N.J. Stat. § 43:6A-16.2
Whenever a member of the Judicial Retirement System elects a retirement allowance which is payable for the life of the member only and terminating at the member's death, without refund of any kind to the member's 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, other than the survivor benefits provided by section 18 of P.L. 1973, c.140 (C.43:6A-18) and any applicable life insurance benefits. The Division of Pensions and Benefits in the 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 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 the survivor benefits provided by section 18 of P.L. 1973, c.140 (C.43:6A-18) and any applicable life insurance benefits, shall be payable to the beneficiary after the member's death.
