A fiduciary breach claim against an attorney alleges violation of the duties of loyalty, confidentiality, or candor, including undisclosed conflicts, self-dealing, and misuse of client information.
It is distinct from negligence and may support different remedies.

Why it Matters?
Plaintiffs plead fiduciary breach alongside malpractice because the remedies differ: fee forfeiture and disgorgement do not require proving the underlying case would have succeeded, which avoids the case-within-a-case burden entirely. That makes the characterization consequential. Defense arguments frequently address whether the conduct alleged is genuinely disloyalty or merely negligence relabeled to escape the causation requirement.
