# When Should a Business Buy Umbrella Insurance?

Buy or review an umbrella before signing a contract that requires higher limits or when your liability exposures grow.

Buy or review an umbrella before signing a contract that requires higher limits or when your liability exposures grow. It must be coordinated with the underlying policies and their limits. A contract may require higher limits than the primary CGL or auto policy provides, or expansion into new locations, services, vehicles, or markets may change the potential severity of a claim. California’s guide describes umbrella coverage as protection above the limits of basic liability policies.

Timing matters because an umbrella generally has to be coordinated with the policies it sits over. The insurer may require minimum underlying limits and specified forms, and the umbrella may not repair a gap if the underlying policy excludes the claim. A self-insured retention can apply to certain uncovered underlying losses.

Before renewal or contract execution, collect the current declarations and proposed contract limits. Ask the broker to confirm the umbrella’s start date, scheduled underlying policies, attachment requirements, exclusions, retention, and whether endorsements are needed to match the business’s operations.
