Always name a contingent, or secondary, beneficiary just in case you outlive your first beneficiary.
Select a specific beneficiary rather than having the proceeds of your life insurance paid to your estate. One of the great advantages of life insurance is that it can be paid to your family immediately. If it is payable to your estate, however, it will have to go through probate with the rest of your assets.
Be very specific in wording beneficiary designations. Saying “wife of the insured” could result in an ex-spouse getting the proceeds. Naming specific children may exclude those born later. If your child dies before you, do you want the proceeds to go to that child’s children? Changing the beneficiary designation is easy, but you have to remember to do it.
