Concealing a known defect is the most legally dangerous mistake a California home seller can make. Unlike pricing or marketing errors that are bad-but-recoverable, disclosure failures produce civil liability that survives close of escrow by years and can produce damages many multiples of the disclosure-cost the seller was trying to avoid. The math is one-sided: disclosure is always cheaper than concealment.
The legal framework
California Civil Code Section 1102 et seq. requires the Transfer Disclosure Statement. Case law (notably Easton v. Strassburger and related decisions) imposes a broader duty: sellers must disclose all material facts known to them about the property — whether or not the form specifically asks. A material fact is one a reasonable buyer would consider important to their decision. Failure to disclose creates civil liability surviving close of escrow.
The horror story
Composite scenario from patterns Connor has observed:
The seller knew about a slab leak repaired three years prior. Receipts in their kitchen file cabinet. Plumber's invoice clearly described the location and repair. TDS said "no significant defects in plumbing." SPQ didn't mention prior plumbing repairs.
Buyer's inspection found no current leak. Deal closed at $1,150,000.
Eighteen months later, the buyer renovated the affected room. Contractor pulled up tile and discovered the prior repair, including the receipts the seller had left in the kitchen during move-out. The buyer's attorney contacted the original plumber, obtained the work order, and filed legal action within six weeks.
Settlement: $87,000 plus seller's attorney fees. The defect itself, if disclosed at listing, might have produced a $5,000-$8,000 price adjustment. Concealment cost the seller $87,000+.
The categories that most frequently produce lawsuits
- Water intrusion and prior leaks. The single largest category.
- Structural and foundation. Cracks, settling, slab, prior modifications.
- Roof history. Prior leaks, repairs, age beyond expected service life.
- Unpermitted work. Additions, conversions, electrical or plumbing changes without permits.
- Pest and mold history. Prior infestations, remediations, environmental issues.
- Insurance claims. Prior claims the seller didn't disclose.
- Neighbor disputes and easements. Boundary issues, ongoing conflicts.
- Death on property within 3 years. Specific California rules apply.
Why "I forgot" doesn't work
Plaintiffs' attorneys look for evidence the seller actually knew: receipts, invoices, photographs, insurance claim records, neighbor accounts, contractor work orders, inspection reports from prior purchase, email records, HOA records. Discovery reaches all of these. "I forgot" becomes implausible when a paper trail establishes prior knowledge.
Why repaired defects still must be disclosed
Sellers often believe: "We fixed it; it's no longer a problem; we don't need to disclose." This is wrong under California's material-fact standard. The repair itself is the disclosable event. Buyers want to know:
- What was the original problem
- When it occurred
- Who repaired it
- What was done
- What documentation exists
- Whether warranties apply
- Whether the underlying cause was addressed
A properly disclosed repair is generally not a deal-breaker. A concealed repair discovered later almost always becomes one.
The over-disclosure posture
- Review every record: receipts, insurance claims, contractor invoices, prior inspection reports.
- Walk every room with the seller asking "Has anything ever happened in this room? Any leaks, repairs, smells, neighbor noise?"
- Disclose every material fact identified, with documentation where available.
- Use TDS, SPQ, and additional disclosure forms thoroughly.
- Provide pre-listing inspection reports as part of the disclosure package.
- Document the buyer's receipt of every disclosure document.
The financial math
Disclosure scenario
- Disclosure on TDS, SPQ, pre-listing inspection
- Buyer notes the issue, factors into offer
- Possible price adjustment: $0-$8,000 typical (often less than actual defect cost)
- No post-close exposure
- Net cost: $0-$8,000
Concealment scenario
- Defect not disclosed; buyer discovers post-close
- Repair cost: $5,000
- Consequential damages: $5,000-$20,000
- Seller's attorney fees: $20,000-$60,000
- Buyer's attorney fees if awarded: $10,000-$40,000
- Settlement or judgment: $30,000-$150,000+
- Emotional and time cost: 12-24 months of litigation
- Net cost: $40,000-$150,000+
The lesson
Over-disclose. Always. Every known material fact goes onto the TDS, the SPQ, or supplemental disclosure. Every receipt and prior inspection goes into the disclosure package. The seller's protection is the disclosure record.
"Concealment is one of the highest-stakes bets a seller can make, and the odds are terrible. The buyer's contractor pulls up a tile six months after close, finds the prior repair, and the seller is in litigation for a year over a $5,000 issue that would have produced a $2,000 price adjustment if disclosed properly. Disclose everything. Always." — Connor MacIvor
