Visit unfair competition is a serious threat to any business: misappropriation of customers, breach of non-competition clauses, fraudulent use of confidential information... When faced with these practices, it's essential to react quickly. But to effectively defend your interests in court, you need solid, legally admissible evidence.
This is the core business of the chartered private investigator. CNAPS Our mission: to collect tangible, documented and legally usable evidence. At Groupe Hyperion, private detectives in Montpellier, we regularly work on this type of case, whether in the Hérault region, Toulouse, Perpignan or Annecy.
What exactly is unfair competition?
Unfair competition occurs when an economic player engages in abusive behavior that causes harm to a competitor. In practical terms, this covers several situations:
- Systematic misappropriation of customers by a former employee
- Use of confidential information or stolen customer files
- Public disparagement of products or services
- Commercial parasitism (copying a visual identity or concept)
- Breach of a non-competition clause
Such conduct may be punished on the basis of thearticle 1240 of the Civil CodeIt's all about proving the facts and establishing the damage suffered. However, you need to be able to prove the facts and establish the damage suffered. This is where the private detective comes in.
Evidence that a private detective can legally collect
Surveillance and shadowing in public places
A licensed private investigator can observe and document suspicious business encounters, unusual deliveries or revealing movements. Each observation is time-stamped, geolocated and photographed. The resulting report is admissible as evidence in civil and commercial courts.
In Montpellier as elsewhere, we carry out this type of mission with discretion and professionalism.
OSINT investigations
Investigation is not limited to the field. The detective also analyses :
- Publications on professional social networks (LinkedIn, etc.)
- Competitors' websites
- Commercial announcements and press releases
- Misuse of logos, protected content or know-how
These digital searches often bring to light unfair practices that would otherwise be difficult to detect.
Targeted professional audits
Do you suspect a former employee of working for a competitor, even though he or she is subject to a non-competition clause? The detective can verify his actual professional activity, the use of customer files belonging to your company, or compliance with contractual commitments. To find out more, read our article on corporate fraud detection in Montpellier. The detective can check :
- Its actual professional activity
- Use of customer files belonging to your company
- Compliance with contractual commitments
Structured, legally usable reports
A detailed, chronological and factual report is drawn up for each assignment. It includes all the observations made, together with supporting documents (photographs, screenshots, certificates). This document can be produced in court, and serves as the basis for your legal action.
The legal framework: what a private detective can NOT do
Let's be clear: a private detective is not above the law. He acts within a strict framework:
- No intrusion into closed private or business premises
- Absolute ban on telephone tapping and computer hacking
- Respect for professional secrecy (article 226-13 of the French Penal Code)
- Obligation to hold valid CNAPS approval
At Groupe Hyperion, private detectives in Montpellier, we guarantee that every piece of evidence we collect scrupulously complies with current legislation. This is the sine qua non condition for it to be admitted by a judge.
A case study from the Hyperion Group
An SME in the Hérault region contacted us after noticing an unexplained drop in its sales. It suspected that a former sales representative, subject to a non-competition clause, was actively canvassing its long-standing customers.
In ten days of investigation, we documented several meetings between this former employee and targeted customers. The report submitted to the company's lawyer enabled us to obtain a summary order, putting a stop to the unfair practices.
As a result, the company obtained compensation and the employee was obliged to respect his contractual commitments.

FAQ - Private detective & unfair competition
No, surveillance in a person's home is an invasion of privacy. A detective can only operate in public places (streets, parking lots, restaurants) or in professional spaces accessible without intrusion. Any evidence obtained illegally would be inadmissible in court and could be used against you.
This depends on the complexity of the case. Some assignments can be resolved in a matter of days (for example, identifying suspicious sales meetings). Others require several weeks of investigation, particularly when repeated practices need to be documented or information flows analyzed. The Hyperion Group systematically draws up a transparent estimate prior to any intervention.
Yes, as long as the detective has CNAPS accreditation and the evidence has been collected in compliance with the law. Investigation reports drawn up by a certified professional are admissible evidence in civil, commercial and labor courts. Groupe Hyperion guarantees the legality of all evidence produced.
Absolutely not. The mission remains strictly confidential. The detective is bound by professional secrecy, and informing the person under surveillance would compromise the effectiveness of the investigation. Only you and your lawyer are informed of the investigation.
Rates vary according to the length of the assignment, the number of investigators involved and the complexity of the case. At Groupe Hyperion, we draw up a personalized quote after a free initial consultation. We value transparency and the absence of hidden costs.
The evidence gathered by a private detective is mainly used in civil or commercial proceedings (damages, cessation of unfair activity). If criminal facts are revealed (data theft, breach of trust), the report may be forwarded to the public prosecutor, but it is the latter who decides whether to prosecute.
No, we operate throughout the Occitanie region and beyond: Montpellier, Toulouse, Perpignan, Nîmes, as well as Annecy in the Auvergne-Rhône-Alpes region. Depending on requirements, we can also mobilize our national network for multi-site surveys.
Once you have submitted the report, you can forward it to your lawyer, who will include it in your legal file. You can then initiate summary proceedings (to put a stop to the abuse as a matter of urgency) or an action on the merits to obtain damages. Groupe Hyperion can also testify in court if necessary.
