With nearly 800 licensed professionals in 2025, it is crucial to know the right questions to ask to avoid scams and ensure results that are legal and admissible. <\/p>\n<p>In this article, discover ten essential key points to review before signing with a private detective in France.<\/p>\n<p>This comprehensive guide is here to help you identify the professional best suited to your needs.<\/p>\n<\/div><\/div><div class=\"wpb_text_column us_custom_49dde2ec\"><div class=\"wpb_wrapper\"><h2 style=\"text-align: left;\"><b><span style=\"color: #69a2cd;\">1 | <\/span><\/b><span style=\"color: #002147;\">CNAPS licensing<\/span> <\/h2>\n<p>Ask the detective agency whether it is licensed.<br>\nThe National Council for Private Security Activities (<a href=\"https:\/\/www.cnaps.interieur.gouv.fr\/\" target=\"_blank\" rel=\"noopener\">CNAPS<\/a>) is the body that regulates the profession. A private detective must hold: <\/p>\n<ul>\n<li>An authorisation number (AUT) for their agency.<\/li>\n<li>A personal licence (AGD) for the director.<\/li>\n<li>A professional card (CAR) for each investigator.<\/li>\n<li>They must also have professional liability insurance covering their scope of activity.<\/li>\n<\/ul>\n<p><span style=\"color: #69a2cd;\"><strong>What you must require: <\/strong><\/span><br>\nCheck these numbers on the CNAPS website via the [DRAKAR teleservice](<a href=\"https:\/\/teleservices-cnaps.interieur.gouv.fr\/teleservices\/ihm\/#\/home\">https:\/\/teleservices-cnaps.interieur.gouv.fr\/<\/a>) and make sure these numbers are shown on quotes and contracts.<\/p>\n<h2 style=\"text-align: left;\"><span style=\"color: #69a2cd;\">2 |<\/span> <span style=\"color: #002147;\">Ask about their knowledge of the matter presented<\/span><\/h2>\n<p>A detective specialising in insurance investigations will not have the same skills as an expert in corporate fraud. Do not hesitate to ask for a detailed explanation of the measures put in place so you can understand the investigation as a whole. <\/p>\n<p>A detective agency will always be able to explain the legal aspects of its interventions. For example, in the context of <a class=\"glossaryLink\"  title=\"Lexique: Unfair competition\"  href=\"https:\/\/groupehyperion.com\/en\/lexique\/unfair-competition\/\"  data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'  tabindex='0' role='link'>unfair competition<\/a>, it can explain which evidence is admissible before the Lyon Commercial Court. <\/p>\n<h2><span style=\"color: #69a2cd;\">3 |<\/span> <span style=\"color: #002147;\">Require a detailed, transparent quote<\/span><\/h2>\n<p>Rates range between &euro;70 and &euro;150 per hour in 2025, depending on complexity and location.

Make sure it complies with the principles of <strong>legality<\/strong>, <strong>fairness<\/strong> and <strong>proportionality<\/strong> to avoid being rejected by the court.<br>\nEach jurisdiction has its own way of operating. As a result, certain pieces of evidence may be admissible in a criminal court, while being rejected by the Labour Court.  <\/p>\n<p>A private detective&rsquo;s investigation report is a document that brings together legal evidence and is tailored to your needs and to the legal strategy put in place.<\/p>\n<h2><span style=\"color: #69a2cd;\">7 |<\/span><span style=\"color: #002147;\"> A detective agency&rsquo;s physical presence in your region<\/span><\/h2>\n<p>A detective based in Paris will not master the specifics of an investigation in Montpellier or Toulouse. Give preference to professionals with: <\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Knowledge of the field (local networks, jurisdictions).<\/li>\n<li>Reasonable travel expenses.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>The strength of the Hyp&eacute;rion Group lies in systematically having an agent on site who knows the area perfectly.<br>\nThis proximity offers the best responsiveness while combining the strength of an Investigation Group with far greater resources than an isolated detective.<\/p>\n<p>For example, we may have to start our investigation in Lyon (69), continue in Annemasse (74) and ultimately have to finish in Switzerland near Geneva. Thorough knowledge of cross-border laws is required to successfully carry out this type of assignment as a whole. <\/p>\n<p>Our network is our true strength. We will always find a solution tailored to your situation. Our teams and tools are diverse, enabling us to offer a virtually unlimited range of interventions.  <\/p>\n<h2><span style=\"color: #69a2cd;\">8 |<\/span> <span style=\"color: #002147;\">Stay informed about the progress of the case<\/span><\/h2>\n<p>Request regular updates and availability to answer your questions. A good detective adjusts their strategy according to the obstacles encountered. They may need to contact you to refine an urgent decision. Each assignment is different and sometimes requires information held by the client.   <\/p>\n<p>&ldquo; <em>A relationship _intuitu personae_ (based on trust) must be established between you and the investigator<\/em> &rdquo;.<\/p>\n<h2><span style=\"color: #69a2cd;\">9 |<\/span> <span style=\"color: #002147;\">After the assignment<\/span><\/h2>\n<p>Some agencies offer legal follow-up or can put you in touch with partner lawyers. The benefit of working with a Group is ensuring the proper use of the evidence collected. We work with lawyers to refine both the needs and the strategy put in place for each case.  <\/p>\n<h2><span style=\"color: #69a2cd;\">10 |<\/span> <span style=\"color: #002147;\">What happens if the investigation fails?<\/span><\/h2>\n<p>A serious detective does not guarantee a result (obligation of means, not of result) but must explain the risks before accepting an assignment (e.g., person cannot be found, insufficient evidence).<\/p>\n<\/div><\/div><section class=\"l-section wpb_row height_small width_full\"><div class=\"l-section-h i-cf\"><div class=\"g-cols vc_row via_grid cols_1 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_text_column us_custom_99d5a672 has_text_color\"><div class=\"wpb_wrapper\"><h2>Contact Groupe Hyp&eacute;rion for any information or a free quote.<\/h2>\n<\/div><\/div><div class=\"wpb_text_column us_custom_49beb644\"><div class=\"wpb_wrapper\"><p>Please complete the form below for greater efficiency.
