Agency
A legal relationship in which a licensee (agent) acts on behalf of a principal (buyer or seller) in a real estate transaction.
What Is Agency?
Agency is the legal relationship created when one person (the principal) authorizes another person (the agent) to act on their behalf in dealings with third parties. In real estate, agency arises when a buyer or seller (the principal) authorizes a licensed broker or salesperson (the agent) to represent their interests in a transaction. The agency relationship triggers fiduciary duties (OLD CAR: Obedience, Loyalty, Disclosure, Confidentiality, Accounting, Reasonable Care) that the agent owes to the principal. Agency can be created in several ways: express agency is formed through a written or oral agreement (most commonly a listing agreement for sellers or a buyer representation agreement for buyers); implied agency arises unintentionally from the conduct of the parties, even without a formal agreement — for example, when an agent begins actively advising a buyer without a signed agreement; and agency by ratification occurs when a principal accepts and affirms an agent's previously unauthorized actions. Agency can also be categorized by scope: a general agent has broad authority to act for the principal in an ongoing relationship (like a property manager), while a special agent has limited authority for a specific task or transaction (like a broker hired to sell a single property). Most real estate brokers act as special agents.
Agency in Practice
Sarah signs a buyer representation agreement with Agent Martinez, creating an express agency relationship. Agent Martinez now owes Sarah all six fiduciary duties. When they visit open houses together, Agent Martinez cannot reveal to the listing agent that Sarah is willing to pay above asking price — that would violate the duty of confidentiality. However, if a different buyer at the same open house asks Agent Martinez questions about the property, Agent Martinez owes that buyer only honesty and fair dealing — not fiduciary duties — because that buyer is a customer, not a client.
Why Agency Matters
Agency is the foundational concept of real estate licensing law. Every licensed real estate professional operates within agency relationships, and every exam dedicates a significant section (typically 10–15% of questions) to testing agency concepts. Understanding agency determines whom the agent represents, what duties the agent owes, what information must be kept confidential, and what disclosures are required. For practicing agents, agency mistakes — such as inadvertently creating an implied agency with a buyer the agent did not intend to represent, or failing to disclose dual agency — are among the most common sources of lawsuits and license complaints. The recent NAR settlement changes have further elevated the importance of clearly defined buyer agency agreements.
Key Factors That Affect Agency
- 1.Express agency (written agreement) is the safest and clearest form. Most states require or strongly recommend written agency agreements. After the 2024 NAR settlement, many MLSs now require signed buyer representation agreements before showing properties.
- 2.Implied agency is created by conduct, not paperwork. If an agent begins actively advising and advocating for a buyer without a signed agreement, the agent may have created an agency relationship — with full fiduciary obligations — unintentionally.
- 3.Agency disclosure is required in nearly every state. Agents must inform all parties of whom they represent before substantive discussions begin. Failure to disclose agency is a license law violation in most jurisdictions.
- 4.The principal-agent relationship creates vicarious liability. The broker (principal in the brokerage relationship) can be held legally responsible for the acts of their agents (salespersons) performed within the scope of the agency relationship.
- 5.Agency can be terminated by: completion of the purpose, expiration of the agreement term, mutual agreement, death or incapacity of either party, destruction of the property, or revocation by the principal (who may owe damages if revoking an exclusive agreement).
Common Mistakes With Agency
- ✗Confusing the agent with the salesperson. In most states, the agency relationship is between the broker and the principal. The salesperson works under the broker's license and acts on behalf of the broker. The broker is the agent; the salesperson is a subagent of the broker.
- ✗Creating implied agency unintentionally. Agents who begin advising, negotiating for, or advocating on behalf of a buyer without a signed agreement may create an implied agency — triggering fiduciary obligations they did not intend to assume.
- ✗Failing to distinguish between clients and customers. A client has an agency relationship and receives fiduciary duties. A customer does not have an agency relationship and receives only honesty and fair dealing. Many exam questions test this distinction.
- ✗Thinking agency always requires a written agreement. While express written agreements are preferred and often required, agency can also be created orally (express oral) or through conduct (implied). The absence of a written agreement does not necessarily mean no agency exists.
- ✗Not understanding that agency disclosure is mandatory. In most states, agents must disclose whom they represent before any substantive discussions. Failing to provide timely agency disclosure is a common license law violation.
Agency vs. Related Metrics
Agency is the legal relationship; fiduciary duties are the obligations that arise from that relationship. Without agency, there are no fiduciary duties. Agency is the container; OLD CAR is the content.
Standard agency involves one agent representing one party. Dual agency occurs when one agent (or brokerage) represents both parties, creating inherent conflicts. Dual agency requires additional disclosures and limits the agent's ability to advocate for either party.
A listing agreement is the specific written contract that creates an agency relationship between a seller and a broker. It is one form of express agency — the most common way agency is created on the seller side.
How Agency Appears on the Real Estate Exam
Common question types, tested concepts, and what to watch out for
Know the three ways agency is created: express (written or oral agreement), implied (conduct), and ratification (after-the-fact approval). Know the difference between general agent (broad ongoing authority — like a property manager) and special agent (limited to one task — like selling a property). Know that fiduciary duties flow from the agency relationship and are owed to the principal, not to customers. Agency questions appear on virtually every state real estate exam.
