Date-of-birth redaction is the reduction of a full birth value in a court filing to the least detail the case needs. UK GDPR Art. 5(1)(c) points that way, but the rules sometimes pull the other: CPR PD 16 requires a personal injury claimant's date of birth in the particulars of claim. anonym.plus finds each one on your device and reduces it to the chosen form.
When this applies
A filing may print the full value in the heading, in exhibits, and in quoted records. It can carry procedural weight. CPR 21.1(2)(b) makes a person under 18 a child, and s.28 Limitation Act 1980 can run time from a claimant's eighteenth birthday. Decide what each value is doing before you cut it.
How anonym.plus handles it
- Open the papers in anonym.plus on your device.
- The tool flags a full birth value tied to a person.
- Local OCR reads dates printed on scanned ID cards.
- Apply Replace to keep only the four-digit year.
- Confirm no full value remains anywhere.
- Save the clean papers locally.
What you need to provide
- The filing and exhibits (PDF, DOCX, scan).
- The Replace operator set to keep the year only.
- Optional allow-list for event dates you must cite.

Compliance achieved
- Applies the minimisation duty in UK GDPR Art. 5(1)(c), so only the detail the case needs survives.
- Flags rather than deletes the date of birth CPR PD 16 requires in a personal injury claim.
- Keeps the value that proves whether a party is a child under CPR 21.1(2)(b), a person under 18.
- Preserves the day limitation can turn on, since s.28 Limitation Act 1980 can run time from a claimant's eighteenth birthday.
- Tests re-identification against UK GDPR Recital 26, which asks whether a person can still be singled out.

Limitations & cautions
Not every value is a birth value, and not every one of them can go. CPR PD 16 requires one in a personal injury claim, and s.28 Limitation Act 1980 can make the exact day decisive. Use the allow-list and confirm the context.
Frequently asked questions
Can I remove a date of birth from particulars of claim?
Not always. CPR PD 16 requires the claimant's date of birth in a personal injury claim, so removing it can make the pleading defective. anonym.plus flags the value so you keep it deliberately rather than by oversight.
Why does the exact day sometimes matter?
Because it can drive limitation. Under s.28 Limitation Act 1980 the period can run from the day a claimant who was a child reaches 18, and CPR 21.1(2)(b) defines a child as a person under 18. The year alone may not answer either question.
Will my filing and hearing days be removed too?
Not if you allow-list them. The tool targets a birth value tied to a person, so procedural dates can stay.
