The key differences between a commercial general liability and a professional liability insurance policy concern covered damages, coverage trigger, and covered activities. Commercial general liability policies cover losses caused by a wide array of events, but only if the loss results in bodily injury, property damage, personal injury, or advertising injury and arising from an occurrence as defined in the policy.
Important Note: Some insurers define this term to include only those services listed in the policy application. The named insured may be further required to warrant that this list is an accurate representation of his exposure. Other insurers specifically list those services that the policy intends to cover. Some insurers provide a broad blanket of coverage for “all of the professional services performed by the named insured.”
