Dealing with property boundary disputes

When you are buying a property, your focus is naturally on the home itself: the rooms, the size, the potential. The garden might get a look too. But the boundary is rarely something buyers think carefully about until it becomes a problem.

That is a mistake worth avoiding.

A property boundary can take many forms: a fence, a brick wall, a hedge, another building, a road, a footpath or even a stream. Clear demarcation of responsibilities for each boundary can prevent some very difficult disputes between neighbours.

Bear in mind that the boundary along one side may involve more than one neighbour, which is why it matters to understand who owns what before committing to a purchase. Side passages, front gardens and driveways that abut neighbouring properties all count.

There is a common assumption that the left-hand side of the garden belongs to the neighbour and you own the right-hand side. In practice it varies, and assumptions are where disputes begin.

When you receive the estate agent particulars, you will get a rough layout of the property and its external grounds. As part of the conveyancing process, your solicitor will contact HM Land Registry for all information held on the title of the property. This will highlight the boundaries, though not always with precision, and the mapping held by the Land Registry is not always conclusive.

If there are differences between what the Land Registry holds and what the seller has provided, raise them with your solicitor before you exchange. Getting surveyors to define the precise legal boundaries before completion is the most effective way to avoid a dispute arising with neighbours once you move in. A RICS Level 3 survey at this stage is far less expensive than resolving a dispute after the fact.

It is also worth checking whether any neighbouring developments could affect your right to natural light. You can read more about this in our right to light guide.

Once you are settled, routine boundary maintenance such as mending a fence, trimming a hedge or cutting back trees requires a conversation with your neighbours first. Agreeing who does the work, when and at whose cost avoids misunderstandings before they become disputes.

If you are planning more significant works along the boundary like an extension, a large structure or a new outbuilding, establish boundary ownership before instructing contractors. Surveyors with experience in boundary work can advise on this at an early stage, and their advice can save you considerably more in legal costs down the line. The local planning authority will not check boundary ownership as part of any planning permission process, so that responsibility falls to you.

Always discuss plans with neighbours early and set up a party wall agreement where relevant. Neighbours have the right to enjoy their property as much as you do yours, and dealing with them upfront will significantly reduce the risk of a dispute later.

Even with the best intentions, disputes happen. Boundary disagreements can escalate into court proceedings surprisingly quickly, and the costs involved are rarely proportionate to the size of the land in question.

As soon as a dispute arises that cannot be resolved amicably, instruct a solicitor experienced in property law. You should also seek out surveyors who specialise in boundary disputes. These expert professionals have the skills to interpret maps, aerial photographs, historical documentation and location data from HM Land Registry, and they are well-versed in the civil procedure rules that govern land and boundary disputes. Surveyors working on dispute cases produce detailed reports and formal determinations that carry real weight in any legal process.

Acting early, before positions become entrenched, gives you the best chance of resolving the matter quickly and affordably. Surveyors who offer boundary dispute services can also help both parties reach agreement without going to court, which keeps costs down for everyone involved.

Yes, but it complicates the process. A buyer's solicitor will identify any unresolved boundary dispute during the conveyancing searches and it is likely to raise concerns for mortgage lenders. In some cases it can delay or derail a sale entirely.

If you are selling with a known dispute, you are legally required to disclose it. The most practical approach is to resolve it before going to market. Surveyors can define and ratify the boundaries, producing an official report that can be lodged at HM Land Registry. This gives a future buyer's solicitor a clear and legally sound record of the boundary, which strengthens your position as a seller and reduces the risk of the dispute affecting the sale.

The most effective way to avoid a boundary dispute is to act before one arises. Commissioning surveyors to define the precise legal boundaries either before you buy or shortly after completion means you have an official document, signed by all affected parties, that can be lodged at HM Land Registry.

Surveyors can also provide written advice on boundary responsibilities, maintenance obligations and rights of way as part of their services, which is particularly useful if you are buying a property with a complex title or an unusual plot. That documentation will also form part of the information available to any future buyer's solicitor, making it a genuine selling point when you come to move on.
