Official Thailand property and transaction resources

By Thailand Expat Services Last reviewed: 9/10/2025

An authority-first directory for Land Office, tax, BOI, consumer and provider-identity checks.

Use official sources for law, registration, tax and authority procedures. A link's availability does not establish that it applies to a particular transaction.

Department of Lands

  • Department of Lands — use the current authority site and the relevant Land Office to obtain the record, registration procedure and calculation applicable on the transaction date. Previously linked English PDFs failed the rollout-day availability check and are not relied on here.
  • Contact the competent local Land Office for the actual property and instrument.

Revenue and local tax

Provider identity

  • For a company involved in a transaction, obtain a current Department of Business Development record through an accessible official channel. Registration does not certify property competence, licensing, advice, solvency or suitability.

Commercial listing portals are advertising and search tools, not official registers. Inclusion is not endorsement. Confirm provider identity, profession-specific credentials, scope, insurance and written engagement independently.
