1. What a Cross-Border M&A Attorney Actually Does
Core Responsibilities
In a domestic deal, counsel focuses on one legal system. In an international transaction, that scope expands across multiple jurisdictions simultaneously. Typical responsibilities include:
- Structuring the deal as an asset purchase, stock purchase, or merger based on tax and liability outcomes across relevant jurisdictions
- Coordinating due diligence across foreign legal systems, accounting standards, and regulatory environments
- Identifying FDI screening obligations and managing their timelines within the deal schedule
- Negotiating representations, warranties, and indemnification terms that account for cross-border risk
- Managing closing mechanics involving multi-currency payments and simultaneous filings
How Cross-Border Deals Differ from Domestic Acquisitions
| Dimension | Domestic M&A | Cross-Border M&A |
| Regulatory review | One jurisdiction | Multiple; possible CFIUS |
| Due diligence scope | U.S. .aw standards | Foreign law, labor, accounting |
| Governing law | New York or Delaware | Negotiated; may require hybrid clauses |
| Tax structure | Federal and state | Transfer pricing, withholding, treaties |
| Timeline | Predictable | Extended by foreign review processes |
The role goes well beyond drafting agreements. Counsel manages the full transaction lifecycle, from early-stage structuring through regulatory clearance and closing.
2. Regulatory and Compliance Challenges
Cfius and National Security Review
CFIUS review applies when a foreign person acquires control of a U.S. business, or when a transaction gives foreign access to sensitive personal data, critical infrastructure, or critical technologies. The governing statute is the Foreign Investment Risk Review Modernization Act of 2018 (FIRRMA).
Parties may file a voluntary notice or, in certain cases, must submit a mandatory declaration. Completing a covered transaction without required notification can result in the deal being unwound after closing. Standard CFIUS review takes up to 45 days; a national security investigation extends that by another 45 days.
Tax Structure and Transfer Pricing
Transfer pricing becomes a primary concern once an acquisition creates affiliated entities in multiple jurisdictions. The IRS and foreign tax authorities examine whether intercompany pricing reflects arm's-length standards, and audits targeting post-acquisition structures are routine. Additional tax issues include withholding taxes on cross-border payments, applicable treaty rates, and permanent establishment risk arising from how the combined entity operates after closing.
Cross-border transactions face a layer of regulatory review that domestic deals do not. Two areas consistently create the most friction.
3. Jurisdictional Issues New York Buyers and Sellers Face
Choosing governing law
New York is a frequently chosen governing law jurisdiction for international M&A agreements because of its well-developed commercial contract case law. Under New York General Obligations Law § 5-1401, parties to commercial contracts of $250,000 or more may elect New York law regardless of where they are located. This provision makes New York an attractive choice even when neither party has a prior connection to the state.
Dispute resolution options
Parties in cross-border deals typically choose between international arbitration (under ICC, AAA/ICDR, or UNCITRAL rules) and New York court litigation. Arbitration offers neutral, enforceable awards across borders under the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. Court litigation preserves access to judicial oversight and public precedent. The choice affects enforceability, confidentiality, cost, and the availability of interim relief.
Multi-jurisdictional merger control
An international acquisition may require antitrust clearance in more than one jurisdiction. The EU, China, South Korea, and other major economies maintain mandatory pre-closing merger notification requirements with independent timelines and substantive standards. Coordinating these filings is part of managing the path to closing.
4. The Deal Process: Due Diligence through Closing
What Cross-Border Due Diligence Covers
In addition to standard legal and financial review, counsel must assess corporate structure and share transfer restrictions under foreign law, labor and employment obligations that survive the transaction, IP ownership and assignability across foreign registries, pending litigation in foreign courts, and regulatory licenses that require re-approval after a change of control.
Deal Structuring Considerations
Deal structuring in a cross-border context requires balancing tax efficiency, regulatory compliance across jurisdictions, and risk allocation. Asset purchases limit assumption of unknown liabilities but carry variable tax treatment by jurisdiction. Stock purchases simplify transfer but carry full target liability. Where outright acquisition is restricted by local law, a joint venture may be the only viable path.
Cross-border transactions demand more from the due diligence and structuring phases than domestic deals.
5. How to Select the Right Cross-Border M&A Attorney in New York
The attorney or firm you select should have verifiable experience closing international transactions, not just advising on them domestically. Key factors:
Relevant experience. Look for a track record with CFIUS filings, foreign investment reviews in deal-relevant jurisdictions, and transactions of comparable size and sector. Our firm's attorneys have handled cross-border transactions across multiple jurisdictions and can identify deal-specific regulatory exposure before it becomes a timeline problem.
International network. A cross-border deal requires local counsel in each foreign jurisdiction. The lead attorney's relationships with qualified foreign counsel directly affect due diligence quality, filing speed, and closing execution. Firms with established networks can move faster and maintain consistent communication across time zones.
Practical questions to ask before engaging:
How many cross-border transactions in this jurisdiction has the firm closed in the past three years?
Who are the firm's local counsel relationships in the target jurisdiction?
How does the firm manage CFIUS or foreign review timelines within the deal schedule?
6. Frequently Asked Questions
Does every cross-border transaction require CFIUS review?
No. CFIUS jurisdiction applies when a foreign person acquires control of a U.S. .usiness or when a transaction involves a TID U.S. .usiness (technology, infrastructure, or data) and results in certain non-controlling foreign investment. Many international transactions do not meet these thresholds.
Can parties choose New York law even if neither is based here?
Yes. Under New York General Obligations Law § 5-1401, parties to commercial contracts of $250,000 or more may elect New York as the governing law jurisdiction regardless of where the parties are located.
How long does a cross-border deal typically take to close?
It varies. Transactions requiring CFIUS review and EU merger control clearance can take six months or more from signing to closing. Timeline compression depends on how early regulatory filings are coordinated.
