Final answer:
The fair and impartial act by a broker when acting as an intermediary in the TRELA is appointing separate associate licensees to represent the seller and buyer.
Step-by-step explanation:
The fair and impartial act by a broker when acting as an intermediary in the TRELA (Texas Real Estate License Act) is appointing separate associate licensees to represent the seller and buyer. This ensures that each party has their own representative who can advocate for their best interests. By having separate representatives, the broker can maintain impartiality and avoid conflicts of interest.
On the other hand, having the broker directly represent both the seller and buyer would not be considered fair and impartial, as it can create a conflict of interest. The same applies to having the broker represent the seller and an associate licensee represent the buyer, as the broker still has direct involvement in the transaction.
Similarly, having the broker represent the buyer and an associate licensee represent the seller would not be fair and impartial, as it can lead to a biased representation for either party.
