Before completing a Thai property purchase, buyers should verify the title deed type (a chanote, the highest and most secure form of Thai land title, is strongly preferred over lesser title types like Nor Sor 3 or Nor Sor 3 Kor, which carry more limited or unconfirmed boundary rights), confirm the seller's ownership and check for encumbrances/liens at the Land Department, and for condos, verify the building's foreign ownership quota has not been exceeded and that the condo juristic person (management company) has no outstanding debts or disputes. For any land-holding structure involving a Thai company, buyers should have an independent lawyer confirm the company is not an illegal nominee arrangement.
Thailand has multiple tiers of land title with meaningfully different levels of legal certainty — buying land under a weaker title type than a chanote is one of the most common and costly mistakes foreign buyers make.
Key Facts
Chanote (Nor Sor 4 Jor) is the strongest Thai land title, with GPS-surveyed and confirmed boundaries — always the preferred title type.
Nor Sor 3 and Nor Sor 3 Kor are lesser title types with less certain boundaries; land under these titles carries more legal risk and should be checked carefully before purchase.
The Land Department maintains records of encumbrances, mortgages, and liens against a title — always check these before purchase.
For condos, confirm the foreign ownership quota (49% cap) has not been exceeded in the specific building, and check the condo juristic person's financial health (outstanding common-area fee arrears can attach to the unit).
Thai company structures used to hold land on a foreigner's behalf must have genuine Thai shareholders with real economic interest — nominee arrangements are illegal under the Land Code and subject to enforcement.
Steps
Verify title deed type and boundaries — Confirm the property has a chanote title with clear, surveyed boundaries rather than a lesser title type.
Check Land Department records — Search for encumbrances, mortgages, or liens registered against the title before signing any purchase agreement.
Confirm the condo foreign quota and juristic person status — For condo purchases, verify with the juristic office that the foreign ownership cap is not exceeded and that there are no unresolved common-fee disputes.
Engage an independent property lawyer — Have a lawyer unconnected to the seller/developer/agent review title, contract terms, and (if applicable) company structure before completion.

Common Mistakes
Buying land under a Nor Sor 3 or weaker title without understanding the reduced legal certainty compared to a chanote.
Skipping an encumbrance check at the Land Department and later discovering an undisclosed mortgage or lien on the property.
Using an agent-recommended lawyer who is not truly independent of the seller or developer.
