Overview
Yulchon secures its place in the ‘Outstanding’ band for competition, dispute resolution, M&A, private equity and tax this year. Its famed dispute resolution practice has more than 250 professionals and keeps apace with an evolving market, creating new disputes practice areas that are novel and innovative.

The firm has strategically bolstered its team through key hires across various practice areas. The competition/antitrust practice has been particularly active in recruitment, welcoming Genny S Kim from Jipyong as a partner. However, the practice also saw the departures of Hyo Sung Kim in June 2024.

The dispute resolution practice underwent substantial growth, welcoming three new partners including Jinsub Kim from Samsung C&T legal team dispute resolution TF, Shi Won Lee from a role as Secretary to the President for Public Office Discipline, and Jae Hwan Shin from National Court Administration. Two partners departed – Rak Hyun Kim to SK Group and Jae Eok Park.

In the tax practice, Yulchon made strategic hires including Kwang Lae Cho from the Tax Tribunal, Jung Wook Jun from Samsung Life Insurance, and Se Bin Lee from Supreme Court of Korea.
