Aimed at UK lawyers navigating modern e-discovery, this guidance addresses the challenge of identifying and recovering automatically generated drafting records across cloud platforms before retention limits, migrations, or improper file moves destroy them. Platforms like SharePoint, OneDrive, Google Drive, and document management systems generate attributed, timestamped version ladders, supported by wider source architecture including internal metadata, audit logs, sent email copies, local caches, and endpoint backups. Failing to collect these assets forensically risks flattening the chronological sequence into a static file, directly threatening document authenticity, privilege considerations, and disclosure scope. By exploring worked examples of missing histories, technical limitations, and common operational mistakes, the text provides practitioners with specific checklists, red flags, and interrogatory wording to put to opponents, clients, and e-discovery providers. Furthermore, it outlines ISO 17025-aligned procedures required for preserving a full chain of custody and preparing CPR Part 35 expert reports, establishing clear technical and legal parameters for when solicitors should instruct a specialist digital forensics laboratory to prove critical authorship and chronology.

§ 13 · COMMON QUESTIONS Frequently asked questions Are prior versions really "documents" we have to disclose? The version history on our key document is missing. Does that look bad? Can the platform tell us who made a specific change? We only have the document as an email attachment. Is that enough? How far back do version histories go? Do drafts carry privilege the final does not?
