Imagine: you have just purchased a beautiful villa in Cannes, with a sea view and a garden. Everything seems perfect. But a few weeks after moving in, your neighbour informs you that his wastewater has been crossing your land for thirty years, and that he has acquired a definitive right by prescription (that is, by the passage of time). You are furious, but also worried: is this possible? This question was put to the Court of Cassation in 2004 by a property owner in Vallauris. And the answer is clear: no, a wastewater drainage easement cannot be acquired by the mere passage of time, because it is discontinuous.
But what exactly does this change? In law, easements (real rights over another's property) are distinguished according to whether they are continuous or discontinuous. A continuous easement requires no human intervention to be exercised (e.g., a right of view, an overhang easement). A discontinuous easement, on the contrary, requires a repeated human act (e.g., a right of way, a flow of wastewater that only functions when a toilet is flushed). However, only continuous and apparent easements (indicated by visible structures) can be acquired by thirty-year prescription (Article 690 of the Civil Code). Discontinuous easements, even if apparent, cannot be so acquired.
This decision, rendered by the Third Civil Chamber of the Court of Cassation on 8 December 2004 (appeal no. 03-17.225), confirms settled case law: for a drainage easement to be acquired by prescription, it would need to be continuous, which is not the case where the flow depends on human actions (use of toilets, discharge of household water). In clear terms, even if the pipe is visible and old, the right is not automatically acquired.
The Facts: A Story That Happens Every Day
Mr X, a property owner in Cannes, owns a plot (no. 26) adjacent to that of Mr and Mrs Y (no. 28). For decades, the wastewater from the Ys' house has flowed via a pipe crossing Mr X's plot. Mr X, weary of this situation, sues the Ys to stop the flow and obtain damages (financial compensation). The Ys counter that they benefit from a mains drainage easement acquired by thirty-year prescription (Article 690 of the Civil Code), and that, furthermore, they have a right of way "à talons" (a pedestrian right of way) over the same area.
The Tribunal de Grande Instance of Cannes, and subsequently the Court of Appeal of Aix-en-Provence, hear the case. The trial judges must determine whether the drainage easement is continuous or discontinuous. They examine the structures: an underground pipe, visible on the surface through inspection chambers, but whose flow only occurs when the Ys use water or the toilet. In other words, the flow is not permanent; it is triggered by human acts. The Court of Appeal finds that the easement is discontinuous and could not have been acquired by prescription. It dismisses the Ys' claim for recognition of the easement.
The Ys appeal to the Court of Cassation. They argue that the drainage easement is apparent (the pipe is visible) and that, therefore, it can be acquired by thirty-year prescription, regardless of its continuous or discontinuous nature. However, the Court of Cassation does not follow them: it recalls that Article 690 of the Civil Code requires the easement to be both continuous and apparent to be acquired by prescription. However, a wastewater drainage easement is discontinuous because its exercise requires a human act (the action of flushing a toilet, turning on a tap) and cannot continue without repeated intervention. The appeal is dismissed. The Ys definitively lose their alleged right.
What few people know is that this case illustrates a typical conflict on the Côte d'Azur, where plots are often narrow and old pipes were not formalised by notarial deed. undefined, I have encountered cases where property owners in Vallauris found themselves in the same situation, discovering after acquisition that their land served as the neighbour's drain.
The Reasoning of the Court — Analysed
The crux of the debate concerns the interpretation of Articles 688 and 690 of the Civil Code. Article 688 defines continuous easements as those whose use is independent of any human act (e.g., a right of view, an easement not to build). Discontinuous easements are those that require a current human act to be exercised (e.g., a right of way, a right to draw water). Article 690 provides that easements
