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 accurately account for all funds and property entrusted to them by the principal (the seller). While important, this duty does not pertain to the information shared with third parties and does not restrict the broker from disclosing personal circumstances of the seller.

The duty of disclosure refers to the broker's obligation to inform the seller about important facts that could affect the transaction. This duty protects the seller but does not restrict the broker from informally communicating non-sensitive information to buyers. Therefore, it does not apply in this situation where confidentiality is at stake.

Obedience requires the broker to follow the lawful instructions of the seller. While the broker must obey the seller's wishes, this duty does not prevent the broker from disclosing information; rather, it obligates the broker to act according to the seller's directions, which can include maintaining confidentiality.
