Document Analysis and Forensic Examinations - Scientific Certainty of Authenticity

Through cooperation with experienced court experts and forensic laboratories, we provide comprehensive support for private individuals, law firms, and businesses.

Authenticity matters – especially when legal rights, assets, or reputation are at stake.

A signature is often the most important element of a document. Our signature examinations make it possible to determine whether a signature was made by the authorized person or whether it has been forged, copied, or technically reproduced.

As part of signature analysis, we offer:

• comparative analysis of original and disputed signatures
• identification of individual handwriting characteristics
• detection of imitation or mechanical reproduction attempts
• assessment of writing instruments and document surfaces
• preparation of an expert opinion suitable for court proceedings

Signature examinations are frequently a key piece of evidence in inheritance, property, commercial, and criminal cases.

Graphology is a scientific method of examining handwriting, enabling the identification of the author of a text, the assessment of the authenticity of notes or letters, and the analysis of the emotional state at the time of their writing.

Use of graphological research:

• verification of authorship of anonymous writings,
• analysis of private and official documents,
• supporting court proceedings,
• examination of the compliance of signatures on contracts and declarations,
• establishing the credibility of manual records.

Graphology combines science and psychology, providing a reliable picture of the identity of the author of a document.

Document forgeries can take many forms – from crude copies to professional counterfeits using digital techniques.

Detectum conducts authenticity checks on documents, including contracts, invoices, powers of attorney, diplomas, wills, promissory notes, and certificates.

Verification includes, among others:

• analysis of the structure of paper and paint,
• checking watermarks and security features,
• comparison of prints, numbering and digital inserts,
• metadata analysis of PDF files and electronic documents,
• weryfikację integralności treści oraz historii zmian.

Any deviation from the original may have evidentiary significance – that is why our analyses are carried out with the utmost precision.

In the age of digital transformation, more and more documents exist exclusively in electronic form. Detectum offers both physical examinations (paper, ink, printing techniques) and digital analyses (PDF, JPG, DOC files, emails, electronic signatures).

Our activities include:

• analysis of paper and digital media,
• checking metadata and file editing history,
• restoring deleted data or document layers,
• verification of electronic signatures and certificates,
• preparing a report with research results for the court or client.

Modern computer forensics tools allow us to precisely identify the source and authenticity of a document.

We collaborate with court experts in the fields of forensics, graphology, and document analysis.

Based on the results of our research, we prepare expert reports and opinions for courts, law firms, and individual clients.

Our studies include:

• detailed description of research methods,
• evidentiary results and conclusions,
