A: A personal umbrella liability policy is designed to increase your liability protection. This single policy acts as an “umbrella” over all of your other personal liability policies (home, auto, boat, RV, etc.) so that you have a higher personal liability limit than what would otherwise be available. In certain circumstances, an umbrella policy may provide personal liability coverage that is otherwise excluded from your other policies. For example, an umbrella policy provides coverage anywhere in the world, whereas your auto policy usually provides coverage in the U.S. and Canada only.
