Pension Plans and spouses walk hand in hand. There are many benefits to having a spouse when it comes to retirement benefits. One of these benefits is the fact that a spouse may name the other as a beneficiary to their Pension Plan should they die. This must be in writing and signed by the working spouse. If you would like to name your spouse as the beneficiary to your Pension Plan, then you should make an appointment with your plan representative and put those changes in effect.
