Thai authorities have escalated their enforcement against illegal foreign property ownership, charging 85 individuals following raids on 12 properties in Pattaya and arresting 13 foreign nationals in Hua Hin.
The coordinated Pattaya operations targeted properties worth a combined 800 million baht. According to the Thai Examiner, police are probing suspected foreign nominees and warning that illegal landholdings may face compulsory sales within 180 days if violations are proven.
These regional sweeps are part of a broader mandate. A nationwide operation is currently targeting 1,397 specific entities suspected of using Thai citizens as business proxies to bypass local property laws, according to Thailand Business News. The government has ordered these targeted investigations to conclude by December 2026, identifying land worth $417 million across 875 hectares for potential forced sale, as reported by Brief Asia.
What this means for foreign property owners

If you own property or operate a business in Thailand through a Thai limited company, the compliance landscape is shifting from paper requirements to practical substance.
According to legal advisory firm Mahanakorn Partners, authorities are increasingly testing whether the funding, control, and economic rights support the structure recorded on paper, rather than just checking for a formal 51/49 Thai-majority ownership split.
To enforce this, new regulations require Thai partners in foreign joint ventures to provide extensive bank records demonstrating their ability to fund their investment shares, according to Thai Times.
If you are currently buying property or reviewing an existing corporate structure, you should:
- Verify funding trails: Ensure your Thai partners can legitimately prove the source of their investment capital with bank records.
- Review company control: Avoid structures where foreign shareholders hold disproportionate voting rights or dividend preferences that clearly bypass the 49% foreign ownership limit.
- Prepare for audits: Companies holding land, particularly those among the 1,397 targeted entities in tourist hotspots, are at high risk for inspection before the December 2026 deadline.
Foreigners found guilty of utilizing illegal nominee structures face severe penalties, including the forced sale of the assets in question.
