Customer in real estate
A buyer can be a client to the buyer's agent and a customer to the seller's agent in the same transaction. Start with the particular licensee: who does that person represent?
Last reviewed:
The short answer
In Illinois, a customer is a consumer whom a particular real estate licensee does not represent. That person may have another agent. Customer status does not remove the licensee's honesty, false-information or applicable disclosure duties. It also does not automatically provide the client advocacy that representation involves.
The PSI national outline places customer and nonclient duties in VI.B.2, within the whole 13-of-100-question Agency area. Illinois agency relationships also appear in state II.A. Neither is a quota for this term. Reviewed October 26, 2026. These are original examples and questions, not released PSI questions.
Identify the relationship, then apply the duty
- Name the licensee and represented person. Customer is a relationship-specific term. A customer of one licensee can be a client of another; buyer, seller and tenant are transaction roles, not automatic agency classifications.
- Check the actual relationship and writing. Section 15-10 establishes the designated-agency default for the consumer a licensee works with, unless the sponsoring broker and consumer have a written agreement for a different relationship. Do not infer no agency merely from an unsigned or missing form.
- Give the applicable notice on time. Section 15-35(c) requires written nonrepresentation disclosure at a time intended to prevent confidential disclosure and no later than preparing a purchase or lease offer. For the listing-side situation in rule 770(i)(1), give it before the specified assistance, not merely before an eventual offer.
- Treat the customer honestly. Section 15-25 prohibits negligent or knowing false information. Its separate physical-fact sentence applies to a licensee engaged by a seller client dealing with prospective buyer customers and has several precise conditions.
- Keep assistance and advocacy distinct. Under 770(i)(1), the licensee with an executed seller/owner agreement can perform the specified activities on that side with an unrepresented buyer or tenant after written notice. Switching to dual representation requires the separate agreement and consent requirements; helping with a transaction is not permission to change sides silently.
| Question | Illinois rule or distinction | What to avoid |
|---|---|---|
| Represented by this licensee? | Customer means no representation by that licensee | Assuming customer means no agent anywhere |
| No signed buyer form? | Apply the statutory default and actual written relationship | Automatically declaring no agency |
| Notice for listing-side assistance? | 770(i)(1) requires written nonrepresentation notice first | Waiting until offer preparation as a universal rule |
| False information? | Honesty; no negligent or knowing false information | Inventing or knowingly repeating a false fact |
| Known hidden physical fact? | Apply every condition in 15-25's seller-licensee duty | Treating every rumor or visible issue as that trigger |
| False information supplied by the client? | Specific protection turns on source and lack of actual knowledge | Treating attribution alone as universal immunity |
| Private information received? | Assess confidentiality, authority and applicable privacy law | Assuming a nonclient's documents may be shared freely |
| Who pays the compensation? | Payment or its promise does not determine agency | Classifying the relationship from the payor alone |
The distinctions that matter
| Distinction | How it works | What to notice |
|---|---|---|
| Customer and unrepresented buyer | A customer is not represented by the licensee being discussed. An unrepresented buyer has no buyer representation in the stated situation. Those descriptions can overlap, but are not identical. | Ask, "Customer of which licensee?" |
| Client duties and customer protections | Representation carries the applicable client duties in 15-15. Customer status still carries honesty, false-information and other applicable protections. It does not grant the opposing client's advocacy or private negotiating information. | No representation does not mean no duty. |
| The statutory outer deadline and an earlier rule | Section 15-35(c) says no later than offer preparation, with a preventive confidentiality purpose. Rule 770(i)(1) addresses a particular listing-side assistance situation and requires written notice before it. | Use the earlier applicable requirement. |
| Actually known latent physical facts and every possible defect | The seller-client/prospective-buyer-customer sentence requires actual knowledge of a latent material adverse physical fact not discoverable by the customer's reasonably diligent inspection, with timely disclosure. It is not a guarantee of all unknown conditions. | Read every relationship, knowledge and condition qualifier. |
| Client-provided false information and the licensee's own false statement | Section 15-25 specifically protects the licensee from customer liability for client-provided false information when the licensee lacked actual knowledge it was false. That is not blanket immunity for the licensee's own false claims or knowing repetition. | Do not erase either the general prohibition or the specific protection. |
| Agency confidentiality and privacy | Do not promise an opposing agent's client confidentiality for every negotiating statement. Separately, lack of representation is not blanket authority to disclose financial documents or ignore applicable data safeguards. | Explain the role before inviting private strategy; protect records under the actual rules. |
Work through the facts
One buyer, two different relationships
Alex has a buyer agent. Morgan is the designated seller agent and does not represent Alex.
- Alex is the buyer agent's client.
- Relative to Morgan, Alex is a customer.
Answer: Alex need not be unrepresented everywhere to be Morgan's customer.
A form has not been signed
A licensee works with a buyer and says, "You are automatically just a customer because we have not signed anything." The actual relationship and required writings have not been assessed.
- Section 15-10 supplies a designated-agency default.
- Missing paperwork is not itself the statutory written different-relationship agreement.
Answer: Do not use the unsigned form as an automatic no-agency rule. Resolve the actual relationship and required documentation.
The listing-side notice is deferred
A licensee has an executed seller listing agreement and starts the licensed assistance described in 770(i)(1) with an unrepresented buyer, planning to give written nonrepresentation notice only when an offer is prepared.
- This particular rule permits the assistance after the written disclosure.
- The later offer deadline is not a safe harbor for earlier conduct.
Answer: Give the required written notice before that assistance. Do not wait until offer preparation on these facts.
A known concealed water problem
A seller-engaged licensee actually knows a latent material adverse physical water-entry problem. On the supplied facts, the prospective buyer customer's reasonably diligent inspection would not discover it.
- The relationship and every condition in the specific 15-25 sentence are supplied.
- A seller instruction to keep quiet does not remove the disclosure duty.
Answer: Timely disclose the covered fact. Material physical-condition information is excluded from the Act's client-confidential-information definition.
An obvious crack is not permission to lie
A window crack would be discovered by the buyer customer's reasonably diligent inspection. The licensee nevertheless knowingly says the glass is intact.
- The stated crack is not latent under that inspection test.
- The separate prohibition on knowingly giving false information still applies.
Answer: Do not make the false statement. Failure of the latent-fact test does not eliminate the honesty duty.
A client supplies incorrect roof information
The client tells the licensee the roof is five years old. The licensee passes that information to the customer without actual knowledge of its falsity. It is actually 12 years old.
- The false information came from the licensee's client.
- The facts supply lack of actual knowledge, the specific statutory protection's knowledge condition.
Answer: Apply the client-source protection as written in 15-25. It does not grant immunity for every other statement or claim, and merely naming a source would not cure knowing repetition.
A financial file from a customer
A customer gives the licensee a financial document for a specified transaction purpose. Someone proposes sharing it publicly because the customer is not this licensee's client.
- Agency classification alone does not supply disclosure authority.
- Applicable privacy and security rules have their own scope; a client-confidentiality label is not the only possible protection.
Answer: Check authority, purpose and applicable safeguards. Do not assume that no agency makes the file public, or promise client negotiating confidentiality for every customer statement.
Mistakes to avoid
- Every buyer who speaks to the listing agent is that agent's client. Identify actual representation by the particular licensee.
- No signature means no agency. Apply the statutory default and the actual relationship and writings.
- No-agency notice can always wait until the offer. Use the preventive statutory purpose and any earlier applicable rule, including 770(i)(1).
- The customer receives no legal protection. Honesty, false-information and applicable disclosure and privacy duties remain.
- Every defect question has the same answer. Separate the specific latent-fact disclosure sentence from honesty, seller reporting and other law.
- A source label always prevents liability. Read the actual client-source and knowledge conditions; do not convert them into blanket immunity.
Check your understanding
These are original teaching questions, not recalled or predicted PSI questions. Answer first, then explain why the other choices fail.
1. A buyer has a buyer agent, while a particular seller agent does not represent that buyer. Relative to the seller agent, the buyer is what?
- A client merely because a showing occurs
- Automatically a dual-agency client
- Neither a consumer nor customer
- A customer
Show answer and explanation
Answer: D. A customer
Customer means a consumer not represented by the particular licensee. The buyer can simultaneously be another agent's client.
2. A licensee declares a buyer automatically unrepresented solely because a buyer form is unsigned. Which provision must be considered?
- A rule that buyers cannot be clients
- Section 15-10's designated-agency default and written different-relationship condition
- A rule that unsigned always means no agency
- A rule that payment always establishes agency
Show answer and explanation
Answer: B. Section 15-10's designated-agency default and written different-relationship condition
Do not replace the current statutory relationship rule with an automatic missing-signature exception.
3. On the exact listing-side facts of 770(i)(1), when is the written nonrepresentation disclosure required?
- Before the specified assistance
- After an accepted offer
- Only when compensation is collected
- Only when the price is negotiated
Show answer and explanation
Answer: A. Before the specified assistance
The licensee has an executed seller/owner agreement and deals with an unrepresented buyer or tenant on that side after written notice. The outer offer-preparation deadline does not postpone this requirement.
4. What does 15-35(c) say about customer nonrepresentation notice?
- The first inspection is always the deadline
- An oral explanation always suffices
- It is needed only after a consumer shares a secret
- Written notice at a time intended to prevent confidential disclosure, never later than offer preparation
Show answer and explanation
Answer: D. Written notice at a time intended to prevent confidential disclosure, never later than offer preparation
Apply that statutory purpose and outer deadline, plus any earlier applicable requirement. The section covers an offer to purchase or lease.
5. A seller agent knowingly tells a customer an obvious cracked window is intact. Which answer is sound?
- A visible condition permits any statement about it
- The knowing false-information prohibition still applies
- Only latent conditions can ever involve dishonesty
- A seller instruction authorizes the false statement
Show answer and explanation
Answer: B. The knowing false-information prohibition still applies
The special latent-fact sentence and the general honesty/false-information duties are separate. A visible crack does not make a knowing falsehood permissible.
6. Which supplied facts match the specific physical-disclosure sentence in 15-25?
- Any unknown condition an expert could theoretically find
- Seller-client engagement, prospective buyer customer and actually known latent material adverse physical facts not discoverable by reasonably diligent customer inspection
- Only a customer's price preference
- Every rumor about any property
Show answer and explanation
Answer: B. Seller-client engagement, prospective buyer customer and actually known latent material adverse physical facts not discoverable by reasonably diligent customer inspection
Timely disclosure is required on the complete supplied conditions. Do not omit the relationship, actual knowledge, physical nature or inspection qualification.
7. Under 15-25's specific false-information protection, which combination matters?
- A seller's demand to repeat a known lie
- Any online source and a disclaimer
- Information supplied by the licensee's client, with no actual knowledge it was false
- The licensee's own invented fact and a source label
Show answer and explanation
Answer: C. Information supplied by the licensee's client, with no actual knowledge it was false
The statute states those source and actual-knowledge conditions. Do not turn it into immunity for the licensee's own claims or knowing false information.
8. A client supplies a roof-age statement, but the licensee actually knows it is false. Does simply saying "the seller says" establish the specific protection?
- No; the lack-of-actual-knowledge condition is absent
- Yes, if said before an offer
- Yes, attribution cures all claims
- Yes, if the client is paying
Show answer and explanation
Answer: A. No; the lack-of-actual-knowledge condition is absent
A source label does not restore the condition that the licensee lacked actual knowledge of falsity.
9. A seller contributes money toward a buyer broker's compensation. What alone can that fact establish about agency?
- The buyer broker necessarily represents the seller
- The listing agent necessarily represents the buyer
- Payment alone does not determine agency
- All parties automatically consent to dual agency
Show answer and explanation
Answer: C. Payment alone does not determine agency
Section 15-40 separates payment or its promise from the agency determination. Other compensation and relationship requirements still apply.
10. A listing licensee wants to start acting as a dual agent under 770(i)(2). Which answer fits the required sequence?
- Begin buyer advocacy first and decide consent later
- A later closing signature cures every earlier action
- Execute the buyer/tenant brokerage agreement and comply with 15-45 before licensed activities on that party's behalf
- A no-agency notice alone authorizes it
Show answer and explanation
Answer: C. Execute the buyer/tenant brokerage agreement and comply with 15-45 before licensed activities on that party's behalf
The dual-agency route has separate agreement and informed-consent requirements. Listing-side assistance does not automatically authorize it.
11. A consumer is a customer, not this licensee's client. What follows about the consumer's financial records?
- Assess applicable privacy, safeguards and disclosure authority separately
- No data law can protect a nonclient
- They automatically become public
- They may be posted without permission because no agency exists
Show answer and explanation
Answer: A. Assess applicable privacy, safeguards and disclosure authority separately
Agency classification does not provide blanket authority to expose a nonclient's records. It also does not promise client negotiating confidentiality for every statement.
12. Does the specific 15-25 physical-fact sentence make a licensee a guarantor of every hidden condition or require the licensee to perform a professional home inspection?
- Yes, if the customer has no agent
- No; apply its actual-knowledge and disclosure conditions without erasing other duties
- Yes, regardless of actual knowledge
- Yes, if the seller asks
Show answer and explanation
Answer: B. No; apply its actual-knowledge and disclosure conditions without erasing other duties
The sentence addresses specified known facts and disclosure. Other duties can still require care in statements and appropriate referrals; this is not a universal no-duty-to-investigate rule under every law.
Common questions
Can I have an agent and still be someone else's customer?
Yes. You can be your buyer agent's client and the seller agent's customer. The statutory definition is relative to the particular licensee, not a declaration that nobody represents you.
Does an unsigned buyer agreement automatically mean customer status?
No. Apply 15-10's designated-agency default, the actual relationship and the required written different-relationship arrangement. Missing documentation is a compliance issue to resolve, not an automatic statutory no-agency exception.
When must a listing agent give an unrepresented buyer nonrepresentation notice?
On the facts covered by 770(i)(1), after an executed seller/owner agreement and before the specified listing-side assistance. Section 15-35(c) separately requires written customer notice at a time intended to prevent confidential disclosure and no later than preparation of a purchase or lease offer.
Can a listing agent transmit a customer's offer without representing the buyer?
Lawful listing-side assistance can occur under its actual requirements. It does not by itself make the agent the buyer's advocate or authorize dual representation. Confirm the relationship, required written notice and the activity being performed.
What protection does a customer receive under 15-25?
Honest treatment and no negligent or knowing false information. The section also gives a precise seller-licensee duty to prospective buyer customers for actually known latent material adverse physical facts not discoverable by reasonably diligent customer inspection, with timely disclosure.
Does an obvious problem remove the honesty duty?
No. A fact discoverable through the stated reasonably diligent inspection may fail the latent-fact condition. That does not authorize a false statement about it or erase another applicable duty.
Can the seller make a known physical defect confidential?
Material physical-condition information is excluded from the statutory client-confidential-information definition. A request for secrecy does not remove a disclosure obligation. Apply the actual facts and legal conditions rather than assuming every suspicion establishes the same duty.
Is a licensee always liable for a client's false information?
Section 15-25 specifically protects a licensee from customer liability for client-provided false information when the licensee did not actually know it was false. It is not blanket immunity for the licensee's own false statements, knowing repetition or every different legal claim.
Does writing "seller says" make every statement safe?
No. Attribution can explain a source, but it does not cure actual knowledge that the statement is false. Read the statute's actual client-source and knowledge conditions; do not substitute a disclaimer for them.
Does no agency mean every piece of customer information may be shared?
No. Explain the role before inviting private negotiating details, and assess applicable confidentiality, privacy and data safeguards. A customer relationship does not grant blanket permission to publish financial documents or use them for an unauthorized purpose.
Does paying commission make someone a client?
Payment or its promise does not determine agency under 15-40. Identify the actual representation and required agreements and disclosures. This does not waive rules governing how compensation may be paid or accepted.
Does a seller's report replace the licensee's own known-fact duty?
No. If the supplied facts establish the seller-engaged licensee's 15-25 disclosure conditions, a seller report does not remove that duty. A licensee who actually knows a covered fact cannot rely on the client-source false-information protection as though the knowledge were absent. Seller reporting also has its own statutory rules.
Does 15-25 protect a licensee who makes a required disclosure?
Its final sentence says no cause of action arises against a licensee for revealing information in compliance with that section. The compliance qualification matters. Do not turn it into permission for any publication, false statement or unauthorized disclosure.
