Chanote and other Thai title deeds: what each grade means
The title deed is the ground truth of a Thai property. The strongest grade is the Chanote (Nor Sor 4 Jor); the others carry weaker rights. This guide explains what each grade means, why the chain of titles matters as much as the current grade, and where titles are searched and verified.
What the grades mean
The Chanote (Nor Sor 4 Jor) is the strongest Thai title deed: full ownership, GPS-surveyed, and the only grade that supports confident purchase. The three weaker grades each carry weaker rights, and they do not mean the same thing.
Nor Sor 3 Gor (NS3G) is a confirmed right of possession, surveyed but not fully titled. Nor Sor 3 (NS3) is a right of possession with unsurveyed boundaries. Sor Kor 1 (SK-1) is a claim of occupancy only, and it appears as the origin of many chains.
What the grades mean, in one line:
- Chanote (Nor Sor 4 Jor) — full ownership, GPS-surveyed; the strongest grade.
- Nor Sor 3 Gor (NS3G) — confirmed right of possession, surveyed but not fully titled; upgradable.
- Nor Sor 3 (NS3) — right of possession with unsurveyed boundaries.
- Sor Kor 1 (SK-1) — claim of occupancy only; often the origin of a chain.
The chain matters as much as the current grade
The current grade is only half the picture; the chain behind it is the other half. A history like SK-1 → NS3G → Chanote, subdivided in 2024, is a normal, checkable progression: a claim of occupancy, then confirmed possession, then full ownership, with the parcel subdivided along the way.
Gaps in the chain, or a very recent upgrade, warrant scrutiny. They are watch-items, not findings in themselves — but they are exactly what a verification exists to surface.
Where titles are searched
Titles are searched at the Land Office — the provincial office where titles are searched, encumbrances registered and transfers executed. Physical presence there is often required. 'We checked online' is not a title search.
The verification does its title checks there: a deed's authenticity, and what is registered against it, are confirmed against the office's records.
What weaker grades mean for a buyer
A weaker grade means weaker rights, and the difference is practical. Nor Sor 3 Gor is surveyed and confirms possession, but is not fully titled — and it is upgradable. Nor Sor 3 has unsurveyed boundaries, and Sor Kor 1 is a claim of occupancy only. Only the Chanote supports confident purchase.
About the title itself, the verification checks three things: the deed's authenticity at the Land Office, the full chain of grades behind the current one, and the subdivisions. A parcel sold off a mother title — the parent parcel a development subdivides from — is a usual failure point: villas are often sold before the subdivision completes.
What Suradeed is, and is not
Suradeed is not a law firm and gives no legal advice. Every legal finding and recommendation in a verification certificate is produced and signed by a licensed Thai law firm, which is responsible for it. Suradeed defines the verification protocol, coordinates the work, controls its quality and delivers the result.
You are billed in two lines for that reason: the partner firm's fee, which Suradeed collects as payment agent for the firm, and Suradeed's own platform and coordination fee. Your invoice shows both. Suradeed accepts no commission or referral benefit from any seller, developer, agent or broker — independence is contractual, not a policy statement.
FAQ
What is the strongest Thai title deed?
The Chanote (Nor Sor 4 Jor). It is full ownership, GPS-surveyed, and the only grade that supports confident purchase. The weaker grades — Nor Sor 3 Gor, Nor Sor 3 and Sor Kor 1 — carry weaker rights.
What does 'the chain' mean?
The chain is the history of the title — the grades it passed through to reach its current one. A history like SK-1 → NS3G → Chanote, subdivided in 2024, is normal and checkable. Gaps in the chain, or a very recent upgrade, warrant scrutiny.
Can a Nor Sor 3 Gor be upgraded?
Yes. Nor Sor 3 Gor is surveyed but not fully titled, and it is upgradable. An upgrade is a change in the chain, and like any recent change it warrants scrutiny.
Is an online check enough to verify a title?
No. Titles are searched at the Land Office, and physical presence there is often required. 'We checked online' is not a title search.
What happens if the chain has gaps?
Gaps warrant scrutiny before any payment milestone — they are watch-items, not findings in themselves. The verification reports what it finds in the chain, and the partner firm assesses what it means. A red flag is a deliverable, not a failure.
