Quick checklist
Start with these
Best order
How to organise the first pack
- Put the latest letter, claim, ICO notice or deadline at the front.
- Add a chronology covering discovery, reporting, notification and response.
- Identify the data, parties, roles and people affected at a high level.
- Group technical logs, policies, contracts and processor records separately.
- Add impact, loss, distress, mitigation and settlement evidence last.
Identify The Data Protection Problem
A data breach enquiry may involve a personal data incident, ICO complaint, subject access issue, misuse of private information, confidentiality concern, compensation claim, defence or regulator response.
The first enquiry should say whether the client is an individual, controller, processor, employee, organisation, complainant or proposed defendant.
Core Evidence To Gather
A data protection barrister will usually need the documents that show what happened, who was responsible, what data was involved and what response followed.
- Breach notice, complaint, letter before claim, ICO correspondence or decision.
- Chronology of discovery, internal escalation, reporting, notification and follow-up.
- Description of the personal data, affected people and controller or processor roles.
- Privacy notices, contracts, processor agreements, policies and processing records.
- Incident logs, audit trails, screenshots, emails and technical summaries.
- Evidence of loss, distress, mitigation, remedial steps or operational impact.
- Court papers, settlement correspondence, injunction papers or regulator deadlines.
Reporting And Regulator Context
ICO guidance explains that some personal data breaches must be reported to the ICO and, in some cases, affected individuals. This guide does not decide whether reporting is required in a specific case.
Send the actual ICO guidance relied on, internal assessment and decision record if reporting or non-reporting is disputed.
How A Barrister May Help
Defined work may include advice on duties, evidence, claims, defences, regulator correspondence, settlement, drafting or suitable hearing representation.
Some incidents require technical forensics, DPO input, solicitor support or ongoing incident-response management before legal advice can be scoped.
Avoid delays
What not to send first
- Sending only a complaint without the breach chronology.
- Omitting ICO or court deadlines.
- Leaving out controller, processor or data-subject roles.
- Assuming a quote request pauses limitation, regulator or court deadlines.
Source/review note: ICO guidance on personal data breaches and UK GDPR reporting should be checked before publication and before any case-specific statement. Court, limitation and compensation wording should be reviewed by a data protection specialist.
Editorial status: source and legal review required. No completed legal review is claimed.
