Property Boundaries, the Land Registry, and their accuracy
Whether you're planning an extension, repairing a fence, or managing a dispute with a neighbour, understanding your property boundaries is essential. However, it’s also one of the most misunderstood areas of property ownership.
At Harpr Surveyors, we often speak with homeowners confused by the difference between what they see on the ground and what’s shown in legal documents. This post, based on HM Land Registry guidance, will clarify what boundaries are, what information is (and isn’t) recorded, and what to do if problems arise.
TL;DR? Listen to the article.
What Is a Boundary?
Your property boundary is the dividing line between your land and your neighbour’s. This line may or may not correspond with a physical feature such as a fence, wall, or hedge.
There are two types of boundaries to be aware of:
- Physical Boundary: A visible feature like a fence or wall that separates properties.
- Legal Boundary: An invisible line with no thickness in law, marking the precise extent of ownership between two parties.
Legal boundaries are rarely shown precisely in title documents. Even when plans are attached, they are often for identification purposes only, not for defining exact positions.
What Does the Land Registry Actually Show?
When a property is registered for the first time, HM Land Registry creates a title plan based on the latest Ordnance Survey map available at that time. This plan shows the general boundaries of the property, with the extent of ownership outlined in red.
However, there are some important caveats:
- Title plans are not definitive. They are subject to the General Boundaries Rule, which means the red edging only provides a rough indication of the boundary location.
- Map scale matters. Older maps may lack detail or show boundaries differently. A fence shown in one version may appear in a slightly different place in a newer one.
- Mapping tolerances apply. Minor discrepancies between what's shown on a map and what exists on the ground are expected.
In short: title plans are not designed to show exact boundary positions, and should not be used as definitive evidence in a dispute.For homeowners, developers, and solicitors who need professionally drawn plans that meet HM Land Registry submission requirements - such as for transfers, lease registrations, or boundary agreements - we offer Land Registry Compliant Plans. These plans are accurate, clearly drawn, and accepted for all official applications.

Can the Land Registry Tell Me Who Owns or Maintains a Boundary?
This is a common question - and the answer is: usually, no.
Most property title registers do not specify who is responsible for a particular fence or wall. There are no standard legal presumptions (like “you own the fence on the right-hand side”) and no hard rules about which side owns or maintains a boundary feature.
In some cases, responsibility may be indicated:
- Through T-marks on a deed plan, which point into the responsible property.
- Through verbal descriptions in the title register.
- By reference to copy filed documents, which can be requested via form OC2 for a small fee.
If none of these appear in the documents or register, it's likely that ownership of the boundary has never been formally agreed.

Land Registry Compliant Plans – Answers to Your Top Questions
Common Boundary Myths - Debunked
- ❌ "You always own the fence on the left/right."
✅ No legal basis for this presumption exists. - ❌ "The side with the fence posts belongs to the owner."
✅ Not a reliable indicator of ownership. - ❌ "Land Registry will tell me who owns the fence."
✅ Land Registry often doesn’t hold this information.
If you’re ever in doubt, it’s best to discuss with your neighbour first.
What If There’s a Dispute?
The Land Registry cannot resolve boundary disputes or offer legal advice. Their role is to maintain an accurate public register of land ownership - not to act as a mediator.
If you believe a boundary is in the wrong place or are in conflict with a neighbour, you have a few options:
- Talk to your neighbour - Often, a simple discussion can prevent legal headaches.
- Create a boundary agreement - If you agree on the boundary, this can be recorded and registered.
- Determine the boundary - A formal process requiring a surveyor and legal input.
- Seek legal advice - Especially if the issue affects access, development, or property value.
We're in contact with a number of solicitors, not only in Cornwall but all across the UK - if you're stuck for choice, we may be able to put you in contact with a suitable firm. For disputes that escalate, consider professional mediation or contact a surveyor.

Final Thoughts
Understanding your property’s boundaries is crucial - whether you're improving your home or avoiding disputes. While the Land Registry provides a useful starting point, it often doesn’t hold definitive answers. That’s where professional guidance can make a real difference.
