Thai land title deed types, explained

The Chanote is a full title deed, fixed by an actual field survey using boundary markers or GPS coordinates. Its area figure is the most precise of any Thai land document. Owners can sell, mortgage, or transfer it with complete legal certainty.

There are a few Chanote sub-variants, with the standard red-crest version the most common. Some older issues used slightly different survey standards than today's, but all still represent full, transferable ownership. Once you have the area figure, convert it to square metres at the land area converter.

Nor Sor 3 Gor is positioned using aerial photo maps, giving it a fairly clear boundary reference — it can usually be upgraded to a Chanote through an additional survey without much difficulty. Nor Sor 3 and Nor Sor 3 Kor lack that aerial-map reference and only place a plot roughly.

Both can be legally bought, sold and transferred, but their area figures should be treated as approximate. Verify the number with the local Land Office before using it in a sale price or calculation.

Sor Kor 1 is simply a record that possession was once declared to the authorities — it is not proof of ownership, and in many areas it can no longer be upgraded into a new title document. Land status needs careful checking before it's considered for purchase.

Sor Por Kor 4-01 is a land-use right inside an agricultural land reform zone, granted only to qualifying farmers under the relevant law. It cannot be freely bought and sold the way a full title can, and transactions bypassing the proper legal process carry significant legal risk.

Reliability roughly ranks Chanote → Nor Sor 3 Gor → Nor Sor 3 / Nor Sor 3 Kor → Sor Kor 1. The lower the tier, the more its area figure should be treated as an estimate rather than an exact number. For where to find and how to read the area figure on a Chanote, see How to read a Thai title deed for its rai-ngan-wah area.

Before any land purchase, check the document type, ownership status, and any encumbrances (mortgages, easements, etc.) at the local Land Office, and consult a land-law professional before deciding.

Every tier of Thai land document is issued and registered by the Department of Lands (dol.go.th), the authoritative source for checking a plot's status, document type, and registration history.

If you're unsure which tier of document a plot you're considering actually holds, the local Land Office branch covering that area can confirm it directly — have the title or plot number ready to speed up the check.

The table below sums up what fixes each document's boundary, how far its area figure can be trusted, and whether the land can be sold or transferred.
