A Lasting Power of Attorney is a legal document that allows an individual to appoint one or more people to make decisions on their behalf should they lose the mental capacity to do so in the future. In the context of dementia, this document is a critical component of a proactive care plan. Because dementia is a progressive condition that eventually affects executive function and decision making, having an LPA in place ensures that a person affairs are managed by individuals they trust, rather than a court-appointed deputy.
In a clinical setting, an LPA provides a clear framework for healthcare professionals and financial institutions. It removes the ambiguity that often arises when a patient can no longer express their wishes or consent to treatment. By establishing an LPA early in the diagnosis, families can avoid significant legal hurdles and financial strain, ensuring that the patient’s dignity and preferences remain the priority throughout the progression of the disease.

The two types of Lasting Power of Attorney
There are two distinct types of LPA, and it is common clinical advice for individuals with dementia to set up both to ensure comprehensive protection.
Property and Financial Affairs LPA
This document gives the attorney the authority to make decisions regarding the donor money and assets. This includes managing bank accounts, paying household bills, collecting pensions or benefits, and selling property if the donor needs to move into residential care. Uniquely, this LPA can be used while the donor still has capacity if they choose, which is helpful if physical frailty makes visiting a bank difficult.
Health and Welfare LPA
This LPA can only be used once the donor has lost the mental capacity to make their own decisions. It covers critical life choices such as daily care routines, diet, medical treatments, and where the person should live. Crucially, it also allows the attorney to make decisions about life-sustaining treatment, provided this power was explicitly granted in the original document.
Mental capacity and the certificate provider
A Lasting Power of Attorney must be created while the individual still has the mental capacity to understand the nature and effect of the document.
During the application process, a certificate provider must sign the forms. This is an impartial person: often a GP, solicitor, or a long term friend, who confirms that the donor understands what they are doing and is not being pressured by others. From a clinical perspective, a diagnosis of dementia does not automatically mean a person lacks capacity. Many people in the early stages of the condition are fully capable of appointing an attorney. However, as the disease progresses, it becomes harder to satisfy this legal requirement, which is why early action is essential.
The role of the Office of the Public Guardian
Once the forms are completed and signed, they must be registered with the Office of the Public Guardian before they can be used legally.
The registration process typically takes around 20 weeks. During this time, the Office of the Public Guardian ensures that the document has been created correctly and provides a period for certain people to object if they believe the donor was pressured. Once registered, the document becomes a powerful legal instrument. Clinicians and banks will require a certified copy of the registered LPA before they can discuss confidential details with the appointed attorney.
Comparison of LPA types and powers
| Feature | Property and Financial Affairs | Health and Welfare |
| When it can be used | Immediately (with permission) or after loss of capacity | Only after loss of capacity |
| Decisions covered | Bills, property, bank accounts, investments | Daily care, medical treatment, care home choice |
| Life sustaining treatment | Not applicable | Optional power granted by the donor |
| Attorneys | Can act alone or together | Can act alone or together |
| Supervision | Monitored by the Office of the Public Guardian | Monitored by the Office of the Public Guardian |
Benefits of early legal planning
For a person with dementia, the primary benefit of an LPA is the peace of mind that comes from knowing their future is secure.
Without an LPA, if a person loses capacity, their family must apply to the Court of Protection for a Deputyship. This is a significantly more expensive and time consuming process that requires annual reports and court fees. Furthermore, a deputy may not have the same level of knowledge about the person personal wishes as a chosen attorney. Having an LPA ensures that decisions are made by someone who knows the person values and preferences, fostering a much more person-centred approach to care.
To summarise
Lasting Power of Attorney is a vital legal tool that protects the interests of people living with dementia. By appointing trusted attorneys for both financial and health matters, individuals can ensure their wishes are respected even when they can no longer speak for themselves. The clinical emphasis is on acting early while mental capacity remains, as this allows the donor full participation in the planning process. Ultimately, an LPA reduces stress for family members and provides a clear, legal path for medical and financial management as the condition progresses.
emergency guidance
While legal planning provides long term security, sudden changes in a person’s health are clinical emergencies. Call 999 or seek immediate medical help if a person with dementia experiences a sudden onset of facial drooping, arm weakness on one side, or slurred speech, as these are signs of a stroke. Additionally, be alert for delirium: a sudden and profound state of confusion often triggered by a severe infection like a urinary tract infection. Delirium is a medical emergency that requires urgent hospital assessment to prevent permanent brain damage. A sudden inability to wake up or a significant fall resulting in injury also requires immediate emergency evaluation.
Who can I choose as my attorney?
Most people choose a spouse, an adult child, or a close friend. You can also choose a professional, such as a solicitor or an accountant, although they will charge for their services.
Can I have more than one attorney?
Yes. You can appoint multiple attorneys and decide whether they must make all decisions together (jointly) or if they can make some decisions individually (jointly and severally).
What if I change my mind after I have signed?
As long as you still have mental capacity, you can revoke or end your Lasting Power of Attorney at any time by sending a deed of revocation to the Office of the Public Guardian.
Does an LPA give the attorney the right to my money?
No. Attorneys have a legal duty to act in your best interests and keep your money separate from their own. The Office of the Public Guardian has the power to investigate and remove an attorney if they suspect financial abuse.
What happens if I don’t have an LPA?
Your family may not be able to access your bank accounts to pay for your care or bills, and doctors may have to make medical decisions based on their own clinical judgment rather than your known wishes.
Is an LPA the same as an ordinary Power of Attorney?
No. An ordinary Power of Attorney is usually for a fixed period and becomes invalid if you lose mental capacity. Only a Lasting Power of Attorney remains valid after capacity is lost.
