Effective - 28 Aug 2013, 2 histories   104.420. Death before retirement, member or disabled member — surviving spouse to receive benefits — if no qualifying surviving spouse, children's benefits. — 1. Unless otherwise provided by law, if a member or disabled member who has a vested right to a normal annuity dies prior to retirement, regardless of the age of the member at the time of death, the member's or disabled member's surviving spouse, to whom the member or disabled member was married on the date of the member's death, if any, shall receive the reduced survivorship benefits provided in option 1 of section 104.395 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 annuity has ceased to be payable, the member's or disabled 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 or disabled member's accrued annuity calculated as if the member or disabled member were of a 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; 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 or disabled 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 or disabled member's surviving children are receiving equal shares of the benefit described in subsection 2 of this section, 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 subsection 2 of this section.  4. For the purpose of computing the amount of an annuity payable pursuant to this section, if the board finds that the death was the 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 annuity to such member's surviving spouse or, if no surviving spouse benefits are payable, the minimum annuity that shall be divided among and paid to such member's surviving children shall be fifty percent of the member's final average compensation; except that for members of the general assembly and statewide elected officials with twelve or more years of service, the monthly rate of compensation in effect on the date of death shall be used in lieu of final average compensation. The vesting service requirement of subsection 1 of this section shall not apply to any annuity payable pursuant to this subsection. ­­-------- (L. 1984 H.B. 1370, A.L. 1988 H.B. 1643 & 1399, A.L. 1989 H.B. 674, A.L. 1992 S.B. 499, et al., A.L. 1994 H.B. 1149, A.L. 1997 H.B. 356, A.L. 1999 S.B. 308 & 314, A.L. 2000 H.B. 1808, A.L. 2001 S.B. 371, A.L. 2013 H.B. 233)
