Why Lawyers Need an AI Citation Checker
Generative AI is transforming legal research, but AI models frequently hallucinate citations. When ChatGPT, Claude, or other AI tools cite cases that don't exist, lawyers risk:
Ethical Violations
Submitting briefs with fake citations may violate Rule 3.1 (Meritorious Claims and Contentions) and Rule 3.3 (Candor Toward the Tribunal) of the Model Rules of Professional Conduct.
Credibility Damage
Courts are increasingly sanctioning lawyers for AI-generated hallucinations. One fake citation can undermine your reputation with the court and opposing counsel.
Malpractice Risk
Relying on non-existent legal authority could constitute negligence if it causes client harm. Proper verification is essential.
Wasted Time
Manually verifying every AI-generated citation is time-consuming. CiteClear helps you focus verification efforts on the most suspicious entries first.
