How to Sell a House with a Boundary Dispute

Boundary disputes are one of the most stubborn problems a seller can face, and they have a habit of surfacing at the worst possible moment - usually just as a buyer's solicitor starts digging into the paperwork.

However, a dispute over a fence line or a few inches of garden doesn't have to sink your sale. You can absolutely sell a house with a boundary dispute and the trick is knowing how to handle it so it doesn't take unnecessary time or cost you a fortune to put right.

In this blog, we explain what a boundary dispute is, whether you have to declare it, how it affects your sale, and how to sell your house without the arguments.

What is a boundary dispute?

Boundary disputes are a disagreement between neighbours over where the legal dividing line between their two properties actually sits. Under the General Boundaries Rule, the boundaries shown on your Land Registry title plan are "general boundaries" only - they're indicative and accurate to within around half a metre, not a precise line you can measure to the centimetre.

That gap between what's on paper and what's on the ground is where most boundary disputes with neighbours begin. Boundary disputes can occur from:

• Fence and wall positions, where one neighbour replaces a fence a few inches over the line.
• Hedges, trees, and overhanging branches cause disagreements over who owns and maintains them.
• Encroachment when an extension, driveway, or outbuilding strays onto a neighbour's land.
• Shared access and rights of way causes arguments over driveways, paths, or maintenance responsibility.
• Ownership of a boundary feature causes confusion over who is responsible for which fence, wall, or ditch.

Is there a time limit on boundary disputes?

While there's no single deadline, where a neighbour has occupied disputed land for a long period, the rules on adverse possession can come into play, which is another reason these disagreements are best dealt with sooner rather than later.

Do you have to declare a boundary dispute when selling?

Yes, if you know about a boundary dispute, you must declare it and there's no way around it.

When you sell a property in England or Wales, you complete a TA6 Property Information Form. The Law Society's TA6 6th edition became mandatory for all new transactions from 30 March 2026, and boundaries are dealt with right at the front of the form in Section 2. You'll be asked who is responsible for each boundary, whether any boundary features have been moved, and whether a neighbour has breached the boundary.

Crucially, the form asks about any neighbour disputes that have existed at any time, not just active ones, so, even a resolved disagreement needs disclosing. If you're unsure what is a neighbour dispute when selling a house, essentially, it’s an ongoing disagreement between you and a neighbour that results in physical, emotional and financial complications.

Failing to declare a known dispute exposes you to a misrepresentation claim under the Misrepresentation Act 1967 and the buyer could claim compensation, refuse to complete, or even unwind the sale after completion. When in doubt, disclose, and let your conveyancing solicitor help you word it.

How to sell a house with a boundary dispute

So, how do you sell your house with a boundary dispute? Ultimately, you have three realistic routes, and the right one depends on how serious the dispute is, how co-operative your neighbour is, and how quickly you need to move.

Resolve the boundary dispute before you sell

Settling the dispute first puts you in the strongest possible position when you want to sell your house. A property marketed with the boundary clearly agreed and recorded is far more attractive to buyers and lenders alike, and you'll likely achieve a better price.

The cleanest version of this is a determined boundary, where you commission a RICS surveyor's report, and if your neighbour agrees, HM Land Registry records the exact boundary for a £90 application fee.

If you’re wondering how to win a boundary dispute, this option could work successfully if your neighbour co-operates. Where they don't, the costs climb fast. 

Sell on the open market with indemnity insurance

If the dispute can't be fully resolved before you list, but it's relatively contained, you may still be able to sell on the open market with the help of boundary indemnity insurance. This is a one-off policy that protects the buyer and their lender against future financial loss arising from the boundary issue. While it doesn't fix the underlying disagreement, it can give a nervous lender enough comfort to proceed.

This route can work, but it does have limits. Indemnity insurance is usually only available for dormant or low-level disputes, not active rows where the neighbour is actively pressing a claim. You'll also still need to declare the dispute on the TA6 form, so buyers may still try to renegotiate, and you remain exposed to the sale falling through if their solicitor isn't satisfied. It's a useful tool, but it doesn't remove the uncertainty.

Sell to a cash buyer

If you'd rather not gamble on a co-operative neighbour, an obliging lender, or a buyer who doesn't get cold feet, the simplest route is to sell your home to a cash buyer. This way, you don't have to resolve the dispute at all and you sell the property exactly as it stands.

If you’re in this situation, benefits of selling your home to a cash house buyer include:

• No mortgage and no lender's surveyor required, as cash purchase doesn't hinge on a lender's valuation, which removes the biggest issue a boundary dispute creates.
• We buy your home as it is, even with an active boundary dispute. There's no need to commission a determined boundary, settle with your neighbour, take out indemnity insurance, or wait on a tribunal first.
• No renegotiation after disclosure as you declare the dispute, it's factored in upfront, and the offer holds.
• A guaranteed, fast completion, instead of an uncertain timeline and a string of fall-throughs, you get a firm sale on a date that suits you.

What is the average cost of a boundary dispute?

If you choose to resolve your dispute, you’ll need to factor in fees such as boundary dispute surveyor cost and application, which can add up. The table below shows the average costs to expect:

Most solicitors follow the Boundary Disputes Protocol, a structured pre-action process designed to encourage early settlement and keep cases out of court. But if your neighbour digs in, you're into mediation or the First-tier Tribunal, and boundary dispute lawyers don't come cheap.
