Final answer:
Designated agency involves a managing broker designating agents to separately represent the seller and buyer in real estate transactions. Certain licensees, possibly including attorneys and unlicensed assistants, could be excluded from practicing designated agency. More context is needed to specify which licensee would be excepted.
Step-by-step explanation:
Within the context of real estate and business practices, designated agency refers to a situation where a managing broker of a real estate agency designates one agent to represent the seller and another to represent the buyer. This allows the brokerage to manage both sides of the transaction while maintaining the fiduciary duties to both clients. However, certain licensees may be excluded from engaging in designated agency due to conflicts of interest or regulatory restrictions. For example, attorneys, unlicensed assistants, and certain types of fiduciaries might not be allowed to act as designated agents.
Since it is not specified which types of licensees are being considered in the question, one cannot definitively answer who might be excluded without more context. Generally speaking, it is essential for licensees who engage in designated agency to be authorized to practice in that capacity, typically being licensed real estate agents or brokers.
