§ Common questions

Frequently asked questions

What is e Disclosure, and how is it different from simply exchanging documents?
e Disclosure is the defensible process for per form in g disclosure on electronically stored information: identifying and preserving sources, collecting them without damaging metadata, processing and culling the volume, review in g for relevance and privilege, and producing in agreed formats with an audit trail. Simply exchanging documents is only the last step of that chain, performed without the process that makes it complete, verifiable and safe to certify. The rules (PD 57AD; PD 31B) assume, and in places require, the process, not just the exchange.
Do we need an e Disclosure exercise in a small case?
You always need the duties discharged, preservation, honest search, accurate certification. The machinery scales: a two-custodian dispute may need only a hold notice, a documented mailbox export and a small review database. What never scales down is self-collection by the client and unpreserved phones.
Can we just print the Whats Apps / take screenshots?
Screenshots prove that pixels existed on a screen; they carry no metadata, omit context, and are trivially fabricated, courts and tribunals increasingly say so. Extract chat evidence forensic all y from the handset or backup so completeness and integrity can be demonstrated.
Is technology-assisted review accepted by the courts?
Yes. English courts approved predictive coding in Pyrrho (2016) and have treated it as unexceptional since; PD 57AD's DRD asks parties to state whether they will use analytics and TAR, and larger parties may be pressed to justify not using it. The defensibility question has moved from "may we?" to "how was it validated?"
Who pays for all this?
Each party generally bears its own disclosure costs, subject to costs budgeting and the ultimate costs order, but disproportionate demands can be met with applications to shift or cap costs, and disclosure conduct (good and bad) is regularly reflected in costs awards. The cheapest lever remains scope: custodians, dates and sources.
What happens to the data when the case ends?
It should be returned or verifiably destroyed under the provider contract and the client's retention policy, subject to any surviving obligation (appeal windows, related proceedings, regulatory holds). Indefinite hosting of a litigation database full of third-party personal data is a data-protection liability with a monthly invoice attached. cflab. u k · e-disc ove r y. u k ©2026 Computer Forensics Lab Ltd ·cflab.uk ·e-discovery.uk ·info@cflab.uk ·+44 (0)20 7164 6915 Page 31 of 34
