Perhaps you've loaded up on insurance: high limits on car insurance, home and flood insurance, and ample life insurance. But even these coverages can't account for every disaster in life. To further protect your assets, there's umbrella insurance. Personal umbrella insurance kicks in when the limits of your auto or home insurance have been exhausted and there are still damages to pay. How could that happen? Say, for example, someone falls on your sidewalk and sues you for an ungodly amount. Or say you cause a six-car pile-up on the highway.
