What is the term for an individual who has a fiduciary duty to perform?

The correct answer is the term "Fiduciary." A fiduciary is an individual or entity that has the legal and ethical responsibility to act in the best interest of another party. This relationship typically involves a high degree of trust and reliance, often characterized by a duty to manage or protect someone else's assets or interests. The fiduciary duty requires the individual to prioritize the interests of the party they represent, ensuring decisions are made with care and honesty.

While an agent acts on behalf of another individual (known as the principal) and can also have fiduciary duties, the term "fiduciary" encompasses a broader context that includes various relationships such as those between trustees and beneficiaries. A trustee, for instance, manages assets held in trust for another (the beneficiary), creating a fiduciary relationship, but this term specifies a particular role within that relationship. The beneficiary is the individual or group that benefits from the actions of the fiduciary and does not perform duties themselves. Thus, the designation of "fiduciary" accurately captures the essence of the duty to perform on behalf of another party.
