Artificial intelligence is rapidly becoming embedded in the legal profession—but not without consequences. Over the past year, courts across the United States and beyond have seen a surge in cases where lawyers submitted filings containing AI-generated errors, including completely fabricated legal citations. What began as isolated incidents has now evolved into a systemic issue, raising serious questions about how professionals are using—and misusing—AI tools.
The scale of the problem is accelerating. According to Damien Charlotin, a researcher tracking global legal sanctions related to AI misuse, the numbers are rising sharply.
“Recently we had 10 cases from 10 different courts on a single day,” he said, noting that more than 1,200 such incidents have now been recorded worldwide. The core issue, he argues, is not that AI is ineffective—but that it is deceptively convincing. “We have this issue because AI is just too good — but not perfect.”
Courts are responding with increasingly severe penalties. In one recent case, a federal judge ordered a lawyer to pay over $100,000 in sanctions for submitting AI-generated errors. Despite widespread media coverage and earlier high-profile cases—including fines issued to attorneys for filing fictitious citations—lawyers continue to rely on AI outputs without proper verification. The result is a growing tension between the efficiency AI offers and the professional responsibility required in legal practice.
At the heart of the issue is a longstanding rule: lawyers are fully responsible for everything they submit, regardless of how it was created. Legal experts emphasize that AI cannot replace due diligence.
“Whatever the generative AI tool gives you… you have to read those cases,” said Carla Wale of the University of Washington. “You have to read the cases to make sure what you are citing is accurate.” In other words, AI can assist—but it cannot absolve responsibility.
Looking ahead, the challenge is likely to deepen as AI becomes more integrated into legal workflows. New “agentic” systems promise to handle entire legal processes end-to-end, potentially obscuring the steps where human oversight is critical. Some experts warn this could erode analytical thinking and increase the risk of errors, while others believe the profession will adapt. As Wale put it, “lawyers who understand how to effectively and ethically use generative AI replace lawyers who don’t.” The future of law may not be AI versus humans—but humans who know how to work with AI versus those who don’t.
