Legal due diligence in cross-border M&A

Short answer

Cross-border due diligence is harder because the same clause can mean different things under different laws. The main risk is not volume. It is uneven depth: some jurisdictions get a thorough review, others a light one.

Why is cross-border due diligence harder?

A target with subsidiaries in several countries brings:

  • Documents in several languages
  • Contracts under different governing laws
  • Local registers, filings and regulators
  • Several law firms, each with its own way of working

Every extra jurisdiction adds review work and coordination work.

Why is it not just a volume problem?

Because legal meaning changes at the border. A few examples of areas where local law often makes the difference:

  • Change of control: whether a clause triggers on an indirect transfer, and what consent is needed.
  • Employment: notice periods, works council rights and transfer rules.
  • Restrictive covenants: whether a non-compete is enforceable at all.
  • Data protection: local rules on top of, or outside, the GDPR.

The same wording can be harmless in one country and a deal issue in another. A review that ignores the governing law will miss it.

Where does depth tend to drop?

Usually in the jurisdictions that matter least by revenue. They get less time, a smaller team or a lighter template. Material issues can sit exactly there.

Other common gaps:

  • Findings reported in different formats per country, which makes them hard to compare
  • Documents in a third language that nobody reads in full
  • Late documents that never reach the local reviewer

What does good cross-border due diligence look like?

  • One scope, applied to every jurisdiction
  • Review logic that fits the governing law of each document
  • One report format, so findings can be compared and ranked
  • Every finding linked to its source
  • Clear flags where a local lawyer needs to confirm a point

Can AI help in cross-border reviews?

Yes, if it is built on the law of each jurisdiction. AI can read every document in every language and apply the same depth everywhere. It cannot replace the local lawyer's judgment on a contested point.

FAQ

Is reading a foreign-language contract enough?

No. Translation tells you what the clause says. Local law tells you what it means.

Should each jurisdiction have its own report?

Use one report with one structure. Group findings by jurisdiction inside it.

Who signs off on local points?

A lawyer qualified in that jurisdiction.
