The Mental Capacity Act provides a framework to empower and protect people who may lack capacity to make some decisions for themselves. The Mental Capacity Act make clear who can take decisions in which situations, and how they should go about this. Anyone who works with or cares for an adult who lacks capacity must comply with the MCA when making decisions or acting for that person. This applies whether decisions are life changing events or more every day matters and is relevant to adults of any age, regardless of when they lost capacity. The underlying philosophy of the MCA is to ensure that those who lack capacity are empowered to make as many decisions for themselves as possible and that any decision made, or action taken, on their behalf is made in their best interests.
