# AI & RAG Consulting for Law Firms and Legal Teams

**Summary:** Rubra builds retrieval systems for law firms and in-house legal teams: contract analysis, precedent search, regulatory monitoring and matter research, engineered so that every assertion carries a verifiable citation and the system refuses rather than guesses.

## Where I see this working

- **Contract review and clause extraction.** Pull specific clauses, obligations and deviations from a standard across a contract portfolio, with the exact source passage attached to every finding.
- **Precedent and matter search.** Find prior work on comparable facts across the firm’s own document management system, which is institutional knowledge that currently depends on who happens to remember it.
- **Regulatory monitoring.** Track changes across regulators and map each change to the client obligations and internal notes it affects.
- **Due diligence support.** First-pass review across a data room, flagging what a lawyer needs to read rather than pretending to conclude.
- **Multilingual document review.** Cross-lingual retrieval where a query in one language must return the relevant document in another, which is routine in Belgian, Swiss and EU institutional practice.

Legal is the sector where retrieval quality and citation integrity matter most,
and where the consequences of getting them wrong have been most public.

## Citations are a correctness requirement

In most applications, a wrong citation is embarrassing. In legal work it is
sanctionable. So the system is built so that fabrication is structurally
impossible rather than statistically unlikely:

- The model may only cite from passages actually retrieved in this request.
- Every citation is resolved and validated against the retrieved text before the
  response is returned.
- An unresolvable citation fails the response rather than degrading it.
- Refusal is a designed, measured behaviour. The system says the corpus does not
  cover a question rather than assembling something that reads as if it does.

## Confidentiality has to be architectural

Matter-level access control is enforced at retrieval time, so a passage the user
is not entitled to read is never retrieved, never enters the prompt, and cannot
appear in an answer. Where the firm requires it, inference runs inside the
firm's own infrastructure and nothing leaves the tenancy.

## Where the value is

The highest-return use case in most firms is not sophisticated: it is finding
the firm's own prior work. Decades of precedent, memoranda and negotiated
positions sit in a document management system that is nearly impossible to
search usefully, and the knowledge of what is in there lives with a handful of
senior people.

Making that corpus properly retrievable is a lower-risk, higher-payback project
than anything involving drafting, and it is the one that partners notice.

## Frequently asked questions

### How do you prevent an AI system from fabricating case citations?

By making citation a retrieval operation rather than a generation one. The system may only cite documents it actually retrieved, every citation is validated against the retrieved passage before the answer is returned, and any citation that cannot be resolved fails the response rather than being shown. Fabricated citations happen when a model is asked to recall from training; I never ask it to.

### Is client-confidential material safe in these systems?

It is if the architecture is built for it: matter-level access control enforced at retrieval time, no data leaving your jurisdiction or your tenancy where required, contractual zero-retention with the model provider, and full audit logging of what was retrieved by whom. I have built systems where inference never leaves the firm’s own infrastructure. The safeguards need to be architectural. A policy that says do not paste client data into a chatbot is not a control.

### Will this replace junior lawyers?

Not in what I have built, and I would be sceptical of anyone claiming otherwise. What it changes is the shape of the first pass: instead of reading two hundred documents to find the twelve that matter, a junior reads the twelve and checks the reasoning on the rest. The judgement work remains, and the verification burden is real. A system that produces plausible-looking output nobody checks is worse than no system.
