Police raid 600-million-baht Samut Sakhon factory and arrest four as Thailand investigates 10,000 suspected nominee companies

Thai authorities have sharply escalated their crackdown on illegal foreign business ownership this week, highlighted by a raid on a 600-million-baht rubber factory in Samut Sakhon. Police arrested two Chinese nationals—including a fugitive owner—and two Thais on September 16 for allegedly operating through an illegal nominee structure, according to reports from The Pattaya News and The Thaiger.

The raid is not an isolated incident. It coincides with a sweeping nationwide initiative targeting foreigners who use Thai citizens as proxy shareholders to bypass foreign ownership restrictions.

A multi-agency crackdown

The scope of the current enforcement is unprecedented, involving multiple government departments and targeting both corporate structures and immigration fraud. According to Thai-language media and official announcements, the crackdown includes:

• 10,000 companies under scrutiny: Authorities are actively investigating over 10,000 corporate entities suspected of using Thai nominees, according to Bangkokbiznews.
• DSI intervention in Pattaya: The Department of Special Investigation (DSI) has formally opened a special case to dismantle illegal nominee business networks in Pattaya, as reported by Nation Thailand.
• Stricter citizenship checks: The government is implementing a mandatory one-year retrospective background check for Thai citizenship applications to close loopholes used by foreign nominees, according to Thai Post.
• Birthright fraud prevention: The Ministry of Public Health is cracking down on private hospitals to stop the fraudulent registration of Thai citizenship for children using "fake fathers," reports Bangkokbiznews.

What this means for foreign business owners

If you operate a business or hold property in Thailand through a Thai limited company, the regulatory environment has fundamentally shifted. The days of using a local law firm to provide passive Thai shareholders are over.

Authorities are no longer just looking at the paperwork; they are investigating the financial reality behind the shares. Thai shareholders must be able to prove they had the legitimate financial means to purchase their equity and that they receive actual dividends from the business.

Foreigners relying on nominee structures to hold land, villas, or restricted businesses should urgently audit their corporate compliance. If your Thai partners cannot demonstrate genuine financial involvement, you are at risk of investigation, asset seizure, and deportation. Ensure your company's financial trails, shareholder agreements, and tax filings reflect a legitimate joint venture rather than a proxy arrangement.
