HYPERION GROUP
Private detectives for individuals are not reserved solely for adultery investigations. As a citizen, you may need evidence, information and expertise on many matters, ranging from marital issues to property disputes, inheritance cases, or legal issues.
Groupe Hyperion, bringing together detectives licensed by the CNAPS, aims to be the preferred point of contact for all individual needs.
We place great emphasis on the discretion of our actions, the confidentiality of the investigations we handle, and above all on smooth, attentive communication between you and us.
Our services for individuals
Marital and family matters
They are governed by law, so it is necessary to review each case with precision. The Groupe Hyperion handles adultery investigations, child custody matters, and the payment or revision of child support on a daily basis with its private detectives for individuals.
Background check
Before hiring an employee, entering into a partnership or starting a personal relationship, it is essential to verify an individual’s reliability. Our background checks help establish their past, criminal record, reputation and lifestyle. Protect yourself from unpleasant surprises with a discreet, in-depth analysis.
Search for missing persons
Whether it is a loved one you have lost touch with, an untraceable debtor, or a person missing in worrying circumstances, we implement advanced investigative techniques to find them. Thanks to our sources and expertise, we conduct effective searches in compliance with current legislation.
Property disputes
They can be a nightmare for an individual renting out one or more properties, especially when your tenants sublet. We carry out solvency investigations, standard investigations, and neighbourhood inquiries.
Inheritance and estates
They are always an ordeal for families. Triggered by a death, they can tear families apart. We intervene to investigate property and hidden assets, but also to identify heirs in order to close the estate.
