Agency is one of the most important concepts in Illinois real estate practice. It determines who a broker represents, what duties the broker owes to that client, what information must remain confidential, and what disclosures are required when working with other parties.
Illinois primarily uses a designated agency system. A consumer working with a licensee is generally treated as being represented by that licensee as a designated agent unless the sponsoring broker and consumer establish a different relationship in writing.
This guide explains Illinois real estate agency in practical terms for brokers, buyers, sellers, landlords, tenants, and individuals preparing for the Illinois broker examination.
Important Illinois agency concepts include:
Understanding these concepts helps brokers identify:
Who is represented, what duties are owed, and what information can or cannot be disclosed.
Under the Illinois Real Estate License Act, agency generally refers to a relationship in which a broker or licensee represents a consumer in a real property transaction with the consumer's consent.
Agency affects how the licensee must act throughout the transaction.
For example, an agent representing a client has responsibilities involving:
Agency is therefore much more than simply helping someone buy or sell a property.
Illinois primarily operates under a designated agency framework.
In designated agency, one or more specific licensees affiliated with a sponsoring broker are designated to represent a particular client.
For example:
A brokerage firm may have many brokers.
However, a particular seller may be represented by:
Broker A
while a buyer working with the same brokerage may be represented by:
Broker B
The agency relationship is based on the designated licensees representing each client rather than automatically treating every licensee in the brokerage as the client's agent.
Current Illinois law provides that a licensee is generally considered to be representing the consumer the licensee is working with as a:
Designated agent
unless the sponsoring broker and consumer have a written agreement establishing a different relationship.
This means brokers should not leave consumers uncertain about representation.
The agency relationship should be clearly established and properly documented.
A designated agent is a sponsored licensee who has been specifically identified to act as the legal agent of a client.
The designated agent represents that client's interests in the transaction.
For example:
Broker A may be designated as the seller's agent.
Broker B may be designated as the buyer's agent.
Even when both brokers work under the same sponsoring broker, each designated agent can represent a different client.
Current Illinois law requires a sponsoring broker entering into a brokerage relationship for activities such as:
to set forth the terms of that relationship in a:
Written brokerage agreement
The agreement identifies the relationship between the brokerage and the client and specifically designates the licensees who will act as the client's legal agents.
A brokerage agreement can address matters such as:
Brokers should use the brokerage's approved agreements and follow applicable Illinois requirements.
A brokerage agreement is not merely an administrative form.
It defines an important professional relationship.
Illinois requires a licensee acting as a designated agent to advise the consumer in writing of the agency relationship:
No later than beginning to work as a designated agent for the consumer.
The disclosure should identify:
The disclosure can be included within the brokerage agreement or provided through a separate document.
A copy must be provided to the consumer or client, and the sponsoring broker retains the applicable record.
Consumers should understand whether the broker:
This matters because representation affects:
A consumer should not have to guess whose interests the broker is representing.
The difference between a client and a customer is fundamental.
A consumer who is represented by the licensee through the applicable brokerage relationship.
A consumer who is not being represented by the licensee.
A broker still owes important duties to a customer, but those duties are different from the duties owed to a represented client.
Imagine a listing broker represents the seller.
The seller is the broker's:
Client
A buyer contacting the listing broker without establishing representation may be treated as:
A customer rather than the broker's client
The listing broker still needs to treat the buyer honestly and comply with applicable disclosure requirements.
However, the broker's agency duties remain with the seller client.
Illinois requires a licensee to disclose in writing to a customer that the licensee is not acting as the customer's agent.
The disclosure should be made at a time intended to prevent the customer from revealing confidential information to a broker who does not represent them.
In any event, the disclosure must occur no later than the preparation of an offer to:
This helps consumers understand the relationship before sharing sensitive negotiation information.
Suppose a buyer tells the seller's agent:
"I can actually pay $30,000 more than my offer, but please don't tell the seller."
If that broker represents the seller rather than the buyer, the buyer should not assume the broker owes them the same confidentiality duties that an agent would owe a client.
This is why agency status should be clear early in the transaction.
Consumers should understand who represents them before sharing sensitive negotiating information.
Illinois law establishes important duties for licensees representing clients.
A licensee should:
These duties form the foundation of the agency relationship.
The broker must perform the services promised under the brokerage agreement.
For example, depending on the agreement, this can involve activities such as:
The brokerage agreement defines the relationship, so brokers should understand its terms before acting.
Illinois law requires a licensee representing a client to act consistently with promoting the client's best interests rather than the broker's own interests or someone else's interests.
For example, a broker should not recommend a course of action merely because it produces:
The broker's advice and professional actions should remain consistent with the duties owed to the client.
An Illinois broker generally follows the client's specific directions when those directions are not contrary to:
This limitation is important.
A client cannot require a broker to participate in unlawful conduct.
For example, a seller cannot lawfully instruct a broker to discriminate against buyers based on a protected characteristic.
A licensee representing a client generally must timely present offers to and from the client unless the client has properly waived that duty.
This can apply when representing:
A broker should not ignore, hide, or delay an offer simply because the broker personally dislikes the terms.
The decision generally belongs to the client.
Agency does not mean the broker makes every decision for the client.
The broker may:
But major transaction decisions remain with the client.
For example, the seller decides whether to:
The broker helps the client make an informed decision.
Illinois law requires licensees representing clients to exercise:
Reasonable skill and care
in the performance of brokerage services.
This means brokers should perform their professional responsibilities carefully and competently.
Examples include:
A broker should know when to involve a managing broker, attorney, inspector, lender, accountant, or another qualified professional.
A licensee representing a client must protect the client's confidential information.
Illinois law defines confidential information to include certain information obtained from a client that:
Confidentiality can affect many aspects of negotiation.
Depending on the circumstances, confidential information can include matters such as:
Brokers should not casually disclose information that could damage their client's negotiating position.
Not every piece of information becomes confidential merely because a client would prefer that it remain hidden.
For example, Illinois law does not treat applicable material information about the physical condition of property as confidential information simply because disclosure could affect negotiations.
A broker should understand the difference between:
Negotiating confidentiality
and:
Information that must be disclosed under applicable law
Under Illinois law, disclosure can be permitted or required in circumstances such as when:
Brokers should not independently decide that confidential information is safe to disclose without considering the applicable agency and legal rules.
The broker's confidentiality responsibilities do not necessarily disappear when the brokerage agreement ends.
Illinois law provides that after termination, expiration, or completion of the brokerage agreement, certain duties continue.
These include:
A former client does not automatically lose all confidentiality protection simply because the agreement has ended.
A broker still has responsibilities to consumers who are not clients.
Illinois law requires licensees to:
A seller's agent also has specific responsibilities regarding certain known latent material adverse facts affecting the physical condition of the property.
A broker should never interpret "customer" to mean:
"Someone I owe no duties to."
A seller's agent must timely disclose to prospective buyer customers certain:
Latent material adverse facts concerning the physical condition of the property
when:
This is an important distinction between:
Confidential negotiation information
and:
Applicable material property information
Representing a client does not give a broker permission to lie for that client.
A broker should not:
The duty to promote the client's interests operates within the law.
A buyer's designated agent represents the buyer in the applicable transaction.
The relationship can involve duties such as:
The specific services should be addressed through the written brokerage agreement.
A seller's designated agent represents the seller.
Services may include:
The broker should follow the brokerage agreement and applicable Illinois requirements.
Agency is not limited to property sales.
Illinois agency law also applies to:
A broker representing a landlord has duties to the landlord client.
A broker representing a tenant has duties to the tenant client.
The parties should understand who is represented before sensitive information is exchanged.
Dual agency occurs when an individual licensee represents:
or:
in the same transaction.
Because the two clients may have competing interests, dual agency creates an inherent conflict that requires special treatment under Illinois law.
An Illinois licensee may act as a dual agent only with the:
Informed written consent of all clients
A broker should not simply decide midway through a transaction to represent both sides without proper disclosure and consent.
Clients need to understand that dual representation affects the type of advice and information the broker can provide.
Consider a sale.
The highest acceptable price and favorable terms.
The lowest acceptable price and favorable terms.
If the same individual licensee represents both, the broker cannot fully advocate one side's negotiating position against the other while also protecting both clients' confidential information.
That is why Illinois requires informed written consent.
Illinois's statutory dual-agency disclosure identifies services a dual agent can continue providing.
For example, a dual agent can generally:
Dual agency does not mean the broker stops providing brokerage services.
However, the broker's ability to advise either party about certain negotiating positions becomes limited.
Without the applicable client's permission, a dual agent cannot disclose confidential negotiating information about one client to the other.
For example, the dual agent should not reveal that:
unless the applicable disclosure is permitted or required.
Protecting both clients' confidential information is essential.
Illinois law also requires confirmation of the clients' prior dual-agency consent in the specific transaction.
This confirmation should generally be obtained when the clients are executing an:
in the transaction involving dual agency.
If the confirmation appears within another document, Illinois law provides specific requirements for acknowledging that provision.
Dual agency requires consent.
If a client does not want the same licensee to represent both parties, the client does not have to agree to dual representation.
Illinois law allows a licensee, in applicable circumstances, to withdraw from representing one client who has not consented to the disclosed dual agency while continuing to represent the other client.
The brokerage should follow the applicable legal and company procedures.
Illinois law specifically prohibits a licensee from serving as a dual agent in a transaction when:
or
Personal ownership creates a conflict that prevents the licensee from acting as the dual agent.
This is an important Illinois concept.
Suppose:
That does not automatically mean every person involved is operating under dual agency.
Illinois designated agency focuses on the specific designated agents representing each client.
If different licensees are properly designated to different clients, the sponsoring broker is not automatically considered to be representing both parties merely because both agents are affiliated with the same brokerage.
When different designated agents within the same sponsoring brokerage represent different clients, the sponsoring broker has responsibilities involving protection of confidential client information.
A sponsoring broker must take ordinary and necessary care to prevent improper disclosure of confidential information.
Brokerages should therefore have procedures for:
Confidential information should not casually move from one designated agent to another.
Yes.
Illinois law permits a designated agent to share confidential information with the sponsoring broker or specified persons within the brokerage when doing so is necessary to seek:
for the benefit of the client regarding a possible transaction.
The sponsoring broker or other authorized person must still protect that information unless disclosure is otherwise permitted or required.
Illinois law specifically states that:
Compensation does not determine the agency relationship.
This is an important exam and practice concept.
Who pays a broker does not automatically determine who that broker represents.
Agency is determined by the actual representation relationship—not simply by the source of compensation.
Suppose a buyer's broker receives compensation connected with a transaction involving the seller or another brokerage.
That payment alone does not automatically transform the buyer's broker into the seller's agent.
The key question remains:
Who does the licensee represent under the applicable agency and brokerage agreements?
Do not identify agency solely by following the money.
Current Illinois agency-disclosure law also requires the licensee representing the consumer to discuss the sponsoring broker's compensation policy.
This includes applicable matters involving:
Consumers should understand how the brokerage expects to be compensated as part of the representation relationship.
An Illinois licensee can sometimes represent more than one client who wants to make an offer on the same property.
This can create an important agency issue.
Current Illinois law requires written disclosure to all affected clients when the licensee is preparing or making:
Contemporaneous offers or contracts to purchase or lease the same property
If a client requests referral to another designated agent, the applicable referral requirement also applies.
Suppose Broker A represents:
and both want to offer on the same house.
The broker now represents two clients whose immediate interests may compete.
Illinois law does not automatically prohibit the broker from working with both, but the situation requires the appropriate written disclosure.
Clients need to understand the potential conflict.
A buyer's agent may represent several buyers.
A seller's agent may work with several properties or consumers.
Illinois law recognizes that ordinary real estate practice can involve:
The existence of another client does not automatically mean the broker has breached the agency relationship.
The broker still needs to satisfy confidentiality, disclosure, and other duties.
An agent's obligation to protect confidential client information does not eliminate applicable duties concerning material property information.
Brokers should distinguish among:
When unsure, consult brokerage procedures and the applicable Illinois disclosure rules.
Illinois law limits liability for failure to disclose certain facts that do not affect the physical condition of the property.
Examples identified by statute include certain:
Brokers should not confuse these issues with known physical material defects.
Promoting a client's best interests does not permit a broker to violate fair housing or civil rights laws.
Illinois law specifically requires licensees representing clients to comply with applicable statutes and regulations, including:
A seller, landlord, buyer, or tenant cannot use an agency relationship to require unlawful discrimination.
A broker can explain real estate concepts and provide brokerage services within the broker's professional role.
However, agency does not make the broker the client's:
When a client needs specialized advice, recommend that the client consult an appropriately qualified professional.
Knowing the limits of the broker's role is part of exercising reasonable skill and care.
An agency relationship can end through circumstances such as:
After termination, most active representation duties end unless the parties agreed otherwise.
However, certain responsibilities continue.
After a brokerage agreement ends, Illinois law preserves important duties involving:
The brokerage must account for applicable money and property relating to the transaction.
Confidential information received during the brokerage relationship remains protected.
Termination does not create permission to reveal a former client's negotiating information.
Agency relationships create important documentation.
Records can include:
Follow your sponsoring brokerage's recordkeeping procedures and current Illinois requirements.
Good documentation helps demonstrate that the parties understood the relationship.
Before proceeding, identify:
Buyer, seller, landlord, or tenant?
Are they a client or a customer?
Which broker has been assigned to represent the client?
Is the relationship properly documented?
What information must be protected?
Who represents the other side?
Clear answers early can prevent agency confusion later.
Before telling another party something about your client, ask:
If you are uncertain, consult your managing broker before communicating the information.
When representing a seller:
When representing a buyer:
Before acting as a dual agent:
When working with someone you do not represent:
Illinois uses designated agency.
Agency status should be clear before sensitive information is exchanged.
Do not create confusion about whom you represent.
Protect confidential client information.
Applicable physical material facts are not automatically protected as client confidentiality.
Illinois specifically states that it does not.
Dual agency requires informed written consent.
Prior consent does not eliminate the applicable confirmation requirement.
Multiple clients competing for the same property can trigger additional disclosure requirements.
Agency is also a significant part of Illinois broker exam preparation.
Important concepts include:
The national broker content outline also gives agency substantial weight.
Students should understand these concepts through scenarios rather than memorizing definitions only.
Suppose a broker represents a buyer.
The buyer privately tells the broker:
"I will pay up to $450,000, but I want to start with an offer of $420,000."
The seller asks the buyer's broker:
"What is the most your client will pay?"
The buyer's maximum negotiating position is the type of information the broker should recognize as potentially confidential.
The broker should not simply reveal it to help complete the transaction.
Understanding the reason behind the duty makes agency questions easier to answer.
Suppose a listing broker represents the seller.
An unrepresented buyer contacts that broker directly.
The buyer should understand that:
This is why Illinois requires written disclosure when the licensee is not acting as the customer's agent.
Suppose:
Broker A represents the seller.
Broker B represents the buyer.
Both are affiliated with the same sponsoring brokerage.
Because Illinois uses designated agency, the seller can be represented by Broker A while the buyer is separately represented by Broker B.
The brokers and sponsoring brokerage must still protect each client's confidential information.
This is different from one individual licensee personally representing both parties as a dual agent.
When an agency question becomes confusing, use this sequence:
Identify the Parties
↓
Identify Who the Broker Represents
↓
Determine Whether the Person Is a Client or Customer
↓
Identify the Duty Owed
↓
Check Confidentiality
↓
Check Required Disclosure
↓
Check for Dual Agency or Conflicts
This framework is useful both in professional practice and on the licensing examination.
The central question in agency is simple:
Who does this broker represent?
Once that is clear, many other duties become easier to understand.
Representation affects:
Brokers should establish representation clearly, document it properly, and continue reviewing agency obligations throughout their careers.
Agency is one of the subjects where classroom concepts quickly become real professional responsibilities.

Agency is a relationship in which a broker or licensee represents a consumer in a real property transaction with the consumer's consent. The agency relationship creates specific duties involving representation, confidentiality, offers, material information, and professional conduct.
Designated agency is a relationship in which one or more specific licensees affiliated with a sponsoring broker are designated to act as legal agents of a particular client.
Current Illinois law provides that licensees are generally considered to represent the consumers they are working with as designated agents unless the sponsoring broker and consumer have a written agreement establishing a different relationship.
Current Illinois law requires a sponsoring broker entering into a brokerage relationship for listing, buying, selling, exchanging, renting, or leasing real estate to set forth the terms of that relationship in a written brokerage agreement.
A client is represented by the licensee. A customer is a consumer who is not represented by that licensee. A broker still owes honesty and other applicable duties to customers, but the full agency duties owed to a client are different.
A licensee acting as a designated agent must provide the applicable written disclosure no later than beginning to work as a designated agent on behalf of the consumer.
Illinois requires written disclosure at a time intended to prevent the customer from disclosing confidential information, but no later than the preparation of an offer to purchase or lease real property.
Duties include performing the brokerage agreement, promoting the client's best interests, timely presenting offers, disclosing applicable material facts, accounting for money and property, following lawful client directions, exercising reasonable skill and care, protecting confidential information, and complying with applicable laws.
A licensee representing a client generally has a duty to timely present offers to and from the client unless that duty has been waived as permitted under the applicable rules.
Confidential information can include information made confidential by the client's written request or instruction, information concerning the client's negotiating position, or information whose disclosure could materially harm the client's negotiating position, subject to statutory exceptions.
Not entirely. Illinois law provides that the obligation to protect confidential information received during the brokerage relationship continues after termination, expiration, or completion of the agreement.
Illinois law does not treat material information about the physical condition of the property as confidential merely because a client would prefer it not to be disclosed. Applicable disclosure requirements still need to be followed.
Illinois licensees must treat customers honestly and must not knowingly or negligently provide false information. Seller's agents also have duties regarding certain actually known latent material adverse physical facts that a reasonably diligent inspection would not reveal.
Dual agency occurs when one individual licensee represents both buyer and seller, or both landlord and tenant, in the same transaction.
Illinois permits dual agency when the statutory requirements are satisfied, including informed written consent from all clients and the applicable transaction-specific confirmation.
Yes. Dual agency requires the informed written consent of all affected clients. A client is not required to agree to dual representation.
Not simply because the broker represents both parties. Confidential negotiating information about one client generally cannot be disclosed to the other without applicable permission or legal authority.
Dual agency does not eliminate applicable duties involving known material property information. Illinois's statutory dual-agency framework specifically recognizes disclosure of known latent material defects among services that can still be performed.
No. Illinois designated agency allows different affiliated licensees to be designated to separate clients. The sponsoring broker is not automatically treated as representing both parties merely because both designated agents work for the same brokerage.
No. Illinois law prohibits a licensee from serving as a dual agent when the licensee, or an entity in which the licensee has or will have an ownership interest, is a party to the transaction.
No. Illinois law expressly states that compensation does not determine the agency relationship.
Current Illinois agency-disclosure law requires a licensee representing a consumer to discuss the sponsoring broker's compensation policy, including applicable terms of compensation and amounts offered to cooperating brokers representing other parties.
It can occur, but Illinois law requires written disclosure to all affected clients when the licensee is preparing or making contemporaneous offers or contracts on the same property. A client requesting referral to another designated agent must also be handled according to the applicable requirement.
No broker should carry out an unlawful discriminatory instruction. Illinois agents must comply with fair housing and civil rights laws even while promoting a client's lawful interests.
Unless otherwise provided by an applicable written agreement, Illinois law preserves duties involving accounting for transaction-related money and property and protecting confidential information received during the brokerage relationship.
Yes. Agency is a significant part of broker examination preparation. Candidates should understand representation, designated agency, client and customer relationships, duties, confidentiality, disclosure, dual agency, and related transaction scenarios.
Use the current Illinois Real Estate License Act, IDFPR guidance, applicable administrative rules, brokerage policies, and professional legal guidance when needed. Agency requirements can have important legal consequences, so brokers should not rely on outdated forms or informal explanations.
