The French real estate market generates a considerable volume of transactions, land divisions, and construction projects each year. Behind each operation lies a technical question often underestimated: the reliability of the land data on which the project is based.
The land surveyor, a liberal professional registered with the Order and entrusted with a public service delegation, specifically addresses this issue. The Betard firm, located in Northern Vaucluse, is among the structures that combine long-standing practice with adaptation to recent developments in the profession.

Property Boundary Disputes: A Tense Context Since the Post-Covid Recovery
Several observatories of real estate claims and law firms specializing in real estate law have reported an increase in disputes related to property boundaries and easements since 2022. Right of way, views, party walls: these issues fuel conflicts that can block a sale or delay a construction project by several months.
In this context, the role of the land surveyor in amicable and judicial expertise has strengthened. Securing boundaries before any transaction helps avoid lengthy and costly procedures. The contradictory boundary marking, the only legally enforceable operation to establish a land boundary, can only be carried out by a land surveyor registered with the Order.

By relying on the land surveyor expertise of the Betard firm, it is possible to cover the judicial aspect within the scope of intervention. Founder Olivier Betard is also an expert with the Court of Appeal. This dual technical and legal role is significant when a neighborhood dispute threatens to escalate.
Energy Renovation and Land Surveyor: A Less Obvious Link Than It Seems
External insulation, extensions, or the installation of solar panels on roofs are increasingly common works. Since 2023, feedback has shown that these heavy energy renovation projects require careful verification of land areas, prospects, and existing easements.
An insulation overhang encroaching on public land or neighboring property, an extension that does not comply with prospect regulations: these errors often come to light at the time of resale or during an inspection. The Order of land surveyors has highlighted this adaptation of the profession to climate challenges in its recent communications.
The Betard firm, with its two ESGT engineers (Olivier Betard and Damien Laval), has the skills to cross-reference topographical data and urban planning regulatory constraints. The available data does not allow for precise quantification of the share of these “energy” missions in the overall activity of a land surveyor firm. The trend exists, but its extent remains to be confirmed.
Digitization of Urban Planning Documents: What It Changes for a Real Estate Project
Since January 1, 2022, the digitization of urban planning permits has been mandatory for municipalities with more than 3,500 inhabitants. The generalization of the Urbanism Geoportal has also changed the way land surveyors access local regulatory data.
In practical terms, this means that boundary plans, modified cadastral parcel documents (DMPC), and topographical surveys are now part of a more streamlined digital chain. The accuracy of the transmitted data determines the validity of the urban planning file.
For a firm like Betard, this transition involves measurement equipment compatible with the digital formats required by the administration. Field feedback varies on this point: some practitioners believe that digitization accelerates procedures, while others find that the information systems of local authorities are not all at the same level of maturity.
Tasks Where Digital Precision Matters Most
- Parcel division for the creation of buildable lots, where an error of a few centimeters can render a lot non-compliant with the local urban plan
- Building placement on site, which requires precise georeferencing to comply with regulatory setbacks from property boundaries
- Topographical surveys intended for soil studies or development permits, whose data directly feeds the infrastructure study software
Regulatory Framework of the Land Surveyor: What Really Protects the Client
The profession of land surveyor is governed by the law of May 7, 1946. Access is protected by a level bac + 5 engineering degree or a DPLG land surveyor degree. This is not a simple voluntary certification: only the land surveyor is authorized to carry out an enforceable boundary marking.
Registration with the Order imposes concrete obligations:
- Compliance with ethical rules monitored by the Order, with the possibility of disciplinary sanctions
- Obligation of continuing education, which ensures an update of skills in the face of regulatory and technical developments
- Subscription to professional insurance and transparency regarding service prices
The Betard firm, established as a SELARL, operates within this framework. The presence of two ESGT engineers within the structure offers processing capabilities that exceed those of an isolated practitioner, especially for projects requiring long-term follow-up (subdivisions, condominiums, complex successions).
Land, Apartment, or Renovation: Adapting the Diagnosis to the Project
A purchase of bare land does not require the same verifications as a division of an apartment in a condominium. In the first case, boundary marking and topographical surveys are priorities. In the second, it is the consistency between the descriptive state of division and the physical reality of the lots that poses a problem.
Each real estate project has its own land vigilance points. A generalist land surveyor firm covers all these situations, but the added value lies in the ability to identify specific risks in advance before they become legal or financial obstacles.
The choice of a land surveyor for a real estate project is not a matter of comfort, but a technical precaution whose consequences are often measured years after the transaction. Projects that skip this step expose themselves to costly corrections, sometimes impossible to carry out once the property is sold or the construction is completed.
