TL;DR
South Korea’s National Court Administration published a survey on November 2, 2026, reporting that about 80% of responding civil, family and administrative judges had encountered false or nonexistent precedent citations. The survey records judges’ experiences, not the prevalence of fake citations across all court filings; the administration says it plans to propose procedural-law changes that could allow fines.
South Korea’s National Court Administration published survey results on November 2 showing that about 80% of responding civil, family and administrative judges had encountered false or nonexistent precedent citations in court filings. The administration said it plans to propose changes to procedural laws, including a legal basis for fines, as judges report that fabricated citations create extra work and can slow proceedings.
The survey drew responses from 360 judges at courts of all levels between October 6 and 16, 2026. The court administration’s release says the headline figure applies to responding judges handling civil, family and administrative cases. The Korean daily Kyunghyang Shinmun reported that 243 of all 360 respondents, or 67.5%, said they had encountered false citations. The survey measures what judges said they had seen; it does not establish how often false material appears across all filings.
Among judges who reported encountering false citations, 196 (80.7%) identified precedents that did not exist, while 159 (65.4%) identified real precedents cited with false content. Respondents could select more than one category. The survey also recorded reports of false or nonexistent statutes and legal publications, though at lower rates. The court administration said such citations can impose an unnecessary verification burden on the opposing party and hinder the speedy progress of trials.
Judges identified both self-represented parties and lawyers as sources of false material. In the survey, 164 judges (69.5%) named the parties themselves, and 136 (57.6%) named lawyers representing or defending parties. Those figures concern respondents’ reports of who submitted the material; they do not establish intent or whether every instance resulted from AI use.
The court administration’s release describes examples including fabricated judgments formatted to resemble Supreme Court decisions, real case numbers paired with reasoning that could not be found, and genuine rulings represented as saying something different from their holdings. It also cited filings containing text from AI conversations or litigation-strategy notes apparently copied without editing. The release links the problem to AI-generated hallucinations but does not say that every false citation in the survey came from AI.
How False Citations Burden Trials
Courts and opposing parties may need to spend time checking whether a cited ruling exists and whether it supports the argument made in a filing. The administration says that work can add verification burdens and affect the pace of trials. Fabricated authorities can also make it harder for judges to assess arguments using a reliable record.
The results place the issue beyond a concern about errors by unrepresented litigants: judges also reported false material in documents submitted by licensed lawyers. That does not show how frequently lawyers make such errors, why they occur, or whether they are deliberate. It does, however, give the administration a basis to consider clearer expectations for checking citations and disclosing AI use.
Most respondents favored an institutional response. The administration’s results list fines, a duty to verify citations and disclosure of AI use among the most selected measures. Any new rules would affect how parties and legal representatives prepare court documents, but the survey alone does not determine what requirements lawmakers will adopt.

What the Survey Actually Measures
The National Court Administration is the administrative arm of South Korea’s Supreme Court. Its November 2 release was titled “Results of the survey on citations of AI-generated false precedents and similar material.” It said the survey was prompted by concerns that AI hallucinations were producing citations to nonexistent or false legal authorities. The release reported that 91.7% of respondents favored an institutional response, with 64.8% describing one as very necessary.
The reported percentages have different denominators. The often-repeated “about 80%” applies to judges handling civil, family and administrative matters who responded to the relevant question. The figure of 67.5% across all respondents comes from Kyunghyang Shinmun’s report of 243 out of 360. Within the group reporting experience, 196 of 243 is 80.7% for nonexistent precedents. Keeping those groups separate matters: the survey does not show that eight in ten court filings contain fake citations.
Several respondents selected more than one answer, so category totals are not mutually exclusive. The administration’s release also does not state how many judges were invited, provide the full question wording or estimate the number of filings affected. The results should be read as a survey of judges’ reported experiences, not a court-wide audit.
Limits of the Survey Evidence
The results do not establish how many court filings contain false citations, how often AI was involved, or whether errors were intentional. The administration did not report how many judges were invited or publish the full wording of the questions in the material described by the source. Because judges reported what they had encountered, the figures may not represent all courts or filings.
A translation issue also affects one widely circulated account. Yonhap’s English version, republished by The Korea Herald, said 164 judges had themselves cited false precedents. The Korean original, as described in the source, says those judges identified the parties themselves as a source. The survey does not say that 164 judges admitted submitting false citations.
The administration’s proposed measures remain plans, not enacted rules. The available material does not specify the wording, scope or enforcement process for any future fines, citation-checking duty or AI-use disclosure requirement.
Proposed Changes to Procedure Laws
The National Court Administration says it plans to propose changes to South Korea’s Civil and Criminal Procedure Acts that would provide a legal basis for fines related to false citations. The survey also records support for requiring parties or representatives to verify cited authorities and disclose AI use. The administration has not, in the source material, set out a final draft or timetable.
The next steps are whether the proposals are formally submitted, how lawmakers define covered conduct, and what safeguards would apply before a penalty is imposed. Until those details are available, the survey documents judges’ reported experiences and preferences, while the scope of any new rules remains undecided.
Key Questions
What did South Korea’s judges report?
About 80% of responding civil, family and administrative judges said they had encountered false or nonexistent precedent citations. The survey recorded judges’ experiences, not the share of all court filings containing false citations.
Did the survey show that all false citations came from AI?
No. The court administration connected its concern to AI-generated hallucinations and described examples involving AI, but the results do not establish that every reported false citation was AI-generated.
Did 164 judges admit citing fake precedents?
No. According to the Korean-language release as described in the source, 164 judges named the parties themselves as a source of false material. An English-language account mistranslated that finding as judges citing false precedents themselves.
What changes are being considered?
The National Court Administration says it plans to propose procedural-law changes that could allow fines. Survey respondents also supported a duty to verify citations and a requirement to disclose AI use, but the rules have not been enacted.
