Applying for official measurement of a property

Last update

Any property owner may request a measurement of their property in order to have an official cadastral survey (MO) plan produced that is showing the boundaries of their plot and its contents.

The official measurement includes:

  • re-establishing the demarcation; and
  • where applicable, the amicable demarcation of the boundaries.

In the case of subdivisions for building purposes or subdivisions for property transactions, new plots are created and described by an MO plan, which must be drawn up by an official surveyor (GO). This plan serves as the basis for property transactions.

The purpose of the request for measurement may be limited to defining and physically marking the property boundaries, with or without drawing up an MO map. If necessary, the official surveyor (GO), in the presence of all the owners concerned, or their representatives, may carry out an amicable demarcation, followed by a demarcation and boundary recognition report signed by all the parties involved. If an attempt at amicable demarcation fails, the GO will draw up a report of failure to demarcate (procès-verbal de carence), which will enable the most diligent party to bring an action for judicial demarcation.

If the purpose of the measurement request is to draw up topographical plans that are required for a special development plan (PAP), based on a topographical survey, the interested party is asked to contact an official surveyor in the private sector.

By using the online procedure on, each owner can submit an application for measurement to:
