Buying property in Thailand can be an excellent investment, whether for personal use, retirement, or business. However, real estate transactions come with potential risks, including fraud, unclear ownership, hidden debts, and legal complications. This is where property due diligence becomes essential.
Property due diligence is the process of verifying legal ownership, title deeds, zoning laws, building permits, and financial liabilities before purchasing a property. It helps buyers avoid scams, legal disputes, and financial losses.
This guide covers everything you need to know about property due diligence in Thailand, including legal requirements, common risks, and best practices to ensure a safe and secure property purchase.
1. What is Property Due Diligence?
Property due diligence is an investigation process that confirms:
✔ The legal status of the property.
✔ The authenticity of the title deed.
✔ Whether the property has outstanding debts or encumbrances.
✔ That the property complies with zoning and building regulations.
💡 Why is it important?
Property fraud and disputes are common in Thailand. Due diligence helps prevent legal and financial risks before finalizing a transaction.
2. Key Areas of Property Due Diligence in Thailand
2.1 Title Deed Verification
The title deed (Chanote) is the most critical document in a property transaction. It proves ownership and land boundaries.
✔ Ensure the title deed is a Chanote (Nor Sor 4 Jor), which provides full ownership rights.
✔ Other types of title deeds, such as Nor Sor 3 Kor or Nor Sor 3, have restrictions.
✔ Verify that the title deed is genuine and legally issued.
✔ Confirm the land boundaries match the official survey records.
💡 Tip: Always check the original title deed at the Land Office and compare it with the seller’s copy.
2.2 Checking for Encumbrances (Mortgages & Liabilities)
A property may have existing mortgages, loans, court cases, or liens attached.
✔ Request a Title Search Report from the Land Office.
✔ Check for outstanding loans, mortgages, or unpaid property taxes.
✔ Verify if the property is subject to any court judgments or legal disputes.
💡 Tip: If a mortgage or encumbrance exists, the seller must clear the debt before the transfer.
2.3 Zoning and Land Use Regulations
Thailand has strict zoning laws that determine how land can be used.
✔ Check the property’s zoning designation (residential, commercial, agricultural, or industrial).
✔ Ensure the property can legally be used for your intended purpose.
✔ If buying a condominium, check the foreign ownership quota (foreigners can own only 49% of total units).
💡 Tip: Some areas prohibit high-rise buildings or foreign ownership. Always check local zoning laws.
2.4 Verifying the Seller’s Legal Authority
✔ Ensure the seller is the legal owner listed on the title deed.
✔ If the seller is a company, check the company’s legal registration and authority to sell.
✔ If buying from a developer, verify if they have the correct permits and licenses.
💡 Tip: Be cautious of third-party sellers or agents without proper authorization.
2.5 Reviewing the Sales and Purchase Agreement
The Sales and Purchase Agreement (SPA) should include:
✔ The full details of the property.
✔ The agreed price and payment terms.
✔ The responsibilities of both parties.
✔ Clauses covering penalties for breach of contract.
💡 Tip: Always have a lawyer review the contract before signing.
2.6 Environmental & Infrastructure Checks
✔ Ensure the property has access to roads, electricity, and water.
✔ Check for flood risks or environmental issues in the area.
✔ If buying near the coast, ensure compliance with coastal construction laws.
💡 Tip: Visit the property at different times of the day to assess noise levels, traffic, and surrounding conditions.
3. Due Diligence Process Step-by-Step
Step 1: Hire a Legal Expert
✔ Engage a real estate lawyer who specializes in Thai property law.
✔ Ensure they can conduct a full due diligence check.
Step 2: Verify the Title Deed at the Land Office
✔ Request a copy of the title deed from the seller.
✔ Cross-check it at the local Land Office for authenticity.
Step 3: Conduct a Title Search
✔ Verify ownership history.
✔ Check for outstanding mortgages, loans, or disputes.
Step 4: Review Zoning & Land Use Laws
✔ Ensure the land can be used for your intended purpose.
Step 5: Inspect the Property Physically
✔ Visit the property multiple times before making a decision.
✔ Look for signs of construction defects, land encroachments, or disputes.
Step 6: Review the Sales Agreement
✔ Ensure all details are accurate.
✔ Clarify who pays for taxes and transfer fees.
Step 7: Finalize the Purchase
