If doubts exist regarding the boundary lines of a developed or undeveloped plot of land, the interested parties may apply to the Land Registry and Topography Administration (Administration du cadastre et de topographie - ACT) to have the property boundaries demarcated.
In the presence of all owners whose land touches the boundary in question, the ACT will carry out an amicable demarcation, which is endorsed on the spot in a demarcation agreement duly signed by all owners affected.
If the attempt to demarcate the property amicably fails, the affected owner may apply to the competent judge for a judicial demarcation.
The relevant application form—and, where applicable, its annexes—may be filled in, signed and sent electronically to the competent body (refer to the instructions on the cover page of the form).

Who is concerned
Anyone who owns developed or undeveloped land and wishes to ensure that the boundaries of their property are consistent with the cadastral map.
How to proceed
Interested parties may submit their boundary demarcation application to the ACT using an application form, which is to be filled in by the applicant.
For the plot of land in question, the applicant is asked to provide the following information:
- the commune;
- the section of the commune;
- the land registry number.
This information can be obtained from the ACT or, possibly, from the communal administration in question.
The competent regional bureau of the ACT will then notify the applicant, by post, of the surveyor who will carry out the measurements. Once they have received that letter, the applicant can arrange an appointment for the measurements to actually be carried out.
Given that the property boundaries will be established in the presence of all parties, the applicant agrees to invite the owners of bordering properties to attend the measurement.
