The Due Diligence Mistakes That Sink Cross-Border Deals
Domestic due diligence is already complex. Add a second jurisdiction and the complexity multiplies in ways most parties do not anticipate until they are already inside the deal. Cross-border M&A due diligence is not the same process run in two countries. It requires a different approach entirely.
What Changes When a Deal Crosses Borders
In a domestic deal, both parties share the same legal framework — contract law, employment standards, tax code, regulatory environment. In a cross-border deal, that common ground disappears. What is standard practice in one country may be unenforceable in another. Diligence has to account for that gap from day one.
The Areas That Require Separate Analysis
Each of these requires jurisdiction-specific review — not just a U.S. lens applied to foreign facts:
Corporate structure and ownership. Nominee shareholders, bearer shares, and tiered structures common in certain jurisdictions raise questions about who actually owns what and whether the seller has authority to transfer it.
Employment and labor law. Many countries require mandatory severance, works council approvals, or government notifications before a deal can close. These obligations do not disappear because they were overlooked.
Intellectual property. IP ownership in cross-border companies is frequently fragmented. Contracts with foreign employees or contractors may not include enforceable assignment clauses under local law, even if they were drafted to do so.
Data privacy. GDPR, LGPD, and equivalent frameworks impose obligations on how data is handled in a transaction. Ignoring them creates regulatory exposure from the moment the deal closes.
Tax and intercompany arrangements. Service agreements, IP licenses, and intercompany loans between related entities affect both the transaction’s tax treatment and the ongoing operations of the combined business.
The Coordination Challenge
Cross-border diligence means managing legal counsel across multiple jurisdictions at the same time. Each counsel applies their own framework to the same facts. The results do not always align. Lead counsel’s job is to synthesize those inputs, identify where conflicts create real deal risk, and advise on what is manageable versus what needs to be renegotiated.
What Buyers and Sellers Should Know
Buyers — domestic diligence standards are a floor. International targets require additional layers that take more time and surface risks not visible from a single-jurisdiction view.
Sellers — unresolved structural issues, undocumented intercompany arrangements, and fragmented IP are the issues that slow deals or reduce valuations. Getting ahead of them before going to market protects both price and timeline.
