How to translate a contract into English: complete guide
Translating a contract into English demands absolute precision. A single mistranslation can alter contractual obligations, render clauses unenforceable, or expose your business to significant legal risk. Whether you are finalising an international partnership, closing an acquisition, or drafting a service agreement, the quality of the translation matters just as much as the content of the contract itself.
Common mistakes in contract translation
Legal translation is full of pitfalls that generic tools simply cannot avoid. These are the most frequent errors:
False cognates — The Portuguese word "eventual" means "possible", but in English "eventual" means "final" or "inevitable". This difference can completely change the meaning of a clause.
Inconsistent terminology — In a contract, the same concept must always use the same term. If "prestador de serviços" appears as "service provider" in one clause and "contractor" in another, it creates legal ambiguity that can be exploited in disputes.
Literal translation of fixed expressions — Phrases like "sem prejuízo de" cannot be translated word for word. The correct form is "without prejudice to" or "notwithstanding", depending on context.
Ignoring differences between legal systems — Portuguese law (civil law) and Anglo-Saxon law (common law) use fundamentally different concepts. A "escritura pública" (public deed) has no direct equivalent in common law jurisdictions — it requires adaptation, not just translation.
Essential legal terminology
Anyone working with contracts across languages should be familiar with these key terms:
- Whereas — introduces the recitals, setting out context and intent
- Hereinafter — defines shorthand references for the parties
- Indemnify and hold harmless — obligation to compensate and protect from liability
- Force majeure — kept in French even in English-language contracts
- Governing law — specifies which jurisdiction's law applies to the contract
- Severability — ensures that an invalid clause does not void the entire agreement
- Non-disclosure / Confidentiality — protects sensitive information shared between parties
- Breach of contract — failure to fulfil contractual obligations
