Subrogation anonymisation is the removal of IDs from a recovery case, where an insurer that has paid its own member's claim steps into that member's shoes to recover its outlay from a liable third party. The doctrine rests on the indemnity principle from Castellain v Preston (1883) 11 QBD 380, and where the claim follows a road accident, Road Traffic Act 1988 s.151 is what lets the insurer pursue the third party's own motor insurer directly. Where state benefits were paid to the injured member, the Social Security (Recovery of Benefits) Act 1997 separately requires part of any recovery to go back to the state. anonym.plus works locally and keeps the liability facts intact.
When this applies
A recovery case names the policyholder, the third party, and the accident details the Road Traffic Act 1988 machinery relies on to reach the other driver's insurer. To study recovery rates or train staff, clear those IDs first and keep the liability facts and the cost summary, including any CRU repayment, for review.

Limitations & cautions
Recovery cases bundle legal notes, police data, and medical pages. Check that every page is scanned. An accident date plus a place is a strong clue, so broaden those where your study allows.
Frequently asked questions
Are third parties anonymised too?
Yes. The liable driver or party is a named item in the file in their own right, not just a reference to the member's claim, so they are flagged and swapped along with the member.
Will the liability facts stay usable?
Yes. The fault finding and the cost summary, including any Compensation Recovery Unit repayment under the 1997 Act, stay as written. Only the identifying fields change, so the case still serves recovery-rate analysis.
Why does a road traffic case name a second insurer?
Road Traffic Act 1988 s.151 lets the paying insurer pursue the third party's own motor insurer directly, rather than the driver personally, so that second insurer's details appear in the file. The tool treats those details the same way as the first insurer's own records.
