the contract did not close because of reasons not related to the property. the owner of the home has now approached me and asked me to list the property. yes, it is ok for you to represent the seller in this situation. however, you should make it clear to this new client that you cannot reveal to him any confidential information provided to you by your former client unless that client consents to the release of that information to the seller. thus, if you had obtained material information about the property while representing your former buyer client, you would be required to disclose that information to the seller and any subsequent buyer of the property during your representation of the seller. is there a form i should give him to disclose that i represent the seller?
