The cadastral map is the Land Register’s map of registered land in Scotland. It is made up of cadastral units: the red-edged plots that show each registered piece of land.

Registers of Scotland states that the ScotLIS map view is for indicative purposes only.

Boundary detail and explanations of coloured lines, tints, or hatches are in the purchased property documents, not in the indicative map view alone.

How does the cadastral map differ from a cadastral unit?

The cadastral map is the whole map of registered land on the Land Register. A cadastral unit is one red-edged piece of that map for a single registered plot.

What does the cadastral map show for my plot?

For each cadastral unit, the map shows

• the cadastral unit number,
• the boundaries of the unit,
• the title number of any registered lease relating to that unit.
• It may also show registered rights where Registers of Scotland chooses to map them.

Subject to a limited exception for pertinents, the same area of land cannot be represented by more than one cadastral unit. The cadastral unit number is the title number of the plot that unit represents.

The map must be based on the base map: the Ordnance Map, another mapping system prescribed by Scottish Ministers by order, or a combination of both. It may show boundaries on the vertical plane, but it does not have to.

How does the cadastral map relate to the title sheet?

Registers of Scotland must make up and maintain a title sheet for each registered plot of land.

Guidance summarises the usual pattern as one registered plot of land, one cadastral unit, and one title sheet, with noted exceptions for leasehold and tenemental properties.

The property section of the title sheet must describe the registered plot by reference to the cadastral map.

A request for an extract of the title sheet does not automatically include the corresponding part of the cadastral map.

What does the cadastral map show for a flat in a tenement?

A cadastral unit that represents a separate tenement must be shown on the map in a way that distinguishes it from other units.

Mapping on the cadastral map does not by itself settle who owns the solum, gardens, or common parts. Title wording does.

What if the home is not on the Land Register yet?

Some Scottish properties remain on the older Sasine Register until an event triggers first registration on the Land Register.

Until first registration, that home will not appear as a cadastral unit on the cadastral map. Not every Scottish home is already shown on it.
