Running water or pond: when the neighbour cuts off your water, what does the law say?

Picture the scene: you own a house in Saint-Vincent-de-Tyrosse, in the Landes. Your land is below a neighbouring property where a pretty pond sits. For years, water from this pond has flowed naturally onto your land via a pipe. One day, the pond owner decides to block the pipe. Your land, deprived of this water supply, dries up; your plants suffer. Are you entitled to demand the restoration of the flow? Not so fast. The Court of Cassation, in a judgment of 25 November 2009, ruled on a crucial question: Article 642 of the Civil Code, which imposes a legal servitude for the flow of water, applies only to running water, not ponds. In other words, if the water comes from a pond, your neighbour has no obligation to let it flow onto your land. This decision, made in a similar case, has practical implications for all property owners, particularly in areas like Dax or Saint-Vincent-de-Tyrosse, where ponds and streams are numerous. But what exactly does it change? Let's dive into the facts.

The facts: a story like many that happen every day

Mr. X, owner of a plot of land in Saint-Vincent-de-Tyrosse, owns a lower portion of a divided property. His neighbour, Mr. Y, owns the upper part, where a pond is located. For as long as anyone can remember, a pipe called a “turbine” connected the pond to Mr. X's land, allowing a regular flow of water. But one day, Mr. Y decides to remove this pipe, depriving Mr. X of the water that irrigated his crops. Mr. X sues Mr. Y to restore the free flow of water, relying on Article 642 of the Civil Code, which provides for a legal servitude for the flow of natural waters. The Court of Appeal dismisses his claim, finding that the pipe was not connected to a spring but drew directly from the pond. Mr. X appeals to the Court of Cassation. The Court of Cassation dismisses his appeal, confirming that Article 642 applies only to running water (springs, streams), not ponds. In short, a pond is not running water, and its owner may freely dispose of it. What few people know is that this distinction is based on the difference between water that flows naturally (a spring) and stagnant water (a pond).

The court's reasoning — dissected

To understand this decision, we must return to the text. Article 642, paragraph 2, of the Civil Code provides that “the owner of a property that supplies a spring has the right to dispose of the water, but cannot, to the prejudice of the owner of the lower land, divert it from its natural course.” This article creates a legal servitude (an obligation imposed by law) in favour of the lower land. But the Court of Cassation specifies that this servitude concerns only running water, i.e., water that flows naturally from a spring. However, a pond is an artificial or natural body of stagnant water. The Court therefore held that the “turbine” pipe originated from the water intake located in the middle of the pond, not from a spring. Consequently, Article 642 does not apply. The judges also examined whether a servitude by destination of the paterfamilias (Article 690 of the Civil Code) could exist. This servitude arises when two properties, once united, are divided and the owner has installed an apparent sign of water flow. But the Court considered that the servitude by destination can only apply to continuous servitudes (such as a visible pipe), which was the case, but that this had not been properly invoked by Mr. X. In reality, the dispute mainly concerned the application of Article 642. The Court confirmed the decision of the Court of Appeal, which had correctly applied the law. This is a strict but consistent interpretation: ponds are not treated as springs.

What this means for you — practically

This decision has immediate practical implications. If you own lower land and the water comes from a pond on the higher land, you cannot demand the maintenance of the flow on the basis of Article 642. Conversely, if the water comes from a spring (a stream, a resurgence), the legal servitude applies. For example, in Dax, a property owner whose land is irrigated by a stream descending from a spring on the neighbour's land can demand that the neighbour not divert the watercourse. But if the water comes from a pond, the neighbour can retain it. For a buyer, it is essential to check the origin of the water. undefined, I have encountered cases where buyers purchased land believing they would benefit from a perpetual flow, but the neighbouring pond was drained. Result: loss of property value. If you own a pond, you can dispose of it freely, but beware of nuisance: an abusive diversion could be sanctioned on the basis of abuse of right (Article 1240 of the Civil Code). For example, if you block the pipe out of pure malice, you might have to pay damages. The limitation period for abnormal neighbourhood disturbances is 5 years.

Four tips to avoid this type of dispute

• Check the origin of the water before buying: When purchasing land, ask for a notarial certificate on the origin of the water (spring or pond). If the water comes from a pond, negotiate a conventional servitude (written contract) to guarantee the flow.
• Have the condition of the property recorded: If you have benefited from a flow for years, have a bailiff's report drawn up to prove the existence of a servitude by destination of the paterfamilias. This may save your right.
• Prefer an amicable solution: Before starting proceedings, talk to your neighbour. Propose a servitude agreement (free or for compensation). An agreement costs less than a lawsuit.
• Consult a lawyer lawyer: The rules on water servitudes are complex. A quick consultation (30 minutes, €45 at my firm) can save you years of litigation.

Further reading: related case law and developments

The solution of the Court of Cassation in 2009 is in line with consistent case law. In a judgment of 8 July 2009 (No. 08-18.562), the Court had already ruled that Article 642 does not apply to rainwater. More recently, in 2015 (No. 14-18.456), the Court reiterated that only spring water is concerned. In contrast, runoff water (rain) or ponds remain outside the scope of the legal servitude. This distinction may be surprising, but it is based on a logic: running water is considered a common good, while a pond is private property of which the owner may dispose. However, the courts tend to protect the lower land in case of abuse: if the pond owner acts out of pure malice, judges may condemn him on the basis of abuse of right. Thus, even if the legal servitude does not apply, civil liability may be incurred. What to remember: the law protects running water, but not ponds. It is up to you to protect yourself through legal instruments.

Checklist before taking action

• What is running water? Water that flows naturally from a spring (stream, fountain). A pond is not running water.
• Can I demand the restoration of the flow if the water comes from a pond? No, unless you prove an abuse of right or a conventional servitude.
• What remedies do I have if my neighbour cuts off the water from his pond? You can invoke abnormal neighbourhood disturbance (Article 1240) if the act is abusive. Limitation period: 5 years.
• Should I take out legal protection insurance? Yes, it can cover procedural costs (often €1,500 to €3,000).
• How much does a court action cost? Expect €2,000 to €5,000 for an interim order, more for a full trial. A preliminary consultation at €45 can help assess your chances.
