22. Every broker or agent, whether in the course of his duties or not, who holds or intends to acquire, directly or indirectly, an interest in immovable property that is being purchased, sold or exchanged must, without delay and in writing, disclose his quality as broker or agent to the prospective contracting party, in the manner prescribed in the by-laws of the Association.
In case of failure to do so, the person entitled to such information may, as long as the contract evidencing the transaction has not been signed by the parties, withdraw, without penalty, from any offer or promise, whether accepted or not, concerning the immovable property, by sending or giving a written notice to the other party.
