In a jurisdiction where the common law of agency governs real estate activities, a broker has a single agency relationship with the seller only. The seller needs to be out of the home quickly due to job relocation. The broker CANNOT tell the buyer that information because of which fiduciary duty?

The duty of accounting requires the broker to keep accurate records of all transactions and funds related to the agency. While important, it does not pertain to the sharing of confidential information with third parties. Accounting primarily focuses on financial integrity rather than the nondisclosure of personal circumstances.

The duty of disclosure requires the broker to inform the seller of any material facts that could affect their decision in the transaction. However, this duty does not give the broker the right to disclose the seller's personal and private information, such as their need for a quick sale due to relocation. Thus, it is not the primary reason the broker cannot share this information with the buyer.

The duty of obedience requires the broker to follow the lawful instructions of the seller. While the broker must obey the seller's wishes regarding the sale, this duty does not permit the broker to disclose confidential information. Therefore, it does not explain why the broker cannot share the seller's urgency with the buyer.
