Third-party disclosure redaction is the removal of personal data from records a non-party produces, whether under a CPR Part 34 witness summons compelling attendance and production at a hearing, or under a CPR 31.17 order for disclosure against a person who is not a party. anonym.plus runs locally, so its own data and that of others stay protected regardless of which route was used.
When this applies
A witness summons under CPR 34.2 pulls files from a bank, employer, or supplier for a hearing, while a CPR 31.17 order is the separate pre-trial route used when the documents themselves — not testimony — are what is needed early. Either way, those documents hold PII for many people with no role in the case, all of which needs clearing.
How anonym.plus handles it
- Load the summonsed files into anonym.plus on your device.
- Local OCR reads scanned statements and forms.
- The tool flags names, accounts, and IDs across the set.
- Confirm the flags for everyone named in the files.
- Redact or mask each confirmed value.
- Save the clean output on your device.
What you need to provide
- The files (PDF, DOCX, XLSX, or scan).
- An operator; Redact for full removal of outside data.
- Optional rules to keep the responsive fields.

Limitations & cautions
Summonsed files can name many uninvolved people. Bank and employer paperwork packs PII into fixed layouts, so confirm every column is mapped. OCR on scanned statements needs a check, since a missed account number exposes an outsider.
Frequently asked questions
Who has to redact a non-party production?
The producing entity, or the solicitor preparing it, should clear PII for people not at issue, whichever route compelled production — a CPR Part 34 witness summons for a hearing, or a CPR 31.17 order obtained ahead of trial.
What is the difference between the two routes?
CPR 31.17 lets a party apply for disclosure from a non-party before trial where the documents are likely to support its case or adversely affect another party's. CPR 34.2 witness summonses instead compel a person to attend and bring documents to a hearing.
Can it read scanned bank statements?
Yes. Local OCR reads scans, so account numbers in image files are caught before the set changes hands under either route.
