Enforce Foreign Judgment Brazil 2026: STJ Guide

You won a court case in London, signed a binding arbitration award in Singapore, or have a contract governed by New York law — and now the other party has assets in Brazil. You assume you can simply present the paperwork to a Brazilian judge and start collecting. That assumption is wrong.

Brazil is a Civil Law jurisdiction, not a Common Law one. A foreign judgment, arbitral award, or contract does not automatically carry legal weight on Brazilian soil. Before any foreign decision can be enforced, it must pass through a mandatory recognition procedure called Homologação de Sentença Estrangeira (Homologation of Foreign Judgment) — and the only court in Brazil that can grant this recognition is the Superior Tribunal de Justiça (STJ), Brazil’s highest appellate court for non-constitutional matters.

This article answers the most-searched questions about enforcing foreign contracts and judgments in Brazil in 2026. You will learn exactly what the STJ requires, how much the process costs, how long it takes, and what pitfalls can derail your enforcement before it even begins. If you are an expat, investor, digital nomad, or foreign company with a Brazilian counterparty, this guide is built for you.

Essential Questions About Enforcing Foreign Contracts in Brazil

What exactly is STJ homologation and why do I need it?

STJ homologation is the legal process that transforms a foreign judicial or arbitral decision into something a Brazilian court can enforce. Without homologation, your foreign judgment is legally invisible inside Brazil. The Brazilian Federal Constitution (Article 105, I, “i”) grants the STJ exclusive jurisdiction over this procedure. No lower federal court, no state court, and no notary office can perform it. Even if both parties agree the foreign judgment is valid, the STJ must still issue a formal homologation decision before any enforcement action can begin in a first-instance federal court. Think of homologation as a legal “stamp of approval” from Brazil’s highest non-constitutional court — without it, you have nothing.

Which foreign decisions can be enforced in Brazil?

The STJ can homologate foreign court judgments, foreign arbitral awards, and certain foreign administrative decisions that are final and unappealable in their country of origin. The decision must be “final” (trânsito em julgado in the origin country) — meaning no appeals are pending. It must also not violate Brazilian ordem pública (public policy), national sovereignty, or human dignity. For example, a foreign judgment ordering specific performance of a contract will generally pass this test. A foreign judgment enforcing gambling debts or punitive damages (which Brazil largely rejects outside specific statutory exceptions) may fail. Foreign contracts themselves — without an underlying judgment or award — are not directly “homologated.” Instead, you would file a fresh lawsuit in Brazil based on the contract, a concept explained further below.

How long does the STJ homologation process take?

Realistically, expect 6 to 18 months from filing to a final STJ decision. The timeline depends on whether the defendant contests the request, whether the Ministério Público Federal (Federal Public Prosecutor’s Office) raises objections, and the STJ’s current caseload. If the defendant challenges homologation — which is limited to formal defects, not the merits of the case — the process extends closer to the 18-month mark. Uncontested cases with impeccably prepared documentation can move faster, sometimes in 4 to 6 months. Then, remember: homologation is only step one. Actual enforcement (execução) happens in a separate proceeding before a first-instance federal court, which adds more time. For a broader perspective on litigation timelines, read our guide on how long a court case takes in Brazil in 2026.

Costs and Process: What You Will Actually Pay

What are the court filing fees for STJ homologation?

The STJ charges filing fees (custas judiciais) that must be paid via a federal tax receipt (Guia de Recolhimento da União — GRU) at the time of filing. In 2026, the initial filing fee typically ranges from R$ 1,500 to R$ 3,000, depending on the nature and complexity of the request. Additional fees may apply if the STJ orders expert review or if procedural incidents arise. These amounts are updated periodically by the STJ’s internal regulations (Regimento Interno do STJ), so your lawyer should verify the current tabela de custas before filing. For context, R$ 3,000 is approximately USD 520 or EUR 480 at early 2026 exchange rates. Compared to the value of most international contracts, this is a manageable entry cost — but it is non-refundable, even if homologation is denied.

How much does sworn translation cost for foreign contracts?

Every document not in Portuguese must be translated by a Tradutor Juramentado — a sworn translator registered with a state Junta Comercial (Commercial Registry). These professionals charge per “page,” where a standard page equals 1,000 characters (including spaces). In 2026, rates vary by state but typically range from R$ 80 to R$ 150 per page. A 30-page English-language judgment could cost between R$ 2,400 and R$ 4,500 to translate. Complex legal terminology, urgent requests, or rare languages can push costs higher. Sworn translation is non-negotiable; the STJ will reject any filing with non-sworn translations, no matter how accurate they appear. Budget for this expense early — it is often the single largest disbursement in the homologation process.

What will a Brazilian lawyer charge for this process?

Legal fees for STJ homologation are set by the OAB (Ordem dos Advogados do Brasil — Brazilian Bar Association) fee schedule in each state, but are negotiable between lawyer and client. For a straightforward, uncontested homologation, expect total legal fees between R$ 15,000 and R$ 35,000. Complex cases involving multiple parties, contested proceedings, or urgent interim measures can reach R$ 60,000 or more. Some firms charge flat fees; others bill hourly. Always request a written contrato de honorários (fee agreement) that clearly states the scope of work. Be wary of quotes below R$ 8,000 for STJ-level work — the procedural requirements are exacting, and an underprepared filing can lead to dismissal with no refund of court costs. If your case also involves broader contract disputes, see our article on common contract mistakes foreigners make in Brazil to avoid compounding errors.

Special Situations and Edge Cases: Enforce foreign judgment brazil

Can I enforce a foreign arbitral award in Brazil?

Yes — and arbitration awards are often easier to homologate than court judgments. Under Lei nº 9.307/1996 (Brazilian Arbitration Act), foreign arbitral awards are enforceable through the same STJ homologation process. Brazil is also a signatory to the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, which means the STJ applies a pro-enforcement standard. In late 2025, the STJ issued new internal guidelines specifically streamlining the homologation of international arbitration awards, reducing procedural bottlenecks. The defendant’s grounds for opposition are narrower than for court judgments — typically limited to due process violations, arbitrator impartiality, or the award exceeding the arbitration agreement’s scope. If you structured your international contract with an arbitration clause, you likely have a smoother enforcement path in Brazil.

What if the foreign contract was signed digitally?

Brazil fully implemented the Sistema Brasileiro de Assinatura Digital (Brazilian Digital Signature System) in 2025. Contracts signed with ICP-Brasil certified digital signatures — the Brazilian public key infrastructure standard — are now equivalent to notarized documents for most legal purposes. If your foreign contract was signed using an ICP-Brasil certificate, the STJ will accept it without requiring additional notarization. However, if the digital signature relies on a foreign certification authority not recognized by ICP-Brasil, you will likely need to apostille the digital certificate or provide supplementary authentication. The safest approach for contracts executed abroad remains a combination: digital signature using an internationally recognized platform plus an apostille on the final executed version, ensuring seamless acceptance at the STJ. For contracts that must also be registered in Brazil — such as those involving real estate — digital-only execution may still trigger cartório (notary office) registration requirements.

Can interim measures or emergency orders be enforced?

This is where things get complicated. Foreign interim measures — such as freezing orders, preliminary injunctions, or emergency asset seizures — face significant hurdles in Brazil. The STJ’s homologation process is designed for final decisions, not provisional ones. Interim relief ordered by a foreign court generally cannot be homologated because it lacks finality. Your alternative is to file a new request for interim measures directly with a Brazilian court, using the foreign proceedings as supporting evidence. Brazilian courts can grant tutela de urgência (urgent relief) independently, including freezing Brazilian bank accounts or restricting property transfers, if you demonstrate fumus boni iuris (likelihood of success) and periculum in mora (risk of damage from delay). This strategy requires a separate filing and adds cost, but it can be effective when time is critical. For broader litigation strategy, consult our article on commercial litigation in Brazil.

What Changed in 2026 for Enforcing Foreign Contracts in Brazil?

Two significant developments affect foreign contract enforcement in 2026. First, the STJ’s late-2025 internal guidelines for international arbitration award homologation are now fully operational. These guidelines reduce redundant document requests, standardize the review criteria across STJ panels, and create a “fast track” for awards from major arbitral institutions like the ICC, LCIA, and CAM-CCBC. Practically, this means arbitration awards now move through the STJ roughly 30% faster than foreign court judgments.

Second, the ICP-Brasil digital signature equivalence — fully implemented in 2025 — is now being tested in practice. Early 2026 has seen STJ decisions affirming that contracts and awards signed with ICP-Brasil certificates do not require additional notarization, even when the signing party is abroad. This is a major cost-saver for enforcement proceedings, eliminating the need for physical notarization of signature pages. However, the system works only if the digital certificate is issued by an authority within the ICP-Brasil chain. Foreign digital certificates from non-integrated authorities still require apostille and, in some cases, consular legalization.

No changes to the core legal framework — CPC/2015 Articles 960 to 965 remain the governing statute for homologation — are currently under discussion in Congress. The Constitutional requirement of exclusive STJ jurisdiction (Article 105, I, “i”) is settled law and unlikely to change.

Step-by-Step: How to Enforce a Foreign Contract or Judgment in Brazil

Here is the practical roadmap for enforcing a foreign decision in Brazil in 2026. Follow these steps sequentially — skipping any one of them can result in STJ rejection and months of lost time.

• Step 1 — Verify Finality: Confirm that the foreign judgment or award is final and unappealable (trânsito em julgado) in the country of origin. Request a certificate of finality from the foreign court or arbitral institution.
• Step 2 — Apostille All Documents: Since Brazil joined the Hague Apostille Convention in 2016, all foreign public documents — court orders, certificates of finality, notarized contracts — must bear an apostille from the competent authority in the country of origin. Private documents may also require notarization before apostille.
• Step 3 — Sworn Translation: Hire a Tradutor Juramentado in Brazil to translate every document into Portuguese. The translator’s signature and credentials must appear on each translated page. Machine translations, even if edited, are not accepted.
• Step 4 — Hire a Brazilian Lawyer: You need a lawyer registered with the OAB who has experience with STJ filings. The lawyer will access the e-STJ electronic portal and prepare the Petição de Homologação de Sentença Estrangeira (Petition for Homologation of Foreign Judgment).
• Step 5 — Pay Court Fees: Your lawyer generates the GRU (federal payment slip) through the e-STJ system. Pay this immediately — the filing is not considered submitted until the fee clears.
• Step 6 — Service of Process on the Defendant: The STJ notifies the defendant (requerido) to respond within the period established by the RISTJ (STJ Internal Regulations). The defendant’s response is limited to formal challenges — lack of finality, improper service abroad, fraud in the foreign proceeding, or violation of Brazilian public policy. The merits of the case cannot be re-litigated.
• Step 7 — Federal Prosecutor’s Opinion: The Ministério Público Federal reviews the request and issues an opinion. The MPF primarily checks for public policy violations and formal compliance.
• Step 8 — STJ Panel Decision: A panel of STJ ministers (turma) reviews the case and issues a decision. If homologation is granted, the decision becomes res judicata in Brazil.
• Step 9 — Enforcement in First-Instance Federal Court: With the STJ homologation in hand, your lawyer files a separate execução (enforcement) proceeding in the competent first-instance federal court. This is where bank accounts are actually frozen, assets are seized, and judgments are satisfied. Homologation alone does not enforce anything — it merely unlocks the door to enforcement.

If the underlying dispute has not yet produced a judgment or award — meaning you only have a signed contract and a breach — skip directly to filing a new lawsuit in the appropriate Brazilian court. The STJ homologation process is irrelevant until you have a final foreign decision.

Frequently Asked Questions

Can a foreign court judgment be enforced directly in Brazil without STJ involvement?

No. The Brazilian Federal Constitution gives the STJ exclusive jurisdiction over foreign judgment recognition. No lower court, federal or state, can enforce a foreign judgment that has not been homologated by the STJ. This is absolute — there are no exceptions, shortcuts, or workarounds. Even if both parties consent, the STJ must still issue a formal homologation. Attempting to enforce directly in a lower court will result in immediate dismissal.

Do I need the original contract or is a certified copy enough?

The STJ requires the original foreign judgment or a certified copy issued by the foreign court, properly apostilled. A simple photocopy or scan will not suffice. If you only have the contract (not a judgment), you will file a new lawsuit in Brazil rather than seek homologation, and the contract itself becomes the core evidence. In that scenario, having the original signed contract — or a digitally signed version with ICP-Brasil certification — is critical. Lost originals should be reconstructed through notarized copies from the foreign counterparty or court archives.

What happens if the other party does not respond to the STJ citation?

If the defendant fails to respond after proper service of process, the STJ proceeds with the homologation review anyway. The defendant’s silence does not automatically result in homologation — the STJ still verifies all formal requirements. However, an uncontested proceeding moves significantly faster because there are no defense briefs to analyze and no procedural disputes to resolve. The defendant also loses the opportunity to raise formal objections at the homologation stage, though they can still challenge enforcement later in the first-instance execution proceeding on limited grounds.

Can I enforce a foreign contract that was never notarized?

It depends on the contract’s governing law and the type of enforcement sought. If you are filing a new lawsuit in Brazil based on the contract (not seeking homologation of a judgment), Brazilian courts will assess the contract’s validity under its governing law. Many common law jurisdictions do not require notarization for contract validity, and Brazilian courts respect this. However, certain contracts — such as those transferring Brazilian real estate — must be registered with a Brazilian cartório regardless of foreign formalities. A foreign contract lacking notarization may face heightened evidentiary scrutiny but is not automatically invalid.

Is mediation or arbitration faster than STJ homologation?

Arbitration is significantly faster and more predictable than full litigation followed by STJ homologation. A foreign arbitral award from a recognized institution takes 4 to 12 months to homologate under the STJ’s 2025 streamlined guidelines. Mediation, by contrast, does not produce a binding decision — a mediated settlement is a contract, not an award. If the settlement is breached, you would need to sue on the settlement agreement in Brazil or seek arbitration (if the settlement includes an arbitration clause). For international contracts with Brazilian parties, an arbitration clause — specifying a seat outside Brazil if preferred — is almost always the most enforcement-friendly structure. Learn more in our guide to governing law and dispute resolution in Brazil.

What if my country does not have a reciprocal enforcement treaty with Brazil?

Brazil does not require a bilateral treaty for foreign judgment homologation. The STJ will review judgments from any country, provided they meet the formal requirements of CPC/2015 Articles 960-965. There is no requirement of reciprocity (unlike some civil law jurisdictions). However, the foreign judgment must come from a court with proper jurisdiction over the matter, the defendant must have been properly served, and the decision must not violate Brazilian public policy. A judgment from a country with a weak judicial system may face greater scrutiny, but treaty absence alone is not a barrier.
