How it works
Universal life is designed to be flexible life insurance. As long as you pay your premiums to keep the insurance part of the policy in force, you can vary the frequency and amount of your premium payments. As a result, you can vary your death benefit. For instance, you can decrease your coverage to coincide with your declining mortgage. If you want more insurance, you might need a medical exam, even if you had one when you originally bought the insurance. It depends on your age and the amount of coverage you're buying.
