If you’re selling a home in the United States, seller disclosures generally mean two things: a federal lead-based paint disclosure for any home built before 1978, and, in nearly every state, a written form telling the buyer about material defects you actually know about. The specifics vary by state, but the core duty is consistent. Tell the truth about what you know, in writing, before the buyer is contractually bound.
The Federal Lead-Based Paint Rule
The Residential Lead-Based Paint Hazard Reduction Act of 1992 is the only federal disclosure law that reaches most home sellers directly. If your home was built before 1978, four things have to happen before the buyer is contractually obligated to purchase.1Office of the Law Revision Counsel. 42 USC 4852d – Disclosure of Information Concerning Lead Upon Transfer of Residential Property
- Give the buyer the EPA pamphlet “Protect Your Family from Lead in Your Home.”2U.S. Environmental Protection Agency. Protect Your Family from Lead in Your Home (English)
- Disclose any known lead-based paint or lead hazards, and hand over any reports or records you have.
- Give the buyer a 10-day window to test for lead paint before the contract becomes binding. The buyer can agree in writing to a different period or waive the testing opportunity.3U.S. Department of Housing and Urban Development. Guidance on the Homebuyer’s Option to Test for Lead-Based Paint
- Include a specific Lead Warning Statement in the purchase contract, with the buyer’s signed acknowledgment that they received the pamphlet and had the chance to test.
The penalties are serious. The statute sets a base cap of $10,000 per violation, raised above that figure by federal inflation adjustments. A seller who knowingly violates the rule is jointly and severally liable for three times the buyer’s actual damages, plus court costs, attorney fees, and expert witness fees.4eCFR. 24 CFR Part 35 – Lead-Based Paint Poisoning Prevention in Certain Residential Structures “Knowingly” matters. If a lead inspection report sat in your filing cabinet and you didn’t hand it over, courts are unlikely to accept that you forgot.
Lead paint is the only hazard that triggers a federal seller duty. Flood zones, environmental contamination, and natural hazards are handled by state law. Lenders with federally backed loans must notify borrowers about flood insurance in Special Flood Hazard Areas, but that sits with the lender, not the seller.5FEMA.

What State Disclosure Forms Cover
Nearly every state requires a written seller disclosure form, usually supplied by the state real estate commission or your agent. These forms focus on material defects, meaning problems serious enough to affect the home’s value or the safety of people living in it. A slow-draining sink probably isn’t material. A cracked foundation or a chronically leaking roof almost certainly is.
Expect the form to walk through the property system by system:
- Structural issues such as foundation settling and water intrusion in basements or crawl spaces
- Roof condition and age
- Plumbing and electrical systems
- HVAC, the water heater, and major appliances
- Pest infestations, including termites
- Environmental hazards such as radon or mold
- Septic system status, well water quality, and underground storage tanks, where those exist
- Boundary disputes, easements, zoning concerns, and nearby noise sources
- HOA membership, fees, and any pending special assessments
The governing standard across almost all these states is actual knowledge. You disclose defects you know about, including problems hidden behind drywall or under the slab. You don’t have to hire an inspector to go hunting for defects you’ve never noticed. But you can’t pretend not to know about a basement that floods every spring because no one asked. Courts distinguish between genuinely not knowing and choosing not to look.
Stigmatized Properties
Some states address what the industry calls stigmatized properties: homes affected by events that didn’t physically damage the structure but might affect a buyer’s willingness to purchase, such as a death on the premises or alleged paranormal activity. The rules are not uniform. Some states require disclosure of violent deaths within a defined window, some say sellers don’t have to volunteer the information unless directly asked, and some are silent. If this applies to your property, check your state’s specific rule.
Caveat Emptor States
A small number of states still follow some version of “buyer beware,” with limited or no formal disclosure form. Even there, a seller who actively lies about a known defect or takes steps to conceal one can face fraud claims. The absence of a form is not a license to deceive. The federal lead paint rule still applies in these states to any pre-1978 home.
When You May Be Exempt From the State Form
Even in states with robust disclosure laws, several transfer types are commonly exempt because the seller has no firsthand knowledge of the property:
- Foreclosure sales by banks or lenders
- Estate sales handled by a personal representative or executor
- Court-ordered sales arising from divorce, bankruptcy, or similar proceedings
- Transfers between family members, including spouses and parent-child transfers
- New construction sold by the builder for the first time, though builders carry their own warranty duties
These exemptions vary from state to state. And none of them exempts a pre-1978 home from the federal lead paint disclosure.
“As-Is” Does Not Replace Disclosure
One of the most common misconceptions in residential real estate is that listing a home as-is means you can skip the disclosure form. It doesn’t. An as-is clause tells the buyer you won’t make repairs before closing. It says nothing about your duty to tell the truth about what you know.
Selling as-is and disclosing known defects are two separate obligations. You can sell a home as-is and still tell the buyer the furnace is 25 years old and the basement gets damp in spring. Courts in most states have held that fraud claims survive an as-is clause when a seller knew about a serious defect and said nothing.
Filling the Form Out Well
Before you sit down with the form, gather your records: roof age, HVAC servicing dates, any history of water intrusion, receipts for major repairs like foundation work or electrical panel upgrades, and reports from previous inspections. Be specific when describing a known issue. “Roof leaked around the chimney flashing in March 2022; repaired by ABC Roofing for $1,800” protects you far better than “roof had a minor issue.”
If you genuinely don’t know the answer to a question, mark it “unknown” rather than guessing. An honest “unknown” creates no legal exposure. An incorrect “no” creates a lot of it.
Don’t overlook the questions about conditions outside the home. HOA membership, fee structure, pending special assessments, boundary disputes, easements, and nearby environmental hazards all belong on the form if you know about them. Attach copies of contractor receipts where relevant; documentation from licensed contractors is strong evidence that work was done properly and to code.
Updating the Disclosure Before Closing
The disclosure isn’t a one-time document. If something changes between the day you sign it and the day you close, you generally have to tell the buyer. A pipe that bursts during escrow, a termite discovery, or a neighbor filing a boundary dispute all qualify.
Many states give the buyer a specific window to cancel the contract after receiving an amended disclosure, often three to five days depending on how the update is delivered. The buyer agreed to buy based on what you originally told them, so if the facts change materially, they get the chance to reconsider.
Sellers sometimes hesitate to amend because they’re afraid it will kill the deal. Amending a disclosure protects you from a post-closing lawsuit, which is far more expensive than a renegotiation during escrow.
When to Deliver It
In most states, you must deliver the completed disclosure before the buyer signs a binding purchase contract. Some sellers make the form available as early as the first showing to filter out buyers uncomfortable with the property’s known issues. Timing rules vary, and some states allow delivery within a set number of days after an offer is accepted.
Most transactions now handle delivery through electronic platforms that create a timestamped record of when the document was sent and opened. The buyer signs an acknowledgment confirming receipt. That signed acknowledgment is your proof you met the disclosure obligation, so confirm it actually gets signed and filed.
What Happens If You Don’t Disclose
A buyer who finds an undisclosed material defect after closing has several possible claims. Fraudulent misrepresentation applies when a seller actively lied or concealed a known problem. Negligent misrepresentation covers situations where the seller should have known about a defect based on obvious signs. Breach of contract applies when inaccurate statements on the disclosure form were incorporated into the purchase agreement.
Courts routinely award compensatory damages for the cost to repair the undisclosed defect, and some states allow punitive damages when concealment was intentional. For lead paint specifically, the federal treble-damages provision means a knowing violation can cost you three times the buyer’s losses, plus their legal fees.1Office of the Law Revision Counsel. 42 USC 4852d – Disclosure of Information Concerning Lead Upon Transfer of Residential Property Disclosure failures are the single most common source of claims against sellers and their agents in residential transactions, and defense costs alone can be substantial even when the seller eventually wins.
