Can I Sue the Previous Owner for Property Misrepresentation?

Buying a house only to discover it harbours a hidden defect can be infuriating, costly, and even dangerous. After spending months carrying out your due diligence, uncovering a concealed problem often leaves you wanting to sue the seller, but where do you start?

Because property in the UK is sold under the strict legal principle of Caveat Emptor (Buyer Beware), the burden of discovering defects lies primarily with you before contracts are exchanged. However, if you were actively misled during the conveyancing process, you may have strong grounds to bring a property misrepresentation or professional negligence claim.

In this article, we examine the most common ways sellers hide property defects, what action you can take after exchanging contracts or moving in, and the legal implications of pursuing a claim.

Lying on the TA6 Property Information Form

During the conveyancing process, the seller must complete a TA6 Property Information form. This is a legally binding document detailing the property's history. Within the document, it states:

If the seller provides false answers here, it is a clear-cut case of misrepresentation. Common TA6 disputes include:

• Neighbour Disputes: Denying any history of disputes or complaints with neighbours, when police, council records, or solicitor letters prove otherwise. These can include blocked driveways, noise complaints, and even disputes over pruning a tree.
• Flooding & Subsidence: Falsely claiming the property has never suffered from flooding or structural subsidence to avoid deterring buyers or triggering mortgage retentions.
• Boundaries: Misrepresenting who owns and maintains specific boundary walls, fences, or hedges, leading to immediate boundary disputes with neighbours upon moving in.
• Japanese Knotweed: Ticking 'No' to the presence of Japanese Knotweed when they knew it was growing on or adjacent to the property, which can severely impact the property's structural integrity and mortgageability.

Actively hiding physical property defects

While a seller does not have to point out obvious defects, they are legally prohibited from actively concealing them to deceive a surveyor or buyer. Under English law, if you can prove the seller took deliberate steps to mask a serious issue, it is treated as a false statement of fact under the Misrepresentation Act 1967, and you can sue for the cost of repairs. Examples of actionable concealment include:

• Erecting false stud walls, heavy panelling, or large fitted furniture specifically to hide severe, active damp or structural cracking.
• Painting over extensive black mould or water damage just days before a viewing, without resolving the underlying leak or roof defect.
• Laying fresh turf, gravel, or decking explicitly to cover up invasive Japanese Knotweed, sinkholes, or a collapsing drainage system.

Missing building regulations and compliance

Unregulated building work, such as a structural wall removal, an extension without sign-off, or a loft conversion that fails fire safety regulations, is a major legal and financial liability. If the seller explicitly stated on the TA6 Property Information Form or in response to conveyancing legal enquiries that all structural alterations had full building control approval when they did not, you have clear grounds to sue them for misrepresentation.

Under Section 36 of the Building Act 1984, the local authority has statutory powers to enforce compliance, and can even apply for a court injunction requiring unauthorised work to be altered or demolished. If you discover dangerous or uncertified work after completion, you must instruct an independent structural engineer immediately to inspect load-bearing elements, assess whether the work complies with Part A (Structure), and determine if the building is at risk of movement or collapse.

Depending on the engineer's findings, you may need to apply to the local council for a Letter of Regularisation. This requires council inspectors to carry out intrusive inspections, often exposing concealed joists and steel beams, and will mandate costly remedial construction works before sign-off is granted. If the seller knowingly misled you regarding certification, the full cost of these structural repairs, professional fees, and any resulting loss in property value will form the foundation of your legal claim.

Who is at fault? (Surveyors, Solicitors & Agents)

If the seller did not actively lie, but a major issue was still missed before exchange of contracts, you may have a professional negligence claim against the experts you hired to protect you:

• Your Conveyancing Solicitor: If your solicitor failed to carry out the necessary local authority searches, ignored missing paperwork for an obvious extension, or failed to raise standard legal enquiries regarding clear title defects, they may have breached their professional duty of care.
• Your RICS Surveyor: Surveyors conduct non-intrusive inspections, meaning they cannot be blamed for cleverly hidden defects beneath floorboards. However, if there is a visibly load-bearing wall missing or an obvious, severe subsidence that they completely failed to flag in your Level 2 or Level 3 report, you may have grounds to sue your surveyor for negligence.
• The Estate Agent: Under the Consumer Protection from Unfair Trading Regulations (CPRs) and The Property Ombudsman (TPO) Code of Practice, estate agents have a strict legal duty to provide accurate property descriptions and disclose all material information that a buyer needs to make an informed decision. If the agent was aware of a severe physical defect, an ongoing neighbour dispute, or missing building regulations, but deliberately withheld or misrepresented this information to secure the sale, they have breached consumer protection laws. You can escalate a formal complaint to the Ombudsman for compensation, or pursue a legal claim against the agency directly for your financial losses.

The risks of ignoring hidden defects

Whether you are dealing with a severe physical defect, toxic neighbour disputes, or unregulated building work, failing to resolve the issue promptly carries significant consequences for your property investment:

• Critical Risk (Safety & Prosecution): Unregulated building work can be structurally unsafe or present a severe fire hazard. If the property is dangerous and you let it to tenants who are subsequently injured, you face criminal prosecution and substantial fines.
• High Risk (Unmortgageable & Unsaleable): Mortgage lenders will refuse to lend against a property with severe structural defects, missing regulations, or active boundary disputes. This renders your home completely unsaleable to anyone other than a cash buyer seeking a heavy discount.
• Moderate Risk (Financial Loss): Even if the property is safe, unresolved disputes or minor unapproved alterations will severely devalue the property on the open market, and you will have to fund the legal dispute resolutions or structural remedies out of your own pocket.

How to sue the previous owner

If you believe you were actively misled on the TA6 form, or that physical defects were deliberately hidden, you need to immediately evidence the issue:

• Take clear, date-stamped photographs of the defect using your mobile phone.
• Record a video of the issue, particularly if it involves an active water leak or moving structural damage.
• Locate and safely store a copy of the seller's original TA6 Property Information Form and any written assurances provided by the estate agent.

As soon as you have gathered your evidence, you have a strict legal duty to mitigate your losses by preventing any further damage to the property. This may mean calling an emergency plumber to stop a leak or an electrician to isolate a dangerous circuit.

Crucially, you must prioritise making the area safe. If the defect poses an immediate threat to life, such as a severe gas leak or a major structural collapse, you must leave the premises and avoid returning to the property until emergency professionals have declared it safe.

Once the immediate danger is resolved and your evidence is compiled, the first legal step is to instruct a property litigation solicitor to write a formal Letter of Claim to the previous owner. This document must clearly outline your legal position, evidence of misrepresentation, and the exact financial damages you seek to recover.

Should I repair the issue?

Yes. Under English law, you have a strict legal duty to "mitigate your loss". This means you are expected to take reasonable steps to prevent the problem from worsening and to carry out necessary repairs. You cannot simply ignore a hidden roof leak that will destroy the rest of the house and then expect the seller to pay for the resulting devastation.

However, the courts will only allow you to claim for reasonable repair costs. You must not use the dispute as an excuse to upgrade the property or overspend. If a seller's misrepresentation concealed a damaged standard kitchen, and you choose to replace it with a luxury bespoke design, the court will only order the seller to cover the cost of a like-for-like standard replacement.

Crucially, before you instruct builders to begin permanent repairs, you must ensure you have fully documented the damage. It is highly recommended that you obtain an independent expert report, such as from a RICS surveyor or structural engineer, alongside at least three written quotes from independent contractors. This provides your litigation solicitor with the hard evidence needed to prove to the court that the repairs were strictly necessary and that the financial damages you are claiming are fair and competitive.

Should I instruct a solicitor?

Property litigation is notoriously complex. For high-value structural defects, instructing a specialist property dispute solicitor is essential to assess the legal merits of your case and draft a robust Letter of Claim. However, you must carefully weigh the cost of the repair against your potential legal fees.

If the financial loss to fix the issue is minor, such as a £500 plumbing repair, instructing a solicitor is rarely commercially viable. In England and Wales, civil disputes valued at less than £10,000 are allocated to the Small Claims Track. In a small claim court, even if you win your case and prove the seller lied, you generally cannot recover your legal costs from the losing party.

This means your solicitor's hourly rates could easily wipe out the compensation you receive. While a seller's actions might have caused you severe stress and financial loss, for low-value disputes under £10,000, you are often better off negotiating directly with the seller or filing a claim yourself using the government's online Money Claim service.
