What Happens If You Lose Mental Capacity Without a Power of Attorney

First

What Does ‘Losing Mental Capacity’ Actually Mean?

Mental capacity, in a legal sense, refers to a person’s ability to make and communicate their own decisions. Under the Mental Capacity Act 2005, a person lacks capacity if they are unable to:

• Understand information relevant to a decision
• Retain that information long enough to make a decision
• Weigh up the information to arrive at a decision
• Communicate their decision

Capacity can be lost suddenly — through a stroke, accident, or medical emergency — or gradually, through conditions such as dementia or Alzheimer’s disease. It can also be temporary, as in the case of a serious illness or period of unconsciousness.

Importantly, capacity is decision-specific. A person may have capacity to make some decisions but not others. However, when capacity is lost in a significant or global way, the legal and practical consequences for their family can be profound.

Finances

What Happens to Someone’s Finances?

Bank Accounts Can Be Frozen and Bills Left Unpaid

When a person loses mental capacity and has no Property and Financial Affairs LPA in place, their financial affairs can become effectively frozen. Banks and financial institutions are legally required to protect their customers’ assets and will not allow third parties — including family members — to access accounts without proper legal authority.

This means that even joint account holders may face restrictions on what they can do. A spouse may be able to access a joint current account for day-to-day expenses, but sole accounts, savings, investments and pensions will typically be inaccessible.

The practical consequences can be severe:

• Mortgage or rent payments falling into arrears
• Utility bills and council tax going unpaid
• Pension payments or benefits not being properly managed
• Property being impossible to sell or manage
• Investments going unmanaged at a potentially critical time

All of this falls on the family — who are already dealing with the emotional shock of their loved one’s condition — and yet they may find their hands are completely tied.

Healthcare

What Happens to Healthcare and Care Decisions?

Without a Health and Welfare LPA, Your Family May Have No Legal Say

The consequences extend beyond finances. Without a Health and Welfare LPA, medical professionals are not legally required to consult family members when making treatment decisions for someone who has lost capacity.

Doctors and care teams will always act in what they believe to be the patient’s best interests — but without a Health and Welfare LPA, they have no formal obligation to follow the wishes of a spouse, child or sibling. Decisions about medical treatment, care home placements, and even end-of-life care can be made without meaningful input from the family.

For many families, this is the most distressing aspect of all. Not knowing whether a loved one’s personal wishes and values are being considered — or being excluded from conversations about their care — can cause lasting emotional harm.

A Health and Welfare LPA changes this entirely. It gives the appointed attorney the legal authority to be involved in all care and treatment decisions, and if the donor has chosen to include it, the right to consent to or refuse life-sustaining treatment on their behalf.

Legal

The Only Legal Alternative: Applying to the Court of Protection

A Process That Is Lengthy, Costly and Stressful — but Often the Only Option

If someone loses mental capacity without an LPA in place, their family’s only legal recourse is to apply to the Court of Protection to be appointed as their deputy. This is a formal court process that carries significant burdens.

The process typically involves:

• Completing detailed application forms and medical evidence
• Paying court fees — currently £371 for a property and affairs deputyship application
• Waiting many months for the application to be processed
• Obtaining a security bond (an insurance policy required by the court)
• Submitting annual accounts and reports to the Office of the Public Guardian

Total costs — including legal fees, court fees, the security bond and annual supervision fees — can run to several thousand pounds. And throughout the application process, which can take six months or more, the person’s financial affairs remain in limbo.

Even once a deputy is appointed, they operate under ongoing court supervision — a level of scrutiny that an LPA attorney does not face. The freedom and flexibility that comes with an LPA simply cannot be replicated through the deputyship process.

Urgent

What About Urgent Situations — Is There Any Emergency Option?

In urgent cases — where a decision needs to be made quickly and there is no time to wait for a full Court of Protection application — it is possible to apply for an emergency or interim order. These can be granted more quickly, but they are limited in scope, expensive, and still require court involvement.

Some banks also have their own vulnerable customer processes that may allow limited access to funds in urgent circumstances, but these are discretionary and inconsistent across institutions.

The honest answer is that there is no easy emergency alternative to an LPA. Every option available when capacity has already been lost involves more time, more cost and more stress than simply having an LPA in place from the outset.

Solution

The Solution Is Simple — and It Starts With a Conversation

Setting up a Lasting Power of Attorney is a straightforward process when done at the right time — meaning while the person still has full mental capacity. At Manners Pimblett Solicitors, Edith Longden guides clients through the process clearly and compassionately, ensuring that the document accurately reflects their wishes and is properly registered with the Office of the Public Guardian.

There are two types of LPA, and we typically recommend that clients consider setting up both:

• Property and Financial Affairs LPA — gives your attorney authority to manage your bank accounts, pay bills, manage property and handle financial decisions
• Health and Welfare LPA — gives your attorney authority to make decisions about your medical treatment, care and day-to-day welfare

Once registered, an LPA gives both you and your family enormous peace of mind. You know that if the worst happens, the right person is in place to act on your behalf — guided by your wishes, not left to navigate a complex legal process in a moment of crisis.
