How do I check if a property title deed is genuine in Thailand?

Property title deed verification in Thailand: **Title deed types (strongest to weakest):** 1. **Chanote (Nor Sor 4 Jor):** Full ownership with GPS-surveyed boundaries — the gold standard 2. **Nor Sor 3 Gor:** Certificate of use with approximate boundaries, upgradeable to Chanote 3. **Nor Sor 3:** Certificate of use, less precise boundaries 4. **Sor Kor 1:** Possession certificate — weakest, not recommended for purchase **Verification steps:** 1. Request title search at the Land Office (free) 2. Check the registered owner matches the seller 3. Verify boundaries with physical survey 4. Check for encumbrances: mortgages, liens, easements, leases, court orders 5. Confirm no pending legal disputes 6. Verify land is not in a reserved zone (forest, military, etc.) **Red flags:** Seller can't produce original title deed, price significantly below market, rushed transaction, intermediaries insisting on cash payment. Always hire a lawyer for due diligence.
