Which of the following is the most contractual, least fiduciary relationship?

• A. Guardianship
• B. Executorship
• C. Agency
• D. Trustee

Answer: (C)

Agency is rooted in a contract between two parties: the principal authorizes the agent to act on the principal’s behalf within defined authority. Because the relationship hinges on an agreement, its core framework is contractual—you set the scope, duties, and limits in the contract, and you can modify or end it by changing or terminating the agreement. The fiduciary duty still exists in agency—loyalty, keeping the principal’s interests ahead of the agent’s own and avoiding conflicts—but those duties arise within the bounds of the contract and the agent’s authority, not from a court or trust instrument.

In contrast, guardianship, executorship, and trustee relationships are shaped by law or trust terms and imposed to protect someone else’s welfare or assets. Guardianship is a court-appointed duty to care for a ward, with strict, ongoing fiduciary obligations. An executorship is the estate administrator’s role, governed by probate law and owed to creditors and beneficiaries. A trustee manages a trust under a trust document, with broad fiduciary duties of loyalty and prudent management. These roles are defined by law and duty to beneficiaries, not primarily by contract.

So, while all involve acting for another, the agency relationship is primarily contractual in origin and structure, making it the most contractual and comparatively less fiduciary in its foundation than the other options.
