What agency is
An agency relationship is created by conduct and consent, never by payment. Here is how it forms, the duties it creates, and how it ends.
Fiduciary representation
Agency is a legal relationship in which one party, the agent, acts on behalf of another, the principal, with authority to affect the principal’s interests. In real estate the brokerage is the agent and the client is the principal, with individual licensees acting through the firm. That structure is why the broker of record carries responsibility for what agents do.
The six duties
Loyalty, confidentiality, obedience, disclosure, reasonable care and accounting. Each attaches on formation and each is a place where a file gets judged later. The single agency guide carries the plain operational meaning of all six.
Agency is not employment
Most agents are independent contractors of their brokerage, and that has nothing to do with the agency relationship the firm holds with a client. One is a tax and labor classification between the firm and the licensee. The other is a fiduciary relationship between the firm and the consumer. Confusing them produces bad answers to supervision questions.
The client is the firm’s, not the agent’s
Agreements are signed with the brokerage. When an agent leaves, the relationship stays with the firm unless the client releases it, which is why departure disputes turn on the paperwork rather than the personal rapport.
How agency is created
Express agreement is the norm. Implied agency is the risk. Payment creates nothing.
How agency is created, and what proves it
| Status | What creates it | The evidence |
|---|---|---|
| Express agency | A signed listing agreement, buyer representation agreement, or written appointment naming the client and the term | The document itself, dated and signed by both parties |
| Implied agency | Conduct that a reasonable person reads as representation: advising on price, negotiating strategy, holding confidences | Emails, texts, showing records and testimony about what the licensee actually did |
| No agency | Customer service only: factual answers, access to the property, disclosure of known material defects | A signed disclosure stating who the firm represents, plus conduct that stayed inside the customer line |

The express route
A listing agreement or a buyer representation agreement names the client, the property or search scope, the term and the compensation. Since August 2024, MLS participants working with a buyer need a written agreement before touring, so the express route now covers nearly every buyer relationship as well. The buyer agency agreement guide covers what those documents contain.
Why payment does not create agency
Compensation flows one way and duties flow another. A buyer agent compensated through the listing side represents the buyer. A seller paying a cooperating brokerage does not become that brokerage’s client. This distinction was true before 2024 and is more visible now that compensation is negotiated openly rather than published in the MLS.
Disclosure announces the relationship, it does not create it
The state agency disclosure form tells a consumer who represents whom. It is a notice, and the agreement is what forms the relationship. Both belong in the file, and a firm that has one without the other has a gap.
Implied agency and how brokerages get caught
Behaving like a representative creates the duties of one, whatever the paperwork says.
The conduct that does it
Advising an unrepresented buyer on what to offer. Telling them the seller is motivated. Suggesting an inspection strategy. Taking their confidences and keeping them. Each of these is advocacy, and a reasonable person on the receiving end concludes the licensee is working for them.
Why it happens
Almost never on purpose. An agent trying to be useful to a pleasant unrepresented buyer drifts across the line one helpful sentence at a time, and nobody in the conversation notices the moment it happens.
The exposure
Implied agency carries full duties with none of the protections. No signed scope, no agreed term, no compensation agreement, and often a direct conflict with the client the firm actually represents. Firms that keep agency documentation for brokerages consistent across every file catch the drift while it is still a conversation rather than a claim.
The fix is a sentence
Telling an unrepresented party plainly and early that the firm represents the other side, then getting the disclosure signed, resolves it. Agents who say it out loud once rarely have the problem twice.
The relationship types at a glance
Five arrangements cover nearly every transaction in the United States.
The relationship types at a glance
| Single agency | One client per transaction per brokerage, with the full fiduciary set intact |
| Dual agency | One licensee holds both sides, duties reduced by written consent, illegal in several states |
| Designated agency | Two licensees from one firm, one per side, each keeping full duties to their own client |
| Subagency | A cooperating agent representing the seller, largely historical and rarely offered today |
| Transaction brokerage | A non agency role in states that offer it, providing facilitation without fiduciary duties to either side |
Which one applies is a state question first
Dual agency is prohibited in several states, transaction brokerage exists only where the statute creates it, and terminology varies. Check the state rule before assuming the arrangement in front of you is available.
And a policy question second
Where a state permits several arrangements, the brokerage chooses which it practices and writes that into policy. Making the decision once at the firm level beats making it per transaction with a buyer standing in a kitchen.
How agency ends
Six ways, and one duty that outlasts all of them.
The ordinary endings
Completion of the purpose, which for most files is closing. Expiration of the stated term. Mutual release, signed by both parties. These three cover the overwhelming majority of terminations and produce no dispute if the document is in the file.
Revocation and renunciation
A principal can revoke the agency, and an agent can renounce it. Either ends the relationship, and neither necessarily ends the contract. A seller who fires a brokerage mid term may still owe compensation if a protection period applies and a buyer procured during the term later closes. The listing agreement guide covers those clauses.
Death or incapacity
Agency is personal and terminates on the death or legal incapacity of either party. An estate may sign a new agreement, and the old one does not carry over on its own.
What survives termination
| Duty | After termination | What that means |
|---|---|---|
| Confidentiality | Survives with no end date | A former client's motivation and price ceiling stay protected forever |
| Accounting | Survives until settled | Trust funds and documents must still be reconciled and delivered |
| Loyalty | Ends with the relationship | The firm may represent an adverse party in a later transaction |
| Obedience | Ends with the relationship | No duty to follow instructions from a former client |
| Disclosure to the client | Ends with the relationship | No duty to report new facts after termination |
| Reasonable care | Ends prospectively | Work already performed remains subject to a negligence claim |
Confidentiality is the one to remember
A former client’s motivation, financial position and price ceiling stay protected indefinitely, including when that person appears on the other side of a later deal. Firms get caught here years after the original file closed.
The record
Three documents describe the whole arc of an agency relationship.
The agreement that created it
Signed, dated, with a defined term and a named client. A file whose representation agreement is missing or unsigned has no clean answer to the question of who the firm worked for.
The disclosure that announced it
The state agency disclosure form, marked correctly and dated before the first substantive representation conversation. Timing matters as much as presence, and the disclosure timing guide covers the state rules.
The document that ended it
A settlement statement, an expiration, a signed release or a termination notice. Relationships that fade out without a record are the ones that produce arguments about whether a later commission was owed.
Check the three together
The agreement, the disclosure and the file should all name the same client. Internal contradiction between them is what an examiner finds first, and it is a check that takes under a minute during a broker file review.
Questions brokers ask
How is an agency relationship created?
By agreement between a principal and an agent, expressed in writing in almost every professional transaction and capable of forming by conduct where no document exists. A signed listing agreement or buyer representation agreement creates it expressly. Acting like someone's representative, advising them on price and negotiating for them, can create it by implication even with nothing signed. Consent plus conduct forms the relationship, and courts look at what actually happened.
Does paying an agent create agency?
No. Compensation and representation are separate questions, and this has been settled law for decades. A buyer agent paid from the listing side still represents the buyer. A referral fee creates no duty to the payer. After the 2024 practice changes made compensation more openly negotiated, the point matters more, because who pays varies transaction to transaction while who represents whom is set by the agreement.
What duties does an agency relationship create?
Six fiduciary duties: loyalty, confidentiality, obedience to lawful instructions, disclosure of known material facts, reasonable care and skill, and accounting for money and documents. They run to the client for the life of the relationship, and confidentiality continues after it ends. Dual agency reduces several of them by consent, and designated agency preserves them within each appointment.
Can agency be created accidentally?
Yes, and it is one of the more common ways brokerages get exposed. An agent who advises an unrepresented buyer on what to offer, tells them a seller would take less, or holds their confidences is behaving as their representative regardless of paperwork. If a dispute follows, the question is what the licensee did rather than what was signed, and implied agency carries the same duties as the express version with none of the documentation.
How does an agency relationship end?
Completion of the purpose, expiration of the term, mutual release, revocation by the principal, renunciation by the agent, or death or incapacity of either party. Most relationships end quietly at closing or expiration. Revocation before the term ends terminates the agency but may leave contractual obligations such as a protection period intact. Confidentiality survives every one of these endings without an expiration date.
