Use case · Legal
A citation should come with the source it came from.
Courts keep finding filings that cite cases that do not exist. The rule they apply is simple: every citation must be read and checked, however it was produced.
What is happening
This year in court.
- Heavy sanctions. A US federal appeals court reportedly found more than two dozen fake citations in one appeal and fined each lawyer $15,000. (reported by Exterro, March 2026)
- Even large firms. A major law firm apologised to a bankruptcy judge for AI-made errors in a filing. (reported by Bloomberg Government, April 2026)
- Confidentiality. A federal judge ruled that a defendant's own conversations with an AI about his case were not privileged. (reported by Orrick, March 2026)
The question
What a supervising lawyer needs to know.
"Which sources did this draft actually come from, and where did our client's material go?"
What a receipt adds
The draft carries its sources.
- What it opened: the address of every source the AI actually fetched, recorded as it happened. A citation with no fetched source behind it stands out.
- Where the material went: the rules in force say which services the AI could reach, and the record shows what it reached.
- Who approved the work and exactly what was asked.
- Bound to the draft: change one byte and the check fails.
Honest limits
What it does not do.
A receipt does not read the case for you, and it does not prove a citation supports your argument. A lawyer still checks every citation; the receipt tells them which ones the AI actually saw.
