AI Cite Check
Definition
AI cite check is an automated system that verifies the accuracy and validity of legal citations in a document. It confirms that cited cases exist, checks that quoted language matches the source, verifies that holdings are accurately represented, and flags authorities that have been overruled, reversed, or otherwise undermined.
Citation accuracy is a fundamental requirement of legal practice. Courts rely on cited authorities to evaluate legal arguments, and inaccurate citations undermine a lawyer's credibility and can result in sanctions. Traditional cite checking is a manual, labor-intensive process: lawyers or legal assistants must look up each citation, verify the quoted language, confirm the holding, and check the case's subsequent history.
AI cite checking automates this process by independently verifying each citation in a document. The system checks that the cited case or statute exists, confirms that any quoted language matches the source, evaluates whether the proposition attributed to the authority is accurate, and verifies that the authority remains good law. Each citation receives a confidence score and any issues are flagged for attorney review.
The importance of AI cite checking has increased dramatically with the adoption of AI drafting and research tools. Because language models can hallucinate citations, any document that has been touched by AI requires particularly rigorous citation verification. AI cite checking provides a systematic way to catch these errors before they reach a client, opposing counsel, or the court.

Citation Verification
Citation verification is the process of independently confirming that legal citations in a document are accurate: that the cited authorities exist, that quoted language matches the source, that holdings are correctly represented, and that the authorities remain good law. In AI-assisted legal work, automated citation verification is essential to catch hallucinated or inaccurate references before they reach a court or client.
ResearchGood Law Check
A good law check is the process of verifying whether a cited legal authority remains valid and has not been overruled, reversed, superseded by statute, or otherwise undermined by subsequent legal developments. AI-powered good law checks automate the citator function traditionally performed by Shepard's Citations (Lexis) or KeyCite (Westlaw).
ResearchAI Legal Citations
AI legal citations are case references, statutory citations, and other legal authority references generated by AI systems in the course of legal research or drafting. The accuracy and verifiability of AI-generated citations is a central concern in legal AI because language models can produce citations that appear well-formed but reference non-existent authorities.
AI ConceptsAI Hallucination in Legal
An AI hallucination occurs when a language model generates text that appears authoritative but is factually incorrect, such as fabricating case citations, inventing statutes, or misrepresenting holdings. In legal practice, hallucinations carry professional responsibility implications because lawyers have a duty to verify the accuracy of every authority they cite.
