Private Detective Netherlands
A licensed Dutch detective, wherever the matter sits
When you need certainty about something in the Netherlands, a partner in The Hague, a business contact in Rotterdam, a person in Eindhoven, an address in Utrecht, you need more than an amateur with a camera. SAJ Recherche is a private investigation agency licensed by the Dutch Ministry of Justice (POB 8779), headquartered in Amsterdam and operating nationwide. We carry out discreet, lawful fieldwork on the ground and report to you in clear English, whether you are an expat here or watching from abroad. Either we confirm what you suspect, or we let you put the doubt to rest, with evidence that stands up.
What a licensed private detective in the Netherlands can do for you
Partner & infidelity investigation
Discreet confirmation of what is really going on when you suspect a partner. A frequent request from clients abroad whose partner lives, works or travels in the Netherlands. Nationwide coverage from Amsterdam to Groningen.
Surveillance & discreet observation
Our investigators follow and document a subject's real movements anywhere in the Netherlands: where they go, how long they stay, who they meet, logged with times, locations and photographic evidence.
Background checks on individuals
Verify someone before you trust them: a new partner, a business contact, a nanny, a caregiver, a landlord or a Dutch counterparty. We work within Dutch privacy law and report facts that hold up.
Digital & open-source (OSINT) investigation
We examine public sources, social media and digital traces that confirm or contradict an account. We never hack devices or use unlawful tracking, only evidence that stands up in court.
Missing persons & address tracing
Locating a person who has cut contact, a debtor, a family member, an inheritance heir, or verifying an address in the Netherlands. Handled discreetly and within the law.
TSCM bug sweeps
Suspect a hidden camera or listening device in a Dutch hotel room, Airbnb, boardroom or private home? Our technical countermeasures team detects covert devices anywhere in the country.
Stop guessing. Get the facts.
A free, confidential consultation, wherever you are in the world.
Who we help
Built for clients who need a Dutch detective they can trust
Our clients are internationals abroad, expats living in the Netherlands, and families with cross-border matters, all needing the same thing: a licensed, discreet detective who reports clearly in English.
You live abroad
You need eyes on the ground in the Netherlands
You are in the US, the UK, the Gulf, Asia or elsewhere and need something verified in the Netherlands, a partner, a person, a business contact, an address. We act locally and report to you in English, wherever you are.
Expat in the Netherlands
You live here, but the system is foreign
Navigating a Dutch investigation in a second language is daunting. We work entirely in English, understand the expat reality across Amsterdam, The Hague, Rotterdam and beyond, and handle everything discreetly.
Cross-border families
The matter crosses countries
Alimony, custody, hidden assets, inheritance, missing family members. When facts sit on both sides of a border, you need an investigator who reports in a form your foreign lawyer can use.

Words cannot express how professional and excellent John's work was. We hired him to prove a case of infidelity, and his expertise exceeded all our expectations. Everything was done with precision and speed. From the moment we contacted him he gave us the confidence we needed during a very difficult time for our family. He is a true professional and a wonderful person. Thank you John for your dedication to our case. Our family is eternally grateful.
