Private detective in Yvelines (78): Versailles, Saint-Germain

Versailles and its institutions, Saint-Germain and its families, the industrial Seine valley: the 78 requires knowing how to investigate in town as in residential suburbs.

Our detectives cover the whole Yvelines department: from Versailles (the préfecture) to Mantes-la-Jolie, Saint-Germain-en-Laye and Rambouillet, for family, wealth-related and industrial investigations. Reports are drafted for the Versailles courts, which have jurisdiction over the department.

Two investigation terrains in one department

The Yvelines combine high-stakes family and wealth cases: Versailles, Saint-Germain-en-Laye and Le Vésinet count among France’s wealthiest towns, and industrial matters in the Seine valley (Poissy, Flins, Les Mureaux): sick-leave fraud, shrinkage, subcontractor disputes. Surveillance in quiet residential streets, where any unknown car gets noticed, demands specific techniques: distant positions, adapted optics, investigator rotations.

Frequently asked questions

Yvelines: your questions

How do you watch a house without being noticed?
Never by parking in front of it: distant positions with optics, observation on the move, vehicle and investigator rotations. In residential areas, preparation counts double.
Do you operate as far as Mantes or Rambouillet?
Yes, the whole department is covered. For remote areas we group sessions to optimise travel costs, itemised in the quote.
