THank you and feel free to contact me if I can be of service. 401 286 2571 http://www.sandybliven.com
I don't believe there is a standard form to terminate your buyer agency agreement with your Broker. If you are working with a real estate agent then you do need to discuss cancelling your agreement with the Broker or Office Manager because your contract is with the Brokerage firm not just the agent.
I suggest that you contact the Broker and discuss your reasons for why you wish to end your agreement. The Broker may choose to assign you to another agent in his office or may agree to cancel the agency agreement with you so that you can move on.
Hope that helps.
Good luck to you!
