TL;DR
South Korea’s National Court Administration published a survey on November 2, 2026, in which judges reported encountering fabricated or distorted legal citations, including nonexistent precedents and real rulings cited inaccurately. The results reflect judges’ experiences, not a count of affected court filings, and the administration is considering procedural-law changes to permit fines.
South Korea’s National Court Administration said a survey of 360 judges found widespread experience with fake or distorted legal citations in court filings, including nonexistent precedents and real rulings represented inaccurately. Published November 2, the results have prompted the court administration to plan proposals for procedural-law changes, including a legal basis for fines.
The survey covered judges at courts of all levels and was conducted from October 6 to 16. Among judges handling civil, family and administrative cases who had encountered false citations, 196, or 80.7%, identified precedents that did not exist; 159, or 65.4%, identified real precedents cited with false content. Respondents could select more than one type.
The often-repeated figure of about eight in ten applies to responding judges in those case areas, not to all 360 survey participants. The Korean daily Kyunghyang Shinmun reported that 243 of all 360 judges, or 67.5%, had experienced fake citations. That figure is not printed in the court administration’s release, though it matches the underlying count described in the source material.
Judges identified both litigants and lawyers as sources of false material. A total of 164 judges (69.5%) said parties themselves had cited it, while 136 (57.6%) said it appeared in documents submitted by lawyers. The release also described fabricated judgments styled like Supreme Court decisions, unfamiliar reasoning paired with Supreme Court case numbers, altered accounts of real rulings, and chatbot conversation or litigation-strategy text pasted into filings.
Pressure for Citation Rules
The findings matter because false citations can make courts and opposing parties spend time checking authorities that do not exist or do not support the argument attributed to them. The National Court Administration said such material creates an unnecessary verification burden for the opposing party and can hinder the timely progress of trials.
Judges showed strong support for an institutional response: 91.7% said one was needed, and 64.8% described it as very necessary. The most frequently selected measures were a legal basis for fines (61.4%), a duty to verify cited precedents (61.1%) and a duty to disclose AI use (60.6%). These are survey responses, not rules already in force.
The issue is not limited to whether a chatbot produced an error. A filing can contain a nonexistent authority, misstate a real ruling, or include unedited AI output. If courts adopt new duties or penalties, the rules will shape how lawyers and self-represented parties check and disclose material prepared with AI tools. The survey does not establish how often these errors occur across all filings.

What the Court Survey Measured
The National Court Administration is the administrative arm of South Korea’s Supreme Court. Its November 2 release, issued through the Judicial Support Office, was titled “Results of the survey on citations of AI-generated false precedents and similar material.” It described the inquiry as a response to concerns that AI hallucinations can generate false or nonexistent legal citations.
The survey records what judges said they had encountered. It does not count individual filings, verify every incident independently or establish that AI caused each false citation. The court administration did not state how many judges were invited, and the supplied material does not give the full question wording. Those limits matter when interpreting percentages and claims about prevalence.
The source material also flags a translation error in an English-language news report. The Korean release says 164 judges identified the parties themselves as a source of false material. It does not say those judges admitted to citing false precedents themselves. The distinction illustrates why the original wording matters when reporting the survey.
Limits of the Survey Evidence
The results do not show the share of court filings containing fake citations, because the survey asked judges what they had experienced rather than examining a defined set of documents. The release also does not say how many judges were invited or provide the complete questionnaire, limiting what can be concluded about response rates and how answers were framed.
It is also unclear from the published information how many cases involved AI specifically, as opposed to false citations from other sources. The survey describes examples associated with AI-generated material, but does not establish the cause of every incident. The administration’s proposal is still planned; the survey itself does not change court rules or impose penalties.
Proposed Changes to Procedure Acts
The National Court Administration plans to propose amendments to South Korea’s Civil and Criminal Procedure Acts that would provide a legal basis for fines over false citations. The survey also records support for verification and AI-disclosure duties, but the supplied material does not say whether those measures will be included in draft legislation.
No timetable, draft text or legislative decision is provided in the November 2 release described here. The next developments to watch are the administration’s formal proposals and whether lawmakers take them up. Until then, the reported survey results are evidence of judges’ experiences and preferences, not a new binding standard for court filings.
Key Questions
What did South Korea’s judges report?
Judges reported encountering nonexistent precedents, real rulings cited with false content and other inaccurate legal material in court filings. The survey measured reported experience, not the proportion of all filings affected.
Does the eight-in-ten figure apply to all 360 judges?
No. The about-80% figure refers to responding judges handling civil, family and administrative cases who reported experience with false or nonexistent precedents. Kyunghyang Shinmun reported that 243 of all 360 respondents, or 67.5%, had encountered fake citations.
Did judges say lawyers were involved?
Yes. In the survey, 136 judges (57.6%) identified lawyers acting as representatives or defense counsel as a source of false material. A separate 164 judges (69.5%) identified the parties themselves. Respondents could select more than one source.
Are fines or AI-disclosure rules already in force?
The survey did not enact new rules. The National Court Administration said it plans to propose procedural-law changes that would allow fines; judges also supported verification and disclosure measures. The timing and final content of any legislation are not stated.
