Indiana Seller Disclosure Requirements: What Home Sellers Must Reveal

Indiana Seller Disclosure Requirements: What Home Sellers Must Reveal

Indiana law requires home sellers to complete a written disclosure form covering known defects and conditions that affect the property. The governing statute is IC 32-21-5 — the Indiana Residential Real Estate Sales Disclosure Law. Sellers who skip or lie on this form face legal liability, and buyers who don’t read it carefully risk expensive surprises after closing.

This guide explains exactly what Indiana sellers must disclose, what’s exempt, how the form works in practice, and what buyers should do with the information they receive. If you’re buying a home, our affordability calculator helps factor potential repair costs into your budget.

What Indiana Law Requires

Under IC 32-21-5, sellers of residential property with one to four units must provide a completed Sales Disclosure Form to the buyer before or at the time an offer is accepted. The seller must disclose all known material defects — they’re not required to conduct inspections or investigate problems they’re unaware of.

The key word is “known.” If a seller genuinely doesn’t know about a problem, they’re not liable for failing to disclose it. But if evidence shows they knew (or should have known based on obvious signs), failing to disclose can result in a lawsuit for fraud or misrepresentation.

The disclosure form is a standard document prescribed by the Indiana Real Estate Commission. It covers structural, mechanical, environmental, and legal aspects of the property. Sellers check boxes indicating whether each item is to their knowledge in working condition, has had problems, or is unknown to them.

What the Indiana Disclosure Form Covers

The standard Indiana Sales Disclosure Form covers the following categories:

Structural Components

• Foundation cracks, settling, or movement
• Basement or crawlspace water intrusion (past or present)
• Roof age, leaks, and repairs
• Structural modifications or additions (permitted and unpermitted)
• Wall, ceiling, or floor damage
• Chimney and fireplace condition
• Drainage problems on the property
• Grading issues that direct water toward the foundation

Mechanical Systems

• HVAC system age, condition, and known problems
• Plumbing — type of pipes, known leaks, water pressure issues
• Electrical system — panel capacity, known wiring issues, aluminum wiring
• Water heater age and condition
• Sump pump presence and operation
• Well and septic system condition (if applicable)
• Sewer connection and any known sewer line issues

Environmental Issues

• Radon — testing results, mitigation systems installed
• Lead-based paint (federal disclosure required for homes built before 1978)
• Asbestos — known presence in insulation, flooring, or other materials
• Mold — known or treated mold problems
• Underground storage tanks (current or removed)
• Soil contamination or environmental cleanup activity
• Flood zone status and flood history

Legal and Regulatory Issues

• Property boundary disputes or encroachments
• Easements and shared access agreements
• HOA membership, fees, and pending assessments
• Zoning violations or non-conforming use
• Pending litigation affecting the property
• Unpermitted improvements
• Code violations (current or past)
• Historic district restrictions

Pest and Wildlife Issues

• Termite damage — current or treated
• Termite treatment history and any active contracts
• Other wood-destroying insect damage
• Wildlife issues (bats, raccoons, etc.)

What Sellers Are NOT Required to Disclose

Indiana law does not require sellers to disclose:

• Deaths on the property: Indiana is not a stigmatized property disclosure state. Sellers don’t have to reveal if someone died on the property, including by murder or suicide. However, if a buyer asks directly, the seller should answer honestly.
• Sex offender registry: Sellers don’t have to disclose if registered sex offenders live nearby. Buyers can check the Indiana Sex Offender Registry independently.
• Paranormal activity: No requirement to disclose claims of haunting or supernatural events.
• Neighborhood nuisances: Noisy neighbors, barking dogs, and similar quality-of-life issues are not required disclosures.
• Future development: Sellers don’t have to disclose planned development nearby unless it directly affects the property (like a pending road widening that takes part of the lot).

Exemptions from the Disclosure Requirement

Not all property transfers require a seller disclosure under Indiana law. Exemptions include:

If you’re buying an exempt property (especially foreclosure or estate sales), you have no disclosure protection. A thorough home inspection becomes even more important — budget $400-$600 for a full inspection plus $200-$400 for a sewer camera scope. Consider our closing cost calculator to budget for inspection-related expenses.

The Disclosure Timeline

Indiana law specifies when the disclosure must be provided:

1. Before acceptance of offer: The ideal timing. Most listing agents include the completed disclosure form with the MLS listing so buyer agents can review it before writing an offer.
2. At the time of the offer: The seller can provide the disclosure simultaneously with the purchase agreement.
3. After acceptance: If provided after acceptance, the buyer has a right to rescind the offer within a specific time period after receiving the disclosure.

In practice, the disclosure should be available before you make an offer. If a listing doesn’t have a disclosure form available, ask the listing agent why. Possible reasons include: the seller hasn’t completed it yet (red flag for procrastination), the sale is exempt (foreclosure, estate), or the seller is avoiding disclosure (major red flag).

What Happens When Sellers Don’t Disclose

If a seller fails to disclose a known defect and the buyer discovers it after closing, the buyer has several legal options:

• Lawsuit for fraud or misrepresentation: If the seller knew about the defect and intentionally concealed it. The buyer must prove the seller had actual knowledge.
• Rescission: In some cases, the buyer can seek to undo the sale entirely, though this is rare and difficult to achieve.
• Damages: The buyer can sue for the cost of repairing the undisclosed defect, plus potentially diminished property value.
• Real estate commission complaint: If the seller’s agent knew about undisclosed defects, a complaint to the Indiana Real Estate Commission can result in license discipline.

Proving a seller knew about a problem requires evidence. Common evidence includes:

• Prior repair invoices or insurance claims
• Contractor testimony that they told the seller about the issue
• Physical evidence of concealment (fresh paint over water stains, carpet over cracked foundation)
• Neighbor testimony about known issues
• Previous listing disclosures (if the home was listed before with a different disclosure)

Indiana-Specific Disclosure Issues

Basement Water and Foundation Problems

Indiana’s clay soil, limestone karst geology, and high water tables make basement moisture one of the most common — and most commonly concealed — disclosure issues. Sellers must disclose known water intrusion, sump pump problems, and foundation cracks. Watch for signs of concealment:

• Fresh paint on basement walls (covering water stains or efflorescence)
• New carpet or flooring in basement (covering cracks or stains)
• Dehumidifier running during the showing (masking humidity)
• Stored items positioned to hide wall cracks
• Recently replaced sump pump (indicates recurring problems)

Radon Disclosure

Indiana is classified as Zone 1 by the EPA — the highest radon risk category. Sellers who have had radon testing done must disclose the results. If a mitigation system is installed, the seller must disclose that as well. However, sellers are not required to test for radon — they only have to disclose what they know.

Buyers should always request radon testing during the inspection period, especially in central and southern Indiana where levels frequently exceed the EPA action level of 4.0 pCi/L. Testing costs $150-$250, and mitigation (if needed) runs $800-$2,000.

Lead Paint Disclosure

Federal law (not just Indiana law) requires sellers of homes built before 1978 to provide a lead-based paint disclosure, give buyers a copy of the EPA pamphlet “Protect Your Family From Lead in Your Home,” and allow a 10-day inspection period for lead testing. This applies to all pre-1978 homes regardless of whether the seller knows lead paint is present.

In Indiana, pre-1978 homes are common — Indianapolis, Fort Wayne, South Bend, and Evansville all have large stocks of older housing. Lead paint disclosure violations carry federal penalties of up to $19,507 per violation.

Septic and Well Systems

Rural Indiana homes frequently use private well and septic systems. Sellers must disclose the type and known condition of both. Additionally:

• Many Indiana counties require a septic inspection before sale — check your county health department’s requirements
• Well water quality testing is recommended but not always required
• Some lenders (especially FHA and VA) require satisfactory well and septic inspections before approving the loan

Buyer’s Guide to Reading the Disclosure

Don’t just skim the disclosure form. Here’s how to use it effectively: A good inspection matters — read our guide on how to choose a home inspector in Indiana.

1. Read every line item. Don’t assume “no” answers are accurate — but they establish the seller’s legal position.
2. Pay attention to “unknown” answers. Multiple “unknown” responses on a long-term homeowner’s form is suspicious. An owner who’s lived in a home for 20 years should know whether the basement leaks.
3. Compare with the inspection. If the disclosure says “no water issues” but the inspector finds water stains, mineral deposits, or mold in the basement, you have a discrepancy to address.
4. Ask follow-up questions. The disclosure form is a starting point. Through your agent, ask the seller for details on any “yes” answers — when did the problem occur, what was done to fix it, who did the work?
5. Check for permits. If the disclosure mentions renovations or additions, verify permits were pulled with the local building department. Unpermitted work creates problems at resale and with insurance.

Seller’s Guide to Completing the Disclosure

Sellers: honesty on the disclosure form protects you more than it hurts you. Here’s why and how to do it right:

• Disclose everything you know. It’s better to disclose a problem and negotiate a lower price than to conceal it and face a lawsuit after closing.
• Be specific. “Past water in basement — French drain installed 2022 by XYZ Company” is better than checking “yes” with no explanation.
• Keep receipts. Attach repair invoices, contractor letters, and inspection reports to the disclosure. This shows good faith and reduces buyer anxiety.
• Don’t guess. If you genuinely don’t know, mark “unknown.” But don’t use “unknown” as a way to avoid disclosing something you actually know about.
• “As-is” doesn’t eliminate disclosure. Selling your home “as-is” does not exempt you from the disclosure requirement. You still must complete the form honestly. “As-is” only means you’re not agreeing to make repairs — it doesn’t waive the buyer’s right to disclosure.

Agent Responsibilities

Indiana real estate agents have their own disclosure obligations under Indiana Administrative Code 876 IAC 8:

• Listing agents must encourage sellers to complete the disclosure form accurately
• Agents who personally know about material defects must disclose them, even if the seller doesn’t
• Agents cannot actively conceal defects or mislead buyers
• Buyer’s agents should review the disclosure with their clients and flag any concerns
• Agents are not required to independently inspect the property, but they can’t ignore obvious problems

If you feel an agent has failed to disclose known defects, you can file a complaint with the Indiana Real Estate Commission, which can result in license discipline including fines, suspension, or revocation.

Common Disclosure Disputes in Indiana

The most frequent disclosure disputes in Indiana courts involve:

1. Basement water: The number one dispute category. Sellers who paint over stains, hide cracks, and check “no water problems” despite a history of flooding.
2. Foundation issues: Cracks, bowing walls, and settling that sellers minimize or conceal with cosmetic fixes.
3. Roof leaks: Active or recent leaks that sellers patch without disclosing the underlying problem.
4. Mold: Treated or concealed mold, especially in basements and bathrooms.
5. Unpermitted work: Additions, finished basements, and converted garages built without permits — then marked on the disclosure as “not aware” of any unpermitted work.
6. Sewer and plumbing: Known sewer line problems, recurring clogs, or galvanized pipe deterioration.

If you discover an undisclosed defect after closing, document everything immediately — photos, videos, contractor assessments, and repair estimates. Contact a real estate attorney who handles disclosure disputes. Most offer free initial consultations for these cases. The statute of limitations for fraud in Indiana is six years, but you should act quickly to preserve evidence.

Frequently Asked Questions

Can I sue the seller for not disclosing a problem after I close?

Yes, if you can prove the seller knew about the problem and intentionally failed to disclose it. You’ll need evidence of prior knowledge — repair receipts, contractor testimony, insurance claims, or physical evidence of concealment. A real estate attorney can evaluate your case based on the specifics. Most disclosure lawsuits in Indiana settle out of court once the seller sees the evidence, but some go to trial. Damages typically cover the cost of repair plus attorney fees. The statute of limitations is six years for fraud in Indiana, but starting the process within the first year preserves evidence and strengthens your case.

Does the seller have to fix problems listed on the disclosure?

No. The disclosure is informational — it tells the buyer what the seller knows about the property’s condition. It doesn’t obligate the seller to repair anything. The buyer uses the disclosure (along with their own inspection) to decide whether to proceed with the purchase, negotiate a price reduction, or request repairs. An “as-is” sale doesn’t exempt the seller from disclosing known problems — it just means they’ve stated upfront that they won’t make repairs.

What if the seller provides no disclosure form at all?

If the sale doesn’t qualify for an exemption (foreclosure, estate, etc.), the seller is legally required to provide a disclosure. If they refuse, buyers can rescind the purchase agreement. In practice, if a seller won’t complete the disclosure, treat it as a red flag. Either the seller doesn’t understand their legal obligation (in which case their agent should educate them), or they’re hiding something. Walk away or demand the disclosure before proceeding. Your agent should communicate this clearly through the listing agent.

Are Indiana sellers required to test for radon or mold?

No. Indiana law requires sellers to disclose what they know about radon and mold, but doesn’t require them to test. If the seller has never tested for radon, they can truthfully mark “unknown” on the disclosure. Buyers should order their own radon test ($150-$250) and mold inspection ($300-$600) during the inspection period. In Indiana’s Zone 1 radon classification, skipping a radon test is a risk that could cost you $800-$2,000 in mitigation after closing.

Does an “as-is” sale eliminate disclosure requirements in Indiana?

No. An “as-is” sale means the seller won’t negotiate repairs or credits based on inspection findings. It does not waive the legal obligation to complete a disclosure form honestly. Sellers of “as-is” properties must still disclose all known defects. Buyers of “as-is” properties still receive the disclosure form and can use the information to decide whether the price justifies the known (and potentially unknown) condition issues. Always get an inspection on an “as-is” purchase — you’re accepting the condition, but you still need to know what that condition actually is.
