TL;DR
South Korea’s National Court Administration published a survey of 360 judges on false or distorted citations in court filings. About 80% of responding judges handling civil, family and administrative cases said they had encountered them; the survey records judges’ observations, not the prevalence of fake citations across all filings. Judges called for institutional measures, including possible fines and duties to check citations and disclose AI use.
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 precedents in court filings. The findings are based on answers from 360 judges and have prompted calls for rules addressing fabricated citations and the use of AI-generated material.
Among judges who reported encountering false citations, 196 (80.7%) said they had seen precedents that did not exist, while 159 (65.4%) said they had seen real precedents cited with false content. Respondents could select more than one type. The survey also recorded reports of false or nonexistent statutes and legal publications, though less frequently.
The “about 80%” figure has a limited denominator: it refers to responding judges handling civil, family and administrative cases. The source release does not state that 80% of all 360 respondents had encountered fake citations. South Korean newspaper Kyunghyang Shinmun reported that 243 of the 360 judges (67.5%) had experienced them. The administration’s survey measures what judges said they had encountered, not the share of filings containing false material.
Judges identified both self-represented litigants and licensed lawyers as sources. 164 judges (69.5%) named the parties themselves, and 136 (57.6%) named lawyers acting as representatives or defence counsel. The administration said false citations appeared in documents submitted by both groups. These figures do not establish how often each group submits inaccurate citations across cases.
Judges Seek Rules for Citation Checks
The survey matters because fabricated legal authorities can take time to detect and may complicate proceedings. The court administration said false citations place an unnecessary verification burden on opposing parties and can hinder the speedy progress of trials. A citation that looks formally credible but cannot be found may require lawyers and judges to check case records before they can assess the argument.
91.7% of respondents supported an institutional response, according to the results. The most selected measures included a legal basis for fines, a duty to verify cited precedents and a duty to disclose AI use. These are survey responses, not rules already in force. If the proposed procedural changes advance, they could affect how litigants and lawyers prepare and support claims in South Korean courts.
The findings also point to a practical distinction: AI tools may produce text that resembles a judgment without accurately representing an actual ruling. But the survey does not attribute every false citation to AI, and its results do not quantify the scale of the problem across court filings.

How the Court Collected Responses
The National Court Administration, the administrative arm of South Korea’s Supreme Court, asked judges at courts of all levels about citations of AI-generated false precedents and similar material. The survey ran from October 6 to 16, 2026, and the administration published the results on November 2. It described the poll as its first survey on fake citations in filings.
The administration’s release gave examples of the material judges had encountered: judgments generated in the format of Supreme Court decisions; case numbers attached to reasoning that could not be matched to a real ruling; real decisions quoted in altered form or against their actual meaning; and chatbot dialogue or litigation-strategy notes left in submitted documents. These examples describe reported cases, not a finding that all such material was AI-generated.
The source release does not give the number of judges invited, the response rate or the full wording of the questions. Percentages in its tables are based on respondents to the relevant questions, and some questions allowed multiple answers. Those limits matter when comparing the reported shares or drawing conclusions about the judiciary as a whole.
Survey Limits and Open Questions
The survey does not show how many filings contain fake citations, how often judges encounter them over a defined period or how representative the 360 respondents are. The administration did not publish the number invited or a response rate in the material provided. Its results rely on judges’ reported experience and cannot establish whether the problem is increasing.
The source material also does not establish what share of false citations were produced by AI, as opposed to other errors or deliberate fabrication. Nor does it say whether judges verified every reported example or provide case-level details that would allow independent review. The proposed measures have not been described here as enacted law.
A separate translation discrepancy illustrates the need to check the underlying record. Yonhap’s English version, republished by The Korea Herald, said 164 judges had cited false precedents themselves. The Korean source says those judges identified the litigants themselves as a source. The survey does not report that judges admitted to filing false citations.
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, according to the source material. Judges also expressed support for citation-verification duties and disclosure of AI use, but the material does not establish that those proposals will be included in legislation or specify their final wording.
The next concrete step is whether the administration submits proposals and how lawmakers or the courts respond. Until draft language, a timetable or formal decisions are available, the scope of any new penalties or duties remains unknown. The survey itself does not change existing requirements for court filings.
Key Questions
What did the survey find?
The National Court Administration reported that about 80% of responding civil, family and administrative judges had encountered false or nonexistent precedents. The finding is based on judges’ reports, not a count of all filings.
Did 80% of all 360 judges report fake citations?
No. The 80% figure applies to judges handling civil, family and administrative cases. Kyunghyang Shinmun reported that 243 of all 360 respondents, or 67.5%, had encountered fake citations.
Were lawyers named as a source?
Yes. 136 judges (57.6%) named lawyers acting as representatives or defence counsel, while 164 named the parties themselves. Respondents could select more than one source.
Are fines or AI-disclosure duties already in force?
The survey records judges’ preferences, not enacted rules. The administration plans to propose procedural-law changes that would allow fines; the status and wording of any wider requirements remain unclear.
Does the survey prove AI caused the false citations?
No. The release discusses AI-generated false precedents and gives examples, but the survey results do not establish what share of reported citations came from AI.
