We provide advice to ensure that parties involved in domestic or cross-border over-the-counter derivative transactions, as well as on-exchange derivative transactions traded on the KRX and foreign exchanges, are not in violation of domestic regulations, regardless of the type of underlying assets such as stocks, bonds, commodities, and credits. Additionally, we offer advice on the impact of changing international regulatory environments on domestic and international derivative transactions. Our advisory services cover a wide range of activities, including consultation on transaction structuring, negotiation of transaction terms, drafting of contracts and related documents, and handling of reporting to government agencies or obtaining government agency approvals for transactions.

In the event of regulatory violations in transactions, if sanctions procedures are initiated by domestic financial supervisory authorities, our experts at Song & Choi collaborate with internal or external specialist groups to effectively identify issues and develop defense strategies. Furthermore, we provide representation for the parties involved throughout the sanctions process. Moreover, when civil or criminal proceedings are initiated regarding derivative transactions, a deep understanding and rich experience in such transactions are essential. In such cases, our firm undertakes the representation of clients in civil and criminal proceedings to ensure the best possible outcome.
