CiteShield uses advanced AI to verify every legal citation in your briefs. Catch fabricated cases before they reach the court.
Pay per document. No subscription required.
Since 2023, lawyers have faced sanctions and public embarrassment for submitting briefs with fabricated case citations. Whether from AI tools or simple research errors, bad citations can derail cases and careers.
Upload, verify, and proceed with confidence.
Upload a PDF, Word document, or paste text directly. We support briefs, motions, and memos up to 50 pages.
We extract every citation, verify it exists in legal databases, check if it's been overruled, and confirm the case actually says what you claim it says.
Receive a detailed report with verified citations, flagged issues, and suggested corrections. Export as PDF or CSV.
Most tools just check if a case exists. We go further with comprehensive verification that protects you from Rule 11 sanctions.
We extract what you claim each citation supports, then analyze the actual case holding to verify it matches. Flags mismatches before they become sanctions.
Example catch:
Brief claims: “Standing established per Smith v. Jones”
Actual holding: Smith v. Jones is about contract formation, not standing
Direct quotes must appear verbatim in the source. We use fuzzy matching to catch alterations, omissions, and fabrications—even accounting for OCR errors.
Example catch:
Brief quotes: “conduct was malicious”
Source says: “conduct was not malicious”
We check if your cited cases are still good law. Flags overruled, abrogated, or superseded precedent before you rely on it.
Example catch:
Citing: Roe v. Wade (1973) for constitutional right
Status: Overruled by Dobbs v. Jackson (2022)
Validates U.S.C., C.F.R., and California code citations. Catches wrong section numbers and repealed statutes with links to official sources.
Example catch:
Brief cites: 42 U.S.C. § 1983.5
Problem: Section 1983.5 does not exist
