In Queensland, an agent enters into a dual agency arrangement representing both vendor and purchaser in the same transaction. Which statement is correct regarding disclosure requirements?

Option A: Disclosure is only required to the vendor as they pay the commission

Option A is incorrect because disclosure obligations extend to all parties in the dual agency relationship, not just the commission-paying vendor. Both vendor and purchaser have the right to know about potential conflicts of interest, regardless of who pays the agent's commission.

Option C: Disclosure is not required if both parties are sophisticated commercial clients

Option C is incorrect because the disclosure requirement applies to all dual agency arrangements regardless of the parties' commercial sophistication. Even experienced commercial clients are entitled to written disclosure about potential conflicts of interest inherent in dual representation.

Option D: Verbal disclosure at settlement is sufficient

Option D is incorrect because verbal disclosure at settlement is both insufficient in format and too late in timing. Queensland legislation requires written disclosure, and it must be provided before entering the dual agency arrangement, not at the conclusion of the transaction.
