Delve into how principal-agent relationships are formed, including express, implied, and apparent authority, with practical case studies and diagrams that illustrate key elements of agency law.
Agency law is a foundational component of business law and significantly influences professional practice, particularly for CPAs who handle engagements involving contractual arrangements, liability exposures, and client representation. At its core, an agency relationship enables one party (the “agent”) to take actions that legally bind another party (the “principal”). Below, we examine essential principles related to agency formation, types of agency relationships (including express, implied, and apparent authority), and the key legal and practical considerations that guide these arrangements.
A principal-agent relationship is created when a principal authorizes an agent to act on their behalf in dealings with third parties. Once formed, the agency relationship obligates the principal to honor agreements, transactions, and legal commitments made by the agent within the scope of the agent’s authority. Similarly, agents assume certain fiduciary duties to their principals, most notably loyalty and care. Understanding how these relationships begin and the types of authority conferred is crucial for legal compliance, effective governance, and mitigating risk.
Key elements of a valid principal-agent relationship often include:
• Mutual Consent: Both principal and agent must voluntarily consent to the relationship.
• Control: The principal has the right to control the agent’s actions.
• Purpose: The agent’s actions must be undertaken for the benefit of the principal.
It is not always necessary for an agency relationship to be formalized in writing (although some statutes may require a written agreement). Agency may exist based on behavior, communication, and other contextual factors that show the parties’ intent.
CPA candidates should master the key aspects of agency law because business law concepts are tested in the Regulation (REG) section of the Uniform CPA Examination. Agency relationships intersect with contracts, torts, and liability principles. For instance, the agent’s authority might determine whether a contract is binding on a corporation or whether an individual partner can commit a partnership to a loan. Understanding these concepts will also reinforce strategies for limiting exposure to malpractice claims and ensuring compliance in various professional engagements (refer to Chapters 3 and 6 for additional references on ethics, responsibilities, and legal duties).
Authority is the crux of an agency relationship; it defines the agent’s rights and powers to bind the principal. While we often think of “authority” as an explicit, well-drafted document or contract, agency law recognizes multiple ways by which authority may arise.
Express authority is explicitly conferred upon an agent by the principal, typically through written or oral agreements. This authority is straightforward to identify because the principal unequivocally states what the agent can (and sometimes cannot) do on their behalf.
• Example: A homeowner gives written instructions to a realtor granting the realtor the power to list the house for sale at a specified price. The homeowner is the principal, and the realtor is the agent with express authority to conduct real estate listing activities.
Express authority is typically articulated in engagement letters, contracts, partnership agreements, or corporate resolutions. The clarity of written instructions helps avoid confusion regarding the scope of the agent’s activities.
Implied authority extends from express authority and is based on the agent’s reasonable belief that certain actions are necessary to accomplish the objectives that the principal assigned. While not directly articulated, implied authority often flows from industry customs, status, or from typical business practices.
• Example: A principal gives an agent express authority to manage a factory’s supply chain. Though the contract does not say the agent can negotiate shipping prices, the agent reasonably concludes they have implied authority to negotiate such terms to carry out their express authority to keep production flowing.
Implied authority can emerge from a job title, from necessity, or from circumstances where failing to exercise certain powers would obstruct the agent’s primary functions. This concept is pivotal for CPAs and controllers who have “implied authority” to undertake financial and operational tasks necessary for fulfilling their fiduciary duties.
Apparent authority arises when the principal’s words or actions lead a third party to believe that the agent has authority—even if the principal and the agent never explicitly established such authority. Under the legal principle of estoppel, if the principal creates an impression that an individual is their agent, the principal can be bound by that individual’s actions if a third party relied on that representation.
• Example: A manager in a corporate office introduces a former employee as the company’s “top negotiator.” Even though that individual no longer works for the company, their statement could create apparent authority if a third party reasonably believes the introduction is valid. The company could be obliged to honor deals made by the so-called “negotiator.”
Apparent authority underscores the significance of carefully managing public representations, job titles, and employee transitions. A misstep in communication, such as failing to update clients about an employee’s departure, may trigger unintended and costly legal ramifications.
By Agreement: The most typical way to form an agency relationship is via contract (written or oral). Both parties consent—one to act on another’s behalf, and the other to delegate a scope of authority. This arrangement is generally subject to the same requirements for a valid contract: offer, acceptance, consideration, and the absence of any statutory or common law limitations.
By Ratification: Even if an agent acts without proper authority, the principal can retrospectively approve or “ratify” the act. Once the principal ratifies that act, the transaction is treated as if the agent possessed the authority at the time. Ratification can be explicit or implied (for instance, when a principal knowingly accepts the benefits of the unauthorized transaction).
By Operation of Law: In special cases—such as an emergency where immediate decisions are required to protect the principal’s interests—an agency relationship can be created by operation of law. For example, if a hotel manager (agent) is away, an assistant manager might have the legal authority to manage an urgent expense to protect business property from imminent damage, even if that level of spending was not explicitly sanctioned.
Although the institutional structure of an agency relationship focuses on authority, underlying this arrangement is a fiduciary bond. Fiduciary duties obligate agents to act in the principal’s best interest, avoid conflicts of interest, maintain confidentiality, and exercise reasonable care and skill.
Conversely, the principal also has duties to the agent:
• Duty to Compensate (if applicable).
• Duty to Reimburse and Indemnify for authorized expenses and liabilities incurred.
• Duty to Cooperate so that the agent can fulfill their responsibilities.
Professionals, including CPAs, who act in an agency capacity for their clients must pay particular attention to these fiduciary obligations. A breach could lead to malpractice issues (see Chapter 6).
A small business owner (the principal) grants a commercial real estate broker (the agent) express authority to negotiate a five-year lease on a new office building. The broker explicitly outlines the maximum rent per square foot they can agree upon, as well as other conditions such as renewal options. Because these parameters are set in writing, the broker’s authority is clearly defined. If the broker negotiates a higher rate than authorized, the principal might refuse to honor the contract—or choose to ratify it.
A distribution manager (the agent) is responsible for ensuring continuous stock levels of a popular soft drink. While the principal has not explicitly stated that the manager can secure storage waivers or short-term warehousing solutions, such arrangements are implied if they are necessary to keep the supply chain running. If local ordinances require special storage approvals and the manager obtains them, that act may be deemed within the agent’s implied authority.
A tech startup’s founder (the principal) is frequently seen at public events with their “operations consultant,” giving updates about the company’s strategic moves. The founder’s statements—“they’re running the operations side for us”—could create an impression among venture capitalists that the consultant can finalize partnership agreements. Even if the consultant’s actual authority is limited to preparing internal operational schedules, the repeated public statements might lead prospective partners to rely on the consultant’s signature or assurances. If those partners proceed in good faith, the founder could be bound by the consultant’s actions under apparent authority.
Forming and maintaining an agency relationship can trigger various legal and financial risks. Below are some critical pitfalls and best practices to help avoid unintended liabilities:
• Insufficient Documentation: Relying purely on oral agreements or ambiguous communications can lead to disputes over the scope of authority. ► Best Practice: Create clear contracts or engagement letters specifying the agent’s duties and limits of authority.
• Unclear Job Titles and Public Representations: Overly broad or misleading titles may inadvertently create apparent authority. ► Best Practice: Maintain accurate organizational charts and notify clients promptly when an employee’s role changes or they leave the company.
• Scope Creep in Implied Authority: Agents might assume tasks beyond the principal’s expectations. ► Best Practice: Regularly review the agent’s responsibilities, and if needed, update instructions or provide clarifications in writing.
• Failure to Communicate: Principals who do not promptly update agents on material changes, or agents who do not disclose critical facts to principals, can cause major legal or financial exposure. ► Best Practice: Establish a consistent reporting mechanism and document important decisions.
• Not Recognizing Ratification Risks: Principals sometimes inadvertently ratify unauthorized acts by accepting benefits (e.g., using funds obtained through an unauthorized loan). ► Best Practice: Promptly examine the actions of agents and decide whether to reject or accept those actions in writing.
By following these best practices, CPAs and other professionals minimize misunderstandings and reduce the likelihood of litigation stemming from unauthorized or improperly documented activities.

As shown:
• The principal intentionally grants express authority.
• Implied authority constructs the “in-between” space—actions necessary to fulfill express instructions.
• Statements creating apparent authority may lead a third party to bind the principal.
Understanding the formation of an agency relationship lays the foundation for deeper exploration of 7.2 Authority of Agents and Principals (Actual, Apparent, Ratification) and 7.3 Duties and Liabilities of Agents and Principals. Subsequent sections will discuss how an agent’s actions can bind or expose the principal to liabilities and how duties like loyalty, obedience, and confidentiality interplay with corporate governance, contract law, and tort law. Additionally, concepts found here will dovetail with discussions in Chapter 8: Contracts, as agents often negotiate or finalize contractual relationships on behalf of principals.
