Agency Relationships: Principal, Client and Customer

In this lesson you will
  • Distinguish between the legal roles and duties owed to a principal (client) versus a third party (customer).
  • Differentiate between universal, general, and special agency and recognize how authority is granted and exercised in real estate practice.
  • Identify the various methods by which an agency relationship is created and terminated, including exceptions for an agency coupled with an interest.

The Agency Framework: Principals, Agents, and Brokerage Roles

Agency is a fiduciary relationship in which one party authorizes another to act on their behalf in business dealings with third parties. A fiduciary relationship is a legal relationship founded on trust, confidence, and reliance. In this arrangement, the principal, or client, is the person or entity who authorizes an agent to act on their behalf. The agent is the person or entity authorized to act on behalf of the principal within the scope of the agency, while the third party is the person with whom the agent negotiates on behalf of the principal.

In real estate transactions, agency contracts follow a clear professional structure. The listing agreement or buyer representation contract is made directly with the supervising broker, not directly with the affiliated salesperson. Even though an affiliated salesperson may meet the client, conduct property tours, and handle day-to-day communications, the underlying legal contract belongs strictly to the supervising broker.

Under this framework, a real estate salesperson acts as a general agent of their sponsoring broker because they are authorized to conduct continuous business activities for that broker. When representing the broker's client in a real estate transaction, the affiliated salesperson acts through the supervising broker and may be treated as the client's subagent, subject to state law.

Exam tip. Exam questions often test who owns the client relationship. Always remember that representation contracts are made with the supervising broker, not the salesperson. If a salesperson changes firms or becomes incapacitated, the representation contract remains with the broker.

Clients vs. Customers: Duties and Distinctions

Understanding the difference between a client and a customer is critical in real estate practice. A client is a principal who has entered into an agency relationship with a broker and is owed full fiduciary duties. State law governs agency disclosures and specific licensee duties, and traditional fiduciary duties generally apply when a broker represents a client.

A customer, by contrast, is a third party in a real estate transaction who does not have an agency relationship with the broker. Licensees do not represent customers, but they still have legal responsibilities toward them. Licensees generally owe customers honesty and fair dealing, and they must disclose known material adverse facts as required by state law.

The line between the two roles is defined by fiduciary obligations. Licensees generally do not owe customers the fiduciary duties of loyalty, obedience, or client-level confidentiality, although state law may protect certain customer information. For example, a broker hosting an open house for a seller owes loyalty to the seller and must follow the seller's lawful instructions, while also meeting applicable disclosure and other legal duties. When unrepresented buyers walk through the door as customers, the broker must treat them honestly and disclose known material adverse facts, but the broker cannot give them the confidential loyalty owed to the seller.

Levels of Agency Authority: Universal, General, and Special Agents

Agency relationships are classified by the scope of authority the principal grants to the agent: universal, general, or special. A universal agent has broad authority to act for a principal in personal and business matters, within the limits of the authority granted and applicable law. Universal agency is generally established through a broad power of attorney appointing an attorney-in-fact, with specific legal requirements varying by state.

A general agent has the authority to represent the principal in a broad range of matters related to a specific trade or business. A property manager handling ongoing operations of an investment property typically acts as a general agent for the property owner. In the brokerage office, a real estate salesperson is a general agent of their supervising broker because they are authorized to conduct continuous business activities for that broker.

A special agent, also known as a limited agent, is authorized to represent the principal in a single specific act or business transaction. A real estate broker hired under a standard listing contract acts as a special agent for the seller, and a broker hired under an exclusive buyer representation agreement acts as a special agent for the buyer. A special agent generally cannot bind the principal to a contract unless the principal specifically grants that authority, and requirements for written authorization vary by state and transaction.

An agent's actions also depend on whether authority is actual or apparent. Actual authority is the authority that the principal intentionally gives to the agent, either expressly or impliedly. In contrast, apparent authority occurs when a principal leads a third party to believe an agent possesses authority that has not actually been granted.

Exam tip. Do not confuse the salesperson's role with the broker's role in a transaction. In a standard listing or buyer representation agreement, the broker is a special agent hired for that specific transaction. However, between the salesperson and their supervising broker, the salesperson is a general agent authorized for continuous business activities.

Creation of Agency and Compensation Misconceptions

An agency relationship can be formed in several ways. Express agency is created when the principal and agent explicitly declare their intentions and terms orally or in writing. Written agency agreements are preferred in real estate practice and are required by law in many states, though state laws vary.

Agency can also arise without an explicit agreement. Implied agency arises from the parties' conduct rather than an express agreement, where recognized by applicable law. For instance, a licensee's conduct, such as acting as an unrepresented customer's advocate, may create implied agency where state law recognizes it; however, providing information alone does not necessarily do so.

Agency can also be established after the fact or through reliance. Agency by ratification occurs when a principal, with knowledge of the material facts, approves an act performed on the principal's behalf without prior authority. Agency by estoppel, or ostensible agency, arises when a principal's actions lead a third party to reasonably believe that an agency relationship exists.

A widespread misconception is that money creates agency. In real estate law, payment of compensation alone does not create or determine an agency relationship. An agency relationship can exist without financial compensation, which is known as a gratuitous agency. Furthermore, a broker may receive compensation from someone other than the broker's client without becoming that person's agent, subject to applicable disclosure and consent requirements.

Termination of Agency and Surviving Obligations

An agency relationship can be terminated either by acts of the parties or by operation of law. Acts of the parties that terminate agency include full performance of the contract, such as closing the real estate transaction. An agency agreement also terminates automatically upon the expiration of the agreed-upon contract term, or when the principal and agent mutually agree to terminate the relationship before the expiration date.

The parties also hold unilateral powers to terminate, though exercising them can create liability. Except for an agency coupled with an interest, a principal generally has the power to revoke an agent's authority, although doing so without contractual justification may result in liability for breach. Similarly, an agent has the legal power to renounce an agency relationship, but doing so without legal cause may result in liability for breach of contract.

Termination by operation of law happens automatically under specific legal conditions. The death or legal incapacity of a principal or an individual broker generally terminates their agency by operation of law, subject to exceptions such as an agency coupled with an interest and applicable state law. However, the death or incapacity of an affiliated salesperson does not terminate an agency agreement between the supervising broker and the client. Additionally, while the death or incapacity of an individual supervising broker may terminate that broker's agency agreements, agreements held by a brokerage entity do not necessarily terminate; state law and the agreements govern. Agency also terminates by operation of law upon destruction or condemnation of the subject property if it makes the agency's purpose impossible to fulfill, or upon a change in the law making the purpose illegal. Bankruptcy of the principal or broker may affect or terminate an agency relationship depending on applicable law and the circumstances, though filing for bankruptcy does not necessarily terminate it automatically.

A key exception to standard termination rules is an agency coupled with an interest. This occurs when an agent has a property or security interest in the subject matter of the agency, beyond an expectation of compensation. A principal generally cannot revoke an agency coupled with an interest in a way that defeats the agent's protected interest, nor does it terminate upon the death or incapacity of the principal. Confidentiality generally survives termination of the agency relationship, but its duration and exceptions vary by state; disclosure may also be permitted with the former client's consent or as provided by law.

Exam tip. Remember the two major exceptions to standard termination rules: First, an agency coupled with an interest cannot be revoked by the principal to defeat that interest and survives the principal's death or incapacity. Second, confidentiality generally continues after agency terminates, but its duration and exceptions depend on state law.

Common mistakes

  • Assuming that compensation creates an agency relationship; compensation alone does not determine agency, and gratuitous agency can exist without any payment.
  • Believing that representation contracts belong to the salesperson; listing and buyer representation agreements are made with the supervising broker.
  • Thinking an affiliated salesperson's death or incapacity terminates the client's listing agreement; the contract is held by the supervising broker and remains intact.
  • Assuming that all duties end when an agency relationship terminates; confidentiality generally continues after termination, but its duration and exceptions vary by state, and disclosure may be allowed with the former client's consent or as provided by law.

Summary

  • Agency is a fiduciary relationship founded on trust, confidence, and reliance, where a principal authorizes an agent to act on their behalf with third parties.
  • Real estate representation agreements are made with the supervising broker, making the salesperson a general agent of the broker and potentially a subagent of the client under state law.
  • Clients are owed full traditional fiduciary duties, whereas customers are third parties owed honesty, fair dealing, and disclosure of known material adverse facts.
  • Agents are categorized as universal (broad authority via power of attorney), general (broad authority in a specific trade, like a property manager or affiliated salesperson), or special (limited to a specific act, like a listing broker).
  • Agency can be express, implied through conduct, ratified after an unauthorized act, or established by estoppel; compensation alone does not create or dictate agency.
  • Agency terminates by acts of the parties (performance, expiration, mutual agreement, revocation, or renunciation) or by operation of law (death/incapacity of principal or individual broker, destruction, illegality, or bankruptcy circumstances).
  • An agency coupled with an interest cannot be revoked to defeat the agent's interest and survives the principal's death or incapacity, while the duty of confidentiality survives standard agency termination.
