Irrevocable vs. Contingent Beneficiary
Beneficiary: a person who receives money from a life insurance policy.
Irrevocable Beneficiary: if the current beneficiary has been appointed as irrevocable, the employee may only make changes to their beneficiary appointment with the consent of the current beneficiary.
Contingent Beneficiary: a backup beneficiary; a person who receives the money from the life insurance policy if the first beneficiary dies before the insured.
