What is agency in real estate? A complete guide to agent representation

If you’re preparing for a real estate career, few concepts are more important to understand than agency. Agency defines your relationship with a client and establishes who you represent in a transaction. It also determines the legal responsibilities you owe that client, including acting in their best interests, protecting confidential information, and fulfilling your legal and ethical obligations throughout the transaction.
The good news is that once you understand agency, many other real estate concepts become easier to understand. It’s also one of the most heavily tested topics on state licensing exams.

In this guide, you’ll learn what agency in real estate means, how agency relationships are formed, the different types of agency, fiduciary duties, disclosure requirements, and how recent industry changes have affected agent representation.

Key takeaways

  • Agency Creates a Legal Relationship: Agency establishes a legally binding relationship between a real estate professional and a client.
  • Fiduciary Duties Drive Representation: Once agency is established, agents owe specific duties, including loyalty, confidentiality, disclosure, obedience, reasonable care, and accounting.
  • Different Agency Types Require Different Responsibilities: Single agency, dual agency, designated agency, and transaction brokerage each have unique legal and ethical requirements.
  • Proper Disclosure Is Essential: Understanding and documenting agency relationships is a critical part of real estate compliance.
  • Agency Knowledge Supports Exam Success and Career Growth: Agency is a core licensing exam topic and a fundamental part of ethical real estate practice.

What is agency in real estate?

Agency in real estate is a legally binding relationship between a real estate professional and a client, known as the principal. Once this relationship is established, the agent owes the client fiduciary duties. These duties include loyalty, confidentiality, disclosure, obedience, reasonable care, and accounting. The agent must act in the client’s best interests while following the law.

Once you’re licensed, agency is more than just a legal concept. It serves as the foundation for how you’ll work with buyers and sellers throughout your career. Understanding agency helps you determine:

  • Who you represent in a transaction
  • What information must remain confidential
  • What disclosures are required
  • How you can ethically negotiate on behalf of clients
  • What responsibilities and duties you’re legally required to fulfill under your state’s agency laws

Because agency creates a relationship of trust, agents who fail to understand their responsibilities can face disciplinary action, legal liability, and damage to their professional reputation.

How does agency work in real estate transactions?

It’s important to understand how agency relationships are formed and managed.

Many new agents are surprised to learn that agency relationships can sometimes be created before a formal contract is signed. Depending on state law, agency may be created through written agreements, conversations, conduct, or actions that cause a consumer to reasonably believe they are being represented.

Once agency is established, the relationship becomes legally binding. The agent must fulfill fiduciary duties and follow all applicable agency laws. The client also has responsibilities under the representation agreement.

Understanding disclosure requirements and brokerage policies is critical. Agents must clearly explain who they represent, provide required disclosures, and properly document the relationship.

Agency typically begins when a buyer or seller agrees to be represented by a real estate professional. In many cases, this occurs through a listing agreement or buyer representation agreement. Some states also recognize implied agency relationships.

Agency generally ends when the transaction closes, the agreement expires, the relationship is legally terminated, or the purpose of the agency has been fulfilled. Even after agency ends, some duties, such as confidentiality, may continue under state law.

What are the different types of agency relationships?

Different agency relationships create different duties, disclosure requirements, and potential conflicts of interest.

If you’re studying agency for your licensing exam, this video provides a helpful overview of the most common agency relationships you’ll encounter as a real estate professional.


Before diving into each relationship type, it can be helpful to compare them side by side.

Agency TypeWho Is RepresentedFiduciary Duties Owed?Common Use
Single AgencyOne party onlyYesMost common form of representation
Dual AgencyBuyer and sellerLimited due to conflict of interestAllowed only in some states
Designated AgencySeparate clients represented by different agents within one brokerageYesCommon in larger brokerages
Transaction Broker/FacilitatorAssists both parties without representing either as a clientNo traditional fiduciary dutiesUsed in states recognizing transaction brokerage


Single agency (buyer or seller representation)

Single agency occurs when a real estate professional represents only one party in a transaction, either the buyer or the seller.

This form of representation is often considered the clearest and most straightforward agency relationship because the agent owes complete loyalty to one client.

Benefits of single agency include:

  • Undivided loyalty to one client
  • Strong confidentiality protections
  • Full advocacy during negotiations
  • Reduced conflicts of interest
  • Clear fiduciary obligations

For example, a buyer’s agent focuses exclusively on helping a buyer locate suitable properties, negotiate favorable terms, and protect confidential information. Likewise, a listing agent works solely to advance the seller’s interests.

Because the agent represents only one party, single agency is often viewed as providing the strongest level of client advocacy.

Dual agency

Dual agency occurs when one agent or brokerage represents both the buyer and seller in the same transaction.
Dual agency may occur when:

  • A single agent works with both parties
  • A brokerage represents both parties under state law
  • A buyer and seller choose to proceed with shared representation

The challenge with dual agency is that both parties have competing interests. Buyers generally want the lowest price and most favorable terms, while sellers typically seek the opposite.

As a result, dual agents generally cannot:

  • Advocate fully for either party
  • Reveal confidential pricing information
  • Suggest negotiating strategies that favor one side
  • Share motivations or financial information without permission

Because of these limitations, most states require informed written consent from all parties before dual agency can occur.

Several states, including Alaska, Colorado, Florida, Kansas, and Maryland, have restricted or prohibited traditional dual agency models and instead rely on other forms of representation, such as designated agency or transaction brokerage, that are designed to reduce conflicts of interest.

Designated agency

Designated agency is designed to reduce some of the challenges associated with dual agency.

Under designated agency:

  • One brokerage represents both parties
  • Separate agents are assigned to each client
  • Each agent owes fiduciary duties to their assigned client

For example, one agent in a brokerage may represent the seller while another agent from the same brokerage represents the buyer.

Benefits of designated agency include:

  • Stronger client advocacy than traditional dual agency
  • Greater confidentiality protections
  • Reduced conflicts of interest
  • Clear representation responsibilities

However, designated agency still requires careful supervision, disclosure, and compliance with state law because both agents remain affiliated with the same brokerage.

Transaction broker or facilitator

Some states recognize a non-agency relationship known as transaction brokerage or facilitation. In these arrangements, the transaction broker is typically a licensed real estate agent who assists both parties with the transaction without acting as a fiduciary for either side. The exact role and responsibilities of a transaction broker vary by state law.

Transaction brokers may:

  • Coordinate paperwork
  • Manage deadlines
  • Facilitate communication
  • Assist with administrative tasks
  • Help move the transaction toward closing

Unlike traditional agency relationships, transaction brokers generally do not provide advocacy, loyalty, or negotiation representation.
States such as Colorado and Florida have long used transaction brokerage models in various forms. Because laws vary significantly, agents should review their state’s requirements carefully.

What are the fiduciary duties in real estate agency?

Once an agency relationship is established, an agent assumes fiduciary responsibilities to their client. A fiduciary duty is the highest standard of care recognized by law and requires agents to place their clients’ interests above their own.

The six primary fiduciary duties are often tested on licensing exams and form the foundation of ethical real estate practice.

Fiduciary DutyWhat It Means
LoyaltyPut the client’s interests above your own
ConfidentialityProtect private client information
Disclosure Share material facts that could affect a client’s decisions
ObedienceFollow lawful client instructions
Reasonable CareProvide competent professional service
AccountingProperly handle money, documents, and property


These duties protect clients by ensuring they receive honest, competent, and ethical representation throughout a transaction.

Failing to uphold fiduciary duties can result in:

  • License discipline
  • Civil liability
  • Financial damages
  • Ethics complaints
  • Reputational harm

What fiduciary duties do buyer’s agents owe?

As a buyer’s agent, your role extends beyond helping clients find properties. You’re responsible for protecting your client’s interests throughout the transaction.

Key responsibilities include:

  • Advocating for the buyer during negotiations
  • Researching market conditions
  • Identifying suitable properties
  • Helping buyers evaluate properties through inspections, disclosures, and other due diligence activities
  • Explaining contracts and disclosures
  • Protecting confidential financial information
  • Disclosing material information affecting the transaction

Due diligence refers to the process of investigating and evaluating a property before completing the purchase. A buyer’s agent supports this process by helping clients gather information and understand potential risks.

Examples of due diligence activities include:

  • Reviewing property disclosures
  • Coordinating inspections
  • Helping buyers understand inspection reports
  • Researching zoning regulations, permits, or property restrictions
  • Identifying issues that could affect the property’s value or intended use
  • Tracking contingency deadlines in the purchase contract

What fiduciary duties do seller’s agents owe?

Seller’s agents have similar fiduciary responsibilities but focus on helping sellers achieve their goals.
Common responsibilities include:

  • Providing pricing guidance
  • Marketing the property
  • Presenting offers promptly
  • Negotiating favorable terms
  • Protecting confidential seller information
  • Advising on disclosure obligations
  • Communicating material information that may affect the sale

What are agency disclosure requirements?

One of the most important compliance responsibilities you’ll have as a real estate professional is properly disclosing agency relationships.
Agency disclosures help consumers understand:

  • Who you represent
  • What duties you owe
  • Whether dual agency exists
  • Any limitations on your representation

Most agency disclosure forms explain:

  • The type of agency relationship being established
  • The fiduciary duties owed to the client
  • Any dual agency or designated agency arrangements
  • Required consent provisions
  • The agent’s role in the transaction

Although requirements vary by state, written disclosures are generally preferred because they provide a clear record of the relationship and help prevent misunderstandings.

Best practices include:

  • Providing disclosures as early as possible
  • Using state-approved forms
  • Retaining signed copies
  • Maintaining transaction records according to brokerage policy
  • Reviewing disclosures with clients to confirm they understand their representation options

How do agency disclosure requirements vary by state?

Agency disclosure laws vary significantly across jurisdictions.
Examples include:

  • California requires a specific Agency Disclosure Form that explains representation options.
  • Colorado emphasizes transaction brokerage relationships and provides state-specific disclosures.
  • Florida prohibits traditional dual agency and requires alternative disclosure models.

Timing requirements also differ. Some states require disclosure at first substantive contact, while others require disclosure before a representation agreement is signed.

For current guidance, consult:

  • Your state real estate commission
  • State REALTOR® associations
  • Brokerage legal counsel
  • State association legal hotlines

Can you switch agency relationships mid-transaction?

Agency relationships sometimes change during a transaction. As an agent, you may encounter situations involving brokerage changes, client requests, reassignment of representation, or evolving transaction circumstances.

Whenever agency relationships change, proper documentation and disclosure are essential. Understanding how to navigate these transitions can help prevent misunderstandings, protect clients, and maintain compliance with state law.

Frequently asked questions about real estate agency

Is dual agency legal in my state?

As a future real estate agent, you’ll need to know your state’s specific rules regarding dual agency. Some states allow dual agency with informed written consent from both parties, while others restrict or prohibit it altogether. Always review your state’s real estate laws and brokerage policies before engaging in any dual agency arrangement.

What’s the difference between a client and a customer in real estate?

Understanding this distinction is essential for new agents. A client is someone you represent through an agency relationship and to whom you owe fiduciary duties. A customer, on the other hand, may receive limited services or assistance without the full protections and obligations that come with agency representation. The exact definitions vary by state.

Do I have to provide an agency disclosure form?

In many states, yes. Real estate agents are often required to provide agency disclosures that explain who they represent and what duties they owe. Requirements vary by jurisdiction, so it’s important to understand when disclosures must be delivered and what forms your state or brokerage requires.

Can I represent a client if I’m friends with the other party?

Possibly, but you must be careful to avoid conflicts of interest. Depending on the circumstances and state law, you may need to disclose the relationship to your client and other parties involved. Regardless of personal relationships, you must continue to fulfill your fiduciary duties and act in your client’s best interests.

What happens if an agent breaches their fiduciary duty?

Breaching a fiduciary duty can have serious consequences for a real estate professional. Depending on the situation, penalties may include disciplinary action by the state licensing authority, fines, civil lawsuits, monetary damages, or even license suspension or revocation. Understanding and fulfilling your fiduciary responsibilities is critical to building a successful and compliant real estate career.
