A Pyrenean department bordering Andorra, Ariège alternates between rural areas, mountain villages, and cross-border routes. This geography shapes diverse investigation needs, ranging from family disputes to checks related to professional activity and assets. Groupe Hyperion provides you with a team of CNAPS-approved private investigators, accustomed to operating in the department to defend your rights and secure your interests. Our reports are meticulously drafted and are admissible before civil, labor, or criminal courts, provided that evidence has been obtained lawfully and with respect for privacy.
Our assignments for individuals
We assist individuals with daily disputes as well as sensitive situations: adultery and divorce, child custody and residence arrangements, alimony and revisions, abuse of vulnerable persons, searches for missing persons or those out of touch, and asset searches (property, addresses, solvency). We combine surveillance, shadowing, administrative inquiries, and information gathering to produce objective and actionable evidence.
Our assignments for professionals
For businesses, executives, and HR departments, we conduct investigations aimed at protecting activity and assets: monitoring absences and extended sick leave, internal fraud and theft, unfair competition (diversion of clientele, non-compliance with a non-compete clause), employee monitoring (undeclared activity, illicit multiple employment), labor court investigations, and, when the context justifies it, commercial infiltration. Each mission is legally framed, proportionate, and limited to what is strictly necessary.
Areas of operation
We operate throughout the Ariège department, particularly in Foix, Pamiers, Saint-Girons, Lavelanet, Saverdun, Mazères, Mirepoix, Tarascon-sur-Ariège, as well as in other municipalities of the department. Our local network and organization allow us to quickly deploy appropriate resources (teams of two, staggered hours, inter-departmental relays) to ensure continuous observation and the quality of evidence.
Method and compliance
Each case undergoes a preliminary analysis: evidence objectives, scope of research, legal constraints, observation strategy. We prioritize proportionate and traceable methods; reports detail dates, times, locations, and observed facts, supported by material evidence when possible. The entire package is submitted as a structured, directly usable investigation report.
