The function of the private detective

The private investigator is the only professional legally allowed to investigate in France in the civil, commercial and administrative fields. PI is an essential partner to any person lacking evidence (individual, lawyer, private company or public institution).

Indeed, in France, the judge is not intended to collect the evidence necessary to inform his judgment and relies exclusively on the elements presented to him. It is therefore to the person who alleges to provide evidence of his remarks as specified in Article 9 of the Code of Civil Procedure: “It is incumbent upon each party to prove in accordance with the law the facts necessary for the success of its claim”.

Detective activity is defined in Article L621-1 of the Internal Security Code, which states that the job of a private investigator is to “collect, even without stating its quality or revealing the purpose of its mission, information or details intended for third parties for the defense of their interests. “

Private detectives are subject to professional confidentiality by ordinary law (Article 226-13 of the Penal Code) and their ethics in accordance with Article R631-9 of the Internal Security Code. Their investigation reports are admissible in any jurisdiction since a landmark decision dated November 7, 1962.
