Company registration services

Public Limited Company Registration

Public limited companies are registered under the Public Limited Companies Act 1992, either newly or by converting a private company. Registration does not authorise public share offerings, which need separate SEC approval.

Public companies face stricter rules on promoters, boards, meetings and disclosure than private companies. This page reviews the route before documents are prepared and is not investment or listing advice.

New incorporation or conversion

A new PLC goes through promoters, a memorandum and a statutory meeting; an existing private company can convert by shareholder resolution. Conversion requires review of capital, debts and contracts.

Promoters and board

The law sets promoter numbers and eligibility, minimum directors and the share of directors resident in Thailand. Check the current Act including amendments.

Registration is not a public offering

Offering shares to the public requires SEC approval and a registration statement. Listing on the stock exchange is a further step.

Meetings and disclosure

PLCs must hold annual meetings, publish annual reports and file audited statements on time. Plan company-secretary functions from the start.

Foreign shareholders

Foreign holdings still affect alien status under foreign-business law, and articles may cap foreign ownership. Review before structuring.

Overseas documents and signatories

Overseas promoters or directors may need certified and translated documents. Sequence signing to meet meeting dates.
