Notwithstanding the provisions of P.L. 1954, c. 84 (C. 43:15A-1 et seq.) or any other law to the contrary, whenever a member of the Public Employees' Retirement System elects a retirement benefit which is payable for the life of the member only and terminating at his death, without refund of any kind to the spouse, the member shall be required, before electing that benefit, to sign a form stating that the member has elected that benefit, that the member understands that it is payable during the member's lifetime only and that no benefits will be payable to the member's spouse after death. The Division of Pensions, Department of the Treasury, shall notify the member's spouse if the member identifies the spouse on the form. Notification shall be by certified mail to the spouse's address as provided on the form by the member. If the member has not provided an address for the spouse on the form, the Division of Pensions, Department of the Treasury, shall send the notice, by certified mail, to the spouse at the member's address. The notice shall advise the spouse that the retirement benefit chosen by the member is payable during the member's lifetime only and that no benefits, other than any applicable life insurance benefits, shall be payable to the beneficiary after the member's death.
