You want to fence your garden, but you do not have a boundary survey. Is this legal? The short answer is yes. The law does not require you to hire a licensed surveyor before installing a fence. However, in practice, proceeding without knowing your exact boundaries is the surest way to end up in court with your neighbor.
The Right to Enclose (and Its Only Real Condition)
Article 647 of the Civil Code is clear: every property owner has the right to fence their land. This is the basic rule. Exceptions are rare, such as in certain subdivisions where boundary surveys are mandatory, or if your neighbor demands a judicial survey.
Outside these cases, you are free to enclose your property, subject to one strict condition: the fence must rest entirely on your own parcel. The slightest encroachment onto your neighbor’s land puts you in the wrong. This is where the absence of official markers becomes problematic. How can you be certain you are not encroaching if the boundary is not marked anywhere?
Encroachment: A Costly Mistake
Without a boundary survey, you are installing your fence blind. If you encroach on the neighboring property, even by a few centimeters, your neighbor has the right to take legal action. French courts are uncompromising on the issue of encroachment. It does not matter whether you acted in good faith or whether the encroachment is invisible to the naked eye: you will be ordered to remove the structure at your own expense.
Even without going to court, an unclear property boundary is a breeding ground for problems. It damages neighborly relations, complicates inheritances, and can even derail the sale of your home. Only a licensed surveyor can legally guarantee where your land ends.
The Cadastre Has No Legal Value
To avoid surveyor fees, the usual reflex is to consult the cadastral plan. Forget this method. The cadastre is used solely to calculate local taxes. Its boundaries are approximate and have absolutely no legal value for establishing a property line.
If you genuinely refuse to pay for an official survey, look for old markers: old walls, remnants of fences, or boundary stones buried under vegetation. Above all, discuss it with your neighbor. If you agree on the dividing line, install your fence with a slight setback on your side. This provides a useful safety margin.
Do Not Forget the Municipal Regulations
Once the land issue is settled, the administrative requirements remain. Before purchasing your posts, consult the Local Urban Plan (PLU) at the planning department.
You cannot do as you please. The municipality may impose a maximum height, prohibit certain materials (such as solid concrete panels), or require specific colors. In the vast majority of cases, you will need to file a prior declaration of works. Installing first and asking for forgiveness later rarely works: a non-compliant fence will have to be removed, particularly near protected areas or historic monuments.
Proceeding with Installation
Once the land is legally ready, all that remains is to choose the materials. If durability is your priority, rigid mesh fencing on set posts is the reliable choice. If privacy is your concern, you will need to opt for screening panels or add a privacy screen.
