What is the meaning of mental capacity
Mental capacity is normally defined by a person’s ability to make decisions for themselves, at the time a decision needs to be made. Mental incapacity, where a person is unable to make decisions for themselves, can be due to several reasons and include those with:
- a severe learning disability
- a brain injury
- a mental health illness
- a stroke
- unconsciousness caused by an anaesthetic or sudden accident
However, just because a person has one of these health conditions does not always mean they lack the mental capacity to make a specific decision for themselves. It could be that whilst they lack the capacity to make more complex decisions (for example, regarding financial issues) they still can have the capacity to make other decisions (for example, how to dress and make general day to day decisions)
Mental incapacity, where you lack capacity to make a decision, is normally defined if you are unable to:
- understand information given to you relevant to the decision
- retain the information given to you for long enough to be able to make the required decision
- use or weigh up all your options before making your decision; and/or
- to communicate your decision (whether by talking, using sign language or any other means).
If you lose mental capacity the Mental Capacity Act 2005 (MCA) is there to protect you and your rights.
What is the Mental Capacity Act?
The Mental Capacity Act (MCA) is designed to protect and empower people who may lack the mental capacity to make their own decisions about their care and treatment. It applies to people aged 16 and over.
MCA can cover decisions about day-to-day things like what to wear or what to buy for the weekly shop; or it can also cover more serious life-changing decisions like whether there is a need to move into a care home or decisions regarding major surgery for example.
Anyone who makes decisions on behalf of another individual must follow the five key principles of the Mental Capacity Act. These five principles are:
- Presumption of capacity
- Support to make a decision
- Ability to make unwise decisions
- Best interest
- Least restrictive
The principles under 4 and 5 only apply when a person has been assessed to not have the mental capacity regarding the decision in question. Whilst it is not a principle of the Act, it is key to remember that mental capacity is time and decision specific.
Anyone who has the responsibility to make decisions on behalf of someone else must also follow the Mental Capacity Act Code of Practice and only make decisions that are in their best interests. Furthermore, before someone can make decisions on behalf of an incapacitated individual, they should undertake a comprehensive mental capacity assessment.
Court of Protection and Mental Capacity Law
The Court of Protection is responsible for assisting people that no longer have the mental capacity to make decisions. They are responsible for:
- deciding whether someone has the mental capacity to make a particular decision for themselves
- appointing deputies to make ongoing decisions for people who lack mental capacity
- giving people permission to make one-off decisions on behalf of someone else who lacks mental capacity
- handling urgent or emergency applications where a decision must be made on behalf of someone else without delay
- making decisions about a lasting power of attorney or enduring power of attorney and considering any objections to their registration
- considering applications to make statutory wills or gifts
- making decisions about when someone can be deprived of their liberty under the Mental Capacity Act
Applying to the Court of Protection is quite a complex process that requires specialist legal advice and can take time to arrange. – Find out more about our Court of Protection services
Planning for the future
If you are worried that you or a loved one might lose mental capacity in the future, there are things that you can do in preparation, including considering the following documents:
Lasting Power of Attorney - An LPA means that you give a trusted person or people the power to make decisions for you if you lose the ability to decide for yourself. – find out more about our Lasting Powers of Attorney services or read our blog about
There are two different types of LPA.
Property and financial decisions
Health and welfare decisions
- Make an advance statement – this is not legally binding; however, medical professionals should still make practical effort to follow your wishes. It is a general preference about your treatment and care, and you can make an advance statement if you have mental capacity at the time.
- Make an advance decision - this is legally binding; and It gives you the legal right to refuse specific medical treatment in future when you may not have the mental capacity to make the decision for yourself at that time. An advanced decision cannot be used for anything else.
