Fiduciary

Definition

Involving trust, especially with regard to the relationship between a trustee and a beneficiary.

Deep Dive

A fiduciary describes a relationship founded on trust and confidence, where one party (the fiduciary) is entrusted to act in the best interests of another party (the beneficiary or principal). This duty is one of the highest standards of care recognized in law, requiring the fiduciary to prioritize the beneficiary's interests above their own and to avoid conflicts of interest. Fiduciary relationships are prevalent in many professional and business contexts, including those between a trustee and beneficiary, a corporate director and shareholders, an attorney and client, or a financial advisor and their investor clients. The core obligation is loyalty and utmost good faith.
