How to find who owns a piece of land in Thailand
There are four realistic ways to find out who owns a parcel in Thailand. They differ in time, cost and what you need to start. Here is an honest comparison, including when the land office is the right choice.

One fact shapes every option: owner names are personal data, so the Department of Lands (DOL) does not publish them online. Government map services show parcel details, but not who owns the land.
1. Ask at the local land office
The provincial or branch land office (สำนักงานที่ดิน) holds the actual register. The current holder is recorded in the registration entries (สารบัญจดทะเบียน) on the office copy of the deed. To inspect it or request a copy you will generally need:
- The deed number and the district it is registered in (see where to find the deed number).
- A stated reason or legitimate interest, such as being a party to a contract, an adjoining owner or in a dispute. Officers decide case by case.
- ID, a trip to the right office during office hours, and a modest official fee.
It is the most reliable source, but you need the deed number first and a reason the officer accepts.
2. LandsMaps and DOL apps
LandsMaps is the DOL's free parcel map (web and app). Tap a parcel or search by deed number to see the deed number, land number, survey page, map sheet, area, location and the Treasury appraisal (see the 2570 appraisal round). It does not show the owner. It is a good first step for finding the deed number from a map location.
3. Ask neighbours and local officials
Neighbours, the village head (ผู้ใหญ่บ้าน) and "for sale" or "for rent" signs often lead to the owner or a caretaker. The sub-district office (อบต. or municipality) collects land tax but is not obliged to disclose taxpayer names. Asking locals is free, but you need to be there, and what people tell you may be out of date.

Which should you choose?
- Doing a transaction: go to the land office.
- You have the deed number, a clear interest and can travel: the land office is the most direct route.
- You only need area, location or appraisal: LandsMaps is free and enough.
- You only have a map location, or you're far away: our service can save the first legwork. Verify at the land office before you transact.
Contact owners politely and respect a "no". Never use owner information to harass anyone. Landowners can object to their parcel being offered on our landowner page.
