Excess Liability vs. General Liability: Which Does a Business Need?

General liability responds to covered claims within its own policy terms and limits, including specified bodily injury or property damage claims. Excess liability generally does not replace that primary policy; it may pay only after the underlying insurance is exhausted. California’s regulator describes excess or umbrella policies as additional limits over existing liability insurance.

An excess policy’s scope can vary. Some forms closely follow an underlying CGL policy, while an umbrella may have distinct terms or potential coverage beyond the underlying policy. Neither product automatically covers professional errors, cyber incidents, or D&O claims.

Review the contract requirements and exposures first, then compare primary limits with excess attachment requirements and exclusions. Make sure the excess policy names the correct CGL form and limit and understand whether defense costs erode the underlying or excess limit.
