Losing Mental Capacity Without a Lasting Power of Attorney

If you lose mental capacity without a Lasting Power of Attorney, no one automatically gains the legal right to manage your affairs. Your family would need to apply to the Court of Protection for a Deputyship Order, a process that can take many months and cost significantly more than setting up an LPA in advance.
It is one of the most common misconceptions in estate planning. Many people across Merthyr Tydfil and South Wales believe that a spouse, adult child or close relative will simply be able to step in and take over if they become unable to manage their own affairs. The truth is quite different. Without a valid Lasting Power of Attorney in place, the law does not allow anyone to act on your behalf, no matter how close they are to you.
At RJM Solicitors, we speak with families every week who are dealing with the consequences of this gap. This article explains what actually happens, what the alternatives involve and why planning ahead makes such a significant difference.

What Is a Lasting Power of Attorney and Why Does It Matter?
A Lasting Power of Attorney (LPA) is a legal document that lets you appoint one or more trusted people to make decisions on your behalf if you lose the mental capacity to do so yourself. There are two types. A Property and Financial Affairs LPA covers things like managing bank accounts, paying bills and dealing with property. A Health and Welfare LPA covers medical decisions and care arrangements.
The key word is lasting. Unlike an ordinary power of attorney, an LPA remains valid even after you lose capacity. That is precisely what makes it so important. For anyone thinking about lasting power of attorney in Merthyr Tydfil or elsewhere in South Wales, the time to act is while you still have full mental capacity. Once capacity is lost, it is too late to make one.
What Happens If You Lose Capacity Without an LPA in Place?
Without an LPA, your family faces a difficult and often distressing situation. They cannot access your bank accounts, manage your property or make decisions about your care without formal legal authority. Even a joint bank account may be frozen in certain circumstances.
The only route available is to apply to the Court of Protection for a Deputyship Order. This gives a person, known as a deputy, the legal authority to act on your behalf. It is a formal court process and it comes with real costs and delays that many families are simply not prepared for.
The 6 Key Stages of the Court of Protection Deputyship Process
Gather medical evidence: A medical professional must confirm that the person has lost mental capacity. This assessment forms the foundation of the application.
Complete the application forms: The applicant must complete several detailed Court of Protection forms, including a declaration about the person's circumstances and finances.
Notify relevant parties: Certain people, including close family members, must be formally notified of the application and given the opportunity to raise any concerns.
Submit to the Court of Protection: The completed application is sent to the Court of Protection in London, along with the required court fee.
Wait for the order: The court reviews the application. This process typically takes between six and twelve months, though timescales can vary depending on complexity and court workload.
Ongoing supervision: Once appointed, a deputy is supervised by the Office of the Public Guardian. Annual reports are required and there are ongoing fees to pay each year.

What Are the Costs and Timescales Involved?
The contrast between setting up an LPA and going through the Deputyship process is significant. Preparing a Lasting Power of Attorney in Merthyr Tydfil with a solicitor typically costs a few hundred pounds in legal fees, plus the Office of the Public Guardian registration fee of £92 per LPA at the time of writing. The process usually takes between eight and twenty weeks from start to finish.
A Deputyship application, by comparison, involves a court application fee of around £432 and ongoing annual supervision fees. Legal costs for preparing and submitting the application can run into thousands of pounds. The process can take six months to over a year. During that time, the family may have very limited ability to manage the person's finances or arrange appropriate care.
These figures are provided as a general guide. Costs and timescales vary depending on individual circumstances and may change over time.
Common Misconceptions About Mental Capacity and Legal Authority
Misconception: My spouse can automatically manage my finances if I lose capacity. This is not the case. Marriage does not grant legal authority over a partner's individual accounts or assets. A joint account may offer some access but it does not cover everything and can still be restricted.
Misconception: I am too young to need an LPA. Mental capacity can be affected at any age, through accident, illness or sudden medical events. An LPA is not just for older people.
Misconception: My family can sort it out between themselves. Without legal authority, family members cannot make binding decisions about your care or finances, regardless of how united they are.
Misconception: A will covers this. A will only takes effect after death. It has no bearing on what happens if you are alive but unable to make decisions for yourself.
What Does This Mean for Businesses and Professionals Across South Wales?
This issue is not limited to individuals and families. Business owners, company directors and sole traders across Cardiff, Newport, Swansea, Bridgend, Pontypridd and Rhondda Cynon Taf face serious risks if they lose capacity without an LPA in place.
Without a Property and Financial Affairs LPA, no one may be able to access business bank accounts, sign contracts or meet payroll obligations. A business can effectively grind to a halt while a Deputyship application works its way through the courts. For HR managers and employers, understanding this risk is also relevant when supporting employees who may be dealing with a family member's incapacity.
Estate agents and conveyancers in South Wales may also encounter situations where a property transaction cannot proceed because a seller or buyer has lost capacity and no LPA exists. This can cause significant delays and financial loss for all parties involved.

Frequently Asked Questions
Can I make a Lasting Power of Attorney for someone who has already lost capacity?
No. An LPA can only be made by a person who currently has mental capacity. If someone has already lost capacity, the only option is to apply to the Court of Protection for a Deputyship Order.
How long does it take to register a Lasting Power of Attorney in Merthyr Tydfil?
Once the LPA is signed and witnessed correctly, registration with the Office of the Public Guardian generally takes between eight and twenty weeks. Timescales can vary and it is generally advisable to start the process well in advance of when it may be needed.
What is the difference between a deputy and an attorney?
An attorney is someone you appoint yourself through an LPA while you have capacity. A deputy is appointed by the Court of Protection after capacity has been lost. Deputies face more ongoing supervision and reporting requirements than attorneys.
Does an LPA cover decisions about medical treatment?
A Health and Welfare LPA can cover decisions about medical treatment and care arrangements, but only once it has been registered and only when the person has lost capacity to make those decisions themselves. A Property and Financial Affairs LPA covers financial matters separately.
Can I have more than one attorney on my LPA?
Yes. Many people appoint more than one attorney and can specify whether they must act together or whether they can act independently. A solicitor can help you think through which arrangement suits your circumstances best.
