The least densely populated department in France, Lozère stretches between the Cévennes, Margeride and Aubrac. Cases often require fine-tuned logistics and perfect knowledge of the terrain. Groupe Hyperion provides you with a team of CNAPS-licensed private investigators, accustomed to operating in the department to defend your rights and secure your interests. Our reports are drafted with rigor and are admissible before the civil, employment or criminal courts, provided that the evidence was obtained lawfully and with respect for privacy.
Our Services for Individuals
We support individuals in everyday disputes as well as in sensitive situations: adultery and divorce, child custody and residence arrangements, child support and revisions, abuse of weakness involving vulnerable persons, searches for missing persons or people lost to contact, asset searches (property, addresses, solvency). We combine surveillance, tailing, administrative inquiries and information gathering to produce objective, usable evidence.
Our Services for Professionals
For businesses, executives and HR departments, we conduct investigations designed to protect operations and assets: monitoring absences and prolonged sick leave, fraud and internal theft, unfair competition (client diversion, breach of a non-compete clause), employee checks (undeclared activity, unlawful multiple employment), employment tribunal investigations and, where the context justifies it, commercial infiltration. Each assignment is legally framed, proportionate and limited to what is strictly necessary.
Intervention Areas
We operate throughout the Lozère department, notably in Mende, Marvejols, Florac, Saint-Chély-d’Apcher, Langogne, La Canourgue, as well as in other municipalities in the department. Our local coverage and organisation enable us to rapidly deploy appropriate resources (two-person teams, staggered hours, inter-department relays) to ensure continuity of observation and the quality of the evidence.
Method and Compliance
Each case is subject to a prior analysis: evidentiary objectives, scope of the searches, legal constraints, observation strategy. We favour proportionate, traceable methods; the reports detail the dates, times, locations and observed facts, supported by material elements where possible. Everything is delivered in the form of a structured investigation report, directly usable.
