In re: IMO the Estate of Joseph L. Weddington Jr. — Delaware Court of Chancery, 15 January 2026
The Delaware Court of Chancery flagged incorrect case citations in a petitioner’s exceptions brief, noting possible use of generative AI. The judge issued a direct warning that failing to verify GenAI-prepared material submitted to court ‘is harmful to the legal system.’
Why it matters: Estate and probate proceedings are now within the AI hallucination risk zone. Delaware Chancery — one of the most respected courts in US corporate and estates law — has formally put parties on notice about unverified GenAI submissions.

Background
Complex estate proceedings arose following the death of Joseph L. Weddington Jr. A petitioner sought multiple forms of relief including injunctive relief, declaratory judgments, and damages relating to challenged estate items and asset retitling. When filing exceptions to the court’s report and recommendation, the petitioner’s brief contained several case citations that the court found to be incorrect. The court raised the possibility that generative AI was used in preparing the exceptions.
The AI Issue
The court had to address the petitioner’s exception brief while noting that it contained incorrect citations. The judge expressly stated uncertainty about whether GenAI was used to prepare the brief — but used the opportunity to warn all parties: failing to verify the accuracy of GenAI-prepared material submitted to court is harmful to the legal system. This is one of the first Delaware Chancery warnings about GenAI in estate proceedings.
- The court noted the petitioner’s brief contained ‘several incorrect citations to case law’ [fabricated or erroneous authority].
- The court explicitly acknowledged it was ‘not sure if the Petitioner used generative artificial intelligence’ — but warned against unverified GenAI submissions regardless [precautionary warning].
- The court described failing to verify GenAI-prepared material as ‘harmful to the legal system’ [institutional harm framing].
- The warning applied to ‘the parties’ generally — signalling that both sides should audit their AI-generated submissions [bilateral duty].
- Estate and probate matters are confirmed as within the AI hallucination risk zone [category expansion].
“I am not sure if the Petitioner used generative artificial intelligence (‘GenAI’) to prepare the exceptions, but the parties should take note that failing to ensure the accuracy of material prepared with GenAI and submitted to the court is harmful to the legal system.”

The India Angle
Indian Law Equivalent: Under Rule 15 of the Bar Council of India Rules and the Contempt of Courts Act, 1971, submitting fabricated or non-existent case citations before any Indian court constitutes professional misconduct and contempt. The duty to verify cited authorities is absolute — AI does not create an exception.
Bar Council Rules: BCI Rule 15 (duty not to mislead the court) and Rule 33 (duty to conduct cases with integrity) are directly engaged when AI-generated hallucinated citations are filed. Disciplinary proceedings before the State Bar Council can result in suspension or removal from the roll.
Practical Advice for Indian Advocates: Verify every AI-generated citation on SCC Online, Manupatra, or IndianKanoon before filing. No AI tool — ChatGPT, Claude, Gemini, or any Indian legal AI — reliably produces accurate citations. Treat AI output as a starting point for research, not a final product.
Quick Takeaways
- Delaware Chancery — a court that sets standards for US corporate and estates law — has now formally warned against unverified GenAI submissions.
- Even uncertainty about AI use (the court was ‘not sure’) is enough to trigger a formal judicial warning on the record.
- Estate and probate practitioners in India must apply the same verification standard to AI-generated citations in succession and testamentary proceedings.
