Seller Non-Disclosure and Concealment Claims in California Real Estate Litigation

So, you’ve done the walkthroughs, gotten the inspections, and performed your due diligence research, and finally closed on a property. Then, weeks or months later, the nightmare begins: there’s a serious leak, cracked foundation, or some other major problem that nobody mentioned before you bought the property.

That raises the question: did nobody know? Or was the seller aware, and simply didn’t mention it?

That’s the question that leads to most seller-nondisclosure lawsuits in San Diego. Real estate sellers and their legal representatives have a legal duty to share what they know about a property’s condition, including and especially serious defects. If that duty is neglected, buyers may have the right to take legal action. Below, we’re going to walk you through the definition of duty to disclose, how accidental non-disclosure differs from purposeful concealment and fraud, and the process of real estate non-disclosure litigation in California.

California’s Statutory Disclosure Framework: What Sellers Need to Tell You

The basis for most real estate non-disclosure in California is the Transfer Disclosure Statement, required under Civil Code § 1102. State law requires this in the sale of any single-family residential property, as well as for residential resales of properties with up to four residential units. The seller must complete a written statement that discloses known material facts about the property’s condition.

A TDS isn’t a substitute for getting the property inspected, and it doesn’t require the seller to do an inspection to find issues that aren’t already known. However, it does require the seller to be honest about problems they already know about. Even if they are selling the property “as-is,” they still need to fill out the TDS. In an as-is sale, the seller has every right to refuse to fix a known problem, but they do need to tell you, the buyer, that it exists.

This is the same statutory duty we’ve discussed before about fraud in real estate transactions. However, a Civil Code 1102 disclosure violation doesn’t require proving the seller intended to deceive anyone. It just requires that the buyer proves that the seller knew a material fact about the property and did not put it in writing. That’s a much lower bar than fraud, which makes non-disclosure claims easier and quicker to resolve compared to the average full fraud case.

What Counts as a “Material” Defect

It would be absurd to expect a seller to document every single potential flaw in a property, right down to scuffed floorboards and dusty ceiling fans. Minor imperfections don’t trigger liability. A flaw must be considered a “material defect” for it to be grounds for a legal claim.

A material defect is defined by a simple legal test: would a reasonable buyer have considered knowing about that defect important when deciding whether to buy the property, or how much to pay for it?

This also means that defects don’t have to be particularly dramatic, like a crumbling foundation that will send the property sliding into the sea. Instead, the court just wants to know whether the concealed defect is material to the choice to buy the property at a given price.

Material defect non-disclosure claims in California most often involve:

  • Structural issues, including foundation cracks, settling, or inadequate framing
  • Water intrusion, roof leaks, or hidden water damage
  • Unpermitted construction or work that doesn’t meet code
  • Environmental hazards, such as soil contamination, mold, or asbestos
  • Pest or termite infestation
  • Chronic drainage or grading problems
  • Known boundary disputes, encroachments, or undisclosed easements

These issues are reasonably serious and may or may not be visible to the naked eye. While you may have still opted to buy a property with a leaky roof or wiring that’s not up to code, you probably wouldn’t have chosen to buy it at the same price as if it didn’t have those problems. That means those issues are considered material to making your decision to purchase, and you may have grounds for legal action if the seller knew about them but didn’t tell you in writing.

Non-Disclosure vs. Active Concealment: Two Different Claims

Imagine that you purchased a residence with a leaky roof that was not disclosed to you, despite the seller knowing about the problem. There’s a world of difference between the seller forgetting to list the issue, or assuming you knew because you got an inspection, and the seller actively hiding the fact that the roof leaks.

The first case is considered simple non-disclosure. This occurs when a seller fails to mention a known material fact due to negligence, the belief that it wasn’t important, or even a simple clerical error. A claim built on this theory proceeds under Civil Code § 1102 and does not require proving the seller meant to hide anything. The available damages are generally limited to actual losses tied to the defect, like repair costs and the property’s diminished value.

If the seller actually hid facts from you on purpose, that’s active concealment, and it’s an entirely different issue. In this case, the seller took active actions to hide the problem from you, such as by:

  • Painting over water stains
  • Installing new flooring over damaged subfloors
  • Producing falsified documents about repairs the property never received
  • Actively lying on the TDS form

That may be grounds for a seller concealment real estate claim in California, not just a statutory violation. The seller’s conduct shows intent to deceive rather than mere omission.

As a result, concealment claims are eligible for greater damages in many cases under Civil Code § 3294. You could seek punitive damages if you can demonstrate that the defendant acted with “oppression, fraud, or malice.” The definition of fraud in this statute explicitly includes the intentional concealment of a material fact.

As a buyer, this means that the circumstances of a defect’s concealment or lack of disclosure will shape the rest of your case and the value of the damages you may potentially pursue.

Broker and Agent Disclosure Duties

The seller is clearly required to share information with you, the buyer, but they aren’t the only people involved who have disclosure obligations. Civil Code § 2079 states, “It is the duty of a real estate broker or salesperson […] to disclose to [a] prospective buyer all facts materially affecting the value or desirability of the property that an investigation would reveal, if that broker has a written contract with the seller to find or obtain a buyer or is a broker who acts in cooperation with that broker to find and obtain a buyer.”

In other words, licensed real estate agents and brokers are legally obligated to share material facts about the property with buyers if they are trying to make a sale.

There is a little wiggle room here. The law requires them to share information “that [a visual] investigation would reveal,” which is different from the kind of invasive, in-depth investigation that you’d expect from a home inspector. However, if an agent spots or is told about a problem and stays quiet, they may be independently liable, just like the seller.

This is particularly relevant when a seller’s own liability is limited, whether because of a bankruptcy, a trust sale, or a seller who has fallen off the map. A well-documented broker duty claim can preserve a buyer’s ability to recover even when the seller may not be available for a legal claim.

When § 1102 Doesn’t Apply: Commercial Property Non-Disclosure

Civil Code § 1102 is very clearly defined, and has a narrow scope. It only applies to sales of residential property of one to four units. That means it doesn’t apply to:

  • Residential properties with five or more units
  • Office buildings
  • Retail buildings
  • Factories or industrial spaces
  • Commercial real estate as a whole

In short, the law’s statutory disclosure duty only comes into play in a relatively narrow set of residential non-disclosure litigation.

However, commercial real estate sellers may still have disclosure obligations. These requirements are simply imposed by the purchase and sale agreement (PSA) itself, rather than a specific law.

In California, most PSAs include information from the seller, known as a representation or warranty, that explains the property’s current condition, environmental status, lease terms, and known defects. Well-written contracts also include “as-is” clauses that allocates risk for unknown conditions to the buyer. However, if a seller makes false representations in the contract, or otherwise hides known conditions from the seller, the buyer can pursue a breach of contract or fraud claim, depending on the circumstances.

At Peterson Law, we see both residential and commercial non-disclosure claims regularly, and we are prepared to assist you with both. If you buy a commercial property that turns out to have a known structural defect, you’re not out of luck just because § 1102 doesn’t apply. We work with you to build a case that fits your circumstances, whether that means pursuing a statutory violation of § 1102, a breach of contract claim, or fraud.

Buyer’s Rights and Legal Remedies

So, what happens if you do prove that the seller neglected their duty of disclosure, or worse, hid information from you? You have several potential remedies that may be available, depending on your circumstances.

  • Rescission: If you have just purchased the property and discovered an undisclosed defect, rescission effectively undoes the transaction and restores you and the seller to your pre-purchase position. You get your money back, the seller gets the property back, mortgages are undone. This is an excellent solution when available, but it may not be practical if you have already invested money into the property, or if you found out about the problem yourself after selling it to a third party.
  • Compensatory Damages: The most common solution is to receive compensatory damages that cover the cost of repairing the concealed defect, compensating you for the amount you overpaid for the property, and covering any other costs you might have racked up due to the defect. These damages are typically available for both simple non-disclosure and seller concealment.
  • Punitive Damages: If you can prove with clear and convincing evidence that the seller was purposefully defrauding you by hiding the defect, you may be able to pursue punitive damages. These aren’t commonly awarded, but they can be substantial in clearcut cases.

In some cases, you may also be able to pursue damages equal to the cost of litigation. However, some real estate sale contracts include clauses that require the losing party to pay all legal fees, which can be problematic if you do not have a strong case.

Building a Non-Disclosure Case: What Buyers Need

If you want to build a strong case, you need good documentation. If you are preparing to sue a seller for non-disclosure in California, you should collect the following:

  • The original TDS, Seller Property Questionnaire, and any related disclosure forms
  • Pre-sale inspection reports, both the buyer’s own and any the seller may have commissioned and not shared
  • Written communications with the seller or listing agent, including emails and texts
  • Photographs or contractor estimates documenting the defect’s extent and apparent age
  • Expert evaluation establishing when the defect likely arose and whether it would have been apparent to the seller

You also need to act quickly. The statute of limitations for simple nondisclosure in California is three years from the time when you discover the problem. However, claims against real estate agents or brokers have a two-year limitation period that starts when escrow closes and you take possession of the property. If you wait too long, you may lose the opportunity to file a claim at all.

When to Contact an Attorney

If you’re dealing with a problem like a crumbling foundation or faulty commercial property that the seller didn’t tell you about, you could potentially have a legal claim. However, the strength of that claim comes down to documentation and timing. If you suspect the seller failed to disclose this information to you before the sale, the time to talk to an attorney is now.
