Rechtbank Noord-Nederland · Nov 19, 2025
What happened in this matter?
The court identified that the plaintiff's counsel submitted fabricated and misrepresented case law, likely generated by ChatGPT, which failed to support the legal arguments. The court explicitly flagged these citations as unreliable and warned against the unverified use of AI tools in legal filings.
- Why the court cared
- Fabricated: Case Law | Pleitnota verwees naar een door de advocaat/geëxposeerde Hoge Raad-arrest aangeduid als 'HR 19 december 2003' en ECLI:NL:HR:2003:AL8444 (NJ 2004/75); rechtbank constateert datumverschil (5-12-2003), ECLI niet terugvindbaar en voorgestelde rechtsregel ontbreekt. || Misrepresented: Case Law | Pleitnota noemde 'NJ 1996/273' aangeduid als arrest van 22 december 1995; rechtbank merkt op dat het gaat om een Arubaanse zaak van 8 december 1995, niet relevant voor verdelingskwesties en onjuist gepresenteerd. || Fabricated: Other | Rechtbank vermoedt dat meerdere vindplaatsen via ChatGPT of vergelijkbare zoekmachine zijn opgedoken en zonder controle in de processtukken zijn overgenomen.

Why this matter is tracked
In a civil dispute regarding the division of an estate, the Rechtbank Noord-Nederland identified that the plaintiff's counsel submitted a pleading containing fabricated and misrepresented case law. The court noted that citations, including a purported Hoge Raad judgment (ECLI:NL:HR:2003:AL8444), were either non-existent, misdated, or irrelevant to the legal issues presented. The court explicitly suspected that these citations were generated via ChatGPT or a similar AI tool and included in the filings without verification. While the court rejected the plaintiff's primary claims regarding the division of property, it partially granted a subsidiary claim for payment. The court emphasized the necessity of verifying all legal authorities against official sources like rechtspraak.nl to prevent the submission of AI-hallucinated content.
