Hiring a private investigator in Amsterdam to check on a cheating partner, when you live abroad

“I’m in another country and I can’t see anything myself”

It is one of the most common sentences we hear during an intake call. The caller is in New York, in London, in Dubai. Their partner lives, works or studies in Amsterdam. Something has changed, the tone of the messages, the rhythm of the calls, the explanations that no longer quite add up, and the distance turns ordinary doubt into something unbearable. You cannot drive past an address. You cannot see who shows up. You are thousands of kilometres away, holding a suspicion you cannot test.

This is exactly the situation a licensed Dutch private investigation agency is built for. Below is an honest, practical guide to how it works, what is possible, what is lawful, and how to do it from anywhere in the world.

Why distance makes infidelity so much harder

When you live with someone, doubt at least has an outlet: you can talk, observe, notice. When your partner is in Amsterdam and you are abroad, every channel of reassurance is also a channel for concealment. A “late meeting” cannot be checked. A “work trip” cannot be seen. The relationship runs on trust precisely because trust is all you have left, and that is corrosive when the trust is already cracking.

Hiring an investigator does not mean you have given up on the relationship. For most of our international clients it is the opposite: they want certainty so they can either rebuild on solid ground or stop torturing themselves with a suspicion that may not even be true. Both outcomes are a relief compared to limbo.

Can you really hire an investigator in another country?

Yes, and you can arrange almost all of it without leaving home. At SAJ Recherche a large share of partner investigations are commissioned by clients abroad. In practice it looks like this:

• The intake happens by phone or video call, scheduled in your time zone.
• The agreement and the quotation are handled by email.
• Payment is made by international bank transfer.
• The investigation is carried out on the ground in Amsterdam by local investigators.
• The report is delivered to you in English, wherever you are.

You never need to fly to the Netherlands. The only thing that has to be local is the fieldwork itself, and that is our job, not yours.

What a licensed Dutch agency can, and cannot, do

This is the part that matters most, and the part dubious “investigators” gloss over. SAJ Recherche holds a private investigation permit from the Dutch Ministry of Justice (POB 8779). That licence comes with strict rules, and those rules are what make the evidence worth having.

What we can do, lawfully:

• Discreet surveillance and observation of your partner’s movements in public space
• Documenting who they meet, where, and how often, with times and locations
• Photographic and video evidence where the situation allows
• Open-source and social-media research within legal limits (OSINT)
• Verifying identities, addresses, and whether a stated story holds up

What we will never do, no matter who asks:

• Hack a phone, email or social-media account
• Place illegal GPS trackers
• Break into homes, cars or devices
• Anything that would make the evidence inadmissible or expose you to liability

If an “investigator” offers to read your partner’s WhatsApp or clone their phone, walk away. Illegally obtained evidence is worthless in court and can turn you from the wronged party into the accused.

The Schiphol and “business trip” scenario

A specific pattern comes up again and again with international couples: the trips to Amsterdam that grow more frequent, longer and harder to explain. When the journey itself is the cover story, the journey is exactly what we examine. We can verify movements around Schiphol Airport and the city, hotel stays, and how the evenings are actually spent, and tell you whether the “conference” matches reality.

How the process works when you’re abroad

1. Free, confidential consultation. You tell us the situation; we tell you honestly what is realistically possible. No obligation.
2. Investigation plan and fixed quote. We agree the scope, surveillance, digital research, travel verification, or a combination, and you get a transparent price before anything starts.
3. Discreet fieldwork in Amsterdam. Our investigators do the work locally while keeping you updated.
4. A clear report in English. You receive a structured written report with our findings and any evidence, prepared to the standard lawyers and courts expect.

Is the evidence usable in court?

For Dutch proceedings, divorce, alimony, division of assets, custody, the answer is straightforward: our reports are produced to the standard the courts require and are used in exactly these cases. For proceedings outside the Netherlands, admissibility depends on your local law, so the right step is to share the report with your own lawyer. Because the evidence is gathered lawfully and documented professionally, it travels far better than anything obtained through shortcuts.

What it costs

Our rate starts from €125 per hour, excluding VAT. After the free intake you receive a fixed quotation tailored to your situation, so you know the full cost before the investigation begins. There are no misleading teaser prices, just a clear figure agreed in advance.

You don’t have to keep guessing

Doubt at a distance is its own kind of exhaustion. Whether the truth confirms your fear or sets it to rest, knowing is what lets you act. SAJ Recherche is a licensed Amsterdam agency that works with clients across the world, entirely in English and entirely in confidence.
