Do You Have to Declare a Neighbour Dispute When Selling?

By Lisa Hayes · 24 August 2026

Yes — in England and Wales you have to declare a neighbour dispute when you sell. The disputes and complaints section of the Law Society's TA6 Property Information Form asks directly about it, and from 30 March 2026 the sixth edition of that form is the only version conveyancers may use. Get it wrong and your buyer can come after you for misrepresentation years after you've moved out.

This is the question sellers agonise over more than almost any other, and understandably so. Nobody wants to write down "we've been at war with number 14 since 2023" and hand it to the person about to give them a quarter of a million pounds. But the alternative — staying quiet and hoping — is a genuinely bad plan, and it's got worse in the last eighteen months.

What actually counts as a "dispute" — and what doesn't?

This is where most sellers talk themselves into trouble. They decide that because nothing went to court, or because they "sorted it in the end", there's nothing to declare. That's not the test.

The test is closer to: would a reasonable buyer want to know about this before committing? If a third party has been involved — the council, the police, a solicitor, an ombudsman, a managing agent, an insurer — you are almost certainly looking at a dispute. If it's been running for months, if there's a paper trail, if it's shaped how you use your own garden, it's a dispute.

Notice the direction of travel in that left-hand column. Complaints made about you count. Sellers routinely leave those off because they consider them unjustified. The form doesn't ask whether the complaint was fair.

Where does a neighbour dispute go on the TA6 form?

It goes in the disputes and complaints section of the TA6 Property Information Form — the form your conveyancer sends you within days of an offer being accepted, alongside the TA10 fittings and contents list. Our full walkthrough of the form is in the 2026 TA6 seller's guide.

The important change for anyone selling this year: the Law Society published a sixth edition of the TA6 in 2025, and from 30 March 2026 it's the only edition conveyancers are meant to use. The form was slimmed to 15 sections — but the disputes question got broader, not narrower. The old wording asked whether there have been any disputes or complaints. The new wording asks whether you are aware of any.

The Law Society's own explanatory notes tell sellers to speak to their solicitor before answering this one. Take that advice. It's the single question on the form most likely to end up in front of a judge.

Do you have to declare a dispute that's already been resolved?

Yes. Past disputes are declarable, and this is where sellers most often come unstuck, because "it's resolved" feels like a complete answer. It isn't.

Look at what happened in McMeekin v Long [2003]. The sellers had a long-running row with a neighbour about parking on a shared access way and rubbish being dumped. Their position was that they'd taken advice, accepted it, and moved on — so, in their view, there was no dispute to declare. They went further and described the neighbours as "good and friendly". The court found a continuous confrontational atmosphere, held it was a fraudulent misrepresentation, and the buyers recovered £67,500 plus costs.

The lesson isn't subtle. "We sorted it out" is your opinion of the situation. The neighbour may have a different view, and the buyer will meet the neighbour long before they meet you again.

If a dispute genuinely was resolved, say so — and say how. "Boundary position disputed in 2022; resolved by a determined boundary application to HM Land Registry, plan attached" is a strong answer. It's a declared dispute and a solved problem in the same sentence.

What if your neighbour started it and you did nothing wrong?

Still declarable. The form is not a court that apportions blame; it's a disclosure exercise. Whether you were the aggressor, the victim or the exasperated bystander makes no difference to whether the buyer gets told.

What it does change is how you frame it. A seller who writes "our neighbour made three noise complaints about us in 2024; the council investigated and took no action, and there have been no complaints since" is disclosing fully and controlling the narrative. A seller who says nothing and lets the buyer hear it over the fence in month two has handed the story to someone else.

Do you have to declare it if you only complained to the council?

Yes — arguably especially then, because there's now a written record with a date on it that any buyer's solicitor could unearth. Statutory nuisance complaints under the Environmental Protection Act 1990 sit on council files. High hedges complaints under Part 8 of the Anti-social Behaviour Act 2003 create a formal case with a fee attached (councils set their own — a few hundred pounds is typical, and some charge considerably more). Anti-social behaviour case reviews leave a trail. Police logs exist even where no action followed.

If you have been the one making complaints, that also tells the buyer something you'd rather they heard from you: the problem is with the neighbour, and it may well continue after you've gone. Hiding it doesn't make it stop. It just means the person who inherits it has a claim against you.

What happens if you don't declare a neighbour dispute?

Short version: the buyer sues you, and they don't have to do it quickly.

Answers on the TA6 are representations the buyer relies on when deciding to exchange. Get one materially wrong and you're exposed under the Misrepresentation Act 1967. Depending on how the court reads your state of mind, that lands in one of three places:

• Innocent misrepresentation — you genuinely believed the answer was true and had reasonable grounds. Damages are discretionary and usually modest.
• Negligent misrepresentation — you had no reasonable grounds for believing it. This is the most common finding against sellers and it carries a real damages bill.
• Fraudulent misrepresentation — you knew, or were reckless as to whether it was true. This is McMeekin territory, and it's where the numbers hurt.

Damages are typically measured by the difference between what the buyer paid and what the property was actually worth with the problem disclosed — plus their legal costs, which in a contested property claim can rival the damages themselves. Rescission (unwinding the sale entirely) is available in principle for fraud, though courts rarely order it once someone has been living in a house for two years.

And the clock is generous to the buyer. Under the Limitation Act 1980 they generally have six years, and where fraud is alleged time can run from when the buyer discovered it. A letter can land on your doormat in 2032 about a form you signed in 2026.

Does your estate agent have to disclose it too?

They do, and the rules changed underneath the whole industry on 6 April 2025.

The Consumer Protection from Unfair Trading Regulations 2008 — the regime that underpinned every "material information" conversation in estate agency for a decade and a half — was replaced by the unfair commercial practices provisions of the Digital Markets, Competition and Consumers Act 2024. The Competition and Markets Authority now has direct enforcement powers, including the ability to fine businesses without going to court first. The National Trading Standards material information guidance was quietly withdrawn as the new regime took over.

The practical effect for you as a seller: agents are asking more, earlier, and writing the answers down. If you tell your agent about a dispute and they list the house without mentioning it, that's their problem as well as yours — but don't count on that as a defence. Tell your agent, in writing, and keep the email. Our guide to material information when selling a house covers what agents now have to publish up front.

How much does a neighbour dispute knock off your house price?

Honest answer: nobody has a reliable national figure, and you should be suspicious of anyone who quotes one to two decimal places. The widely circulated estimates come from estate agent and insurer surveys rather than transaction data. Direct Line research has suggested around 38% of buyers walk away when a dispute is declared; other agency surveys put the value hit somewhere between 5% and 10%. Treat those as mood music, not maths.

What's more useful is understanding which disputes actually move the price:

• Barely registers: a resolved boundary question with a Land Registry plan to prove it. A one-off hedge complaint from four years ago.
• Costs you buyers, not much money: a historic noise complaint with no ongoing issue. You lose the nervous end of the buyer pool and sell to someone more pragmatic.
• Costs you real money: an active, unresolved dispute with a neighbour who still lives there. Expect offers to soften and expect a second round of chipping after the survey.
• Costs you the mainstream market: litigation in progress, an unresolved right-of-way or shared-access dispute, or anything that makes a lender nervous.

If you want a realistic read on your own position before you decide anything, start with a proper valuation of what your house is worth and be candid with whoever's valuing it. A valuation based on a sanitised version of your situation is worth nothing to you.

Will the buyer's mortgage lender care?

Sometimes, and it's the thing sellers forget to plan for.

Lenders lend against the security of the property, and an unresolved dispute that affects access, boundaries or the right to use part of the land can make a valuer add a caveat or a retention. Where litigation is live, some lenders will simply decline until it's concluded. Ongoing anti-social behaviour usually doesn't trouble the lender directly — but it troubles the valuer, and the valuer troubles the lender.

This is how a declared dispute turns into a down valuation weeks after you thought the sale was safe. If your dispute touches title, boundaries or access, get your conveyancer to look at it before you go on the market rather than after you've accepted an offer.

Can indemnity insurance cover a neighbour dispute?

No, and it's worth being blunt because the question comes up constantly.

Indemnity policies cover unknown or unquantifiable legal risks — a missing building regulations certificate, a breach of covenant nobody has enforced, an absent landlord. They work precisely because nothing has happened yet. The moment a dispute is live, or has been raised, or is in correspondence, the risk is known and insurers won't touch it. Applying for a policy while concealing a known dispute is worse than useless: it voids the policy and adds a second misrepresentation to the first.

There is a narrow exception around boundary disputes where a policy may cover the cost of defending a future claim about a boundary that has never actually been challenged. If somebody has already challenged it, that door is closed. See our guide to indemnity insurance when selling a house for where it does and doesn't help.

Should you resolve the dispute before selling, or sell as you are?

There's no universal right answer, but there is a reliable way to decide: ask how long resolution realistically takes, and whether the neighbour is capable of being resolved with.

Here's my view, for what it's worth: sellers dramatically overestimate how much a half-hearted resolution helps them. A mediation you attended reluctantly, that produced a truce nobody believes in, still has to be declared — you've spent six months and a few thousand pounds to change the wording of a disclosure rather than remove it. If the neighbour is the problem and always will be, price it in and go.

How do you actually resolve a neighbour dispute before selling?

In rough order of cost and escalation:

1. Talk, then put it in writing. A short, unemotional letter setting out what you'd like agreed. Keep a copy. Even if it fails, it's evidence you behaved reasonably — which matters if this ends up in front of anyone.
2. Civil mediation. The Civil Mediation Council maintains a register of accredited providers, and a neighbour mediation session typically costs a few hundred pounds each rather than the thousands a solicitor's correspondence will run to. Many councils fund community mediation for free. This is the single most underused option in UK neighbour disputes.
3. Use the specific statutory route, if one fits. High hedges go to the council under Part 8 of the Anti-social Behaviour Act 2003. Persistent noise is a statutory nuisance question for environmental health under the Environmental Protection Act 1990. Repeated anti-social behaviour that's been reported and ignored can trigger an ASB case review.
4. Determine the boundary properly. If the argument is about where the line sits, an application to HM Land Registry for a determined exact boundary, supported by a surveyor's plan, converts an argument into a recorded fact. It isn't cheap and it isn't quick, but it's permanent. Our boundary dispute guide walks through it.
5. Solicitor's letter — last, not first. It escalates, it's expensive, and it creates exactly the paper trail you'll then have to disclose. Sometimes necessary. Rarely the opening move.

Whatever you do, document the ending. A dispute with a written resolution is a manageable disclosure. A dispute that simply went quiet is a question mark, and buyers price question marks pessimistically.

What should you actually write on the form?

Four rules, learned from watching sellers do this badly.

Be factual, not defensive. Dates, what happened, who was involved, how it ended. No adjectives about the neighbour's character. The moment you editorialise, a solicitor reading it starts wondering what else is going on.

Include the resolution. Every declared dispute should end with a sentence about where things stand now. That sentence is what stops a buyer imagining the worst.

Attach the evidence. Council reference numbers, mediation agreements, Land Registry plans, the surveyor's report. Documents reassure. Assertions don't.

Never answer "not so far as I am aware" as a hiding place. That phrase is meant for things you genuinely don't know. Used to dodge something you do know, it's the answer that gets characterised as fraudulent — and it's precisely the pattern the courts have punished.

What if the buyer pulls out when they read it?

Some will. That's the cost of doing this properly, and it's a smaller cost than it feels like at the time.

Realistically, a buyer who withdraws over a declared historic dispute was a buyer who would have withdrawn over the survey, or the lease, or the drains. The disclosure just found them earlier. What you want to avoid is losing a buyer at week ten of conveyancing, because by then you've spent money and lost your place in the market — see our guide on what to do when a chain collapses.

Which is the argument for disclosing early rather than at TA6 stage. If a dispute is significant, tell your agent before listing and let them mention it to serious viewers. You'll get fewer offers and better ones. Sellers hate this advice and are almost always glad they took it.

Can you sell a house with an active, unresolvable dispute?

Yes — but be realistic about which market you're selling into.

The open market with a mortgage buyer works if the dispute is disclosed, historic or contained, and doesn't threaten title, access or lending. It gets difficult when the dispute is live and the neighbour is still there. At that point you're choosing between waiting the neighbour out, dropping the price until someone takes the risk, or selling to a buyer who prices risk for a living.

That last route is what cash house buyers and auction exist for. A genuine cash buyer isn't relying on a valuer's opinion or a lender's appetite, so a declared dispute is a discount rather than a dealbreaker. You will not get full market value — expect a meaningful reduction, and read our explainer on why cash buyers offer below market value before you form expectations. What you get instead is certainty and a completion date, which is worth a great deal when the alternative is eighteen months of viewings and a neighbour who shows up during them.

If your property is at the harder end — active litigation, a contested right of way, a shared access nobody agrees on — our guide to selling an "unsellable" house covers the options in more depth. And if you're weighing up a fast sale against another few months on the open market, selling your house fast sets out the realistic timescales.

Is it different in Scotland and Northern Ireland?

Scotland doesn't use the TA6 at all. Sellers provide a Home Report — a single survey, an energy report and a property questionnaire — and the property questionnaire contains its own question about notices and disputes affecting the property. The duty to be truthful is the same; the paperwork is different, and the point of no return arrives earlier because missives conclude the bargain. Our Scotland seller's guide covers the process.

Northern Ireland uses its own property information form and doesn't operate the Home Report system. The underlying misrepresentation exposure is broadly comparable. See the Northern Ireland guide for the local process.

Does a dispute with a freeholder or management company count?

Yes, and flat owners underestimate this one badly. A service charge you've withheld, a First-tier Tribunal application about a section 20 major works consultation, a running argument with a managing agent about the state of the communal areas — all of it is a dispute affecting the property, and all of it is declarable.

It also tends to surface anyway through the leasehold management pack, which is where withheld service charges and arrears show up in black and white. Declaring it yourself is simply the version where you get to explain it first. If you're selling a flat, our leasehold flat guide covers what the management pack will reveal.

The bottom line

Declaring a neighbour dispute feels like handing your buyer a weapon. It isn't. It's the thing that makes the sale final — because a sale you completed honestly is a sale nobody can unwind in 2032.

The sellers who get hurt aren't the ones with difficult neighbours. They're the ones who convinced themselves that a resolved dispute, or an unfair complaint, or a row that never quite reached a solicitor, didn't count. It counted.

If a dispute has narrowed your options and you'd rather know what a fast, certain sale actually looks like in pounds, it costs nothing to compare offers from vetted buyers and put that number next to the open-market route. Then choose with the full picture in front of you — which is, after all, exactly what you're being asked to give your buyer.
