Request more information → https://exerogroup.cz/services/legal Why Exero Group ## Evidence, discretion and cross-border reach. Not every investigation requires the same approach. A matrimonial concern in Brno, a corporate fraud matter in Frankfurt, a child custody dispute in Prague, and a due diligence review on a Balkan beneficial owner each demand different skills, different legal frameworks, and different field teams. What unites them is the need for evidence that is collected lawfully, documented meticulously, and delivered in a form that decision-makers can act on immediately. Exero Group s.r.o. (IČO 09022104) is a licensed Czech private detective agency, holding the regulated trade licence for private detective activity under the Czech Trade Licensing Act. Every assignment has a documented lawful purpose and a proportionality assessment before any surveillance or fieldwork begins, and evidence is gathered and recorded so that you and your advisers can rely on it. Whether evidence is admitted in proceedings is always a matter for the court. We work in English and Czech as standard. Our base is Prague and the Czech Republic, and we take on assignments elsewhere in the European Union where a matter requires it, always under EU law and GDPR. Each engagement has a named case lead who stays responsible for the file from intake to final report, and we do not take on matters we are not equipped to deliver to our own standard. ### Licensed & Lawful Evidence is collected under Czech licensing law with documented chain of custody, proportionality assessments and GDPR compliance. Reports are structured so that you and your legal advisers can decide how to use the findings. https://exerogroup.cz/services/surveillance ### Bilingual, Prague-Based English and Czech as standard, with an understanding of Czech and wider EU legal frameworks. Cross-border matters within the EU are coordinated from Prague so findings are consistent across jurisdictions. https://exerogroup.cz/services/corporate ### One Case Lead, End-to-End Each matter has a named case lead who scopes it, manages it and reports to you, so you always know who is responsible for your file from intake to final report. https://exerogroup.cz/services/legal Our approach ## Evidence-led investigations, documented with care We help private clients, law firms and businesses (https://exerogroup.cz/about) resolve sensitive matters with facts that are lawfully obtained and carefully documented. Every engagement begins with a short intake assessment, what is the lawful basis, what outcome does the client actually need, and what risks does the inquiry itself carry, before any operative, OSINT tool or forensic analyst is deployed in the field. See the full breakdown on our services overview (https://exerogroup.cz/services) and worked examples in our case studies (https://exerogroup.cz/case-studies). Exero Group s.r.o. holds the regulated trade licence for private detective activity under the Czech Trade Licensing Act and runs every assignment on a GDPR-first footing. For each file we maintain a record of processing activities, document the proportionality balancing test, and archive evidence with verified timestamps. Our reports set out what was observed and how, so that you and your legal advisers can decide how to use them. We summarised the legal framework in our whitepaper on the legality of private investigations (https://exerogroup.cz/whitepaper/legality). We work bilingually in Czech and English and routinely coordinate cross-border operations across the European Union. For multinational clients, a single point of contact in Prague means a unified quality standard across jurisdictions: the same evidence-collection protocols, the same data retention rules, the same reporting cadence. Common questions are answered in our FAQ (https://exerogroup.cz/faq); examples of our work are in our case studies (https://exerogroup.cz/case-studies). Ready to start?

Who we serve ## Who we serve and how an engagement with us begins Exero Group works with **private clients and families** on matrimonial, custody-related and personal matters (https://exerogroup.cz/services/private-investigations), where discretion and a careful, factual approach matter most. For **law firms** we build evidence packages for civil and commercial litigation, trace witnesses, serve process and run forensic analysis of digital footprints. **Corporate clients** rely on us for third-party due diligence, internal fraud investigations, background investigations on hires and partners, and intellectual property protection. Our roster also includes **private equity and M&A advisors** who need Enhanced Due Diligence (https://exerogroup.cz/services/due-diligence) on counterparties under EU AML, KYC and sanctions regimes, as well as **family offices and high-net-worth individuals** for whom we handle sensitive personal matters, asset protection and pre-employment screening of key hires. We regularly partner with the **compliance teams** of multinational corporations on internal investigations into white-collar crime, conflicts of interest and code-of-conduct breaches. Every engagement begins with a **free, confidential initial consultation**. After an NDA and engagement letter are signed, we deliver a written operational plan with budget, milestones and a clear definition of success. You receive regular interim updates throughout the inquiry and, at the end, a structured report in Czech or English with annexes, photo documentation and metadata that you and your advisers can rely on. All evidence is held in encrypted storage for the period defined in our retention policy and then irreversibly destroyed.

Before Exero Group deploys a single operative, we agree with the client on the exact evidential objective, the legal basis under Section 125 of the Czech Code of Civil Procedure and Article 6(1) GDPR, the proportionality boundary and how the findings will actually be used, whether the matter is a matrimonial concern, an employment dispute, a background check on a counterparty or an M&A due-diligence project. This step protects the client from having evidence excluded later and protects the subjects of the investigation from disproportionate intrusion into their private life. During fieldwork we operate under a documented instruction letter, a strict chain of custody, timestamped and geo-tagged recordings and secure retention of raw material. Observation is limited to publicly accessible places, with no hidden cameras in private premises, no wiretapping, no phone or account hacking and no processing of minors' data without a specific lawful basis. Open-source intelligence is treated with the same discipline: every screenshot carries its own timestamp, URL, file hash and note describing the collection method, so authenticity is easy to demonstrate. The final output is not just a report, it is a package that you, your lawyers, an internal compliance committee or a cross-border auditor can work from: a bilingual Czech and English final report, an annotated photo and video annex, a handover protocol, a GDPR proportionality assessment and a summary of the legal reasoning. Our clients, private individuals, law firms, businesses, M&A advisers and family offices, receive material they can take into a negotiation, a legal consultation or a regulatory review. This is what separates real investigative work from surveillance for its own sake: factually verified, carefully documented and practically usable findings.
