Holstein v. Holstein
CA Indiana · Jun 16, 2026
What happened in this matter?
The Court of Appeals of Indiana denied the appellee's request for monetary sanctions against the appellant's counsel. While the Court emphasized the duty of candor and the risks of using AI-generated research without verification, it found that counsel's voluntary disclosure and correction of the fabricated citations mitigated the need for formal sanctions.
- Why the court cared
- The Court reasoned that sanctions were not warranted because counsel proactively notified the Court of the errors, sought leave to amend the brief, and the appellee failed to demonstrate prejudice or identify the errors in their initial response.
- Why it matters now
- This case illustrates judicial expectations for attorney due diligence when using AI-assisted research. It highlights that while courts are increasingly vigilant regarding fabricated citations, prompt self-correction and a lack of prejudice can mitigate the risk of monetary sanctions.
Why this matter is tracked
In an appeal regarding child custody, the appellant's counsel included two non-existent case citations and a fictitious quotation in the initial brief. Counsel discovered the errors while preparing the reply brief, notified the Court, and filed an amended brief. The appellee requested $5,000 in attorney's fees as a sanction for the inclusion of these fabricated authorities. The Court of Appeals of Indiana acknowledged the duty of candor and the risks associated with using artificial intelligence in legal research. However, the Court declined to impose monetary sanctions, citing counsel's prompt self-correction, lack of prejudice to the opposing party, and the appellee's failure to identify the errors in the original response. The Court ultimately affirmed the trial court's custody decision.
