What is Fiduciary Duty?

A fiduciary duty is a legal obligation requiring one party to place another’s interests above their own, acting with loyalty, care, and good faith. These duties arise in relationships built on trust and authority, and violations can lead to serious financial and legal consequences.

Fiduciary duty litigation involves claims against individuals or entities who failed to uphold those obligations, whether through negligence, misconduct, or self-dealing. In business and corporate settings, breaches often involve governance failures, undisclosed conflicts of interest, or decisions that harm the company or its stakeholders.
