Attorney Choi Jin-sook is a specialist in financial law. Ms. Choi completed the 28th class of the Judicial Research and Training Institute and began her career as a finance lawyer at HMP Law. She joined Barun Law LLC in 2018 as a finance specialist and has since advised on a broad range of financial matters, including project finance, real estate finance, structured finance, asset securitization, overseas investments, real estate funds, real estate investment trusts (REITs), and non-performing loans (NPLs), covering both specialized and general finance. Building on her advisory expertise, she also actively handles financial disputes, including litigation and arbitration.

Since 2019, when a series of distressed private equity funds such as the Lime Fund and Optimus Fund faced mass redemption suspensions, Ms. Choi recognized the gravity of the situation based on her experience during the 2007 Lehman Brothers crisis. She promptly organized a task force and established a distinctive competitive edge in the fund market. As head of the firm's Distressed Private Equity Fund Response TF, she worked closely with accounting firms and overseas law firms to conduct due diligence on numerous overseas distressed funds and to advise on recovery of offshore claims. More recently, in response to the evolving financial environment, she has expanded and reorganized the team into the Alternative Investment Recovery Advisory TF. The team now provides advisory services in areas including recovery of overseas real estate-related claims, restructuring of distressed project finance (PF) sites, recovery strategies for creditor financial institutions in insolvency proceedings, and transactions involving financial institutions' special assets such as NPLs.

As head of the firm's Financial Regulatory Response Team, Ms. Choi leads a multidisciplinary group comprising former judges and prosecutors, financial regulatory specialists, attorneys with extensive experience at institutions such as the Financial Supervisory Service and the Korea Exchange, and certified public accountants. Through this collaborative structure, she has expanded the firm's capabilities in areas such as licensing and registration of financial institutions, regulatory inspections and sanctions, listing maintenance, accounting supervision, interpretation of financial laws and compliance, and financial investigations, litigation, and disputes.

Ms. Choi is also actively engaged in external activities, serving as a member of the Asset Management Committee of the National Housing Fund, the Investment Review Committee of Korea Post Finance, the Alternative Investment Committee of the Korea Federation of SMEs Mutual Aid ("nolan-usan"), the Sanctions Review Committee of the Financial Supervisory Service, and the Central Land Tribunal. She was recognized as a "Leading Lawyer" in Securities and Finance by Legal Times in 2022 and 2023.
