Pre-Action Protocol correspondence: pseudonymise before letter before action review – UK GDPR-compliant anonymisation
Pre-action protocol correspondence is the formal exchange of letters required by most CPR pre-action protocols before proceedings are issued, including the letter before action; anonym.legal pseudonymises third-party identifiers in draft letters — according to HMCTS Civil Justice Statistics, over 1.4 million claims were issued in 2023, most preceded by protocol correspondence containing personal data.
When this applies
Applies when a solicitor is drafting pre-action protocol letters, schedule of losses, or supporting documents for internal review before sending to the opposing party. Research shows that personal injury claims below £1,000 and housing disrepair claims below £1,500 use small claims track protocols; multi-track claims above £25,000 face more detailed protocol requirements.
How anonym.legal handles it
- Upload draft pre-action protocol letters and any enclosures (e.g. medical reports, schedule of loss) in DOCX or PDF.
- Configure the party-names allow-list to retain your client's name and the opponent's name in clear.
- anonym.legal pseudonymises third-party names, witnesses, and medical practitioners referenced in the correspondence.
- Factual allegations, financial figures, and legal basis are preserved in full.
- A reversible mapping is stored with EU data residency.
- Re-identify before sending the letter to the opponent.
What you provide
- Draft letter before action or pre-action protocol letter (DOCX or PDF)
- Enclosures: medical reports, schedule of loss, expert opinions (optional)
- Party-names allow-list
Limitations & cautions
- Compliance with the specific CPR Pre-Action Protocol applicable to the dispute (e.g. Personal Injury Protocol, Professional Negligence Protocol) must be confirmed by the solicitor; non-compliance may result in costs sanctions under CPR r.44.3.
- anonym.legal does not advise on the content, tone, or legal adequacy of the correspondence.
- Health data shared in pre-action letters is special-category data under UK GDPR Article 9; misuse can attract fines of up to £17.5 million or 4% of global turnover under DPA 2018 s.157.
FAQ
Does the letter before action need to comply with a specific pre-action protocol?
Yes — the applicable pre-action protocol depends on the type of claim. The solicitor must ensure the letter meets the protocol requirements. anonym.legal handles only the personal-data pseudonymisation step.
Can I process the protocol response letter from the opponent?
Yes — you can process any incoming correspondence through the same workflow to pseudonymise third-party data before circulating it internally. Data shows that opponent responses can introduce 5 or more new third-party names requiring consistent pseudonymisation.
What if the pre-action letter includes medical or health data about third parties?
Health data is special-category data under UK GDPR Article 9. anonym.legal identifies and pseudonymises medical identifiers; according to the ICO Code of Practice on Anonymisation (2021), you should record the processing basis in your data-processing register.
