Welf. & Inst. Code, § 10002

When an applicant for or recipient of public social services is incapable of managing his own resources and planning or carrying out arrangements for his own care and maintenance, and the applicant or recipient cannot secure the services of a private attorney, if authorized by the board of supervisors, the county counsel at the request of the county department, or the district attorney, if a county counsel does not exist, may initiate and carry out proceedings for the appointment of a public or private guardian or public or private conservator, or for changing the form of legal protection when this is indicated. Costs incurred in such proceedings for the protection of applicants or recipients, when not available from the person’s own resources, shall be a proper welfare administrative or service cost, except where a relative engages a private attorney to accomplish this purpose.
