Overview
Kudun and Partners is a young and energetic full-service firm that has grown rapidly in the past few years, pulling in talent from competitors and being hailed as a firm to watch by peers. The firm has established a dedicated China practice staffed with native Chinese speakers and it is now part of the legal network World Services Group, as the Thailand representative. Partner and key contact Kudun Sukhumananda has expertise in capital markets, corporate and M&A, banking and finance, real estate, infrastructure funds and energy. Over the past 12 months, the firm welcomed Putthimes Thanarersk as Senior Counsel in June 2025, who joins from the Securities and Exchange Commission and brings significant expertise to the firm's capital markets practice. The firm also saw the departure of Ekachai Chotpitayasunon, who left his position as Partner in the capital markets practice in October 2025 to join Medium.

Client feedback

"The firm has a strong commercial understanding and provides practical legal advice. The team is responsive, attentive to clients' needs, and able to handle complex matters efficiently. The partners are hands-on and provide good support throughout the engagement." – Capital markets

"Kudun and Partners demonstrates strong legal expertise, commercial awareness, and responsiveness. The team provides clear, practical, and business-oriented advice, particularly in reviewing and negotiating construction-related contracts. They are effective in identifying key legal and commercial risks, explaining complex issues in a straightforward manner, and delivering timely support that facilitates efficient decision-making." – Construction

"Understood our needs well." – Corporate and M&A

"One of the things I value most about Kudun is that they genuinely put their clients first. Their advice is always practical, commercial, and tailored to what we are actually trying to achieve, rather than being purely theoretical or academic. As a Thai law firm, they have a deep understanding of the local business environment and the nuances of operating in Thailand, which is something that many international firms simply cannot replicate. They understand not only the law, but also how things work in practice. Another key strength is their strong relationships with regulators and government authorities, which allows them to navigate complex issues efficiently and provide commercially sensible solutions — a real advantage when dealing with challenging matters." – Corporate and M&A

"Knowledge of local law, ability to communicate clearly in English, and commercial in advice." – Corporate and M&A

"Excellent client skills and very practical." – Dispute resolution

"Their team is highly responsive, commercially minded, and easy to work with. They communicate clearly, manage client expectations well, and maintain close coordination throughout the engagement, resulting in smooth collaboration and consistent delivery of practical, business-oriented advice." – Energy

"Responsive." – Media and entertainment

"Primarily, they were able to help us where previous firms could not. We engaged another firm earlier to help us obtain various banking licenses in Thailand and none of those firms were able to deliver, while Kudun and Partners delivered within budget and timeline." – Regulatory

Chai Lertvittayachaikul

"Chai is responsive, practical, and easy to work with. He understands our business needs and is able to explain legal matters clearly, willing to discuss issues in detail when needed and providing useful recommendations."

"Chai is a very reliable and easy lawyer to work with. He is responsive, practical, and understands well how to handle cross-border matters. He communicates clearly and is good at keeping things moving, which makes coordination between teams smooth and efficient."

EMI Rowse

"Very practical and hands-on."

Troy Schoonemen

"Commercial and highly responsive."

Kudun Sukhumananda

"Good listener with strong defending ability."

"Kudun is always responsive and easy to work with. He and his team understand our business and provide practical advice that is commercially workable. He and his partner Thitawan are hands-on and approachable, and we appreciate their attention to detail, timely support, and ability to put themselves in our shoes."

"He is highly approachable, takes the time to understand our business, and puts himself in our shoes when providing advice. He is also very solutions-oriented, often bringing innovative ideas to the table while keeping sight of the bigger picture and our commercial objectives."

Thanyaluck Thongrompo

"Excellent communicator, meets deadlines and delivers results."
Linked Reviews
Capital markets (asialaw)
Work highlights

Acting as Thai legal counsel to a consortium of strategic shareholders from Hong Kong, Singapore, and Thailand on the IPO and Main Board listing of IFBH — parent company of the internationally recognised coconut water brands if and Innococo — on the Hong Kong Stock Exchange. The IPO priced at HKD$27.80 per share and closed at HKD$39.50 on its first trading day, an uplift of over 40%, achieving a market capitalisation of approximately HKD$10.85 billion ($1.38 billion). The deal is widely regarded as a milestone transaction, being one of the few Thailand-linked listings in recent years on the HKEX outside of Greater China.
Corporate and M&A (asialaw)
Work highlights

Representing the founders and longstanding leaders of Regent's International School Bangkok — one of Thailand's most prestigious day and boarding schools, founded in 1995 by Dr. Virachai Techavijit — in its landmark strategic partnership with Nord Anglia Education, the London-based global leader in international education operating across 36 countries. Completed in August 2025, the transaction enables Regent's Bangkok to retain its unique ethos and identity while integrating into Nord Anglia's global family of schools, unlocking access to world-class collaborations with institutions such as MIT, UNICEF, and The Juilliard School. The deal is one of the most significant education-sector investments in Thailand in recent years, reflecting growing international investor appetite for the Thai international school market, with Baker McKenzie acting on the other side for Nord Anglia Education.
Dispute resolution (asialaw)
Work highlights

Representing a former independent director of a public listed company in a high-profile class action lawsuit alleging the solicitation of securities sales using false information, with damages sought against the company of up to THB 4 billion (approximately $120.5 million) — potentially the largest class action claim in Thailand's history if certified by the court. The firm is leading the defence of the client, who as an independent director with no material or pecuniary relationship with the company or its related parties, is challenging their inclusion in the claims and arguing for exemption from liability. The case is ongoing and is closely watched for the precedent it may set in Thailand's securities and capital markets landscape.
Restructuring and insolvency (asialaw)
Work highlights

Advising TTCL Public Company — a publicly listed Thai–Japanese EPC contractor and Thailand's first fully integrated EPC player — on the successful filing and court acceptance of its business rehabilitation petition under the Thai Bankruptcy Act by the Central Bankruptcy Court on 3 November 2025. The matter involves indebtedness exceeding THB 14 billion (approximately $448.5 million) owed to a highly complex creditor base of approximately 4,000 creditors, including financial institutions, trade creditors, and multiple series of bondholders represented by security trustees. The court's acceptance placed TTCL under rehabilitation with an automatic stay, enabling the company to continue operations while a structured restructuring is pursued. The firm is advising across the full rehabilitation process, including court submissions, creditor coordination, and engagement with the court-appointed planner. Given the scale of indebtedness, the complexity of the creditor structure, and TTCL's strategic significance to Thailand's infrastructure and EPC sectors, the case is widely regarded as a landmark rehabilitation proceeding and a reference point for the effective use of Thailand's rehabilitation regime for strategically important listed corporates.
