It is Always a Good Idea to Read Your Insurance Policy
An insurance broker owes a duty to the client “to use reasonable care, diligence and judgment in procuring the insurance requested by the insured.”1
Looking at the above scenario it would certainly seem that the councilman/broker has liability. It sounds like the company being defrauded never got the insurance at all. However, if the situation were slightly different and the insured had a policy but never took the time to read it to verify terms and coverage, could that be used as an affirmative defense against the insured? Depending on the jurisdiction, the answer is yes.
Some jurisdictions allow comparative or contributory negligence on the part of the insured to bar an action entirely against a broker. Others reject the defense as a matter of law, and a few jurisdictions offer a middle ground that gauges whether the insured acted reasonably in not reading its policy.
The bottom line, it is always important to read a contract thoroughly (which can be exhaustive at times) to avoid unpleasant surprises. An insurance policy is no different.
