1. About ตลาดตราสารทุน Law in Bangkok, Thailand

ตลาดตราสารทุน refers to the equity market where shares and equity-related securities are issued and traded. In Bangkok, regulation is primarily driven by the Securities and Exchange Commission Thailand (SEC) and the Stock Exchange of Thailand (SET). Listing and trading on SET or the Market for Alternative Investment (MAI) require strict disclosure, governance, and compliance standards.

For residents of Bangkok, understanding how filings, disclosures, and trading rules work is essential before raising funds or purchasing listed securities. Regulators continually refine disclosure standards and governance expectations to strengthen market integrity.

2. Why You May Need a Lawyer

• Preparing an IPO or MAI listing for a Bangkok startup - If a Bangkok-based company plans to raise capital by issuing new shares, a lawyer coordinates with the SEC and SET, drafts the prospectus or information memorandum, and ensures compliance with listing rules. Expect 6-12 weeks for initial regulatory clearance, depending on complexity.
• Executing a private placement or rights issue - When a Thai company offers securities to investors, counsel handles due diligence, subscription agreements, and regulatory disclosures. This minimizes the risk of misstatements or insufficient disclosures that could trigger penalties.
• Advising a foreign investor buying Thai listed shares - A cross-border acquisition or stake purchase requires compliance with the Acquisition of Shares in Listed Companies Act and anti-trust review if applicable. Legal counsel helps structure the deal, negotiate terms, and prepare tender offers when required.
• Managing corporate governance and disclosure obligations - After listing, Bangkok issuers must comply with governance and ongoing disclosure rules. A lawyer helps implement board processes, related-party transaction controls, and annual reporting timelines.
• Handling insider trading or market misconduct investigations - If you suspect non-public information has been used improperly, a securities attorney guides response strategies, internal investigations, and potential regulatory reporting.
• Negotiating share purchase agreements in M&A - For Bangkok-based deals, counsel conducts due diligence, drafts sale and purchase agreements, and aligns closing conditions with issuer requirements and regulatory approvals.
