Elevator Defect Dispute Support


Disputes involving elevators are often intertwined with complex engineering mechanisms and legal liability issues related to buildings, 
making it extremely difficult to determine responsibility through conventional defect handling procedures. 


Backed by the advanced expertise of certified construction appraisers, court-appointed expert appraisers, and former members of the Ministry of the Interior and Safety's Accident Investigation & Determination Committee
GLS provides comprehensive technical and legal analysis and expert appraisal of the key issues involved in legal disputes.


Rather than relying on assumptions, we support clients with expert appraisal reports based on engineering evidence and objective data to help achieve fair and reasonable outcomes in court litigation and 
arbitration proceedings before the Korean Commercial Arbitration Board (KCAB).
