When a creditor holds a final judgment from a foreign court, the work is far from over. Translating that judgment into enforceable rights against assets located in Portugal demands a formal recognition procedure – one that is procedurally precise, document-intensive, and sensitive to public policy limits that Portuguese courts apply with care.
Enforcing a foreign judgment in Portugal requires a recognition procedure known as revisão e confirmação de sentença estrangeira (review and confirmation of a foreign judgment). Conducted before the Supremo Tribunal de Justiça (Supreme Court of Portugal). The applicant must satisfy formal conditions under Portuguese civil procedure rules, including proof that the judgment is final, that due process was observed, and that recognition does not conflict with Portuguese public policy. Once confirmed, the judgment acquires the same enforceability as a domestic title.
This case study examines how the firm handled a recognition application on behalf of a Northern European corporate client, from initial diagnosis through to the issuance of an enforceable title in Portugal. The names of all parties and specific procedural details have been anonymised.
Client profile and the challenge
The client was a mid-sized manufacturing group headquartered in a Nordic jurisdiction. It had supplied specialised equipment to a Portuguese counterparty under a long-term commercial contract. A dispute arose over unpaid invoices and alleged defects. The client initiated proceedings before the courts of its home jurisdiction, where it had secured a final monetary judgment against the Portuguese company after protracted litigation.
By the time the client engaged Ferraz & Whitmore, the Portuguese counterparty had partially restructured its corporate holdings. Some assets had migrated to related entities. The client's primary concern was two-fold: first, whether the foreign judgment could be recognised in Portugal at all; second, whether recognition could be obtained quickly enough to prevent further asset dissipation.
The challenge was genuine. The judgment had been issued in a non-EU jurisdiction. EU Regulation frameworks for automatic circulation of judgments therefore did not apply. The matter fell squarely within Portuguese civil procedure rules governing the recognition of judgments from third-country courts. That added procedural weight – and time – to the process.
A parallel concern involved the counterparty's corporate structure. Under Portuguese corporate legislation (CSC), related-party transactions between group companies are subject to specific duties and constraints. The restructuring raised questions about whether assets had been moved in a manner that could be challenged separately under insolvency-adjacent mechanisms. That analysis ran alongside the main recognition track.

Legal strategy and rationale
The team's first decision was to pursue recognition before the Supreme Court of Portugal without delay. Portuguese civil procedure rules impose no hard deadline on filing a recognition application. However, delay carries practical risk: if enforcement assets are dissipated or encumbered before a penhora (attachment order) can be registered, recovery becomes substantially harder.
The strategy had three interlocking elements. First, the team assembled the documentary file required for the recognition petition. This included a certified copy of the foreign judgment, a certified translation into Portuguese. Proof that the judgment was final and non-appealable in the originating jurisdiction. Additionally, evidence that the Portuguese defendant had been duly served in the original proceedings. Each document required authentication consistent with the requirements of the Hague Apostille system, as the originating country was a signatory.
Second, the team assessed whether the judgment contained any element that could trigger the Portuguese public policy exception. Courts in Portugal apply this exception narrowly, but they do scrutinise awards that include punitive damages components or procedural mechanisms unfamiliar to civil law tradition. The foreign judgment in this matter was a straightforward damages award. No punitive element was present. The public policy risk was assessed as low, but the petition was drafted to pre-emptively address the point.
Third, the team filed a precautionary attachment application in parallel. Obtaining interim protection while the recognition procedure was pending required demonstrating fumus boni iuris (reasonable appearance of a legal right) and periculum in mora (risk of harm from delay) before the competent first-instance court. The existence of the foreign judgment itself, though not yet confirmed, served as strong evidence of the underlying entitlement.
For clients with related corporate disputes running alongside an enforcement matter, the firm's corporate disputes practice in Portugal can coordinate both tracks simultaneously.
Key milestones and complications encountered
The recognition procedure before the Supreme Court of Portugal moved through several distinct phases. The initial petition was filed within three weeks of the client's formal instruction. The court issued a preliminary reception notice and set a deadline for the respondent to file opposition.
The respondent did contest recognition. The opposition raised two arguments. First, it alleged that service of process in the original foreign proceedings had been defective. Second, it contended that recognition would violate Portuguese public policy because the quantum of damages was disproportionate by domestic standards. Neither argument ultimately succeeded, but both required substantive written responses and added approximately four months to the timeline.
On the service point, the team produced the original service records from the foreign proceedings, certified and apostilled. The Supremo Tribunal de Justiça examined these and found that service had been effected in conformity with the applicable bilateral framework and with Portuguese procedural standards. The argument was dismissed.
On the public policy point, the court reiterated the position consistently maintained in Portuguese case law: the public policy exception is not a mechanism for reviewing the merits of a foreign judgment. It applies only where recognition would produce a result manifestly incompatible with fundamental principles of the Portuguese legal order. A compensatory damages award, even a substantial one, does not meet that threshold.
One genuinely unexpected complication arose mid-process. A translation error in one certified document – a single mistranslated term relating to the contractual clause at issue – required the filing of a corrected translation and a brief supplementary submission. This caused a delay of approximately six weeks. It underscored a practical reality: in Portuguese recognition proceedings, the quality of certified translations is not a formality. Errors have procedural consequences.
The precautionary attachment obtained at first instance remained in place throughout. When the Supreme Court issued its confirmation order, the team moved immediately to initiate enforcement proceedings before the competent execution court, converting the recognised judgment into an active enforcement title.

Transferable lessons for cross-border enforcement matters
Lesson one: Document quality determines timeline. The recognition procedure in Portugal is document-driven. Every defect – a missing apostille, an incomplete translation, an ambiguous certification – generates a procedural pause. Practitioners handling enforcement matters in Portugal consistently note that the preparation phase is where most delays originate, not the court's deliberation. Front-loading document review and investing in high-quality certified translation reduces the overall timeline materially.
Lesson two: Interim protection cannot wait for recognition. The recognition procedure takes time – typically between six and fourteen months from filing to confirmation, depending on whether opposition is filed and the court's current workload. Assets do not stand still. Filing a precautionary attachment application in parallel with the recognition petition is not a tactical option; in most contested enforcement scenarios, it is a necessity. The foreign judgment provides a strong evidential foundation for the interim application, even before it is formally confirmed.
Lesson three: The public policy exception is narrower than respondents claim. It is standard practice for respondents to invoke public policy as a ground of opposition. In the experience of practitioners handling enforcement before the Supreme Court of Portugal and the Tribunal da Relação (Court of Appeal), this argument rarely succeeds against straightforward compensatory awards. However, it must be addressed in writing with precision. A well-constructed response that anchors the argument in the court's own settled position – that the exception does not permit review of the merits – is the most effective counter. Engaging a lawyer in Portugal with specific experience in recognition proceedings is the most reliable way to manage this stage.
