# RankShield Legal

> RankShield Legal is a verifiable AI and quantum security platform for law firms. It certifies that every cited authority exists, is quoted accurately, and is still good law before a filing is signed, and it attests that privileged client material never reached a third-party AI model in retrievable form — each result post-quantum signed and sealed to a tamper-evident transparency log you can verify yourself.

The risk
## A fabricated case *looks perfectly real.*
AI invents citations with flawless format and a persuasive holding, for opinions that were never written. Because the format is right, they survive a human skim, and courts are now sanctioning the lawyers who file them.

The checkpoint
## Verify before *you sign.*
RankShield sits between the draft and your signature. Every cited authority is resolved against live case-law for existence, quotation, and good-law standing, so a fabricated case is caught before it reaches the court.

Confidentiality
## Privileged material *never reaches the model.*
Client secrets are withheld, redacted, tokenized, or kept on a local model, and a signed attestation binds the interaction, the approved tool, the policy, and the client's informed consent. A promise becomes proof.

The proof
## Post-quantum signed. *Sealed to a log.*
Each result is signed with NIST post-quantum cryptography and sealed to a tamper-evident transparency log, so it stays verifiable for as long as privilege lasts — which is forever.

Independently checkable
## Don't take our word. *Check it yourself.*
A court, a client, an auditor, or opposing counsel can verify a receipt without an account and without access to your systems. In a profession built on evidence, your AI accountability is evidence too.

Built for your firm
## Enterprise-grade. *Firm-sized.*
The controls a large firm would build in-house, delivered as a checkpoint a small or midsize firm can switch on. Start with the free citation checker, or request early access.

## Check a citation against live case-law
Paste a reporter citation from an AI-drafted brief. We resolve it against a live case-law corpus and tell you whether the case is real. Existence check only — not good-law standing, and not legal advice.

Reporter citation Check
Try a real one like 576 U.S. 644 or a fake one like 999 U.S. 9999.

Resolves against the public CourtListener corpus. Full certification (existence + quotation + good-law, signed and sealed to a transparency log) is part of the RankShield Legal platform. [How certification works →](https://rankshieldlegal.com/citation-certification/)

Why this exists
## In a profession built on evidence, "secure" should be provable.
RankShield began with a personal wake-up call: its founder's own devices and business were attacked, including an AI voice-cloning scam that targeted his family. The lesson was not that AI is dangerous, but that unverifiable systems are. RankShield Legal applies that conviction to law, where unverifiable AI hurts most: fabricated citations, privileged data with nowhere to prove it went, and confidentiality that never expires.

How it works
## From draft to proof, in three steps

1
### Draft as you do now
With or without AI. Nothing changes about how your team works up a filing.

2
### Certify before signing
Every citation is resolved against live case-law and privileged interactions are attested — the checkpoint sits before your signature.

3
### Prove it
Each result is post-quantum signed and sealed to a transparency log a court, client, or insurer can verify independently.

- **What is RankShield Legal?** RankShield Legal is a verifiable AI and quantum security platform for law firms, and the legal pillar of the RankShield Network. Before a filing is signed it certifies that every cited authority exists, is quoted accurately, and is still good law; it attests that privileged client material never reached a third-party AI model in retrievable form; and it seals each result to a tamper-evident transparency log so the proof is independently verifiable. It is a security vendor, not a law firm, and nothing it publishes is legal advice.
- **What is the biggest AI risk for a law firm right now?** The one already producing sanctions: AI-drafted briefs that cite fabricated cases. Public trackers catalog well over a thousand filings worldwide involving AI-hallucinated or misused authorities. It is preventable with a citation check before signature, which is exactly what the platform does. Privileged data leaking into third-party AI tools is a close, quieter second.
- **Does RankShield replace my AI research or drafting tools?** No. Your tools do the drafting and research; RankShield adds a verifiable checkpoint between the draft and your signature and produces the evidence a court or client can check. It is a common accountability layer for the AI tools you already use, not another drafting product.
- **Is RankShield Legal available now?** The two core capabilities — citation certification and privilege-isolation attestation — are live on the RankShield Network, with citation resolution wired to live case-law. We are onboarding design-partner firms, ideally with a KeyCite or Shepard’s citator, before enabling enforce-mode blocking of filings. Forward capabilities like the AI-tool attestation gateway and governance dashboard are clearly labeled as roadmap.
