Reality Anchor: The "General Boundaries" Trap

The Scenario

In Clapham & Wright v Narga, neighbors in Leicestershire disputed the position of a boundary fence. One party relied heavily on the HM Land Registry Title Plan—specifically, the red line drawn on the digital Ordnance Survey map—to argue that the fence was encroaching on their land.

The Technical Error

The core error was treating the coordinates of the Title Plan line as definitive evidence of the legal boundary to within inches. Under the UK's General Boundaries Rule (Land Registration Act 2002, Section 60), the red line indicates the general position of the boundary but does not determine the exact line.

The digital map had limited accuracy (often +/- 1-2 meters or more in rural areas), yet it was being used to contest a fence line that had been physically accepted on the ground.

The Litigation & Outcome

The Court of Appeal rejected the argument that the Title Plan line was superior to the physical evidence.

• Physical Evidence Wins: The court found that the physical fence, which had been in place and accepted, represented the true legal boundary.
• Plan Limitations: The judge emphasized that Title Plans cannot be scaled to determine precise ownership limits in the absence of a "Determined Boundary" application.
• Cost Consequence: The party relying on the digital map coordinates faced significant legal costs for pursuing a claim that contradicted the physical reality.

Professional Lesson

The Map is Not the Territory.
