Governing Law Brazil Contracts: What Actually Works

Yes, you can choose New York, English, Swiss or Portuguese law to govern a contract with a Brazilian counterparty. But the clause that actually delivers that choice is almost never the clause people write, and the reason has nothing to do with how well it is drafted.

Here is the scenario we see every month. A European supplier signs a three-year distribution agreement with a Brazilian company. The contract was drafted by a competent London or Lisbon firm. Clause 22 says the agreement is governed by the laws of England and Wales. Both sides sign at a meeting in São Paulo. Two years later the Brazilian distributor stops paying, sues in a state court in Brazil for “abusive termination”, and the judge applies Brazilian law to the entire dispute. The English law clause is mentioned in a single line of the decision and then set aside.

Nobody did anything wrong in the negotiation. The right was lost at signature, in a detail nobody discussed: where the contract was legally formed. Brazil is a Civil Law country, and its conflict-of-laws statute dates from 1942. It contains no express party autonomy rule for court litigation. That single gap is why so many foreign companies discover, years later, that the law they paid to be governed by was never going to apply.

This article starts with the rule, then spends the second half on the situations where the rule does not apply, which is exactly where your protection lives.

What Is the Actual Rule on Governing Law for Contracts Involving Brazil?

Under Article 9 of Decreto-Lei 4.657/1942, Brazil’s Law of Introduction to Brazilian Legal Norms (LINDB), obligations are governed by the law of the country where the contract was formed, not by the law the parties selected. There is no express party autonomy provision for litigation. A Brazilian judge can lawfully ignore your foreign law clause.

This is the principle Civil Law systems call lex loci contractus, the law of the place of formation. The full text of the statute is published on the Planalto federal government portal. Three provisions matter most:

• Article 9, caput: the law of the place of formation governs the obligation. Sign in Brazil, and Brazilian law applies by default.
• Article 9, paragraph 1: obligations to be performed in Brazil that require a special form must follow Brazilian formal requirements. Foreign law never overrides Brazilian formalities.
• Article 17: foreign law, acts and judgments produce no effect in Brazil when they offend national sovereignty, public order or good morals.

Compare this with the European Union, where the Rome I Regulation protects party choice as a starting point, or with the United States, where courts generally enforce a reasonable choice of law. Brazil never enacted an equivalent. The 1942 statute was drafted when cross-border contracting was rare, and it was never modernized for court litigation.

Why Do So Many Foreigners Lose This Right Without Knowing It?

Because the right is lost by a factual detail, not by a legal error. Under Article 9 of the LINDB, the place of contract formation decides the applicable law, and most foreign parties sign in Brazil during a closing meeting or a site visit. That single fact can convert a carefully drafted foreign law clause into decoration.

There are four recurring causes, and none of them look like mistakes at the time:

• The closing happens in Brazil. Investors fly to São Paulo or Recife, sign on the table, and the place of formation becomes Brazil.
• The contract is a translated foreign template. It copies a governing law clause written for a system that honours party autonomy, so nobody questions whether it works here.
• Nobody chooses a dispute resolution mechanism that supports the choice. The parties pick foreign law but leave disputes with “the competent courts”, which in practice means a Brazilian state court.
• The counterparty’s lawyer knows the rule and says nothing. Silence costs the Brazilian side nothing and buys an enormous home-field advantage if a dispute arises.

The result is predictable. By the time anyone reads Article 9 of the LINDB, the dispute already exists and the signature page already says “São Paulo”. You are then litigating under Brazilian law, in Portuguese, in a system where, according to data published by the National Council of Justice, first-instance commercial cases commonly take years to reach judgment. Our overview of how long Brazilian court cases actually take sets realistic expectations.

How Does the Place of Formation Rule Decide Your Case?

Article 9, paragraph 2 of the LINDB provides that a contract concluded between absent parties is deemed formed at the domicile of the offeror. In cross-border deals signed by email or courier, this means the party that formally makes the offer determines the place of formation, and therefore the default governing law.

This is the most underused provision in Brazilian private international law. It is not a loophole; it is the statute itself. If the foreign party is the proponente (offeror) and sends the binding offer from Frankfurt, Miami or Lisbon, the contract is deemed formed abroad. A foreign governing law clause then rests on the statutory rule rather than fighting against it.

Practical example: A Dutch technology company licenses software to a Brazilian retailer for R$ 200,000 per year. Version A: both parties sign in São Paulo, and the contract names Dutch law. Version B: the Dutch entity sends a signed, binding offer from Amsterdam by email; the Brazilian company countersigns in Brazil and returns it. In Version B the place of formation is the Netherlands under Article 9, paragraph 2, and the Dutch law clause has a statutory foundation. Same commercial deal, radically different litigation position.

Three drafting details make the difference:

• The document must be structured as an offer and acceptance, not as a jointly executed instrument signed in one room.
• The preamble should state expressly that the offer was issued from the foreign party’s domicile and accepted by return communication.
• Keep the email trail. The formation chain is evidence, and you will need it years later.

Isn’t Party Autonomy a Global Standard? The Strongest Argument Against the Brazilian Rule

The best counter-argument is genuinely strong: Brazil ratified the New York Convention in 2002 and the Brazilian Arbitration Act expressly allows parties to choose the applicable law, so the legal system plainly accepts party autonomy. On that reading, Article 9 of the LINDB is an outdated default rule, not a prohibition.

Let me state that argument at full strength, because the other side will. Brazil is a party to the Vienna Convention on Contracts for the International Sale of Goods (CISG), in force domestically since 2014, which itself contemplates party choice. Article 2, paragraph 1 of Lei 9.307/1996 lets arbitrating parties pick any substantive law. Brazilian legal scholarship overwhelmingly defends party autonomy in international contracts. And Article 9 of the LINDB never says a choice of law is void; it simply provides a connecting factor. A sophisticated advocate will argue that the clause should be read as the parties’ lawful exercise of contractual freedom under the Civil Code.

That argument is intellectually correct and it sometimes wins. Here is why you cannot rely on it. Brazil is a Civil Law jurisdiction without binding precedent for ordinary commercial decisions, so the position of one court does not bind the next. Judges in state civil courts handle thousands of cases and apply the clear text of Article 9 as written. Scholarly consensus is persuasive authority, not controlling law. In practice, you are betting six or seven figures on one judge’s willingness to prefer doctrine over statutory text. The superior courts, whose decisions you can search on the Superior Court of Justice (STJ) portal, are far more receptive to party autonomy than first-instance courts, but reaching them takes years.

So the argument is real. It is just the wrong thing to build a contract on, when the statute gives you something better.

Where the Rule Stops Applying: Why Is Arbitration the Only Reliable Route?

Article 2, paragraph 1 of Lei 9.307/1996, the Brazilian Arbitration Act, expressly authorizes the parties to choose the rules of law applicable to the arbitration. This is the only place in Brazilian law where party autonomy over governing law is written in black and white. A valid arbitration clause converts your choice of law from an argument into a right.

You can read the statute on the Planalto portal. Two features make it decisive:

• The arbitrator must apply the chosen law. No conflict-of-laws detour through Article 9 of the LINDB.
• A valid arbitration clause removes the dispute from the courts. If your counterparty files suit in Brazil anyway, you raise the arbitration clause and the court must decline jurisdiction on the merits.

There is a further point most foreign parties miss. If the arbitration is seated in Brazil (for example São Paulo, under the rules of an institution such as CAM-CCBC or CAM-B3), the resulting award is a domestic award. It is enforceable directly in Brazilian courts as an enforceable instrument, with no need to homologate it at the STJ. If the arbitration is seated abroad, the award is foreign and must first be recognized by the STJ, a process that typically adds a year or more.

Arbitration has a real cost. Institutional and arbitrator fees in Brazil are typically calculated on the amount in dispute, and for a claim around R$ 2,000,000 the combined costs published in institutional fee tables can run well into six figures in reais, payable up front. That is why the structure must match the deal size, which the table below addresses. For a broader comparison of the forums available, see our analysis of when foreign law actually applies in Brazil.

Court, Brazil-Seated Arbitration or Foreign-Seated Arbitration: Which Route Fits Your Deal?

For contracts below roughly R$ 350,000 in value, arbitration is usually uneconomic and Brazilian court litigation under Brazilian law is the realistic path. Above that range, arbitration seated in Brazil generally offers the best combination of party autonomy, enforceability and speed, with awards enforceable without STJ recognition.

Factor	Brazilian state court	Arbitration seated in Brazil	Arbitration seated abroad
Is your chosen foreign law applied?	Uncertain. Article 9 LINDB default applies	Yes. Lei 9.307/1996, Art. 2, para. 1	Yes
Typical time to a final decision	2-4 years to first judgment, plus appeals	12-24 months	12-24 months plus STJ recognition
Enforcement in Brazil	Direct	Direct, domestic award	Requires STJ homologation
Indicative cost exposure	Court fees plus loser-pays attorney fees of 10-20% under Art. 85 CPC	Institutional and arbitrator fees from roughly R$ 80,000 upwards on mid-size claims	Often higher, plus translation and recognition costs
Language of proceedings	Portuguese only	Any language the parties choose	Any language the parties choose
Best suited to	Claims under R$ 350,000	Deals with assets or counterparty in Brazil	Deals where neither side has Brazilian assets

One number deserves attention. Under Article 85 of the Brazilian Civil Procedure Code, the losing party pays the winner’s attorney fees, normally fixed at 10% to 20% of the value of the claim. On a R$ 200,000 dispute that is R$ 20,000 to R$ 40,000 on top of your own legal spend. We break the arithmetic down in our guide to legal costs and the loser-pays rule in Brazil.

Where Even Arbitration Cannot Save Your Chosen Law?

Article 17 of the LINDB bars any foreign law, act or judgment that offends Brazilian sovereignty, public order or good morals. Arbitration protects your choice of law, but it cannot override Brazil’s mandatory rules. Some subject matters are governed by Brazilian law regardless of what the contract says or where it was signed.

These are the recurring red zones:

• Employment relationships. Brazilian labour protections apply to work performed in Brazil. Labour claims are also not arbitrable in the same way as commercial claims.
• Consumer contracts. The Consumer Protection Code is mandatory public policy. A foreign law clause in a B2C contract with Brazilian consumers will not displace it.
• Real property located in Brazil. Rights over Brazilian real estate are governed by Brazilian law and depend on registration at the competent real estate registry.
• Currency. Payment obligations performed in Brazil must generally be denominated in reais under Brazilian monetary rules enforced in the framework supervised by the Central Bank of Brazil. Pricing in dollars is possible in genuinely international transactions, but not as a free choice.
• Form requirements. Article 9, paragraph 1 of the LINDB keeps Brazilian formalities in place: notarisation at a cartório (notary office with legal registration powers), witness signatures, registration where required.
• Corporate and insolvency matters. The internal affairs of a Brazilian company and any bankruptcy proceeding follow Brazilian law. Which is one reason the company type you choose in Brazil matters as much as the contract wrapped around it.

There is also a practical limit that has nothing to do with Article 17. For a R$ 150,000 supply contract, an arbitration clause can be worse than useless: the cost of starting arbitration may exceed the claim, leaving you with a right you cannot afford to exercise. In those deals, accept Brazilian law and Brazilian courts, and invest the drafting effort in security instead: advance payment, bank guarantee, retention of title, or a promissory note signed by the company’s partners.

What Changed in 2026 for Governing Law in Brazilian Contracts?

No statutory change to the LINDB’s conflict-of-laws rules took effect for 2026. Article 9 of Decreto-Lei 4.657/1942 remains in force exactly as written in 1942. Three practical developments do matter: fully digital court proceedings, a pending legislative proposal to modernize private international law, and consolidated STJ practice on recognizing foreign decisions.

Digital proceedings. The judiciary’s Juízo 100% Digital programme, coordinated by the National Council of Justice, has matured to the point where a foreign party can litigate or enforce in Brazil with hearings by videoconference and fully electronic filings. You still need a Brazilian lawyer registered with the OAB (Brazilian Bar Association) and a power of attorney, but physical presence is now rarely required.

Reform proposal. A legislative proposal to modernize Brazil’s private international law rules, including an express party autonomy provision for international contracts, continues to move through Congress. If enacted, it would align Brazil with the Rome I approach. It is not law today, and drafting as if it were is a serious mistake.

Recognition practice. The STJ remains the exclusive forum for recognizing foreign judgments and foreign arbitral awards. Its internal rules require a certified copy of the decision, proof of proper service on the Brazilian party, an apostille under the Hague Convention, and a sworn translation into Portuguese. The practical lesson is unchanged: a Brazil-seated award avoids this stage altogether.

Step-by-Step: How Do You Build a Governing Law Clause That Actually Works in Brazil?

A workable structure has five parts: an arbitration clause that satisfies Lei 9.307/1996, a seat chosen by where the assets are, an explicit governing law clause, documented place of formation under Article 9, paragraph 2 of the LINDB, and compliance with Brazilian formalities. Omit any one of them and you are back to arguing.

Step 1: Decide whether arbitration is economically viable

Compare the realistic dispute value against institutional fees. Below roughly R$ 350,000, consider Brazilian law plus Brazilian courts plus strong payment security. Above it, arbitration usually pays for itself in the first dispute avoided.

Step 2: Choose the seat by following the assets

If the counterparty’s money, inventory or real estate is in Brazil, seat the arbitration in Brazil and keep your foreign substantive law. If neither side has Brazilian assets, a foreign seat is fine.

Step 3: Draft both clauses explicitly, naming the institution

Name the arbitral institution, the number of arbitrators, the seat, the language and the governing substantive law. Vague wording such as “arbitration in accordance with applicable rules” invites a challenge to the clause itself, which is litigated in a Brazilian court.

Step 4: Document the place of formation

Where possible, structure the signature as an offer issued from abroad and accepted by the Brazilian party. State this in the recitals. Preserve the email chain. This is your fallback if the arbitration clause is ever held defective.

Step 5: Handle the paperwork before you need it

• Bilingual Portuguese and English contract with a prevailing-language clause.
• Sworn translation (tradução juramentada) for anything that may be filed in court, typically charged per page and billed from around R$ 80 to R$ 150 per page by sworn translators registered with the commercial registry.
• Apostille on foreign corporate documents and powers of attorney, under the Hague Apostille Convention applied in Brazil through the National Council of Justice.
• Brazilian tax identification: CNPJ for a company, CPF for an individual. A blocked or irregular CPF will stall a filing, as explained in our guide to fixing an irregular CPF status.
• Signature authority check: confirm in the company’s articles of association who can bind the Brazilian entity.

Frequently Asked Questions About Governing Law in Brazilian Contracts

Can I simply write “governed by the laws of New York” in a contract with a Brazilian company?

You can write it, and it is not illegal. But if the dispute reaches a Brazilian court, the judge applies Article 9 of the LINDB and may hold that the law of the place of formation governs instead. If the contract was signed in Brazil, that is Brazilian law. The clause becomes reliable only when paired with a valid arbitration clause under Lei 9.307/1996, which expressly permits the parties to choose the applicable substantive law.

Does a foreign court judgment work in Brazil if I win abroad?

Only after recognition. A foreign judgment produces no effect in Brazil until the Superior Court of Justice (STJ) homologates it. You must file a certified copy of the judgment, proof that the Brazilian party was properly served, an apostille and a sworn translation into Portuguese. Uncontested cases can conclude in under a year; contested ones take longer. Only after homologation can you start enforcement against Brazilian assets, which is itself a separate proceeding.

Is an arbitration clause enforceable against a Brazilian company that refuses to arbitrate?

Yes. Under the Brazilian Arbitration Act, a valid arbitration clause binds both parties and ousts the jurisdiction of the courts over the merits. If the Brazilian party files suit anyway, your lawyer raises the clause in the defence and the court should dismiss the case. The arbitration can also proceed without the reluctant party’s cooperation, since institutional rules allow the tribunal to be constituted and the award issued in default.

Does the contract have to be in Portuguese?

Not for validity between the parties. But any document filed with a Brazilian court or registered at a cartório must be accompanied by a sworn translation into Portuguese prepared by a publicly appointed translator. The practical solution is a bilingual contract with a prevailing-language clause stating which version controls. That avoids translation disputes later and removes a common delay at the filing stage.

Can I choose foreign law for the sale of property located in Brazil?

No. Rights over real property located in Brazil are governed by Brazilian law, and transfer of ownership only occurs upon registration of the deed at the competent real estate registry office. A foreign law clause will not change the formalities, the registration requirement or the tax treatment. You can choose foreign law for ancillary obligations between the parties, but not for the property rights themselves.

Get Your Governing Law Clause for Brazil Reviewed Before You Sign

Most of the foreign companies that lose this right never made a bad decision. They signed a good contract in the wrong room, with a clause written for a different legal system. The gap between a clause that works in Brazil and one that does not is usually three paragraphs and one afternoon of review.
