Private Investigators in Lisbon: Confidential Investigations and Legal Evidence
Agência De Investigação Particular Lisboa
Dear Visitor ...
I assume this is the first time you've used the services of a A private detective or an investigation agency who has no idea how this activity or type of service works.
I am informing and warning you to be careful and attentive, this activity is not legalized in Portugal . And when there is no law regulating an activity, there are many curious individuals and swindlers, always ready to try their luck through newspaper ads, websites, or any other type of advertisement, trying to sell illusions, which are not always cheap.
Many people, for the first time, find themselves forced by the necessity of a problem to resort to a private investigator , usually desperate and emotionally fragile. They can easily fall for a scam and end up empty-handed. Only later do they realize they have fallen for a cleverly orchestrated hoax.
Report this to the Judicial Police immediately. Even if you don't want to expose yourself or make yourself known, report it anonymously, providing as much detail as possible. Serious professionals will appreciate it.

As investigative specialists, discretion is our fundamental principle. We neither intend nor should we appear on television; we prioritize anonymity to preserve the effectiveness of our field operations—which is where we are truly useful and important to our clients.
However, our technical expertise makes us a benchmark in the sector. This often leads us to be a source of information for national television channels, as happened in this TVI report, which cites data and experience from the company Detetives Privados Portugal.
Trust is built on results and confidentiality , not on exposure.
