Purportedly AI-Generated False Citations in Arizona Probate Appeal Reportedly Led to Sanctions Against Self-Represented Appellant
Self-represented appellant Jeffrey Kotchka reportedly used purported AI tools to prepare an opening brief in a probate dispute involving his late mother's estate. The Arizona Court of Appeals found six of its eight citations deficient, including two nonexistent cases, and said Kotchka had made no effort to verify them. The court affirmed the appointment of his sister, Kim Dineen, as personal representative, ordering Kotchka to pay her attorney fees attributable to addressing the false citations.
