How to Check a Land Title Deed
Online in Thailand Before You Buy

You check a land title deed online in Thailand through the Department of Lands' free LandsMaps portal (landsmaps.dol.go.th), which lets you look up a parcel by province, district, and sub-district and see its surveyed boundary, size, and deed type against a satellite map. For a foreign buyer, this single check can be the difference between confirming the land you're about to commit to often through a Thai spouse or a long-term lease is exactly what the seller says it is, or discovering too late that the "title deed" was actually a weaker document, the boundary doesn't match what was walked on-site, or the land carries a mortgage nobody mentioned.

What Types of Land Title Deeds Exist in Thailand, and Why Does It Matter?

Thailand has several tiers of land documents, and only the strongest gives you a fully surveyed, individually titled parcel. The document commonly called a "Chanote" (Nor Sor 4 Jor) is the full title deed surveyed with GPS-accurate coordinates and boundary markers set in the ground, and freely transferable or mortgageable. Below that sits Nor Sor 3 Kor, a confirmed possessory right with boundaries plotted from aerial photographs rather than precise survey usable and transferable, but less exact. Weaker still is Nor Sor 3, where boundaries aren't formally demarcated and transfer requires a 30-day public notice period. At the bottom is Sor Kor 1, a mere notification of possession that is very difficult to build on or finance with confidence.

The problem foreign buyers run into most often is a seller describing land loosely as having a "title deed" or even a "Chanote" when the paperwork is actually Nor Sor 3 Kor or weaker. The deed type determines what you can legally do with the land including whether a bank will lend against it and whether a builder can safely start design and construction on it so confirming the exact type in writing is the first thing to verify.

Why Should You Check a Land Title Deed Online Before You Buy?

You should check the title online before you buy because it lets you independently verify the deed type, parcel boundary, and registered size instead of relying solely on what a seller or agent tells you. Land deals in Thailand can move quickly, sometimes with pressure to pay a deposit before documents are fully reviewed, and for a foreign buyer purchasing through a Thai spouse or a long-term lease, the paperwork is already unfamiliar. An independent online check costs nothing and gives you a second source of truth to compare against the physical land and the seller's copy of the deed.

It won't catch everything liens and some encumbrances are recorded on the back of the physical deed and aren't always visible on the public map but it's a free, essential first filter before you spend money on land in Thailand.

What Information Does an Online Title Check Actually Give You?

An online title check gives you the parcel's approximate location, boundary shape, and registered size overlaid on a satellite map, plus the deed type and survey number tied to that location a first-pass checklist before you go any further with a purchase.

✅ What a title deed check tells you:

• Deed type Chanote, Nor Sor 3 Kor, Nor Sor 3, or a weaker possessory document
• Parcel (title deed) number and survey page number, which should exactly match the seller's paper copy
• Registered land area, to compare against what a physical survey or measurement on-site shows
• The surveyed boundary shape and orientation, viewable against satellite imagery of the actual site
• Province, district (amphoe), and sub-district (tambon) the parcel is officially registered under

🚩 Red flags to look for:

• The online record shows a lower-tier deed type (e.g. Nor Sor 3) than what the seller verbally described (e.g. "Chanote")
• The mapped boundary shape doesn't match the shape of the land you walked or were shown on-site
• The registered size differs meaningfully from what's advertised
• The parcel appears to be an informal subdivision of a larger plot that hasn't gone through a formal, registered subdivision (split) process
• The seller is reluctant to let you see the original physical deed (not a photocopy) alongside your ID at the Land Office

How Do You Check a Land Parcel Online via the Department of Lands?

You check a land parcel online by using the Thai Department of Lands' free LandsMaps geographic information system, searching by location and deed/survey number to bring up the parcel boundary on a satellite map. The interface is in Thai, so it helps to have a Thai-speaking assistant, agent, or your builder's team on hand the first time you use it.

Can Foreigners Own Land in Thailand?

No under Thai law, foreign individuals generally cannot directly own land in Thailand. This is the single most important fact for a foreign buyer to understand before checking a title deed at all, because it changes whose name ends up on the document you're verifying. In practice, most foreign buyers build on land held in a Thai spouse's name, or secure long-term use through a registered lease (commonly up to 30 years, sometimes with renewal options). Both routes carry real trade-offs a foreign spouse is typically required to sign a declaration confirming they have no ownership claim over land registered to a Thai partner.

This article is not legal advice. Land-holding structures for foreigners carry real long-term consequences for inheritance, financing, and control of the property speak with a Thai property lawyer before deciding how the land, and later the house built on it, will be legally structured.

What Mistakes Do Buyers Make When Checking a Title Deed?

The most common mistake is accepting a photocopy of the title deed as sufficient proof, instead of insisting on seeing the original alongside the seller's ID at the Land Office copies are easy to alter or can be outdated if the land was subdivided since the copy was made. A close second is skipping the physical comparison step: checking the online map once and never actually walking that boundary against the real site, so a mismatch or encroachment from a neighboring plot goes unnoticed until construction planning begins.

A third, subtler mistake is not asking whether the parcel was legally subdivided from a larger plot. Land informally split among family members without the subdivision being registered and separately titled can leave the "parcel" you're buying without a clean, independent deed, which becomes a serious problem when you apply for a building permit or construction loan later. If the online record and the seller's story don't line up, treat it as a reason to slow down, not a detail to sort out after the deposit is paid.

Once your land and deed are confirmed, the next steps are choosing a house design that fits the plot and understanding how Landy Home's One-Stop Service process carries a project from land survey through to handover. Popular current designs like the Paddington-S Modern Classic house plan are a good starting point for browsing what's possible on a mid-sized residential plot, and if the project involves financing, Landy Home's home construction loan support service can help with the paperwork once your land title is confirmed.
