Property Due Diligence Process in Thailand

Verifying Title Deeds & Ownership

Accurate title verification is the foundation of secure property due diligence in Thailand.

The main title deed types are:

  • Chanote (Nor Sor 4 Jor): offers full private ownership and clear boundaries
  • Nor Sor 3 Gor: land legally surveyed but not fully titled
  • Nor Sor 3: older documents, boundaries may be unclear

Request the original deed for inspection at the local Land Office.

Check that:

  • The seller matches the registered owner
  • Title boundaries align with the physical site (use a land surveyor if needed)
  • There are no undisclosed mortgages, leases, or disputes registered

Always collect and scrutinize:

  • Sale and purchase agreement
  • Tabien Baan (house registration book)
  • Government-issued tax receipts
  • Building permits and plans
  • Corporate documents if a company is the seller

Verify at the Land Office for:

  • Registered mortgages or liens
  • Ongoing litigation or bankruptcy involving the seller

Missing or invalid documents may stall transfer or expose you to hidden liabilities.
