What Is a Boundary?

A property's legal boundary is the precise line that separates your land from your neighbour's. The physical boundary is the feature - fence, wall, hedge - that marks it on the ground. The two do not always coincide, and that gap is the source of most disputes.

How Boundaries Are Recorded

The Land Registry holds title plans for registered properties but uses a general boundaries rule: plans are drawn to a scale of 1:1250 (urban) or 1:2500 (rural), and lines on them are simply indicative, not precise. The precise boundary must be found in the title deeds, including old conveyances, transfers, and any attached plans.

Common Boundary Disputes

  • Who owns the fence or wall between two properties
  • Encroachment by a building, extension, or fence
  • Disputed ownership of a strip of land
  • Driveway or access disputes
  • Overgrown hedges and roots affecting the neighbour's land

Gathering Evidence

Before doing anything else, gather your title deeds and historic conveyances, aerial photographs from Google Earth or Ordnance Survey, old photographs showing the position of fences or walls, planning documents mentioning the boundary, and witness statements from long-term neighbours.

Who Owns the Fence?

There is no universal rule that the left or right fence belongs to a particular owner. Ownership depends on what the deeds say. If the deeds show a "T" mark touching the boundary line, the property on the side the stem points to normally owns and maintains that feature.

Dispute Resolution Pathways

Negotiation

Most boundary disputes can and should be resolved by direct negotiation. A boundary agreement can then be drawn up, signed, and registered with the Land Registry.

Mediation

A neutral mediator can help both parties reach a binding settlement. Mediation typically costs £500 to £2,000 per party and is much cheaper than litigation. Courts increasingly expect parties to attempt mediation before issuing proceedings.

Land Registration Boundary Determination

You can apply to the Land Registry to determine an exact boundary. This requires a detailed survey and plan. If your neighbour objects, the matter is referred to the First-tier Tribunal (Property Chamber).

Litigation

Court proceedings over a boundary strip are notoriously expensive. Costs of £50,000 or more are not unusual for disputes about a sliver of garden. Always explore alternatives first.

Practical advice: Never move or build over a disputed boundary line before seeking legal advice. Doing so can amount to trespass and will significantly weaken your position in any subsequent dispute.
