Effective - 28 Aug 2013   104.140. Death prior to retirement, benefits. — 1. (1) If a member who has five or more years of creditable service dies before retirement, the member's surviving spouse, to whom the member was married on the date of the member's death, if any, shall receive the reduced survivorship benefits provided in option 1 of subsection 3 of section 104.090 calculated as if the member were of normal retirement age and had retired as of the date of the member's death and had elected option 1.  (2) If there is no eligible surviving spouse, or when a spouse's annuity has ceased to be payable, the member's eligible surviving children under twenty-one years of age shall receive monthly, in equal shares, an amount equal to eighty percent of the member's accrued annuity calculated as if the member were of normal retirement age and retired as of the date of death. Benefits otherwise payable to a child under eighteen years of age shall be payable to the surviving parent as natural guardian of such child if such parent has custody or assumes custody of such minor child, or to the legal conservator of such child, until such child attains age eighteen, and thereafter, the benefit may be paid to the child until age twenty-one; provided, the age twenty-one maximum shall be extended for any child who has been found totally incapacitated by a court of competent jurisdiction.  (3) No benefit is payable pursuant to this section if no eligible surviving spouse or children under twenty-one years of age survive the member. Benefits cease pursuant to this section when there is no eligible surviving beneficiary through either death of the eligible surviving spouse or through either death or the attainment of twenty-one years of age by the eligible surviving children. If the member's surviving children are receiving equal shares of the benefit described in subdivision (2) of this subsection, and one or more of such children become ineligible by reason of death or the attainment of twenty-one years of age, the benefit shall be reallocated so that the remaining eligible children receive equal shares of the total benefit as described in subdivision (2) of this subsection.  2. Effective January 1, 1985, if an employee who has three or more, but less than five years of creditable service dies before retirement, the surviving spouse of the deceased employee, if married to the deceased employee on the date of the employee's death, or the deceased employee's surviving eligible children under the age of twenty-one, shall receive a total monthly payment equal to twenty-five percent of the deceased employee's accrued monthly benefit calculated as if the employee were of normal retirement age as of the date of death. If the surviving spouse dies leaving any eligible children under the age of twenty-one years, the payment shall continue until the children reach twenty-one years of age. If there is no surviving spouse eligible for benefits under this subsection, but there are any children of the deceased employee eligible for payments, the payments shall continue until the children reach twenty-one years of age. Any benefits payable to eligible children under twenty-one years of age shall be made on a pro rata basis among the surviving children under twenty-one years of age.  3. For the purpose of computing the amount of a benefit payable pursuant to this section, if the board finds that the death was a natural and proximate result of a personal injury or disease arising out of and in the course of the member's actual performance of duty as an employee, then the minimum benefit to such member's surviving spouse or, if no surviving spouse benefits are payable, the minimum benefit that shall be divided among and paid to such member's surviving eligible children under the age of twenty-one shall be fifty percent of the member's final average compensation. The service requirements of subsections 1 and 2 of this section shall not apply to any benefit payable pursuant to this subsection. ­­-------- (L. 1955 p. 718 § 23, A.L. 1969 p. 174, A.L. 1972 S.B. 650, A.L. 1976 H.B. 1211, A.L. 1982 H.B. 1720, et al., A.L. 1984 H.B. 1370, A.L. 1985 H.B. 790, A.L. 1988 H.B. 1643 & 1399, A.L. 2000 H.B. 1808, A.L. 2002 H.B. 1455, A.L. 2013 H.B. 233)  (2013) Section does not discriminate on basis of sexual orientation in violation of equal protection but draws a distinction based on marital status.
