Seum Law

South Korea



Seum Law is a boutique law firm that is focused on the technology and telecommunications sphere, and is recognised for advising startups and venture capitalists. It remains strong in the ‘Highly recommended’ tier for technology and telecommunications, an acknowledgement of its commitment to this area, particularly for early-stage players. The firm does not profess to compete with its larger counterparts for big-ticket mandates, but rather has steadily increased its profile among mid-market clients. Managing partner Hoseok Jung and partner Joonbum Cheon lead the firm. It welcomed Hyun Nam as a dispute resolution partner in March 2023.

Client feedback

“The most positive attribute of the firm is that senior lawyers lead the project while communicating directly with clients. In many cases working with other law firms, inexperienced associates handle most of the work and, as a result, client feedback is not immediately reflected, and sometimes completely wrong legal advice is delivered to the client. On the other hand, Seum Law maintains the high quality of legal services by having experienced senior lawyers pay close attention to the project.” – Corporate and M&A

“Timely and professional response.” – Media and entertainment

Seungkyu Byun

“He is very rational when working and very considerate when communicating with clients. Since most lawyers passively provide legal services within the scope of work requested by the client, if the client fails to properly determine the scope of work, the final result often comes out wrong. He helps the client step by step in properly determining the scope of work. He communicates with clients from time to time even while working, and actively responds to clients' feedback. As a result, the results of the legal services provided by him were always satisfactory.”

Jungok Yun

“Attention to client's needs and innovative/professional consultation.”
