Corporate Investigations & White Collar Defense

"Internationally recognised as a leading white-collar criminal defence team comprising former judges and police investigators,
ably supported by in-house forensic expertise."
– Chambers Asia Pacific 2019


Kim & Chang’s Corporate Investigations & White Collar Defense Practice is comprised of attorneys and professionals with market-leading expertise and industry experience.  Kim & Chang’s attorneys regularly represent clients in complex and sophisticated anti-corruption, financial crimes, antitrust, tax evasion, trade secrets, privacy law violations and general compliance matters.  

We see an increasing number of domestic criminal cases developing into multi-jurisdictional investigations involving antitrust, trade sanctions, or the US Foreign Corrupt Practices Act (“FCPA”) and the UK Bribery Act.  With the requisite manpower, capabilities, and know-how, we navigate through the complex legal framework of many different jurisdictions and coordinate efficiently among various practices within the firm.

Key Servicesshow


Ethical standards are being reinforced at an ever-growing rate in both public and private sectors in Korea and in other OECD countries, including the US.  Part of this trend is the increasing enforcement of the laws of one jurisdiction in another, such as the FCPA and the UK Bribery Act.  


Korea also has a wide array of anti-corruption laws, including the Criminal Code, the Act on the Aggravated Punishment, Etc. of Specific Crimes, the Act on Prevention of Improper Solicitation and Provision/Receipt of Money and Valuables (the “Improper Solicitation and Graft Act”) and the Act on Combating Bribery of Foreign Officials in International Business. Our Corporate Investigations & White Collar Defense Practice has observed increased interests in general compliance issues throughout Korean society since the Improper Solicitation and Graft Act took effect on September 28, 2016, especially because the new law imposes corporate liability for violations of the anti-corruption provisions.  


We have undertaken effective defense efforts for a diverse group of clients involved in domestic corruption cases, and advocated for anti-corruption at a global level.  We also regularly advise our clients in developing strong monitoring and control systems, and in conducting internal audits.

Finance/Insurance/Securities Sector Experience 

With the increased sophistication and globalization in capital markets, a robust defense strategy requires up-to-date professional knowledge of the industry and complete understanding of the highly regulated financial markets.  Our Corporate Investigations & White Collar Defense Practice has successfully represented numerous financial institutions and their officers and directors in connection with various high-profile cases.  

Tax/Customs/Foreign Exchange

In recent years, there has been a greater propensity of seemingly routine tax, customs and other regulatory audits involving a referral to the police and prosecutors for a criminal investigation. 


As a result, a seemingly routine regulatory inquiry may involve not only the relevant regulatory authorities, such as the relevant tax office, customs office, the Financial Supervisory Commission, or the Bank of Korea, but also the police and prosecutors.  Familiarity with the types of procedures conducted by these organizations is an essential part of a successful defense effort.  Over the course of several decades, Kim & Chang has accumulated unique know-how, providing highly sophisticated legal services to our clients.  Together with former government officials from regulatory agencies, Kim & Chang offers the insight and most appropriate solution to any given complex regulatory case.

Fair Trade/Antitrust

In Korea, the government has been calling for stricter standards and increased penalties in the enforcement of rules against unfair trade practices and other antitrust-related cases. The Korea Fair Trade Commission has increased its level of activities, and a growing number of cases are being referred to the Prosecutors’ Office for criminal prosecution. 
The Prosecutors’ Office has also focused on competition law issues, as evidenced by the establishment of a department that is exclusively responsible for antitrust cases. 


Our team of lawyers, in close cooperation with colleagues from the Antitrust & Competition Practice, has provided proactive defense activities at all relevant stages and guidance on preemptive measures. 

Trade Secrets/Intellectual Property

Trade secret infringement cases have evolved from traditional disputes among competitors into more complex, cross-border disputes involving suppliers or vendors.  As such, the ability to engage in highly technological discussions has become a key requirement in understanding and resolving these matters.  Our Corporate Investigations & White Collar Defense Practice collaborates with our firm’s patent specialists to provide comprehensive and systematic defense activities from the initial investigation stage to the trial stage.

Construction/Real Estate

Criminal cases have arisen from construction cases ranging from large-scale renovations involving bid-rigging to various cases involving technical industry regulations.  Our Corporate Investigations & White Collar Defense Practice has successfully conducted defense activities, and is a pioneer in this area, successfully representing clients in landmark cases, together with our firm’s litigation specialists.

Medical/Pharmaceutical Industry

With growing national interest in health-related industries, and the introduction of a more rigid regulatory regime, including the so-called “Dual Punishment System,” Korean regulatory authorities are increasingly monitoring and fighting what had once been a pervasive social practice – the giving and taking of rebates.  


Our Corporate Investigations & White Collar Defense Practice works closely with the medical and pharmaceutical experts in our Health Practice to appropriately address and respond to these dramatic changes in the industry.  


For more than 40 years, our Health Practice has advised the great majority of multinational firms in these sectors, from established industry leaders to newer biotech companies and start-ups. 

Environment/Plant Safety/Product Liability 

Environmental issues have become a primary focus of social concern in Korea.  Safety concerns over consumer products and observation of emission standards and other safety issues in automobiles have drawn keen interest. 


We have represented and provided strategic advice to various clients in large-scale environmental issues drawing national attention. 

Labor & Employment

With the emergence of growing income inequality as an overarching social issue in Korea, the Korean government has introduced stricter standards to regulate labor-related issues, such as non-regular employees and illegally dispatched employees.  


Further, labor unions frequently request the Prosecutors’ Office to conduct criminal investigations of labor-related issues, including the use of the threat of an investigation as leverage in labor negotiations with employers.  In these types of criminal investigations, defense becomes particularly critical as individual senior executives of companies can be criminally charged.


Our Corporate Investigations & White Collar Defense Practice has provided successful defense activities with the support of certified labor consultants for companies faced with complex labor-related issues.

Audits/Internal Investigations

With rising expectations of transparency in Korean corporate activities, preemptive and remedial measures (including internal investigations) are being called for to deal with non-compliant elements of the corporate environment.  


In recent years, the Korean government has encouraged whistleblowing by enacting laws to protect whistleblowers.  The increase in whistleblowing has underlined the importance of dealing with them proactively.  


Our Corporate Investigations & White Collar Defense Practice has extensive experience in conducting internal investigations for corporate management, boards of directors, regional management, and global management.  


In addition to major, high-profile investigations that would ultimately involve interactions with government agencies, we also specialize in more focused, rapid, and confidential reviews.  We understand the need to minimize the disruption to business operations and potential collateral consequences to our clients. 


Our Corporate Investigations & White Collar Defense Practice also includes an unparalleled team of experienced forensics experts.  Our pool of resources enables us to engage in internal audits and investigations across a wide range of issues.  Our team includes specialists in both forensic accounting and digital forensics.  


Our firm began employing digital forensics experts more than a decade ago, and remains the only law firm in Korea with a significant pool of IT engineers with investigation experience.  They provide meaningful contributions in our investigation, compliance, and criminal defense matters.  


Our forensics team works closely with our compliance and anti-corruption experts to provide our clients a total package of services.  In addition, based on our significant whistleblowing case experience, our Corporate Investigations & White Collar Defense Practice provides companies with strategic and practical legal and non-legal advisory services.

Privacy Laws

The Personal Information Protection Act (“PIPA”) was enacted in 2011.  In addition, other privacy laws in Korea impose an extensive array of protective measures to safeguard personal information, which companies doing business in Korea may collect and use in the course of their business.  As a result, companies are facing new types of risks arising from PIPA violations. 


In close coordination with our Privacy & Data Security Practice experts, our practitioners have defended most of the landmark cases in this area, and provide wide-ranging and in-depth service to our clients.
