SEUM
SEUM is a boutique law firm founded by attorneys from Korea’s top firms
We provide general corporate and litigation services in a variety of practice areas and are the leading Korean law firm with respect to startup companies, technology companies and venture capital funds.
SEUM works with Korean and international clients on a regular basis, handling a broad range of local and cross-border matters, to provide clear and practical advice. Some of our clients include investment funds such as 500 Startups, Legend Capital, and Mirae Asset; large corporations such as Hanwha, Naver, WeMakePrice, and Kakao Mobility; as well as startup companies such as Zipdoc, Fly & Company, MangoPlate and Stradvision. SEUM was one of 15 law firms featured in Asian Legal Business's "Firms to Watch" list for 2017 and selected in 2017 for the second consecutive year by Asian Legal Business as one of the best boutique law firms in Korea.
We Are Different
The founders of SEUM decided to leave established law firms to break-free from the problems that continue to plague the traditional Korean law firm. Here are some of the reasons we are “different":
We Care
Whether the client is a bootstrapping entrepreneur, a company on the verge of an IPO, or a conglomerate with offices around the world, SEUM provides a high level of focus, professional care and dedication. We truly enjoy working with our clients to help them achieve their business objectives.
Efficiency
We are not anchored to the billable hour model, which can incentivize wastefulness and increased fees. We prefer fee arrangements that align our interests with those of our clients, and create a more efficient and effective work dynamic.
SEUM’s partners strongly promote a working style that focuses on results and not form.
Responsiveness
We are proactive in keeping our clients informed about the progress of our work, and responding to clients promptly. If we are unable to provide a complete response to a query, we will let you know that we are working on a response. We believe that these details in client communications are important.
He is a lawyer with the best expertise and experience in the industry, and he always puts himself in the client's shoes and shows sincerity. 
Chambers Global 2025
Seungkyu Byun 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.

Asialaw 2024 Rankings
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.
