What Italian creditors and Brazilian companies with Italian exposure need to know before the first court document crosses the Atlantic
An Italian construction company secured a payment order against a Brazilian trading firm after eighteen months of civil litigation in Verona. The judgment was final. The debtor had no assets in Italy. Every euro owed was held in Brazil. The Italian creditor's in-house counsel had never considered, at the outset, whether the judgment would actually travel. That oversight cost another two years and a six-figure sum in Brazilian legal fees before a single real was recovered.
That situation is becoming more common. Legislative Decree No. 148 of 7 August 2026, the fourth corrective measure of Italy's continuing tax reform programme, introduces new permanent establishment compliance obligations for non-resident companies with Italian operations — including Brazilian companies with Italian operations. As Italian Revenue Agency (Agenzia delle Entrate) assessments against Brazilian entities increase, some will escalate to the Italian tax courts or civil courts. Others will produce Italian judgments that a Brazilian CFO will need to assess — or contest — before the STJ. Cross-border enforcement between the two countries has moved from a specialist topic to a live risk-management question.
A foreign judgment does not execute itself in Brazil. The STJ must first declare it valid — a process called homologação de sentença estrangeira, or homologation of a foreign judgment. Once homologated, the judgment becomes enforceable through the Brazilian federal courts. The process is governed by STJ Resolution No. 9 of 4 May 2005, which sets out the documentary and substantive requirements. Your Brazilian lawyer will confirm the exact filing procedure before the STJ.
The practical starting point, before any filing in Brazil, is assembling the Italian court file in apostillated form. Since Brazil acceded to the Hague Apostille Convention in August 2016 — with apostilles issued in Brazil by the Conselho Nacional de Justiça (CNJ) — Italian court documents no longer require consular legalisation to be accepted in Brazilian proceedings. An apostille affixed by an Italian competent authority (typically the relevant Court of Appeal for judicial documents) is sufficient. This step is consistently missed. Getting the apostille wrong delays the entire STJ process by months.
The Italian judgment must also be accompanied by a certified translation into Portuguese. The translation must be prepared by a sworn translator recognised in Brazil. Allow four to six weeks for the process, depending on the length of the judgment. Budget approximately EUR 1,500 to EUR 3,000 for translation alone on a medium-complexity commercial judgment.
Under STJ Resolution No. 9/2005, the STJ will homologate an Italian judgment if five conditions are met. Your Brazilian lawyer will verify the current procedural requirements, but the substantive conditions are:
The judgment must be issued by a court of competent jurisdiction. The Italian court must have had proper jurisdiction. An Italian court ruling on a contract performed in Italy, between parties who submitted to Italian jurisdiction, will generally satisfy this. A default judgment against a Brazilian defendant who was never properly served in Brazil is more vulnerable.
The parties must have been properly summoned. Italian procedural rules require service on foreign defendants through diplomatic channels or, where applicable, under the Hague Convention on Service Abroad. Italian procedural law — specifically Articles 142 and 143 of the Italian Code of Civil Procedure (Codice di Procedura Civile) — governs international service. Shortcuts here are the single most common reason an Italian judgment fails at the STJ.
The judgment must be final. In Italian procedural law, a judgment becomes final (passato in giudicato) once all appeal periods have expired or all available appeals have been exhausted. Finality is not the same as enforceability: an Italian judgment can be provisionally enforceable before it becomes final. Sending a provisionally enforceable but non-final judgment to Brazil for homologation is a mistake — the STJ requires genuine finality.
The judgment must not violate Brazilian national sovereignty, public order or morality (ordem pública). A judgment that, for example, imposes punitive damages at a level unknown to Brazilian law, or awards a remedy contrary to Brazilian constitutional principles, may be refused on these grounds.
The judgment must not be subject to prior Brazilian jurisdiction. If Brazilian courts have exclusive jurisdiction over the subject matter, the STJ will not homologate an Italian judgment on the same dispute.
Timeline: STJ homologation proceedings typically take twelve to twenty-four months, depending on whether the respondent contests. An uncontested homologation of a straightforward commercial judgment can be completed in under twelve months. Budget for STJ filing fees plus Brazilian legal fees: your Brazilian lawyer will give current figures, but the process is not cheap. Factor this into the cost of Italian litigation from the outset.
The route runs in the opposite direction when a Brazilian court has ruled and the judgment creditor needs to enforce in Italy. Article 64 of Law No. 218 of 31 May 1995 (Italian Private International Law) governs the automatic recognition of foreign judgments in Italy. Unlike many common-law jurisdictions — where a foreign judgment must be sued upon afresh, treated essentially as a debt to be re-litigated before a domestic court will act on it — Italian law operates a system of automatic recognition. A foreign judgment is recognised in Italy without any prior domestic proceeding, provided five cumulative conditions are met.
The Italian court with jurisdiction over enforcement must verify: that the foreign court had jurisdiction by criteria consistent with Italian private international law (diritto internazionale privato); that the summons was properly served and the proceedings were not in default in violation of the defendant's rights; that the parties appeared or were properly summoned and the rules of due process were observed; that the judgment is final and binding in the jurisdiction where it was rendered; that the judgment does not conflict with a prior Italian judgment or a foreign judgment already recognised in Italy on the same matter; and that the judgment does not violate Italian ordine pubblico — the Italian public order standard, which the Italian Court of Cassation has interpreted in line with the European Convention on Human Rights and EU fundamental rights norms.
Res judicata pro veritate habetur — what has been adjudged is taken for truth. That maxim from Roman law underlies both systems, but the procedural paths to that truth differ sharply across the Atlantic. A Brazilian judgment that is final under Brazilian law (coisa julgada) will be examined against Italian procedural standards. Gaps between the two systems — particularly on default procedures and notification rules — are the most common source of Italian refusals.
If recognition is disputed, the creditor or the debtor may commence proceedings before the Italian Court of Appeal (Corte d'Appello) with territorial jurisdiction. The court does not re-examine the merits. It verifies only the five Art. 64 conditions. Appeals from the Court of Appeal go to the Italian Court of Cassation (Corte di Cassazione); Panato Law Firm advises at first instance and at the level of the Court of Appeal but is not admitted before the Court of Cassation.
Yes — and often faster than a court judgment. Both Italy and Brazil are signatories to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958). For arbitral awards, the recognition route in Italy bypasses Art. 64 entirely and runs through Articles 839 and 840 of the Italian Code of Civil Procedure. The applicant files a petition with the Court of Appeal (Corte d'Appello) of the place where enforcement is sought. The court verifies the award's authenticity, the existence of a valid arbitration agreement, and the absence of grounds for refusal under the New York Convention (primarily public order and incapacity).
In practice, Italian courts have enforced foreign arbitral awards more readily than foreign court judgments, because the New York Convention framework is well-established and the grounds for refusal are interpreted narrowly. A Brazilian arbitration award rendered under ICC or CAM-CCBC rules, with a proper apostille and certified Italian translation, has a faster path to enforcement in Italy than a Brazilian state court judgment navigating the Art. 64 gauntlet. If you are structuring a commercial contract between Italian and Brazilian parties today, an arbitration clause is worth serious consideration for this reason alone.
Before Brazil joined the Hague Apostille Convention in August 2016, authenticating an Italian court document for use in Brazilian proceedings required consular legalisation — a multi-step process involving the Italian Ministry of Foreign Affairs and the Brazilian Consulate, adding weeks and meaningful cost. That route no longer applies. An apostille affixed by the competent Italian authority (the relevant Court of Appeal for judgments) is now sufficient. The CNJ issues Brazilian apostilles for Brazilian court documents travelling to Italy.
This matters in two directions. An Italian creditor seeking STJ homologation should apostillate the Italian judgment at source, before shipping anything to Brazilian counsel. A Brazilian company contesting an Italian Revenue Agency assessment that ends in a court ruling — and then seeks to enforce or contest that ruling in Brazil — faces the same documentary requirement. The apostille is a formality, but it is a blocking formality: a non-apostillated document will not be accepted.
In our files, the most common mistake is not at the homologation stage but at the start of Italian litigation. Italian creditors commence proceedings without confirming that the Brazilian defendant was served through the correct international channel — diplomatic service under Art. 142 of the Italian Code of Civil Procedure or, where available, the Hague Service Convention. When the creditor later presents the judgment to the STJ, the service defect surfaces and the homologation fails. Verifying service method before the hearing, not after the judgment, is the single most valuable step a CFO or general counsel can take at the outset.
How long does STJ homologation of an Italian judgment take in Brazil?
An uncontested homologation typically takes between twelve and eighteen months before the STJ. A contested proceeding — where the Brazilian respondent challenges jurisdiction or service — can extend to twenty-four months or more. Your Brazilian lawyer will advise on current STJ caseload; the timeline has lengthened in recent years as cross-border commercial disputes have increased.
Does an Italian judgment need to be translated into Portuguese before filing in Brazil?
Yes. The STJ requires a certified Portuguese translation prepared by a sworn translator authorised in Brazil. The original Italian judgment must also carry an apostille issued by the competent Italian authority (the Court of Appeal of the district where the judgment was rendered). A non-apostillated judgment or an uncertified translation will be rejected on formal grounds before the STJ examines the merits.
What is the difference between a final judgment and an enforceable judgment under Italian law?
Under Italian procedural law, a judgment can be declared provisionally enforceable (provvisoriamente esecutivo) by the court — meaning enforcement can begin before all appeals are exhausted. Finality (passato in giudicato) is the separate state where no further appeal is available. Both the STJ homologation route and Italian Art. 64 recognition require a judgment that is final and binding in its country of origin, not merely provisionally enforceable. Sending a provisionally enforceable Italian judgment to Brazil for homologation before it becomes final is a procedural error that will result in refusal.
