For the purposes of this chapter, an “independent insurance producer” means any licensed property and casualty insurance producer representing a property and casualty insurance company on an independent contractor basis and not as an employee. This term includes only those producers not obligated by contract to place property and casualty insurance accounts with any insurance company or group of companies. This chapter only applies to contracts which have been in effect for more than one year between an independent insurance producer and a property and casualty insurance company.
