There are two basic types of life insurance beneficiaries: Primary beneficiary: The primary beneficiary is the person (or persons) who will receive the proceeds of the life insurance policy when the insured person dies. However, the primary beneficiary will not receive any proceeds if he or she dies before the death of the named insured.
Estate: You may name your estate as the primary beneficiary or as the contingent beneficiary of your death benefit. If you name your estate as your primary beneficiary, do not name a contingent beneficiary.
