If a Participant in an ERISA qualified Plan retires and elect a survivor annuity for his then wife, that election is locked in by Federal law and cannot be modified a State Court pronouncement to the contrary. Federal law preempts State law. The Plan will continue to pay.
Vanderkam v. Vanderkam, 776 F.3d 883, 892 (D.C. Cir. 2015). The holding in that case confirmed that when a Participant in an ERISA qualified plan retires, his then wife will immediately become irrevocably vested in her entitlement to a QJSA. The only way the Alternate Payee can lose this entitlement is via a waiver previously executed by her within 180 days prior to the commencement date of the Participant's retirement annuity. See 1055 §§(c)(1)(A)(I) and (c)(7)(A). During that 180 day period, the Alternate Payee may also revoke such waiver. See 29 U.S.C. §1055(c)(1)(A)(iii). A waiver executed prior to the applicable election period is void.

In this case the parties were married when the husband retired and was required by ERISA to elect a joint and survivor benefit for his wife. The only way for him to make another election would have been with the consent of his wife. Five years later, after their divorce, Mr. Setzer asked the Plan to permit him to change the survivor annuity election and to name his new wife as the beneficiary. Said the Court:
“In his benefit claim, Setzer requests that in light of his divorce, 1) he be permitted to change the Joint and Survivor annuity (50%) form of pension benefit which he elected at the time he was married to Jessica and prior to his retirement and Annuity Commencement Date; 2) Jessica receive no Surviving Spouse Benefits if she survives him; and 3) he be allowed to name a new spouse beneficiary of his pension benefit should he remarry. (AR 19, 38.) As discussed fully below, ERISA and interpreting Fourth Circuit case law preclude Setzer's request.

“In Hopkins v. AT&T Global Information Solutions Co., 105 F.3d 153 (4th Cir. 1997), the Fourth Circuit directly addressed the question of when a surviving spouse benefit vests in a participant's spouse. The Fourth Circuit concluded that under ERISA, "the Surviving Spouse Benefits vest in the spouse married to the participant on the date of retirement." Id. at 156. The Court went on to conclude that "[u]nless the form of benefit is properly changed prior to retirement, the participant is locked into the joint and survivor annuity upon retirement . . . [and] cannot change the form of benefit, even with the current spouse's consent." Id. at 157. Here, the vesting of the Surviving Spouse Benefits occurred on December 1, 2004, the date of Setzer's retirement and commencement of benefits. Consequently, as a matter of law, Setzer cannot change the Joint and Survivor form of benefit, even though Jessica purported to waive any claim or interest she might have in Setzer's pension benefits.”
