Compulsory purchase for public interest is an exceptional procedure through which the State or a local authority can compel a property owner to transfer their real estate. In Martinique, this issue takes on particular importance in the context of territorial development projects, natural disaster prevention, and infrastructure development.
This guide explains your rights, the expropriation procedure, compensation terms, and possible legal remedies.
What is Compulsory Purchase for Public Interest?
Definition and Legal Framework
Compulsory purchase for public interest is governed by the French Code of Expropriation for Public Interest (Code de l'expropriation pour cause d'utilité publique). This procedure allows a public entity (State, Territorial Collectivity of Martinique, municipalities) or a private beneficiary acting on behalf of a public interest mission to become the owner of a property against the owner's will, in exchange for fair compensation.
Projects Concerned in Martinique
In Martinique, expropriation typically occurs for:
- Road infrastructure: widening of the National Road (RN), bypasses, new routes
- Natural disaster prevention: acquisitions in areas exposed to landslides (Prêcheur, Morne-Rouge, Fonds-Saint-Denis)
- Urban development: ZAC projects, public facilities, social housing
- Environmental protection: creation of protected natural areas, coastal protection zones
- Public facilities: schools, hospitals, treatment plants
- Public transportation: TCSP project (Public Transport on Reserved Lane) in central Martinique
The Territorial Collectivity of Martinique (CTM) and municipalities such as Fort-de-France, Schoelcher, Le Lamentin, and Le Robert regularly face these procedures as part of their development.
The Expropriation Procedure: Key Steps
Administrative Phase: Declaration of Public Interest
1. Preliminary Investigation
Before any expropriation, a public inquiry is organized to assess the project's usefulness. Affected property owners are notified by mail and can review the file at the town hall. This phase typically lasts one month.
Important note: Always participate in this inquiry to present your observations. The investigating commissioner will issue an opinion that will influence the final decision.
2. Declaration of Public Interest (DUP)
After the inquiry, the Prefect of Martinique (or the Minister for nationally significant projects) may issue the DUP by decree. This decision:
- Validates the public interest of the project
- Authorizes the expropriation of necessary properties
- Is valid for 5 years (renewable once for 5 years)
3. Order of Transferability
A second prefectoral order precisely determines the affected parcels and their owners. This order is individually notified to each owner and published in the land registry (service de la publicité foncière).
Amicable Phase: Attempt at Agreement
Compensation Proposals
The expropriating party must attempt to reach an amicable agreement before referring to the judge. They send the owner a detailed compensation proposal.
Negotiation period: The owner typically has one month to accept or refuse this offer.
Cabinet Laurent Valère's advice: Don't rush. This initial proposal is often lower than the property's actual value. Request a counter-appraisal and seek assistance from a real estate professional familiar with the Martinique market.
Property Valuation
The administration relies on the opinion of the France Domaine service (formerly Domaines) to determine the property's value. In Martinique, this assessment must consider:
- Market price per m² in the concerned municipality
- Specific property characteristics (sea view, access, cyclonic exposure)
- Improvements made
- Legal situation (title deed, easements)
- Regulatory constraints (PPRN, PLU)
Judicial Phase: Intervention of the Expropriation Judge
Referral to the Judge
If no amicable agreement is reached, the expropriating party refers to the expropriation judge at the Fort-de-France judicial court. This procedure includes two steps:
Role of Judicial Appraisal
The appointed judicial expert conducts a contradictory assessment of the property. In Martinique, Cabinet Laurent Valère regularly serves as an expert in these procedures, thanks to its in-depth knowledge of the local real estate market since 1985.
The expert examines:
- The property's market value (probable sale price)
- Loss of enjoyment
- Replacement prejudice
- Moving and reinstallation costs
Compensation: Understanding Your Rights
Compensation Components
Compensation must be fair and prior. It includes several elements:
1. Value of the Expropriated Property
This is the market value of the property on the date of the expropriation order, calculated according to Martinique market prices. In 2026, according to DVF Martinique data:
- Fort-de-France: between €2,200 and €3,500/m² depending on neighborhoods (Didier, Bellevue, Center)
- Schoelcher: between €2,500 and €3,800/m² (Case-Pilote, Plateau Fofo)
- Le Lamentin: between €1,900 and €2,800/m²
- Southern municipalities (Sainte-Anne, Le Marin, Le François): between €2,000 and €4,500/m² depending on coastal proximity
2. Accessory Compensation
- Replacement compensation: 10% of the property value (flat rate) to cover replacement costs
- Reinstallation compensation: moving costs, utility connections, installation
- Loss of enjoyment compensation: compensation for temporary loss of use before final departure
- Professional compensation: if expropriation affects commercial or professional activity (loss of clientele, transfer costs)
3. Fees and Professional Costs
The expropriating party must also cover:
- Notarial deed fees
- Registration duties
- Attorney fees (under certain conditions)
- Expert fees if you commissioned a counter-appraisal
Martinique-Specific Considerations
In Martinique, valuation must integrate:
- Natural hazards: property in a PPRN zone may have affected value, but this must be fairly considered
- Anti-seismic and anti-cyclonic standards: recent code-compliant constructions have higher value
- Access and service: essential criterion in an island with challenging terrain
- View and location: sea view, proximity to amenities
- Local market: land scarcity in certain municipalities (Trois-Îlets, Anses-d'Arlet) strongly influences prices
Payment of Compensation
Compensation must be paid before the expropriating party takes possession of the property. In practice:
- If amicable agreement: payment after signing the notarial deed
- If judicial procedure: deposit of the proposed compensation with the Caisse des Dépôts, then payment of balance after judge's decision
Once compensation is definitively set, it bears interest at the legal rate if not paid within deadlines.
Your Legal Remedies and Defense Options
Challenging the Declaration of Public Interest
You can file an appeal for abuse of power with the Martinique administrative court within 2 months after publication of the DUP. Possible grounds:
- Absence or insufficiency of public interest
- Manifest error of appreciation
- Lack of proper public inquiry
- Disproportionate infringement on property rights
Warning: This appeal is not suspensive; the expropriation procedure continues during appeal review.
Challenging Compensation
You can:
Partial Taking: Request Total Expropriation
If expropriation only concerns part of your property and the remaining portion becomes unusable or difficult to exploit, you can request expropriation of the entirety.
Martinique example: If widening of the RN2 takes your street frontage, rendering the rest landlocked without access, you can request acquisition of the entire parcel.

Special Cases in Martinique
Expropriation and Natural Disaster Prevention
Martinique being exposed to major natural hazards (earthquakes, cyclones, landslides, tsunamis), certain expropriations aim to protect populations.
Particularly concerned municipalities:
- Prêcheur: red zone of the volcano, threat of Mount Pelée collapse
- Morne-Rouge and Fonds-Saint-Denis: recurrent landslides
- Coastal municipalities: coastline retreat, marine submersions
In these cases, compensation must account for risk-related depreciation, but also moral prejudice and attachment to place of residence.
Expropriation and Urban Renewal
Fort-de-France city center is subject to urban renewal projects sometimes involving expropriations. Issues:
- Preservation of architectural heritage
- Resident relocation
- Economic revitalization
- Anti-seismic code compliance
Expropriation of Rented Property
If your expropriated property is rented:
- The lease is terminated by law on the property transfer date
- The tenant is entitled to eviction compensation paid by the expropriating party
- You retain the right to compensation for lost rental income until the lease's normal term
How Long Does an Expropriation Procedure Take?
Timeline varies by project:
- Administrative phase (DUP + transferability order): 12 to 18 months
- Amicable phase (negotiation): 3 to 6 months
- Judicial phase (if disagreement): additional 12 to 24 months
Average total duration in Martinique: 2 to 4 years from project announcement to final compensation.
