At the confluence of the Garonne and the Tarn, this agricultural and logistics-focused department concentrates numerous commercial exchanges and sensitive HR issues. 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 rigorously and are admissible before the civil, labour or criminal courts, provided that the evidence was obtained lawfully and with respect for privacy.
Our assignments for individuals
We support individuals in everyday disputes as well as 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 follow-up, asset searches (property, addresses, solvency). We combine surveillance, tailing, administrative investigations and information gathering to produce objective, usable evidence.
Our assignments for professionals
For companies, executives and HR departments, we conduct investigations designed to protect business activity and assets: monitoring absences and extended sick leave, fraud and internal theft, unfair competition (poaching clients, breach of a non-compete clause), employee checks (undeclared activity, unlawful multiple employment), labour court investigations and, where the context justifies it, commercial infiltration. Each assignment is legally framed, proportionate and limited to what is strictly necessary.
Areas of operation
We operate throughout the Tarn-et-Garonne department, notably in Montauban, Castelsarrasin, Moissac, Montech, Caussade, Valence d’Agen, as well as in other municipalities in the department. Our local coverage and organisation enable us to quickly 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 means; the reports detail the dates, times, locations and observed facts, supported by material evidence where possible. Everything is delivered in the form of a structured investigation report, directly usable.
