REALTORS® are different from non-member licensees in that they voluntarily subscribe to a strict Code of Ethics.
In addition, REALTORS® agree as a condition of membership to arbitrate contractual disputes and specific non-contractual disputes as provided for in Article 17 of the National Association of REALTORS® (NAR) Code of Ethics.
NAR provides several resources to help you understand what filing and processing an ethics complaint and arbitration request entails, and the general process you can expect when filing an ethics complaint.
