Entering the U. S. market creates legal blind spots because European companies often underestimate how closely ordinary operational decisions are connected to future litigation risk. Christina Lehm, a Danish-born U.S. commercial litigator and cross-border business lawyer, explains why forming a subsidiary is not enough. Contracts, governance, employment decisions, communications, data management, and insurance all influence what happens when a dispute arises—and whether the European parent company becomes involved.

European companies are accustomed to operating across borders, but the United States presents a different form of complexity. The U.S. is not one uniform legal market. Federal law applies in many areas, but individual states also regulate contracts, employment, insurance, consumer protection, corporate governance, taxation, and business registration.

A company may form its subsidiary in Delaware, maintain its principal office in Florida, employ remote personnel in California and New York, and sell products throughout the country. Each connection can create separate legal obligations.

The resulting blind spots are rarely caused by one dramatic mistake. They develop through a series of seemingly reasonable decisions:

• Using a European contract template for U.S. transactions.
• Allowing parent-company executives to approve subsidiary decisions informally.
• Hiring employees in several states under one uniform policy.
• Communicating with employees through personal devices or messaging platforms.
• Purchasing insurance without examining exclusions or notice requirements.
• Assuming that the U.S. subsidiary entirely protects the European parent.

These arrangements may work while business relationships remain positive. Their weaknesses often become visible only after an employee, customer, distributor, competitor, regulator, or business partner asserts a claim.

European groups often establish a U.S. subsidiary but continue managing important aspects of the business from Europe. This may seem efficient, particularly during the early stages of expansion when the U.S. operation has limited personnel.

The parent may negotiate contracts, approve hiring and termination decisions, control bank accounts, direct sales strategy, communicate with customers, or resolve complaints involving the subsidiary.

Parent-company oversight is not inherently improper. The risk arises when the respective roles of the parent and subsidiary are unclear.

A plaintiff may attempt to name the European parent as a defendant by alleging that it directly participated in the relevant conduct, controlled the subsidiary, made representations, assumed contractual obligations, or disregarded the subsidiary’s separate existence. Even when those arguments ultimately fail, the parent may still face demands for documents, witness testimony, jurisdictional discovery, or subpoenas.

Clear governance helps demonstrate that the subsidiary is a genuine operating entity rather than simply a name used for activities controlled elsewhere.

European companies should define who can sign contracts, hire or terminate employees, communicate with regulators, approve payments, maintain records, and instruct outside advisers. Minutes, delegations of authority, intercompany agreements, invoices, email signatures, and customer communications should accurately identify the entity involved.

Corporate separateness is not achieved by formation documents alone. It must be reflected in daily operations.

A U.S. civil case generally begins when a plaintiff files a complaint and serves it on the defendant. The complaint states the plaintiff’s allegations and requested relief; it is not a finding that the defendant did anything wrong.

Nevertheless, the complaint requires immediate attention. The response deadline may be short, and the company must quickly determine:

• Which entity or entities have been named.
• Whether service was proper.
• Whether the selected court has jurisdiction.
• Whether the case can be transferred, removed, dismissed, or sent to arbitration.
• Which insurance policies may provide coverage.
• Which employees, executives, documents, and systems are relevant.
• Whether the dispute could affect customers, regulators, lenders, or other stakeholders.

The company should promptly retain appropriate U.S. counsel and establish an internal response team. That team will often include representatives from the subsidiary, the European parent, legal, finance, human resources, information technology, risk management, and insurance.

Discovery is often the most unfamiliar and disruptive part of U.S. litigation for European businesses.

The parties may be required to exchange documents and electronically stored information, answer written questions, admit or deny factual propositions, produce witnesses for depositions, disclose experts, and obtain information from third parties.

A dispute involving a U.S. subsidiary may therefore reach information stored in Europe. Relevant materials might include:

• Emails between European executives and U.S. employees.
• Board presentations and internal reports.
• Messaging-platform communications.
• Draft contracts and negotiation records.
• Employment, compliance, and investigation files.
• Data maintained by outside vendors or cloud providers.

This can create tension between U.S. discovery obligations and European privacy, confidentiality, employment, and data-transfer requirements. Cross-border discovery should therefore be planned early. U.S. litigation counsel, European privacy advisers, and the company’s information-technology team may need to coordinate collection, review, redaction, transfer, and production.

The cost of a lawsuit is not limited to lawyers’ fees. Executives and employees may spend substantial time locating records, explaining decisions, preparing for depositions, and supporting the defense. Poor recordkeeping, decentralized communications, and widespread use of personal devices can substantially increase that burden.

Litigation readiness should begin during market entry, not after service of a complaint.

European companies can reduce avoidable risk by implementing several practical measures:

• Clarify corporate authority. Document who may enter contracts, approve employment actions, manage bank accounts, instruct counsel, and communicate for each entity.
• Adapt contracts for U.S. use. Review governing law, venue, arbitration, indemnification, limitation-of-liability, warranty, termination, insurance, and attorneys’ fees provisions.
• Create state-specific compliance processes. Do not assume that employment or commercial practices lawful in one state will work nationwide.
• Maintain disciplined records. Identify approved communication systems and establish workable retention policies before a dispute arises.
• Review insurance proactively. Understand notice requirements, exclusions, deductibles, defense-cost provisions, counsel-selection rights, and whether costs reduce policy limits.
• Test parent-subsidiary separation. Periodically examine whether contracts, approvals, invoices, branding, bank accounts, and communications reflect the intended legal structure.

These measures cannot prevent every lawsuit. They can, however, improve the company’s ability to respond quickly, protect relevant defenses, manage costs, preserve insurance coverage, and reduce the likelihood that the parent becomes unnecessarily entangled.

The most consequential U.S. litigation risks often originate long before a lawsuit is filed. They begin with the first contract, hire, customer communication, governance shortcut, or undocumented decision.

European companies should treat litigation readiness as part of market-entry planning. As U.S. operations grow across entities, states, and information systems, disciplined governance and recordkeeping will become increasingly important. Companies that prepare early are more likely to keep disputes focused, protect the European parent, and prevent litigation from disrupting the broader business.
