What type of agreement regulates the relationship where an agent represents a seller and a buyer?

The relationship where an agent represents both a seller and a buyer is best regulated by a Dual Agency Agreement. This agreement acknowledges that the agent is acting on behalf of both parties in the same transaction, allowing for a single agent to facilitate the deal while maintaining certain obligations to both the buyer and the seller.

In a Dual Agency Agreement, the agent must navigate potential conflicts of interest and ensure that both parties are treated fairly, as the agent cannot fully advocate for one party over the other due to the dual representation. This is crucial in maintaining transparency and ethical standards in real estate transactions.

The other types of agreements mentioned serve different purposes. An Exclusive Listing Agreement typically pertains to a seller authorizing an agent to sell their property. A Transaction Broker Agreement involves an agent facilitating a transaction without representing either party in a fiduciary capacity. A Co-Listing Agreement involves multiple agents working together to sell a property, but it does not address the issue of dual representation for both buyers and sellers. Thus, a Dual Agency Agreement is specifically designed for the scenario presented in the question.
