Dual agency is an acceptable form of representation but because the agent has promised a duty of confidentiality, loyalty and full disclosure to both parties simultaneously, it is necessary to limit these duties in this situation, if both parties consent to dual agency law. This relationship involves the following limitations:
The Agent will deal with the Buyer and the Seller impartially
The Agent will have a duty of disclosure to both the Buyer and the Seller
The Agent will not disclose that the Buyer is willing to pay a price or agree to terms other than those contained in the Offer, or that the Seller is willing to accept a price or terms other than those contained in the Listing
The Agent will not disclose the motivation of the Buyer or the Seller to sell unless authorized by the Buyer or the Seller
The Agent will not disclose personal information about either the Buyer or the Seller unless authorized in writing
The Agent will disclose to the Buyer the defects about the physical condition of the Property known to the Agent
I realize you asked this question quite a long time ago but I would love to hear how the situation turned out.
However you shouldn't have to go that far. If you just explain the situation to the manager, I am sure they will release you. If not, get your attorney involved.
Hope this helps.....
