Final answer:
A real estate broker cannot attempt to establish an agency relationship with someone currently represented by another broker as per the NAR Code of Ethics and ORS 696.301, unless the current agreement is ended or the individual seeks new representation.
Step-by-step explanation:
According to the NAR Code of Ethics and ORS 696.301, a real estate broker is typically not allowed to establish an agency relationship with an individual who is already represented by another real estate broker unless the current representation agreement has expired or been terminated, or if the individual initiates a change to seek new representation. This ethical guideline is in place to respect the existing professional relationships between clients and their current brokers, and to maintain industry professional conduct standards. Attempting to interfere with an existing agency relationship could be considered a violation of the NAR Code of Ethics, which could result in disciplinary action.
