Land titles on Koh Phangan: Chanote vs Nor Sor 3, and how to verify one

On Koh Phangan, the single most important document in any land deal is the title deed — and not all titles are equal. The class of title decides whether you're buying real, transferable ownership or a piece of paper that can't be legally sold at all. Here's how they rank, and what due diligence has to confirm.

The title classes, strongest to weakest

• Chanote (Nor Sor 4 Jor, โฉนดที่ดิน) — the full ownership title deed. GPS-surveyed with concrete boundary markers; can be sold, mortgaged and subdivided. The gold standard — this is what to aim for.
• Nor Sor 3 Gor (น.ส.3ก) — a certificate of use with an aerial parcel map. Transferable, and can be upgraded to a Chanote. Boundaries are defined but without marked posts; transfer doesn't need a public notice. Usually fine with proper checks.
• Nor Sor 3 (น.ส.3) — older, with vaguer boundaries and no parcel-map link. Transfer requires a 30-day public posting. Workable, but needs more caution.
• Sor Kor 1 (สค.1) — an old notification of possession, not a title; registration has been effectively closed since 2008. Weak.
• Por Bor Tor 5 / 6 (ภบท.5) — not a title at all — it's a land-tax payment receipt, often over state or forest land. It cannot be legally owned or transferred. A classic island trap, marketed cheaply as “land with possession.” Avoid.
• Sor Por Kor 4-01 (สปก.) — agricultural land-reform land, reserved for qualified Thai farmers. It can't be sold to others or used to build a villa. Avoid.

How to verify a title

A title deed is only as good as what the Land Office record says about it. Verification means reading the official record, not trusting the seller's copy.

• Compare the original deed against the Land Office's record copy at the Koh Phangan Land Office. The back of the deed logs everything registered against it: ownership history, mortgages, leases, usufructs, servitudes and court orders.
• Commission a GPS boundary survey by a licensed surveyor and walk the plot — confirm the posts match the deed.
• Confirm registered road access. Landlocked plots are common, and a right of way has to be registered, not just verbal.
• Check what you can build. A clean title tells you what you own; the 2025 environmental zoning tells you what's buildable — see Building zones on Koh Phangan.
• Make sure it isn't forest reserve, Sor Por Kor, or encroached state land — and for a leasehold, that the lease is registered on the back of the deed.

Phangan in particular

A lot of island land is held as Nor Sor 3 Gor rather than Chanote — that's normal here, not a red flag in itself. The real traps are Por Bor Tor 5 “possession” land sold as if it were ownership, and beachfront or hillside plots that carry a clean title but are effectively unbuildable under the ecozone rules. Both look fine until you check.
