Translation for Due Diligence and Mergers & Acquisitions (M&A)

In a merger and acquisition (M&A) deal, due diligence often relies on documents in several languages. A fast, reliable and confidential translation of the data room files determines the quality of the review and the security of the closing. Here is how to organise it.

The context: data room and multilingual acquisition review

In a cross-border acquisition, the buyer examines the target company through a virtual data room (VDR)that gathers hundreds, sometimes thousands of documents. When the target is Belgian and the acquirer is foreign (or the other way around), part of these files must be translated so that the legal, financial and tax advisers can carry out their acquisition review. Translation is not a mere convenience: it allows hidden risks to be identified before signing.

Which documents should be translated in a due diligence?

The scope depends on the target, but certain families of documents come up almost every time:

• Corporate documents: company articles of association, shareholders' agreements, minutes of general meetings, share registers.
• Key contracts: customer, supplier and distribution contracts, commercial leases, general terms and conditions.
• Financial documents: annual accounts, management reports, trial balances, financing agreements.
• Litigation and disputes: ongoing proceedings, judgments, formal notices.
• Intellectual property: patents, trade marks, licences, R&D contracts.
• Human resources: employment contracts of key executives, incentive plans, collective agreements.
• Compliance: authorisations, certifications, environmental and regulatory documents.

The challenges specific to M&A

Translation in a merger and acquisition context combines several constraints rarely found together elsewhere. The volumes are high and often arrive in waves, under strong time pressure: due diligence windows are measured in weeks, sometimes in days. Confidentiality is absolute: the very existence of the deal is sensitive, and every party must be covered by a non-disclosure agreement (NDA). Finally, terminological consistency is critical, because the texts mix legal and financial vocabulary that must remain homogeneous from one document to another. For the closing before a notary, certain files may require a sworn translation.

How to organise the data room translation

A smooth deal relies on a clear method. Start by prioritising the critical documents(major contracts, litigation, financing) rather than translating everything in bulk: the advisers need these first to steer the review. Set up a dedicated team of legal and financial translators who remain mobilised throughout the deal. Put in place from the outset a deal glossary listing the terms specific to the target (company names, contract titles, job titles) to ensure uniform terminology. Frame access to the files and keep a record of exchanges to preserve confidentiality.

Our tips to make the deal run smoothly

Anticipate the brief as early as possible, even before the data room is fully open: knowing the sector, the source and target languages and the estimated volume allows the team to be mobilised in advance. Send the documents in coherent batches and flag the urgent files. Clearly indicate which ones will need to be sworn for the closing, as this imposes specific timeframes and a specific process. Appoint a single point of contact on the client side to arbitrate priorities and validate terminology. This discipline avoids re-translations and saves precious time in the final negotiation phase.
