If people depend on your income, life insurance can replace that income for them if you die. The most commonly recognized case of this is parents with young children. However, it can also apply to couples in which the survivor would be financially stricken by the income lost through the death of a partner, and to dependent adults, such as parents, siblings or adult children who continue to rely on you financially. Insurance to replace your income can be especially useful if the government- or employer-sponsored benefits of your surviving spouse or domestic partner will be reduced after your death.
