Landlocked land on Koh Phangan: the statutory way of necessity vs. a registered servitude

If a plot you're considering has no direct frontage on a public road, does it automatically come with a legal right to cross the neighbour's land to reach one? Sometimes — but only under a specific statutory mechanism, and it's not the same thing as the registered access rights many sale listings casually call an 'easement.' Thailand's Civil and Commercial Code (CCC) actually provides two distinct legal routes to solve a landlocked plot's access problem, and which one applies changes what you can rely on as a buyer.

Route one: the statutory way of necessity (CCC Sections 1349-1352)

Section 1349 of the CCC gives the owner of land 'surrounded' by other land, with no access to a public way, the right to pass over the surrounding land to reach one — the passage must meet the landlocked owner's needs while causing as little damage as possible to the land crossed, and compensation is normally payable to the owner of the land crossed. This right exists by operation of law; it doesn't need to be negotiated, agreed, or registered to arise.

• The compensation flips off in one specific case. Section 1350 carves out an exception: if the landlocked condition was created by subdividing or partially transferring a larger plot — the classic case of a developer splitting land into parcels and leaving one without frontage — the resulting right of way runs only over the specific land that was split off, and no compensation is payable for it. This is the scenario most relevant to buyers of subdivided plots on Phangan's hillsides and interior.
• It's a personal right tied to the need, not an automatic entry on the title. A way of necessity isn't self-evidently visible on a chanote in the way a registered servitude is — it exists because the statutory conditions are met, and if the neighbouring owner disputes its scope or route, it can end up argued in court.

Route two: a registered servitude (CCC Sections 1387-1401)

A servitude (ภาระจำยอม) is a different, real right attaching to the land itself: the owner of one plot (the servient estate) is bound to tolerate a specific use by, or refrain from exercising some right against, the owner of another plot (the dominant estate) — access, but also drainage, utility lines, or a shared wall. Unlike a way of necessity, a servitude has to be created — either by explicit agreement registered at the Land Office, endorsed on the back of both title deeds, or by ten years of open, continuous, peaceful use (acquisitive prescription under Section 1401). It can also be extinguished by ten years of non-use (Section 1399).

• Registration is what makes it bind a future buyer. A registered servitude runs with the land — sell either plot, and the right and the obligation both survive the sale. An informal arrangement with the current neighbour that was never registered does not automatically bind whoever buys the neighbouring plot next.
• Prescriptive servitudes are real but hard to prove. A ten-year history of unregistered use can ripen into a servitude, but establishing that in practice usually means convincing the Land Office or a court that the use was open, continuous and without the servient owner's objection for the full period — not something to assume you can rely on without documentation.

Why the difference matters when you're buying

• Check the title deed's annotations, not the marketing description. A registered servitude will be noted on the back of the chanote for both the plot you're buying and the neighbouring plot it crosses — that's your evidence it exists and binds successors. If a seller or agent describes 'access rights' without a servitude annotation, ask what the actual legal basis is.
• A 'way of necessity' claim needs its own scrutiny. If access instead rests on Section 1349-1350, confirm precisely how the landlocked condition arose — was this parcel split off from a larger one (no compensation owed, route fixed to that specific transferring land) or is it landlocked independent of any prior subdivision (compensation ordinarily owed, route negotiated for minimum damage)? This affects both your legal footing and what you may owe a neighbour.
• An unregistered handshake arrangement is the weakest position of all. If the current owner simply has an informal understanding with a neighbour, neither a future dispute nor a future buyer of the neighbouring land is bound by it — get it converted to a registered servitude, or confirm a genuine statutory way of necessity applies, before you rely on it.
• This is a bigger issue on interior and hillside plots. Landlocked and semi-landlocked parcels are more common away from Phangan's ring road, on subdivided hillside land and inland lots reached only via a track over someone else's property — exactly the terrain covered in Hillside building limits in practice and buying next to undeveloped land.

The takeaway: 'this plot has access' is not a single legal fact — it's either a statutory right that exists whether or not it's written down, or a registered real right that has to be created and endorsed to count. Before you commit to a plot without direct road frontage, have your lawyer confirm on the actual title deeds which one you're getting, not which one a listing implies.
