The **French Civil Code** outlines specific rules regarding the planting of trees near property boundaries. Article 671 states that trees taller than two meters must be planted at least two meters away from the boundary, while smaller plants require a minimum of fifty centimeters of space. These distances are typically defined by local laws or long-standing customs. In Paris, for example, a local custom allows planting right up to the property line because the parcels are usually small. If these distances are not met, a neighbor can request the removal or trimming of the tree under Article 672, unless the tree is part of a family estate or protected by a specific legal title. Neighbors do not need to prove damage to request the trimming or removal of trees that violate these rules, unlike cases involving more general disturbances. The height of a tree is measured from its base to its top, not accounting for the slope of the land. The required distance is measured from the property boundary to the middle of the tree’s trunk, a detail that is often overlooked. Any legal action must be directed at the property owner, not the tenant, and if the property is co-owned, all owners must be involved. The **Court of Cassation**, France’s highest court for civil matters, has ruled that preventive condemnations—removing trees based on a future risk—are not allowed, as it cannot be assumed a property owner will neglect pruning responsibilities. Defenses to protect a tree include the thirty-year prescription under Article 672, which allows a tree to remain if it has been over the legal height limit for that long. This defense does not, however, prevent a neighbor from trimming branches that encroach on their property. Local urban planning regulations, such as **local urban planning schemes** (PLU), are becoming increasingly important as legal defenses. If a PLU requires tree preservation or mandates authorization for removal, it can override the rules in Articles 671 and 672. PLUs can also restrict trimming if the tree is designated as a notable or ancient tree. Courts have increasingly recognized the importance of preserving trees, emphasizing the need to avoid actions that could endanger the tree’s survival. Contractual agreements, such as those found in development covenants, can also override Article 673 if they specifically protect trees. However, the wording of the clause is crucial—courts have rejected attempts to extend prohibitions on cutting down trees to include trimming without clear justification. Environmental factors are also emerging as a defense, with some courts acknowledging the ecological value of ancient or notable trees. In these cases, the legal obligation may be limited to regular maintenance rather than full removal. These cases are still rare, but they suggest a growing awareness of the importance of preserving ecologically significant trees. For property owners, practical steps include gathering evidence of the tree’s age and when it exceeded legal height limits, consulting local regulations and covenants, and seeking an arborist’s assessment of the impact of trimming. Offering reasonable alternatives, such as measured trimming, can demonstrate a willingness to resolve the issue amicably. For neighbors seeking action, precise measurements, knowledge of local customs, and access to urban planning documents are essential. A mandatory attempt at resolving the dispute amicably is required for planting distance disputes. If a court orders an irreversible action, an appeal to the court president may be necessary to temporarily halt the order.
