You signed the contract, and now something feels off. Maybe a Brazilian partner told you it “won’t hold up here,” or a lawyer glanced at your document and frowned. The good news: almost every problem foreigners run into with Brazilian contracts is preventable, and most are fixable even after signing.
Here is the rule that governs everything that follows. When a contract is performed in Brazil, Brazilian law applies to it, no matter what the document says or which country’s template you used. This comes from the Lei de Introdução às Normas do Direito Brasileiro (LINDB), Brazil’s statute on the application of legal rules. Foreign investors, expats, and digital nomads arrive with English-language templates built for Common Law systems, and those templates quietly break the moment they touch Brazilian soil.
Brazil uses Civil Law (the Roman-Germanic tradition), not Common Law. The written contract, the statutory codes, and formal requirements dominate here. Judicial precedent matters far less than in the United States or the United Kingdom. That single difference is the root of the five mistakes below. Each one has a concrete fix, and the second half of this article covers the situations where the usual rule bends.

Mistake #1: Why Can’t You Price Your Contract in US Dollars or Euros?
You generally cannot use foreign currency as the primary payment method in a domestic Brazilian contract. Under Lei nº 10.192/2001, obligations payable inside Brazil must be expressed and settled in reais (BRL). A contract that requires payment in US dollars between two parties operating in Brazil can have that currency clause declared void, forcing conversion to reais at an unfavorable rate.
This surprises almost every foreigner. In your home country, pricing a lease or a service agreement in dollars is normal. In Brazil, the law protecting the national currency treats it as a matter of public order, which means the parties cannot simply agree to override it.
There are real exceptions. Import and export contracts, agreements involving parties resident abroad, and certain international financing operations may legitimately use foreign currency. The trap is the purely domestic deal: an American investor renting office space in São Paulo and insisting the rent be “USD 4,000 per month” is asking for the clause to be struck down.
In practice: Price the contract in reais, and if you want protection against currency swings, add an indexation clause tied to an official index or an exchange-rate reference. This keeps the value stable without violating the currency rule.
Real case: A foreign consultancy billed a Brazilian client “EUR 2,000 monthly” for a two-year contract. When the client stopped paying, the consultancy sued. The court accepted the debt but converted every installment to reais at the exchange rate on each due date, not the (much higher) rate at judgment. The consultancy lost roughly 18% of the expected value to that conversion.
Mistake #2: Does Your Contract Really Need to Be in Portuguese?
Yes, for any contract you might need to enforce in a Brazilian court or file with a public body. The Código de Processo Civil (Civil Procedure Code) requires all procedural documents to be in Portuguese, and Brazilian law requires a sworn translation (tradução juramentada) for foreign-language documents to produce legal effects. A sworn translation costs roughly R$ 60 to R$ 120 per lauda (a standard page of about 1,000 characters).
Many foreigners sign English-only contracts and assume they are fully enforceable. They are enforceable in principle, but the practical moment of truth is litigation. If a dispute reaches a state court (Tribunal de Justiça) or a federal court (Tribunal Regional Federal), the judge will require a Portuguese version prepared by a sworn translator officially registered with the Junta Comercial (State Commercial Registry).
The smart move is a bilingual contract with Portuguese and English in parallel columns, plus a clause naming which version prevails in case of conflict. This gives both sides a document they understand and eliminates translation disputes later. If you want the deeper mechanics of when translation and apostille are mandatory, see our guide on contract notarization in Brazil.
Heads up: A sworn translation is not the same as a good translation done by a bilingual friend. Only a tradutor público juramentado, registered with the state commercial registry, can produce a translation with legal validity for courts and public offices.
You can verify legislation directly at the official source. The full text of Brazil’s procedural rules is published by the government at planalto.gov.br (in Portuguese).
Mistake #3: Will a Brazilian Court Really Ignore Your Foreign Governing Law Clause?
Often, yes. When a contract is performed in Brazil, the LINDB says the place of performance determines the applicable law. A clause stating “this agreement is governed by the laws of New York” can be disregarded by a Brazilian judge if the obligations are carried out on Brazilian soil, especially where Brazilian public-order rules are involved.
This is the mistake that hurts sophisticated investors the most, because it feels counterintuitive. In Common Law systems, party autonomy over choice of law is nearly absolute. Brazil respects party autonomy less generously for domestic performance, and treats certain protections (consumer, labor, currency, real property) as non-negotiable.
The Other Side’s Best Argument
Here is the strongest counter-argument, stated fairly. A well-drafted contract between two commercial parties, freely negotiated, choosing foreign law and a foreign forum, should be honored: Brazil signed international conventions favoring party autonomy, and Brazilian arbitration law expressly lets parties choose the applicable rules. Why should a judge second-guess two informed businesses?
The answer: that argument is strongest precisely where it usually wins, in arbitration, and weakest in state courts handling domestic performance. Lei nº 9.307/1996, the Brazilian Arbitration Act, gives parties broad freedom to choose the substantive law governing their dispute. So if you genuinely want foreign law to control, the reliable path is not a choice-of-law clause in a court contract; it is a properly drafted arbitration clause. That is a different tool with different rules, and we explain it in our guide to the arbitration clause in Brazil.
The line, then, is this. For domestic contracts litigated in Brazilian courts, expect Brazilian law to apply regardless of the clause. For commercial contracts routed to arbitration, foreign law choices are far more likely to stand. Knowing which system your dispute will land in matters more than the wording of the clause itself. For the broader picture, read our comparison of Brazilian Civil Law versus Common Law.
Mistake #4: Which Contracts Must Be Registered at a Cartório?
Contracts transferring real property above a statutory threshold must be executed as a public deed (escritura pública) before a cartório (notary and registry office). Under the Brazilian Civil Code, a transfer of real estate valued above 30 times the highest minimum wage requires a public deed, not a private contract, to be valid. Registration at the Land Registry then makes it enforceable against third parties.
A cartório in Brazil is far more than a notary. It is a state-delegated office with legal registration powers, governed by Lei nº 8.935/1994. In Common Law countries, a signed private contract usually suffices. In Brazil, skipping notarization or registration can leave you holding a document that is valid between the two of you but powerless against a third party who registers first.
For a real estate purchase, budget beyond the price itself:
- ITBI (Property Transfer Tax): typically 2% to 3% of the property value, set by each municipality
- Escritura pública (public deed) at the cartório: cost scales with property value
- Registro de Imóveis (Land Registry) fee: roughly 1% to 1.5% of the property value
- Sworn translation of foreign documents (passport, marriage certificate) if applicable
Example: On a property priced at R$ 800,000 in São Paulo, ITBI at 3% is R$ 24,000, and the Land Registry fee at around 1.2% adds roughly R$ 9,600. Add the deed cost, and closing expenses can approach R$ 40,000 on top of the purchase price. Foreigners who budget only for the sticker price get an unpleasant surprise at the cartório.
Not every contract needs registration. Ordinary service agreements, most commercial supply contracts, and short leases can be valid as private documents. The point is to know when the formality is mandatory, because a missing escritura on a real estate deal is not a paperwork detail; it can mean you never legally owned the property.
Mistake #5: How Do Ambiguous or Badly Translated Terms Sink a Contract?
Ambiguity is expensive because Brazilian courts interpret contracts based on the written text and the Civil Code’s rules of good faith, not on the parties’ unwritten expectations. A term that means one thing in a US template can carry no equivalent under Brazilian law, and a literal translation of “best efforts,” “indemnify and hold harmless,” or “liquidated damages” often produces a clause that a Brazilian judge cannot enforce as intended.
The problem multiplies with machine or non-specialist translation. Legal English concepts frequently lack a one-to-one Portuguese counterpart. “Consideration” in the Common Law sense has no place in Brazilian contract theory. “Warranty” and “guarantee” blur into a single Portuguese word. When these terms are translated word-for-word, the resulting clause may say something the drafter never meant.
The fix is adaptation, not translation. A Brazilian contract lawyer redrafts foreign concepts into their functional Brazilian equivalents: a “liquidated damages” clause becomes a cláusula penal, a “best efforts” obligation becomes a defined obrigação de meio. This is why hiring a lawyer registered with the OAB (Brazilian Bar Association) matters more than finding the cheapest translator. Our guide on how to hire a lawyer in Brazil and avoid scams walks through the vetting steps.
Common mistake: Copying a limitation-of-liability cap from a US template. Brazilian law voids clauses that exclude liability for gross fault or bad faith. A cap that looks bulletproof in California may be partially unenforceable in Brazil, leaving you exposed exactly where you thought you were protected.
How Do These Five Mistakes Compare in Cost and Risk?
The five mistakes differ in how easily they are fixed and how much they cost if ignored. Currency and translation errors are cheap to prevent and moderately expensive to fix. Governing law and registration failures can be catastrophic, potentially voiding the deal or losing an asset. The table below summarizes the exposure based on typical scenarios.
| Mistake | Typical Consequence | Cost to Fix Beforehand |
|---|---|---|
| Foreign currency as primary payment | Currency clause voided, forced conversion at bad rate | Low (draft in BRL with indexation) |
| No Portuguese version | Sworn translation required mid-litigation, delays | R$ 60 to R$ 120 per lauda |
| Foreign governing law in court contract | Clause disregarded, Brazilian law applied | Moderate (arbitration clause drafting) |
| Missing notarization or registration | Deal unenforceable against third parties; possible loss of asset | 2% to 4.5% of property value in fees |
| Ambiguous or literal translation | Key clauses unenforceable, unexpected liability | Legal drafting fee (R$ 2,000 to R$ 15,000) |
Legal drafting fees vary widely with contract complexity and location. The figures above reflect average ranges in São Paulo and Rio de Janeiro for 2026. For a detailed breakdown, see our overview of legal costs and lawyer fees in Brazil.
What Changed for International Contracts in Brazil in 2026?
The biggest 2026 development is the full rollout of Brazil’s digital signature framework. Following implementation in 2025, contracts signed with a qualified digital certificate issued under the ICP-Brasil infrastructure now carry the same legal weight as a physically signed and notarized document for most purposes, reducing the need for in-person cartório visits.
This matters for foreigners who sign contracts remotely. A qualified ICP-Brasil signature lets you execute many agreements without flying to Brazil or chasing consular legalization for signature recognition. However, transactions that legally require a public deed (real estate above the threshold, for example) still demand the traditional cartório process. Digital signatures streamline the ordinary contract, not the deed-mandated transfer.
Note: A foreign electronic signature (DocuSign without an ICP-Brasil certificate) may still be accepted between the parties, but its evidentiary strength in a Brazilian court is weaker than a qualified certificate. When enforceability matters, use the ICP-Brasil standard or a witnessed signature.
Courts have also continued to reinforce the LINDB’s place-of-performance principle in disputes over choice-of-law clauses, confirming that the trend favoring Brazilian law for domestic performance is not weakening. If your business model relies on foreign law, arbitration remains the safer channel.
Step-by-Step: How to Draft a Contract That Holds Up in Brazil
To make a contract enforceable in Brazil, price it in reais, produce a bilingual version, adapt foreign clauses to Brazilian equivalents, respect notarization rules, and choose your dispute forum deliberately. The realistic timeline for a properly prepared commercial contract is 2 to 4 weeks, including translation and legal review.
Follow these steps:
- Confirm the currency: express the primary obligation in reais, adding an indexation clause if you want inflation or exchange protection.
- Draft bilingually: Portuguese and English in parallel, with a prevailing-version clause.
- Have an OAB-registered lawyer adapt (not translate) key clauses: penalty, liability, warranties, and termination.
- Decide the forum: Brazilian courts (Brazilian law applies) or arbitration (foreign law possible). Insert the correct clause.
- Check the formality: does this contract require reconhecimento de firma (signature recognition) or an escritura pública? Real estate and certain guarantees do.
- Sign: use an ICP-Brasil qualified certificate for remote signing, or sign at the cartório when a deed is mandatory.
- Register where required: file real property transfers at the Registro de Imóveis to bind third parties.
Documents commonly needed from a foreign party include a valid passport, a CPF (Brazilian taxpayer number), and, if signing through a representative, a procuração (power of attorney) that is itself apostilled and sworn-translated.
Tip: If you plan to do business in Brazil, get your CPF early. Almost every contract, bank account, and property registration requires it, and foreigners regularly stall deals because they left the CPF to the last minute.
If your contract is tied to opening a Brazilian company, remember that a registered address is mandatory to obtain a CNPJ (company tax ID). Ribeiro Cavalcante offers a fiscal address in Brazil for foreign founders who do not yet have physical premises.
Frequently Asked Questions
Is an English-only contract valid in Brazil?
Between the parties, yes, it can be valid. But to enforce it in a Brazilian court or file it with a public body, you will need a sworn translation (tradução juramentada) into Portuguese, produced by a translator registered with the state commercial registry. The safest approach is a bilingual contract signed from the start, with a clause naming which language version prevails if the two conflict.
Can I choose foreign law to govern my Brazilian contract?
For a contract performed in Brazil and litigated in Brazilian courts, a foreign governing-law clause is frequently disregarded, because the LINDB ties applicable law to the place of performance. Your reliable route to apply foreign law is arbitration: the Brazilian Arbitration Act (Lei nº 9.307/1996) lets parties choose the substantive rules. Choose your dispute forum deliberately, since that decision controls whether your law choice survives.
Do I need a lawyer to sign a contract in Brazil?
The law does not require a lawyer for most private contracts, but skipping one is where foreigners lose money. A US or UK template translated word-for-word often produces unenforceable clauses under Brazilian Civil Law. An OAB-registered lawyer adapts concepts like liquidated damages, warranties, and liability caps into valid Brazilian equivalents. For high-value deals or real estate, legal review is effectively essential to avoid costly surprises later.
Can a contract require payment in US dollars in Brazil?
For a purely domestic contract, no. Lei nº 10.192/2001 requires obligations payable in Brazil to be expressed in reais, and a foreign-currency payment clause can be voided and converted at an unfavorable rate. Exceptions exist for import and export, contracts with parties resident abroad, and certain international financing. If you want currency protection, price in reais with an indexation clause tied to an official reference.
How long does it take to enforce a contract in Brazilian courts?
Contract litigation in Brazil typically takes 2 to 4 years from filing to a first-instance decision, and longer with appeals, since the Brazilian court system is thorough but slow. This is a strong reason to draft well upfront and to consider an arbitration clause for commercial disputes, which is usually faster. You can read more in our guides on how long a lawsuit in Brazil takes and how to file a lawsuit as a foreigner.
Get Your Brazilian Contract Reviewed Before You Sign
Signing a contract in a legal system built on a different tradition, in a language you may not read fluently, is genuinely stressful. Every mistake above is one we have seen foreigners make, and every one is preventable with the right preparation. The difference between an enforceable deal and an expensive lesson usually comes down to a few clauses drafted correctly from the start.
