How a Real Estate Agency Relationship Is Created and Ended

Agency can end by the parties' agreement or acts, expiration of the agreed term, completion of the authorized purpose or operation of law. Ending authority does not automatically erase every contract right, commission issue, confidentiality duty, accounting obligation or record requirement.

The exam answer in one table

The recurring exam move is to separate the agency relationship, the agent's authority, the employment contract and the section 443 disclosure. They interact, but they are not the same document or legal question.

Official source map

The Department of State's 77-hour salesperson curriculum expressly includes express and implied agency, seller and buyer agency, section 443 disclosure, dual agency and termination of agency. Real Property Law section 443 defines the residential roles, sets disclosure timing and states that the disclosure form is not a contract. It also preserves New York common-law agency rules.

The Department's March 2026 license-law compilation contains current regulations on compensation, authorization, delivery of signed instruments, salesperson association and automatic continuation of exclusive listings. New York's official court reports supply the common-law rules for consent, control, creation by written or oral agreement or conduct, completion of a limited purpose and termination. Sources were checked on August 27, 2026.

What facts create an agency relationship?

New York courts focus on substance. The basic elements are:

1. the principal manifests consent that the agent will act on the principal's behalf
2. the agent agrees to act
3. the agent's action is subject to the principal's control within the granted scope

The parties do not avoid agency merely by choosing a different label if their actual relationship has these features. The reverse is also true. Calling someone “my agent” does not prove an agency relationship without consent, action on another's behalf and the required measure of control.

Express agency

Express agency exists when the principal and agent directly communicate their agreement. The authority may be stated in a written agreement or, where the law does not require a particular writing, in an oral agreement.

Common real estate examples include:

• a seller engages a broker under a listing agreement
• a landlord authorizes a broker to market and lease an apartment
• a buyer engages a brokerage to locate property and negotiate on the buyer's behalf
• a tenant engages a brokerage to locate and negotiate a rental
• an owner hires a broker to manage property under a management agreement

The agreement should answer practical questions about scope:

• Who is the client?
• What property or search does the authority cover?
• What may the broker do?
• What decisions remain with the principal?
• Is the relationship exclusive or nonexclusive?
• When does it begin and end?
• How is compensation addressed?
• What happens after termination?

An agent receives only the authority actually granted, together with authority reasonably incidental to carrying out the assignment. A real estate broker generally has authority to market, communicate, present and negotiate as agreed. That does not mean the broker automatically has authority to sign a deed, contract or lease for the principal.

The regulations reinforce that starting point. Title 19 NYCRR section 175.10 says a broker must never offer property for sale or lease without the owner's authorization, and section 175.11 requires the owner's consent before a sign is placed on the property. If a broker prepares an instrument concerning the broker's employment and a party signs it, section 175.12 requires the broker to deliver a copy to the signing party immediately.

Implied agency by words and conduct

New York courts state that agency may be established by conduct as well as by a written or oral contract. Implied agency arises when the parties' words, conduct and surrounding circumstances show the required consent and control even though they did not clearly state every term.

Consider a buyer who repeatedly asks a licensee to select properties, advise on price and negotiate solely for the buyer. The licensee repeatedly accepts those instructions and presents herself as advancing the buyer's interests. Those facts can raise an implied-agency question even if no one used the phrase “buyer agency.”

This is why licensees should identify the relationship early, use the required disclosure and document the actual agreement. Casual help can become legally significant when the conduct communicates representation.

Friendly assistance is not automatically agency

Opening a door, providing public facts or transmitting a document does not always mean the licensee has agreed to represent that consumer. The full relationship matters.

Ask:

• Did the consumer authorize the licensee to act for that consumer?
• Did the licensee accept that role?
• Was the licensee subject to that consumer's direction within an agreed scope?
• Did the licensee advise or negotiate as that consumer's advocate?
• What did the brokerage's words, documents and conduct communicate?

One isolated courtesy is weaker evidence than a continuing pattern of advice, direction and advocacy.

Ratification after an unauthorized act

Ratification concerns an act taken without actual authority at the time. A principal may later adopt the act and treat it as authorized. Knowing acceptance of the act or its benefits can be important evidence.

For exam analysis, look for four ideas:

1. the person purported to act for the principal
2. the act was initially outside actual authority
3. the principal learned the material facts
4. the principal then approved the act or accepted it in a manner consistent with approval

Silence is not automatically ratification. Knowledge and conduct matter. A person cannot fairly be said to adopt an act while unaware of the material circumstances.

Ratification also does not expand a real estate salesperson's license. A client cannot authorize a salesperson to operate independently of the sponsoring broker or perform conduct prohibited by license law.

Apparent authority is related but different

Apparent authority protects a third party who reasonably relies on words or conduct traceable to the principal that make an agent appear authorized. The supposed agent cannot manufacture apparent authority through the agent's statements alone.

This differs from the internal consent that creates actual agency. A principal may be bound to a third party by apparent authority even though the agent violated private instructions. Conversely, a person may be an actual agent yet lack authority for the particular act in dispute.

For this article, remember the distinction:

• actual agency asks what the principal and agent agreed, expressly or by conduct
• apparent authority asks what the principal communicated to a reasonable third party
• ratification asks whether the principal later adopted an initially unauthorized act

The next authority article examines those categories in depth.

The section 443 form does not create the relationship

The New York residential agency-disclosure form says, in capital letters, “THIS IS NOT A CONTRACT.” Its purpose is to tell consumers the nature of the licensee's agency role and the rights and obligations that role creates.

The form is evidence that information was disclosed and received. It is not the listing agreement, buyer-representation agreement or compensation agreement.

This gives four different questions:

Do not answer “agency was created because the consumer signed the disclosure” unless other facts establish consent to representation.

Disclosure timing still matters

For residential real property covered by section 443:

• a listing agent gives the form to the seller or landlord before entering the listing agreement
• a buyer's or tenant's agent gives it to that client before entering an agreement to act as the client's agent
• a seller's or landlord's agent gives it to the buyer or tenant at first substantive contact
• a buyer's or tenant's agent gives it to the seller, landlord or listing side at first substantive contact

The statute requires a copy for the signer and at least three years of retention. If a person refuses to sign the acknowledgment, the agent makes the sworn or affirmed written declaration required by the statute and retains it for at least three years.

A late or missing disclosure creates a compliance problem. It does not automatically rewrite the common-law facts because section 443 expressly says it does not limit or alter common-law agency.

Written informed consent is essential for dual agency

A broker may not represent both sides in the same transaction merely because the parties know the same brokerage is involved. Section 443 requires informed consent in writing for dual agency in covered residential transactions.

Advance informed consent can be indicated on the statutory form. The agent must still explain the possible effects, including the loss of undivided loyalty. Designated sales agents also require the written informed-consent structure and identification of the agents when applicable.

Dual agency is therefore not an accidental implied relationship that a licensee should allow conduct to create. The written-consent requirement is a specific safeguard.

The broker is the central contracting and supervisory party

The Department's salesperson FAQ states that a salesperson works for and is supervised by the representative broker and acts as the representative broker's agent. Listings negotiated by a salesperson are accepted by the representative broker.

This matters when a consumer says, “I hired that salesperson.” In the ordinary brokerage structure, the agency agreement is with the brokerage, and the affiliated salesperson performs under the broker's supervision.

The salesperson cannot take the client's listing file as personal property when changing firms. Title 19 NYCRR section 175.14 requires a salesperson whose broker association ends to turn over all listing information obtained during that association to the broker.

How agency ends by agreement or act

Mutual agreement

The principal and agent can agree to end the relationship. The termination document should identify the effective date and deal with open files, marketing, property access, funds, records, confidentiality and any surviving compensation clause.

Mutual termination of agency does not necessarily mean each party gives up every contractual claim. Read the actual release.

Revocation by the principal

A principal can communicate that the agent's authority is revoked. Once effective, the agent should stop acting under that authority.

Revocation of authority and breach of contract are separate questions. A principal may have power to end the agency but still face consequences under an enforceable agreement, such as a commission or protection clause. Do not turn “can revoke authority” into “can cancel every obligation without consequence.”

Renunciation by the agent

An agent can communicate that the agent will no longer act. The agent must handle the ending consistently with fiduciary, contractual, licensing and record duties. Abandoning a client at a critical point without proper communication can create a different legal problem even though the agency will not continue forever.

Expiration of the agreed term

A fixed-term agreement ends when its stated term expires unless the parties make a valid new agreement.

New York regulation 19 NYCRR section 175.15 prohibits a broker from being party to an exclusive listing contract that automatically continues beyond its fixed termination date. A new agreement requires an actual new choice, not a hidden automatic extension.

Completion of the authorized purpose

An agency created for one particular accomplishment can end when that task is finished. The exact endpoint depends on the assignment.

New York courts look at what the broker was hired to do. A broker engaged only to find a purchaser may complete that role at a different point from a broker retained through closing or for ongoing property management. Do not memorize “contract signing always ends agency” as a universal rule. Read the scope.

Operation of law

An agency may end through a legal event rather than a voluntary notice. Common examples discussed in agency law include death or incapacity of a necessary party, destruction of the subject matter, illegality or another event that makes the authorized purpose impossible.

The result can depend on the type of authority and governing document. A durable power of attorney, for example, follows its own statutory rules and should not be treated as an ordinary brokerage agreement. For exam questions, use the facts and identify whether the event makes continued performance legally or practically impossible.

What survives termination?

Termination stops future action under the ended authority. It does not necessarily erase the past.

Accounting and property return

Money, keys, documents and other property belonging to the principal must still be handled and accounted for. Title 19 NYCRR section 175.2 requires a broker within a reasonable time to render an account and remit client money collected and unexpended for the client's account.

Confidentiality

Ending representation does not give a former agent permission to use confidential information against the former client. The precise obligation depends on law and agreement, but exam questions should not assume all confidence becomes public on expiration.

Records

Section 443 acknowledgments and refusal declarations remain subject to the statutory three-year retention rule. Other transaction and brokerage records may have separate retention requirements.

Compensation and protection clauses

A listing or representation agreement may address compensation earned before termination or a later transaction involving a person introduced during the term. Whether payment is due depends on the agreement, performance, procuring-cause rules and any breach.

Avoid assuming either extreme:

• termination always destroys a commission claim
• termination always creates a commission

The contract and facts decide the issue.

Claims for an earlier breach

Termination does not erase a fiduciary breach, misrepresentation or contract breach that already occurred. A broker's breach of loyalty can affect compensation even when the relationship later ends.

Ending a salesperson's brokerage association is a different event

A salesperson's association with the sponsoring broker is a licensing relationship. The client's listing or representation agreement is ordinarily a brokerage relationship.

When a salesperson leaves:

1. the existing principal broker completes the Department termination process
2. the salesperson stops performing licensed activity under that broker
3. all listing information is returned to that broker
4. a new principal broker must complete a new association before the salesperson acts under the new firm

The salesperson cannot simply move the former brokerage's client relationship to the new firm. The client and broker must address any termination or new agreement lawfully and directly.

A reliable exam method

Use this sequence for every creation-or-termination problem.

Step 1: identify the alleged principal

Who supposedly authorized representation?

Step 2: identify the alleged agent

Is the relationship with the broker, an affiliated salesperson, a broker's agent or another person?

Step 3: find consent and control

Look for a written agreement, oral instructions or a pattern of accepted conduct.

Step 4: define the scope

Was the agent engaged to market, locate, negotiate, manage, sign or complete a specific transaction?

Step 5: separate disclosure from contract

A section 443 acknowledgment explains the role. It is not itself the representation contract.

Step 6: find the ending event

Look for expiration, completion, mutual agreement, revocation, renunciation or operation of law.

Step 7: identify surviving duties or rights

Check confidentiality, accounting, records, compensation, protection clauses and prior breaches.

Worked exam scenarios

Scenario 1: disclosure without representation agreement

A listing agent gives an unrepresented buyer the section 443 form. The buyer signs the acknowledgment.

The signature confirms receipt of the disclosure. It does not turn the listing agent into the buyer's agent. The form itself says it is not a contract.

Scenario 2: implied buyer agency

A broker repeatedly accepts a buyer's private instructions, recommends negotiation strategy solely for the buyer and tells others that the brokerage represents the buyer. No clear written representation agreement has been found.

The words and conduct can support an implied-agency analysis. Examine consent, control and the entire course of dealing.

Scenario 3: unauthorized price change

A salesperson lowers a listing price without authority. After learning every material fact, the seller confirms the new price in writing and proceeds on that basis.

The later informed approval may ratify the act. It does not excuse the salesperson from broker supervision or other license-law duties.

Scenario 4: fixed date passes

An exclusive listing states a fixed termination date and says it will renew automatically unless the seller cancels.

New York regulation prohibits automatic continuation of an exclusive listing beyond the fixed termination date. The broker should not treat the prohibited clause as a new term.

Scenario 5: task completed

A broker was retained only to find a purchaser. The broker produces the purchaser and the parties enter the transaction contemplated by the limited assignment.

The agency may end upon completion of that agreed purpose. Review the actual scope before deciding the endpoint.

Scenario 6: seller fires broker during an exclusive term

The seller clearly revokes the broker's authority before the agreement's fixed end date.

The broker must stop acting as authorized agent once the revocation is effective. A separate contract or commission dispute may remain. The power to end authority is not the same as a right to avoid every contractual consequence.

Scenario 7: salesperson changes firms

A salesperson joins a new brokerage and tells a seller that the listing came along automatically.

That is incorrect. The salesperson must return the listing information to the former broker, and the client's agreement with the brokerage must be handled separately.

Common misconceptions

“A signed disclosure creates agency”

No. The section 443 form says it is not a contract.

“Agency must always be written”

New York courts recognize agency established by written agreement, oral agreement or conduct. Specific transactions and consent rules can still require writing.

“Whoever pays the broker is the principal”

Not necessarily. Representation is determined by the relationship, not solely by the source of compensation.

“The agent decides the scope”

No. Authority comes from the principal, the agreement and the law. An agent cannot enlarge it through a personal claim of authority.

“Revocation erases the contract”

No. It ends authority when effective, but surviving contract issues may remain.

“Every agency ends at closing”

Not as a universal rule. The endpoint depends on the agreed task, term and surrounding facts.

“A salesperson owns the listing”

No. The salesperson acts through the sponsoring broker and must return listing information when the association ends.

Frequently asked questions

How is a real estate agency relationship created in New York?

It is created when a principal consents that an agent will act on the principal's behalf and subject to the principal's control, and the agent consents. The relationship can be shown by a written agreement, an oral agreement or conduct, subject to any rule requiring a writing for the particular arrangement.

Does signing the New York agency disclosure make someone a client?

No. The statutory form says it is not a contract. It explains the licensee's role and acknowledges receipt of that explanation.

Can agency be implied without a written buyer agreement?

It can be inferred from words and conduct when the facts show consent, action on the person's behalf and control. A clear written agreement is safer and may be required by brokerage policy or another applicable rule.

What is ratification?

Ratification is a principal's later adoption of an act initially taken without actual authority. Knowledge of the material facts and conduct showing approval are central.

How does an agency relationship terminate?

It may end by mutual agreement, revocation, renunciation, expiration, completion of its purpose or operation of law. The specific agreement and facts control.

Can a seller terminate a listing before its end date?

A seller can revoke the broker's authority, but ending authority may still create contractual or compensation consequences. Review the agreement and obtain legal advice for an actual dispute.

Can an exclusive listing renew automatically?

New York regulation prohibits an exclusive listing contract from automatically continuing beyond its fixed termination date.

Does agency end when a salesperson leaves the brokerage?

The salesperson's association with the broker ends, but that is not automatically the same as terminating the client's agreement with the brokerage.

Do fiduciary duties disappear after termination?

Future authority ends, but obligations involving confidential information, client money, records and earlier conduct can survive. The agreement and applicable law determine the details.

What to study next

Review agent, principal, client and customer to identify the represented party. Then study actual, apparent and unauthorized authority and use the Law of Agency study guide for duties, disclosures, dual agency and exam practice.
