01 · Problem
An answer you can’t check is a research task.
02 · Approach
A citation is only as good as the three layers under it.
A source link only works if the law is stored in pieces small enough to point at, and if retrieval reliably finds the right piece.
- Structure the law.A legislation CMS for the content team: chapters, parts, articles, annexes and amendments.
- Measure retrieval.An evaluation tool for the AI team: did the right articles come back, and in what order?
- Show the source.Legal chat for lawyers: each claim links to its article, which opens beside the answer.
03 · Solution
Four ways to show a source.
I judged every option by one question: how much work is left for the lawyer between reading a claim and trusting it?
- A link on every claim won.It opens the exact article beside the answer, with the cited text highlighted.
- Then, the version.A correct article in an outdated version is still wrong advice.
04 · Solution · Content
Making the law addressable.
You can only link to an article if the system knows where each article starts and ends. So the content team rebuilds each law as a tree before it’s published.
- Source priority.Tell “the law says” apart from “a guideline suggests”.
- A translation check next to Publish.An unchecked translation is the wrong text.
05 · Solution · Quality
Measuring whether the right article comes back.
06 · Results
The claim-to-source pattern shipped.
07 · Learnings
Trust is a path, not a badge.
Next, I’d test citation density on long answers, measured by time to verify.
- The visible pattern depends on invisible structure.The CMS and the evaluation tool are what made the citation link true.
- Design for the people behind the AI too.The content and AI teams were users of this system as much as the lawyers.
