Infidelity investigation: clarity when you suspect your partner is cheating
An infidelity investigation by Santos Recherchebureau discreetly maps your partner's behaviour and encounters, using surveillance and, where relevant, digital research. You receive an objective, factual report with photo or video evidence: certainty, whether that means moving on or laying your suspicion to rest.
You notice it in small things: a phone that never lies face-up on the table anymore, an evening explained as ‘work’ that doesn't quite add up. Often certainty is the only thing missing, and that's what we provide, with facts instead of assumptions.
Common signs
- Unexplained absences or inconsistent stories about their schedule
- Sudden secrecy around a phone, laptop or social media
- Unexplained expenses or changes in appearance
- A persistent gut feeling, even after talking about it

Frequently asked questions
Is evidence from a private investigator valid in court?
A report prepared carefully and within the legal framework can serve as supporting evidence, for example in divorce proceedings. Its evidentiary weight depends on how the investigation was conducted; we always operate within the Wpbr and GDPR.
How long does an infidelity investigation take?
This varies: from a short surveillance session of a few hours to an investigation spanning several weeks. We give a realistic estimate during the intake call.
Will my partner find out they're being investigated?
Discretion is our top priority. Our investigators are trained to work unobtrusively so the investigation doesn't disrupt the situation.
What if nothing is found?
That is valuable information too. An objective report finding no evidence of infidelity can still bring peace of mind.
