Cal. Government Code § 7513

(a) In the case of a state or local retirement system or plan that is subject to Section 401(a)(31) of the Internal Revenue Code, if, under the terms of the system or plan, a person becomes entitled to a distribution that constitutes an “eligible rollover distribution” within the meaning of Section 401(a)(31)(C) of the Internal Revenue Code, the person may elect, under terms and conditions to be established by the administrator of the system or plan, to have the distribution or a portion thereof paid directly to a plan that constitutes an “eligible retirement plan” within the meaning of Section 401(a)(31)(D) of the Internal Revenue Code, as specified by the person. Upon the exercise of the election by a person with respect to a distribution or portion thereof, the distribution by the system or plan of the amount so designated, once distributable under the terms of the system or plan, shall be made in the form of a direct rollover to the eligible retirement plan so specified. (b) The purpose and intent of this section is to enable the state and local retirement systems and plans that are subject to Section 401(a)(31) of the Internal Revenue Code of 1986, as amended, to comply with the requirements of that section regarding the provision of an election for direct rollover of certain plan distributions.
