Signed documents constitute the foundation of dependencies, relationships and mutual obligations between the parties. Their credibility allows you to be sure that the data and agreements contained in official documents are binding or have been falsified with false signatures. Handwriting tests can also link the perpetrator to a given case or crime.


Verifying the authenticity of key documents should be part of the planned activities in building business relationships. It is a solid protection against fraud, loss of trust, financial losses or unsuccessful investments. The risk can be avoided by professional verification of the authenticity of, for example, signatures on distance contracts.

Our detective agency will verify the authenticity of any documents using innovative technology and specialized devices:

  • We perform graphological analysis of handwriting (in the case of electronic documents, the analyzes are performed by our IT forensics technicians).

  • We verify the compliance of the document with the indicated version and whether no changes have been made without the authorization of designated persons.

  • We check the authenticity of signatures.
In cooperation with a certified laboratory, we’re able to verify and confirm the authenticity of any type of document.

If you’re looking for comprehensive assistance in this area, we invite you to contact us as soon as possible. We will be happy to answer all your questions and explain our methods of operation.

We will guarantee you full discretion and, as the most experienced detectives in Poland, we will undertake even the most difficult tasks to help you.
