Cal. Education Code § 25024

(a) Upon the termination of all employment to perform creditable service subject to coverage under the plan for a reason other than retirement, disability, or death, a member shall be eligible for a termination benefit under the Defined Benefit Supplement Program. (b) A member shall submit an application for a termination benefit on a form prescribed by the system. If a member submits an application for a refund of contributions under the Defined Benefit Program, pursuant to Section 23103, that application shall also be deemed an application for a termination benefit. If a member cancels the application for a refund of contributions under the Defined Benefit Program, the application for the termination benefit shall also be deemed to have been canceled. (c) The member’s employer or employers shall certify in a format prescribed by the system that the member’s employment has been terminated, unless the member’s termination of employment occurred 12 consecutive months or more prior to the date the application for a termination benefit is received by the system’s headquarters office. (d) The termination benefit shall be a lump-sum payment that is equal to the balance of credits in the member’s Defined Benefit Supplement account. (e) Upon distribution of the termination benefit, no further benefit shall be payable to the member or the member’s beneficiary under the Defined Benefit Supplement Program. (f) A partial distribution of the balance of credits in a member’s Defined Benefit Supplement account shall not be made, except as provided in Section 25009, 25015, 25016, or 25022.
