Insurance Complaints Surge as AI Lowers the Barrier to Filing
A man in his 50s from Busan filed 18 identical insurance complaints over two weeks, using generative AI to slightly alter the wording each time. After an insurer denied his claim for treatment beyond the initially diagnosed four-week period, he turned to AI to circumvent the rejection. The Financial Supervisory Service received all 18 filings.
Insurance complaints across South Korea jumped 19.3% in the first quarter of 2026 compared to the same period last year, reaching 15,996 cases. This marks the largest quarterly increase since the Korea General Insurance Association and Korea Life Insurance Association began tracking data in 2016.
Demographic Pressure Meets Aging Infrastructure
Property insurers handled 11,108 complaints in the first quarter, while life insurers processed 4,888. For property insurers-which sell high-complaint products like medical expense and auto insurance-quarterly complaints have climbed steadily from around 9,000 a decade ago to over 11,000 today.
The second baby boom generation, born between 1964 and 1974, has entered their 50s and 60s. This large population cohort is filing more medical claims and, when denied, concentrating their complaints. A complaint handler at a domestic property insurer said, "Recently, those in their 50s and 60s who receive medical treatment often file concentrated complaints if their claims are denied. Post-retirement, health management has become more critical, and conflicts over non-covered items like physical therapy persist."
Claims for daily life liability insurance-which covers damage from leaks in aging apartments and villas-are also rising. A 40-year-old office worker in Seoul filed a complaint after receiving a lower payout than expected for a leak claim. Financial authorities expect complaints to increase steadily over the next 5 to 10 years as both people and buildings age.
AI Removes Friction from the Filing Process
Generative AI has drastically simplified complaint preparation. Filing typically requires reviewing complex regulations and precedents, but generative AI now produces plausible complaint documents with minimal effort.
A 40-year-old office worker described his experience: his wife was diagnosed with cancer and sought a 10 million Korean won payout, but the insurer invalidated the contract due to unpaid premiums. He used AI to file a complaint without the burden of navigating the complex process himself.
Insurers report that AI-generated complaints now arrive with opening lines like "That's a great question," making them instantly recognizable. Many cite false precedents or outdated regulations, forcing complaint handlers to spend significant time verifying claims.
Malicious Filing Creates Operational Strain
Some complainants file 2 to 3 documents daily and make 100 calls to insurers, pushing legitimate grievances aside. An industry insider said, "We need countermeasures." Several insurers have reportedly received proposals from AI detection service providers used for academic plagiarism checks to develop solutions for identifying AI-generated complaints.
The surge reflects a genuine tension: while consumers benefit from easier access to complaint processes for complex regulatory disputes, the volume of malicious filings now threatens to overwhelm legitimate claims. Insurers face pressure to distinguish between valid grievances and coordinated abuse of the system.
