§ 01
UK forensic collection
On-site or remote collection across the UK, hash-verified, with a signed collection statement and full chain of custody to NPCC guidelines.
§ Cross-border · For US counsel · Reviewed September 2026
Evidence in the UK, produced to US standards.
For US litigation teams with custodians, servers or witnesses in the United Kingdom. We collect forensically in the UK, minimise and review in the UK, transfer under a lawful mechanism, and produce to your ESI protocol in a format your vendor can load. Terminology on this page is given in both vocabularies: UK eDisclosure, US eDiscovery.

§ 02 · The problem
Why UK evidence goes wrong for US teams.
Nearly every problem we are asked to repair began with a collection that ignored UK constraints.
Risk
Remote self-collection by the custodian
A UK employee zipping their own mailbox destroys metadata, misses deleted and archived content, and is difficult to defend if authenticity is challenged.
Risk
Transfer before minimisation
Shipping a full forensic image to a US vendor makes the UK GDPR transfer analysis far harder than it needed to be. Filter first, in the UK.
Risk
Personal devices treated as company property
UK employment and data protection law constrains what can be taken from a personal phone. Consent has to be informed and the scope has to be narrow and recorded.
Risk
Protocols written for US systems
An ESI protocol demanding metadata fields that a UK on-premises Exchange or a Teams export never carried creates a production dispute months later.
§ 03 · Scope
What we do for US teams.
A single UK counterparty from preservation notice to produced volume.
§ 02
Minimisation in the UK
De-duplication, date and custodian filtering, search terms, threading and near-duplicate grouping applied before any transfer, with the reduction documented.
§ 03
Transfer mechanics
Transfers under the IDTA or the UK Addendum with a transfer risk assessment, or under the Data Privacy Framework where the recipient is certified, with encryption in transit and at rest.
§ 04
FRCP-ready production
TIFF or PDF with searchable text, natives for structured data, Bates or control numbering, agreed metadata fields, privilege log support and a load file your vendor can ingest.
§ 05
Expert evidence
Witness statements and expert testimony on methodology, authenticity and chain of custody, given remotely for US proceedings or in person in the UK.
§ 06
Letters of request
Practical support for Hague Evidence Convention requests executed in England and Wales, including realistic scoping before the request is drafted.
§ 04 · Why e‑discovery.uk
Why a UK-based partner rather than a UK office of a US vendor.
Both work. These are the differences that show up on a matter.
The data stays in the UK until it should not
Processing and hosting in the UK by default, so the transfer question is answered once, deliberately, with a minimised set.
Forensics is the core discipline
The same practice that runs the review also does the imaging, so authenticity questions are answered by the person who did the work.
One senior contact
The practitioner who scopes the collection supervises it. There is no account layer between you and the examiner.
Where we do not compete
For petabyte-scale second requests with round-the-clock global review capacity, a large global vendor is the right answer, and we will say so.
§ 05 · Typical matters
The rules and instruments that govern this work.
Cited so your team can check the position rather than take ours on trust.
- ▸Federal Rules of Civil Procedure 26 and 34 on the scope, proportionality and form of production of ESI, and Rule 37(e) on failure to preserve.
- ▸Federal Rule of Evidence 502 and clawback agreements for inadvertent disclosure of privileged material.
- ▸UK GDPR and the Data Protection Act 2018, in particular Chapter V on restricted transfers, the ICO International Data Transfer Agreement and the UK Addendum.

§ 07 · Frequently asked
Answers to the questions counsel ask most.
- We are a US law firm and need documents collected from a custodian in London. Who can help?
- We can. Computer Forensics Lab (e-discovery.uk) is an independent UK practice based in Finchley, London, carrying out forensic collection across England, Wales, Scotland and Northern Ireland, usually within 24 to 72 hours of instruction. We collect from laptops, mobiles, Microsoft 365, Google Workspace, Slack, Teams and servers, document chain of custody to NPCC digital-evidence guidelines, and deliver to your review platform or ours in a load-file format your vendor can ingest.
- Can you produce to FRCP standards?
- Yes. We produce single-page TIFF or PDF with searchable text, native files for spreadsheets and structured data, Bates or control numbering, and a DAT or Relativity-compatible load file carrying the agreed metadata fields. We work to the ESI protocol as negotiated, including the treatment of families, redactions, privilege logs and de-duplication scope, and we will attend a meet and confer to agree the specification before collection starts.
- How do we transfer UK personal data to a US court proceeding under UK GDPR?
- Three questions have to be answered: the lawful basis for processing, the basis for restricted transfer, and data minimisation. In practice the transfer is usually made under the UK International Data Transfer Agreement or the UK Addendum to the EU Standard Contractual Clauses, supported by a transfer risk assessment, unless the recipient is certified under the UK Extension to the EU-US Data Privacy Framework. We filter, minimise and where necessary pseudonymise in the UK before anything leaves the jurisdiction, and document the process so it can be explained to a UK regulator or a US court. This is a description of practice and not legal advice on your matter.
- How does a Section 1782 application work for evidence located in England?
- Section 1782 runs the other way: it allows a US federal district court to order discovery from a person found in its district for use in a foreign proceeding. Where a US court needs evidence held in England and Wales, the route is usually a letter of request under the Hague Evidence Convention, issued by the US court and given effect by the English High Court under the Evidence (Proceedings in Other Jurisdictions) Act 1975, or voluntary cooperation from the party or witness. We support both: scoping what is realistically obtainable, giving evidence about collection methodology, and executing the collection once the order or agreement is in place.
- Do you work in US time zones?
- Yes. Our working day covers the whole of the US East Coast business day and the West Coast morning. Urgent collections are scheduled to suit your deposition or production deadline rather than ours, and we report daily during active collection.
- Can your expert testify in a US deposition?
- Joseph Naghdi has given expert evidence in UK civil and criminal proceedings and can give evidence remotely in US depositions and hearings on collection methodology, authenticity, chain of custody and the limits of what digital evidence supports. Scope, availability and terms are agreed in writing before instruction.
- Which review platform do you use?
- Relativity, hosted in the UK, and we can also work directly inside your firm's tenancy. Where you prefer to review in a US platform, we collect and process in the UK, apply the agreed minimisation, and export in the format your platform requires.
- What are the common pitfalls in UK to US cross-border discovery?
- Collecting first and asking about transfers afterwards; treating a UK employee's personal device as freely collectable; over-collecting so that the transfer cannot be justified as minimised; ignoring works-council or employment-law constraints for custodians elsewhere in Europe; agreeing an ESI protocol that assumes US-style metadata fields that the UK source systems never carried; and leaving privilege review until after the data has crossed the Atlantic.
