Which of the following is NOT a duty outlined in the NAR Code of Ethics?

The NAR (National Association of Realtors) Code of Ethics includes various duties that real estate professionals owe to different parties in the course of their business. Among these, there are clear responsibilities established that realtors must uphold towards their clients and customers, the public, and other licensees.

Duties to clients and customers encompass obligations like loyalty, disclosure, and accountability, ensuring that the interests of those clients and customers are prioritized. Duties to the public focus on the need for honesty and integrity in all dealings, as real estate professionals are expected to serve the broader community's interests and uphold the reputation of the profession. Duties to other licensees involve maintaining respect and ethical conduct within the industry, which promotes healthy competition and collaboration among real estate professionals.

However, the Code itself does not explicitly outline "duties to competitors" as a defined category. While professional courtesy and ethical conduct towards competitors are encouraged, these are not formalized into distinct duties within the NAR Code. Thus, recognizing that duties to competitors do not exist as a separate guideline elucidates why this option stands apart from the others present in the question.
