TA6 Form Explained (2026): What Sellers Must Disclose

One unchecked box on the TA6 form can derail a property sale months after completion — and sellers rarely see it coming.

The TA6 form, formally known as the TA6 Property Information Form, sits at the centre of almost every residential property transaction in England and Wales. Yet it’s also one of the most misunderstood documents in conveyancing. Sellers often rush it. Buyers rely on it heavily. And when disputes arise after completion, the TA6 is frequently where the trail begins.

This guide explains the TA6 form clearly and practically — what it is, why it matters, and how to complete it safely in 2026 without exposing yourself to unnecessary legal risk. You’ll learn which sections cause the most problems, what counts as misrepresentation, and how to answer honestly without guessing, oversharing, or accidentally creating issues that delay your sale.

Unlike generic explanations, this article reflects real conveyancing practice, not theory. It’s written for sellers who want their transaction to proceed smoothly — and stay that way after completion.

What Is a TA6 Form?

The TA6 form is a standardised property disclosure document created by the Law Society and used during residential conveyancing.

It provides buyers with essential transaction information about a property, including:

• Boundaries and access
• Disputes and complaints
• Alterations, planning permissions, and building control
• Utilities and services
• Environmental matters
• Flood risk
• Insurance claims
• Japanese knotweed
• Informal arrangements that affect the property

The TA6 form is used in most residential freehold sales in England and Wales as part of the standard conveyancing process.

Its purpose is simple but important:

To disclose material facts that may affect the property or influence a buyer’s decision to proceed.

Is the TA6 Form Mandatory?

Legally, no. Practically, yes.

No law forces a seller to complete a TA6 form. However, almost all conveyancing solicitors — particularly those following the Law Society Conveyancing Protocol — treat it as mandatory in the transaction pack.

In practice, refusing to complete a TA6 form will usually:

• Delay the transaction
• Raise concerns for the buyer’s solicitor
• Increase follow-up enquiries
• In some cases, it causes buyers to withdraw

Most mortgage lenders also expect the TA6 as part of a standard residential conveyance.

Is the TA6 Form Legally Binding?

The TA6 form is not a contract, but the answers given can be legally relied upon.

If information in the TA6 is incorrect or misleading, a buyer may bring a claim for misrepresentation under the Misrepresentation Act 1967. This can apply even where the seller made an honest mistake.

The key legal principle is:

What matters is whether the buyer relied on the information — not whether the seller intended to mislead.

This is why accuracy matters more than intention.

Who Fills Out the TA6 Property Information Form?

The seller completes the TA6 form.

Your conveyancing solicitor may:

• Explain the questions
• Highlight inconsistencies
• Advice on how to disclose information clearly

But they do not complete the form for you and cannot verify facts you don’t know.

In 2026, many solicitors now use digital TA6 platforms, meaning answers are reviewed and flagged much earlier in the transaction than they were historically. This makes accuracy at the outset even more important.

TA6 and “Material Information” in 2026: Why Timing Now Matters

Since late 2024, sellers have increasingly been encouraged to complete the TA6 form before a property is marketed, not just after a buyer is found.

This reflects the growing emphasis on “material information” under consumer protection regulations. Buyers are now expected to receive key property facts earlier in the process — often before booking viewings.

In practical terms, sellers who prepare the TA6 upfront tend to experience:

• Fewer last-minute enquiries
• Less renegotiation after offer
• Faster progression once a sale is agreed

This doesn’t change the legal status of the TA6, but it does change how early issues are identified — and how easily they can be resolved without derailing a sale.

TA6 Sections That Cause the Most Problems

Disputes and Complaints

This section causes more post-completion issues than almost any other.

You must disclose:

• Formal disputes
• Informal disagreements
• Complaints made to or by neighbours
• Issues involving the local authority or management companies

Even if matters were “minor” or “resolved,” they may still need to be disclosed.

Alterations, Planning Permissions & Building Control

Sellers frequently assume older works “don’t matter anymore.” They often do.

Common problem areas include:

• Extensions
• Loft conversions
• Removed internal walls
• Replacement windows
• Boiler installations

Missing planning permission or building regulations approval often leads to delays or indemnity insurance discussions.

Flood Risk

Flood risk includes more than major flooding events.

You should disclose:

• Known historical flooding
• Surface water issues
• Insurer notifications relating to flood exposure, even if no claim was made

Lenders and insurers treat this information seriously, even where no damage occurred.

Japanese Knotweed

In 2026, guidance is stricter than ever.

You must disclose if the property is affected by Japanese knotweed, which includes:

• Presence within the garden
• Presence within 7 metres of the boundary

Incorrect answers often trigger surveyor rechecks and lender delays.

Informal Arrangements

Verbal agreements still count.

Examples include:

• Shared driveways
• Informal access rights
• Parking arrangements
• Use of neighbouring land

If it affects how the property is used, it should be disclosed.

The Safe Completion Framework (2026)

This is the safest way to complete a TA6 form.

This is usually where sellers pause — unsure whether giving more detail helps or creates problems.

Step 1: Answer Only What You Know

Never guess. If you’re unsure, state “Not known” rather than assuming.

Step 2: Disclose Facts, Not Opinions

Describe what happened, not whether you think it was serious or justified.

Step 3: Attach Evidence Where Possible

Planning permissions, guarantees, insurance correspondence, or certificates reduce follow-up queries.

Step 4: Keep It Updated

Your answers must remain accurate up to exchange of contracts. If something changes, your solicitor should be informed.

Common TA6 Form Mistakes (and Their Consequences)

Pro tip (2026):
If you’ve had work done that required Building Regulations — such as boilers or new windows — start locating Gas Safe, FENSA, or completion certificates early. Missing digital records are now flagged far faster than paper ones ever were.

TA6 vs Other Conveyancing Forms

Each form serves a different purpose, but inconsistencies between them often trigger enquiries.

Real-World Example

A seller answered “No” to the disputes section, believing a neighbour argument was too minor to mention. After completion, the buyer discovered council mediation records.

The court found innocent misrepresentation. The seller was ordered to pay damages — despite having no intention to mislead.

Honesty, not intention, is what protects sellers.
