TL;DR
South Korea’s National Court Administration published a survey on November 2, 2026, in which 360 judges reported encountering fabricated or distorted legal citations. The survey measures judges’ experiences, not the prevalence of fake citations in court filings, and the administration says it plans to propose procedural-law changes that could allow fines.
South Korea’s National Court Administration reported on November 2 that judges in civil, family and administrative courts have encountered fabricated or distorted legal citations, including nonexistent precedents and real rulings described inaccurately. The administration’s first survey on the issue drew responses from 360 judges and has prompted calls for citation-checking duties and possible fines, though it does not establish how often fake citations appear in filings overall.
The survey was conducted from October 6 to 16, 2026, among judges at courts at all levels, according to a four-page release from the National Court Administration, the Supreme Court’s administrative arm. The administration said false citations can place an unnecessary verification burden on opposing parties and interfere with the speedy conduct of trials. It did not disclose how many judges were invited or provide the exact wording of the survey questions.
Among the civil, family and administrative judges covered by the headline finding, about 80% said they had encountered cases involving false or nonexistent precedents. The most common reported types were precedents that did not exist, identified by 196 judges, and real precedents cited with false content, identified by 159. These figures are responses to a multiple-choice question, not counts of individual filings.
The denominator matters: the 80% figure is not the share of all survey respondents. The Korean daily Kyunghyang Shinmun reported that 243 of all 360 respondents had encountered fake citations, or 67.5%. The court release’s wording and the reported figures indicate that the higher rate applies to the specified civil, family and administrative judges. The survey measures what judges said they had seen, not the rate of false citations across the court system.
Why Citation Accuracy Matters in Court
False legal references can require judges and opposing parties to spend time checking whether a case exists and whether it supports the argument being made. The court administration said this verification burden can slow proceedings. A fabricated precedent may also make a party’s legal position appear supported by authority that does not exist; a distorted account of a real ruling can misstate what a court decided.
The reported sources include both litigants representing themselves and licensed lawyers. In the survey, 164 judges (69.5%) identified parties themselves as a source of false material, while 136 (57.6%) identified lawyers acting as representatives or defense counsel. Those percentages refer to answers to the source question, which allowed multiple selections; they do not show that the two groups submitted separate or mutually exclusive sets of filings.
The findings also underscore the need to check translations and source documents when reporting on the issue. An English-language version of a Yonhap report republished by The Korea Herald said 164 judges had cited false precedents themselves. The Korean release instead says those judges identified the litigants themselves as the source. The distinction is material, and the original-language document does not support the claim that judges admitted submitting fake citations.

What the Court Survey Describes
The National Court Administration said the survey was prompted by concerns that AI systems can generate false or nonexistent precedents. Its release describes examples of filings containing invented judgments formatted to resemble Supreme Court decisions, Supreme Court case numbers attached to reasoning that could not be located, and real rulings whose holdings were changed or misrepresented.
The release also describes material that appears to have been copied from AI conversations, including chatbot-style language and notes about litigation strategy. These are examples reported by the court administration; the survey does not quantify how many filings contained each type or determine that AI was used in every instance. The administration’s stated concern is the appearance of false citations, including those associated with AI-generated errors.
Judges called for institutional action: 91.7% of respondents said a response was needed, and 64.8% described one as very necessary. In the measures listed in the release, the most selected options were a legal basis for fines, a duty to verify cited precedents, and a duty to disclose AI use. Respondents could select more than one measure.
What the Survey Cannot Establish
The survey does not say how common fake citations are across all court filings. It records judges’ reported experiences, and the administration did not publish the number of judges invited, the response rate, or the full wording of its questions. The results therefore cannot establish the proportion of filings affected or whether the reported cases have increased over time.
The release also does not attribute every false citation to AI. It discusses AI-generated errors as a concern and describes examples of chatbot material in filings, but the information provided does not show how each cited error was produced or whether it was deliberate. The reported figures are judges’ selections in a survey, not findings from a case-by-case audit.
Nor does the survey establish what legal consequences currently apply in every circumstance. It records judges’ preferences for possible institutional measures. The administration has said it plans to propose changes to procedure laws, but the release does not provide a final bill, a timetable for legislative action, or details of how any fine or disclosure rule would work.
Proposed Changes to Procedure Laws
The National Court Administration says it plans to propose amendments to South Korea’s Civil and Criminal Procedure Acts to provide a legal basis for fines related to false citations. The survey’s other leading proposals include requiring parties or lawyers to verify cited precedents and to disclose AI use. These are proposed responses, not rules shown by the survey to have been enacted.
The next concrete step is whether the administration presents draft amendments and how lawmakers and courts respond. Until further details are published, the scope of any new duties, the standard for imposing a fine, and how AI-use disclosure would be applied remain unsettled. The court administration’s published results provide a first account of judges’ reported experiences, but do not resolve those policy questions or establish the scale of the problem across filings.
Key Questions
What did South Korea’s court survey find?
The National Court Administration said about 80% of responding civil, family and administrative judges had encountered cases involving false or nonexistent precedents. The survey included 360 judges across court levels and ran from October 6 to 16, 2026.
Does the 80% figure refer to all 360 judges?
No. It refers to responding judges handling civil, family and administrative cases. Kyunghyang Shinmun reported that 243 of all 360 respondents—67.5%—said they had encountered fake citations.
Did the survey prove that AI created every false citation?
No. The administration raised concerns about AI-generated errors and described examples including chatbot material in filings, but the survey does not identify the source of every false citation or establish how many were produced using AI.
What rules are being considered?
The administration says it plans to propose changes to civil and criminal procedure laws that could allow fines. Judges also favored a duty to verify cited precedents and a duty to disclose AI use. These measures are proposals, not confirmed enacted requirements.
