Your Title Plan Is Not a Boundary Survey
Why Land Registry title plans show general boundaries only, and why measured site features are needed for design or boundary-sensitive work.
A title plan generally identifies the extent of a registered property. A topographical survey records agreed physical features and levels at the time of measurement. These are different kinds of evidence: measuring a fence does not, by itself, decide who owns it or where the legal boundary lies.
What a title plan shows
HM Land Registry explains that title plans normally show general boundaries. The plan should be read with the register and any relevant deeds. A determined boundary is a different situation and needs to be identified from the appropriate records.
The official title-plan guidance explains the role of the plan and the mapping on which it is based. It does not give every property a universal 500mm boundary tolerance. Enlarging a scanned plan or measuring the width of its red line cannot establish an exact legal line.
What physical measurement adds
A topographical survey can record features such as walls, fences, hedge lines and nearby buildings within its agreed scope. It can help a project team understand present site geometry and compare documents with physical conditions.
The scope should identify which features are needed, the required accuracy and coordinate framework, access limitations and intended use. Current measurement does not establish the history of a feature, the interpretation of a deed or the legal effect of an agreement.
| Information | What it can help establish |
|---|---|
| Title plan and register | The registered property and relevant recorded information, subject to their limitations. |
| Relevant deeds and other evidence | Context requiring appropriate professional interpretation. |
| Current topographical survey | The measured position of agreed physical features at the survey date. |
| Legal boundary advice | How the relevant evidence applies to the particular ownership question. |
If there is a dispute
Use the GOV.UK overview of property boundaries to understand the available information and routes. Explain the issue to a suitably qualified adviser before commissioning specialist work. Do not move a boundary feature solely because a title-plan overlay and a measured drawing differ.
Topographical Ltd's public topographical service is a measured site survey. It should not be mistaken for a boundary-dispute opinion or a determined-boundary application. If your designer needs measured physical context for a project, state that requirement clearly; if the question is legal ownership, identify the separate advice required.
