The civilian investigator does not replace the police but can be complementary in investigations, whether private or judicial. Our agency is made up of trained private investigators who resolve inquiries in strict accordance with the law. Its director, a former executive of the judicial police, directs all the investigations carried out by the agency and thus guarantees a quality service and impeccable confidentiality to its clients.

Throughout the investigations, the customer is informed as often as he wishes. At the end of the investigation, a detailed report is drawn up and given to the client confidentially. This document comprehensively includes all the elements obtained and / or observed during the investigation. If necessary, during complex investigations or over a longer period of time, one or more interim reports can also be drawn up on a regular basis. The reports of our additional investigations can be presented to justice by the client. In this case, it is then up to the competent authority to take appropriate action or to rule directly on the content thereof.

But we are also at your disposal for any other personal inquiry you wish. Your requests are all considered and if necessary discussed to determine the best approach and solution to carry them out.

Complementary private, civil or judicial investigations can be not only important but crucial in the search for the truth. We carry out computer research, research in the field and this without territorial limit. We also carry out surveillance and monitoring without time limit.

For each case submitted to the agency regarding further investigations, we listen carefully to the wishes and intentions of the client. We discuss the elements already in its possession and define the objectives to be achieved. Together, we assess the possibilities of investigation and the means that are necessary to put in place to achieve the defined objectives as well as possible and as quickly as possible. If necessary, we advise the client on the basis of our extensive experience and we offer him the various possible and conceivable alternatives.

At the start of each investigation, the strategy and content of the investigations to be carried out are discussed with the client and common sense will prevail in all sensitive cases. At any time, the client can choose to stop or suspend the investigations according to his wish.
