Dealing with a neighbour boundary dispute? Understand boundary law, the role of title deeds, and practical options for resolving disputes in the UK.
Last reviewed: 30 March 2026
Quick answer
Boundary disputes between neighbours in England and Wales are governed by a combination of property law, the Land Registration Act 2002, and common law principles. The exact position of a boundary is determined by the title deeds rather than the Land Registry's title plan, which shows only general boundaries. Resolving boundary disputes early and proportionately is often important, as legal costs can escalate significantly.
What this means in practice
Establishing the exact boundary often requires examining the original conveyance or transfer deeds, which may describe the boundary in words or by reference to a plan. The Land Registry's title plans show only general boundaries under section 60 of the Land Registration Act 2002, meaning they indicate the approximate position but are not definitive. People dealing with boundary disputes sometimes find it helpful to obtain copies of both properties' title deeds from the Land Registry, examine any original pre-registration conveyances, and look at historical evidence such as old Ordnance Survey maps or aerial photographs. If the dispute involves a party wall or structure, the Party Wall etc. Act 1996 may be relevant and requires a specific notice procedure. Mediation is often a cost-effective way of resolving boundary disputes, given that litigation costs can quickly exceed the value of the land in dispute.
Common situations
Common situations include: a neighbour building a fence or wall in what you believe is the wrong position, disagreement about who owns or is responsible for maintaining a boundary fence or hedge, a neighbour's extension or outbuilding encroaching onto your land, trees or roots from a neighbour's garden causing damage, a neighbour claiming ownership of land through adverse possession, or confusion arising from vague descriptions in old title deeds.
What UK law says
The Land Registration Act 2002 governs registered land. Section 60 establishes the general boundaries rule, meaning the title plan does not determine the exact boundary. Schedule 6 sets out the procedure for adverse possession of registered land, requiring 10 years' factual possession before an application may be made. The Party Wall etc. Act 1996 applies where work is proposed to a shared wall, boundary wall, or excavation near a neighbour's property, and requires formal notice to be served. Common law principles of trespass and nuisance may apply where there is encroachment. The County Courts Act 1984 provides jurisdiction for boundary disputes, and the court may order declarations as to the boundary position.
What people often consider
People involved in boundary disputes often consider: obtaining copies of title documents from the Land Registry for both properties, instructing a surveyor experienced in boundary disputes to provide an opinion, attempting direct negotiation with the neighbour as a first step, using a mediator to facilitate agreement, applying to the Land Registry for a determined boundary under section 60(3) of the Land Registration Act 2002, or as a last resort, bringing a court claim for trespass or a declaration of the boundary position. The costs of litigation in boundary disputes may be disproportionate, and some people find that a practical compromise is preferable.
Common mistakes to avoid
Common mistakes include: relying solely on the Land Registry title plan to determine the exact boundary (it shows only general boundaries), moving or removing a boundary fence or structure without first establishing the legal boundary, not serving a party wall notice when required before carrying out relevant works, allowing a boundary issue to escalate without attempting early resolution, and not being aware that adverse possession claims may be made where land has been occupied without challenge for the required period.
Frequently asked questions
Who owns the boundary fence between two properties?
Ownership of a boundary fence or wall depends on the title deeds rather than any general rule. A common convention is that the 'T' marks on a deed plan indicate responsibility for maintenance, but this is not universal. If the deeds are silent, ownership may need to be established through other evidence or agreement.
Can my neighbour claim my land through adverse possession?
Under Schedule 6 of the Land Registration Act 2002, a person may apply to be registered as owner of registered land after 10 years of factual possession. The registered owner is then notified and has 65 business days to object. If no objection is made, the applicant may be registered. If an objection is made, the claim will only succeed in limited circumstances.
What is the Party Wall Act and when does it apply?
The Party Wall etc. Act 1996 applies when work is proposed to a shared wall, a boundary wall, or excavation within certain distances of a neighbouring property. The person carrying out the work must serve a formal notice, and if the neighbour does not consent, a dispute resolution process involving party wall surveyors is triggered.
