California’s legislature has passed supported decision-making legislation. We have not located any case law specifically recognizing supported decision-making, but it may still be required as a less restrictive alternative to guardianship.

Cal. Prob. Code §§ 1400 to 1490; 1800 to 1970; 2100 to 2893; 2900 to 2955; Cal. Health & Safety Code § 416 to 416.23 (conservatorship and guardianship for individuals with developmental disabilities)
