Thailand’s real estate sector remains a major recipient for global investment, attracting a diverse spectrum of foreign buyers seeking a home in the country or purchasing investment assets. However, buying property in Thailand is characterised by complex regulatory requirements that buyers must comply with to prevent penalties or litigation. This is particularly important for foreigners who must also navigate Thailand’s restrictions on foreign property buyers.
This article provides a summary of what foreign property buyers need to know about purchasing property in Thailand, particularly on the importance of due diligence, ongoing compliance requirements, and the importance of having a Sale and Purchase Agreement (SPA) when conducting property transactions.
Property Ownership Constraints on Foreigners
Property ownership in Thailand is regulated principally by the Civil and Commercial Code (CCC), the Land Code, and, where relevant, the Condominium Act. Additional regulations, such as zoning requirements, building control rules, and environmental legislation, apply depending on the characteristics of the property and its intended use.
A primary consideration for foreign purchasers is the statutory restriction on land ownership under the Land Code. While direct freehold title to land remains prohibited for foreign individuals, specific sanctioned mechanisms exist to facilitate investment:
- Long-term Leases and Superficies: Under the CCC, foreign nationals may register leases for a maximum duration of 30 years. Superficies rights further allow a party to own structures upon the land, providing a legal separation between land and building ownership.
- Condominium Ownership: Governed by the Condominium Act, foreign nationals may hold freehold title to units provided that the total foreign ownership within the building does not exceed the mandatory 49% quota.
- Investment Exemptions: Limited exceptions are available for projects promoted by the Board of Investment (BOI) and land located within designated industrial estates.
Similar restrictions apply to entities classified as “foreign” under the Foreign Business Act, unless a specific exemption or approval is provided. Before starting negotiations, prospective buyers must assess whether their intended ownership structure is legally permissible and whether additional approvals or filings will be required.
The Function and Structure of the Sale and Purchase Agreement
The SPA serves as the principal contractual instrument governing the parties’ obligations prior to ownership transfer. Under Thai law, ownership of land, buildings, and condominium units does not pass upon execution of the SPA; rather, ownership transfers only upon formal registration of the transaction at the Land Department. An SPA therefore operates as a guideline for parties that leads towards successful registration and provides contractual protection should the transaction fail to proceed.
A well-structured SPA generally includes the following elements:
- Property Identification: A detailed description consistent with official records, specifying the type of title deed, land area, boundaries, and associated rights.
- Payment Terms and Pre-completion Conditions: Definitive pricing, deposit schedules, and conditions precedent such as successful due diligence or confirmation of the foreign ownership quota.
- Seller Representations and Warranties: Confirmation that the seller holds valid and marketable title, that the property is free from registered encumbrances (mortgages, servitudes, or usufructs), and that no undisclosed liabilities affect the asset.
- Closing Costs: Clear allocation of responsibility for taxes and transfer fees payable at the Land Department to prevent disputes during registration.
Conducting Comprehensive Due Diligence
Due diligence is a fundamental element of property transactions in Thailand and serves as a primary safeguard against regulatory, financial, and operational risks. The process involves a technical review of the following:
Verification of Title Deed and Encumbrances
Buyers should verify the authenticity of the title deed at the relevant Land Office. While Chanote (Nor Sor 4 Jor) titles provide the highest degree of legal certainty, other forms of title require rigorous examination to confirm boundary accuracy and the extent of the owner’s rights. This includes checking for any registered leases or mortgages that may restrict future use.
Zoning and Land-Use Compliance
Zoning regulations govern permissible uses, construction density, and building height limits. Failure to verify these requirements before entering into an SPA can affect project viability. Furthermore, certain developments may necessitate an Environmental Impact Assessment (EIA) approval before construction can proceed.
Off-Plan and Pre-Construction Considerations
For off-plan acquisitions, buyers must ensure the developer has obtained all requisite building permits. Reviewing the developer’s financial standing and compliance history helps assess the likelihood that the development will be completed in accordance with publicly disclosed specifications.
Share Acquisitions
Where a transaction involves acquiring shares in a property-holding company, a broader audit is necessary. This includes examining financial statements and corporate governance documents to confirm the absence of unlawful nominee arrangements.
The 2026 Regulatory Environment: Enhanced Scrutiny
As of 1 January 2026, the Department of Business Development (DBD) has implemented tighter verification protocols that impact foreign buyers utilizing corporate structures:
- Shareholder Verification: Thai shareholders in companies with foreign interests must now provide documented evidence of genuine investment funds, including three months of bank statements and transaction records matching the share subscription.
- Address Registration: Head office addresses are now verified against the national civil registration database. Additional documentation, including owner consent, is required if five or more entities are registered at a single address.
For rental investments, the Residential Lease Notification B.E. 2568 (2025) provides mandatory protections for tenants in consumer lease arrangements, regulating security deposit returns and utility charges.
Risk Management and Statutory Compliance
Risks frequently arise where parties rely on informal commitments or where due diligence is neglected. Issues such as boundary inconsistencies and unregistered encumbrances can significantly delay the transfer process. Buyers are advised that verbal assurances regarding renovations or fixtures are enforceable only when expressly incorporated into the SPA.
Foreign purchasers must strictly avoid the use of nominee ownership structures. Although sometimes marketed as a means of circumventing statutory restrictions, such arrangements contravene the Land Code and the Foreign Business Act. They carry material enforcement risks, including the forced disposal of the property, administrative penalties, and potential criminal liability for all involved parties.
Preparing for a Smooth Property Purchase
A successful transaction requires early preparation and a clear understanding of the applicable legal framework. Buyers should ensure title information is accurate, that zoning rules permit the intended use, and that they are aware of all tax obligations arising from the transfer.
While Thailand offers a wide range of opportunities, property transactions must be undertaken with careful consideration of procedural requirements. A practical understanding of ownership structures and the function of SPAs enables buyers to protect their interests and ensure the transfer proceeds in accordance with Thai law.
