When an attorney, for whatever reason-sloth, over zealous conduct, or personal greed-represents a client without being completely loyal to the client's interests there are several things that may occur. The attorney may be subject to disciplinary or disbarment proceedings. He may be disqualified from further representing his client. If the attorney's actions have resulted in damage to his client the attorney may find himself the defendant in a malpractice action. If the cause of the damage is alleged to be the result of an attorney representing dual interests or improperly representing adverse interests then the cause of action will be for representing conflicting interests.
