Private Investigator for Child Custody Cases in France

When the child’s best interests are at stake

When a parent is concerned about the conditions under which their child is being cared for by the other parent, the matter is too serious to rely solely on impressions. An unsuitable environment, insufficient supervision, the presence of a problematic third party, or failure to adhere to the schedule: these fears, if well-founded, must be supported by concrete evidence to carry weight before a family court judge.

A simple assertion carries little weight in legal proceedings; a documented finding, legally established by an investigator, can, on the other hand, influence a custody decision. That is the whole point of a professional approach: to move from feelings to evidence, calmly, without dramatizing the situation and without exposing the child.

Conversely, acting alone—questioning the child, fueling suspicions, and gathering worthless evidence—risks antagonizing the other parent and undermining your case. Hiring a licensed private investigator allows you to gather objective, actionable evidence while ensuring the child’s well-being.

What Our Survey Covers

Our work focuses on the actual conditions of care and safety, without ever involving or disturbing the child:

  • Observation of living conditions and the living environment;
  • Verification of compliance with the established schedules and childcare arrangements;
  • Identification of the people present with the child;
  • Identification of behaviors or situations that may pose a risk;
  • A compilation of dated and documented evidence that can be used in court.

Each observation is time-stamped and recorded in a clear report, designed to support a request to modify custody arrangements. The child’s safety and well-being remain our top priority throughout the assignment.

How is the investigation proceeding?

After an initial confidential consultation—which is free and non-binding—we work with you to define the objective and scope of the investigation, and then provide a clear quote. Our investigators then observe relevant details in the field, anywhere in France, with the utmost discretion and without ever coming into contact with the child. You will receive a detailed, illustrated report, prepared to be submitted to a family court judge or used by your attorney. The scope of the investigation can be adjusted during the course of the assignment if the situation changes.

Why Choose the Aquila Group

The Aquila Group is a private detective agency accredited by the CNAPS. Your cases are handled by our own investigators, and we respond quickly throughout France—with particularly high demand in the Paris region—thanks to our network of twenty offices across five regions.

We handle these cases with particular care: a child is involved, and the goal is to help the child, not to expose the child. These situations often involve other issues, such as the adjustment of child support. To discuss your situation with us, please contact our team : the initial consultation is free and requires no commitment.

A report that carries weight with the family court judge

To modify custody arrangements, the judge needs tangible and verifiable evidence, not mere accusations. Our report meets this requirement: it documents dated observations, objectively describes the conditions observed, and clearly distinguishes established facts from mere impressions. Presented in this manner, it provides strong support for your request or for your attorney’s work.

We ensure that each observation is placed in its proper context to avoid any biased interpretation. A credible report is not an indictment: it is a balanced document that reports what has been observed and leaves it to the judge to assess. Paradoxically, this neutrality strengthens the impact of your arguments.

Child safety: our guiding principle

At no time is the child approached, questioned, or placed in a specific situation. Our investigators observe only the external conditions and the environment, with absolute discretion. The goal is never to exploit the child, but to ensure that his or her living situation is in the child’s best interest, which takes precedence over everything else.

We know how stressful these situations can be for a concerned parent. That’s why we proceed with caution, keeping you informed every step of the way and tailoring our efforts to the specific circumstances of the custody arrangement being reviewed. You remain in control: nothing is done without your consent, and the scope of our work can be adjusted if the situation changes.

This commitment to caution and respect, combined with the thoroughness of our findings, makes all the difference when it comes to protecting a child and defending your role as a parent.

How long does this type of investigation take?

The duration depends on the custody arrangements to be verified and the frequency of the situations to be observed. Some verifications focus on a single weekend or a specific period of visitation; others require observing multiple instances to establish a pattern of recurrence. We work with you from the outset to define a realistic framework and provide a clear estimate.

We always prioritize a proportionate investigation: neither overly extensive nor insufficient in light of what you are seeking to demonstrate. This approach protects your budget while ensuring the report’s robustness, and remains flexible should the situation change during the course of the assignment.

Finally, keep in mind that an investigative report does not, on its own, determine the outcome: it provides guidance to the judge, who retains ultimate authority in making the decision. Our role is to provide the judge with a reliable factual basis—in addition to the other evidence in your case—so that the decision best serves the child’s best interests. We make it a point of honor to ensure that our findings are impeccable in both form and substance, as it is this quality that gives them weight. And because these proceedings take place during a difficult time in your life, we remain available and attentive to you and your attorney from the first meeting until the decision is reached, without ever putting any pressure on you.
