To verify the legality of a real estate contract in Thailand, start by checking the title deed (Chanote) at the local Land Department, ensure there are no encumbrances or mortgages, and have the contract reviewed by a licensed Thai lawyer. This step is essential before making any payments.
Why Contract Verification is Essential in Thailand
Thai law imposes strict restrictions on land ownership by foreigners. A poorly drafted contract or one based on an invalid title can lead to the nullification of the transaction, loss of any payments made, or even legal action. Therefore, vigilance is crucial, regardless of your nationality.
⚠️ Warning
In Thailand, foreigners generally cannot own land outright. However, they can purchase an apartment in a condominium (within the limit of 49% of the building reserved for foreigners) or use specific legal structures for houses and villas. A contract that circumvents this rule may be illegal.
Step 1: Verify the Title Deed at the Land Department
The most secure land title in Thailand is the Chanote (Nor Sor 4 Jor). It corresponds to an official cadastral record and grants the most comprehensive rights. Other titles exist (Nor Sor 3 Gor, Sor Kor 1…) but offer fewer guarantees.
- Visit the Land Department of the relevant province (or its district office, the Land Office).
- Request to view the official register using the parcel number indicated on the title.
- Verify the seller's identity: their name must exactly match the registered title.
- Check for the absence of mortgages, easements, seizures, or ongoing disputes.
💡 Good to Know
The Thai Land Department (Krom Thi Din) has a centralized registration system. Any legal encumbrance must be recorded there to be enforceable against third parties. If it is not listed, it cannot legally affect you as a bona fide buyer.
Step 2: Analyze the Contract Content
A valid real estate sales contract in Thailand must include:
- The full identity of both parties (seller and buyer)
- A precise description of the property and its title number
- The sale price, payment terms, and deadlines
- Any suspensive conditions (financing, permits…)
- Penalties in case of default by either party
- The date and location of the property transfer at the Land Department
The contract is typically drafted in Thai. Always request a bilingual version and have it reviewed by an independent lawyer — not one recommended by the real estate agent or developer.
Step 3: Consult an Independent Local Lawyer
This is the most important step. A licensed Thai lawyer (Barrister or Solicitor registered with the Thai Bar Association) can:
- Verify the legality of the proposed legal structure (direct purchase, long-term lease, Thai company…)
- Identify any abusive clauses or those contrary to Thai law
- Confirm that the foreign quota of the condominium is not exceeded
- Assist you on the day of the transfer at the Land Department

Youssef, a Moroccan investor based in Bangkok, and Marie-Eve, a Quebecer purchasing an apartment in Chiang Mai, both avoided costly disputes by consulting a local lawyer before signing the preliminary contract. The cost of this consultation is negligible compared to the financial risk involved.
