As the Seller, when you're in the "receiving contracts" status, you do not have to disclose to anyone that you have any contracts in hand. For instance, I was receiving several contracts on a waterfront listing I had in Eastport. My client, who was an attorney, decided not to disclose to the potential buyers that we were in receipt of another contract. After a contract was accepted, the buyer who's contract was rejected was angry with me for not disclosing the existence of another contract. It is the Seller's decision, not the agent's, when and if something will be disclosed. There are different reasons why one would and would not want to disclose the existence of another contract.
