Under the Mental Health Act 1983, an individual can be appointed to help someone with a 'mental disorder' live as independently as possible in the community. This is called a guardianship order, and the appointed person is the guardian.
The guardian can make some decisions on behalf the person with a mental disorder. These decisions must be the least restrictive and made in the person's best interests.
