Licensed corporate & legal investigation, nationwide

When a Dutch matter needs facts your legal team can rely on, a fraud in the supply chain, a director whose background does not add up, a claim that looks staged, a boardroom you suspect is not secure, you need a licensed local investigator, not an intermediary. SAJ Recherche is a private investigation agency licensed by the Dutch Ministry of Justice (POB 8779), based in Amsterdam and working across the Netherlands for foreign corporates, Dutch companies, law firms and insurers. We run under NDA, coordinate with your counsel, and deliver evidence that holds up under Dutch scrutiny.

What a licensed private investigator in the Netherlands can do for your organisation

Corporate fraud investigation

Invoice fraud, procurement kickbacks, embezzlement, false expense claims, phantom vendors. We map the facts objectively across Dutch entities and report in a form your legal team, insurer or auditor can use.

Due diligence on Dutch counterparties

Verify a Dutch company, director or shareholder before you invest, acquire, partner or extend credit. UBO, KvK, sanctions, litigation history, adverse media, and where legally possible, discreet field verification.

Pre-employment & integrity screening

Structured background checks on candidates for senior, financial or safety-critical roles anywhere in the Netherlands, within Dutch privacy law and the GDPR. Reports lawyers and HR directors can rely on.

Insurance & liability investigation

Suspected claim fraud, exaggerated injury, fictitious loss, staged incidents. Discreet observation and factual reporting for insurers, brokers and self-insured corporates operating in the Netherlands.

Litigation support & evidence gathering

For law firms preparing Dutch or cross-border proceedings: fact-finding, witness location, asset tracing, surveillance to establish behaviour, and reports drafted to hold up in Dutch court.

TSCM sweeps for boardrooms & directors

Technical surveillance countermeasures for boardrooms, executive offices, law-firm meeting rooms and directors' residences anywhere in the Netherlands. Full inspection, findings secured and reported.

Under NDA. Discreet from the first call.

A confidential scoping session, in English, wherever your legal team sits.

Built for organisations with a Dutch matter

Our corporate clients are foreign multinationals, Dutch companies, in-house counsel, law firms and insurers, all needing the same thing: a licensed local investigator who reports clearly in English.

Foreign corporate

You need a Dutch investigator, not a translator

You are a US, UK, DACH or Asian company with a matter in the Netherlands: a fraud, a due-diligence, a counterparty, an employee. We act on the ground here and deliver evidence in English that your global team can act on.

Dutch company or in-house counsel

You want a licensed, discreet partner

Corporate matters do not survive leaks. We are a licensed Dutch agency (POB 8779) that works confidentially, coordinates with your legal counsel, and produces reports that hold up under Dutch scrutiny.

Law firm & legal team

You need evidence that stands up in court

We partner with Dutch and international law firms on fact-finding, surveillance, witness tracing and asset investigation. Our reports are drafted to survive the standard of a Dutch civil or criminal proceeding.

How we work

1

Confidential intake & scoping

A first call under NDA. We listen, assess what is realistically possible under Dutch law, identify the risks and advise on the most efficient approach. No obligation.

2

Investigation plan & written agreement

A written proposal with scope, methods, deliverables, budget and timeline. Your legal counsel reviews and signs off before any field or digital work starts.

3

Nationwide investigation

Our investigators execute across the Netherlands, in Amsterdam, Rotterdam, The Hague, Utrecht, Eindhoven and beyond, strictly within Dutch privacy law and the GDPR. You receive scheduled progress updates.

4

Reporting for legal or corporate use

You receive a structured written report in English with findings, source references, photographic or video evidence, and, where relevant, an expert declaration usable in Dutch proceedings.

Licensed, discreet, and built for regulated matters

Corporate investigations survive or fail on defensibility. A leaked source, an unlawful method, a report that will not hold up in a Dutch civil chamber, any of these can turn a legitimate matter against the client. We work within the Wpbr, Dutch privacy law and the GDPR, coordinate with counsel from the start, and document methods and sources so the report withstands challenge.

We handle every step in English, run under NDA, and never ask a client to authorise anything unlawful.

  • Licensed by the Dutch Ministry of Justice, permit POB 8779
  • KvK 96790954, VAT NL867763437B01
  • Reports drafted for Dutch civil, employment and fraud proceedings
  • Coordination with in-house and external legal counsel
  • Nationwide reach: Amsterdam, Rotterdam, The Hague, Utrecht, Eindhoven, provinces

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.
