Boundary disputes explained: the complete homeowner’s guide

A plain-English guide to boundaries for homeowners — how they are determined, the common flashpoints over fences and trees, and how to resolve disputes. The recurring theme: boundary disputes are evidence disputes.

Does the Land Registry show the exact boundary?

No. Land Registry title plans show “general boundaries” only — they are based on Ordnance Survey mapping and are not an exact record of the legal line. Many disputes start from the wrong assumption that they are.

How do I find the exact boundary of my property?

There is rarely one definitive answer. The exact boundary is usually established by weighing several pieces of evidence together — title plans, deeds, historic documents, physical features and what is found on site.

What is the difference between a legal boundary and a physical boundary?

The legal boundary is the invisible line that divides ownership; the physical boundary is the fence, wall or hedge you can see. They do not always coincide — which is why assumptions based on the fence line can mislead.

What does a boundary surveyor actually do?

A boundary surveyor inspects the site, measures it, interprets the documentary and physical evidence, and reports objectively. The role is to assess the evidence impartially — not simply to support one party’s opinion.

What evidence is used to determine a boundary?

Historic conveyances, title plans, surveys, photographs, witness evidence and physical inspection are all used. No single piece is always decisive — the strength lies in the evidence as a whole.

What is a boundary agreement?

A boundary agreement is a written agreement between neighbours recording where they accept the boundary lies, or who maintains what. Reaching agreement early is often quicker and far less expensive than litigation.

What is a determined boundary?

A determined boundary is an exact line formally fixed and recorded by HM Land Registry, replacing the usual “general boundary”. It normally follows careful evidence analysis rather than assumption.

Can I replace my fence without my neighbour’s permission?

If the fence is yours, you can usually replace it — but only on the same line, without trespassing onto your neighbour’s land, and within height limits. Replacing a fence without first understanding ownership can create a dispute.

Can my neighbour attach things to my fence?

If the fence is yours, your neighbour has no automatic right to attach trellis, plants or anything else to it without your consent. The answer depends on who owns the fence and the surrounding circumstances.

Can my neighbour move the fence?

Not onto your land. But whether a fence has actually been moved — and where it should sit — is itself an evidence question, so the first step is to establish the facts rather than assume encroachment.

Party fence walls on the boundary

When a wall standing on the boundary line is shared between neighbours.

Who is responsible for maintaining a boundary fence or wall?

Owning a boundary fence or wall does not, by itself, create a legal duty to maintain it. A duty usually arises only where the deeds impose one, or where another rule — such as support or safety — applies.

Who owns the fence between two properties?

There is no general rule that the left- or right-hand fence is “yours”. Fence ownership is established from the deeds, any T-marks on the plans and historical evidence — and is often uncertain, so it should not be assumed.

Trees & hedges

Can I cut overhanging branches?

You generally have a right to cut branches that overhang your boundary back to the line — but the right is not unlimited. You cannot trespass to do it, the cuttings remain your neighbour’s, and protected trees need consent.

Trees & hedges

What happens if tree roots damage my property?

A tree owner can be liable if their roots damage your property and the damage was foreseeable. But liability is not automatic — establishing the cause usually requires expert evidence.

Basement extensions and encroachment

How below-ground works can encroach across a boundary line.

Building a wall on or across the boundary

Your rights, and your neighbour’s, when a new wall meets the boundary line.

Can my neighbour build on the boundary line?

It depends on what they are building and where the line truly lies. A neighbour may build up to the boundary, and in some cases on it under the Party Wall Act — but planning, ownership and trespass all apply at once, so the laws overlap.

Agreeing to build on the boundary line

Reaching agreement with a neighbour before building up to or across the line.

My neighbour has built on my land – what should I do?

First establish the facts. Whether something has actually been built over the boundary — and where the boundary truly lies — is an evidence question. Acting before you understand the evidence can make the dispute harder and more expensive.

My neighbour says my fence is in the wrong place. What should I do?

Don’t argue back — investigate. Whether the fence is actually in the wrong place is an evidence question, so the first step is to preserve evidence and establish the true line calmly, not to confront.

What is encroachment?

Encroachment is where a structure or feature — a shed, garage, extension, wall, eaves or roots — extends over the boundary onto a neighbour’s land. Small encroachments can have significant legal consequences if left unresolved.

Boundary disputes: why court should be the last resort

Boundary disagreements can feel personal, but court should usually be the last resort. Litigation is expensive, slow, uncertain and often damages neighbourly relations permane…

How can I resolve a boundary dispute without going to court?

Most boundary disputes can be narrowed or resolved without court — through direct discussion, an objective expert opinion, mediation, or a boundary agreement. The key is that both sides understand the strengths and weaknesses of the evidence.

How much can boundary disputes cost?

Boundary disputes are often disproportionately expensive. The strip of land in dispute may be worth very little, but the cost of arguing about it can be enormous.
