Verify a Citation

Verify a CitationTrust starts with the authority.

Paste a citation and the AI statement that relies on it. Verity checks whether the authority exists, remains good law, and supports the way it is used.

100% fabrication detection
96.8% overruled recall
0% false leniency

How it works

One citation. One authority record. One independent check.

Verity is the atomic verification workflow inside VariLegal. It independently retrieves the authority and evaluates whether the AI-assisted use is supported by the legal record.

01 Advocate

Resolve the authority

Verity resolves the citation, verifies the case identity, and retrieves the authority record from an independent source.

02 Adversary

Check treatment and support

Verity checks treatment status and whether the cited authority supports the proposition for which it is used.

03 Arbitrator

Audit and certify

The deterministic auditor judges consequence and produces an evidence-backed verification certificate.

Output: Court-defensible PDF certificate with SHA-256 hash, full deliberation trail, and methodology disclosure. Compliant with NDTX, EDMI, and Fifth Circuit AI disclosure requirements.

Tested against the complete set of 225 overruled Supreme Court citations in the Stanford RegLab preregistered dataset. Built entirely on open-source CourtListener data. Three-stage waterfall enrichment. 0% false leniency is the sole pass/fail gate for model upgrades.

The trust layer between AI output and legal reliance.

Draft anywhere. Verify independently with VariLegal before you rely on the citation.
