Land Title Deed Types in Thailand: Chanote, Nor Sor 3, and Nor Sor 4 Explained Before You Buy Land in Isaan

What Land Title Deed Types Mean Before You Buy Land in Isaan

A land title deed is the legal document that tells you exactly what rights you hold over a piece of land. Rights range from full ownership down to a temporary permission to farm state land. The Department of Lands (Krom Thi Din) issues and manages every one of these documents nationwide. Before you buy a plot in Korat, Roi Et, Khao Yai, or Pak Chong, the first thing to check is what the land title deed actually says, not just the price per rai.

Many buyers assume every land title deed type is basically the same, just with a different name. In reality, each type grants a different level of rights. Some can be sold, transferred, and mortgaged freely, while others cannot be sold at all except passed down as inheritance. This directly affects whether a bank will approve a construction loan and whether the local district office will approve a building permit, since both apply different rules depending on the document type.

A common problem on site is that a buyer has already purchased land and finalized a house design, only to hit a wall applying for a construction loan or building permit because the land documents do not meet the requirements. By the time this surfaces, months have often been lost. This article breaks down the land title deed types you will most commonly encounter outside Bangkok, so you can check them before signing a purchase contract.

Chanote (Nor Sor 4): Full Ownership Title

The chanote, officially Nor Sor 4, is the strongest form of land ownership document in Thailand. Officials issue it under Sections 58 and 58 bis of the Land Code, after a cadastral survey and proof that the land has been put to use. It comes with the most precise survey and cadastral map among all Thai land documents. The document page lists the exact area, plot position, and the registered owner’s name in full.

A chanote allows the owner to sell, transfer, mortgage, or subdivide the land freely under Thai law. Most banks approve construction loans most easily when a chanote is used as collateral, because the value and boundaries can be verified precisely. For land in Khao Yai or Pak Chong, where price per rai runs high, this document type is usually the first condition a bank sets before approving financing. It is worth noting here that foreigners generally cannot hold freehold land ownership in Thailand, so a chanote purchase by a foreign national typically has to go through a Thai company structure, leasehold, or a Thai spouse instead.

Owners holding a chanote can apply for a building permit with the local municipality or SAO (Subdistrict Administrative Organization, or Or Bor Tor) in a straightforward way. A copy of the chanote is attached to the construction permit application under the Building Control Act B.E. 2522, with no further proof of right required. If the land was just purchased, check that the registered owner’s name on the back of the chanote matches the sale contract before moving on to house design.

Nor Sor 3 vs Nor Sor 3 Kor: What Is the Difference

Both Nor Sor 3 and Nor Sor 3 Kor are certificates of use, not full ownership like a chanote, but unlike a reservation permit they can still be bought and sold. Nor Sor 3 Kor has already been surveyed using aerial photo cadastral mapping, so the plot boundaries are marked more precisely. Nor Sor 3, the older form, still relies on a looser aerial photo reference.

A Nor Sor 3 Kor can be registered for sale or mortgage at the land office immediately. A plain Nor Sor 3, however, requires a public notice period of approximately 30 days before any registration of rights or transactions, because the boundaries have not been surveyed precisely enough to confirm immediately (according to the Department of Lands). This delay catches many buyers in Roi Et off guard, pushing back a planned land transfer by approximately one month before house construction can even begin.

Both document types can be upgraded to a full chanote under Section 59 of the Land Code, once an official reviews and approves the request. Until that upgrade happens, some banks offer a lower construction loan amount against Nor Sor 3 Kor than they would against a chanote. Owners holding a Nor Sor 3 Kor who plan to borrow for construction should confirm loan terms with their bank before committing to the land purchase.

Reservation Permits and Sor Kor 1: Rights That Are Not Yet Complete

A reservation permit (Nor Sor 2) is a document that allows an individual to use state land for a specific purpose. It is not proof of ownership. The law prohibits transferring a reservation permit to another person except through inheritance (according to the Department of Lands). The holder must fulfill the land-use conditions in full before the permit can later serve as evidence to apply for a Nor Sor 3 or a chanote.

Sor Kor 1 is a declaration of land possession that residents filed before the Land Code came into force, meaning before December 1, 1954. It is not a title document issued by the government; it is only proof that someone once declared possession of the land (according to the Department of Lands).

Since February 9, 2010, land held under Sor Kor 1 can only be upgraded to a chanote or Nor Sor 3 once a final court judgment or order confirms possession before the Land Code took effect (according to the Department of Lands). This type of land shows up often in Isaan, since it is frequently land passed down from grandparents that was never formally titled. Buyers who come across Sor Kor 1 land should plan for the time a court process takes before thinking about house design at all.

ALRO Land (Sor Por Kor 4-01), Common on Farmland Across Isaan

Sor Por Kor 4-01 is a permit to use land within an agricultural land reform zone administered by ALRO (the Agricultural Land Reform Office). It is not a land title deed that can be freely bought and sold like a chanote. The law requires the land to be used primarily for agriculture, and prohibits subdividing or transferring the right to another person except through inheritance to a lawful heir, or transfer to an agricultural institution or ALRO itself, under Section 39 of the Agricultural Land Reform Act B.E. 2518.

This land type is common around Roi Et and the farmland surrounding Korat. Some buyers purchase Sor Por Kor land from a farmer through a private, unregistered sale agreement, then plan to build a permanent home on it. That conflicts with the law’s core condition that the land be used for agriculture. The risk is a later inspection that finds no legal right in the land the buyer paid for.

Applying for a building permit with a municipality or SAO requires attaching a copy of the correct land title document for the property type. Sor Por Kor land where the buyer is not the officially registered permit holder usually fails a building permit application outright. Before agreeing to buy cheap land anywhere in Isaan, always check with the provincial ALRO office or the land office to confirm exactly which land title deed type the plot actually carries.

How to Verify a Land Title Deed Before Design and Construction Begin

Before signing a land purchase contract, request a copy of the original land title deed from the seller. Then take the title number or cadastral reference to the local land office to confirm the document type, plot size, and registered owner all match what is actually being sold. This step takes little time but removes most of the problems that would otherwise surface later.

If a construction loan is part of the plan, confirm with the bank whether it accepts the specific document type as collateral, since terms vary by bank. Standard land office fees for a transfer and a mortgage registration run at approximately 2% and 1% of the appraised value respectively, though a current measure cuts both to 0.01 percent for a house or commercial building priced at no more than 7 million baht, running through 30 June 2027, so it is worth checking the rate at the land office before transferring (according to the Department of Lands). Issuing a chanote for an individual parcel after the survey is complete typically takes approximately 83 days or more, not counting the wait for a survey appointment, which varies by province from approximately 15 to 1,000 days (according to the Department of Lands).

The OBILIS team asks to see a copy of the land title deed every time before starting a house design, not out of distrust of the owner, but because a document problem is far harder to fix later than a design change. If the land is still held under a reservation permit, Sor Kor 1, or ALRO land, sorting out the paperwork should always come before choosing a house design.

Frequently Asked Questions

How does a chanote differ from Nor Sor 3 Kor for a construction loan

A chanote grants full ownership, so most banks accept it as collateral for the full construction loan amount. Nor Sor 3 Kor can legally be mortgaged too, but some banks offer a lower loan amount or attach extra conditions to it. Owners should check with their intended lender before deciding to buy the land.

Can land held under a reservation permit be sold privately

No. The law prohibits transferring a reservation permit to anyone except through inheritance (according to the Department of Lands). A private, unregistered sale of reservation-permit land therefore has no legal effect, and the buyer does not actually gain rights to the land.

Can you legally build a house to live in on ALRO land

The law requires land inside a reform zone to be used primarily for agriculture. Building a permanent residence unrelated to farming carries real risk of inspection, and a building permit application with the local authority commonly fails because the land document does not match the required type. Check with the provincial ALRO office before making any decision.
