(b) Sections 6205, 6206, and 6227 apply to every California statutory will, including those executed before January 1, 1985.  Section 6211 applies only to California statutory wills executed after July 1, 1991.

(c) Notwithstanding Section 6222, and except as provided in subdivision (b), a California statutory will is governed by the law that applied prior to January 1, 1992, if the California statutory will is executed on a form that (1) was prepared for use under former Sections 56 to 56.14, inclusive, or former Sections 6200 to 6248, inclusive, of the Probate Code, and (2) satisfied the requirements of law that applied prior to January 1, 1992.
