In the Czech Republic, the provision of private detective services is a regulated activity under Act No. 455/1991 Coll. on Trade Licensing, classified as a “concessionary trade”. To operate legally, private investigators must obtain a valid concession license from the Ministry of the Interior, demonstrating professional qualifications, integrity, and compliance with all statutory requirements. At DET.GROUP, we hold all necessary authorizations for the lawful provision of investigative services in the Czech Republic. This ensures that every investigation we conduct meets the highest legal standards, respects individual rights, and produces evidence that is admissible before Czech courts and authorities.
