Life insurance has come a long way since the days when it was known as burial insurance and used mainly to pay for funeral expenses. Today, life insurance is a crucial part of many estate plans. You can use it to leave much-needed income to your survivors, provide for your children’s education, pay off your mortgage, and simplify the transfer of assets. Life insurance can also be used to replace wealth lost due to the expenses and taxes that may follow your death, and to make gifts to charity at relatively little cost to you.
