Usually, no. The red edging on an HM Land Registry title plan normally shows the general position of the registered land. It should not be treated as a precise measured line on the ground.
What the title plan is useful for
It identifies the registered title and shows its general extent. It is often an important starting point, but it is not normally enough by itself to decide whether a fence or wall is 100 mm to one side of the legal boundary.
What should be considered with it?
The relevant transfer or conveyance, deed wording, deed plans, physical features that existed when the land was divided, historic photographs and other admissible evidence may all matter. HM Land Registry's own guidance says that where a plan is insufficiently clear, the court can refer to extrinsic evidence, particularly physical features on the ground at the time.
Do not scale a legal boundary from the red line
The scale and purpose of the title plan make this unsafe. A title plan is not a substitute for a careful evidence review.
If the red line and the fence appear different
That difference does not by itself prove that either is wrong. An Early Neutral Evaluation can help identify whether the documents and site evidence justify further investigation.
Need an evidence-led view?
For an early-stage assessment, consider an Early Neutral Evaluation. For a developed dispute, a fuller investigation report may be appropriate.
