A survivorship (second-to-die) life insurance policy pays the death benefit:

Explanation

A survivorship, or second-to-die, policy covers two lives and pays a single death benefit only after both insureds have died, which is why it is commonly used to provide estate liquidity for heirs. Paying at the first death describes a joint (first-to-die) policy. Paying a living insured at maturity describes an endowment feature. Monthly installments over both lives describes a settlement or annuity arrangement. The delayed, second-death payout is what makes survivorship policies relatively economical for estate planning.
