In order to state a cause of action to recover damages for legal malpractice, the plaintiff must allege that the attorney failed to exercise the ordinary reasonable skill and knowledge commonly possessed by a member of the legal profession, and that the attorney's breach of this duty proximately caused the plaintiff to sustain actual and ascertainable damages. In order to establish causation, the plaintiff must plead specific factual allegations demonstrating that, but for the attorney's negligence, the underlying action would have had a more favorable outcome than resulted Conclusory allegations of damages or injuries predicated on speculation cannot suffice for a malpractice action, and dismissal is warranted where the allegations in the complaint are merely conclusory and speculative.
