An umbrella policy only pays once your basic liability limits have been exhausted or the claim is excluded from the basic liability coverage. The claim will be made against you, the policyholder, on behalf of the wronged party. Then your insurance company may pay the settlement amount up to the limits of your coverage.
Excess Liability insurance is a type of policy that provides limits that exceed the underlying liability policy. It is no broader concerning the incidents covered by the primary insurance, meaning it will not expand the stated coverage but will provide higher limits on top of the original policy.
