"the insurance was through his employer . . ."
======================================
My response:
Okay, that's what I needed to know. First, insurance beneficiary proceeds do NOT become part of a decedent's estate. Such funds bypass the decedent's estate, and are paid directly to the named beneficiary. This is "contractual" in nature and, by virtue of the contract, the insurance company is merely fulfilling the contract.
Second, his ex wife will be able to take from the policy because he failed to change his beneficiary.
The Employee Retirement Income Security Act of 1974 ("ERISA") was enacted to establish employee benefit plan regulation as a matter of exclusive federal concern. [Pilot Life Ins. Co. v. Dedeaux (1987) 481 U.S. 41, 46, 107 S.Ct. 1549, 1552]
Except for state laws regulating banking, securities or insurance, ERISA "shall supersede any and all State laws insofar as they may now or hereafter relate to any employee benefit plan." [ERISA § 514(a); 29 USCA § 1144(a) (emphasis added)]
State laws "regulating insurance" are expressly exempted from ERISA preemption. [ERISA § 514(b); 29 USCA § 1144(b)(2) (A)]
In the U.S. Supreme Court case of Egelhoff v. Egelhoff (2001) 532 U.S. 141, 146-149, 121 S.Ct. 1322, 1327-1328, the Court stated that the "statute automatically revoking spouse as beneficiary of nonprobate assets upon divorce was preempted by ERISA to extent it applies to ERISA plans (here, employer-provided life insurance policy)".
Thus, where an employee designates his or her spouse as beneficiary of an employer-provided (and hence, ERISA-governed) group life insurance policy, and the parties thereafter divorce without changing beneficiary designations, the now former (nonemployee) spouse is entitled to the policy proceeds when the participant dies despite a state statute automatically revoking designation of a spouse as beneficiary of nonprobate assets upon divorce. [Egelhoff v. Egelhoff, supra, 532 U.S. at 146-150, 121 S.Ct. at 1327-1329]
