Due diligence teams spend weeks combing through financial statements, but the documents that quietly sink cross-border mergers are often the ones nobody reads as carefully: the translated versions of contracts, disclosures, and regulatory filings that both sides assume say the same thing.
Two Versions, One Deal
When a target company operates in a different language market, its key documents typically exist in a translated form for the acquiring side's review. That translation is rarely produced by the same legal team that wrote the original, which creates room for terms to shift subtly between versions.
A deal can close on a translated document that both parties believe matches the original, only for a dispute months later to reveal it never quite did.
France Adds Layers Buyers Often Miss
French commercial and labor law carries protections and obligations that do not map cleanly onto English legal concepts, particularly around employee transfer and works council consultation. A translation that smooths these terms into familiar-sounding English can leave a buyer unaware of an obligation it just inherited.
French translation services with legal and M&A experience know where these gaps typically appear and flag them rather than translating past them.
Where Deal Teams Lose Time
Large transactions generate thousands of pages of due diligence material, often under tight deadlines. Legal and financial teams reviewing translated documents need tools that keep terminology consistent across every contract, disclosure schedule, and regulatory filing in the deal room.
Wordbeam's CAT editor gives translation teams working on deal documents a shared environment where terminology stays locked across the entire document set, which matters enormously when a single defined term appears in forty different contracts.
The Cost of Finding Out Late
Disputes that trace back to a translation discrepancy rarely surface during the deal. They surface during integration, when someone on the operating side reads the original-language document for the first time and notices it does not match what leadership was told.
Reporting from the Reuters M&A desk has documented multiple cases where post-merger disputes originated in contract language that read differently once native speakers on both sides compared notes.
Regulators Read the Original, Not the Summary
Antitrust and foreign investment reviewers in the target country work from the original-language filings, not the buyer's internal translation. A summary that glosses over a regulatory obligation does not make that obligation disappear once the review begins.
Guidance from the OECD on cross-border merger review consistently notes that accurate documentation is one of the clearest factors separating smooth approvals from prolonged regulatory scrutiny.
Treating Translation as Deal Risk, Not Deal Logistics
The acquirers who avoid these problems are not the ones who translate the most documents. They are the ones who treat translation accuracy as a due diligence workstream with its own review, rather than a task handled quietly in the background.
By the time a merger closes, the paperwork should say exactly the same thing in every language it exists in. Getting there takes more than a translator with a deadline.
