International arbitration Tier 2

KL Partners has gained significant traction in the domestic and international legal market since it was established in 2015, when experienced arbitration partners Beomsu Kim and Eun Nyung (Ian) Lee left Shin & Kim to set up a new firm. In addition to serving existing clients that have turned to the firm for advice since its inception, the team has also recently won mandates from a significant number of new clients. With all of the aforementioned founding partners having a corporate law background, the firm has become a first port of call for high-profile post-M&A arbitration cases; one recent example involved the group acting for private equity firm Lone Star Funds in a $500m Singapore-seated ICC arbitration against Hana Financial Group; the dispute arose from Hana’s acquisition of a controlling interest in Korea Exchange Bank in 2012. Also notable is that the firm has been instructed in groundbreaking investor-state disputes, as has been evidenced by its work acting for Elliott Funds and Mason Capital Management LLC in separate investor-state arbitration cases against the Republic of Korea. Young Suk Park chairs the international arbitration practice, having joined from Atinum Partners in October 2018. Dong-Seok (Johan) Oh, who joined from Bae, Kim & Lee LLC in March 2019, is the overall head of the dispute resolution practice (which covers both international arbitration and cross-border litigation). John M. Kim and Byungsup F. Shin left to establish Kim & Partners.

Corporate and M&A: local firms Tier 3

Although KL Partners is a relatively new firm (having been established in 2015), it has already established an excellent reputation among many of the largest and most active domestic and international private equity firms; clients include KKR, Baring Private Equity and IMM. It also has a strong client following among corporates. In addition to winning work in its own right, the firm generates a significant amount of referral work from foreign law firms. In 2018, practice head Seong Hoon (Sean) Yi was the lead adviser to KTB Private Equity (KTB) on the circa $230m sale of shares in Junjin Heavy Industry Co. Ltd. to Well To Sea Investment and Motrex. In another highly-publicised transaction, Eun Nyung (Ian) Lee and others assisted Shangdong Ruyi Group with acquiring Lycra companies from Koch Industries for over $2bn. The team has been strengthened recently by the arrivals of Seonho Kim and Young Suk Park from SEUM Law and Atinum Partners respectively. Other practitioners in the group are Jisun HwangDoo-Ri Jeong and In Sung KimTim Kim has left to help establish Kim & Partners.

Dispute resolution: local firms Tier 3

KL Partners has a diverse litigation practice, which covers general commercial disputes, intellectual property matters and securities and finance litigation. The firm notably stands out representing Korean and foreign clients in cross-border litigation; Ki Seong Park and managing partner Beomsu Kim are representing Xangbo Global Markets Pte. Ltd. (Singapore) in a $26m lawsuit against MJB and Woori Bank where a Korean company had fraudulently diverted funds to its own account. In another matter, which is pending before the Supreme Court of Korea, Kim, Park and Eun Nyung (Ian) Lee are leading the advice to GEA Farm Technologies GmbH on a $35m lawsuit against Korean distributor Sesame W.S. Trading; the case concerns the wrongful termination of exclusive distribution rights granted by the client to Sesame W.S. Elsewhere, highly sensitive criminal cases/investigations are another bedrock of the firm's contentious work, and are a key area of growth. Dong-Seok (Johan) Oh, who is a recent hire from Kim & Chang, is the overall head of dispute resolution. Park is the chair of the litigation practice. Recent hires Seonho Kim and Young Suk Park, who joined from SEUM Law and venture capital firm Atinum Partners respectively, are also key names to note. Heedong Hwang has left to help establish Kim & Partners.
