How to Get a Foreign Court Decision Recognized in Portugal

How to Get a Foreign Court Decision Recognized in Portugal: A Complete Guide

Whether you have a divorce decree from Brazil, a child custody order from the United States, a property judgment from the United Kingdom, or any other foreign court decision, you cannot simply present it to Portuguese authorities and expect it to be enforced. Foreign court decisions must first go through a formal recognition process in Portugal before they carry legal weight.

This guide explains the entire process — from legal foundations to practical steps — so you know exactly what to expect.

The Legal Framework: Why Recognition Is Necessary

The principle of state sovereignty means that each country’s courts have authority only within their own territory. A judgment from a Brazilian, American, or British court has no automatic legal force in Portugal. To bridge this gap, Portuguese law provides a mechanism called revisão e confirmação de sentença estrangeira — literally, the review and confirmation of a foreign judgment.

This process is governed by Articles 978 to 985 of the Portuguese Code of Civil Procedure (CPC). It is not a retrial or appeal. The Portuguese court does not re-examine the merits of the original case. Instead, it conducts a formal review to ensure the foreign judgment meets certain procedural and substantive standards.

International Agreements That May Apply

Before diving into the standard process, it is worth noting that certain international agreements can modify or simplify the recognition procedure:

EU Regulation 1215/2012 (Brussels I Recast): Judgments from EU member states benefit from a simplified recognition regime. In many cases, they are recognized automatically without a special procedure.
EU Regulation 2201/2003 (Brussels II bis): Applies specifically to matrimonial matters and parental responsibility within the EU.
Hague Convention on the Recognition of Divorces (1970): Facilitates recognition of divorce decrees among signatory states.
Bilateral treaties: Portugal has bilateral judicial cooperation treaties with several countries, including Brazil (Tratado de Auxílio Judiciário em Matéria Civil). These can simplify certain aspects of the process.

For judgments from non-EU countries without applicable treaties — or when treaty conditions are not met — the standard CPC procedure applies.

Which Court Handles the Recognition?

Recognition petitions are filed at the Tribunal da Relação (Court of Appeal). Portugal has five Courts of Appeal:

Tribunal da Relação de Lisboa
Tribunal da Relação do Porto
Tribunal da Relação de Coimbra
Tribunal da Relação de Évora
Tribunal da Relação de Guimarães

Jurisdiction is determined by the applicant’s domicile in Portugal, or by the place where the judgment needs to produce effects. For most expats living in the Lisbon area, the Tribunal da Relação de Lisboa handles the case. Learn more about the role of the Courts of Appeal in foreign judgment review.

The Six Requirements for Recognition (Article 980 CPC)

Article 980 of the CPC sets out the conditions that the Portuguese court verifies. All six must be satisfied:

1. Authenticity of the Document

The foreign judgment must be authentic — meaning there are no doubts about whether it is a genuine document issued by the competent authority. This is established through proper certification, apostille, or consular legalization.

2. Finality (Res Judicata)

The judgment must be final and binding under the law of the country where it was issued. It must no longer be subject to ordinary appeal. You will typically need a certificate confirming finality from the originating court or authority.

3. Jurisdiction of the Foreign Court

The court that issued the judgment must have had proper jurisdiction under the rules of the country where the case was decided. Additionally, the case must not fall within the exclusive jurisdiction of Portuguese courts. For example, matters involving Portuguese real property generally fall under exclusive Portuguese jurisdiction.

4. Due Process (Proper Service and Right to Defense)

Both parties must have been properly served and given the opportunity to participate in the proceedings. If the losing party was not properly notified or was denied the right to present a defense, recognition will be refused. This is one of the most common grounds for refusal.

5. Compatibility with Portuguese Public Policy

The foreign judgment’s outcome must not be manifestly incompatible with the fundamental principles of the Portuguese legal order (ordem pública). This is a high bar — minor differences in law are tolerated. Only judgments that violate core values (e.g., discriminatory provisions, denial of fundamental rights) are refused on this ground.

6. No Conflicting Portuguese Judgment

There must not be an existing Portuguese judgment on the same matter between the same parties. If a Portuguese court has already decided the issue, the foreign judgment cannot override it.

Step-by-Step Process

Step 1: Document Preparation

This is arguably the most important phase. Gather and prepare all required documents:

certified duplicate of the foreign judgment
Certificate of finality (transit in rem judicatam)
Proof of proper service on the opposing party
Apostille or consular legalization on all documents
Certified translation into Portuguese by a sworn translator
Identification documents of the parties
Power of attorney for your Portuguese lawyer

Step 2: Legal Analysis

Before filing, your lawyer should conduct a thorough analysis of the foreign judgment against the six requirements of Article 980. This identifies potential weaknesses and allows for preemptive measures — such as obtaining additional documentation or preparing legal arguments to address foreseeable objections.

Step 3: Filing the Petition

The petition (requerimento) is filed at the competent Tribunal da Relação, accompanied by all supporting documents and proof of payment of court charges. The petition must identify both parties, describe the foreign judgment, and argue that all recognition requirements are met.

Step 4: Service on the Opposing Party

The court serves the opposing party (the respondent), who then has a period — typically 15 days if served in Portugal, or longer if served abroad — to file a response. If the respondent does not contest, the case proceeds as uncontested.

Step 5: Prosecution’s Opinion

The Ministério Público (Public Prosecutor) is always heard in recognition proceedings. The prosecutor issues an opinion on whether the requirements are met. This is a formality in most cases but can raise issues the parties did not address.

Step 6: Court Decision

The panel of judges at the Court of Appeal reviews the case and issues a decision (acórdão). In straightforward, uncontested cases, this is typically a confirmation. In contested cases, the court may hold a hearing before deciding.

Step 7: Registration (When Applicable)

Certain recognized judgments — particularly divorces and custody orders — must be registered with the Portuguese civil registry (Conservatória dos Registos Centrais) to produce their full effects.

How Long Does It Take?

Realistic timelines for 2026:

Document preparation: 2–6 weeks (depends on how quickly you can obtain documents from abroad)
Uncontested recognition: 4–8 months from filing
Contested recognition: 10–18 months from filing
Registration after recognition: 2–4 weeks

Types of Foreign Decisions Commonly Recognized in Portugal

The process applies to a wide range of court decisions:

Divorce decrees — the most common type (see our specific guide on Brazilian divorce recognition)
Child custody and visitation orders — subject to additional considerations under the Hague Convention on child custody
Alimony and maintenance orders
Property division judgments
Adoption decrees
Criminal sentences (in certain circumstances, under separate legislation)
Commercial judgments (breach of contract, debt collection, etc.)

Common Reasons for Refusal

While most well-prepared cases succeed, recognition is occasionally refused. The most common reasons are:

Defective service of process: The respondent was not properly notified of the foreign proceedings. This is especially common in default judgments.
Lack of finality: The judgment is still subject to appeal in the originating country.
Public policy violation: Rare, but can occur with judgments involving punitive damages (which Portuguese law does not recognize) or provisions that discriminate on prohibited grounds.
Exclusive Portuguese jurisdiction: The matter falls within the exclusive competence of Portuguese courts.

Frequently Asked Questions

Can I handle the recognition process myself, without a lawyer?

Technically, Portuguese law does not always require legal representation for this type of proceeding. However, given that the process takes place at the Court of Appeal, involves complex procedural and private international law questions, and requires drafting legal petitions in Portuguese, self-representation is strongly discouraged. The cost of hiring a experienced lawyer is a worthwhile investment.

What if the opposing party cannot be found?

If the respondent’s location is unknown, the court may authorize service by public notice (citação edital). This involves publishing a notice in official channels and waiting a specified period. It adds time to the process but does not make recognition impossible.

Does the foreign judgment need to be from a country that has a treaty with Portugal?

No. Portugal recognizes foreign judgments from any country, provided they meet the requirements of Article 980 CPC. Treaties and EU regulations may simplify the process, but their absence does not prevent recognition.

Can arbitral awards be recognized through this process?

No. Arbitral awards follow a different recognition regime, primarily governed by the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958) and Portuguese Law 63/2011 (the Portuguese Arbitration Law). The procedure is similar but involves different courts and legal standards.

What happens if my recognition petition is refused?

You can appeal the refusal to the Supremo Tribunal de Justiça (Supreme Court of Justice), Portugal’s highest court for civil matters. However, it is far better to ensure your initial petition is thoroughly prepared to avoid this scenario.
