International legal due diligence: what buyers actually miss
In cross-border deals, buyers most often miss change-of-control clauses in local contracts, unregistered IP in the target's markets, misclassified contractors, undocumented related-party dealings, and permits that are not transferable. These issues rarely appear in the data room without a local lawyer asking for them.
Key takeaways
- Scope due diligence by risk value, not by document count.
- Local counsel should draft the request list, not just review it.
- Permits and licences are frequently non-transferable in an asset deal.
- Findings must convert into price, warranties or conditions — or they are wasted.
Scope before you start reading
Agree materiality thresholds, the review period and the jurisdictions in scope in writing. Unlimited scope produces a long report and a late deal; risk-weighted scope produces decisions.
The five recurring blind spots
Each of these has closed or repriced deals in practice, and each is easy to miss from a distance:
- Change-of-control clauses in key customer, lease and financing contracts
- Trade marks used but never registered in the target's actual markets
- Long-term "contractors" who meet the local test for employment
- Related-party transactions on undocumented, non-market terms
- Operating permits that cannot transfer in an asset deal
Employment and pensions deserve their own workstream
Automatic transfer rules, information and consultation duties and accrued benefit liabilities differ sharply across jurisdictions and can determine the deal structure itself, not just the price.
Turn findings into deal terms
Every material finding should end as one of four things: a price reduction, a specific indemnity, a condition precedent, or an accepted and documented risk. A finding that ends as a paragraph in a report has changed nothing.
Frequently asked questions
How long does cross-border legal due diligence take?
For a mid-market target in two or three jurisdictions, typically three to six weeks from data room access to a final report, assuming reasonably complete disclosure.
Is a red flag report enough?
For a straightforward share deal with strong warranties, often yes. For asset deals, regulated sectors or distressed targets, a full report is safer because warranty protection is weaker or the counterparty may not survive to honour it.
Who should coordinate multi-country due diligence?
One lead counsel with a single request list, a common reporting template and consistent materiality thresholds across all jurisdictions.
