Sub-Division Diagram Example

The diagram is the fundamental registerable document prepared by the land surveyor. The essential information shown on a diagram is:

  • The unique designation of the property.
  • An illustration depicting the property.
  • The boundary description listing the corner beacons and the details of any curvilinear boundary.
  • Descriptions of the corner beacons.
  • A table listing the numerical data of the boundaries.
  • The area of the property.

The Surveyor-General gives each diagram a unique reference number.

The most common type of diagram is a subdivisional diagram. This is framed for the purpose of cutting off a portion of a parent property.

There are other types of diagrams however, including:

  • Servitude diagrams for registering servitudes over an existing property.
  • Lease diagrams for registering long leases over portions of properties.
  • Consolidation diagrams when it is required to consolidate several individual properties into one, taking out certificates of consolidated title.
  • Mineral diagrams to register mineral rights separately from the land rights.
  • Mining title diagrams for registering the right to extract minerals from the land.

    With the exception of mining title diagrams, which are registered with the Department of Minerals and Energy, these diagrams are registered together with their deeds in a deeds registry.

    Some other Titles you may be asked about.
