In California, three designations of persons may legally make health-care decisions for the patient: a surrogate, a court-appointed conservator, and a health-care agent named by the patient. Conservators and agents are named through formal proceedings or by a witnessed legal document and their authority lasts until they are replaced or become unavailable. In contrast, surrogates are referred to when there is no agent or conservator, and they may also be named orally by the patient by speaking to his/her supervising physician. The surrogate's authority lasts only as long as the patient stays in a health facility.
