Dementia can be challenging—not just for the person experiencing it, but also for families and carers. Dementia affects memory, thinking, and decision-making, gradually reducing a person’s mental capacity. This loss of capacity can make everyday tasks like managing finances, healthcare, and personal decisions increasingly difficult. But what happens if someone has dementia and no power of attorney in place?

Imagine your father develops dementia, and no one has the legal right to manage his financial or healthcare decisions. Without a Power of Attorney (POA), managing his bank account, organising care, or making urgent medical decisions becomes complicated.

In this article, we’ll address exactly what happens if someone has dementia and no power of attorney in place. We’ll clearly outline the alternatives and solutions available, providing practical and reassuring guidance.

Here’s what you’ll learn in this post:

  • What a Power of Attorney is and its importance for dementia care
  • What happens legally when no Power of Attorney exists
  • Alternatives to Power of Attorney, specifically Deputyship
  • How Deputyship works, including how to apply
  • Who can become a Deputy, and their legal responsibilities
  • How the Mental Capacity Act (2005) relates to dementia cases
  • Whether it’s possible to still obtain a Power of Attorney after a dementia diagnosis
  • Common mistakes families make and how to avoid them
  • Real-life scenarios illustrating why early legal planning matters
  • Why specialist legal advice is essential for dementia care

What is a Power of Attorney and Why is it Important for Dementia?

A Power of Attorney (POA) is a legal document that lets someone else make important decisions on your behalf. This person is known as your attorney. They can help manage your finances, healthcare choices, and other important matters if you ever lose the ability to decide for yourself.

There are two main types relevant to dementia care:

  • Lasting Power of Attorney (LPA) – covers financial affairs, property, health and welfare decisions.
  • Enduring Power of Attorney (EPA) – previously used, covering only financial affairs. Although no longer created, existing EPAs remain valid.

Setting up a POA early, before dementia progresses, is crucial. You must have sufficient mental capacity to legally appoint an attorney. Waiting too long risks losing control over who makes important decisions about your health, care, and finances.

Without a valid POA in place, your family or carers may face significant legal hurdles and delays when trying to manage your affairs. Taking early action helps protect you and your family, providing peace of mind for everyone involved.

What Happens if Someone with Dementia Doesn’t Have Power of Attorney?

If someone develops dementia without a Power of Attorney (POA), family members and carers face complicated legal and practical challenges. Without POA, no one automatically has the right to manage the individual’s finances, property, or healthcare decisions.

Immediate implications include difficulties accessing the person’s bank accounts, paying bills, and managing property. Healthcare and care home decisions become stressful, as medical professionals and care providers can’t simply follow family members’ wishes without legal authority.

To resolve this, families must apply for a Deputyship order from the Court of Protection, adding further complexity and delay.

Deputyship: An Alternative When There’s No Power of Attorney

When someone with dementia no longer has the mental capacity to make their own decisions and has not set up a Power of Attorney (POA), their family must apply for deputyship. This is a legal process that allows a court-appointed person—known as a deputy—to make decisions on their behalf.

Deputyship is granted through the Court of Protection and gives the deputy the authority to manage finances, health, or welfare matters. It is often the only option available once the person with dementia can no longer legally grant POA.

The key difference between POA and deputyship lies in timing and control:

  • A POA is chosen by the individual while they still have mental capacity.
  • A deputy is appointed by the court once capacity is lost.

This means families lose the chance to decide who will take on the role, and the legal process becomes more complex.

Types of Deputyship Orders

There are two types of deputyship orders, depending on the needs of the person with dementia.

Property and Financial Affairs Deputyship

This allows the deputy to:

  • Manage bank accounts
  • Pay bills
  • Collect pensions or benefits
  • Handle property and investments

Example: A son applies to manage his mother’s accounts after she can no longer understand her finances. He uses the deputyship to pay her care home fees and sell her house to fund long-term care.

Personal Welfare Deputyship

This gives the deputy authority to make decisions about:

  • Medical treatment
  • Care arrangements
  • Where the person lives

Example: A daughter applies for welfare deputyship to decide on the best care setting for her father after he can no longer make decisions about his own wellbeing.

This type of deputyship is less common and is usually only granted if there is a dispute about care or no close family available.

How to Apply for Deputyship

Applying for deputyship involves a formal court process through the Court of Protection. Here’s what the process typically involves:

  1. Complete the deputyship application forms – including information about the person’s condition and the applicant.
  2. Obtain a medical assessment of capacity – a qualified professional must confirm that the person lacks capacity.
  3. Submit forms to the Court of Protection – along with the required application fee (usually £371).
  4. Notify relevant people – family members and others involved in the person’s life must be formally informed.
  5. Court review and decision – the court considers the application and may request further details or hold a hearing.

If approved, the deputy will receive a Court Order outlining what they are authorised to do.

Costs include:

  • Court fees
  • Medical assessment fees
  • Annual supervision fees (from £35–£320 depending on complexity)
  • A security bond (for financial deputies)

Timeframes can vary but often take between 8 to 16 weeks, depending on the complexity of the case and whether any objections are raised.

Because of the legal responsibility and strict reporting duties involved, many families seek help from an experienced solicitor to ensure the process is handled correctly.

Who Can Be a Deputy?

Not everyone can act as a deputy. The Court of Protection decides who is most suitable based on the person’s relationship to the individual with dementia and their ability to act in their best interests. Deputies must be over 18 and financially responsible.

People who can be appointed as a deputy include:

  • Family members or close friends
    Often the first choice. They know the person well and understand their needs and preferences.
    Example: A daughter applies to manage her father’s finances and make care decisions as his condition progresses.
  • Professional deputies
    These are solicitors or specialists appointed when no suitable family member is available or where the estate is large or complex.
    Example: A solicitor is appointed when a person with dementia has no close relatives and owns multiple properties.
  • Local authority representatives
    In some cases, a council officer may act as a deputy, especially if the person with dementia is in state-funded care and has no family.
    Example: A local authority steps in when a person with dementia has no known relatives or friends.

Can there be more than one deputy?

Yes. The Court of Protection can appoint multiple deputies, either to act:

  • Jointly – all decisions must be made together, which can be slower but ensures shared responsibility.
  • Jointly and severally – deputies can act together or independently, offering more flexibility.

This is common when siblings or close relatives share the responsibility. The court will decide the most suitable arrangement based on the application and family circumstances.

Things to consider when choosing a deputy:

  • Trustworthiness and reliability
  • Ability to manage money and make sound decisions
  • Understanding of the person’s preferences and values
  • Availability to carry out regular duties

Choosing the right deputy is a serious decision. Deputies are legally accountable and must always act in the best interests of the person they represent.

What Responsibilities Does a Deputy Have?

Once appointed by the Court of Protection, a deputy takes on serious legal responsibilities. They must always act in the best interests of the person with dementia and follow the rules set out by the Mental Capacity Act 2005.

Typical duties fall into two key areas:

Managing Finances and Assets

A property and financial affairs deputy is responsible for:

  • Handling day-to-day money management
  • Paying bills and managing bank accounts
  • Collecting pensions, benefits, or other income
  • Managing savings and investments
  • Arranging the sale or maintenance of property (with permission, if needed)

They must also keep detailed records of all income, spending, and decisions.

Health and Welfare Decisions

A personal welfare deputy (if appointed) may:

  • Decide where the person lives or receives care
  • Make decisions about daily routines and medical treatment
  • Work with doctors and care providers to ensure suitable support

This type of deputyship is less common and usually only granted if there are disputes or no family members available to act.

Annual Deputy Report

All deputies must submit an annual report to the Office of the Public Guardian (OPG). This report includes:

  • A summary of financial decisions made
  • A list of expenses and receipts
  • Any major changes in care or personal circumstances

This ensures accountability and protects the rights of the person with dementia.

Limits on Deputy Decision-Making 

Deputies do not have unlimited powers. Some decisions require prior approval from the Court of Protection or are not allowed at all.

Common limitations include:

  • Selling a property – this usually requires court permission, especially if it’s the person’s main home.
  • Making large gifts – deputies cannot make substantial financial gifts without applying to the court.
  • Changing a will – deputies cannot create or amend a will unless authorised by the court.
  • Making decisions based on personal beliefs – deputies must remain neutral and act in the person’s best interests, not their own.

These restrictions are in place to protect vulnerable individuals and ensure decisions are fair, reasonable, and legally sound. Deputies should always seek professional advice if they are unsure about what they can or cannot do.

How Does the Mental Capacity Act Affect Someone with Dementia

How Does the Mental Capacity Act Affect Someone with Dementia?

The Mental Capacity Act 2005 is the key piece of legislation that protects people in England and Wales who lack the ability to make certain decisions for themselves—often due to conditions like dementia. It outlines how capacity should be assessed and who can legally make decisions on behalf of someone who can’t.

The Act applies to everyone involved in the care or decision-making of someone who may lack capacity, including family members, carers, and professionals. It ensures decisions are made in the person’s best interests, and only when absolutely necessary.

You can read more on the Mental Capacity Act 2005 – NHS Guide for a full overview.

How Is Capacity Assessed?

1. Specific to Each Decision

Capacity is not all or nothing. A person may be able to make some decisions but not others. For example, they might manage daily spending but struggle with selling a house or making a will.

2. Assessed at the Time the Decision Needs to Be Made

Capacity can fluctuate. It must be assessed at the time a decision is required, not based on past or future ability.

3. Based on a Clear Legal Test

To determine capacity, the person must be able to:

  • Understand the relevant information
  • Retain that information long enough to make a decision
  • Weigh up the information to reach a decision
  • Communicate their choice in some form (speech, sign, writing)

If they cannot do any one of these steps, they may be found to lack capacity.

4. Assessment Must Be Carried Out by a Qualified Individual

This is usually a GP, social worker, or other healthcare professional. In legal matters like Deputyship or Power of Attorney, a formal assessment report is required.

Why Timing Matters

Dementia is a progressive condition. A person may appear to cope for a time but lose decision-making ability without warning. Once capacity is lost, it is too late to create a Power of Attorney. This leaves families with fewer options and more legal hurdles.

Acting early ensures the individual’s wishes are respected and allows trusted people to step in legally and responsibly. It also avoids the stress, cost, and delay of applying to the Court of Protection for deputyship.

Can You Still Set Up a Power of Attorney if Someone Already Has Dementia?

Many families ask: can you get power of attorney for someone with dementia? The answer is — it depends on whether the person still has mental capacity.

In the UK, a person can only make a Lasting Power of Attorney (LPA) if they understand:

  • What an LPA is
  • The decisions they are allowing someone else to make
  • The potential consequences of granting this power

If someone has early-stage dementia and still meets this test, it is legally possible to set up a Power of Attorney. However, the process must be handled carefully.

How to Get Power of Attorney for Someone with Dementia in the UK

  1. Check Mental Capacity
    A capacity assessment should be carried out—usually by a GP or solicitor—to confirm the person understands the legal process.
  2. Choose the Type of LPA
    • Property and Financial Affairs LPA
    • Health and Welfare LPA
      You can choose one or both depending on the person’s needs.
  3. Complete the LPA Forms
    These can be downloaded from the GOV.UK website or completed online.
  4. Sign and Witness the Forms
    The donor (person with dementia), attorney(s), witnesses, and a certificate provider (usually a professional) must sign. The certificate provider confirms the donor understands the LPA.
  5. Register the LPA
    Send the signed forms to the Office of the Public Guardian with the registration fee. This step can take up to 20 weeks.

If the person still has the mental capacity to make these decisions, this route avoids the complexity of court applications and puts control in their hands.

What if it’s Too Late for a Power of Attorney? 

If dementia has advanced to the point where the person cannot understand or sign an LPA, it’s no longer legally valid to create one. In this case, families must apply for Deputyship through the Court of Protection.

This means:

  • You lose the ability to choose your attorney
  • The court decides who becomes the legal deputy
  • The process takes longer, costs more, and includes annual reporting duties

It’s crucial to act as early as possible—while the person still has the ability to make informed choices. Early legal planning ensures their wishes are respected and avoids unnecessary delay and stress for loved ones.

Independent Mental Capacity Advocates (IMCA): An Overlooked Resource

An Independent Mental Capacity Advocate (IMCA) is a specially trained professional who supports people who lack mental capacity and have no close family or friends to speak on their behalf. IMCAs are appointed to ensure that the rights and wishes of vulnerable individuals are represented when important decisions are being made.

Under the Mental Capacity Act 2005, an IMCA must be involved in specific situations, particularly when serious decisions need to be made about medical treatment or long-term care arrangements.

How an IMCA Supports People with Dementia

An IMCA helps ensure decisions are made in the best interests of the person with dementia, especially when they cannot express their views. This includes:

  • Making sure the person’s past and present wishes are taken into account
  • Challenging decisions that may not seem in the person’s best interest
  • Gathering information and representing the person during important decisions
  • Acting independently, with no conflict of interest

For example, if an elderly person with dementia needs to move into a care home but has no family, an IMCA would be appointed to review the proposed move and advocate for their preferences.

how an imca supports people with dementia

When and How to Access an IMCA

An IMCA is required when:

  • A person lacks mental capacity to make a decision about serious medical treatment or a long-term move
  • They have no family or close friends to consult
  • The decision is being made by a public body, such as a hospital or local authority

IMCAs are usually arranged by the relevant NHS Trust or local council, who must refer cases that meet the criteria. Individuals cannot apply for an IMCA on behalf of someone else; it must be initiated by the organisation making the decision.

Although not widely known, IMCAs play a vital role in protecting the rights of people with dementia who may otherwise have no one to speak for them. Their support ensures decisions are fair, transparent, and legally compliant.

Common Mistakes to Avoid When Managing Legal Affairs for Someone with Dementia

Caring for someone with dementia is already emotionally and practically demanding. But when legal affairs are handled incorrectly, it can lead to unnecessary delays, added stress, and even financial harm. Here are some of the most common mistakes families make—and how to avoid them.

1. Waiting Too Long to Set Up a Power of Attorney

Mistake: Families often delay creating a Lasting Power of Attorney (LPA), assuming they have more time.
Consequence: If dementia progresses and the person loses capacity, it’s no longer legally possible to make an LPA. You’ll need to apply for Deputyship, which is more complex and expensive.
Avoid it: Set up an LPA as early as possible, ideally at the first sign of memory problems.

2. Misunderstanding Mental Capacity Requirements

Mistake: Assuming someone with dementia automatically lacks capacity, or assuming they still have it without proper assessment.
Consequence: This can lead to invalid legal documents or missed opportunities to create a valid LPA.
Avoid it: Seek a formal capacity assessment if you’re unsure. A solicitor or healthcare professional can help guide the process.

3. Not Getting Legal Advice Before Applying for Deputyship

Mistake: Attempting to apply for Deputyship without understanding the legal steps, costs, or paperwork involved.
Consequence: Incomplete or incorrect applications can cause delays and require resubmission, wasting time and money.
Avoid it: Speak to a solicitor familiar with dementia and the Court of Protection before you start.

4. Assuming Family Members Automatically Have Authority

Mistake: Believing that being a spouse or child gives automatic legal rights to manage finances or make care decisions.
Consequence: Banks, doctors, and care homes cannot act on your instructions without legal authority.
Avoid it: Put the proper legal documents in place—either an LPA or Deputyship—depending on the person’s capacity.

5. Failing to Keep Accurate Records

Mistake: Deputies or attorneys making decisions without keeping a clear record of what they’ve done.
Consequence: You may be challenged by the Office of the Public Guardian (OPG) or family members, and held personally liable.
Avoid it: Keep detailed records of all financial transactions, care decisions, and correspondence. Submit the required annual reports on time.

By avoiding these common errors, you can reduce delays, protect your loved one’s interests, and handle their affairs with confidence and care. DMA Law can provide expert legal guidance to help you get things right from the start.

Why You Need Specialist Legal Support for Dementia Cases

Managing legal affairs for someone with dementia is not straightforward. It often involves strict legal processes, detailed forms, and decisions that can affect someone’s financial security and quality of life. That’s why getting expert legal advice is essential.

Expertise in Court of Protection Procedures

The Court of Protection process for applying for deputyship is time-sensitive and document-heavy. Errors can lead to long delays or rejected applications. A solicitor ensures everything is done correctly the first time, avoiding unnecessary stress for the family.

Accurate Capacity Assessments

Understanding when and how to assess mental capacity is crucial. A specialist solicitor can help arrange formal assessments, explain the legal test for capacity, and guide families through the decision-making process. This can be vital when deciding whether it’s still possible to set up a Lasting Power of Attorney.
