Life insurance through an employer is common. Most people do not realize the differences between regular life insurance that is purchased from a local agent or through a mail solicitation and life insurance that is purchased through their employer. The major difference is that life insurance purchased through their employer is often governed by the Employee Income Security Act of 1974 (ERISA), which is a life insurance plan governed by federal rules versus state rules otherwise.
Here is a case that is worth reading for anybody dealing with ERISA. It is a 2021, opinion from the 5th Circuit Court of Appeals. It is styled, Erica Talasek v. National Oilwell Varco, L.P.
Ben Talasek had purchased life insurance through his employer. He died and a claim was made by Erica for benefits. The actual facts of the case and the procedural history can be read in the opinion.
