Welfare Deputies: What Their Authority Means in Healthcare
Share
A relative tells you, “I’m her deputy, so I make her healthcare decisions.”
As a student nurse, you do not need to know Court of Protection procedure from memory. You do need to recognise that the word deputy does not, by itself, tell you what that person is legally allowed to decide.
In England and Wales, a deputy is appointed by the Court of Protection for somebody who lacks capacity to make particular decisions. There are deputies for property and financial affairs and deputies for personal welfare. If the issue in front of you is healthcare, the first distinction is obvious but easy to miss: a financial deputy does not become a healthcare decision-maker simply because they are the patient’s deputy. Even a personal welfare deputy only has the powers the court has actually given them.
The court order is where the authority comes from
A personal welfare deputy may have authority over areas such as care, accommodation or medical treatment, but the exact scope is set out in the Court of Protection order. Current Office of the Public Guardian guidance is very clear about this: deputies can only make decisions in the areas authorised by their order.
So if somebody says they are the patient’s deputy, healthcare staff need to establish what kind of deputyship it is and what the order covers. This is not about distrusting the relative. It is about making sure that a legally significant decision is being made by the person who actually has authority to make it.
The patient also remains central. Deputyship does not mean that every future decision has been transferred permanently to somebody else. Capacity is decision-specific and time-specific under the Mental Capacity Act 2005. A deputy must consider whether the person can make the particular decision themselves, and the Act requires support to be given to help the person decide wherever practicable. If the patient has capacity for the decision in front of you, it is their decision.
Why you may rarely meet a personal welfare deputy
Most decisions about the care or treatment of an adult who lacks capacity in England and Wales do not require a personal welfare deputy. The Mental Capacity Act provides a framework in which the relevant decision-maker can make a decision in the person’s best interests, provided the requirements of the Act are met.
Personal welfare deputyships are therefore much less common than property and financial affairs deputyships. The Mental Capacity Act Code of Practice describes them as being needed in particularly difficult cases, for example where a series of linked welfare decisions needs to be made over time or where serious family disputes are affecting future care. Current GOV.UK guidance similarly says the court will usually appoint a personal welfare deputy where there is doubt that decisions will otherwise be made in the person’s best interests or where somebody needs authority over a particular issue over time.
There is an important legal reason for that approach. When the Court of Protection is considering a matter, the Act requires it to consider whether it would be better for the court to make the decision itself rather than appointing a deputy to make it. Deputyship is not intended to hand broad control of a person’s life to somebody else simply because the person has impaired capacity in some areas.
A deputy is not the same as an attorney
This is a distinction worth getting comfortable with because the terms can easily blur together on placement.
A Health and Welfare Lasting Power of Attorney (LPA) is created by a person while they have capacity. They choose who they want to act as their attorney if they later lose capacity for relevant health and welfare decisions. The LPA must be registered before it can be used, and a health and welfare attorney can only act when the donor lacks capacity for the decision concerned.
A personal welfare deputy, by contrast, is appointed by the Court of Protection after the need for court-authorised decision-making has arisen. Their authority comes from the court order, not from an appointment previously made by the patient.
The difference becomes particularly important around life-sustaining treatment. A person making a Health and Welfare LPA can specifically choose to give their attorney authority to consent to or refuse life-sustaining treatment on their behalf. A personal welfare deputy does not have that same power. Office of the Public Guardian guidance states that a deputy cannot stop treatment aimed at keeping the person alive. If a serious treatment dispute cannot be resolved, the Court of Protection may need to become involved.
What happens when there is no deputy?
If an adult lacks capacity for a healthcare decision and there is no attorney or deputy with relevant authority, that does not mean treatment decisions are automatically handed to the nearest relative. “Next of kin” is not, by itself, a legal healthcare decision-making role under the Mental Capacity Act.
The relevant decision-maker must follow the Act and determine what is in the person’s best interests. That includes considering the person’s past and present wishes and feelings, beliefs and values, and, where practicable and appropriate, consulting people involved in their care or interested in their welfare. Family knowledge can therefore be extremely important without necessarily giving the family member legal authority to make the decision.
There are circumstances where an Independent Mental Capacity Advocate (IMCA) must be involved. For example, when an NHS body is considering serious medical treatment for a person who lacks capacity for that decision and there is nobody appropriate, other than paid staff, who can be consulted about their best interests, the Mental Capacity Act requires the NHS body to instruct an IMCA, subject to the provisions for urgent treatment. The IMCA represents and supports the person within the decision-making process; they do not simply become the person who gives consent.
What should you do when somebody says they are the deputy?
For a student nurse, the safest response is neither to challenge the relative yourself nor to accept the statement as proof of authority. Tell the registered nurse responsible for the patient and make sure the legal authority is checked through the appropriate local process.
You may see a copy of the Court of Protection order in the records or the team may need to obtain and verify it. What matters clinically is the wording of the order and whether it covers the decision currently being considered. A person might have authority over where the patient lives but not the treatment decision being discussed. Another deputy may have powers concerning finances only.
While that is being established, keep speaking to the patient in a way they can understand and involve them as fully as possible. Do not start addressing every question to the deputy simply because a court order exists. Capacity can vary between decisions, and a person who cannot make one complex decision may still make many others for themselves.
If there is disagreement about treatment, particularly serious or life-sustaining treatment, bring it to senior clinicians rather than trying to interpret the legal documents independently. The Court of Protection can make decisions about health and welfare matters for people who lack capacity, including one-off decisions where that is required.
If you train in Scotland, do not translate the roles directly
Scotland does not use the Mental Capacity Act 2005 or the Court of Protection deputyship system. Adults with incapacity are supported under the Adults with Incapacity (Scotland) Act 2000, which includes powers such as welfare guardianship, intervention orders and welfare powers of attorney.
A Scottish welfare guardian may have powers relating to personal welfare, but those powers come from the guardianship order and must be read in the context of Scottish legislation. Medical treatment for an adult who cannot consent also has its own framework under Part 5 of the Adults with Incapacity Act. For non-emergency treatment, an authorised healthcare professional may need a section 47 certificate of incapacity, and the legislation contains duties concerning consultation with guardians, attorneys and interveners who have relevant powers.
So a welfare guardian is not simply the Scottish name for an England and Wales personal welfare deputy. The practical lesson is much more useful than memorising equivalent labels: find out which legal framework applies, identify the authority the person actually holds and check whether it covers the decision being made.
That is the part you are likely to need on placement. When somebody tells you, “I’m the deputy,” you do not need to become the lawyer in the room. You need to recognise that the statement has legal significance, keep the patient involved, and make sure the team verifies the authority before relying on it.
