What changes when it is legal services

Permission-aware retrieval is not optional in an enterprise. If a user cannot open a document in SharePoint, the assistant must not quote it. We enforce that at the retrieval layer, not in the prompt.

In legal services, privilege and confidentiality mean data handling is scrutinised more than model performance. That single fact reshapes how rag & knowledge retrieval has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is billing narrative drafting, usually integrated against e-discovery platforms. We start from the constraint, not the capability, what the system must never do, who signs off, and what happens when it is wrong.

Multi-model by default, so a provider outage is a routing decision rather than an incident. We hand over with runbooks, tests and a team that knows how it works, not a dependency.

Questions from this sector

Does using AI risk privilege?

Not if the deployment keeps data inside your control, on-premise or a dedicated tenancy with no training on your content. That is the arrangement we build by default for legal work.

Can it be trusted on case law?

Only with retrieval grounding and citations to real sources. Unguarded models fabricate citations, which is precisely why we never ship legal work without source verification.

RAG or fine-tuning?

RAG for knowledge that changes and must be cited; fine-tuning for style, format and task behaviour. Most production systems use RAG for the facts and light fine-tuning or few-shot prompting for the form.

How accurate will it be?

We build a labelled question set from your domain and report retrieval precision and answer accuracy against it. That number is the deliverable. We do not ship a system whose quality nobody has measured.

Can it respect our existing permissions?

Yes. Retrieval is filtered by the user's actual entitlements, so the assistant can never surface a document the user could not already open.

RAG & Knowledge Retrieval for legal services, worth a conversation?

Tell us the workload and the regulation it sits under. We will tell you what is realistic.
