Partner Investigation Amsterdam
When your partner is in Amsterdam and the doubt won't stop
Few things are harder than suspecting the person you love, and being unable to see anything yourself because you live abroad, because the relationship spans countries, or because every trip to Amsterdam has become harder to explain. The uncertainty is paralysing. SAJ Recherche is a licensed Dutch private investigation agency based in Amsterdam. We work with international and expat clients who need clarity about a partner here: discreet surveillance, factual evidence, and a clear report in English. Either we confirm what you fear, or we let you put the doubt to rest. Either way, you can finally move forward.
What we can establish
Surveillance & discreet observation
Our investigators follow and document your partner's real movements in Amsterdam and the wider Randstad, where they go, how long they stay, and who accompanies them. Every observation is logged with times, locations and, where possible, photographic evidence.
Who they really meet
We establish whether the "colleague", "friend" or "business contact" is what they claim to be. We confirm identities, the nature of the contact and the frequency of meetings, facts, not assumptions.
A second life or hidden relationship
When a partner maintains a double life, there is almost always a pattern: a recurring address, a second phone, unexplained spending, repeated "trips". We map that pattern and document it objectively.
Schiphol & travel verification
Is the "business trip" to Amsterdam real? We can verify arrivals and departures, hotel stays and movements around Schiphol and the city, useful when a partner travels internationally and the trip itself is the cover story.
Digital & open-source (OSINT) investigation
Within strict legal limits, we examine public sources, social media and digital traces that confirm or contradict your partner's account. We never hack phones or use illegal tracking, only evidence that holds up.
Photographic & video evidence
Where the situation allows, we secure dated photographic and video material. Combined with a written report, this is the kind of concrete proof lawyers and courts take seriously.
Stop guessing. Get the facts.
A free, confidential consultation, wherever you are in the world.
Who we help
Built for clients who can't be here themselves
Most of our partner-investigation clients are not standing in Amsterdam. They are abroad, travelling, or living here as expats, and they all need the same thing: someone local, discreet and trustworthy.
You live abroad
Your partner is in Amsterdam, you are not
You are in the US, the UK, the Gulf or anywhere else, and your partner lives, works or studies in Amsterdam. Distance makes doubt unbearable because you cannot see anything yourself. We become your eyes on the ground, a licensed Dutch agency acting locally, reporting to you in English wherever you are.
The "business trip"
Your partner travels through Schiphol
The trips to Amsterdam have become more frequent, longer, harder to explain. When the journey itself is the cover story, we can verify whether the business trip is real, movements around Schiphol, the hotel, the evenings, and tell you what is actually happening.
Expat in Amsterdam
You live here, but the system is foreign
You moved to Amsterdam together, or you are building a life here, and something has changed. Navigating a Dutch investigation in a second language is daunting. We work entirely in English, understand the expat reality, and handle everything discreetly and lawfully.
