Due Diligence in Thailand

Due diligence in Thailand refers to the systematic investigation and verification of legal, financial, operational, and technical information before entering into a significant transaction. This process is especially critical for foreign investors, buyers of real estate, and parties involved in mergers, acquisitions, or joint ventures. Failure to conduct adequate due diligence can result in substantial financial loss, legal exposure, or acquisition of encumbered or unlawfully held assets.

This article provides an in-depth legal overview of due diligence procedures in Thailand, focusing primarily on property transactions and corporate acquisition scenarios. It outlines what needs to be checked, where the information is sourced, and the implications of findings from a Thai legal and regulatory perspective.

I. Legal Foundation and Importance

Due diligence is not codified as a standalone requirement under Thai law. However, its practice is deeply rooted in contract law principles under the Thai Civil and Commercial Code. Under this framework, parties to a transaction are presumed to act in good faith and are responsible for conducting reasonable verification of representations made by the other party. A buyer who fails to discover encumbrances or defects that would have been evident through proper diligence may not be entitled to legal remedies later.

For foreign nationals, due diligence is doubly important due to language barriers, unfamiliarity with Thai administrative processes, and the limited enforceability of certain oral representations.

II. Real Estate Due Diligence

A. Title Verification

The most fundamental step is verifying the title deed (Chanote) or similar land document, such as Nor Sor 3 Gor or Nor Sor 3 Kor. The Thai Land Code governs the classification and hierarchy of title documents, and not all confer the right to build or sell.

A qualified Thai lawyer will perform a title search at the provincial or district Land Office, reviewing:

• The chain of title ownership

• Land size and boundaries

• Encumbrances or mortgages

• Servitudes, usufructs, or superficies

• Land use restrictions or zoning issues

The official land records are maintained in Thai and are manually updated, so careful attention is needed during transcription and interpretation.

B. Seller and Developer Due Diligence

The due diligence must also confirm that:

• The seller is the registered owner or authorized legal representative

• The seller or developer is not involved in ongoing litigation or bankruptcy

• The developer holds proper licenses to subdivide, construct, or sell (e.g., EIA approval, building permit)

This is often overlooked in condominium purchases, where the unit is ready for sale but the building lacks necessary environmental or structural approvals, rendering the transfer potentially void.

C. Physical and Environmental Inspections

Legal advisors often conduct on-site inspections to confirm:

• The property physically matches its legal description

• There is direct road access (as per zoning)

• No squatters or unauthorized occupants are present

• There is compliance with local zoning laws and building codes

In certain areas, environmental restrictions—such as those in marine parks or conservation zones—may completely prohibit development even on titled land.

III. Corporate Due Diligence

When acquiring a Thai company, conducting a multi-layered review is essential. Thai companies are governed by the Civil and Commercial Code (private limited companies) or the Public Company Act B.E. 2535 (for public companies).

A. Corporate Records

A legal review typically involves examination of:

• Company registration documents from the Department of Business Development (DBD):

  • Memorandum of Association

  • Articles of Association

  • List of shareholders (updated)

  • Director appointments and authorities

• Capitalization and issued shares

• Board resolutions and meeting minutes

• Any amendments to objectives or structure

If foreign ownership is involved, the legal structure must be reviewed for compliance with the Foreign Business Act B.E. 2542, which limits foreign participation in certain sectors.

B. Financial and Tax Status

A buyer must verify:

• Audited financial statements (past 3 years)

• Outstanding tax liabilities (through the Revenue Department)

• VAT and corporate tax registration

• Records of any tax audits, assessments, or fines

A certified public accountant (CPA) may assist in reconciling discrepancies in asset declarations, working capital, and income reporting. Buyers should also investigate transfer pricing issues, especially in cross-border transactions.

C. Labor and Compliance

Due diligence must extend to:

• Review of employee contracts and benefits

• Outstanding labor disputes or Social Security Fund contributions

• Compliance with labor laws such as the Labor Protection Act B.E. 2541

Foreign employees must be properly documented, and all work permits and visa records should be up to date.

IV. Regulatory and Licensing Checks

For regulated businesses such as those in hospitality, logistics, education, and food production, due diligence should include:

• Verification of business licenses

• BOI privileges (if applicable) and their current standing

• EIA reports, FDA approvals, or other industry-specific licenses

• Environmental Impact Assessment compliance (mandatory for many developments)

Foreign buyers should also determine if the target company holds licenses that are non-transferable or will be revoked upon shareholding changes.

V. Litigation and Liabilities

A litigation check includes:

• Search of civil, criminal, and administrative court databases

• Pending or past lawsuits involving the company or property

• Regulatory violations or sanctions

• Bankruptcy or rehabilitation proceedings

Thailand does not have a centralized litigation repository, so separate court and enforcement division visits may be necessary depending on jurisdiction.

VI. Contractual Review and Contingency Planning

Legal due diligence should culminate in a summary report that flags:

• High-risk findings

• Legal gaps or missing documentation

• Non-compliance with Thai laws

• Potential regulatory delays or risks

This allows the buyer to insert protective clauses into the contract, such as:

• Warranties and representations

• Conditions precedent (e.g., building permit approval)

• Indemnification clauses

• Post-closing obligations

If significant liabilities are discovered, a price adjustment or escrow arrangement may be negotiated.

VII. Special Considerations for Foreign Buyers

Foreign nationals and companies must remain aware of the following:

• Thai land ownership by foreigners is severely restricted, and schemes using nominee shareholders are illegal

• Long-term leasehold, superficies, or joint venture ownership models must be carefully structured

• Use of a Thai holding company must be transparent and compliant with the Foreign Business Act

Improper structuring could result in post-acquisition revocation of land rights or business licenses.

Conclusion

Due diligence in Thailand is a multi-disciplinary and multi-agency process that cannot be overlooked. Whether acquiring a property, business, or development project, the buyer assumes significant legal risk without adequate verification.

Because Thai law imposes the burden of discovery on the buyer, it is imperative to engage a licensed Thai attorney—ideally with cross-border experience and access to official registries, land offices, and government agencies. Proper due diligence not only safeguards the investment but also ensures long-term legal stability and peace of mind.
