Illinois exam comparison
Listing agreement vs buyer brokerage agreement
The difference starts with the client: an owner hires a brokerage to market property; a buyer hires one to help acquire property. Both agreements define services, authority and payment.
Last reviewed:
What is the main difference?
A listing agreement serves the seller or owner. A buyer brokerage agreement serves the buyer. Each is a service contract with the sponsoring broker. Neither is the purchase contract between buyer and seller, and neither transfers title.
The sponsoring broker is the brokerage party; named designated agents perform the agreed work. In an exam question, identify the client first. Then read the services, authority, exclusivity and compensation rather than guessing from who found the property.
Compare the agreements side by side
| Question | Listing agreement | Buyer brokerage agreement |
|---|---|---|
| Who is the client? | Seller or owner | Buyer |
| What is the objective? | Market identified property for sale or lease | Assist with acquiring property within the agreed scope |
| What property terms matter? | Property identification and list price | The agreed search and service scope |
| Can it be exclusive? | Yes; read the listing type and any owner-sale exception | Yes; read the scope and any exceptions |
| What determines payment? | The agreed compensation basis, earning conditions and payment time | The agreed compensation basis, earning conditions and payment time |
| May the broker bind the client? | Not merely because a listing was signed | Not merely because a buyer agreement was signed |
Illinois's written-agreement rules cover exclusive and nonexclusive relationships. An open listing is not an exception to the writing requirement. See the listing-agreement definition and three common listing types for the owner-sale distinction.
When must the Illinois agreement be signed?
Seller or owner: before marketing or listing
Rule 1450.770(g) requires a written brokerage agreement before marketing or listing the owner's property. A sign, public advertisement or MLS listing should not go live while the signature is still promised.
Buyer or tenant: before assistance, or as soon as reasonably practical afterward
Subsection (h) requires the writing before engaging in licensed activities intended to assist a purchase or lease, or as soon as reasonably practical after performing them. Read that timing accurately. It is not permission to postpone the agreement until an offer or closing.
Arrange the writing early and follow the brokerage's applicable policies. The seller-side and buyer-side provisions use different wording; an exam answer should preserve that distinction.
What belongs in the writing?
The rule specifies the parties, designated agents, signatures, duties, compensation basis or amount, payment time and duration. Listing agreements also identify the property and list price and address compensation to cooperating brokers. Buyer agreements should make the agreed service scope clear.
For duration, the writing needs an automatic expiration date or, if it runs longer than one year, an annual termination right with thirty days' prior written notice. Compensation and payment-time changes need a signed written amendment. A purchase-contract form cannot be used to change previously agreed commission terms.
Each agreement must contain the rule's fair-housing statement. For residential property of four units or fewer, a protection-period clause must also provide the required exception when the client enters a valid written agreement with another sponsoring broker during that period.
Use the full Illinois brokerage-agreements lesson for the detailed requirements. This comparison helps classify the documents; the current rule controls the complete agreement.
Separate representation, exclusivity and compensation
Representation identifies whose interests the brokerage serves. Exclusivity identifies whether the brokerage has the sole representation right within the agreement's scope. Compensation identifies what earns a fee, its amount or basis, and when it is paid. One answer does not settle the other two.
Exclusive Illinois agreements must provide the Section 15-75 minimum services, including accepting and presenting offers and counteroffers, assisting with their development and negotiation, and answering related questions. Calling an agreement exclusive does not replace the required services.
A buyer agreement does not establish a standard commission rate or make the seller automatically responsible for payment. Read any provisions about credits or compensation from another source before deciding whether the buyer owes a balance.
Two examples that change the answer
Ruth lists her townhouse; Tomas hires a buyer's broker
Ruth's listing broker markets her townhouse and presents offers to her. Tomas's broker advises him within his buyer agreement and helps develop his offer. When Ruth and Tomas sign a purchase contract, the brokerage agreements continue to govern their respective service relationships.
Tomas's broker cannot sign the purchase contract for him merely because he signed a buyer agreement. Representation and authority to execute a contract are separate questions.
An unrepresented buyer visits the listing broker
A listing broker can perform the owner's licensed activities with an unrepresented buyer after providing the written no-agency disclosure required by Rule 1450.770(i). Showing the listing does not automatically make the visitor the broker's buyer client.
If that same licensee will also act for the buyer as a dual agent, a buyer writing and compliance with Section 15-45 are required before the buyer-side licensed activity. Both clients' informed written consent matters. A second signature alone is not the entire dual-agency process.
How does PSI test this distinction?
The national Agency outline VI.A includes listing contracts, buyer and tenant representation contracts, authority and termination. Illinois II.D covers brokerage agreements within the sixteen-question License Act category. PSI does not publish a separate question count for this comparison.
Read the stem in this order: client, objective, timing, authority, payment. A question about marketing before signature turns on timing. A question about signing an offer turns on authority. A question about a fee turns on the agreement's compensation terms.
Try three original questions
These are study questions, not reproduced PSI items.
1. Ruth hires a brokerage to market her townhouse. Tomas hires a different brokerage to help him buy a home. Which statement is correct?
- Both documents are purchase contracts
- Ruth has a listing agreement; Tomas has a buyer brokerage agreement
- Only Ruth's agreement needs to be written in Illinois
Show answer and explanation
Answer: B. The client and service objective identify the agreements. Each is a written brokerage service contract, separate from any later purchase contract.
2. An owner tells the broker to put the property on the MLS today and promises to sign tomorrow. What should the broker do?
- Obtain the written owner agreement before listing or marketing
- List it now because permission was spoken
- Wait for an offer before obtaining the writing
Show answer and explanation
Answer: A. Rule 1450.770(g) requires the seller or owner writing before marketing or listing. Oral permission does not satisfy that timing rule.
3. A buyer signs an agreement with a brokerage. What can you conclude from that fact alone?
- The seller owes the brokerage's fee
- The broker can sign an offer for the buyer
- The writing establishes the agreed brokerage relationship; authority and payment terms still need to be read
Show answer and explanation
Answer: C. Representation is not automatic power to bind the client, and it does not fix who pays. Those questions require the agreement and any separate authority or payment arrangements.
