Electronic Evidence,
Prepared to Litigation Standard
Engineering rigour applied to digital evidence extraction, analysis, and court-ready preparation — for lawyers who need more than a report.
The practice
Most electronic evidence work stops at retrieval. At SERSO Investigations, it starts there. With a background in software engineering and data systems, Sergio de Sousa applies structured analytical methodology to digital evidence — extracting, processing, and presenting it in a form that is precise, traceable, and ready for use in court or arbitration proceedings.
If your matter involves electronic records, device data, or digital communications, you need a specialist who understands both the technology and the evidentiary demands of litigation.
