Illinois License Act study guide

Illinois Agency Relationships

Illinois generally treats the licensee working with a consumer as that consumer's designated agent unless a written agreement provides a different relationship. Identify whom each licensee represents, then apply the right client duties, customer protections and disclosure deadlines. Dual agency requires informed written consent from all clients and transaction-specific written confirmation.

Last reviewed: October 24, 2026

Who does an Illinois real estate agent represent?

Start with each individual licensee and each consumer. A brokerage logo, an open-house conversation or the commission source does not answer the whole relationship question. Under 15-10, designated agency is the starting relationship unless the sponsoring broker and consumer agree in writing to a different one.

Illinois agency terms and their practical meaning
Term	Meaning	What to check
Consumer	A person or entity seeking or receiving licensed activities.	This broad label alone does not tell you whether the person is represented.
Client	A person represented by a licensee.	Apply the client duties in 15-15 and identify that client's designated agent.
Customer	A consumer not represented by the particular licensee.	Someone can be your customer while being another licensee's client.
Designated agency	The sponsor names one or more affiliated licensees as the client's legal agents, excluding the firm's other licensees.	Different agents at one firm can represent opposing clients without either agent representing both sides.
Dual agency	A licensee represents both buyer and seller, or both landlord and tenant, in the same transaction.	Look at the designated agent's relationships. Shared sponsorship alone does not establish dual agency.

15-50(a) requires the sponsor to put listing or representation terms in a written brokerage agreement and name the designated agents. A no-agency notice and a brokerage agreement serve different purposes. The notice says whom a licensee does not represent; the agreement records a brokerage relationship and its terms.

Required writing does not erase an unwritten relationship

Under 15-50(a-5), a client may still seek enforcement of an oral agreement. Absence of writing is not the stated affirmative defense to an agreement's existence or whether licensed activity occurred, and courts retain legal and equitable remedies. This preserves client remedies; it does not excuse the broker's writing duty or automatically award a commission.

15-40 also says payment does not determine agency. If an agreed seller payment helps fund the buyer's broker, follow the buyer's designated relationship rather than relabeling that agent as the seller's representative.

When are Illinois agency disclosures due?

There is no single disclosure deadline for every relationship. Use 15-35 for designated and no-agency notice, 15-45 for dual consent and confirmation, and the contemporaneous-offer rule for competing clients.

Illinois agency disclosure timing and required action
Disclosure	Timing	Required detail
Designated-agency notice: 15-35(a)	In writing, no later than beginning to work as the consumer's designated agent.	Identify the relationship and name the designated agents. The notice may be in the brokerage agreement or separate; retain a copy and give the consumer or client a copy.
No-agency notice: 15-35(c)	In writing, early enough to prevent a customer revealing confidential information, and never later than preparing an offer to buy or lease.	Offer preparation is the latest boundary, not permission to invite sensitive disclosures beforehand.
Initial dual disclosure and consent: 15-45(a)-(b)	Present the form when entering the brokerage agreement if offering dual representation. Obtain informed written consent from all clients before acting as dual agent.	Presentation and signature are separate steps. A client may sign later, but before dual representation begins.
Transaction-specific dual confirmation: 15-45(c)	Written confirmation of the clients' prior consent is required; the statute says it should be obtained when they execute the offer or contract.	If included in another document, the client must sign that document and initial the dual-agency confirmation provision.
Contemporaneous offers: 15-15(b), 1450.830	When the same agent knows or has reason to know multiple clients' offers on the same parcel or unit will be considered together, give written notice to those clients.	Physical or electronic notice is allowed. Refer a client to another designated agent on request; do not disclose another client's confidential terms.

The representing licensee must also discuss the sponsor's compensation policy, terms and amounts offered to cooperating brokers representing other parties under 15-35(b).

Keep the brokerage-agreement clock separate

Under 1450.770(g)-(h), a seller or owner agreement comes before marketing or listing. A buyer or tenant agreement is due before engaging in, or as soon as reasonably practical after performing, licensed activities intended to assist the purchase or lease. That wording does not postpone the designated-agency notice deadline.

For a listing licensee becoming a dual agent, 1450.770(i)(2) is more specific: execute a buyer or tenant brokerage agreement and comply with 15-45 before performing licensed activities on that buyer's or tenant's behalf. For agreement contents, see Illinois brokerage agreements.

What duties does an Illinois agent owe a client?

15-15(a) requires the representing licensee to perform the brokerage agreement, promote the client's best interests, exercise reasonable skill and care, preserve confidential information and comply with applicable law, including fair housing and civil rights requirements.

Price and terms: seek the transaction stated in the agreement or otherwise acceptable to the client.
Offers: timely present all offers to and from the client, subject to the statutory waiver language and the exclusive-agreement minimum services below.
Material facts: disclose actually known material transaction facts unless protected as confidential information.
Money and property: account promptly for what was received in which the client has, may have or should have had an interest.
Instructions and conflicts: follow lawful specific directions and promote the client's interests over the licensee's or someone else's self-interest.

A seller's instruction to hide a known material physical defect is not an instruction to obey. The statutory confidentiality definition excludes material information about physical condition.

An exclusive agreement includes minimum services

15-75 requires accepting and presenting offers and counteroffers, helping develop, communicate, negotiate and present related offers and notices until a purchase or lease agreement is signed and all contingencies are satisfied or waived, and answering the client's questions about them. Under 1450.770(b)(2), omitting or waiving those minimum services makes the agreement non-exclusive. Do not turn the general offer-waiver phrase into an exclusive agreement with no minimum service obligation.

Showing alternative properties, showing a property to other prospects or preparing qualifying contemporaneous offers is not itself a breach under 15-15(b). Nor does 15-15(c) presume a breach merely because a buyer agent's compensation increases with price. Those provisions do not remove disclosure, confidentiality or best-interest duties.

What protection does an unrepresented customer receive?

Honesty remains required without representation. Under 15-25, licensees must treat customers honestly and must not negligently or knowingly give false information.

That section specifically requires a seller's agent to timely disclose to prospective buyer customers actually known latent material adverse physical facts that a reasonably diligent customer inspection would not reveal. Keep each part of that test. It is not permission to hide a concealed structural problem, and it is not a statement that the agent must discover every unknown defect.

For example, if the seller tells the agent about concealed foundation damage and the stated inspection test is met, a written secrecy request does not make that physical fact confidential. A private minimum acceptable price concerns negotiation and calls for a different analysis.

Do not mix up the misinformation standards

When passing a customer's information to a client, 15-15(d) uses knew or should have known the information was false. When passing the client's information to a customer, 15-25 describes protection where the licensee lacked actual knowledge of its falsity. These are different provisions, not a general license to repeat suspicious claims. Section 15-15(e) preserves common-law duties concerning negligent or fraudulent material misrepresentation.

What information is confidential, and what must be disclosed?

The 1-10 definition covers information obtained from a client during the brokerage-agreement term that the client made confidential by written request or instruction, that concerns the client's negotiating position, or whose disclosure could materially harm that position. A private price ceiling can qualify without a separate written secrecy request.

The definition recognizes client permission by words or conduct, disclosure required by law, and information becoming public through a source other than the licensee. Material information about the property's physical condition is excluded from confidential information.

Under 1450.800, take reasonable steps to safeguard confidential information. Under 15-50(b)-(c), the sponsor must protect it, and the designated agent may share it with the sponsor or the sponsor's specified people to obtain advice or assistance for that client's benefit. The sponsor or specified representative must not pass it on unless the Act requires it or the original client requests or permits it. That permission to seek advice is not an invitation to brief the opposing designated agent.

Stigmatized property is a separate question

15-20 and 1450.810 provide no cause of action for failing to disclose the specified occupant medical conditions or an occurrence, such as murder or suicide, that did not affect the property's physical condition, environment or structures. They also address fact situations on other property and other-property physical conditions without a substantial adverse effect on the subject property's value.

Do not use that rule for a fire's remaining structural damage or an environmental condition that actually affects the subject property. Nondisclosure protection is not permission to answer a customer dishonestly.

When is dual agency allowed in Illinois?

Only with informed written consent from all clients, followed by the required transaction confirmation. 15-45 treats the initial disclosure, consent and later confirmation as separate steps. A client need not consent.

The statutory disclosure allows property information, known latent-defect disclosure, buyer financial qualifications, explanations of real estate terms and closing procedures, help arranging inspections, comparison of financing alternatives and comparable-sale information. It does not allow the agent to suggest the buyer's offer price or terms or the seller's counteroffer or acceptance terms. Permission to disclose a client's private limit does not permit that prohibited negotiating advice. Sharing confidential information needs permission unless another statutory disclosure exception applies.

Ownership is an express bar

Under 15-45(g) and 1450.820, the licensee cannot be dual agent if the licensee, or an entity in which the licensee has or will have any ownership interest, is a transaction party. The rule includes direct and indirect interests. Both clients signing consent does not remove this prohibition.

Section 15-45(e) limits dual-agency knowledge to actual knowledge and rejects automatic imputation among the clients, brokers and affiliated licensees. It does not erase the specific misinformation standards or authorize deliberate concealment.

If a client declines dual agency, 15-45(f) allows withdrawal from that representation under the stated conditions. A referral fee for that withdrawal requires written disclosure to both the withdrawing client and the client who remains represented. For a focused comparison, see Illinois designated versus dual agency.

What if two buyer clients want the same property?

Under 1450.830, contemporaneous offers involve two or more clients represented by the same designated agent, the same parcel or unit, and offers the agent knows or has reason to know the owner or representative will consider at the same time.

Give written disclosure to those clients and refer a requesting client to another designated agent. The rule allows physical or electronic notice. It does not require automatic reassignment of every client: referral follows a client's request. Do not reveal one client's confidential price ceiling or private terms to the other. Two competing buyers do not automatically create buyer-seller dual agency.

What changes when representation ends?

Under 15-30, accounting for transaction money and property and preserving confidential information are the default surviving duties after termination, expiration or completed performance. Check what the written agreement provides. Do not assume expiration permits disclosing the former client's negotiating information.

Two other Article 15 boundaries matter: 15-55 and 15-60 reject subagency based only on MLS affiliation and prohibit an MLS offer of subagency. They also state that a consumer is not vicariously liable for the licensee's acts or omissions in providing licensed activities on that consumer's behalf. This does not excuse a consumer's own conduct.

Use Article 15's statutory framework for Illinois questions. Its displacement of common-law agency concepts in 15-5 does not wipe out the material-misrepresentation duties expressly preserved by 15-15(e).

Illinois agency practice questions

Choose an answer before opening the explanation. These original study scenarios test the cited rules; they are not actual PSI questions or a prediction of your exam score.

1. Whom each agent represents

Lena is named as the seller's designated agent. Marco, at the same sponsoring brokerage, is named as the buyer's designated agent. Neither represents the other client. Does their shared brokerage alone make this dual agency?

No. The individual designations allow separate representation within the same firm.
Yes. Every licensee automatically represents all of the firm's clients.
Yes, if the seller funds both brokers' compensation.
No, so the agents may exchange the clients' private negotiating limits.

Show answer and explanations

Answer: A. No. The individual designations allow separate representation within the same firm.

Correct. Section 15-50 excludes the firm's other licensees from each designation and does not treat the sponsor as acting for multiple parties when the specified conditions hold.
Why this misses: That ignores designated agency's exclusion of other affiliated licensees.
Why this misses: Payment does not determine agency under 15-40.
Why this misses: Separate designation preserves confidentiality. It does not authorize sharing opposing clients' private limits.

Change the facts: If Lena herself represents both buyer and seller in the transaction, analyze dual-agency consent and restrictions. A second agent's presence does not erase Lena's own conflicting relationships.

2. The disclosure clock

A seller's listing agent starts working with an unrepresented buyer who is about to disclose the highest price they can pay. No offer has been prepared. May the agent postpone written no-agency notice until an offer is signed?

Yes, because no-agency notice is due only at contract signing.
Yes, if the agent privately intends to remain loyal to the seller.
Yes, if the buyer has not agreed to pay the agent.
No. Give written notice now to prevent the buyer's mistaken confidential disclosure.

Show answer and explanations

Answer: D. No. Give written notice now to prevent the buyer's mistaken confidential disclosure.

Why this misses: The outside deadline is offer preparation, and the rule also aims to prevent an earlier confidential disclosure.
Why this misses: An undisclosed intention does not supply the written notice owed to the customer.
Why this misses: A compensation promise does not determine representation or remove the notice duty.
Correct. Waiting for offer signing misses both the protective purpose and the latest statutory boundary.

Change the facts: If the buyer is already separately represented, that does not make the listing agent the buyer's agent. Identify each licensee's relationship rather than using unrepresented as a synonym for customer.

Source: 15-35(c); 1450.770(i)(1)

3. Confidentiality and physical facts

A seller tells the listing agent about concealed foundation damage that materially affects the house. The agent knows a reasonably diligent buyer inspection would not reveal it. The seller writes, 'Keep this confidential.' What should the agent do for prospective buyer customers?

Keep it secret because every written confidentiality instruction controls.
Timely disclose the actually known latent material adverse physical fact.
Disclose it only after a buyer becomes the agent's client.
Wait until closing because the buyer can cancel then.

Show answer and explanations

Answer: B. Timely disclose the actually known latent material adverse physical fact.

Why this misses: Material information about the property's physical condition is excluded from the statutory definition of confidential information.
Correct. All elements of the seller-agent disclosure duty in 15-25 are given. A confidentiality label does not remove that duty.
Why this misses: The stated duty protects prospective buyer customers of the seller's agent.
Why this misses: Section 15-25 requires timely disclosure, not a general closing-day deadline.

Change the facts: A seller's private minimum acceptable price is a different kind of information. It concerns negotiating position and is generally protected unless an applicable disclosure exception applies.

4. Two stages of dual consent

Both clients previously gave informed written consent to dual agency. Their purchase contract includes a transaction-specific confirmation of that prior consent. Both sign the contract, but neither initials the confirmation provision. What is missing under 15-45(c)?

Nothing. A contract signature always replaces separate initials.
Only an oral assurance from the sponsoring broker.
The clients must also initial the embedded dual-agency confirmation provision.
A written promise that the dual agent will recommend the buyer's offer price.

Show answer and explanations

Answer: C. The clients must also initial the embedded dual-agency confirmation provision.

Why this misses: When confirmation is inside another document, the statute expressly calls for both the document signature and initials on the confirmation provision.
Why this misses: The required confirmation comes in writing from the clients. The broker's assurance does not replace it.
Correct. Prior written consent and the signed contract do not dispense with the specified initials for an embedded confirmation.
Why this misses: The statutory dual disclosure identifies recommending a buyer's offer price or terms as a prohibited service.

Change the facts: A separate confirmation document is different from an embedded provision. The special sign-plus-initial instruction here addresses confirmation included in another document.

Source: 15-45(b)-(c)

5. One agent, competing clients

One designated agent prepares offers for two buyer clients on the same condominium. The agent knows the seller will consider both offers tonight. After receiving notice, one client asks for another designated agent. What is required?

Written disclosure to both affected clients and referral of the requesting client to another designated agent.
Automatic dual agency because there are two buyers.
Tell each buyer the other's exact offer and financing limits.
A referral only if the agent believes it will improve the client's offer.

Show answer and explanations

Answer: A. Written disclosure to both affected clients and referral of the requesting client to another designated agent.

Correct. The same agent, same unit and same-time consideration meet the contemporaneous-offer definition. The referral follows the client's request.
Why this misses: Two competing buyer clients are not the buyer-and-seller or landlord-and-tenant combination that defines dual agency.
Why this misses: The notice obligation does not authorize disclosure of confidential negotiating terms.
Why this misses: The rule ties referral to the client's request, not the agent's assessment of likely success.

Change the facts: Offers on different units do not meet this rule's same-parcel-or-unit definition merely because they are considered on the same evening. Other duties still apply.

Source: 1450.830; 15-15(b)

6. A prohibition consent cannot cure

A listing agent holds an indirect ownership interest in the LLC buying the listed property. Both clients are willing to sign dual-agency consent. May the agent act as dual agent in this purchase?

Yes, because unanimous consent cures every conflict.
Yes, because the LLC rather than the agent signs the purchase contract.
Yes, if the agent receives no commission.
No. The ownership interest in a party entity prohibits this dual agency.

Show answer and explanations

Answer: D. No. The ownership interest in a party entity prohibits this dual agency.

Why this misses: This is an express prohibition, not simply a conflict that informed consent resolves.
Why this misses: The rule covers a party entity in which the licensee has or will have an ownership interest, directly or indirectly.
Why this misses: Waiving compensation does not remove the ownership-based dual-agency prohibition.
Correct. The rule includes indirect ownership, with no minimum percentage in this prohibition.

Change the facts: Removing the ownership fact removes this particular prohibition. It does not by itself establish informed written consent, a buyer brokerage agreement or transaction confirmation.

Source: 1450.820; 15-45(g)

7. Required writing and legal remedies

A brokerage has performed licensed work but failed to put its claimed client relationship in the required written brokerage agreement. May it rely on the missing writing alone as an affirmative defense that no agreement or licensed activity existed?

Yes. Missing writing conclusively proves no licensed work occurred.
No. Section 15-50(a-5) preserves the client's ability to seek enforcement and the court's remedies.
Yes. Courts can never consider an oral agreement in an Illinois brokerage dispute.
No, because all oral agreements automatically earn the broker a commission.

Show answer and explanations

Answer: B. No. Section 15-50(a-5) preserves the client's ability to seek enforcement and the court's remedies.

Why this misses: A missing document does not erase what the parties agreed or what work was actually performed.
Correct. The writing requirement remains. The section specifically prevents absence of writing from becoming the stated affirmative defense.
Why this misses: Subsection (a-5) expressly preserves a client's ability to seek enforcement of an oral agreement and legal or equitable remedies.
Why this misses: Preserving the client's remedies is not an automatic ruling on the broker's compensation or every oral agreement's enforceability.

Change the facts: A signed agreement improves the record of the relationship, but does not excuse late disclosures, prohibited dual agency or a breach of the client's duties.

Illinois agency relationships FAQ

What is the default agency relationship in Illinois?

Under 15-10, a licensee is considered the designated agent of the consumer the licensee is working with unless a written agreement between the sponsoring broker and consumer provides a different relationship. Read this with the written brokerage-agreement and disclosure duties. Missing paperwork does not automatically prove there was no relationship.

Is a designated agent the same as a designated managing broker?

No. A designated agent is named as a client's legal agent. A designated managing broker has office supervision responsibilities and is appointed by the sponsoring broker. A supervisory title does not automatically make that person every client's designated agent.

Can the same Illinois brokerage represent the buyer and seller?

Yes. Separately designated licensees may represent the opposing clients without either individual being a dual agent. If one licensee represents both sides in the same transaction, dual-agency consent and restrictions apply. Confidentiality remains necessary in either arrangement.

Can the listing agent help a buyer without representing them?

Yes. Under 1450.770(i)(1), a licensee with an executed seller or owner listing agreement may perform licensed activities on that client's behalf with an unrepresented buyer or tenant after written no-agency disclosure. Helping with a seller's transaction does not authorize undisclosed advocacy for the buyer.

Does the person paying the commission become the agent's client?

Payment or a promise of payment does not determine agency under 15-40. Find the designated relationship, agreement and disclosures. A seller-funded buyer-broker payment does not, by itself, make the buyer's agent the seller's agent.

Does a no-agency disclosure replace a buyer brokerage agreement?

No. No-agency notice tells a customer that this licensee does not represent them. A buyer brokerage agreement records the represented relationship and its terms. A licensee moving into dual representation must meet the additional agreement and consent requirements before performing licensed activities for that buyer.

Can a dual agent recommend what price I should offer?

The statutory dual-agency disclosure says the agent cannot recommend or suggest the buyer's offer price or terms, or the seller's counteroffer or acceptance terms. The agent can provide comparable-sale information so the clients make their own decisions. Permission to share a client's private limit does not authorize prohibited price advice.

What if a client refuses dual agency?

The client need not consent, and the licensee cannot proceed as that client's dual agent without it. Section 15-45(f) allows the licensee to withdraw from representing a nonconsenting client without liability under that provision, while preserving the ability to represent the other client in this transaction or the withdrawing client in others. A referral fee connected with that withdrawal needs written disclosure to both clients identified in the statute.
