Legal framework
Private investigation bureaus in the Netherlands fall under the Private Security Organisations and Investigation Bureaus Act (Wpbr) and require a licence from the Dutch Ministry of Justice & Security (via Justis). Bureaus must also comply with the GDPR and offer a complaints procedure.
Evidentiary weight in court
Lawfully obtained evidence from a licensed bureau can be weighed by the court, usually alongside other evidence. Unlawfully obtained evidence (for example via hacking) risks being disregarded.

Frequently asked questions
Can evidence from a private investigator be used in court?
A report obtained lawfully can serve as supporting evidence. The court ultimately assesses its weight, often in combination with other evidence.
Can a private investigator follow me on the street?
Surveillance in public places is generally allowed, provided it is proportionate and not systematic without a justified purpose.
Can a private investigator wiretap or hack phones?
No. Wiretapping, hacking and placing hidden devices without a legal basis is a criminal offence, including for private investigators.
How do I check whether a bureau holds a valid licence?
