Expropiación Forzosa en España: Requisitos, Justiprecio y Procedimiento (2026)

# Compulsory Expropriation in Spain: Requirements, Just Compensation, and Procedure (2026)

Compulsory expropriation is the coercive deprivation of property or rights on grounds of public utility or social interest, in exchange for compensation. It is governed by the Ley de Expropiación Forzosa (LEF (Compulsory Expropriation Act) of 16 December 1954 and its implementing Reglamento (REF (Regulation) of 1957, instruments that, despite their age, remain in force with periodic amendments.

1. Constitutional and Legal Basis

Article 33.3 of the Spanish Constitution guarantees that no one may be deprived of their property except on grounds of public utility or social interest, upon payment of the corresponding compensation and in accordance with the law. The LEF gives effect to this mandate.

Cumulative requirements (Art. 1 LEF):

1. Public utility or social interest ground: declared by statute or determined by the Administration with statutory authorisation
2. Prior compensation: the just compensation (justiprecio) must be established before occupation, except in cases of urgency
3. Legally established procedure: minimum procedural guarantees

2. Parties to the Expropriation

• Expropriating authority: the State, Autonomous Communities (Comunidades Autónomas), Local Authorities, and bodies authorised by law
• Beneficiary: the expropriating authority or other entities (concessionaires, developers) to whom the property is transferred
• Expropriated party: the holder of the affected property or right (owner, tenant, usufructuary, holder of rights in rem)

3. General Procedure (Arts. 15–58 LEF)

Phase 1: Declaration of Public Utility or Social Interest

The causa expropiandi (legal justification for expropriation) may be implicit in statute (public works of general interest: roads, railways, hydraulic works) or may require an express declaration by the Council of Ministers (Consejo de Ministros) or the relevant regional government body (Consejería autonómica).

Phase 2: Declaration of Necessity for Occupation (Arts. 15–22 LEF)

The expropriating Administration draws up a schedule of property and rights required. A public information period of 20 days is opened, objections are resolved, and the definitive schedule is approved. Once notified to the expropriated party, this triggers the process for determining the just compensation.

Phase 3: Determination of Just Compensation: Justiprecio (Arts. 23–47 LEF)

Amicable agreement (Art. 24 LEF): The Administration and the expropriated party may agree on the just compensation by mutual consent. If no agreement is reached within 15 days, the matter is referred to the Provincial Expropriation Jury.

Valuation offers (Hojas de aprecio) (Arts. 29–30 LEF):

• The Administration submits its valuation offer
• The expropriated party has 20 days to accept it or submit their own valuation
• If there is a discrepancy, the file is referred to the Provincial Expropriation Jury

Jurado Provincial de Expropiación (Provincial Expropriation Jury) (Arts. 32–35 LEF):

• A collegiate body chaired by a magistrate of the Audiencia Provincial (Provincial Court of Appeal)
• Issues its decisión within 8 days (a period not strictly observed in practice)
• Decisión is binding but may be challenged before the administrative courts (jurisdicción contencioso-administrativa)

Phase 4: Payment and Occupation (Arts. 48–58 LEF)

• Once the just compensation is determined, the Administration must pay it within 6 months
• If payment is not made within that period, default interest accrues (Art. 56 LEF): the just compensation is increased by the applicable legal interest rate
• Default interest accruing between the declaration of urgency and actual payment can be substantial in projects subject to prolonged delays

Receipt and Deed of Occupation

Upon payment of the just compensation, an acta de ocupación (deed of occupation) is executed, which serves as the instrument of acquisition of the property and may be registered in the Registro de la Propiedad (Land Registry).

4. Urgent Procedure (Art. 52 LEF)

This procedure allows immediate occupation prior to the determination of just compensation, subject to:

1. A declaration of urgent occupation by the Council of Ministers or the equivalent regional body
2. Execution of a preliminary deed of occupation (acta previa de ocupación)
3. A prior provisional deposit: an amount estimated by the Administration plus an additional 5%

The just compensation is determined subsequently. Default interest (Art. 56 LEF) runs from the preliminary deed of occupation until actual payment.

5. Valuation: Just Compensation Criteria

The LEF establishes different criteria depending on the type of property:

Immovable property: land value per unit of buildable area (urban land) or corrected cadastral value plus the state of any works. The Ley del Suelo (TRLS 2015: Consolidated Land Act, Arts. 34–40) sets out specific valuation methods for planning land.

Principal criteria (TRLS 2015):

• Rural land: capitalisation of actual or potential income using discount rates set by regulation
• Developed urban land: static or dynamic residual method depending on the stage of development

Plant, machinery, and stock: depreciated replacement value

Rights: specific valuation according to their nature (leases, easements, concessions)

Disturbance allowance (Premio de afección) (Art. 47 LEF): a 5% uplift on the total just compensation in recognition of the hardship caused by the deprivation

6. Reassessment and Right of Reversion

Reassessment (Retasación) (Art. 58 LEF): If 2 years elapse from the determination of just compensation without commencement of the works or operation for which the expropriation was carried out, the expropriated party may request a reassessment of the property at current values.

Right of reversion (Arts. 54–55 LEF): If the expropriated property is not used for the purpose that justified the expropriation, the original owner has the right to recover it upon payment of the updated just compensation. Time limit: 20 years from the Administration's acquisition.

7. Challenging the Just Compensation

Administrative challenges:

• Against the decisión of the Provincial Expropriation Jury: an appeal (recurso de alzada) or reconsideration (reposición) before the expropriating Administration (depending on the nature of the body)

Administrative court proceedings:

• Judicial review (recurso contencioso-administrativo) before the TSJ (Tribunal Superior de Justicia: High Court of Justice of the Autonomous Community) challenging the Jury's valuation
• Time limit: 2 months from notification or publication of the Jury's decisión
• The TSJ courts have exclusive jurisdiction in expropriation matters

Common grounds for challenge:

• Incorrect valuation of land (inappropriate method applied)
• Failure to include compensable heads of loss (relocation costs, loss of business goodwill)
• Default interest not calculated or undervalued
• Rights of tenants not taken into account

8. Relevant Supreme Court Case Law

STS (Supreme Court judgment) 15 January 2020 (appeal no. 3400/2018): consolidates the dynamic residual method for unsectored developable land, rejecting the capitalisation of agricultural rents where proven development potential exists.

STS 12 March 2021 (appeal no. 1234/2019): on the valuation date in the urgent procedure; the value is fixed as at the date of the preliminary deed of occupation, not the date of the Jury's decisión.

STS 8 June 2022 (appeal no. 4567/2020): the 5% disturbance allowance (premio de afección) is applied to the total just compensation, including default interest.

9. Sector-Specific Expropriations

Urban planning expropriations: in addition to the LEF, regional land legislation applies. Voluntary management agreements (equitable redistribution of land (reparcelación voluntaria)) are an alternative to expropriation.

Transport infrastructure expropriations: the Ley de Carreteras (Roads Act) and the Ley del Sector Ferroviario (Railway Sector Act) establish specific procedures for linear infrastructure works, with an implicit declaration of urgency in many cases.

Environmental expropriations: Protected Natural Areas (Ley 42/2007) may give rise to compensation obligations even without formal expropriation where a significant limitation of rights occurs.

10. Practical Considerations for Lawyers

Checklist:

• Is there a valid declaration of public utility or social interest?
• Have all holders of rights over the property been properly notified?
• Does the period between the declaration and occupation comply with the statutory limits?
• Does the Administration's valuation offer cover all compensable heads of loss?
• Has default interest been calculated from the correct date?
• Is there a right of reversion to be claimed due to change of purpose?

Documentation to gather:

• Title deed and Land Registry history
• Up-to-date cadastral certificate
• Independent technical valuation report
• Evidence of rental income where affected tenancies exist
• Relocation/reinstatement budget where a business activity is involved
