Private Investigator in Paris | Aquila Group

The Aquila Group operates its investigative services in Paris from its historic headquarters located at 47 rue de Monceau, in the 8th arrondissement. This central location allows us to respond quickly throughout the capital and its immediate suburbs.
The city of Paris has unique characteristics that require specialized expertise: extreme urban density, a complex public transportation network, diverse neighborhoods, a high concentration of international companies, and a demanding, cosmopolitan clientele. Our Parisian detectives are thoroughly familiar with these factors and adapt their investigative methods accordingly.
We operate in the central arrondissements (1st, 2nd, 8th, 9th) as well as in business districts (La Défense, accessible from the 17th), upscale residential areas (16th, 7th), and working-class neighborhoods. Our in-depth knowledge of the Parisian landscape allows us to conduct discreet surveillance in all environments.
The Paris Court, located on the Île de la Cité, now centralizes all legal disputes for the capital and the inner suburbs. Our investigative reports are drafted in accordance with the standards required by this court and are fully admissible before its various divisions (civil, commercial, and labor).

Parisians face complex personal and family situations that often require the services of a private investigator to uncover the truth with solid evidence.

Do you suspect your spouse of infidelity in the capital? The Parisian setting offers countless opportunities for encounters and makes surveillance more difficult: frequent trips on the metro, numerous hotels, company apartments, and after-work social events. Our detectives conduct discreet surveillance using all forms of Parisian transportation (subway, bus, bicycle, car, and on foot) and gather evidence of adultery that can be used in family court proceedings before the Family Court Judge at the Paris Tribunal.

This evidence can significantly strengthen your divorce case: spousal support, division of property, and child custody. Our experience with family law litigation in Paris allows us to anticipate the expectations of the judges and produce reports that your attorney can use immediately.

In disputes regarding children’s residence following a separation, the Family Court Judge at the Paris Court relies on objective factual evidence. We document your children’s actual living conditions: adherence to custody schedules, school attendance, family environment, and the custodial parent’s actual presence.

In Paris, where many parents have demanding jobs and rely on alternative childcare arrangements (nannies, daycare centers, grandparents), it is crucial to prove each parent’s actual availability and concrete involvement. Our investigations provide this objective evidence, which is essential to defending your interests and those of your children.

We also verify that child support payments are actually being made and can locate a parent who has failed to meet their obligations.

Finding someone in a city of 2.2 million people like Paris is a challenge that requires professional resources. Whether you’re looking for a missing loved one, a debtor, an heir in connection with an estate, or a former partner, our detectives use their networks, professional databases, and investigative techniques to locate the people you’re searching for.

Mobility in Paris (frequent moves, changes in arrondissements) makes these searches complex, but our local expertise and proven methods enable us to achieve concrete results.

Paris is home to a vast real estate portfolio and often complex estates. We step in to verify the accuracy of asset declarations, search for hidden assets, locate heirs, document the actual occupancy of a Parisian property, or investigate cases of inheritance fraud targeting vulnerable individuals.

The capital is home to the largest number of businesses in France. This dense economic fabric presents specific investigative challenges, to which our detectives provide tailored solutions.

Is an employee on sick leave in Paris engaged in an activity incompatible with his or her reported medical condition? Is he or she playing sports, working for a competitor, or working as a consultant? Our discreet surveillance operations allow us to gather video and photographic evidence that can be used in proceedings before the Paris Labor Court.

In a city where people are constantly on the move and engaged in a wide range of activities, only professional monitoring can determine whether the claimed disability is genuine. Our investigative reports provide legal safeguards for your HR decisions and can serve as grounds for disciplinary action or termination for serious misconduct.

Parisian companies, regardless of their industry, are not immune to internal misconduct: embezzlement, theft of merchandise, fraudulent use of company resources, falsification of expense reports, and breach of trust. We identify the perpetrators of these frauds, establish the facts of the case, and gather evidence to support legal action or disciplinary proceedings.

Our absolute discretion ensures that the investigation will not disrupt the operations of your Paris-based teams.

Paris is home to numerous corporate headquarters and is a hotbed of intense competition across all sectors. Large-scale poaching of employees, unlawful use of customer databases, commercial disparagement, breach of non-compete clauses, and disclosure of confidential information: we investigate these unfair practices and compile the necessary evidence to file a case with the Paris Commercial Court.

Protecting your know-how, strategic data, and competitive advantages requires constant vigilance. Our security audits identify vulnerabilities in your Paris-based company regarding the risks of industrial espionage.

Before hiring a senior executive or a key employee for your Paris-based company, ensure your decision is sound by verifying the authenticity of their degrees, professional experience, references, and the absence of any prior legal disputes. A bad hire in Paris—where salaries are high and severance pay is substantial—can be very costly for your company.

Lawyers, bailiffs, and legal professionals in Paris regularly turn to us to strengthen their litigation cases.

We work with legal professionals practicing in Paris to:

• Gathering Additional Evidence Prior to a Hearing at the Paris Tribunal or Before the Paris Court of Appeals
• Locating debtors to facilitate the enforcement of court orders and enable service of process by a bailiff
• Credit checks to assess a party’s actual financial capacity before initiating legal proceedings
• Counter-investigations to verify or challenge evidence presented by the opposing party
• Factual findings admissible in civil, commercial, or labor proceedings
