Expert Witness Services
Expert Services International can provide expert witness services in South Korea, particularly in international arbitration under KCAB rules and cross-border construction disputes.
Korean Expert Witness Practice
Expert Services International can provide expert witness services in South Korea, particularly in international arbitration and cross-border construction disputes. South Korea operates a civil law system, and expert evidence in domestic courts is primarily provided through court-appointed experts (gamdeongin) under the Civil Procedure Act.
The Korean Arbitration Act (amended 2016) implements the UNCITRAL Model Law. The Korean Commercial Arbitration Board (KCAB) is the principal arbitration institution, and the Framework Act on the Construction Industry governs construction disputes. In international arbitration, party-appointed experts are accommodated under KCAB International Arbitration Rules and other institutional rules.
South Korea is a civil law jurisdiction. Expert evidence in domestic courts is primarily provided through court-appointed experts (gamdeongin) under the Civil Procedure Act. Party-appointed experts are accommodated in international arbitration under institutional rules.
Expert Evidence Framework
The South Korean civil litigation system, grounded in civil law traditions, has established distinctive procedures for expert evidence that differ significantly from common law jurisdictions. The Civil Procedure Act of South Korea, particularly Articles 349 through 359, establishes the framework for expert evidence in civil proceedings. The system is based on court-appointed experts rather than the party-appointed expert evidence model prevalent in common law jurisdictions such as Australia or the United Kingdom.
Court-appointed experts in Korean proceedings are selected through a formal process conducted by the court. The court may appoint experts upon the request of either party or on the court's own initiative, and the selection process typically involves consultation with expert associations or specialist bodies. Once appointed, court experts must satisfy stringent requirements of impartiality and independence, with complete separation from the interests of either party. The court sets detailed instructions regarding the matters on which expert analysis is required, the methodology to be employed and the timeframe for provision of the expert opinion. Court-appointed experts in Korean proceedings are bound by a fundamental duty of objectivity and must acknowledge their overriding duty to assist the court in establishing the facts and technical issues relevant to the dispute.
The opinions of court-appointed experts are treated with considerable deference by the courts. Unlike party-appointed evidence, which the court must evaluate with cautious regard to potential bias or partisanship, court-appointed expert opinions are accorded substantial weight by the judicial system. This reflects the underlying civil law philosophy that the court, rather than the parties, should direct the process of fact-finding and expert analysis. Party-appointed reports, when permitted, are typically treated as documentary evidence rather than as expert testimony in the Anglo-American sense, and carry significantly less weight than court-appointed expert opinions. The court may examine court-appointed experts, typically through questions posed by the judge, and in some instances the parties may be permitted to pose questions to the expert or to present comments on the expert's analysis. This procedure differs markedly from the common law cross-examination model, instead reflecting civil law traditions of judicial inquisition and inquiry.
Expert analysis in Korean court proceedings may be presented in writing or orally, depending on the court's directions. Where oral evidence is required, the court examines the expert directly, and the parties may have the opportunity to pose questions or to challenge the expert's analysis. The court may appoint an appraiser (expert assessor) upon the request of either party, and the appraiser's role is to provide specialist analysis of specific factual or technical matters. This distinctive procedural framework requires expert witnesses operating in Korean courts to understand and respect the court-centred nature of the system, the emphasis on impartiality and independence, and the deference accorded to court-appointed expertise.
International Arbitration
Arbitration has become an increasingly important mechanism for the resolution of international and domestic construction and infrastructure disputes in South Korea. The South Korean Arbitration Act establishes the legal framework governing both domestic and international commercial arbitration. Within this framework, the Korean Commercial Arbitration Board has emerged as the principal institution for conducting arbitrations in Korea, offering both domestic and international arbitration services.
The KCAB Domestic Arbitration Rules, which became effective on 1 March 2025, establish the procedural framework for domestic arbitration conducted under KCAB administration. These rules provide guidance on the conduct of hearings, the presentation of evidence, the appointment of arbitrators and the resolution of procedural matters. For international commercial arbitration, the KCAB International Arbitration Rules represent the principal framework governing international cases. A significant development occurred with the promulgation of the KCAB International Arbitration Rules 2026, which became effective on 1 January 2026. These updated rules represent the most comprehensive revision of the KCAB International Rules in over a decade and incorporate significant contemporary developments in international arbitration practice.
The KCAB International Arbitration Rules 2026 include important provisions addressing twenty-first century developments in international dispute resolution. The rules now require comprehensive disclosure of any third-party funding arrangements, reflecting international developments in the regulation of litigation and arbitration funding. The rules also incorporate detailed provisions addressing the use of artificial intelligence and the disclosure of any artificial intelligence tools or processes employed in the preparation of submissions, evidence or legal arguments. These provisions reflect the growing international concern about ensuring the authenticity and human authorship of materials submitted in arbitration. The 2026 Rules also contain refined provisions governing the consolidation and joinder of multiple proceedings, allowing for more flexible and efficient management of complex multi-party disputes. These developments demonstrate the KCAB's commitment to ensuring that Korean arbitration practice remains aligned with best practice in major international arbitration centres.
The Korean Commercial Arbitration Board currently administers approximately four hundred arbitral proceedings annually. The majority of these cases involve construction and infrastructure disputes, information technology and commercial disputes. This substantial caseload reflects Korea's position as a major commercial and construction centre and the growing adoption of arbitration by Korean and international businesses. The Korean government has demonstrated strong commitment to the development of Seoul as a major international arbitration seat. In December 2024, the Ministry of Justice released the "Master Plan for Promotion of Arbitration Industry 2024-2028," a comprehensive strategy to develop Korea's arbitration infrastructure, promote the adoption of arbitration in construction and commercial disputes, and position Seoul as a leading arbitration centre within Asia-Pacific. This Master Plan includes measures to promote legislative developments, to establish specialised training programmes for arbitrators and counsel, and to develop the physical and digital infrastructure supporting arbitration practice in Korea.
In January 2025, the South Korean Supreme Court reaffirmed its pro-arbitration policy in formal pronouncements supporting the role of arbitration in the Korean dispute resolution system and committing to a policy of minimal court intervention in arbitral proceedings except in cases of fundamental procedural irregularity. This judicial endorsement reflects a broader move towards embracing arbitration as a primary mechanism for the resolution of commercial disputes in Korea, consistent with international best practice and the role of arbitration in other major international commercial centres.
Expert evidence procedures in Korean arbitration are governed primarily by the applicable KCAB rules and the agreement of the parties. The IBA Rules on Taking of Evidence in International Arbitration are frequently adopted or referenced as a framework for the conduct of expert evidence in international arbitrations seated in Korea. The Chartered Institute of Arbitrators Protocol for the Use of Party-Appointed Expert Witnesses in International Arbitration provides a detailed framework for party-appointed expert evidence that is increasingly recognised in Korean arbitration practice. These international frameworks provide practical procedures for the conduct of expert evidence in Korean arbitration, allowing for the presentation of party-appointed expert evidence, concurrent expert procedures, expert meetings and court-appointed or tribunal-appointed expert evidence as appropriate to the particular dispute.
Construction Disputes
The Framework Act on Construction Industry of South Korea establishes a comprehensive legislative framework governing the construction sector, including mechanisms for the resolution of disputes arising from construction contracts and construction operations. This Act reflects Korea's commitment to providing effective dispute resolution mechanisms that address the distinctive features of construction industry disputes, including their technical complexity, the involvement of multiple parties and stakeholders, and the time-sensitive nature of construction operations.
An important feature of the Korean construction dispute resolution framework is the Construction Dispute Mediation Committee, established under the Framework Act on Construction Industry. The Construction Dispute Mediation Committee provides an optional pre-litigation mediation mechanism for parties to a construction dispute to attempt to resolve their differences before resorting to litigation or arbitration. This mediation process is administered by specialist bodies with expertise in construction matters, and the mediators bring knowledge of construction industry practice, contractual norms and technical requirements relevant to construction operations. The availability of construction-specific mediation provides an efficient mechanism for resolving disputes without the formality and expense of litigation or arbitration, and many construction disputes are resolved through this mechanism without the need for court proceedings.
The Building Act of South Korea establishes the Architectural Dispute Mediation Committee, which provides specialist mediation services for disputes relating to building design, architectural services and building-related matters. This committee similarly provides pre-litigation mediation services for architectural and building-related disputes, allowing parties to resolve issues through a mediation process administered by specialists in the building and architectural sectors.
International construction projects executed in Korea, or involving Korean contractors and participants, frequently incorporate standard form contracts reflecting international practice. The Fédération Internationale des Ingénieurs-Conseils standard forms are widely utilised in major international construction projects in Korea, and many international contracts incorporate provisions for expert determination and dispute boards as mechanisms for the timely resolution of technical issues. These international contractual frameworks often provide for expert evidence procedures that follow international best practice, creating opportunities for experts experienced in both Korean law and international construction standards to serve effectively in complex international disputes.
Contemporary Issues
South Korean dispute resolution practice is experiencing significant contemporary developments that reflect both the increasing internationalisation of Korean commerce and the adoption of contemporary best practices from international dispute resolution centres. The KCAB International Arbitration Rules 2026 represent the most comprehensive revision of Korean international arbitration procedures in more than a decade, and the updated rules incorporate significant provisions addressing developments that have emerged as major concerns in international arbitration during the past ten years.
The promulgation of the KCAB International Arbitration Rules 2026 marks a significant step forward for Korean arbitration practice. The new rules incorporate requirements for the disclosure of third-party funding arrangements, reflecting the evolution of international dispute resolution funding and the need for transparency regarding financial arrangements that might affect the conduct or interests of parties in arbitration. The rules also establish detailed provisions governing the disclosure of artificial intelligence tools and processes, requiring the identification of any artificial intelligence resources employed in the preparation of submissions, evidence or legal arguments. These provisions reflect growing international recognition that the use of generative artificial intelligence in the preparation of legal and evidentiary materials requires transparency and human oversight to ensure that the materials reflect genuine human authorship and expertise.
The Korean government's "Master Plan for Promotion of Arbitration Industry 2024-2028," released by the Ministry of Justice in December 2024, demonstrates the commitment of Korean policymakers to the development of Seoul as a major international arbitration seat. This strategic plan includes initiatives to modernise the legislative framework for arbitration, to develop professional training programmes for arbitrators and counsel, and to enhance the physical and digital infrastructure supporting arbitration in Korea. The plan reflects recognition that arbitration is increasingly important to Korea's commercial and construction sectors and that Seoul's development as an arbitration centre contributes significantly to Korea's position in the global business and investment community.
These developments in Korean expert witness and arbitration practice demonstrate the dynamism of the Korean dispute resolution system and the commitment of Korean courts, institutions and government to ensuring that Korean dispute resolution practice remains responsive to contemporary developments and aligned with best practice in other major international centres. Expert witnesses operating in Korean disputes must maintain awareness of these continuing developments and adapt their practice to reflect the evolving requirements of both Korean courts and Korean arbitration proceedings.
