Fiduciary Duty
The legal obligation an agent owes a client to act in the client's best interest with loyalty, confidentiality, disclosure, obedience, accounting, and reasonable care.
The short answer
A fiduciary duty is the legal obligation an agent owes a client to put the client's interests first. Licensing courses teach six duties, remembered as OLDCAR: obedience, loyalty, disclosure, confidentiality, accounting and reasonable care.
Exam tip: following all of the client's lawful instructions is obedience. The duty is owed to clients, the people the agent represents; customers on the other side are owed honesty and disclosure of known material facts, not loyalty.
| Duty | What it requires | Example |
|---|---|---|
| Obedience | Follow the client's lawful instructions | Listing at the price the seller chooses, even against advice |
| Loyalty | Put the client's interests above everyone else's, including the agent's | Not steering a buyer to a listing that pays the agent more |
| Disclosure | Tell the client every material fact the agent knows | Passing on that the seller has had other offers |
| Confidentiality | Keep the client's private information private, even after the deal | Not revealing a buyer's top price to the seller |
| Accounting | Account for all money and documents handled | Depositing earnest money in the escrow account on time |
| Reasonable care | Use the skill and diligence a competent agent would | Checking the property's zoning before advising on it |
Fiduciary duty is the legal obligation an agent owes to the client they represent: to act in that client's best interest, even ahead of the agent's own. In real estate it arises from agency law, the body of rules that governs what happens when one person is authorized to act for another. The traditional duties are often summarized as loyalty, obedience to lawful instructions, disclosure of material information, confidentiality, accounting for funds and documents, and reasonable care and diligence. Together they define the difference between representing a client and merely working near a transaction.
For a new agent, fiduciary duty is not abstract legal theory; it shapes everyday decisions. It determines what you may tell the other side during negotiation, what you must tell your own client, how you handle a client's confidential motivation to sell, and what happens when your interests and your client's diverge. Many licensing complaints and lawsuits against agents trace back to fiduciary breaches such as failing to disclose something material or putting a quicker fee ahead of the client's outcome. Understanding these duties protects your clients and your license.
Agency law varies by state, including which duties are codified, how agency relationships are created and disclosed, and what non-agency relationships such as transaction brokerage look like where they are permitted. Your state real estate commission publishes the agency disclosure forms and rules that apply in your market, and your pre-licensing coursework will cover them. Confirm how and when your state requires agency relationships to be disclosed in writing, and how duties change in special situations such as dual agency.
