"Just get the Chanote" — that's the advice every Phuket property lawyer will give you, and they're right. But what does that actually mean? And what happens when the property you're looking at doesn't have one?
Thai land titles are a system that evolved over decades, layered with different levels of rights, different degrees of certainty, and different risks. Walking into a Phuket property purchase without understanding the difference between a Chanote and a Nor Sor 3 is like buying a car without knowing whether it has a clean title or a stolen vehicle report. This guide explains every title type you'll encounter in Phuket, clearly.
Title deed verification must be done by a lawyer at the Phuket Land Office — not by the agent, not by the developer's lawyer, and not by looking at a photocopy. Budget ฿15,000–40,000 for proper legal due diligence. It's the cheapest insurance you'll ever buy.
The Thai Land Title Hierarchy
Thai land titles work as a hierarchy, from highest certainty to lowest. Here's the complete picture for Phuket:
| Title Type | Thai Name | Abbreviation | Security Level | Can be Sold/Mortgaged? |
|---|---|---|---|---|
| Chanote | โฉนดที่ดิน | NS4 / NS4J | ⭐⭐⭐⭐⭐ Highest | Yes — freely |
| Nor Sor 3 Gor | นส.3ก | NS3K | ⭐⭐⭐⭐ High | Yes — with restrictions |
| Nor Sor 3 | นส.3 | NS3 | ⭐⭐⭐ Medium | Yes — higher boundary dispute risk |
| Sor Kor 1 | สค.1 | SK1 | ⭐⭐ Low | Very limited — occupancy right only |
| Por Bor Tor 5 | ภบท.5 | PBT5 | ⭐ Very Low | No — not a title deed |
| Sor Por Gor | สปก. | SPK | ⭐ Very Low | No — agricultural reform, cannot be sold normally |
Chanote (NS4): The Gold Standard
Chanote (โฉนดที่ดิน) is Thailand's highest land title. It means:
- The land has been precisely surveyed using GPS/aerial photography and marked with permanent concrete boundary posts
- The survey is registered and verifiable at the Land Department
- Full ownership rights are unambiguous — you know exactly what you're buying
- The land can be mortgaged with Thai banks, sold freely, and transferred to heirs
- Any encumbrances (mortgages, leases, rights of way) are registered on the back of the title document and visible at the Land Office
For any property purchase in Phuket — condo, villa, land — insist on Chanote title for the underlying land. There is no good reason to accept anything less for a significant purchase, and Phuket has plenty of Chanote-titled land available. Any agent who pushes back on this requirement is a red flag.
NS4J vs NS4: You'll sometimes see "NS4J" — this refers to a Chanote updated with the more modern GPS survey system (จัดรูปที่ดิน). Both are full Chanote title. The 'J' variant simply has more precise modern boundary coordinates.
Nor Sor 3 Gor (NS3K): Generally Acceptable
Nor Sor 3 Gor (นส.3ก) is the second tier. It's a confirmed land certificate (confirmed meaning the land has been surveyed, though to a slightly less precise standard than Chanote). The key points:
- Aerial surveying has been done; boundaries are defined but using an older methodology
- Can be freely sold and mortgaged in most cases
- Higher risk of minor boundary disputes than Chanote, though uncommon in well-established areas
- Can usually be upgraded to Chanote at the Land Office for a fee (varies by land size; typically ฿3,000–20,000)
- As a condition of purchase, you can request the seller upgrade to Chanote before completion — this is entirely reasonable to ask
NS3K is found throughout Phuket, particularly in areas where land was titled before the modern GPS survey program. Many legitimate and valuable properties have NS3K title — it's not automatically a dealbreaker, but always get it independently verified and consider requesting an upgrade.
Nor Sor 3 (NS3): Use Caution
Nor Sor 3 (นส.3) is similar to NS3K but without the confirmed aerial survey. The boundaries may be approximate, based on historical markers rather than precise measurement. Risks include:
- Boundary disputes with neighbouring parcels (more common than with Chanote or NS3K)
- Encroachment issues — the land you think you're buying may overlap with a road, waterway, or neighbour's land
- More difficult to mortgage with Thai banks
- Can be upgraded to NS3K or Chanote, but the process is longer and more complex
For land purchases in Phuket, avoid NS3 if possible. If you find a property with NS3 title, it's not necessarily fraudulent — much of rural Phuket has older title types — but insist on a boundary survey and professional land inspection before any money changes hands.
Titles to Avoid: SK1, PBT5, and SPK
Sor Kor 1 (SK1)
SK1 is a notification of right to use land — essentially, a historical acknowledgement that someone has been farming or occupying the land. It is not a title deed and does not convey full ownership. SK1 land cannot be mortgaged with banks and is highly vulnerable to claims from the government or other parties. Do not buy or lease land with SK1 documentation.
Por Bor Tor 5 (PBT5)
PBT5 is an agricultural tax payment receipt, not a title deed at all. It confirms that someone has paid local land taxes on a piece of land, but it does not confirm they own it or have any formal rights to it. Do not accept PBT5 as evidence of land ownership.
Sor Por Gor (SPK)
SPK certificates were issued to low-income farmers under land reform programs and can only be used by the recipient for agricultural purposes. SPK land cannot be legally sold or transferred to a third party. Any "sale" of SPK land is void under Thai law. There have been cases in Phuket where foreign buyers have paid significant sums for SPK land under the impression it was properly titled. Do not buy or build on SPK land.

How to Verify a Title Deed in Phuket
The process is straightforward but must be done in person (or by your lawyer on your behalf) at the Phuket Land Office:
- Get the title deed number and land office number from the seller or agent. Every Chanote has a unique document number (เลขที่โฉนด) and a land office reference.
- Visit Phuket Land Office (กรมที่ดิน), Damrongracha Road, Phuket Town. Opening hours: Monday–Friday, 08:30–16:30. Your lawyer does this for you as part of due diligence.
- Request an official search (ตรวจสอบโฉนด). This confirms: the registered owner, whether there are any registered mortgages, any registered leases or usufructs, any encumbrances or legal restrictions, and that the title is genuine.
- Commission a boundary survey (รังวัดที่ดิน). A licensed land surveyor (สถาปนิก) can physically verify that the on-site boundaries match the title document. Cost: ฿5,000–15,000. Essential for any land purchase.
Condo Ownership: A Different Document
For condo purchases, the title document is not a land title at all — it's a Condominium Act ownership certificate (หนังสือกรรมสิทธิ์ห้องชุด, or อ.ช.2). This is the document that records your ownership of a specific unit within a registered condominium building. The underlying land will have a Chanote title registered to the juristic person (the condo management company) or original developer.
Key things to verify for condo purchases in Phuket: that the building is properly registered under the Condominium Act, that the foreign ownership quota in the building hasn't been exceeded (49% foreign maximum), and that there are no outstanding service charge debts on the unit.
