Investing in real estate in Thailand can be a lucrative opportunity, whether for residential, commercial, or investment purposes. However, property fraud, legal disputes, and unclear ownership titles can pose significant risks. Conducting property due diligence is crucial to verify ownership, ensure legal compliance, and avoid future legal complications.
This guide provides a comprehensive overview of property due diligence in Thailand, including legal procedures, key documents, risks, and expert recommendations for safe property investments.
1. What is Property Due Diligence?
Property due diligence is the process of verifying all legal, financial, and physical aspects of a property before purchasing. It helps investors identify potential risks such as:
✔ Fake ownership claims
✔ Land encroachment disputes
✔ Unpaid mortgages or taxes
✔ Zoning and land-use restrictions
✔ Illegal construction
By conducting due diligence, buyers can make informed decisions and protect their investments.
2. Legal Framework for Property Ownership in Thailand
Thailand’s property laws are governed by the Land Code Act, Civil and Commercial Code, Condominium Act, and Foreign Business Act. Understanding these laws is essential for both Thai and foreign investors.
2.1 Property Ownership for Thai Nationals
Thai citizens can freely own land, houses, condominiums, and commercial properties without restrictions.
2.2 Property Ownership for Foreigners
Foreigners cannot directly own land but can acquire property through:
✔ Leasehold Agreements – Up to 30 years with a renewal option.
✔ Condominium Ownership – Foreigners can own up to 49% of the total condo units.
✔ Thai Company Ownership – Foreigners can own land through a Thai-registered company (51% Thai-owned).
✔ Investment Promotion (BOI) – Special exemptions for high-value investors.
Due diligence ensures that these ownership structures comply with Thai law.
3. Key Aspects of Property Due Diligence
3.1 Verifying Land Title Deeds
The most important step in property due diligence is checking the title deed (Chanote) to confirm legal ownership and property rights.
Types of Land Title Deeds in Thailand
| Title Deed | Ownership Rights | Transferability | Best for Investment? |
|---|---|---|---|
| Chanote (Nor Sor 4 Jor) | Full ownership | Yes | ✅ Best option |
| Nor Sor 3 Gor | Ownership with clear boundaries | Yes | ✅ Good |
| Nor Sor 3 | Ownership but no precise survey | Yes (requires formalization) | ❌ Risky |
| Sor Kor 1, Por Bor Tor 5, Nor Sor 2 | No legal ownership | No | ❌ Not recommended |
✔ Always invest in Chanote or Nor Sor 3 Gor land for secure ownership.
3.2 Checking Land Encumbrances and Liabilities
The property may have legal obligations such as mortgages, loans, or disputes. Buyers should request a title deed search from the Land Department to check for:
- Mortgages or Liens – Outstanding debts secured against the property.
- Court Disputes – Ongoing lawsuits or claims over the property.
- Lease Agreements – Existing tenants or rental contracts affecting ownership rights.
✔ Ensure the property has a clear title before purchase.
3.3 Land Use and Zoning Regulations
Each province in Thailand has zoning laws that regulate land use, construction, and environmental protection. Buyers must check:
✔ Building restrictions – Some areas prohibit high-rise buildings.
✔ Commercial vs. Residential zones – Certain zones restrict business operations.
✔ Environmental laws – Coastal or forested areas may have land use limitations.
❌ Ignoring zoning laws can lead to fines, demolition orders, or legal disputes.
3.4 Verifying Building Permits and Construction Approvals
If purchasing a house, villa, or commercial property, confirm:
✔ Building Permit – Ensures the structure was legally approved.
✔ House Registration Book (Tabien Baan) – Confirms official residence status.
✔ Environmental Impact Assessments (EIA) – Required for large developments.
Warning: Some properties are built without permits, leading to potential demolition orders from local authorities.
3.5 Reviewing Sale and Purchase Agreements
The Sale and Purchase Agreement (SPA) is a legally binding contract that outlines:
✔ Agreed purchase price and deposit amount.
✔ Property details and ownership structure.
✔ Transfer date and conditions.
✔ Penalties for breach of contract.
Buyers should consult a real estate lawyer to review the contract before signing.
3.6 Checking Developer and Seller Background
If buying from a developer, check:
✔ Company registration and reputation.
✔ Past projects and customer reviews.
✔ Construction timeline and project licenses.
❌ Avoid dealing with unlicensed developers or fake property sellers.
3.7 Tax and Fee Assessment
Property transactions in Thailand involve various taxes and fees, including:
| Tax / Fee | Who Pays? | Rate |
|---|---|---|
| Transfer Fee | Buyer | 2% of appraised value |
| Specific Business Tax (SBT) | Seller | 3.3% if owned for <5 years |
| Stamp Duty | Seller | 0.5% (if SBT not applicable) |
| Withholding Tax | Seller | 1% of sale price (individual) or 20% (company) |
✔ Ensure tax compliance to avoid legal penalties.
3.8 Conducting Physical Property Inspections
Apart from legal due diligence, buyers should inspect the property for:
✔ Structural defects or water damage.
✔ Unauthorized modifications or illegal extensions.
✔ Access to roads, utilities, and drainage systems.
A professional property surveyor can provide a detailed inspection report.
