Visiopole Investigations conducts confidential unfair competition investigations in France for companies, executives and law firms. Our Paris-based private investigation agency helps establish facts involving client diversion, competing activities, former employees, misuse of business information, breaches of contractual obligations and other suspected acts affecting legitimate commercial interests.
A private investigation can help establish whether a former employee, business partner or competitor is carrying out activities that may be relevant to an unfair competition claim. Depending on the case, investigations may combine corporate research, OSINT, field enquiries and surveillance, within the limits of French law.
Investigating Unfair Competition in France
Suspected unfair competition can place a company in a difficult position. Management may observe lost clients, unexplained transfers of business, the creation of a competing company or unusual activity by a current or former employee, without yet having sufficient factual information to determine what is happening.
An investigation can help move the matter from suspicion to verifiable facts. The objective is not to determine the legal outcome of a dispute, but to identify and document information that the company and its lawyers can assess.
For wider business investigations, see our corporate investigations in France service. Matters specifically involving a current employee can also be addressed through our employee investigations in France service.
What Can an Unfair Competition Investigation Cover?
Client Diversion
Investigation of suspected diversion of clients, prospects or commercial opportunities to a competitor, former employee or newly created business.
Competing Business Activity
Verification of professional or commercial activity carried out through another company or structure where that activity may be relevant to a business dispute.
Former Employee Activity
Fact-finding concerning a former employee suspected of developing a competing activity, approaching clients or acting in breach of continuing contractual obligations.
Non-Compete Breaches
Investigation of factual circumstances potentially relevant to a valid non-compete clause, including professional activity and involvement with a competing business.
Misuse of Business Information
Investigation of circumstances suggesting that confidential commercial information, customer knowledge or business resources may be used for competing purposes.
Corporate Connections
Research into companies, directors, shareholders, addresses and business relationships that may reveal links relevant to the suspected competing activity.
From Commercial Suspicion to Documented Facts
A sudden loss of clients or the appearance of a new competitor does not, by itself, prove unfair competition. A structured investigation can help identify who is involved, what activity is taking place and which factual elements may be relevant to legal counsel.

Client Diversion Investigations
Client diversion is a common concern in commercial disputes. A company may discover that established clients have suddenly moved to a competitor, that a former employee is approaching the same customer base, or that business opportunities are being redirected to another entity.
The key question is not simply whether clients have changed supplier. Businesses are generally free to compete. The investigation therefore seeks to establish the factual circumstances surrounding the suspected diversion.
Depending on the matter, relevant facts may include the creation of a new business, professional relationships between individuals, observed activity, corporate connections and other elements that counsel can place within the applicable legal framework.
Former Employees and Competing Businesses
A former employee may legitimately establish or join a competing company unless contractual or legal restrictions apply. The existence of competition alone is therefore not sufficient to establish wrongdoing.
Concerns may become more significant where the former employee is suspected of breaching contractual obligations, using protected business information, diverting clients or engaging in conduct that may constitute unfair competition.
A private investigator can establish factual information concerning professional activity, companies, business locations, relationships and other relevant circumstances. Legal counsel can then determine the significance of those facts.
Investigating a Suspected Non-Compete Breach
Non-compete disputes require particular care. Before investigating an alleged breach, counsel should determine whether the clause is applicable and potentially enforceable under French law.
Once the legal issue has been assessed, an investigation can focus on the facts: whether the person appears to be carrying out a relevant professional activity, the company involved, the location of that activity and other circumstances connected with the suspected breach.
Corporate Research and Hidden Business Connections
Competing activities are not always conducted directly in the name of the person at the centre of the dispute. Companies, business partners, associates or other structures may need to be examined to understand the commercial relationships involved.
Corporate research may identify management positions, companies, registered addresses, historical changes and relationships between individuals and legal entities.
These findings can be combined with OSINT and field investigation where further verification is necessary.
OSINT in Unfair Competition Investigations
Open-source intelligence can reveal valuable information about competing businesses and professional relationships. Corporate registers, professional websites, archived pages, public announcements and other lawful online sources may provide relevant leads.
However, online information must be interpreted carefully. A social-media connection, shared address or professional relationship does not automatically prove unfair conduct.
Our role is to cross-check information from different sources and distinguish verified facts from assumptions.
Surveillance and Field Investigation
Where documentary research cannot establish what is occurring in practice, field investigation may be considered. Surveillance can sometimes help verify professional activity, business locations, meetings or other circumstances directly relevant to the investigation.
Any surveillance measure must have a legitimate objective and remain necessary and proportionate. The investigative strategy is therefore defined according to the specific facts that need to be established.
We do not use unlawful intrusion, hacking or other prohibited methods to obtain evidence.
Preserving Evidence for Commercial Litigation
When the objective is potential litigation, obtaining information is only part of the process. The way in which relevant facts are documented can also be important.
An investigation report may contain observations, photographs, corporate research, OSINT findings and a chronology of relevant events. Counsel can use this information to assess whether additional evidential measures are required.
In appropriate cases, investigative findings can help counsel identify the facts or locations that should subsequently be documented through a commissaire de justice or addressed through another authorised legal procedure. Coordinating these professionals early can strengthen the overall evidential strategy.
Unfair Competition Investigations for International Law Firms
An international law firm may represent a company involved in a dispute with a French competitor, subsidiary, former employee, distributor or business partner. Local factual enquiries may then be required in France.
Visiopole Investigations can receive instructions from foreign counsel, conduct the agreed investigation in France and provide findings in English. This allows the foreign legal team to work with a regulated local investigative partner while retaining control of the overall litigation strategy.
For more information, see our dedicated service for international law firms requiring investigations in France .
Unfair Competition and Asset Investigations
Some commercial disputes also involve questions concerning companies, business structures or assets. For example, a claimant may need to understand whether commercial activity has been transferred to another company or whether relevant economic interests can be identified.
Where the objectives extend beyond establishing competing activity, our asset investigations in France service can complement the unfair competition investigation.

Before an assignment begins, the legitimate interest, investigative objective and proposed measures are assessed. The methods used must remain connected to the purpose of the investigation and proportionate to the circumstances.

Investigation Reports for Unfair Competition Cases
The report is designed to provide a factual record rather than a legal conclusion. Depending on the investigation, it may include corporate information, OSINT research, observations, photographs, relevant locations and a chronology of events.
Reports can be provided in English for foreign companies and international law firms.
Where further formal evidence is required, counsel can use the investigative findings to determine whether additional legal or evidential measures should be taken.
How Much Does an Unfair Competition Investigation Cost?
The cost depends on the facts that need to be established, the number of people or companies involved, the geographical area and whether the case requires documentary research, OSINT, field enquiries or surveillance.

|---|---|
| Corporate / OSINT research | Quotation according to scope and complexity |
| Competing activity verification | Quotation according to the investigative measures required |

Frequently Asked Questions About Unfair Competition Investigations
Can a private investigator investigate unfair competition in France?
Yes. A private investigator may conduct factual enquiries concerning suspected unfair competition where the client has a legitimate interest and the methods used comply with French law and remain proportionate.
Can you investigate a former employee who has joined a competitor?
Potentially, where specific conduct affecting the former employer's legitimate interests needs to be established. Joining a competitor is not itself proof of wrongdoing, so the investigation must focus on relevant factual issues.
Can you prove that clients are being diverted?
An investigation may establish factual elements concerning business activity, relationships, approaches to clients or other relevant circumstances. Whether those facts legally constitute unlawful client diversion is a matter for legal counsel.
Can you investigate a breach of a non-compete clause?
Yes, factual circumstances concerning suspected competing activity may be investigated. The validity, scope and enforceability of the non-compete clause should be assessed by a lawyer.
Can surveillance be used in an unfair competition case?
Surveillance may be appropriate in certain cases when it serves a legitimate investigative objective and remains necessary and proportionate to the facts being established.
Can a commissaire de justice be involved?
Yes. Depending on the case and legal strategy, investigative findings may help identify facts that should subsequently be formally documented by a commissaire de justice or addressed through another authorised legal procedure.
Do you work with foreign companies and law firms?
Yes. Visiopole Investigations conducts investigations in France for international companies and law firms, with communication and reporting available in English.
