Fiduciary Duties and Duties to Customers

In this lesson you will
  • Differentiate between a client and a customer, explaining how agency relationships are established under a supervising broker.
  • Identify and apply the six fiduciary duties represented by the acronym OLD CAR in real estate practice.
  • Distinguish the duties owed to represented clients from the honesty, fair dealing, and disclosure obligations owed to unrepresented customers.

The Agency Framework: Clients, Customers, and Representation

In real estate practice, understanding the exact nature of your professional relationships is essential. A fiduciary relationship is a relationship of trust and confidence formed between an agent and a principal. In this context, a client is a principal who is represented by a real estate brokerage through an agency relationship, established as permitted by state law. By contrast, a customer receives real estate services without being represented as a client; depending on state law, an agency relationship may arise without a written representation agreement.

A real estate salesperson does not operate entirely independently; a salesperson works under a supervising broker and acts on that brokerage's behalf. Whether and how a salesperson establishes an agency relationship with a client depends on applicable state law and the specific agency arrangements maintained by the brokerage. Because specific agency statutes and legal definitions vary from state to state, candidates must recognize that these principles originate in common law and evolving statutory standards.

The distinction between a client and a customer governs the scope of duties an agent must deliver. Licensees do not owe fiduciary duties to third-party customers. Instead, licensees generally owe customers honesty, fair dealing, and the disclosure of facts required by applicable law, even without an agency relationship. When working with an unrepresented customer, a licensee must clarify whom the brokerage represents and avoid acting as that customer's advocate unless an agency relationship is established as permitted by state law. Because agency disclosure requirements, including their exact format and timing, vary by state, licensees must disclose whom they represent strictly as required by applicable law.

Common mistakes

  • Believing that the fiduciary duty of obedience requires following any client directive, overlooking that an agent must refuse unlawful instructions such as fair housing violations or hiding required defect disclosures.
  • Assuming that the duty of confidentiality terminates once a sale closes or the representation agreement expires, when confidentiality legally survives both events.
  • Thinking that an 'as is' clause in a purchase agreement relieves an agent from the legal obligation to disclose known material property defects.
  • Confusing commingling (mixing entrusted client or customer funds with personal or business funds) with conversion (the illegal spending or unauthorized use of those funds).

Key points

  • A fiduciary relationship is built on trust and confidence between an agent and a client (principal); customers receive services without representation.
  • A salesperson operates under a supervising broker, acting on the brokerage's behalf according to state law and the firm's agency arrangements.
  • The acronym OLD CAR outlines the six core fiduciary duties: Obedience, Loyalty, Disclosure, Confidentiality, Accounting, and Reasonable Care.
  • Obedience is limited to lawful instructions, loyalty prohibits undisclosed self-dealing and secret profits, and confidentiality survives transaction closing and agency termination.
  • Commingling is the improper mixing of entrusted funds, while conversion is the unlawful spending or unauthorized use of those funds.
  • Licensees owe customers honesty and fair dealing and must disclose known material adverse property facts, including latent defects, as required by applicable state law.
  • Puffing is legal subjective exaggeration, whereas misrepresentation involves false statements or omissions of material fact through negligence or fraud.
