A seller's agent WORKS ONLY FOR THE SELLER and has legal obligations, called fiduciary duties, to the seller. These include reasonable care, undivided loyalty, confidentiality and full disclosure. Seller's agents often work with buyers, but do not represent the buyer's. However, in working with buyers a seller's agent must act honestly. In dealing with both parties, a seller's agent may not make any misrepresentations to either party on matters material to the transaction, such as the buyer's financial ability to pay, and must disclose defects of a material nature affecting the physical condition of the property which a reasonable inspection by the
licensee would disclose.

Seller's agents include all persons licensed with the brokerage firm which has been authorized through a listing agreement to work as the seller's agent. In addition, other brokerage firms may accept an offer to work with the listing broker's firm as the seller's agents. In such cases, those firms and all persons licensed with such firms are called "sub-agents." Sellers who do not desire to have their property marketed through sub-agents should so inform the seller's agent.
