Siriwan has extensive knowledge of and experience with a broad range of legal issues; she specializes in competition law, M&A transactions, anti-dumping regulations, corporate and commercial law, foreign business law, and work permits & immigration.

Siriwan joined the Corporate & Commercial Practice Group in May 2016. Prior to joining our firm, she accumulated 10 years of experience in the legal industry. She began her career as a litigation trainee at a well-known bank in Thailand, before making the transition to law firm work, where she specialized in intellectual property (IP) and corporate law.

Siriwan provides ongoing advice to a range of domestic and international clients (corporate and individual) on the complex legal requirements governing limited companies and public enterprises. She also advises publicly listed companies on compliance with the regulations establish by the Stock Exchange of Thailand and the Securities and Exchange Commission. Her expertise encompasses tender offers, acquisition and disposal of assets, corporate governance, and commercial and contractual transactions as well as disputes. She also performs comprehensive legal due diligence, assists with complex mergers and acquisitions, and advises clients on investment law and compliance issues, including document drafting and negotiations.

She handles the competition/antitrust matters for our Thailand office, and is recognized as a pioneer in this practice area in Thailand, for which the relevant legislative framework entered into effect in 2020 (with a potential amendment currently under consideration). She advises on trade competition, including abuse of dominant position, mergers and acquisitions, unfair trade practices, cartels, and unreasonable agreements with offshore business operators.

Siriwan is a distinguished speaker on antitrust, competition, and commercial contracts, and serves as a part-time lecturer at the University in Thailand, where her courses focus on contract drafting and negotiation.
