Professional membership

Member of the Institute of Legal Education of the Thai Bar Under Royal Patronage (เนติบัณฑิตยสภา ในพระบรมราชูปถัมภ์)

Lecturing and academic work

Eksiam Chaisorn lectures as a guest speaker on law at Rajamangala University of Technology, Sripatum University, Suan Dusit University and Panyapiwat Institute of Management, and for government agencies, professional associations and private organisations, on topics including transfer pricing, international tax and the Personal Data Protection Act B.E. 2562 (2019).

The firm's policy requires its legal consultants to lecture, write and carry out research alongside advising clients. Articles published on the firm's websites therefore cite statutes, Supreme Court judgments and foreign law checked against the original sources.

Role in technology law policy

Eksiam Chaisorn has given expert views on the Personal Data Protection Act B.E. 2562 (2019) to the Committee on Public Health of the House of Representatives of Thailand, and has taken part in national technology policy meetings with the relevant agencies. His advisory work now centres on technology law and technology-related law.

Technology-related matters, such as the processing of personal data, electronic transactions and computer offences, usually turn on electronic evidence. In disputes of this kind the conduct of proceedings therefore comes first, from preserving the evidence to presenting it in court.

Areas of advice

Eksiam Chaisorn advises through Eksiam & Partners Co., Ltd. on technology law and personal data protection, Thai tax law and international tax, partnership and company law, defamation, and legal and tax questions for foreigners in Thailand. In technology-related disputes the conduct of proceedings is treated as the first priority.

In practice as a legal and tax consultant since 2000 (B.E. 2543), covering preventive planning and civil, criminal, tax, family and international commercial litigation in the courts of general jurisdiction and the specialised courts. Current areas of advice:

  • Technology law, personal data protection and technology-related disputes
  • Thai tax law, international tax, tax assessment appeals and tax litigation
  • Formation and structuring of partnerships and companies, business contracts and foreign investment
  • Defamation, including online defamation
  • Visas, tax, property and wills for foreigners retiring in Thailand

Eksiam & Partners Co., Ltd. has handled more than 1,500 client matters. The figure counts all types of work of the firm, not tax cases or any single type of case alone.

Legal advisory work is subject to a duty of confidentiality to clients. This page therefore does not name clients or describe the matters handled.

Writing and websites

Eksiam Chaisorn writes and is responsible for the content of nine websites: five law websites of the firm, covering legal theory, tax law, business law, defamation and law for foreign retirees in Thailand, and four websites on community life, travel and photography, including the photographic journal Fluiréa.

Advisory approach

The advisory approach of Eksiam Chaisorn follows preventive law, rooted in the work of Louis M. Brown, and proactive law as developed by Helena Haapio: rights, duties and risks are set out clearly at the start, so that disputes are prevented before any need to go to court.

Good problem-solving does not stop at the question asked; it identifies every connected dimension before concluding. Criminal law, family law, business law, tax, accounting, governance and risk management are therefore considered together rather than one at a time.

What good planning achieves

Less uncertainty, fewer disputes, preserved relationships and controlled costs, compared with dealing with problems at a late stage.

Legal knowledge as strategy

Robert C. Bird argues that legal knowledge is not only a cost of avoiding mistakes but a strategic resource that reduces uncertainty and transaction costs.

When a dispute arises from facts outside anyone's control and negotiation, dispute resolution or litigation becomes necessary, the firm's legal consultants and lawyers begin with the facts, review documents and evidence systematically, and set a course for the particular matter. Clients are told the position of their matter plainly, on the facts and the law.
