Seal the record.
Audit every decision.
Cryptographic audit infrastructure for regulated UK law firms. Hash-seal the records you must keep. Audit every retention and erasure decision. Compliantly destroy only what should be destroyed, only after retention expires.
The SRA requires records that cannot be altered.
UK GDPR requires permanent erasure on request.
Every regulated firm lives with this structural conflict. Accounts Rules mandate audit trails that can withstand seven years of scrutiny. Article 17 of UK GDPR mandates erasure on client request. Nexum addresses this by leaving the mandatory record untouched in your practice management system, while providing the cryptographic verification, decision-audit, and compliant lifecycle layers around it.
Seal. Audit. Comply.
Every document and compliance event is hash-sealed into an append-only Merkle chain. Each record gets a unique cryptographic fingerprint that proves it existed in exactly this form at exactly this time.
Every retention decision, access event, and lifecycle action is recorded with full actor context: who did it, when, and why. Tampering with any record breaks every downstream hash and is instantly detectable.
When a record's retention period expires and the firm's COLP authorises destruction, Nexum cryptographically destroys what it encrypted (internal metadata and payload copies) and issues a key-destruction certificate. The mandatory record itself stays in your PMS throughout.
Works with the tools your firm already uses.
Audit immutability. Compliant retention lifecycle.
