Seller Disclosure: What Must Be Disclosed and What Happens When It Isn't

A seller disclosure is a formal statement — usually a state-mandated form — where the seller lists everything they know about the condition of the property they're selling. It typically covers the physical structure (roof, foundation, plumbing, electrical), environmental concerns (lead paint, mold, radon, underground storage tanks), legal issues (easements, liens, zoning violations), and sometimes neighborhood conditions (noise, flooding, HOA disputes). Most states require this disclosure to be delivered to the buyer before closing, and many require it before a purchase agreement is even executed. The specific form, timeline, and required categories vary significantly by state — what's mandatory in California isn't necessarily required in Texas. But the underlying principle is the same everywhere: buyers have a right to know what they're buying.

The legal standard in nearly every state is "material defects" — any condition that would significantly affect the property's value or that a reasonable buyer would want to know about before purchasing. This includes: structural problems like foundation cracks, roof damage, or water intrusion; system failures such as a furnace on its last legs or faulty wiring; environmental hazards including mold, asbestos, lead-based paint (federal law for pre-1978 homes), radon, or contaminated well water; and legal or title issues such as encroachments, easements, or unpermitted additions. The "knew or should have known" standard matters here. Sellers can't claim ignorance about a recurring roof leak they've been patching for five years. If they've lived in the home, they're presumed to know its condition. When in doubt, disclose.

Not everything is a required disclosure. Most states carve out exceptions for facts that are publicly available — a buyer can look up flood zone maps, tax records, or building permits themselves. Many states also have specific exemptions around stigmatized properties: a home where a death occurred, a nearby registered sex offender, or a property that was the scene of a crime generally does not need to be disclosed in most jurisdictions (though some states require it for certain violent deaths). Sellers are also typically not required to disclose conditions they're unaware of — the key distinction is between what they know and what they reasonably should have known. Agents should be familiar with their state's specific carve-outs, because guessing wrong can expose both the seller and the agent to liability.

This is where deals come undone — sometimes years after closing. If a buyer discovers after closing that the seller knew about a material defect and failed to disclose it, they can sue for fraud, misrepresentation, or breach of contract. Remedies range from damages (the cost to fix the defect) to rescission of the sale. The statute of limitations varies by state but is often several years — meaning a seller can face a lawsuit long after they've moved on. What makes this worse for agents: in most states, listing agents who knew or should have known about an undisclosed defect can be named in the lawsuit too. The agent's duty is to disclose facts that materially affect the value of the property if they know about them — even if the seller doesn't want them disclosed.

Sellers sometimes push back on disclosure. "We don't want to scare buyers." "It's minor." "We're selling as-is anyway." This is where agents earn their commission — not by finding buyers, but by protecting their client from a lawsuit three years after closing. Your job is to walk the seller through the disclosure form line by line, flag anything that should be included, and document that you did. If a seller refuses to disclose a known defect, you have an obligation to consider whether you can continue representing them. Many agents don't realize they have independent disclosure duties — it's not enough to say "I told my seller to disclose it." As a buyer's agent, your role is different but equally important: make sure your client has received the disclosure, reads it carefully, and uses the inspection period to verify anything that seems concerning.
