There are 5 main principles under the Act:

  • That a person is assumed to have capacity to make a decision until it is proven otherwise.
  • Every effort should be made to encourage and support people to make decisions for themselves.
  • People have the right to make unwise or eccentric decisions.
  • If a person lacks capacity then any decision made must be in that person’s best interests.
  • Decisions made on behalf of a person who lacks capacity must favour the least restrictive option, in terms of the person’s rights and freedoms. This applies, for example, to decisions around where a person who lacks capacity should live.

Having assessed someone’s capacity the practitioner involved may check the quality of their assessment using an audit tool.
