Due diligence for buying land in Thailand through a company

For decades, foreign investors have followed a well-worn path to owning a piece of Thailand: set up a Thai company with 49% foreign shares and 51% held by “nominee” Thai shareholders, then have that company buy the land. It was an open secret, a grey-market solution that thousands of villas in Phuket, Koh Samui, and Chiang Mai were built upon.

But 2026 is not 2016. It’s not even 2023.

The Thai government has launched what can only be described as a full-scale assault on nominee structures. With AI-powered database integration, multi-agency task forces, and criminal prosecutions accelerating, the question “How do I set up a company to buy land?” has been replaced by a more urgent one: “If I already have—or am considering—this structure, what due diligence do I need to survive the crackdown?”

This guide answers that question with the latest 2026 enforcement realities, legal requirements, and—crucially—the warning that for many investors, the company route is no longer a viable option.

Part 1: The 2026 Enforcement Landscape – Why Due Diligence Is No Longer Optional

Before diving into checklists and procedures, you must understand what’s happening in Thailand right now. The rules haven’t just changed—the enforcement machinery has been fundamentally upgraded.

The “Big Data” Dragnet

The Department of Business Development (DBD) has integrated its databases with the Revenue Department and the Land Office. This isn’t bureaucratic theory—it’s operational reality in 2026. This integration allows authorities to instantly flag companies that fit nominee profiles .

What triggers an investigation? The system now looks for:

• Zero Staff, Zero Revenue: Companies that own luxury villas but file tax returns showing no business activity, no employees, and no income
• Wealthy Nominees: Thai shareholders who, on paper, invested millions of baht but have no tax history or visible income source to support such wealth
• Foreign Control Patterns: Companies where a foreigner is the sole director with signing authority, while majority shareholders have signed undated share transfer forms

The Numbers Tell the Story

The scale of enforcement is staggering:

• 46,918 companies across seven provinces targeted for inspection (Chiang Mai, Chon Buri, Phuket, Krabi, Surat Thani, Prachuap Khiri Khan, Bangkok)
• Over 110,000 companies with foreign investments under investigation as of February 2026
• 852 companies prosecuted for nominee-related offenses between 2025-2026, with estimated economic damages exceeding THB 15.1 billion
• 21,459 companies already identified in initial investigations as potentially using Thai nominees to hold shares in land or real estate companies

The Phuket operation alone resulted in 231 arrests, including 98 foreign suspects and 37 Thai nationals acting as nominee agents. Assets seized exceeded THB 1.5 billion, with 245 land documents confiscated .

What This Means for You

If you’re considering the company route, you’re not just taking a legal risk—you’re entering a system actively designed to detect and prosecute your structure. The penalties are no longer theoretical: up to three years imprisonment, fines of 100,000 to 1 million baht, forced land sale within 180 days, and permanent blacklisting from Thailand .

Due diligence in this environment isn’t about checking boxes. It’s about determining whether your entire investment thesis is viable.

Part 2: The Legal Framework – Understanding What “Compliant” Actually Means

To conduct proper due diligence, you must first understand what Thai law actually permits—and prohibits.

The Core Restriction: When Is a Company “Foreign”?

Under Sections 97 and 98 of the Land Code, a company is classified as “foreign” (and thus restricted from land ownership) if:

1. Foreign shareholders hold more than 49% of the company’s registered capital; OR
2. More than half of the total number of shareholders are foreigners

If your company meets either criterion, it is legally foreign and cannot own land in Thailand. Period.

What About Control vs. Ownership?

Here’s where the 2026 enforcement gets sophisticated. Authorities no longer look仅仅 at the share register. They examine the full chain of shareholding and the reality of control .

The Land Department’s guidelines direct officers to investigate:

• Foreigners who are authorized signatories
• Foreign nationals listed as company promoters
• Foreigners holding preferred shares with superior voting rights
• Thai shareholders partnered with lawyers or brokers—potentially serving as nominees

Crucially, officers must verify the income of Thai shareholders and the source of funds they used to pay for shares. If a Thai shareholder with minimal income supposedly invested millions, that’s an immediate red flag .

The “Effective Control” Doctrine

The Cabinet has approved in principle amendments to the Foreign Business Act that would redefine “Thai company” based on effective control, not merely share percentages. This means nominee arrangements are legally invalid regardless of paper shareholding .

Part 3: The Due Diligence Checklist – What to Verify Before Buying Land Through a Company

If you’re proceeding with a company structure—and after reading this far, you should be questioning that decision—here’s the comprehensive due diligence required in 2026.

Phase 1: Company Structure and Shareholder Verification

1. Shareholding Ratio Audit

First, verify the basic numbers. Foreign shareholders must hold no more than 49% of registered capital. But don’t stop there. Count the number of foreign shareholders—if more than half of all shareholders are foreign, the company is disqualified regardless of capital percentage .

2. Thai Shareholder Background Investigation

This is where most nominee structures fail in 2026. For each Thai shareholder, you must verify:

• Occupation and monthly income with supporting evidence (tax returns, employment letters, bank statements)
• Source of funds used to purchase shares. Did this individual actually have the money, or was it provided by the foreign investor?
• Relationship to foreign investor—are they a friend, employee, or professional nominee?
• Involvement in multiple nominee companies—authorities now track individuals appearing across multiple “shelf” companies

3. Share Transfer Restrictions

Review the company’s articles and any shareholder agreements. Are there undated share transfer forms? Blank transfer documents signed by Thai shareholders? These are evidence of nominee arrangements .

4. Director Authority Review

Who has signing authority? If the foreigner is the sole director with full control while Thai shareholders have no management role, this structural red flag will be noted .

Phase 2: Financial Due Diligence

1. Company Financial History

Authorities scrutinize companies that own valuable real estate but show no business activity. Your due diligence must include:

• Tax filings for past 3-5 years—does the company report revenue, employees, or business operations?
• Expense patterns—who pays for property maintenance, utilities, and taxes?
• Dividend distributions—if profits exist, do they flow proportionally to shareholders?

2. Source of Funds for Land Purchase

When the company buys land, the source of purchase funds will be investigated. You need:

• Full paper trail for all funds used—bank transfers, SWIFT records, currency exchange documents
• Explanation of any gap between registered capital and purchase price (loans must be properly documented)

3. Ongoing Financial Compliance

If the company has no legitimate business, how will it justify its existence year after year? Recurring losses with no business activity invite scrutiny .

Phase 3: Land Title and Physical Due Diligence

1. Title Deed Verification (Chanote)

Never rely on copies. You must:

• Verify the Nor Sor 4 Jor (Chanote) title at the local Land Office
• Check for encumbrances—mortgages, servitudes, usufructs, leases
• Confirm boundaries match physical inspection—discrepancies are common

2. Zoning and Land-Use Compliance

Even with clean title, the land may not be usable for your intended purpose:

• Verify zoning regulations with the local administrative office
• Check building control rules—height limits, set-back requirements
• Determine if Environmental Impact Assessment (EIA) is required for your planned development

3. Physical Inspection

Don’t skip the site visit. Look for:

• Encroachment by neighbors
• Utility access (or lack thereof)
• Flood risk (check with locals, not just sellers)
• Soil quality if planning construction

Phase 4: Regulatory Compliance Verification

1. Foreign Business Act Compliance

If your company engages in any business activity beyond holding land, verify it doesn’t violate the Foreign Business Act’s prohibited or restricted categories .

2. BOI or IEAT Status (If Applicable)

If you’re relying on BOI promotion or IEAT园区 status to own land:

• Verify the certificate is valid and conditions are met
• Understand post-operation requirements—BOI land must be sold within 1 year if business ceases
• Confirm your business activity qualifies under current regulations

3. Anti-Money Laundering Considerations

Nominee arrangements are increasingly treated as money laundering predicate offenses. Pending amendments would allow AMLO to seize assets linked to illegal transactions .

Part 4: The Alternatives – Legal Ways to Own Property in Thailand

Given the 2026 enforcement environment, every investor should consider whether legal alternatives exist. They do—and they’re worth exploring before committing to a high-risk nominee structure.

Option 1: Foreign Freehold Condominium

For many investors, this is the simplest solution. Foreigners can own condominium units freehold, provided:

• The building’s foreign quota (49% of total space) is not exceeded
• Funds are transferred from overseas in foreign currency

The THB 3 million threshold has become significant—this level of condo investment can now support certain visa pathways .

Option 2: Long-Term Leasehold

Leases of up to 30 years are legally protected under Thai law. While not ownership, a well-structured lease with renewal options provides security of tenure. For many, this is preferable to the existential risk of nominee prosecution .

Option 3: BOI-Promoted Company

If your business qualifies for BOI promotion, your Thai company can be 100% foreign-owned and can own land for the promoted activity . This is fully legal and carries none of the nominee risks.

Requirements vary by industry, but typically include minimum investment thresholds (often THB 1-10 million depending on sector) and employment of Thai staff .

Option 4: IEAT Industrial Estate

For industrial investments, purchasing land in an IEAT-certified industrial estate allows foreign-owned companies to own land . As of September 2025, 67 such estates were certified .

Option 5: The THB 3 Million Investment Visa Pathway

Several law firms now promote “visa-included” property packages where a THB 3+ million condo purchase can support long-term stay applications . While not a direct land ownership solution, this pathway offers legal residency without nominee risks.

Part 5: Red Flags – When to Walk Away

Some situations are too dangerous to touch. Here are red flags that should trigger immediate rejection:

The “We Handle Everything” Agent

If an agent or lawyer promises to “take care of everything” with nominee Thai shareholders, and discourages you from meeting them or understanding the structure, run. You’re being set up for a fall .

Pre-Signed Share Transfer Forms

If Thai shareholders are asked to sign undated share transfer forms, this is explicit evidence of nominee arrangement. In a 2026 enforcement action, these documents are prosecution exhibits .

Shareholders with Implausible Wealth

A taxi driver, housekeeper, or village farmer supposedly investing millions in your company is an instant red flag that will trigger investigation .

No Business Activity

A company with no employees, no revenue, and no operations—but owning a luxury villa—is precisely what the DBD’s algorithms are designed to flag .

Cash Transactions

Any land purchase involving significant cash without full banking trail is impossible to defend. Authorities will assume illegal nominee structure .

Part 6: The Penalties – What Happens If You’re Caught

Understanding the consequences is essential for risk assessment.

Criminal Penalties Under Land Code

Additional Consequences

Beyond the penalties above, convicted foreigners face:

• Deportation and permanent blacklisting from Thailand
• Forced disposal of land within 180 days to 1 year (no compensation if deadline missed)
• Forfeiture of all money paid for the land
• Asset seizure under pending AMLO amendments

Thai nominees face equally serious consequences: imprisonment, criminal records, and potential money laundering charges .

Real Cases, Real Consequences

Phuket, September 2024: Twenty-three defendants (including Thai nationals, foreigners, and corporate entities) convicted for orchestrating nominee arrangements for approximately 60 companies. Sentences: initial 10 years imprisonment (reduced to 5 on cooperation), THB 200,000 fines, companies ordered dissolved .

Koh Samui, 2024: Following the death of a French businesswoman, investigation revealed her companies used Thai nominees to own a THB 50 million villa. Assets ordered forcibly sold, demonstrating that enforcement continues even posthumously .

Chachoengsao, 2024: 1,500 rai of forest land seized from Thai company acting as nominee for Chinese investors. Land had been converted to durian plantations—now forfeited .

Part 7: Professional Support – Who You Need on Your Team

If you proceed with due diligence, you need the right professionals. But choose carefully.

What Your Lawyer Should Do

A competent lawyer for 2026 should:

• Conduct full shareholder background investigations, not just collect passport copies
• Verify source of funds for all Thai shareholders
• Review company financial history for red flags
• Physically inspect title deeds at the Land Office
• Advise on legitimate alternatives, not just push the company route

Warning Signs in Professional Advisors

Be extremely cautious if your lawyer or agent:

• Dismisses 2026 enforcement as “just a formality”
• Offers nominee shareholders as a “standard package”
• Discourages you from meeting Thai shareholders
• Cannot explain how the structure survives DBD scrutiny

The Compliance-First Approach

The most reputable firms now advise clients to:

1. Rent first—understand the area and your needs before committing
2. Explore legal alternatives—condo freehold, leasehold, BOI
3. If company is necessary, ensure it has genuine business activity, not just passive land holding
4. Document everything—funds flow, shareholder relationships, business purpose

Part 8: Practical Steps – Your Due Diligence Action Plan

If you’re moving forward, here’s a step-by-step approach:

Step 1: Engage Independent Legal Counsel

Not the lawyer recommended by the seller or agent. You need someone whose only client is you. Verify they are licensed in Thailand and have experience with 2026 enforcement realities .

Step 2: Conduct Initial Company Structure Review

Before any payment, your lawyer should:

• Review proposed shareholding structure against Land Code requirements
• Investigate proposed Thai shareholders (income verification, source of funds)
• Assess whether structure triggers DBD red flags

Step 3: Title and Land Due Diligence

• Obtain certified copy of title deed from Land Office
• Verify boundaries and encumbrances
• Check zoning and land-use restrictions
• Physical inspection of property

Step 4: Financial Verification

• Trace source of all funds for purchase
• Document overseas transfers with FET forms (Foreign Exchange Transaction forms)
• Plan for ongoing company compliance (tax filings, accounting)

Step 5: Contract and Transfer Preparation

• Draft SPA with clear conditions precedent (including due diligence completion)
• Verify tax and fee responsibilities
• Plan transfer date with Land Office appointment

Step 6: Post-Purchase Compliance

• Maintain proper corporate records
• File annual tax returns (even with minimal activity)
• Document any business purpose
• Keep shareholder information current

Conclusion: The 2026 Reality Check

The question “Is it safe to set up a Thai company to buy land in 2026?” has a clear answer from every authoritative source: No, it is not safe—unless the company has genuine business activity, real revenue, and legitimate Thai shareholders with provable wealth .

For the typical foreign investor wanting a holiday villa, the nominee company structure is a ticking time bomb. The Thai government has made its intentions clear: tens of thousands of companies are under investigation, prosecutions are accelerating, and penalties include imprisonment and forced asset sale.

The alternatives—condo freehold, long-term leasehold, BOI promotion, IEAT园区—offer legal, secure pathways without the existential risk of criminal prosecution. They may require different investment structures or location choices, but they also offer something the nominee route cannot: peace of mind.

The bottom line for 2026: If you’re considering buying land through a Thai company, do not proceed without exhaustive due diligence—and even then, seriously question whether the investment is worth the risk. The era of the nominee company is ending. Don’t let your dream home become a legal nightmare.
