Family Court Bournemouth · Mar 5, 2026
What happened in this matter?
The court found that a self-represented litigant misled the court by submitting a skeleton argument containing fabricated case law and misrepresented statutory authorities generated by an AI tool. The litigant failed to verify the accuracy of the AI output, leading to wasted judicial and party resources. The court rejected the litigant's attempt to avoid responsibility for these errors.
- Why the court cared
- Fabricated: Case Law | Skeleton argument contained citations that did not relate to the cases named; advocates agreed several citations/propositions were erroneous and the court identified these as AI-generated fabricated case law. || Misrepresented: Case Law | Some cited authorities were existing cases or statutes that did not support the propositions advanced—misattribution of precedent and statutory provisions traced to AI output. || Misrepresented: Legal Norm | Statutory provisions were cited in support of propositions they did not establish, attributed to AI assistance without verification.

Why this matter is tracked
In a Family Court proceeding, a self-represented litigant, who holds herself out as a lawyer, submitted a skeleton argument containing multiple AI-generated citations and propositions. The court identified that several cited cases were fabricated, while other cited authorities or statutory provisions did not support the propositions for which they were advanced. The court noted that the litigant failed to verify the AI-generated output, resulting in the court and other parties being misled and requiring additional time and costs to cross-check and correct the errors. The judge emphasized that all parties, whether represented or unrepresented, have a duty not to mislead the court, and subsequently published the judgment to highlight the risks of unverified AI use in legal submissions.
