The Care Act 2014 protects the rights of all people to be able to make important decisions for themselves as much as possible. However some people can not make decisions about their money, care or other personal matters. The Mental Capacity Act 2005 deals with what happens when someone is considered to not have the capacity to do this for themselves. This might be because they have a learning disability, a mental illness or dementia.
In such a situation it is necessary for someone else to manage their affairs for them. It can help to give peace of mind if these responsibilities can be taken over by someone whom they know.
You can make an advance decision, which means you decide now certain things that will happen if you lose mental capacity later, for instance because you develop dementia. You can choose who will take any decisions if this happens by establishing a Power of Attorney.
