A homeowner in the Nièvre lives next to plots where sheep graze, some of them wearing bells. The tinkling is constant, day and night. He applies to the summary judge (juge des référés, the judge for urgent interim measures) to have an abnormal neighbourhood disturbance stopped and to obtain an interim payment. The farmers reply that the bells protect the flock, that the wolf is back and that biodiversity is in the public interest. On 21 May 2026 the Cour de cassation (the French supreme court for civil matters) upheld the Court of Appeal’s finding of an abnormal disturbance: the noise is not among the characteristic sounds of the local countryside, and guard dogs are enough. The decision is unpublished, but it shows how a neighbourhood disturbance is assessed in the countryside, and what a valuation report can bring to it.
The facts
The neighbour sued the farmers in summary proceedings to stop the manifestly unlawful disturbance resulting from an abnormal neighbourhood disturbance caused, in particular, by the tinkling of bells worn by some of the sheep they graze on plots adjoining his home, and to obtain an interim payment on account of compensation for his loss.
The Bourges Court of Appeal, on 16 November 2023, ruling in summary proceedings, held that the tinkling was a manifestly unlawful disturbance, ordered the farmers to stop it by removing the bells and ordered them jointly to pay an interim sum.
The farmers appealed to the Cour de cassation. They argued that living beings and biodiversity are part of the nation’s common heritage, that protecting the return of the wolf and safeguarding flock animals threatened by that predator made the bells necessary, and that the Court of Appeal, in holding that “the ringing of bells all day and all night, which is not among the characteristic sounds of the rural environment of the Nièvre, constitutes an abnormal neighbourhood disturbance and therefore a manifestly unlawful one”, had not carried out that inquiry.
The decision
The third civil chamber dismissed the appeal (Cass. 3e civ., 21 May 2026, no. 24-10.569). The Court of Appeal had in fact made the inquiry it was accused of omitting. It “found that [the neighbour] proved a constant tinkling of the bells worn by several sheep grazing on the plots, close to his home”, “noted that this continuous tinkling did not constitute characteristic sounds of the rural environment of the Nièvre” and “held that [the farmers] had trained livestock guardian dogs whose presence was in itself sufficient to protect the flock, as shown by the choice of neighbours not to use bells, guardian dogs giving sufficient protection against attempts at predation and theft in sheepfolds”.
From these findings it “sovereignly deduced that the presence of bells on some animals constituted an abnormal neighbourhood disturbance and therefore a manifestly unlawful one”. The decision was legally justified.
What this changes for valuation
Abnormality is measured by the place. The test is not the noise as such, but whether it is abnormal in the environment concerned. In the countryside, the sounds of livestock farming are part of the normal inconveniences; what tipped this case was the permanence of the tinkling, day and night, and the fact that it does not belong to local custom. The trial judges assess this sovereignly; the Cour de cassation reviews only the reasoning. A neighbourhood disturbance case is therefore won on findings: duration, intensity, hours, comparison with neighbouring practice, here the choice of other farmers not to use bells.
Necessity is assessed against the alternatives. The flock-protection argument was not dismissed out of hand: the Court of Appeal found that the guardian dogs, present and trained, were enough. A disturbance that could be avoided by an equivalent means loses its excuse. For the valuer this shapes the report: describe the nuisance, but also the technical solutions available and their cost, because the proportion between the harm suffered and the cost of avoiding it weighs in the judge’s assessment.
Summary proceedings and the interim payment. The case was decided in summary proceedings, on the ground of a manifestly unlawful disturbance, with an interim payment on account of compensation. An interim payment requires a claim that is not seriously disputable in principle and in a minimum amount. A valuation report, even a unilateral one, that quantifies the loss of enjoyment over a period and documents its references gives the summary judge the minimum needed; the full assessment of the loss, including any loss of value of the property, belongs to the judge on the merits.
What is quantified. Two heads: the loss of enjoyment for the duration of the disturbance, most often computed as a fraction of the rental value of the property over the period, proportionate to the inconvenience (rooms affected, hours, seasons); and the loss of value of the property if the disturbance persists or has affected a sale, measured by comparison with equivalent properties not exposed to it. In this case, the removal of the bells ordered by the court ends the disturbance, and compensation is then limited to the period that has elapsed.
The law of 15 April 2024. Article 1253 of the Civil Code, in force since 17 April 2024, codifies strict liability for a disturbance exceeding the normal inconveniences of neighbourhood. It excludes that liability, subject to article L. 311-1-1 of the Rural and Maritime Fishing Code, where the disturbance comes from activities existing before the deed of acquisition or the entry into possession of the person harmed, provided they comply with laws and regulations and have continued under the same conditions, or under new conditions that do not aggravate the disturbance. The decision commented on, given in summary proceedings on the general principle, does not apply it; but for any new case, the prior existence of the activity and the aggravation of the disturbance become the first questions to document, with dates of acquisition and the history of the farm.
What the valuer takes from it
- An abnormal disturbance is judged in its environment: in the countryside, permanence and departure from local custom are what characterise it.
- The excuse of necessity falls when an equivalent means exists; the report describes the alternatives and their cost.
- In summary proceedings, a documented quantification of the loss of enjoyment is enough to found an interim payment; loss of value is argued on the merits.
- Loss of enjoyment is computed from rental value and the period; loss of value by comparison with unexposed properties.
- Since article 1253 of the Civil Code, the prior existence and lawfulness of the neighbouring activity are checked before any figure.

The Property loss of value page describes the valuation of a loss of enjoyment or a loss of value, its timescale and its fee. The glossary entries trouble anormal de voisinage and perte de jouissance and the guide My neighbour is building a block of flats, my house loses value complement this article. On the same theme: Nuisance and loss of view: not automatic and Sale annulled for noise: the lost chance of a capital gain must be certain. The decision is available on Légifrance, and so is article 1253 of the Civil Code.
