Chain of Custody for Digital Evidence
Boston-based, serving clients nationwide by appointment.
If you're handling evidence for a legal or insurance matter, chain of custody is the written record that shows what was received, when, from whom, and how it was handled—so handling and transfer history can be reconstructed later.
Data365 Evidence provides chain-of-custody documentation and preservation-first evidence handling for legal and insurance-related matters. Boston-based, serving clients nationwide by appointment. Forensic data acquisition is performed where appropriate under confirmed engagement terms. Intake begins with a written record identifying source details, access authority, and transfer decisions.

- Time reference: Dates and times recorded using a consistent time standard.
