California Code, Welfare and Institutions Code - WIC § 16123

The provisions of Section 16120, permitting the payment of adoption assistance until a child attains 18 or 21 years of age if the child has mental or physical handicaps, or effective January 1, 2012, up to 21 years of age, if the child or nonminor meets the criteria specified in paragraph (3) of subdivision (d) of Section 16120, shall be effective as long as federal funds are available under Title IV-E of the federal Social Security Act (Part E (commencing with Section 670) of Subchapter 4 of Chapter 7 of Title 42 of the United States Code), and the state continues to exercise its option to extend payments up to 21 years of age, pursuant to Section 473(a)(4) of the federal Social Security Act (42 U.S.C. Sec. 673(a) (4)).  When those funds cease to be available, the maximum length for payment of the Adoption Assistance Program shall be five years except in instances in which there is a continuing need, related to a chronic health condition of the child which necessitated the initial financial assistance.  On and after October 1, 1992, the parent may petition the department or the responsible county to continue financial assistance up to the age of majority.
