The Legal Foundation: 'Caveat Emptor' in UK Property Law
In England and Wales, residential property acquisitions are governed by the ancient legal principle of Caveat Emptor—Latin for 'let the buyer beware'.
Under Section 52 of the Law of Property Act 1925 and established common law, a seller has no implied obligation to ensure the property is fit for habitation, free from structural defects, or protected from environmental hazards. The entire burden of investigating the physical condition, legal title, boundary rights, and planning history rests squarely upon the purchaser.

What the Seller Must Disclose: The Law Society TA6 Form
While the seller does not pay for physical surveys or searches, they are legally bound to answer formal enquiries truthfully on the Law Society Property Information Form (TA6) and Fittings & Contents Form (TA10).
The TA6 form legally compels the seller to disclose known boundary disputes, notices from neighbours, flooding history, planning applications, Japanese knotweed presence, and building alterations.
If a seller knowingly conceals a defect or provides false information on Form TA6, the buyer can sue for fraudulent misrepresentation under the Misrepresentation Act 1967 post-completion, seeking substantial compensation or rescission of the contract.
A seller is only required to disclose defects they personally know about. If an underground drain is collapsed or roof timbers have dry rot that the seller was unaware of, they bear zero legal liability. This is why the buyer must pay for independent surveys.
Can Buyers Ask Sellers to Pay for Due Diligence Defect Repairs?
When a buyer's due diligence uncovers defects (such as damp, missing planning certificates, or electrical rewiring needs), the buyer cannot legally compel the seller to fix them.
However, the buyer has complete commercial leverage: until contracts are exchanged, the buyer can make price reduction demands, request that the seller pays for legal indemnity policies, or walk away completely.
