For instance, if you have a life insurance policy you can add to this policy a rider to provide term life insurance coverage to cover your spouse and children.
Putting this all on one life insurance policy saves some money by having only one policy fee instead of several individual life insurance policies with separate fees for each one.
The term riders would have a designated beneficiary just like the primary life insurance policy on the other spouse. Usually they would be each other but they don't have to be.
