When a document exists in multiple languages, a simple translation error can alter the meaning of a clause, change the balance of a contract, or even invalidate an agreement.
But in these cases, who is responsible?
The translator? The agency? The client?
And above all, how can you prevent a linguistic error from turning into a legal risk?
Responsibility in legal translation: preventing errors and securing your multilingual contracts
A legal translation is not a simple linguistic exercise.
It affects the validity of a contract, the scope of a clause, or the liability of a party.
An error can occur at several levels:
- Poorly chosen terminology that alters the nature of an obligation (“best efforts” incorrectly translated as “obligation de résultat”[obligation to achieve a specific result]).
- An omission, whether intentional or not, of a sentence or legal reference.
- A grammatical ambiguity, exploited in the event of a dispute.
In a multilingual contract, these errors are all the more dangerous as they can lead to differences in interpretation between the versions.
A legally sound document in one language may become invalid in another.
Which version prevails in the event of a discrepancy?
This is a question that legal departments often ask themselves: if two versions of the same contract differ, which one is valid?
The answer depends on the language clause in the contract.
In the absence of specific provisions, the courts seek to determine the common intention of the parties —a lengthy, costly, and uncertain process.
Good practice: always specify the reference language in your multilingual documents.
For example:
“In case of discrepancy between versions, the English version shall prevail.”
This simple sentence avoids many disputes and protects the legal consistency of your contracts.
Who is responsible in the event of a translation error?
a) The translator or translation agency
The translator is responsible for errors related to their work: misinterpretations, omissions, and incorrect translations.
However, their responsibility is limited to the contractual framework: they are not responsible for the legal content of the text, unless they are expressly assigned to do so.
At Legal 230, every translation is carried out by a translator specializing in law and then checked by a lawyer-linguist to eliminate this risk.
b) The client or the legal department
The client may also be held liable if they have not provided the necessary information: context, internal glossary, applicable legislation.
Legal translation is a collaborative effort, not a simple technical service.
When the legal department does not approve the final version, it runs the risk of misinterpretation.
c) The parties to the contract
In international contracts, if a dispute arises, the court hearing the case will analyze the version that best reflects the common intention of the parties.
But this remains a gray area: in the event of an error, it is often the version most favorable to one of the parties that prevails.
Hence the need for supervised, documented, and traceable translation work.
The consequences of a translation error
The consequences of a poor legal translation can be serious:
- Total or partial invalidity of a contract.
- Commercial or financial breakdown.
- Prolonged and costly international litigation.
- Damage to the reputation of the company or law firm.
Example:
A French company has its terms and conditions translated into English. The translated version weakens the supplier's liability clause. In the event of a dispute, the foreign customer invokes the English version—and the protective clause becomes unenforceable.
How to prevent liability risk
a) Choose a qualified legal translator
Law is a language in its own right.
Each field (commercial, social, notarial, litigation) requires specialized translators who are trained in national legal systems.
b) Check consistency between versions
Cross-checking by a bilingual lawyer is essential to ensure that all versions have the same legal significance.
c) Formalize the process
Create a bilingual glossary approved by your in-house lawyers, and always specify the reference language in your contracts.
d) Ensuring traceability
Keep a clear history of versions and validations.
This traceability is proof of diligence in the event of a dispute.

FAQ – Legal Translation and Liability
Can a translation agency be held liable for an error?
Yes, if the error stems from a linguistic misinterpretation.
But liability depends on the contract and the level of commitment stipulated.
Who decides on the reference version of a contract?
It is up to the parties to define this in a language clause included in the contract.
In its absence, the court will decide according to the common intention of the parties.
How can discrepancies between versions be avoided?
By entrusting the translation to a team specializing in law and implementing a systematic bilingual proofreading process prior to signing.
Can a translation error render a contract null and void?
Yes. If the translated clause changes the meaning of an essential obligation or condition, the contract may be partially or totally invalidated.
How does Legal 230 limit this risk?
Thanks to dual expertise— linguistic and legal —and a quality control process tailored to each type of document (contract, terms and conditions, notarized deed, court decision).
