The carrier's duty to defend arises whenever the allegations in the complaint state a cause of action that gives rise to the reasonable possibility of recovery under the policy. If any of the claims against an insured arguably arise from a covered event, the insurer is required to defend the entire action. There is a duty defend if the allegations of the complaint are even potentially within the language of the insurance policy.
