You can sue your realtor for not disclosing a defect, and buyers bring these claims successfully whenever they can show the agent knew about a problem with the property and stayed quiet. Real estate agents have a legal obligation to tell you about facts that would affect your decision to buy or the price you’d pay, and breaking that obligation exposes them to a claim for your losses. Whether you recover, and how much, depends on what you can prove, how quickly you act, and whether the conduct looks like carelessness or something closer to fraud.
The Duty Your Agent Owed You
Real estate agents owe their clients a fiduciary duty, which means they are legally required to put your interests ahead of their own. That includes loyalty, confidentiality, following your lawful instructions, and telling you everything they know that could affect your decision to buy.
The duty to disclose “material facts” is the cornerstone of any claim. A material fact is anything that could reasonably influence whether you’d buy the property or how much you’d pay. The obligation comes from common law agency principles, state licensing statutes, and professional codes of conduct. The National Association of Realtors’ Code of Ethics requires members to avoid “exaggeration, misrepresentation, or concealment of pertinent facts relating to the property or the transaction.”1National Association of REALTORS. 2026 Code of Ethics and Standards of Practice
Agents are not expected to be structural engineers or environmental scientists. The professional standard asks them to discover and disclose problems that would be “reasonably apparent to someone with expertise in those areas required by their real estate licensing authority.”1National Association of REALTORS. 2026 Code of Ethics and Standards of Practice They don’t have to catch every hidden defect. They absolutely cannot hide the ones they know about.
What Counts as a Defect the Agent Had to Disclose
The obligation covers any known material fact about the property. Structural problems like foundation damage, persistent water intrusion, and roof failures show up in these cases constantly. So do pest infestations, especially termites.
Zoning restrictions, unpermitted construction, and permit violations that could limit how you use or modify the property also have to be disclosed. So do neighborhood conditions a reasonable buyer would want to know about, like nearby industrial noise or ongoing boundary disputes.
The duty focuses on “latent” defects, meaning hidden problems you wouldn’t catch during a normal walkthrough. A cracked foundation concealed behind drywall is latent. A visibly sagging porch is not, because you can see it yourself. And the agent’s duty to disclose what they know exists independently of the seller’s disclosure form. If your agent knows the seller left something off that form, the agent still has to tell you.
Federal Lead-Based Paint Rules
One disclosure requirement is not left to state law. Before you sign a contract to buy any home built before 1978, the seller and agent must disclose any known lead-based paint or lead hazards, provide any available testing reports, and give you a copy of the EPA pamphlet on lead safety.2US Environmental Protection Agency. Real Estate Disclosures About Potential Lead Hazards Anyone who knowingly fails to make the required disclosures is liable for three times the buyer’s actual damages, and that treble-damages provision applies to both the seller and the agent.3Office of the Law Revision Counsel. United States Code Title 42 – 4852d
Whose Agent It Was Matters
If you hired your own buyer’s agent, that agent owes fiduciary duties directly to you. The duty to disclose everything material is at its strongest in that relationship, because the agent is legally your advocate.
The seller’s agent owes fiduciary duties to the seller. That does not mean the seller’s agent can lie to you or hide known defects. In most states, all licensed agents in a transaction have some duty to disclose material facts they know about to all parties, regardless of who they represent. The scope varies by state, but the baseline is consistent: an agent cannot knowingly conceal a material defect from the buyer, even when working for the seller.
Dual agency, where one agent represents both sides, creates inherent conflicts. If you were in a dual-agency arrangement and discover a non-disclosure problem, the conflict itself can strengthen your claim, because the agent had a direct fiduciary obligation to you and couldn’t hide behind the seller’s interests.
What You Have to Prove
Non-disclosure claims against realtors follow a predictable framework with four elements. Weakness in any one of them can sink the case.
- A legal duty existed. This is straightforward if the agent was your buyer’s representative, and it’s usually satisfied against a seller’s agent through the state’s baseline duty to all parties in a transaction.
- The agent knew about the problem. This is where most claims either succeed or fall apart. Emails, text messages, inspection notes, prior listing descriptions, and testimony from contractors or other agents who discussed the issue can all establish knowledge.
- The agent failed to disclose it. Silence counts, and so does downplaying. If the agent mentioned an issue but described it inaccurately, that can qualify as failing to disclose the material fact.
- You suffered financial harm because of it. There has to be a direct connection between the non-disclosure and your monetary loss. Spending $30,000 to repair a hidden foundation problem makes that link clear. If the undisclosed fact wouldn’t have changed your decision or didn’t reduce the property’s value, damages become hard to prove.
Actual Knowledge vs. Constructive Knowledge
The knowledge element is the most contested. “Actual knowledge” means the agent personally knew about the defect, perhaps because they saw a prior inspection report, heard the seller discuss it, or observed the problem firsthand.
“Constructive knowledge” is a broader standard some states apply. Under that theory, an agent is liable for defects they should have discovered through reasonable diligence, even if they claim ignorance. If the basement had visible water staining during the agent’s walkthrough and the agent never raised moisture with you, a court could find the agent should have known and should have said so. Whether your state applies only actual knowledge, or also constructive knowledge, changes the strength of your claim significantly.
Whether an “As-Is” Clause or Home Inspection Ends Your Case
Sellers sometimes insist on “as-is” language in the purchase contract, and buyers often wonder whether that clause protects the agent. It does not, at least not against fraud or intentional concealment. An as-is clause may limit the seller’s obligation to make repairs, but it does not authorize anyone to hide known defects. Courts consistently hold that fraud overrides as-is language, because you can’t contractually waive the right not to be deceived.
A home inspection creates a different question. If your inspector missed the same defect the agent concealed, the agent may argue you had the chance to discover the problem yourself. That argument has limits. A home inspection is a general visual review, not an exhaustive forensic examination, and agents cannot hide behind an inspector’s failure to catch something the agent already knew about. However, if the defect was something a competent inspection should have flagged and you waived the inspection contingency, that decision can weaken your claim.
What You Can Recover
The financial recovery in a successful non-disclosure claim depends on the severity of the defect, the nature of the agent’s conduct, and the remedies your state allows.
Compensatory Damages
Compensatory damages cover your actual financial losses. The most common measure is the cost of repairing the undisclosed defect. If the defect can’t be fully fixed, courts may instead award the difference between what you paid and what the property was actually worth at the time of sale with the defect factored in. Depending on the jurisdiction, you may also recover out-of-pocket costs tied to the non-disclosure, such as temporary housing during major repairs or expenses related to health hazards like mold remediation.
Punitive Damages
When the agent’s conduct crosses from negligence into intentional fraud or reckless disregard for your rights, courts may add punitive damages on top of compensatory damages. Punitive damages exist to punish bad behavior and discourage other agents from doing the same. Most states require clear and convincing evidence of intentional misconduct or gross negligence before allowing them. They’re uncommon in ordinary non-disclosure cases but can be substantial where the agent actively participated in concealing a serious defect.
Rescission
In cases involving significant fraud, some buyers pursue rescission, which unwinds the sale. You return the property, the seller returns your purchase price, and both parties are put back where they started. Courts don’t grant rescission lightly, but when an agent and seller conspired to hide a defect so severe no reasonable buyer would have gone through with the purchase, it becomes a viable option.
Lead-Based Paint Violations
Federal lead disclosure violations carry a unique penalty. A knowing violation triggers treble damages, meaning three times your actual losses.3Office of the Law Revision Counsel. United States Code Title 42 – 4852d Spend $15,000 remediating lead paint that was never disclosed in a pre-1978 home and you could recover $45,000. That makes lead disclosure claims among the most financially significant non-disclosure actions a buyer can bring. The EPA also imposes separate civil penalties that can reach into the tens of thousands of dollars per violation.
How Long You Have to Sue
Every state sets a statute of limitations for non-disclosure and fraud claims, and missing yours means losing the right to sue regardless of how strong the case is. These deadlines typically range from two to six years depending on the state and the legal theory. Fraud claims and breach of fiduciary duty claims may carry different deadlines even within the same state, so the way your attorney frames the case matters.
The critical wrinkle is the “discovery rule,” which most states apply to real estate defect claims. Under that rule, the clock doesn’t start when you close on the house. It starts when you discover the defect, or when you reasonably should have discovered it. If a hidden plumbing problem doesn’t surface until three years after closing, the limitations period begins when the first signs appeared, not on closing day.
Don’t treat the discovery rule as permission to wait. Once you spot the problem, the clock is running, and even identifying the right deadline requires legal analysis of your state’s specific rules.
What to Do Right Now if You Just Discovered a Defect
What you do in the first few weeks after discovering an undisclosed problem can decide the case.
- Document everything immediately. Take detailed photos and video of the defect. Note the date you first noticed it and what brought it to your attention. Save every communication you’ve had with your agent, including texts, emails, and notes from phone calls.
- Get a professional assessment. Hire a qualified contractor, engineer, or specialist to evaluate the defect. You need someone who can confirm the problem, estimate when it likely originated, and give an opinion on whether it should have been known before the sale. Their report becomes key evidence.
- Review your transaction documents. Pull the seller’s disclosure form, the purchase agreement, any inspection reports, and communications from your agent. Look for what was and wasn’t disclosed. Check whether your contract contains an attorney’s fees provision, which could affect what you recover.
- Send a written demand. Before filing suit, most attorneys will send a formal demand letter to the agent and their brokerage describing the undisclosed defect, outlining your damages, and giving the other side a deadline to respond. Many disputes settle at this stage, especially when the evidence is strong.
- Consult a real estate attorney. Non-disclosure claims involve overlapping state laws, professional standards, and potential insurance coverage. An experienced attorney can evaluate which legal theories apply, estimate potential recovery, and advise whether the claim justifies the cost of litigation.
Two Things That Often Change the Outcome
Filing a Licensing Board Complaint
A lawsuit isn’t your only option, and it isn’t always necessary to get results. Every state has a real estate commission or licensing board that oversees agent conduct. A complaint won’t get you direct compensation, but it can trigger a formal investigation. If the board finds the agent violated disclosure requirements, it can impose fines, mandatory education, license suspension, or license revocation.
A licensing complaint creates an official record of the misconduct, which can support a later civil claim. It puts pressure on the agent and brokerage to settle. And it doesn’t require you to hire an attorney or pay court costs. You can file a licensing complaint and pursue a civil claim at the same time, since the two are independent proceedings.
Errors and Omissions Insurance
Most real estate agents carry errors and omissions insurance, a form of professional liability coverage. When a buyer files a non-disclosure claim, the agent’s E&O policy typically covers legal defense costs and any settlement or judgment up to the policy limit. That’s good news for buyers, because there’s usually an insurance company with real money behind the claim rather than just the agent’s personal assets.
In practice, claims are handled by the insurer’s attorneys, and settlement talks happen with a professional claims adjuster. Insurance companies settle meritorious claims routinely because it’s cheaper than going to trial. If you have solid evidence of knowledge and non-disclosure, the presence of E&O coverage makes a reasonable settlement more likely. E&O policies typically exclude intentional fraud, though, so if the conduct was deliberately deceptive rather than negligent, the insurer may deny coverage and the agent becomes personally responsible for any judgment.
