TL;DR
South Korea’s National Court Administration published its first survey on false legal citations on November 2, 2026. About 80% of responding civil, family and administrative judges said they had encountered fake or distorted precedents; the figure was 67.5% across all 360 judges, according to Kyunghyang Shinmun. The administration plans to propose procedural law changes that would allow fines, but the survey does not measure how often false citations appear in court filings.
South Korea’s National Court Administration said a survey of 360 judges found that about 80% of respondents handling civil, family and administrative cases had encountered false or nonexistent precedents in court submissions, prompting plans to propose procedural law changes that would permit fines. The findings, published November 2, 2026, document judges’ reported experiences, not the share of court filings containing fabricated citations.
The survey was conducted between October 6 and 16 among judges at courts of all levels. Among the judges asked about the types of false citations they had seen, 196 (80.7%) identified 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 figures use respondents to the relevant question as their denominator.
The widely repeated “eight in ten” figure applies to responding judges in civil, family and administrative matters. Across all 360 survey participants, 243 judges, or 67.5%, reported encountering fake citations, Kyunghyang Shinmun reported. The court administration’s release does not itself give that all-respondent figure. It also recorded reports of false or nonexistent statutes and legal literature, though less frequently.
Judges identified both litigants and legal representatives as sources. 164 judges (69.5%) said parties themselves had submitted false material, and 136 (57.6%) said it had appeared in documents submitted by lawyers. The administration’s release says such citations were found not only in filings by parties but also in many documents submitted by lawyers. These are judges’ reports, not an independently verified count of individual filings or practitioners.
Pressure for New Court Safeguards
The findings point to a verification burden inside the courts: judges and opposing parties may need to spend time checking whether a cited ruling exists and whether it supports the argument made. The National Court Administration said false citations can burden opposing parties and hinder the speedy progress of trials.
Most respondents favored an institutional response: 91.7% said one was needed, and 64.8% described it as very necessary. The most frequently selected proposals 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%). Because respondents could choose multiple measures, those percentages are not competing, exclusive options.
The issue reaches beyond the use of AI itself. A fabricated reference can appear authoritative while referring to no real decision; a real ruling can also be misrepresented. Rules that put more responsibility on those filing documents could affect lawyers and self-represented litigants alike. The survey records judges’ views, however, and does not establish the scale of harm to particular cases.

What the Survey Actually Measured
The National Court Administration, the administrative arm of South Korea’s Supreme Court, released the results in a four-page statement titled “Results of the survey on citations of AI-generated false precedents and similar material.” The questions addressed judges’ experiences and their preferred responses. The administration said AI hallucinations can produce citations to nonexistent rulings, but the survey does not establish that AI was responsible for every false citation reported.
The release described examples including AI-generated fake judgments formatted to resemble Supreme Court decisions, case numbers that lead to no searchable ruling, and real holdings altered or presented contrary to their meaning. It also cited filings containing text from AI conversations or litigation-strategy wording left in place. Those examples illustrate different kinds of errors; they do not provide a count of how often each occurs.
Care is needed when reading translated accounts. An English report by Yonhap, republished by The Korea Herald, said 164 judges had cited false precedents themselves. The source’s Korean wording instead says those judges identified the parties themselves as the submitters. The discrepancy is a translation error, not an admission by judges.
Limits of the Judges’ Reports
The court administration has not disclosed how many judges were invited, the full wording of the survey questions or a filing-level count of false citations. The results measure what participating judges said they had encountered, so they cannot show the prevalence of fabricated material across all South Korean court documents.
The survey also does not establish which false citations were generated by AI, whether they affected case outcomes, or how often lawyers knowingly submitted inaccurate material. The reported source categories may overlap because judges could select more than one answer. The proposed fines, verification duty and AI-use disclosure are survey preferences, not rules already in force.
Proposed Changes to Procedure Laws
The National Court Administration plans to propose amendments to South Korea’s Civil and Criminal Procedure Acts to create a legal basis for fines related to false citations. The survey release does not set out a timetable, draft wording or the conditions under which penalties would apply.
Any proposal would need to move through the legislative process before becoming law. Until more details emerge, it remains unclear whether the administration will pursue all three leading measures—fines, a citation-verification duty and disclosure of AI use—or how the rules would distinguish deliberate fabrication from an error. The next concrete development will be publication or submission of a formal legislative proposal.
Key Questions
What did South Korea’s judges report?
In a survey published November 2, 2026, about 80% of responding judges handling civil, family and administrative cases said they had encountered false or nonexistent precedents. The survey included 360 judges overall.
Does the survey show that 80% of court filings contain fake citations?
No. The figure describes judges’ reported experience, not the proportion of filings containing false citations. The survey did not provide a filing-level prevalence estimate.
Were lawyers identified as a source?
Yes. 136 judges (57.6%) said lawyers acting as representatives or defense counsel had submitted false material. Judges could select multiple source categories, and the result is not a count of individual lawyers.
What changes are being considered?
The National Court Administration plans to propose changes to the Civil and Criminal Procedure Acts that would allow fines. Survey respondents also favored duties to verify citations and disclose AI use, but those measures are not yet established law.
