ETHICSearch is a free legal ethics research service for members of the American Bar Association provided through the ABA Center for Professional Responsibility. Non-ABA members can subscribe to the service annually.
Call the Ethics Line to talk to the Washington State Bar Association Professional Responsibility Counsel, who can "help you analyze the ethical issues involved to enable you to make a decision consistent with the requirements of the Rules of Professional Conduct (RPC)." The counsel offers "confidential, informal guidance as to your own prospective ethical conduct." For more information, see this page.
