Illinois disclosures topic guide
Illinois seller disclosure and material defects
A seller report can be accurate when signed and still need an update before closing. It can also arrive too late to satisfy the law. For an Illinois exam question, separate what the seller knew, when the buyer received it and which remedy the facts support.
Last reviewed:
The short answer
In a covered Illinois residential transfer, the seller completes the statutory report and delivers it before contract signing. Disclose actually known material defects, complete every item and correct known errors before closing. The report is not an inspection or warranty. A late initial report and a later supplement have different termination rules; a positive answer does not create the same cancellation right in every case.
Reviewed October 25, 2026 against the current Residential Real Property Disclosure Act, 765 ILCS 77, and the licensee duties in 225 ILCS 454/15-25. This guide covers exam principles, not the validity or deadline of a particular buyer notice. Separate contract provisions and other disclosure laws can also apply.
Work through coverage, knowledge, delivery and remedy
- Check the property, seller and transfer first. The Act covers specified residential real property and transactions, subject to the exact Section 15 exemptions. An investor, trust or inherited-property label alone does not finish that analysis.
- Use the seller's actual knowledge. A material defect substantially harms property value or significantly impairs future occupants' health or safety, subject to the form's reasonable-correction qualification. The Act does not require a special investigation to complete the report. Information already received can still establish knowledge. The form also asks specific factual and historical questions; do not replace their wording with a blanket current-defects-only test.
- Complete the current form. Section 35 has 24 numbered statements, beginning with occupancy and flood insurance. Do not call all 24 physical defects. Follow its explanation instructions and seller certification; a broker should not invent the seller's answers.
- Put receipt before contract signing. Section 20 sets the initial deadline. Section 50 permits specified personal, electronic and prepaid delivery methods, but effective delivery is upon receipt. Keep verifiable receipt evidence rather than treating the sent timestamp as conclusive.
- Update before closing. Under Section 30, a seller who becomes aware of an error, inaccuracy or omission in a delivered report or supplement must provide a written supplement using a Section 50 method. A new problem can make a previously accurate answer inaccurate.
- Choose the right remedy branch. Section 40(a) addresses a late initial report after all parties signed; Section 40(b) addresses a material defect in a supplement. Section 55 separately addresses a missing report and knowing violations. Do not convert one branch's five-business-day rule into every buyer's deadline.
| Event | Rule to use | Limit that matters |
|---|---|---|
| Initial report | Section 20: complete every item and deliver before signing | Receipt, not merely dispatch |
| Late initial report after all parties signed | Section 40(a): qualifying disclosure permits termination within five business days after receipt | Yes to items 1 or 2 alone does not supply this trigger |
| Known error discovered before closing | Section 30: written supplemental disclosure | Includes an error in an earlier supplement |
| Material defect in a supplement | Section 40(b): apply its three alternative conditions | No blanket five-day cancellation rule for every supplement |
| Repairable supplemental defect | Section 40(b)(iii): seller declines or fails to agree in writing to repair within five business days after delivery | An oral promise is not the specified written agreement |
| Termination under Section 40 | Written notice delivered to at least one seller using a Section 50 method | The Section 40 right ends at conveyance |
| Report withheld before conveyance | Section 55: buyer has a termination right | Do not confuse this with a merely positive timely report |
| Knowing violation or knowingly false report | Section 55: actual damages and court costs; reasonable attorney fees may be awarded to the prevailing party | No automatic fixed award or guaranteed fees |
| Action for violation of this Act | Section 60: one year from the earliest of possession, occupancy or recording | Not always one year after closing |
The distinctions that matter
| Distinction | How it works | What to notice |
|---|---|---|
| Covered housing and every building | The property definition includes one to four dwelling units, residential cooperatives, condominium units with qualifying exclusive limited common elements, and qualifying manufactured homes that are real property under the specified Act. | A sale of an entire five-unit building does not meet the one-to-four-unit category. A condominium unit has its own express coverage; do not confuse it with the whole building. A manufactured home must meet the specified real-property definition. |
| Never living there and the beneficiary exclusion | The Section 5 exclusion requires a beneficiary who both never occupied and never had management responsibility. It is not a blanket exemption for all absentee owners. | Check the person's legal capacity and both facts. |
| An inheritance transfer and a later resale | Section 15 exempts specified transfers from a decedent and qualifying fiduciary administration transfers. A later beneficiary resale requires its own analysis. | Do not carry an exemption forward automatically. |
| New construction and rehabilitation | Section 15(9) requires newly constructed residential property that has never been occupied. Rehabilitation of existing residential property is expressly excluded from that exemption. | A renovated house is not automatically exempt. |
| No special investigation and no knowledge | Section 25 does not require a specific inquiry to complete the report. It does require disclosure of material defects actually known. | An existing engineer report cannot be ignored merely because no new inspection is required. |
| A corrected problem and a hidden active defect | The form addresses current condition and has a qualification for previous problems reasonably believed corrected. Read each item as written: a historical-use or received-notice question is not erased by a general corrected-problem shortcut. | A fresh recurrence can undermine an earlier reasonable belief. |
| A late initial report and a supplement | Section 40(a) requires its late-report facts. A supplement uses the distinct conditions in Section 40(b), including prior knowledge, repairability and written repair agreement. | Identify the document before applying the remedy. |
| The seller report and the licensee's customer duties | Under Section 15-25, a seller's licensee must timely disclose actually known latent material adverse facts about physical condition that a reasonably diligent inspection would not reveal to a prospective-buyer customer. | The seller's signature does not erase the licensee's own knowledge; this is not a universal investigation warranty. |
| As-is terms and disclosure | The parties may negotiate an as-is sale, but those words alone do not create a Section 15 exemption or make knowingly false answers acceptable. | Repair allocation and disclosure compliance are different questions. |
| An Act claim and every possible claim | Section 60 sets the limit for an action under this Act. Section 45 preserves other statutory and common-law disclosure obligations and remedies. | Do not apply this Act's clock indiscriminately to every fraud or contract theory. |
Work through the facts
1. A landlord who never lived there
An individual owns and manages a covered duplex but has never lived in it. No Section 15 exemption applies. The owner argues that nonoccupancy alone eliminates the report.
- Nonoccupancy is not a blanket owner exemption.
- Even the separate beneficiary exclusion requires both no occupancy and no management responsibility.
Answer: The stated owner must comply; never living there is insufficient.
2. A renovated home
A seller extensively renovates a previously occupied house and calls it new construction. No other exemption applies.
- Section 15(9) excludes rehabilitation of existing residential property from its new-construction exemption.
Answer: Renovation alone does not establish this exemption.
3. An existing structural report
Before completing the report, a seller reads an engineer's finding of an unrepaired foundation condition that substantially harms the home's value. The seller says no new investigation was required.
- No special inquiry is required to complete the report.
- That does not eliminate actual knowledge of the described material defect.
Answer: Disclose the actually known defect; the no-investigation rule is not permission to ignore received information.
4. A truly late initial report
Both parties have signed by noon. At 1:00 p.m. the seller emails the initial report; verifiable buyer receipt occurs at 1:20 p.m. It discloses an unrepaired structural defect that substantially harms value. Conveyance has not occurred.
- All parties signed before receipt of the initial report.
- The report discloses a material defect, not merely occupancy or flood insurance.
- Section 40(a) permits termination within five business days after receipt, with the specified deposit return, using the required written notice.
Answer: The late-report branch applies. The sent time is not a substitute for effective receipt.
5. The only yes answers are occupancy and insurance
An initial report received after all parties signed has yes answers only to statements 1 and 2. Assume no other disclosed material defect.
- Section 40(a) expressly excludes those two numbered answers as its yes-answer trigger.
- The initial delivery still did not meet Section 20. Other applicable rights require separate facts.
Answer: Those answers alone do not establish Section 40(a) termination.
6. A new defect after a timely report
After a timely accurate report, a storm causes a material roof defect. The seller becomes aware before closing. It is repairable before closing and the seller agrees in writing to repair within five business days after delivery of the supplement. Assume no previously known report error. The seller has not declined repair during that period.
- A written supplement is required under Section 30.
- On these stated facts, none of Section 40(b)'s three termination conditions is established.
Answer: Do not infer automatic statutory cancellation just because the supplement discloses a defect. The contract and actual repair performance still matter.
7. An oral repair promise
A material defect first disclosed in a supplement is repairable before closing. Within the five-business-day period the seller offers only an oral promise; no written repair agreement is made. No conveyance has occurred.
- Section 40(b)(iii) specifies agreement in writing to repair.
- An oral promise alone does not satisfy that written-agreement condition.
Answer: The stated failure to agree in writing supports the Section 40(b)(iii) branch. A buyer still needs compliant written termination notice before conveyance.
8. A defect the seller already knew
A supplement reveals a material defect resulting from an omission the seller actually knew about when signing the prior report. The seller now offers a written repair agreement.
- Prior actual knowledge supplies the separate Section 40(b)(i) condition.
- The three conditions are alternatives, so a repair offer does not erase that stated condition.
Answer: Evaluate the prior-knowledge branch, not only whether repair was offered.
9. Early possession and later recording
For a Section 60 question only, assume possession starts October 20, 2026, occupancy starts October 22 and the conveyance instrument is recorded October 26.
- The earliest specified event is possession on October 20.
- A one-year anniversary comparison points to October 20, 2027, not October 26. Filing and any other legal timing issues need their own analysis.
Answer: The statutory starting event is October 20, 2026; this is not a universal deadline for every possible claim.
10. The broker knows more than the form says
A seller's licensee actually knows of a latent material adverse physical defect that a reasonably diligent inspection would not reveal to the prospective-buyer customer. The seller refuses to correct a false answer.
- The licensee has a separate timely disclosure duty under Section 15-25.
- Passing along the form or withdrawing does not itself substitute for that required disclosure.
Answer: Address the actual known fact and the separate statutory duty; do not treat the seller's signature as protection for silence.
Mistakes to avoid
- All 24 form statements are physical defects. The first two concern occupancy and flood insurance, and Section 40(a) treats them separately.
- Every trust, estate or investor sale is exempt. Match the exact seller definition and transfer exemption.
- No investigation means I can ignore the report I already read. Existing information can establish actual knowledge.
- Any yes answer gives every buyer five days to cancel. Apply the correct initial-report or supplement branch.
- Every supplement creates a five-day buyer deadline. The five days in Section 40(b)(iii) concern the seller's repair response; the statute does not simply repeat Section 40(a).
- The seller said it was repaired, so no future update is needed. A newly known error or recurrence before closing can require a written supplement.
- As-is removes all disclosure obligations. The Act and other law can still impose duties.
- A report proves there are no undiscovered defects. It is neither a warranty nor a substitute for a qualified inspection.
Check your understanding
These are original teaching questions, not recalled or predicted PSI questions. Answer first, then explain why the other choices fail.
1. An owner manages a covered duplex but never lived there. No transfer exemption applies. Which statement is best?
- The report is required only after possession.
- Only the buyer must complete the report.
- The owner must comply; nonoccupancy alone is insufficient.
- Nonoccupancy alone exempts every owner.
Show answer and explanation
Answer: C. The owner must comply; nonoccupancy alone is insufficient.
The Act does not grant every nonoccupant owner an exemption. The separate beneficiary exclusion also requires no management responsibility, and Section 15 must be analyzed separately.
2. Which fact fits Section 15(9), assuming its stated facts are true?
- An existing house was freshly painted.
- A rental owner has not personally lived in the building.
- A previously occupied home was completely rehabilitated.
- Newly constructed residential real property has never been occupied.
Show answer and explanation
Answer: D. Newly constructed residential real property has never been occupied.
The exemption concerns newly constructed property that has never been occupied. Rehabilitation of existing residential property is expressly excluded from this exemption.
3. A seller has read a reliable report identifying an unrepaired condition that substantially harms property value. What does the no-specific-investigation rule mean?
- No new investigation is required by this Act, but actually known material defects must be disclosed.
- The condition need not be considered if the sale is as-is.
- Only an inspector has knowledge.
- The seller may ignore information already received.
Show answer and explanation
Answer: A. No new investigation is required by this Act, but actually known material defects must be disclosed.
Section 25 removes the requirement for a specific inquiry to complete the report. It does not erase actual knowledge. The stipulated substantial adverse value effect supplies materiality here.
4. When must a covered seller deliver the initial written report under Section 20?
- Only if an inspection fails.
- Before the signing of a contract.
- Only after all parties sign.
- At any time within one year after recording.
Show answer and explanation
Answer: B. Before the signing of a contract.
Section 20 requires completion of all report items and delivery before contract signing. Under Section 50, delivery is effective upon receipt, not merely sending.
5. Both parties signed before the initial report was received. The report discloses a qualifying material defect and no conveyance has occurred. Which rule applies?
- Every buyer has 30 calendar days after mailing.
- Section 40(a) permits termination within five business days after receipt with its notice and deposit-return requirements.
- Only the supplement repair-response rule can apply.
- The report is necessarily a warranty.
Show answer and explanation
Answer: B. Section 40(a) permits termination within five business days after receipt with its notice and deposit-return requirements.
These are the late initial-report facts in Section 40(a). Compliant written termination is required, and the Section 40 termination right ends at conveyance. This is not the rule for every supplement.
6. A late initial report answers yes only to occupancy and flood insurance, with no other material defect disclosed. What follows under Section 40(a) alone?
- Occupancy is always a latent physical defect.
- There was necessarily timely delivery.
- All yes answers automatically trigger termination.
- Those two answers alone do not establish its trigger.
Show answer and explanation
Answer: D. Those two answers alone do not establish its trigger.
Section 40(a) excludes statement numbers 1 and 2 from its yes-answer trigger. Late delivery can still violate Section 20, and other rights require their own facts.
7. Before closing a seller discovers that a delivered report contains a known error. What does Section 30 require?
- Give only an oral assurance.
- Wait until recording.
- Ask the broker to erase the old report without replacement.
- Provide a written supplemental disclosure by a Section 50 method.
Show answer and explanation
Answer: D. Provide a written supplemental disclosure by a Section 50 method.
The update duty covers newly known errors, inaccuracies or omissions in a prior report or supplement before closing. A changed condition can make an earlier answer inaccurate.
8. A newly discovered supplemental material defect is repairable before closing. Within five business days after delivery, the seller agrees in writing to repair and has not declined repair. No earlier known error exists. Which answer is best on these facts?
- A written agreement is the same as proof the repair was completed.
- No Section 40(b) termination condition is established merely by that disclosure.
- Any supplement always gives the buyer five business days to cancel.
- The seller never needed a supplement.
Show answer and explanation
Answer: B. No Section 40(b) termination condition is established merely by that disclosure.
The stated facts establish neither prior knowing error, inability to repair before closing nor failure to agree in writing within the specified period. Contract rights and actual performance remain separate issues.
9. A supplemental material defect resulted from an omission the seller actually knew about when signing the prior report. The seller now offers a written repair agreement. Which distinction matters?
- Repair offers erase all previous knowledge.
- Section 40(b)(i) is an alternative condition that is not erased simply by offering repair.
- Only Section 40(a) can ever apply to a supplement.
- A buyer must wait until after conveyance to terminate under Section 40.
Show answer and explanation
Answer: B. Section 40(b)(i) is an alternative condition that is not erased simply by offering repair.
The three Section 40(b) conditions are alternatives. The prior actual knowledge condition must be evaluated independently of the repair-response condition. Written termination before conveyance is still relevant.
10. Which statement accurately describes delivery under Section 50?
- Receipt by one prospective buyer is deemed receipt for all, and delivery is effective upon receipt.
- Email dispatch is always effective receipt.
- Only personal hand delivery is valid.
- A buyer must always sign the report for any receipt to be provable.
Show answer and explanation
Answer: A. Receipt by one prospective buyer is deemed receipt for all, and delivery is effective upon receipt.
The section permits specified delivery methods, treats delivery to one buyer or an authorized individual as delivery to all buyers, and allows acknowledgment or other verifiable proof of receipt. Dispatch alone is not the statutory event.
11. For an action under this Act, possession is October 20, occupancy October 22 and recording October 26. Which event starts Section 60's one-year comparison?
- Only recording.
- The date an inspector later discovers damage.
- Always the latest event.
- The earliest specified event: possession on October 20.
Show answer and explanation
Answer: D. The earliest specified event: possession on October 20.
Section 60 uses the earliest of possession, occupancy or recording. The page does not resolve separate theories, filing rules or every possible tolling issue.
12. A seller's licensee actually knows a latent material adverse physical fact that a reasonably diligent inspection would not reveal to a prospective-buyer customer. The seller's report omits it. What is best?
- The buyer's customer status removes every licensee duty.
- The licensee must address the separate timely disclosure duty under Section 15-25.
- The seller signature extinguishes the licensee's knowledge.
- As-is terms always authorize silence.
Show answer and explanation
Answer: B. The licensee must address the separate timely disclosure duty under Section 15-25.
The seller report and the licensee's customer protections are distinct. Section 15-25 contains the stated actual-knowledge duty; it is not a universal requirement to discover every hidden defect.
Common questions
What must an Illinois seller disclose?
A covered seller completes all items in the statutory report and discloses material defects actually known. Use the exact questions and their explanation instructions rather than treating the form as a general promise that every feature works. Other statutes and common-law duties can also matter.
What is a material defect?
The Section 35 form uses a substantial adverse effect on property value or significant impairment of future occupants' health or safety, unless the seller reasonably believes the condition corrected. Not every cosmetic flaw necessarily meets that definition. The report also asks particular factual questions that must be answered as written. In particular, a history question such as known methamphetamine manufacture must be answered as written rather than skipped under a broad claim that every previous problem was corrected.
Does the seller have to order an inspection?
This Act does not require a specific investigation or inquiry to complete the report. That does not excuse a false answer about a defect already known. The buyer may seek a qualified inspection; lack of seller awareness is no guarantee a problem is absent.
How many statements are on the current Illinois disclosure form?
Section 35 has 24 numbered statements. Number 1 concerns occupancy within the last 12 months and number 2 concerns current flood hazard insurance. The remaining items address specified property matters. Do not memorize a claim that all 24 are physical-defect questions.
What subjects do the form questions cover?
They include flooding and floodplain status, structural and roof issues, building systems, water and waste systems, unsafe radon, asbestos and lead conditions, earth stability, insects and related structural damage, underground fuel tanks, boundary disputes, uncorrected violation notices and methamphetamine manufacture. Read each actual item: a question about a notice, history or condition is not interchangeable with a general material-defect label.
How should yes and not-applicable answers be explained?
The introductory instruction requires an explanation for yes or not applicable except statement 1. Item 1 separately asks a seller answering no to identify capacity or explain the relationship to the property. The additional-information direction also asks for explanations of yes or not-applicable entries. Follow the complete current form and use extra pages when needed instead of leaving an unexplained answer.
Are investor, trust and inherited-property sales exempt?
Not automatically. Section 5 has a specific beneficiary exclusion requiring both no occupancy and no management responsibility. Section 15 separately exempts defined fiduciary administration and decedent transfers, among others. A later resale is not necessarily the same transfer that was exempt when a beneficiary inherited.
Which other transfers are exempt?
Section 15 covers specified court-ordered and foreclosure-related transfers, qualifying fiduciary administration, transfers between co-owners, transfers from a decedent, transfers to a spouse or lineal relative, qualifying relocation-entity transfers, government transfers and never-occupied new construction. The relocation exemption requires making the prior seller report available. Rehabilitation is not the new-construction exemption. Exact facts and statutory wording control.
Does the Act cover a lease with an option to buy?
Section 10 includes a lease with an option to purchase, installment land sale contracts and specified ground-lease and beneficial-interest transfers, as well as sales and exchanges. Property, seller and Section 15 coverage still must be checked. It is not limited to a deed delivered at a conventional closing.
When does the buyer need to receive the report?
Before contract signing under Section 20. Section 50 makes delivery effective upon receipt and permits specified personal, electronic and prepaid mailing or delivery-service methods. Receipt may be acknowledged on the form, in the conveyance agreement or in another verifiable way. Sending and receiving are different events.
Can a buyer cancel after receiving a late initial report?
Section 40(a) applies when the initial report arrives after all parties signed and discloses a qualifying material defect, including a yes answer except numbers 1 and 2. It permits termination within five business days after receipt with return of the stated earnest money or down payment. Section 40 requires written notice delivered to at least one seller by a Section 50 method, and its termination right ends at conveyance.
Does every supplement create a five-day cancellation right?
No. Under Section 40(b), the material defect must involve an error the seller actually knew about when signing the prior disclosure, be unrepairable before closing, or be repairable but the seller declines or fails to agree in writing to repair within five business days after supplemental delivery. That repair-response period is not a blanket five-day buyer cancellation deadline. Section 40(c), the contract and other applicable rights also matter.
What if the seller never provides the report?
Section 55 gives the prospective buyer a termination right when the seller fails or refuses to provide it before conveyance. Knowing violations or knowingly false information can support actual damages and court costs; the court may award reasonable attorney fees to the prevailing party. A disputed claim does not establish an automatic award.
How long does a buyer have to sue under this Act?
Section 60 states one year from the earliest of possession, occupancy or recording of the conveyance instrument. It does not simply say one year after closing, discovery or the latest event. Section 45 preserves other law; a particular claim and filing question need individual legal analysis.
Do as-is terms or a seller report replace inspection and other disclosures?
No. The form permits negotiated as-is terms but says the report is not a warranty or an inspection substitute. As-is wording alone does not remove an applicable report duty or authorize deceit. Separate radon and lead requirements, contract contingencies and the licensee's actual-knowledge duties may also apply.
Are these official Illinois exam questions?
No. These are original teaching scenarios based on the cited current provisions. They help you distinguish coverage, knowledge, receipt and remedies. A practice percentage does not prove readiness or guarantee a pass.
