Insurance proceeds, when payable to a named beneficiary, are not subject to probate, which reduces administration costs.
Life insurance proceeds are received free of federal income tax (under current tax laws).
By providing the estate with the liquidity needed to pay estate settlement costs, life insurance makes it possible to preserve and distribute other estate assets according to the owner's wishes.
Life insurance, typically, is the least expensive way to solve the problem of estate shrinkage, since the dollars needed to meet estate liabilities can be purchased for "pennies on the dollar" each year * and the life insurance proceeds usually exceed the total premiums paid, depending on the insured's age and health.
