Maintenance fraud investigation: proving undisclosed income or cohabitation
Do you suspect your ex-partner is concealing income or cohabiting without declaring it, affecting maintenance payments? Santos Recherchebureau investigates the actual living and income situation and documents it in a report you can use with your lawyer or in court.
The maintenance no longer matches what you see: a new car, a partner who consistently stays overnight, undeclared work. Proving it yourself is difficult. We do it carefully and objectively.
Common signs
- Indications of cohabitation that hasn't been reported
- Visible prosperity inconsistent with declared income
- Unclear freelance or undeclared work
- Refusal to share financial information transparently
How we work
We establish the actual living pattern through:
- A lifestyle investigation to establish the actual living pattern
- Static and dynamic surveillance at relevant times, such as overnight stays, using our own camera vehicles where needed
- Research using public and digital sources on work and income
- A well-substantiated report suitable for submission to your lawyer

Frequently asked questions
Can this investigation really affect maintenance payments?
An objectively established living pattern can form relevant evidence in proceedings to modify maintenance. The final legal assessment rests with the court or your lawyer.
Can cohabitation actually be proven?
Cohabitation is usually demonstrated through a combination of surveillance, pattern recognition and supporting sources, never a single moment.
Do you work with lawyers?
Yes, we regularly provide well-substantiated reports to lawyers and offer clarification where needed.
How long does such an investigation typically take?
Often several weeks, since a reliable pattern takes time to become visible.
