Purchasing property in Martinique requires particular vigilance regarding easements that may encumber the property. These legal constraints, often unknown to buyers, can significantly impact the use and valuation of land or a house. In this comprehensive guide, Cabinet Laurent Valère explains everything you need to know about easements in Martinique.
What is an Easement?
Legal Definition
An easement is a charge imposed on one property (the servient estate) for the benefit of another property (the dominant estate), according to Article 637 of the French Civil Code. This constraint creates a real property right that binds two distinct properties, even if their owners change.
Fundamental Principles
In Martinique, as in mainland France, easements follow three essential principles:
- Perpetuity: the easement persists until extinguished according to legal procedures
- Indivisibility: it applies to the entire estates, even in case of division
- Accessory: it automatically transfers with the property during a sale
Martinique Specificities
Martinique presents particularities that make certain easements particularly important:
- The hilly terrain multiplies the need for right-of-way easements
- Proximity to the sea generates specific coastal easements
- Natural hazards (hurricanes, earthquakes) impose public safety easements
- The often overhead electrical network creates numerous utility line easements
Types of Easements
Legal Easements
These easements are imposed by law, without need for agreement between owners.
Right-of-Way Easement
Particularly common in Martinique due to the terrain, it allows access to landlocked property. According to Article 682 of the Civil Code, any owner whose land is landlocked can claim passage over neighboring lands for compensation proportionate to the damage caused.
In Martinique practice:
- Compensation ranges between 3 to 10% of land value depending on inconvenience
- The passage must follow the shortest route and be least damaging
- Local jurisprudence often favors existing traditional paths
View and Prospect Easement
Article 678 of the Civil Code imposes minimum distances for openings facing the neighbor:
- 1.90 meters for direct views (windows, French doors, balconies)
- 60 centimeters for oblique views
Special attention in Martinique: local case law considers varangues (Creole verandas) as direct views requiring the 1.90m distance.
Water Flow Easement
Crucial in tropical climate, Article 640 of the Civil Code requires that lower lands receive rainwater naturally flowing from upper lands. In Martinique, this easement is even more important given:
- Abundant rainfall (up to 4,000 mm/year in the north)
- Steep slopes accelerating runoff
- Risks of flooding and landslides
The lower owner cannot obstruct this natural flow, but the upper owner cannot aggravate it.
Party Wall Easement
It governs walls, fences and hedges separating two properties. In Martinique, the maximum height of a party wall is 3.20 meters in urban areas according to local customs, but may vary according to municipal PLUs.
Coastal Easements
Specific to French overseas territories, several easements protect Martinique's coastline:
- Coastal passage easement (3 meters from shoreline) to allow public access
- 50 geometric steps zone (approximately 81.20 meters) inherited from colonial history, where the State retains rights
- Wooded area protection easement in mangrove zones
Cabinet Laurent Valère regularly assists clients facing these complex coastal easements, particularly during seaside acquisitions.
Public Utility Easements (SUP)
They are established in the name of general interest and must appear in urban planning documents.
Risk Prevention Plan Easements
Martinique being exposed to multiple natural hazards, PPRNs (Natural Risk Prevention Plans) impose strict easements:
- Red zones (non-buildable) due to seismic, hurricane or flood risks
- Blue zones (buildable under conditions) with reinforced earthquake-resistant construction requirements
- Setback easements from ravines and watercourses (generally 10 to 30 meters)
Historic Monument Protection Easements
Several hundred Martinique buildings are protected. A 500-meter protection perimeter around classified monuments requires authorization from the Architect of Buildings of France (ABF) for any construction or modification.
Notably affected: Fort-de-France (Schœlcher library, Saint-Louis cathedral), Saint-Pierre (city ruins), classified colonial estates.
Aeronautical Easements
Martinique Aimé Césaire Airport in Lamentin imposes clearance easements limiting construction height in an extended radius. These easements affect several municipalities: Lamentin, Ducos, Saint-Joseph, and partially Fort-de-France.
Public Utility Network Easements
They allow passage and maintenance:
- EDF: easements for high and medium voltage lines (generally overhead in Martinique)
- Drinking water networks: easements for pipes and equipment (SME, CACEM, Cap Nord)
- Sanitation: easements for collectors and treatment plants
- Telecommunications: easements for cables and antennas
Warning: in Martinique, with the electrical network being predominantly overhead, EDF easements are particularly numerous and can limit plantings and construction under lines.
Conventional Easements
They result from an agreement between owners and are established by notarial deed.
Conventional Right-of-Way
Unlike legal easement, it is freely negotiated. In Martinique, agreements often concern:
- Access to agricultural plots (banana plantations, sugarcane fields)
- Passage for private ravine maintenance
- Access to traditional water sources
The price of a conventional right-of-way easement ranges between €2,000 and €15,000 depending on length, width and inconvenience caused.
Non-Construction Easement
It can be established to:
- Preserve a panoramic view (particularly prized on mornes with sea views)
- Maintain a buffer space between properties
- Protect a natural or landscape area
Common Courtyard Easement
Common in Martinique urban centers (Fort-de-France, Schoelcher), it organizes shared use of a courtyard between several owners, often in former divided properties.
How to Identify Easements Before Purchase?
Documents to Consult
Mortgage Statement
Provided by the notary, this document lists all published easements at the land registry service. However, beware: certain legal easements may not systematically appear there.
Urban Planning Certificate
The CU (certificat d'urbanisme) mentions public utility easements (SUP) affecting the land. It is issued free by the town hall and constitutes an essential document before any purchase.
Cabinet Laurent Valère systematically recommends requesting an operational urban planning certificate (CUb) rather than a simple information certificate (CUa), as it precisely informs on buildability.
Local Urban Plan (PLU)
The PLU maps public utility easements in its appendices. In Martinique, particularly consult:
- Zoning plans (buildable/non-buildable zones)
- PPRN plans (natural risks)
- Coastal easements (50 geometric steps)
- Reserved locations (future public projects)
Physical Land Inspection
A thorough visit allows identifying easement indicators:
- Traced paths suggesting traditional passage
- Electrical poles and overhead lines
- Visible pipes or access manholes
- Water flow traces indicating regular drainage
Seller's Obligations
Duty to Inform
According to Article 1602 of the Civil Code, the seller must deliver property conforming to description. Regarding easements:
- Must declare all known easements in the preliminary sales agreement
- Omission of an easement may constitute defect of consent justifying cancellation
- Jurisprudence considers that an undeclared significant easement can substantially reduce property value
Mandatory Diagnostics
The technical diagnostic file (DDT) in Martinique must notably include:
- Risk statement (ERNT/ERNMT) mentioning easements related to natural risks
- Energy performance diagnosis (DPE)
- Termite diagnosis (mandatory throughout the island)
- Asbestos and lead diagnosis depending on age
Notary's Role
The notary performs a complete mortgage search and:
- Verifies existence of published easements
- Questions the land registry service
- Examines previous property titles
- Alerts buyer to identified easements
Warning: the notary is not required to search for unpublished easements or easements by prior unity of ownership (apparent easements created by division of same property).
Impact of Easements on Purchase
Impact on Property Value
An easement can significantly depreciate property:
- Right-of-way: 5 to 20% discount depending on passage intensity
- High voltage power line: 10 to 30% discount for buildable land
- Red PPRN zone: often unsaleable land or discount exceeding 50%
- View easement: construction limitation potentially reducing value by 10 to 25%
Cabinet Laurent Valère, real estate appraisal expert since 1985, systematically integrates easement analysis in its appraisals to provide accurate and realistic valuation.
Impact on Construction Project
Before buying building land in Martinique, verify that easements don't compromise your project:
- A right-of-way may prohibit automatic gate construction
- An EDF line may prevent construction in safety zone
- A drainage easement may require gutter development
- A PPRN setback zone may drastically reduce buildable area
Impact on Daily Use
Certain easements affect comfort and privacy:
- Frequent passage of neighbors or vehicles
- Inability to fully fence the property
- Mandatory maintenance of structures (ditches, pipes)
- Access by EDF agents or other public services without prior authorization
What to Do Facing a Problematic Easement?
Negotiate Purchase Price
Discovering a significant easement should lead to:
- Renegotiating price downward (generally 5 to 30% depending on impact)
- Requesting work from seller (access development, drainage...)
- Having easement assessed by expert (Cabinet Laurent Valère offers this service)
Request Extinction or Modification
Extinction by Non-Use
Article 706 of the Civil Code provides that an easement extinguishes after 30 years of non-use. In Martinique, this prescription is difficult to establish for right-of-way easements, as even occasional use (once yearly) suffices to maintain the easement.
Easement Buyout
Negotiating the buyout of conventional easement with dominant estate owner is possible. Price varies according to easement utility for dominant estate.
Route Modification
For right-of-way, Article 701 allows servient estate owner to propose an alternative route equally convenient for dominant estate. This modification requires amicable agreement or judicial decision.
Court Challenge
In case of dispute, several remedies exist:
- Challenge action if easement is irregular
- Reduction action if easement is excessive
- Damages action if dominant owner abuses right
- Compensation determination action for legal easement
Competent jurisdiction in Martinique is Fort-de-France Judicial Court. Prescription to challenge easement is generally 5 years from discovery.
Creating an Easement: Instructions
Conventional Easement
To create conventional easement between neighbors:
Deed must mention:
- Precise cadastral identification of servient and dominant estates
- Exact easement description (route, dimensions)
- Maintenance procedures and cost sharing
- Possible compensation
Easement by Prior Unity of Ownership
When single owner divides property into two parcels with existing development (path, pipeline), easement can arise automatically if:
- Development is apparent (visible)
- It is permanent (not temporary)
- It creates service relationship between two estates
Warning: this easement must be expressly maintained in sale deed, otherwise it extinguishes according to jurisprudence.
Cabinet Laurent Valère's Practical Advice
With over 35 years of experience in Martinique, our team recommends:
Before Purchase
During Transaction
After Purchase
Special Cases in Martinique
Hilly terrain: favor surveyor expert to precisely materialize right-of-way easements on sloped land.
Coastal zones: imperatively verify exact land status regarding 50 geometric steps with DEAL (Direction de l'Environnement, de l'Aménagement et du Logement).
Agricultural zones: beware unpublished traditional easements (livestock passages, water source access) still practiced in rural areas.
Old constructions: colonial estates may benefit from or suffer specific easements related to former agricultural domains.
Conclusion
Easements constitute a technical but fundamental aspect of property purchase in Martinique. Their precise identification and understanding prevent costly disappointments and lasting neighborhood conflicts.
The island's particular terrain, exposure to natural risks, protected coastline and history create a context where easements are particularly numerous and varied. Increased vigilance is therefore essential during any real estate transaction.
