661—402.102 (97A) Application of Iowa Code Supplement section 97A.6, subsection 12. Iowa Code Supplement section 97A.6, subsection 12, applies to the deceased member’s spouse and children only if the spouse was married to the deceased member at or before the time of retirement and the children are the natural children of the deceased member or were legally adopted at or before the time of retirement of the member. If there is no surviving spouse of a marriage solemnized prior to retirement of a deceased member, then “surviving spouse” means a surviving spouse of a marriage of two years or more solemnized subsequent to the retirement of the member.
