Compulsory purchase for public use: your rights and how to act

Expropriation for public utility is a phrase that alarms any property owner. When a public project arises, the law allows the State or public entities to take private property, subject to compensation.

This guide explains, in clear language, what expropriation for public use is, what your rights are, how to calculate compensation, what deadlines you cannot miss, and what steps to take to act with confidence and maximise your compensation.

Expropriation for public utility

Expropriation for public utility is the procedure through which a public entity compulsorily acquires private property to achieve a purpose of public interest, paying fair and current compensation.

The right to property is constitutionally protected, but it allows for expropriation in the public interest under the terms of Article 62 of the Constitution, provided that there is law, duly declared public utility, and adequate compensation.

In Portugal, the procedure is governed by the Expropriation Code, which establishes the phases, assessment criteria, and guarantees for individuals. By understanding the steps of expropriation for public utility, you gain control over deadlines, evidence, and negotiations.

Expropriation for public utility may occur when there is a compelling public interest that cannot be met by other means, such as the construction of essential public infrastructure (e.g., roads, hospitals, schools, public utilities) or for reasons of national security, environmental protection, or urban renewal.

Expropriation for public utility can only occur when a project serves relevant collective interests, such as road and rail infrastructure, health and education facilities, sanitation and energy networks, or urban regeneration.

The expropriating authority must demonstrate that the solution is necessary and proportionate, and that it attempted to acquire the property through amicable agreement before proceeding with expropriation for public utility.

Stages of expropriation for public utility

Before acting, it is advisable to understand the typical phases. The following introduction summarises the process, from the initial announcement to the payment of compensation.

• Declaration of public utility and urgency, where applicable. The DUP identifies the asset, the reason, and the expropriating entity.
• Attempted acquisition by friendly negotiation. A written offer should be presented based on an appraisal.
• Inspection in perpetuity for the memory of the thing, to record the state of the property, guaranteeing proof for the purposes of compensation in expropriation for public utility.
• Provisional entry into possession, if urgency is declared and the requirements are met, with deposit of the offered amount.
• Valuation arbitration, with the appointment of experts by both parties and a chairman of the arbitration tribunal, to determine the amount of compensation.
• Judicial challenge to the arbitral decision in the competent court when the owner disagrees with the amount fixed.
• Payment of compensation and records, concluding the expropriation procedure for public utility.

Compensation criteria in expropriation for public use

The compensation must be fair, current, and equivalent to the real value of the asset. A brief introduction helps to organise what counts towards the calculation.

• Market value the price a willing buyer and seller would agree on, considering location, area, condition, rents, and demand. It is the central reference in eminent domain expropriation.

• Zoning and development potential: Current use and use permitted by the municipal plan influence value. Land with development potential tends to be worth more.

• Income and occupations Lease agreements, licences, installed activities and ongoing rents come into the equation.

• Burdens and limitations: Easements, protection zones, noise, overhead power lines, and other constraints can reduce the value.

• Emerging damages and loss of profits Necessary expenses and losses directly caused by expropriation for public use may be considered, when documented.

• Relocation and replacement In own and permanent housing, there may be specific relocation support and compensation, to be agreed upon in the process.

How to act from the first contact?

Friendly or litigious expropriation

Expropriation for public utility can be concluded by amicable agreement or proceed to arbitration and court. In an amicable scenario, negotiations are based on sound valuations and clear payment and eviction clauses. In a litigious scenario, expert evidence is decisive and the procedural strategy must be defined early to protect compensation.

Evidence and documents that make a difference

A brief introduction before the list: the best defence is preparation. These elements increase your ability to prove the value of the asset in a compulsory purchase.

• Market study with recently sold comparable properties.

• Independent valuation technical report with photographs, maps and measurements.

• Proof of rent, licences and usage permits.

• Replacement assessments for affected infrastructure, accesses, and walls.

• Updated property registry and land registry certificates.

• History of works and improvements with invoices.

Common mistakes that reduce compensation

Before concluding, it is worth listing common mistakes we see in compulsory purchase orders for public utility. A brief introduction frames prevention.

• Accept the first proposal without your own evaluation.

• Ignore deadlines for response and challenge.

• Not attending the initial inspection or documenting the condition of the property.

• Devaluing existing leases and licences which increase value.

• Failure to prove replacement costs due to lack of invoices and quotes.

Quick questions about compulsory purchase

• Do I have to leave immediately when I receive the DUP? No. Leaving depends on provisional possession or a vacation agreement. Please confirm the conditions.

• Can I refuse expropriation for public utility? You can contest the grounds and values, but public utility prevails when legally declared.

• Can I keep part of the land? In some cases, it's possible to adjust routes or easements through technical negotiation. Please assess the feasibility.

How is the compensation paid?

Payment in expropriation for public utility may involve depositing the offered amount into a court account, an advance payment for Admission on possession and settlements following an arbitral or judicial decision. Interest may be charged on the amounts owed, when stipulated, from the date of possession until full payment.

Compulsory purchase for public utility and inherited property

When the expropriated asset is part of an inheritance, it is essential to align the procedure with the division of the estate. The introduction helps to avoid conflicts between heirs.

• Identify the executor of the estate and who represents the inheritance to the expropriating authority.

• Distribute compensation to heirs according to their shares, recording it in the inventory.

• Update valuations for calculation of premiums and adjustments, if part of the estate was affected by expropriation for public utility.
