A divorce or separation is already emotionally difficult enough. But when the issue of child custody turns into a battleground, the situation can quickly become unbearable.
Accusations, doubts, legitimate concerns about your child’s well-being… Sometimes, words aren’t enough. You need facts—concrete evidence—that will allow the judge to make the right decision. That’s exactly where a private investigator in Paris can make all the difference.
Together with the Aquila Group, we regularly assist Parisian parents during these difficult times.
Our mission? To provide you with the objective information you need to protect your child’s best interests, in full compliance with the law and with the utmost discretion.
How a Private Investigator Can Help You in a Child Custody Dispute in Paris

What can a private investigator actually do in a child custody case?
Contrary to what we see in movies, a private investigator’s job is not to play the role of a vigilante. Our job is to document reality, step by step, without judgment or bias.
In practical terms, this means observing and collecting verifiable information on:
- Adherence (or lack thereof) to the custody schedule: Does your ex-spouse bring the children back at the agreed-upon time? Does he or she pick them up on the scheduled days?
- The child’s living conditions: housing hygiene, presence of potential hazards, and whether the environment is appropriate for the child’s age
- Social Circle: new partner, friends, people who are regularly present in the home
- Risky behaviors: excessive alcohol consumption, negligence, verbal or physical abuse
- Compliance with the educational framework: schooling, activities, and medical care
All of this is done in strict compliance with the law. We do not force our way into any premises, we do not install illegal listening devices, and we do not violate anyone’s privacy. We observe what can be legally observed, and we document it in an impeccable manner.
Evidence that the family court judge can actually take into account
You may be wondering, “Does a private investigator’s report really carry any weight in court?”
The answer is yes, provided that it is completely legal.
The Family Court Judge (JAF) bases his or her decisions on concrete evidence. A well-structured investigative report can be decisive in:
- Proving a violation of visitation or overnight stay rights: dates, times, witness statements, and time-stamped photographs
- Demonstrate a situation of concern for the child: unsuitable living conditions, dangerous behavior
- Supporting a request for sole custody when the situation truly calls for it
- Support a request to modify custody if circumstances have changed
- Challenging False Accusations Made Against You
The evidence we collect is admissible in court precisely because we strictly adhere to the legal framework. Every element of our report can be presented to the Family Court judge without the risk of being rejected on procedural grounds.

Mistakes to Avoid Before Hiring a Private Investigator in Paris
A 100% legal approach (and that is precisely what makes it so effective)
Hiring a private investigator in Paris for a child custody case is perfectly legal. But be careful: not all investigators are created equal, and certain practices can end up costing you dearly.
Always check for CNAPS certification
In France, it is illegal to work as a private investigator without a license from the CNAPS (National Council for Private Security Activities). Worse still: if your investigator is not licensed, their report will have no legal weight in court.
At the Aquila Group, all of our investigators are CNAPS-certified and adhere to a strict code of ethics. We are fully aware of the legal limits of our operations, and we never cross them.
Transparency and a Clear Contract
Each assignment is covered by a detailed written contract that specifies:
- The Objectives of the Survey
- The methods that will be used (and those that will not be used)
- Estimated duration of the procedure
- The estimated cost
No surprises, no gray areas. You know exactly what we’re going to do—and how we’re going to do it.
