What to Do If a Seller Lied on Disclosure
December 6, 2025
By Daniel H. Stoner, Esq.
Purchasing a home is one of the most significant investments most people make in their lifetime. Pennsylvania law expects sellers to provide honest and complete information about the property’s condition to potential buyers.
When a seller lies on the property disclosure form or hides known defects, buyers can suffer financial losses, unexpected repair costs, and emotional stress. A seasoned Pennsylvania construction lawyer can help you hold the seller accountable for the highest possible damages in these cases.
Seller Disclosure Requirements in Pennsylvania
Pennsylvania law requires home sellers to provide a written seller disclosure form before the sale is finalized. This document must identify known defects affecting the property’s condition. The legally required disclosure applies to nearly all residential real property sales.
What Must Be Disclosed
The disclosure statement must include information about known defects and past repairs, including details such as:
- Water damage
- Plumbing issues
- Electrical system failures
- Structural defects
- Roof leaks and sump pump history
- Environmental hazards, such as mold or lead paint
- Pest infestations
- Drainage problems indoors or outdoors
The legal requirement applies to actual knowledge, meaning the seller does not need to guess or test for issues, but they must disclose what they reasonably know.
Good Faith Requirement
Sellers are expected to act in good faith. If a seller knew about defects, concealed them, or intentionally lied on the disclosure form, they can be held responsible for fraud or misrepresentation.
Signs the Seller Lied on the Disclosure
Buyers typically discover defects after closing when problems surface. Indicators that the seller knew about hidden issues may include:
- Evidence of freshly painted patches over water stains
- Recently replaced drywall or flooring in isolated areas
- Covers placed to hide damage during the open house
- Strong odors or air fresheners masking mold or water damage
- Past repair records found in the property
- Comments from neighbors about unresolved problems
These red flags can suggest the seller knew about material defects but failed to disclose them.

Legal Consequences for Sellers Who Hide Defects
Financial Accountability
When a seller lied about the home’s condition, they can be held responsible for repair costs, other costs associated with the defect, and sometimes significant financial penalties. In cases where the deception was intentional and serious, punitive damages may apply to punish the wrongful conduct.
Types of Claims Buyers May File
Buyers may pursue one or more legal claims depending on the facts:
- Fraud or fraudulent misrepresentation
- Breach of contract
- Negligent misrepresentation
- Violations of Pennsylvania real estate disclosure law
Each claim requires proof, and strong legal representation is important to increase the likelihood of a successful outcome.
What to Do If You Discover Undisclosed Defects
Step 1: Gather Evidence
Evidence might include photographs, videos, home inspector evaluations, repair invoices, contractor reports, statements from real estate agents, and copies of the original disclosure statement. Show how the defect contradicts the disclosure form.
Step 2: Contact Qualified Professionals
Hiring reputable professionals, such as a home inspector, mold specialist, roofing contractor, or plumber, can help confirm the scope of the issue and whether the defect existed before the purchase. Such reports can meaningfully strengthen your case.
Step 3: Speak With a Real Estate Attorney
Before confronting the seller, speak with attorneys who practice law with a dedicated focus on real estate transactions and disputes. A legal consultation helps you evaluate your options and determine how to protect your rights without weakening your evidence.
Step 4: Attempt to Resolve the Dispute Informally
Sometimes, the seller will cooperate once confronted with evidence. In some cases, buyers and sellers reach agreements outside of litigation regarding reimbursement for repairs or closing adjustments. However, this approach should always be guided by legal counsel to avoid settlement terms that limit future rights.
Step 5: Consider Legal Action
If informal efforts fail, legal action may be necessary to pursue compensation. A real estate lawyer can help prove that the seller knew about the defect and failed to disclose it. Evidence supporting this may include witness statements, contractor records, repair documents, text messages, emails, or testimony from people familiar with the property.
Compensation You Can Seek From a Seller Who Lied
When a seller lied about the property’s condition, the buyer may seek financial compensation for:
- Cost of repairing undisclosed defects
- Costs of temporary housing during repairs
- Loss in property value
- Legal fees associated with the case
- Monetary damages from fraud
Extreme cases involving intentional deception may qualify for punitive damages.
Preventing Problems Before Closing
Although some defects cannot be detected without access to confidential repair history, buyers can reduce risk by practicing due diligence before signing the purchase contract.
Recommended Steps for Home Buyers
- Hire a qualified home inspector
- Ask detailed questions about past repairs, leaks, or upgrades
- Review the disclosure statement line by line
- Request clarification on suspicious or incomplete answers
- Speak with neighbors when possible to learn about the home’s history
While many homeowners act honestly, due diligence protects you from placing blind trust in the disclosure form.
Seller Lies Can Be Difficult to Detect
Many defects remain hidden behind walls, beneath flooring, or in crawl spaces. A seller who is determined to hide problems may temporarily fix visible damage without correcting the root cause.
Buyers usually rely heavily on the property disclosure statement because it reflects information a home inspector cannot always discover. That is why Pennsylvania law takes seller dishonesty seriously.

Why Hiring a Real Estate Attorney Is Critical
Real estate transactions are legally complex, and proving fraud requires a strategic approach. A real estate attorney helps:
- Analyze evidence to determine whether the seller disclosure violated the law
- Calculate the value of financial losses
- Protect the buyer from settlement traps that limit future claims
- Negotiate aggressively for compensation
- Prepare for litigation if necessary
Working with a legal professional ensures your rights are protected and increases the likelihood of a fair recovery.
