"Untitled sea-view land" on Koh Phangan: why a PBT5 or Sor Por Kor plot can never become a chanote

Can a seller's promise that a cheap sea-view plot will "get its chanote soon" ever be true? If the document on offer is a Por Bor Tor 5 (PBT5, ภ.บ.ท.5) or a Sor Por Kor 4-01, the honest answer is: only if the land sits outside a national park, forest reserve or other restricted zone — and on Koh Phangan's hillsides and coastline, a great deal of it doesn't. Understanding what these documents actually are is the difference between buying land and buying a tax receipt.

What these documents actually are

• Por Bor Tor 5 (PBT5) — issued by the Subdistrict Administrative Organization, it records that someone paid a local land-use ("grass") tax. It is not issued by the Department of Lands, confers no ownership, and the Land Department will not register a sale, lease, mortgage, usufruct or superficies against it.
• Sor Por Kor 4-01 — an allotment from the Agricultural Land Reform Office for landless farmers to occupy and work state land. It confers a right to occupy and farm only, cannot be bought or sold, and can only pass by inheritance.
• Sor Kor 1 — a decades-old notification of possession with no registrable rights at all; weaker than either of the above.
• Chanote (Nor Sor 4 Jor) — the only document that is a true, government-surveyed ownership title, freely saleable, mortgageable and inheritable. See Land titles on Koh Phangan: Chanote vs Nor Sor 3 for the full comparison, including Nor Sor 3 Gor.

Why the upgrade promise so often can't be kept

A PBT5 or Sor Por Kor plot can, in principle, be surveyed and converted toward a title deed — but only for land the Land Department confirms sits inside a legitimate community or agricultural-use area, outside any national park, forest reserve, mangrove zone or military area. Much of Koh Phangan's most scenic land — hillside slopes and stretches of coastline offered as "sea-view" plots — falls inside or directly against national park and forest reserve boundaries mapped under the island's own hillside and forest-reserve enforcement sweep. Where that overlap exists, no survey, no waiting period and no relationship with a local official changes the outcome: the law does not permit an upgrade, full stop.

How to check before you pay a deposit

• Get the exact parcel/survey number off the PBT5 or Sor Por Kor document and take it to the Provincial or District Land Office yourself — not through the seller or their broker — and ask directly whether the parcel has ever been proposed for title upgrade and whether it overlaps a forest reserve or national park boundary.
• Ask the Royal Forest Department or National Park office to check the coordinates against gazetted reserve and park boundaries; overlap here is the single fact that makes an upgrade legally impossible, not just slow.
• Treat "the government is about to allow an upgrade" as a claim to verify, not a fact to accept — it is the most common line used to justify a below-market price on land that will never be sellable, mortgageable or insurable in the buyer's own name.
• Assume you cannot register anything against a PBT5 or Sor Por Kor document — no lease, no superficies, no usufruct — which rules out the standard compliant foreign-ownership structure entirely; see How foreigners legally own a villa.
• Walk away from any deal structured as a private "assignment" or possession-transfer agreement over PBT5 or Sor Por Kor land — these documents have no legal mechanism for a foreigner (or, in the case of Sor Por Kor, almost anyone) to acquire the underlying right by purchase.

If a plot is genuinely attractive, the only responsible next step is confirming it already carries a Chanote or, at minimum, a Nor Sor 3 Gor — and having a Thai lawyer verify that title independently at the Land Office before any money changes hands.
