Dong Ha Kim started his career as a lawyer in 1996 at Lee & Ko, working with 20-plus lawyers. At that time, major Korean law firms had, on average, no more than 20 lawyers whereas now, the 10 biggest firms in Korea have over 100 lawyers each; Lee & Ko, the country's second-biggest law firm, has over 600 professionals. For the past 20 years, Dong Ha Kim has dedicated his passion for the law, and his talent, to clients and to Lee & Ko itself.
Between 1996 and 2006, the firm's relatively small scale meant lawyers worked across several areas of practice, such as, among others, contract review; civil and criminal litigation; tax; labour; and intellectual property. This multifaceted approach enables Dong Ha Kim to effectively assist his clients' various and complex legal needs.
At present, Dong Ha Kim focuses on litigation and arbitration in relation to inheritance; Protestant Church disputes; media; and healthcare. As the Korean economy continues grow, the scale of inheritance becomes bigger than ever. The communication revolution, particularly the internet, has given every aspect of the media the potential to negatively affect the life of a company or individual. Problems concerning inheritance and media relations require a range of sophisticated legal skills, knowledge and experience; as such, Dong Ha Kim's career as a generalist, in combination with his client-friendly approach, gives clients deep reassurance on almost every case. The majority of those he assists are long-standing clients requesting legal opinion and advice on a variety of issues.
Between 2004 and 2017 he represented a former reverend of GwangSung Church in a case against the succeeding reverend, in a matter that involved 55 litigations over 10 years. He also represented Yang Ho Cho, the president of Korean Air, in a 15-year dispute with a former Korean Air pilot that ended in 2017. The pilot initiated the dispute with claims that Cho had breached his employment rights, and embarked on an international campaign that included a protest at the UN headquarters in New York. Over the past ten years he has acted for various entities in disputes concerning press coverage, including including Korean Air; the Westin Chosun Seoul Hotel; and a renowned cardiologist. In addition, he has acted in medical malpractice litigations representing Yonsei University Health System; Asan Medical Centre; Myongji Hospital, and others; he has also represented private patients in disputes with hospitals.
