Missouri Laws 87.170 – Conditions of retirement
Retirement of a member on a service retirement allowance shall be made by the board of trustees as follows:
(1) Any member may retire upon the member’s written application to the board of trustees setting forth at what time, not less than thirty days nor more than ninety days subsequent to the execution and filing therefor, the member desires to be retired, if the member at the time so specified for such member’s retirement has twenty-five years or more of service; except that a member who ceases to be a firefighter after twenty years or more of service may retire prior to the twenty-five years of service with a retirement allowance based on the member’s years of service;
(2) Any member in service upon attaining the age of sixty, if qualifying for a service retirement allowance equal to seventy-five percent of the average final compensation, shall be retired forthwith; except that with respect to any member, the board shall not retire such member when the member attains sixty years of age or more merely because the member has attained that age unless the member so requests or the member has completed thirty or more years of service, even if a portion of such service is not creditable service pursuant to participation in the deferred retirement option plan prescribed by section 87.182;
(3) Any member who qualifies for a service retirement allowance of seventy-five percent or over and has not attained sixty years of age may be retained as a member until sixty years of age, with no increase in retirement allowance.
