South Korea > Shipping: local firms

Kim & Chang‘s market-leading reputation in shipping is underpinned by its extensive coverage of a full range of shipping disputes, where it acts for domestic and foreign shipowners, P&I clubs and insurance companies. Byung-Suk Chung leads the team, which is experienced in contentious matters involving shipbuilding contracts, accidents at sea, charter party disputes, insolvency proceedings and insurance issues. Chung’s standing in the industry is reflected by the fact that he serves as the president of the Seoul Maritime Arbitration Association, among other notable roles. Chul-Won Lee and Sungjean Seo are advising a client on LMAA arbitration proceedings arising from a dispute over shipbuilding contracts for the engineering and construction of four semi-submersible drilling rigs. Clients also benefit from the expertise of Jin Hong LeeJae-Bok Lee and Joon Hwan Park.

South Korea > International arbitration

Kim & Chang‘s network, broad industry coverage and ability to leverage cross-practice support enable it to assist clients with all complex issues associated with international arbitrations and related civil/criminal proceedings. Byung-Chol Yoon and Eun Young Park jointly lead the widely respected team in Seoul, which is increasingly active in arbitrations in the shipbuilding, offshore and energy spheres. Byung-Woo Im and Kay-Jannes Wegner (who both co-head the specialist construction arbitration practice) advised a Korean engineering and construction company on a Seoul-seated ICC arbitration, which was centred on a dispute with another Korean construction company over a supply contract for major equipment for one of the biggest power and water projects in the Middle East. In another matter, Yoon, Una Cho and others are representing four different financial investors as the claimants in an ICC arbitration against an individual shareholder of a life insurance company; the dispute concerns the individual shareholder’s alleged failure to honour a put option exercised by the financial investors under a shareholders’ agreement. Chul-Won Lee‘s wide-ranging experience includes disputes involving shipbuilding, international trade, insurance and M&A. Other names to note include Joel RichardsonSungjean Seo, and Hye Sung KimDon Jeon is a recent hire from Freshfields Bruckhaus Deringer.
