Top 5 Challenges in Cross-Border Investigations—and How Leading Legal Teams Are Overcoming Them

Solving Global Complexity with Precision, Speed, and Strategic Insight 

Cross-border investigations are now a fact of life for U.S. companies. Whether triggered by regulatory inquiries, whistleblower complaints, or internal reviews, these matters often require handling data, people, and legal standards across multiple jurisdictions. 

But with that global scope comes risk. Each new country introduces different data privacy laws, legal privilege standards, and rules for cross-border data transfer. And without the right approach, companies can quickly find themselves exposed—to reputational harm, regulatory sanctions, or costly missteps. 

At Lineal, we work with legal teams navigating these exact challenges. What separates success from failure is no longer just legal knowledge—it’s operational precision, regional expertise, and the ability to move with confidence across borders. 

Here are the top five challenges we see—and how smarter strategies, powered by AI and legal expertise, are redefining how cross-border investigations get done.

1. Data Privacy and Sovereignty Regulations

In cross-border matters, data privacy isn’t a consideration—it’s a constraint. Regulations like the GDPR in Europe, PIPL in China, and LGPD in Brazil impose strict rules on how data can be collected, processed, and moved. In some cases, data can’t even leave the jurisdiction without explicit approval. 

For U.S. companies used to a more flexible approach, this can create friction and delay. Attempting to move personal data out of region without proper safeguards can lead to regulatory blowback or jeopardize the admissibility of evidence. 

What works:

Lineal deploys region-specific workflows, in-jurisdiction processing environments, and early legal consultation to ensure data is handled lawfully from day one. With our global footprint, investigations remain compliant, defensible, and on pace.

2. Preserving Legal Privilege Across Jurisdictions

Legal privilege is foundational to U.S. investigations—but its application varies widely around the world. In many jurisdictions, in-house counsel communications are not privileged. Others recognize privilege only in narrow circumstances. 

Misunderstanding these nuances can lead to waived protections or the disclosure of sensitive materials. And once privilege is lost in one jurisdiction, it can unravel an entire investigation. 

What works:

Lineal integrates local counsel input into early-stage planning and uses privilege-aware review strategies, including tagging protocols and audit-ready documentation. Our workflows protect privilege without slowing review.

3. Navigating Cross-Border Data Transfers

Transferring data across borders has become one of the most regulated aspects of investigations. Countries often require legal mechanisms such as Standard Contractual Clauses (SCCs), binding corporate rules, or local data residency options. 

But beyond regulatory hurdles, there’s a strategic layer: how to move only what’s necessary, minimize exposure, and ensure chain-of-custody in a legally defensible manner. 

What works:

Amplify™, Lineal’s platform-level enhancement to RelativityOne, enables secure, scalable cross-border workflows. Our legal and technical teams implement transfer frameworks tailored to each jurisdiction—including legal agreements, encryption protocols, and minimal viable data strategies.

4. Managing Modern Data Types and Communication Platforms

Today’s investigations extend far beyond email. Evidence now lives in Slack messages, Teams chats, WhatsApp threads, cloud drives, mobile devices—even encrypted collaboration platforms. 

Traditional review approaches often struggle to normalize these sources, creating blind spots or inflated costs. Without the right tools and expertise, investigations become slower, less complete, and more expensive. 

What works:

Lineal combines digital forensics and AI-enabled data analytics to ingest, process, and prioritize modern data types. Our approach reconstructs fragmented communication chains across formats, languages, and time zones—so legal teams see the full story.

5. Controlling Investigation Costs Without Compromising Quality

Cross-border investigations are resource-intensive. Legal review, hosting, expert analysis, and regional compliance support can cause costs to spiral quickly—especially when workflows are reactive or duplicative. 

Forward-looking teams are tackling this with smarter planning and managed services. The goal: defensible outcomes without overextended budgets. 

What works:

Lineal’s managed investigation model delivers predictable outcomes with operational efficiency. We emphasize early case assessment, targeted data collection, and AI-supported triage—so review is focused and spend is justified. 

A Better Model: Lineal + Amplify™

The old model—fragmented vendors, reactive workflows, unclear accountability—can’t support the speed and complexity of modern cross-border investigations. 

Lineal offers a better way forward. Our forensic-first, strategically aligned investigation model combines: 

• Amplify™-powered RelativityOne for secure, scalable data review 
• SME-driven workflows customized by region, risk, and data type 
• Real-time visibility through the Lineal Command Center 
• Global support that ensures investigations align with both local laws and U.S. compliance expectations 

Lineal’s solutions help legal teams simplify complexity in cross-border matters. From managing multi-jurisdictional data privacy concerns to reconstructing fragmented communications across modern platforms, our technology and expertise help deliver clear insights faster. The Lineal Command Center provides real-time oversight and reporting, while our global support model ensures that investigations stay aligned with local laws and internal expectations. 

Whether you’re preparing for a regulatory inquiry, responding to internal allegations, or managing litigation risk across borders, success depends on more than legal expertise—it requires precision, speed, and confidence in your data. Lineal equips your team with insight, defensibility, and the speed to lead.
