Survivorship life insurance ("second-to-die" or survivor insurance) provides one policy that insures the lives of two people, usually spouses. No proceeds are paid when the first spouse dies. The policy remains in effect and premiums may need to be paid. The death benefit is not paid to the beneficiary until the death of the second insured.
Survivorship life insurance may be a good strategy in cases where one member of a couple is in less than good health, making other types of insurance extremely expensive. Since two lives are insured, premiums for survivorship life policies are relatively low cost compared to individual policies on each spouse's life.
