Use case · Law firms and legal departments

Every case walled off, every document cited, the law as of the right date.

Letters, formal notices, expert reports, judgments: Ts-Knowledge indexes them along their natural structure, extracts parties, courts and events, and places French law right alongside — as it stood on the date of the facts. Your AI searches it all, without ever crossing the wall around a case.

What a generic AI can't do for a law firm

Among two hundred other cases, the Vasselin law firm is handling SCI Les Tilleuls v. Bâtiloire, a building contractor: a leaking terrace, an expert assessment, a formal notice, a judgment. Three pitfalls come up in every case.

An answer cut in half“What deadline did the formal notice give?” Split at random, the letter puts the demand in one excerpt and the deadline in another: the AI only gives half an answer.

How it's organized

One space per case, with the law right alongside

Each case is a space: its documents, its permissions, its knowledge. Nothing connects two cases — not a search, not an entity, not a key that hasn't been given access to both. French law, meanwhile, doesn't need to be imported anywhere.

SCI Les Tilleuls v. Bâtiloire

Formal notice, expert report, acceptance report, judgment, email exchanges. One space, with its own members and its own keys — no one else's.

The other cases

Each in its own space. A search started in one never surfaces a document from another, and an ID typed in by hand opens nothing.

French legislation

Consolidated codes and statutes from Légifrance — the official French legal database — as a shared library: read-only, by subscription, and kept up to date by the platform.

A library you don't have to build

Several hundred thousand articles, indexed once by the platform and updated from the daily publications of the DILA, the French government's legal publishing office. You add it to your subscription from the catalog, and it's readable right away, alongside your cases.

The law as of the date of the facts

Every article carries its effective and repeal dates. A dated search returns the wording that applied on that day — never two competing versions of the same article.

1 · Find

Documents split along their natural structure

A letter doesn't read like a code, and a judgment doesn't read like an expert report. Each type of document gets its own splitting, so that every excerpt stands on its own — and can be cited.

Letters

A short letter stays whole: demand, deadline and consequence in the same excerpt. A long letter keeps its subject, date, sender and recipient as context for every paragraph.

Expert reports

Cited by section, full path included: “4. Defects › 4.2 Terrace”. A report without headings falls back to its paragraphs, with no invented sections.

Court decisions

Recitals, grounds, operative part. The operative part never shares an excerpt with the grounds: an argument the court rejects never reads as its ruling.

“I don't know”Was Bâtiloire insured in 2021?: Not enough evidence: no document in the case file says so. Your AI flags it — so you know which document to request, instead of reading an imaginary insurance certificate.

Hybrid search combines meaning and exact wording: an article number, a party's name or a document reference finds its passage just as well as a question in everyday language.

2 · Understand

Parties, facts and their timeline, with the documents to prove it

With the “Legal” template, Ts-Knowledge reads a case's documents and extracts what they assert: who the parties are, who represents whom, which court is hearing the case, which instruments were signed, which events took place — each tied to the document, page and sentence that establish it.

Parties

Individuals and legal entities, their role in the case, their addresses and registration numbers — with the document that mentions them.

Relationships

Party to, represents, opposes, judged by: who stands against whom, and before which court.

Timeline

Signing, formal notice, hearing, judgment, payment: the case's events in order, each with its document.

Documents that disagree

Two documents that give the same company two different registration numbers are flagged, ranked by severity, and never settled for you.

The Tilleuls case timeline

Rebuilt from the documents, with no re-keying. Each line points back to the passage that proves it: at a hearing, you know where every date comes from.

A case file contains many amounts, and that's normal: the legal vocabulary accepts several of them. Declare a “claimed amount” dimension with a single value, and two documents that don't claim the same sum get flagged.

The Knowledge Snowflake

What about a Snowflake for a case?

The Knowledge Snowflake arranges a project into facets, based on a profile: today there is one for fiction series and one for e-commerce. There isn't one yet for a legal case, and we'd rather say so than show you a map that doesn't exist.

What a case already has

The graph of its parties, documents and courts, plus its timeline. Your agent can also ask for a case's map: without a profile, it returns that graph, without facets.

For an in-house legal team

If you manage the rules of an online store — terms of sale, return policy, commitments to customers — the “E-commerce” profile already arranges rules, decisions and partners into a Snowflake, department by department. See the e-commerce use case

The guarantees a law firm expects

One key per case: restricted to the spaces you choose, with only the permissions you check — search and excerpt reading by default.
The library is read-only, for everyone, with no exceptions: nobody adds or changes anything in it.
What isn't opened doesn't exist: a case outside the key's scope responds exactly like a case that doesn't exist.
Ts-Knowledge writes nothing: it provides documents and citations, and your agent does the writing.
