Lawyers who receives an unsolicited communication from a prospective client may represent another client in the same matter against the prospective client. Ass’n of Bar of City of New York Opinion 2001-1.  (March 2001).   Where the web site does not adequately warn that information transmitted to the lawyer or firm will not be treated as confidential, the information should be held in confidence by the lawyer receiving the communication and not disclosed to or used for the benefit of the other client even though the lawyer declines to represent the potential client.
