Quick answer — TL;DR

AI drafting draws on old precedents because everything uploaded goes into the same retrieval pool, and the knowledge team has no way to mark a document as approved, superseded or withdrawn. We build source curation for knowledge lawyers: approval states on precedents and clauses, retrieval limited to approved material by default, retirement that takes effect at once, and visibility of which sources each draft used.

A draft built on last year's clause

A fee earner asks your product to draft a limitation of liability clause for a supply agreement. The draft looks good. The knowledge lawyer who reviews it spots that it is based on the firm's old standard clause, replaced last spring after a change in the firm's approach. The new standard is in your product too. So is the old one, and a third version from a matter where the firm accepted the other side's drafting.

The AI picked the one that best matched the request. Nothing told it which one the firm stands behind.

Why AI drafting ignores the knowledge team

Knowledge lawyers and professional support lawyers maintain a firm's precedents, clause banks and guidance. They know what is current and what has been superseded. In most legal tech products, that knowledge never reaches the retrieval layer the AI draws on.

  • Every document uploaded goes into one retrieval pool, with no status.
  • Superseded precedents are never removed, because nobody wants to delete history.
  • Matter documents with negotiated drafting sit alongside firm standards.
  • The AI ranks sources by similarity to the request, not by authority.
  • Knowledge lawyers cannot see which sources a draft relied on.

What uncontrolled sources cost

Drafts built on outdated or negotiated wording create extra review work at best and, at worst, reach a client before anyone notices. Knowledge lawyers, who are usually the firm's gatekeepers for drafting tools, lose confidence in the product and may restrict it. And the firm's investment in keeping precedents current is undermined by a tool that treats last year's version as equal to this year's.

It also wastes the thing that makes a firm's own precedents valuable. The point of drafting from the firm's material is that it reflects the firm's agreed positions. Without curation, that advantage disappears.

There is also a quieter problem with retrieval pools that grow without limit. The more documents a firm uploads, the more near-duplicates compete for each request, and the less predictable drafting becomes. Fee earners notice that the same request produces different starting points on different days, and they stop relying on it.

How we give knowledge lawyers control

What we build adds authority to your product's sources and puts the knowledge team in charge of it.

  1. Status on every source: approved standard, alternative, superseded, withdrawn, or matter document, set by the knowledge team.
  2. Default retrieval from approved standards only, with alternatives used when a fee earner asks for them, and matter documents only when the user chooses and has access.
  3. Retirement that takes effect at once: marking a precedent superseded removes it from default retrieval immediately, while keeping it for history and audit.
  4. Version links, so a superseded precedent points to its replacement and a draft can say which version it used.
  5. Source display on every draft: which precedents and clauses it drew on, with their status, so reviewers see authority at a glance.
  6. A knowledge team dashboard showing which sources are used most, which superseded ones are still being requested, and which approved ones are never used.

Which precedents are approved and when they change is entirely the knowledge team's call. The product respects their decisions immediately.

The limitation clause, drafted again

The fee earner asks for the same clause. The product draws on the firm's current standard and shows it as the source. The old clause does not appear, because the knowledge lawyer marked it superseded when the new one was approved. The fee earner asks for an alternative for a customer-friendly position, and the product uses the approved alternative, labelled as such. The knowledge lawyer's dashboard shows the new standard is now the one being used, and that a few users still search for the old one, which prompts a note in the firm's knowledge update.

Does your AI know what the firm stands behind?

  • All uploaded documents are treated equally by your AI features.
  • Knowledge lawyers cannot mark precedents as superseded in your product.
  • Drafts do not show which sources they used.
  • Negotiated matter documents are mixed with firm standards.
  • Knowledge teams have asked to restrict your AI features.

FAQ

Frequently asked questions

The questions readers ask us after this guide.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Do knowledge lawyers have to classify every document?

No. Firm standards and alternatives are classified; everything else defaults to matter document or unclassified and is not used by default.

Can individual fee earners override the default?

Yes, where the firm allows it, and the draft records that they did.

What if the firm has no knowledge team?

A partner or practice group lead can do the same job, usually for a smaller set of core precedents.

What do you need from us?

Access to your retrieval and drafting code, your document model, and feedback from knowledge lawyers at your firms.
