Louisiana Revised Statutes Tit. 11, § 473. Surviving spouse and adult children

A. When a married member has major children of both a current marriage and a prior marriage but no minor children of either marriage, the member and nonmember spouse may by written agreement jointly elect to direct the retirement system in writing to divide the benefit established in R.S. 11:471 between the member's current spouse, the children of the present marriage, and the children of the prior marriage, in any agreed proportions, provided the proportionate amounts are clearly set forth in the agreement. Either spouse may revoke the agreement by providing the system with a written revocation prior to the death of the member. The agreement shall be automatically revoked by operation of law in the event that the party spouses become divorced.

B. When a married member has major children of a prior marriage and no minor children of the present marriage, that member may unilaterally elect to direct the retirement system in writing to divide the benefit established in R.S. 11:471 between the member's current spouse and the children of the prior marriage on a pro rata basis, provided there is no pending joint election made pursuant to Subsection A of this Section. The interest of the current spouse shall be based on the ratio of the length of the current marriage to the total state service of the member.

C. The elections set forth in Subsections A and B of this Section may be made even if the member has minor children of the current or prior marriage at the time the election is made, but the election shall not become effective until there are no longer any children of either marriage who are eligible for benefits based on being a minor or a student. The retirement system shall distribute the benefits in accordance with the written election made pursuant to either Subsection A or B of this Section, provided the election is received by the system prior to the member's death.

D. The benefit that is established pursuant to R.S. 11:471 and that is payable pursuant to this Section shall be based on the age and mortality of the surviving spouse and shall cease being paid upon the death of the surviving spouse.
