What does the Mental Capacity Act do?
The main principles of the Mental Capacity Act include:
- assume a person has capacity unless proved otherwise
- ensure practical steps have been taken before someone is treated as lacking capacity
- if someone finds some decisions difficult they may be able to make decisions on other things
- if someone does something unwise, strange or eccentric this does not mean they lack capacity
- if you make a decision for someone else, you should involve them as much as possible
- if you make a decision for someone else, it must be in their best interests.
