According to Department of Business Development (DBD) data from August 2026, 36,277 entities with foreign participation currently hold land in Thailand. Of those, 31,516 have foreign shareholding at or below 49%, confirming that this ownership structure remains fully legal under Thai law. The critical question is not the shareholding ratio itself, but whether the Thai co-shareholders invested genuine, traceable funds and play an active role in company management.
We monitor this subject closely because any foreign investor acquiring a villa in Phuket or Koh Samui through a Thai company needs to understand precisely which documents separate a legitimate joint venture from a nominee arrangement. Penalties for a proven nominee structure reach up to 3 years' imprisonment, substantial fines, and a forced sale of the property within 180 days of a Department of Lands ruling.
The DBD investigation covers 16 provinces, including Phuket, where the concentration of foreign-participation companies is among the highest in the country. For any international buyer, that means one thing: financial documentation must be complete from day one.
Quick answer
- A Thai company with foreign shareholding up to 49% can legally hold land, provided the Thai shareholders invested their own funds and genuinely participate in management
- DBD data from August 2026 covers 36,277 entities; the central criterion in any review is the source of the Thai shareholders' capital
- Nominee penalties: up to 3 years' imprisonment, fines up to 1 million THB under the Foreign Business Act, and forced land disposal within 180 days
- Key protective documents: verified bank transfers from Thai shareholders, a shareholder agreement, shareholders' meeting minutes, and Thai shareholders' personal tax returns
- In Phuket and Koh Samui, enforcement activity is concentrated in high-development zones: Bang Tao, Layan, Kamala on Phuket; Bophut and Maenam on Koh Samui
- Companies with foreign stakes above 49% (4,761 entities per DBD data) operate legally primarily under BOI or Industrial Estate Authority permits
Options and scenarios
Option 1: Legitimate joint venture with Thai shareholders
The structure in which Thai shareholders hold 51% or more of shares, financed from documented personal funds, is the standard legal route. The foreign party holds up to 49%, but can negotiate preference shares carrying enhanced dividend rights or voting weight on defined matters.
In practice, across our on-the-ground monitoring in Phuket, we see structures where the Thai co-shareholder is an established business person with a tax history that supports the capital contribution. Based on our estimates, an authentic joint venture requires the Thai shareholder to demonstrate a source of funds of at least several hundred thousand THB to several million THB, depending on the property value.
Key documents required:
- Bank transfer records from Thai shareholders into the company account (cash contributions are a red flag, not a safe alternative)
- Shareholder agreement covering rights, obligations, exit mechanisms, and profit distribution
- Shareholders' meeting minutes documenting genuine business decisions over time
- Annual personal income tax returns (PND 90/91) of Thai shareholders, confirming income consistent with the capital contribution
- Annual financial statements and balance sheet filed with DBD
Option 2: Structure carrying nominee risk
A situation in which Thai shareholders have no independent financial means, take no part in company decisions, and cannot explain the origin of their capital. Even when the formal split reads 51/49, regulatory authorities treat this as a nominee arrangement.
Red flags we identify in cases reviewed across Phuket and Koh Samui:
- Thai shareholders are individuals whose annual income clearly cannot cover the value of shares they supposedly contributed
- No bank transfer records from Thai shareholders exist at all
- A blanket power of attorney granted to the foreign party for all company matters
- Thai shareholders have signed undisclosed agreements to transfer shares on the foreign party's demand (so-called side agreements)
- The company conducts no business activity beyond holding a single property
Option 3: Leasehold as a nominee-free alternative
For investors unwilling to involve Thai co-shareholders, a land lease (leasehold) for 30 years with a renewal option remains the most straightforward legal path. In Koh Samui, particularly in Bophut and Maenam, we observe growing interest in this structure among European buyers.
Alternatively, purchasing a condominium under freehold title (foreign ownership of up to 49% of total building floor area) removes nominee risk entirely, though it limits the buyer to apartment units rather than villas.
Comparison table
| Parameter | Legitimate joint venture (up to 49%) | Nominee structure | 30-year leasehold | Condo freehold |
|---|---|---|---|---|
| Land ownership | Yes, via the company | Nominally yes, with loss risk | No, leasehold interest only | N/A (shared land title) |
| Criminal exposure | Minimal with full documentation | Up to 3 years' imprisonment | None | None |
| Forced sale risk | None if shareholders are genuine | Yes, 180-day disposal order | N/A | N/A |
| Structure cost (estimate) | 80,000 - 200,000 THB (incorporation + legal) | Similar upfront, hidden risk later | 30,000 - 80,000 THB | No additional cost |
| Thai shareholder documentation | Bank transfers, PND returns, active involvement | Absent or fabricated | N/A | N/A |
| Effective control over property | High (via shareholding and agreement) | Superficially high, structurally fragile | Moderate (depends on lease terms) | Full |
| Exit and resale | Share sale or asset sale | Blocked following enforcement | Lease assignment | Direct resale |
Risks and mistakes
Failure to document the Thai shareholders' source of capital is the single most common error we identify among foreign investors acquiring property in Phuket. Many assume that a 51/49 share split is sufficient on its own. DBD reviewers, however, look not at the ratio on paper but at the actual flow of money. If a Thai shareholder holding 51% cannot demonstrate where the funds to subscribe those shares came from, the entire structure is reclassified as nominee.
Blanket powers of attorney granted to the foreign party are a persistent red flag. When a Thai shareholder signs a general power of attorney effectively handing management of the company to the foreigner, investigators treat that as direct evidence that the Thai participation is nominal.
Side agreements on share transfers - undisclosed contracts in which the Thai shareholder commits to transferring shares at the foreign party's request - constitute explicit nominee evidence in DBD proceedings and are treated as such in enforcement cases.
No operational activity beyond property ownership draws scrutiny. In our data sets, companies conducting genuine business activity, such as rental management or short-term letting, face a materially lower probability of triggering a nominee review compared with single-asset holding vehicles with no revenue.
Outdated financial filings are also a trigger. A company that fails to submit annual financial statements to DBD automatically appears on the verification list. As of 2026, delinquent filings account for a notable share of entities currently under review.
Property consequences after a nominee ruling: if nominee status is proven, the Department of Lands issues a forced-sale order requiring disposal of the land within 180 days. If no sale occurs within that window, the land may revert to the state. Criminal liability for those involved runs in parallel.
FAQ
Is a Thai company with up to 49% foreign shareholding legal?
Yes. Per DBD data from August 2026, 31,516 such entities operate legally in Thailand. The condition is that Thai shareholders must have contributed documented personal funds and must genuinely participate in company management.
Which documents protect against a nominee finding?
The essential set includes: bank transfer records from Thai shareholders, their annual personal income tax returns (PND 90/91), a shareholder agreement, shareholders' meeting minutes, and annual financial statements filed with DBD.
What penalties apply to a nominee structure in Thailand?
Violation of the Foreign Business Act carries up to 3 years' imprisonment and fines of up to 1 million THB. Separately, the Department of Lands can issue a forced-sale order requiring disposal of the land within 180 days.
Do DBD investigations cover Phuket and Koh Samui?
Yes. Phuket is one of 16 provinces included in the active DBD investigation. Koh Samui, within Surat Thani province, is also a high-activity market for foreign investment, though the principal enforcement concentration in 2026 targets Phuket, Bangkok, Chon Buri, and Chiang Mai.
Can a foreign shareholder hold 49% and still maintain effective control?
Meaningful influence over company decisions can be structured through preference shares carrying enhanced dividend rights or weighted voting on defined matters. However, exclusive operational control exercised by the foreign party while Thai shareholders remain passive is treated as a nominee indicator by regulators.
What does it cost to set up a legitimate company for buying a villa in Phuket?
Based on our estimates as of 2026, full incorporation with proper legal documentation runs approximately 80,000 to 200,000 THB, depending on structure complexity and the firm engaged. This figure does not include the capital contributions of the Thai shareholders themselves.
Is leasehold a safer alternative than a company structure?
Leasehold eliminates nominee risk entirely, but limits the investor's rights to a leasehold interest of up to 30 years with a renewal option. For investors with a shorter investment horizon or those unwilling to involve Thai co-shareholders, a lease arrangement is a structurally simpler solution.
What happens to the property after a nominee ruling?
The Department of Lands issues a forced-sale order with a 180-day deadline. If the property is not sold within that period, the land can be acquired by the state. Individuals involved also face separate criminal proceedings.
How should a foreign investor approach finding a credible Thai co-shareholder in Phuket or Koh Samui?
Based on our analytical observations, the most defensible arrangements involve Thai business people with a documented commercial and tax history demonstrating capacity to contribute the required capital. Law firms specialising in property transactions can assist with due diligence on potential partners. We consistently flag arrangements where the co-shareholder is introduced by the same intermediary selling the property, as this pattern frequently precedes nominee findings.
Does the company need to conduct operational business activity?
There is no formal statutory requirement, but a company that holds a single property and generates no revenue draws heightened regulatory attention. Conducting genuine business activity, such as residential or short-term letting, even at modest scale, measurably reduces the risk of the structure being classified as nominee.
