Digital Evidence Service Provider Subpoena Guides & Templates
A Practical Guide for Defense Attorneys and Investigators
Technology companies, cellular carriers, internet providers, cloud services, and social media platforms may hold records important to identity, location, communications, account access, online activity, and case timelines. Some records are retained only briefly. Others may require specific identifiers, legal authority, or provider-specific language before they can be preserved or produced.
This guide helps defense attorneys and investigators identify the correct provider, determine what records may exist, preserve time-sensitive information, prepare focused requests, and review provider productions.
Key point: A subpoena guide is a starting resource—not a guarantee of access. Provider practices, retention periods, legal requirements, portals, and contact information change. Confirm current requirements before sending any request.
