(https://akreodypygwbrmmgpmsq.supabase.co/storage/v1/object/public/blog-images/posts%2F2026-09-insurance-fraud-eu.jpg) When a suspicious claim crosses borders, the investigation has to cross them too — lawfully. This guide explains how international insurance fraud investigation works in practice, what evidence can be collected in which EU member state, and how insurers and their legal teams can build a file that stands up in court. ## What is an international insurance fraud investigation? An international insurance fraud investigation is a structured inquiry into a suspicious insurance claim where the policyholder, the insured event, the assets, or key witnesses are located in more than one country. Typical triggers include staged accidents abroad, inflated medical or property claims, phantom cargo losses, and claimants who quietly move assets to another member state as soon as a claim is challenged. The investigator's job is to verify or disprove the claimed facts and to document everything in a form a court or claims committee can rely on. ## Why do cross-border cases fail without professional evidence collection? Most failed cross-border files fail for the same three reasons: evidence gathered in breach of local privacy or surveillance laws, gaps in the chain of custody, and translations or registry extracts that are not properly certified. Each EU member state regulates private investigation differently. Activity that is routine in one country can be a criminal offence in another, which is why case design must start from the law of every jurisdiction involved — not from what the investigator would like to do. ## Which evidence collection methods are lawful across the EU? ### Open-source intelligence (OSINT) Publicly available sources — corporate registries, land registers, insolvency notices, court dockets, social media and press archives — can be lawfully researched in every member state. OSINT is usually the first and most cost-effective phase, and it often resolves the case on its own. ### Registry and corporate research Company ownership, directorships, real-estate holdings and vehicle registrations can be verified through official registers, subject to each country's access rules. Properly extracted registry documents form the backbone of asset-tracing in fraud files. ### Discreet surveillance, where licensed Physical surveillance is lawful in many member states when performed by licensed professionals in public places and in a proportionate manner. It is heavily restricted in others. Surveillance is only deployed where local law permits and where the expected evidential value justifies it. ### Witness statements and field interviews Interviews with witnesses, former employees, business partners or neighbours frequently produce the decisive detail. Statements are documented in writing, dated, and signed where local practice allows. ## How is cross-border evidence kept admissible? Admissibility is protected by process, not luck. Every item of evidence is logged with its source, date, collector and method; digital material is preserved with hashes; original documents are certified or apostilled where required; and personal data is handled strictly within GDPR and the legitimate-interest balancing test that applies to insurance fraud investigation under EU data-protection law. The result is a file in which each exhibit can be traced from collection to courtroom without gaps. ## How long does an international insurance fraud investigation take? A focused single-country verification typically takes one to three weeks. Multi-jurisdiction cases involving asset tracing or coordinated field work generally run four to twelve weeks, depending on the number of countries, registry response times and whether surveillance is required. ## Frequently asked questions ### Can a private investigator gather evidence in another EU country? Yes, provided the investigator respects the licensing, privacy and surveillance laws of that specific country. Experienced agencies work through vetted local partners where direct activity would be restricted. ### Is evidence collected abroad admissible in Czech courts? Generally yes, if it was obtained lawfully in the country of collection and is properly documented and, where necessary, officially translated. Czech courts assess foreign evidence under the same legality and proportionality principles as domestic evidence. ### What does an insurer receive at the end of an investigation? A structured investigation report in English (with certified translations if needed), a complete exhibit set with chain-of-custody records, and a clear assessment of the claim with recommendations for the claims decision or litigation strategy. **Exero Group investigates insurance fraud across the European Union from Prague.** If you are handling a suspicious cross-border claim, contact us for a free, confidential consultation (https://exerogroup.cz/contact) — we will tell you within days what can realistically be proven, where, and how.
