Why we exist
1,598
Court cases involving AI-fabricated citations as of June 2026 — up roughly 8× in a single year, with new incidents documented nearly every day. Judges are sanctioning the lawyers who filed them, not the tools that wrote them.

The quiet part
Everyone is using AI — and a lot of people are afraid to admit it.
Drafting with AI isn't the risk — filing unverified AI work is. The lawyers getting sanctioned aren't the ones who used AI; they're the ones who couldn't prove they checked it.
Being afraid doesn't protect you.
Avoiding AI just means losing hours your competitors don't. And "I didn't use AI" isn't a defense a judge will test kindly — fabricated citations get found either way.
Being verified does.
Use whatever tools you want. Send us the document before it's filed, and every case it cites gets checked against the record. Safe beats sorry — and verified beats both.
What Lavir does
We find the fake case before the judge does.
Send us the filing. We check each cited case against primary sources: does it exist, does the quote match, does it actually hold what it's cited for. You get a specific diagnostic of anything fabricated or mischaracterized — and a verified record for the matter file once it's clean.

How it works
Three steps. One day.
02
We verify
Every citation, quotation, and holding checked against primary legal sources. Not an AI opinion — a ground-truth check.
03
You file with proof
A diagnostic of anything wrong — then a Lavir Verified record you keep in the matter file as evidence of reasonable verification.
Why Lavir
A shield, not a badge.
The verified record is your paper trail.
Sanctions opinions turn on whether counsel took reasonable steps to verify. A Lavir report documents exactly that — every cite checked, dated, against primary sources — before the filing went out.
We verify workflows, not models.
We don't benchmark or rank AI models. We verify your actual work product against ground truth — whatever tool produced it. Independent, portable, no marketplace, no insurance bundle.
