Client Duties Versus Customer Duties

The easiest way to solve an exam question is to identify whom the agent represents before judging the conduct. The same licensee may owe loyalty and confidentiality to one side while owing honesty, care and specific disclosures to the other.

Client versus customer at a glance

The client receives advocacy. The customer receives fair dealing, not advocacy. That sentence resolves many agency questions.

Official source map

The New York State Department of State's 77-hour salesperson curriculum expressly covers clients and customers, fiduciary duties, agency disclosure, informed consent, confidentiality, misrepresentation and fair housing.

Real Property Law section 443 supplies the clearest residential comparison. Its statutory disclosure forms list the fiduciary duties owed to seller, buyer, landlord and tenant clients. The forms also describe the duties an agent should observe when dealing with the unrepresented party on the other side.

Section 443 applies to its defined residential transactions, including improved one-to-four-family dwellings and condominium or cooperative apartments. It does not replace common-law agency rules, and it does not turn every person who speaks with a licensee into a client.

The March 2026 Department of State license-law compilation adds regulations concerning disclosure of the party represented, compensation, owner authorization, broker supervision and other conduct. Real Property Law section 441-c authorizes discipline for fraud, misleading advertising, untrustworthiness, incompetency and other listed violations. These sources were checked on August 27, 2026.

Who is the client?

The client is the principal whom the broker has agreed to represent. Depending on the transaction, the client may be the seller, buyer, landlord or tenant.

Examples:

• A homeowner who signs a listing agreement with a broker is the listing broker's seller client.
• A buyer who engages a broker to negotiate for the buyer is the buyer client.
• A landlord who lists an apartment for rent is the landlord client of the listing broker.
• A tenant who engages a broker to find and negotiate a rental may be the tenant client.

A New York salesperson does not independently create a separate brokerage business. The Department of State explains that a salesperson works for and under the supervision of the representative broker and acts as that broker's agent. Exam questions may speak casually about “the salesperson's client,” but the brokerage relationship and supervising broker remain important.

Who is the customer?

In the usual exam use of the word, a customer is a consumer who deals with the licensee but is not represented by that licensee. The customer may be represented by another agent or may be unrepresented.

If a seller's agent meets an unrepresented buyer, the seller remains the client and the buyer is the customer of that agent. If a buyer's agent presents an offer to an unrepresented seller, the buyer remains the client and the seller is the customer of that agent.

Contact alone does not create representation. Showing a property, providing a factual listing sheet or presenting an offer does not necessarily make the recipient a client. The agency relationship depends on the actual agreement, conduct, authority and applicable law.

The six duties owed to a client

New York's residential agency-disclosure forms identify six fiduciary duties: reasonable care, undivided loyalty, confidentiality, full disclosure, obedience and a duty to account.

Reasonable care

The agent must perform the authorized work with appropriate skill, diligence and attention. A careful agent verifies information, communicates accurately, handles documents responsibly and recognizes when a lawyer, inspector, appraiser, lender or tax professional should answer a question.

Undivided loyalty

The agent puts the client's lawful interests ahead of a conflicting personal interest. Loyalty prohibits secret profits, undisclosed divided loyalties and favoring the agent's compensation over the client's objective.

Confidentiality

The agent protects confidential client information unless disclosure is authorized or required by law. A buyer's maximum price, a seller's minimum acceptable price and private negotiating strategy are common examples.

Confidentiality does not permit a lie. The agent can decline to reveal protected information without inventing facts or concealing something that lawfully must be disclosed.

Full disclosure

The agent tells the client material facts and conflicts that could affect the client's decisions. An ownership interest, divided loyalty, extra compensation or known issue relevant to the agency may require disclosure.

Obedience

The agent follows lawful client instructions within the agent's authority. The agent must refuse an instruction to discriminate, misrepresent a fact, conceal a legally required disclosure or mishandle money.

Duty to account

The agent safeguards and reports money, documents, keys and other property entrusted through the agency. The duty includes accurate records and proper handling of client funds under the applicable rules.

What a seller's or landlord's agent owes the customer

A seller's agent represents the seller, not the buyer. A landlord's agent represents the landlord, not the tenant. The agent should not negotiate against the client or give the customer advice designed to defeat the client's position.

However, section 443's forms state that, in dealings with the buyer or tenant, the seller's or landlord's agent should:

• exercise reasonable skill and care in performing the agent's duties
• deal honestly, fairly and in good faith
• disclose known facts materially affecting the property's value or desirability, except as otherwise provided by law

This is why “I represent the seller” is not a defense to a false statement about the roof, zoning, lawful occupancy or another material fact. Representation explains whose interests the agent advances. It does not authorize deception.

The phrase “except as otherwise provided by law” also matters. New York has specific rules for subjects such as stigmatized property. A salesperson should apply the governing law and broker guidance rather than assume that every fact about a property or prior occupant must be volunteered.

What a buyer's or tenant's agent owes the customer

A buyer's agent represents the buyer, not the seller. A tenant's agent represents the tenant, not the landlord. That agent should not reveal the client's confidential bargaining position merely to help the other side.

When dealing with the seller, section 443 says a buyer's agent should exercise reasonable skill and care, deal honestly, fairly and in good faith, and disclose known facts materially affecting the buyer's ability or willingness to perform that are not inconsistent with the agent's fiduciary duties to the buyer.

The landlord-tenant form contains the corresponding principle for a tenant's agent dealing with the landlord. It refers to facts about the prospective tenant's ability or willingness to perform, limited by the fiduciary duties owed to the tenant.

The qualification is essential. A buyer's agent should not falsely state that financing is final when it is not. The agent also should not volunteer the buyer's confidential maximum price or private motivation when no law or authorization requires it.

Advocacy and assistance are not the same

An agent can provide limited factual assistance to a customer without representing that person. The line is crossed when the agent begins advising the customer as though the agent were loyal to that customer's interests.

For example, a seller's agent may:

• provide accurate property information
• explain the mechanics for submitting an offer
• transmit the customer's offer promptly through the proper channel
• identify that the agent represents the seller
• suggest that the unrepresented buyer obtain legal, inspection or other professional advice

The seller's agent should not tell the buyer what price would best protect the buyer, reveal the seller's confidential bottom line or claim to negotiate on the buyer's behalf.

Likewise, a buyer's agent may explain the buyer's offer and transaction process to an unrepresented seller. The agent should not tell that seller what counteroffer best serves the seller or disclose the buyer's confidential ceiling.

Compensation does not decide who is represented

Payment and agency are separate questions. A person may fund or contribute to compensation without becoming the agent's client, and an agent may represent a client whose compensation is paid through another permitted arrangement.

For an exam question, avoid inferring representation from who writes the check. Look for the agency agreement, disclosure, conduct and authority.

Title 19 NYCRR section 175.7 requires the broker to make clear for which party the broker is acting. It also restricts compensation from more than one party unless the broker's client has full knowledge and gives consent. That compensation consent does not replace any separate agency or dual-agency consent requirement.

The agency disclosure form explains the relationship

Section 443's form prominently states that it is not a contract. Its purpose is to explain the nature of the agency relationship and the rights and obligations it creates. Signing an acknowledgment generally documents receipt of that disclosure. It should not be confused with an agreement that hires the broker.

For covered residential transactions, timing matters:

• The listing agent gives the form to the seller or landlord before entering the listing agreement.
• 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 agent's own client before entering the agency agreement.
• A buyer's or tenant's agent gives it to the other side at first substantive contact with that side.

The agent provides a copy of the signed acknowledgment and retains a copy for at least three years. If a party refuses to sign, the statute calls for a written declaration of the facts under oath or affirmation and retention for at least three years.

A customer does not silently become a client

An unrepresented customer who wants advocacy should discuss representation before relying on the licensee for negotiation advice. The broker must evaluate conflicts, existing agreements and the form of agency permitted in the transaction.

A licensee should not drift between roles. Saying “I represent the seller” and then privately advising the buyer how to defeat the seller's position creates confusion and a possible agency or loyalty problem. Clear role disclosure, consistent conduct and broker supervision protect everyone involved.

An implied agency issue may arise from conduct even when no written hiring agreement appears. That does not make informal role switching a good practice. Section 443 expressly preserves common-law agency principles.

Dual agency changes the comparison

Dual agency exists when the broker represents both sides in the same transaction. In a covered residential transaction, the buyer and seller, or tenant and landlord, must give informed consent in writing.

A dual agent cannot provide both principals the full range of fiduciary duties. New York's form explains that the parties give up their right to undivided loyalty. Advance consent on a form does not remove the need to understand the actual conflict when it arises.

Dual agency with designated sales agents also requires informed written consent. Different designated agents advocate for the respective parties under the supervision of the dual-agent broker, but the statutory form warns that the designated agents still cannot provide the full range of fiduciary duties or undivided loyalty.

Do not solve a dual-agency question by labeling one principal a customer. Both are clients of the dual-agent broker, but their consent permits a limited form of divided representation.

Broker's agent is a separate relationship

A broker's agent cooperates with or is engaged by a listing agent, buyer's agent or tenant's agent from another firm to assist that engaging agent. Section 443 says the broker's agent has no direct relationship with the ultimate seller, buyer, landlord or tenant. The ultimate party cannot directly instruct the broker's agent.

The engaging listing, buyer's or tenant's agent gives direction and bears the vicarious liability described by the statute. This is different from a customer relationship and different from designated agency within one brokerage.

Fair housing duties apply to clients and customers

No agency label authorizes discrimination. New York licensees must follow federal, state and applicable local fair housing requirements when advertising, qualifying, showing, negotiating and delivering services.

An agent must not obey a client's unlawful preference, such as a direction to exclude people because of a protected characteristic. The agent also must not provide inferior information or service to someone merely because that person is a customer rather than a client.

The Department of State may discipline a licensee for an Article 15 Human Rights Law violation committed in the licensee's professional capacity. Fair housing is therefore both a public-law obligation and a licensing issue.

Eight worked scenarios

Scenario 1: the buyer asks the listing agent what to offer

The listing agent represents the seller. The agent may explain the offer process and provide accurate facts, but should not advise the buyer on the price that best protects the buyer. The buyer is a customer, not that agent's client.

Scenario 2: the buyer reveals a maximum price

An unrepresented buyer tells the seller's agent, “I can go as high as $800,000.” The buyer should not assume that statement is protected by a fiduciary confidentiality duty from the seller's agent. The agent owes loyalty and disclosure to the seller client, subject to law and the actual circumstances.

The practical lesson is to identify representation before sharing negotiating information.

Scenario 3: the seller reveals a minimum price

The seller tells the listing agent that $700,000 is the lowest acceptable price. A buyer asks whether the seller would take $700,000.

The seller's agent protects the client's confidential bargaining position and does not lie. A proper response can decline to reveal confidential information while inviting an offer.

Scenario 4: known material property information

A seller's agent knows of a recurring basement-water problem that materially affects the property's value or desirability. The agent cannot treat the buyer's customer status as permission to mislead or ignore the disclosure rule. The agent must apply New York law, the facts and broker guidance.

Scenario 5: uncertain financing

A buyer's agent knows the buyer has only a preliminary lender conversation but tells the seller that the loan has final approval.

That is not protected advocacy. It is a misleading statement about the buyer's ability to perform. The agent can accurately describe the verified financing stage without revealing unrelated confidential information.

Scenario 6: customer requests advocacy

An unrepresented buyer asks the seller's agent to recommend the lowest price and contingencies most favorable to the buyer.

The agent should restate the seller representation and avoid acting as the buyer's advocate. The buyer can seek independent representation or professional advice.

Scenario 7: unlawful client instruction

A landlord tells the listing agent to discourage applicants with children.

The instruction is unlawful. The agent must refuse and follow fair housing law. Loyalty and obedience do not excuse discrimination.

Scenario 8: both sides ask for representation

A listing broker's buyer customer asks the same brokerage for representation in the transaction.

The broker must address the conflict and obtain the informed written consents required for dual agency or dual agency with designated sales agents if that arrangement is used. The broker cannot silently promise undivided loyalty to both sides.

A five-step exam method

1. Identify the transaction parties.
2. Identify whom the broker represents.
3. Label the represented party the client and the unrepresented party the customer for that agent.
4. Apply fiduciary duties to the client and fair-dealing duties to the customer.
5. Check for disclosure, dual agency, fair housing, misrepresentation or compensation rules that also apply.

When two answer choices both sound ethical, ask which one respects the existing client relationship without misleading the customer.

Common misconceptions

“A customer is owed no duties”

False. The customer is not owed the agent's undivided loyalty, but is still owed the care, honesty, fairness, good faith and disclosures applicable to the dealing.

“The person who pays the agent is always the client”

False. Payment does not by itself create agency. Determine whom the broker agreed and is authorized to represent.

“A disclosure form hires the agent”

False. Section 443's form states that it is not a contract. It explains and acknowledges the agency relationship.

“A listing agent can advise an unrepresented buyer because nobody else represents the buyer”

Not as the buyer's advocate while owing loyalty to the seller. The agent may give factual and procedural assistance while maintaining the disclosed role.

“Confidentiality lets an agent give a false answer”

False. The agent can protect a confidence without lying.

“Obedience requires following every client instruction”

False. Obedience applies only to lawful instructions within the agency.

“Dual agency makes one party a customer”

False. A dual agent represents both principals with informed written consent, but cannot give either the full range of fiduciary duties.

“The same rules apply only to sales”

False. Section 443 contains parallel forms for residential buyer-seller and landlord-tenant transactions.

Frequently asked questions

What is the difference between a client and a customer in New York real estate?

A client is represented by the agent and receives fiduciary duties. A customer is not represented by that agent but still receives reasonable skill and care, honest and fair treatment, good faith and legally required disclosures.

What duties does a New York real estate agent owe a client?

New York's residential agency form lists reasonable care, undivided loyalty, confidentiality, full disclosure, obedience and a duty to account.

Does a seller's agent owe duties to a buyer?

Yes. The seller's agent does not represent the buyer, but section 443's form calls for reasonable skill and care, honest, fair and good-faith dealing, and disclosure of known facts materially affecting property value or desirability, except as otherwise provided by law.

Does a buyer's agent have to disclose information to the seller?

The form calls for honest, fair and careful dealing and disclosure of known facts materially affecting the buyer's ability or willingness to perform, when disclosure is not inconsistent with the agent's fiduciary duties to the buyer.

Can a customer rely on the other side's agent for advice?

The customer can receive accurate factual and procedural information, but should not expect advocacy or advice designed to advance the customer's interests from an agent who represents the other side.

Is a signed agency-disclosure form a representation contract?

No. The statutory form expressly says it is not a contract. It discloses the role and documents receipt. A separate agreement or the parties' conduct may establish the agency.

Can one broker represent both buyer and seller?

Yes, through dual agency if both parties give informed consent in writing. The agent cannot then provide either party the full range of fiduciary duties or undivided loyalty.

Do fair housing laws protect customers as well as clients?

Yes. Fair housing duties apply to real estate services regardless of whether the consumer is the agent's client or customer.
