If the insurane policy is direct bill, most are, there is no feduciary responsiblity...only moral... It is the responsibility of the underwriting department of the insurance company to notify you of a non-renewal for cause. The agent bears no responsibility for this. If you feel that you did not get proper notification per your state's regulations you can make a formal protest. If your non-renewal was for non-payment of a premium then your late notice would include a notice of the policy termination date.
