RAG for Legal, Finance and Healthcare: What Changes in Regulated Industries
Regulated documents have rules of their own: clauses that must stay together, tables that must add up, and sensitive fields that must never leak. Here is how RAG adapts.
RAG for Regulated Industries
The same retrieval pattern applies everywhere, but each industry adds constraints.
Legal
A clause must stay with its sub-clauses, and a judgment must stay in context. Chunking has to follow legal structure, and every answer needs a citation back to the clause or paragraph.
Finance
Statements and invoices are tables. Totals should be computed from the rows retrieved, not guessed by a model, and account numbers should be protected before they are indexed.
Healthcare
Clinical lists — medications, eligibility criteria — must come back complete rather than as a fragment. Patient data needs protection, and retrieval should support staff without pretending to give clinical advice.
Common requirements
- Permission-aware retrieval with an audit trail
- PII tokenised before embedding
- Deletion that really deletes
- An honest “not found” when the answer is not in the documents
