Does Commercial Umbrella Cover Professional Liability?
Do not assume it does. Professional liability is often treated separately and may be excluded unless the umbrella wording specifically includes it.
Professional liability covers claims arising from professional services and can have different triggers, definitions, and exclusions from general liability. California’s insurance department describes professional liability as its own line, including E&O and malpractice policies. Triple-I notes that professional liability may be excluded from umbrella policies, so a general umbrella limit should not be counted as E&O limit without checking.
Even if a proposal uses broad language about “excess liability,” the policy schedule may only list general liability, auto, or employers’ liability. A separate excess professional liability policy may be available but can follow different terms from a commercial umbrella.
Read the exclusions and underlying schedule for professional services, errors and omissions, technology services, and any separate E&O policy. Ask whether the umbrella follows the professional policy, whether defense costs reduce limits, and what claims-made dates or reporting conditions apply.
