advice: While it is possible to set up an LPA yourself, consulting with a specialist in estate planning ensures the LPA is properly drafted and works alongside your other planning documents — such as your will and any lifetime trusts you have in place. As Mike Pugh says, “The law — like medicine — is broad. You wouldn’t want your GP doing surgery.”
By carefully considering these factors and following the necessary steps, you can create a Lasting Power of Attorney that provides genuine security and peace of mind for you and your loved ones — and avoids the far greater cost and stress of the deputyship process.
The Role of Health and Welfare Attorneys
A health and welfare attorney plays a pivotal role in managing your medical care and daily welfare when you’re unable to make decisions yourself. This role is crucial in ensuring that your wishes regarding medical treatment, living arrangements, and day-to-day care are respected and carried out by someone you chose — not a stranger appointed by the court.
Managing Health Decisions
When you lose mental capacity, your health and welfare attorney steps in to make important decisions about your care. This can include decisions about medical treatment, where you live, your daily routine and diet, who you have contact with, and — if you have specifically authorised it in your LPA — decisions about life-sustaining treatment.
Your attorney’s legal duty is to act in your best interests, taking into account your previously expressed wishes, values, and beliefs. For example, if you have always expressed a wish to remain at home rather than go into residential care, your attorney should explore every option to honour that wish before agreeing to a care home placement.
Without a Health and Welfare LPA, these decisions fall to medical professionals and, for major decisions, potentially the Court of Protection — people and institutions that may not know your personal wishes and values at all.
Legal Rights of Health Attorneys
Health and welfare attorneys have specific legal powers defined by the Mental Capacity Act 2005. These powers only become exercisable once the donor (the person who made the LPA) has lost capacity to make the specific decision in question. Unlike a Property and Financial Affairs LPA, a Health and Welfare LPA cannot be used while the donor still has capacity for that decision.
The attorney’s powers can cover:
- Giving or refusing consent to medical treatment
- Decisions about where the person lives
- Day-to-day care decisions, including diet, dress, and daily routine
- Decisions about life-sustaining treatment (only if specifically authorised in the LPA)
To illustrate the importance of having a health and welfare attorney, consider the following comparison:
| Decision Type | With Health and Welfare LPA | Without Health and Welfare LPA |
|---|---|---|
| Medical Treatment | Your chosen attorney decides based on your known wishes and values | Medical professionals decide, or the matter is referred to the Court of Protection — family may be consulted but has no legal authority |
| Life-Sustaining Treatment | Attorney makes decisions based on your specifically authorised preferences | Medical team decides, potentially with Court of Protection involvement, which causes delay and distress for family |
Having a health and welfare attorney ensures that your medical and personal welfare wishes are respected by someone who knows you and cares about you, providing genuine protection and reassurance for both you and your loved ones.
Future Planning for Mental Capacity Loss
Losing mental capacity can be a daunting prospect, but with early planning, you can ensure your wishes are known and legally enforceable. Planning ahead gives you control over your financial, healthcare, and personal welfare decisions — even if you become unable to make them yourself in the future.
The Mental Capacity Act 2005 provides the framework to empower individuals to plan for this possibility, and a Lasting Power of Attorney is the single most important document you can put in place. Unlike a will (which only takes effect on death), an LPA protects you during your lifetime — when you are most vulnerable.
Importance of Early Planning
Early planning is vital for one simple reason: you can only make a Lasting Power of Attorney while you still have mental capacity. Once capacity is lost, it is too late. There is no backdating, no workaround, and no exception. Your family’s only option at that point is the deputyship route through the Court of Protection.
Consider these facts: dementia currently affects around 900,000 people in the UK, with numbers projected to rise significantly over the coming decades. Strokes, accidents, and other sudden events can cause capacity loss at any age — this is not just a concern for the elderly. Yet the majority of adults in England and Wales have not made an LPA.
Having LPAs in place — alongside a properly drafted will and, where appropriate, a lifetime trust to protect your assets — creates a comprehensive safety net. Your LPA ensures someone you trust can manage your affairs immediately if needed, without the delays, costs, and uncertainties of court involvement. A lifetime trust, such as a Family Home Protection Trust, can provide additional protection for your property against care fees, which currently run to £1,100-£1,500 per week or more. Between 40,000 and 70,000 homes are sold to fund care in England every year — proper planning can help avoid your family home becoming one of them.
Tips for Discussing Your Wishes
Discussing your wishes with loved ones and healthcare providers is a crucial step in future planning. It can feel like a difficult conversation to start, but it is one of the most important things you can do for your family. Here are some practical tips:
- Start the conversation early: Don’t wait for a health scare or crisis. The best time to plan is when you’re healthy and clear-headed.
- Be specific about your wishes: Cover both financial management (who should manage your money, how you want bills paid, what to do with property) and healthcare (your views on medical treatment, where you’d want to live, your feelings about life-sustaining treatment).
- Choose your attorneys carefully: Discuss the responsibility with the people you want to appoint. Make sure they understand your wishes and are willing to take on the role.
- Put it in writing: An LPA is a legal document, but you can also write a letter of wishes to give your attorneys additional guidance on your preferences and values — things that may not fit neatly into the LPA form itself.
- Review regularly: Life changes — marriages, divorces, bereavements, and changes in relationships all affect who you might want as your attorney. Review your LPAs periodically and update them if your circumstances change. With the UK divorce rate sitting at around 42%, it’s worth considering what would happen if your chosen attorney’s circumstances change, too.
As Mike Pugh always says: “Plan, don’t panic.” The time you invest in setting up LPAs now could save your family months of stress, thousands of pounds in legal costs, and — most importantly — ensure that you are cared for according to your own wishes, by people you chose yourself.
Legal Advice and Support Options
Understanding the consequences of losing mental capacity without a Lasting Power of Attorney is crucial for making informed decisions about your future. If you’re concerned about your or a loved one’s mental capacity, seeking specialist professional guidance is a vital step.
At MP Estate Planning, our team specialises in helping families across England and Wales put the right protections in place — including Lasting Powers of Attorney, properly drafted wills, and lifetime trusts to safeguard assets. We can help you understand exactly what happens if you lose mental capacity without an LPA and guide you through the process of setting one up quickly and affordably. Not losing the family money provides the greatest peace of mind above all else.
Professional Guidance and Resources
Families and caregivers can benefit from various resources when navigating mental capacity issues. The Office of the Public Guardian provides guidance on LPAs and deputyship applications. The Court of Protection handles applications where someone has already lost capacity. Organisations such as Age UK, the Alzheimer’s Society, and Citizens Advice also offer practical information and support. For comprehensive estate planning that coordinates your LPA with your will and any lifetime trust arrangements, a specialist firm like MP Estate Planning can ensure everything works together seamlessly — because England invented trust law 800 years ago, and these protections exist precisely for families like yours.
Support for Families and Caregivers
Additional support is available through local authorities, NHS services, and charities that provide information, counselling, and advocacy services for families dealing with mental capacity issues. Carers UK and local carers’ organisations can offer practical support and connect families with relevant services. If you are already in a situation where a loved one has lost capacity and no LPA is in place, seeking urgent legal advice about a deputyship application is essential — the sooner you begin the process, the sooner you can gain the legal authority to manage their affairs and ensure they receive proper care.
