Can the government take your land? Expropriation compensation rights in Thailand

Can the Thai government take privately owned land for a public project — a road widening, the proposed Samui-Phangan sea bridge, or a new cruise pier — and if so, what do you actually get paid? Yes: under the Expropriation and Acquisition of Immovable Property Act B.E. 2562 (2019), the state has the power to compel a sale for a defined range of public purposes, but the Act requires a structured process and fair compensation — it isn't a bare taking.

How expropriation starts

Expropriation begins with a royal decree that designates the affected zone — sometimes called an official 'red line' — for a permitted purpose: public utilities, roads and transport infrastructure, military use, agricultural development schemes, or town-and-country planning. From the decree date, land inside the zone faces development restrictions; major construction or modification generally needs special permission. Officials then survey and catalogue each parcel — land area, buildings, trees and other fixed assets — before a pricing committee sets compensation. Start to finish, the process commonly spans two to five years.

What compensation is supposed to cover

• Land — market value assessed as of the decree date, weighing location, permitted use and comparable actual sales.
• Structures — replacement cost less depreciation for houses, outbuildings, fences, water tanks and similar fixed improvements.
• Trees and crops — compensated against official per-tree or per-rai schedules rather than a case-by-case valuation.
• Relocation costs — demolition and moving expenses, and the practical disruption to livelihood.
• Damage to the remainder — if only part of a plot is taken and what's left is oddly shaped, loses road access, or can no longer be used as before, that diminished value is also compensable, not just the strip that was taken.

The compensation committee, and a legal wrinkle worth knowing

A committee formed under Section 19 of the Act announces the per-parcel figure. Thai legal commentary flags a structural quirk worth understanding rather than assuming: compensation set by this committee is treated as an administrative act, reviewable by the Administrative Court, while compensation written directly into a specific expropriation act of parliament is a legislative act and isn't subject to the same administrative review. In practice, almost every everyday expropriation (road projects, utility corridors) runs through the Section 19 committee route, so the Administrative Court avenue below is the one that matters for most owners.

Appeal rights — and why accepting payment doesn't end them

An owner who disputes the committee's figure can appeal to the responsible minister, generally within a statutory window reported as around 90 days from notice of the compensation decision. If that doesn't resolve it, the next step is the Administrative Court. Importantly, accepting the compensation payment does not by itself forfeit the right to appeal — sources are consistent that reserving your right to dispute the amount at the time you receive payment keeps the appeal open, so an owner facing a compulsory taking doesn't have to choose between taking the money and continuing to fight for a fairer figure.

This is a separate legal track from the government forfeiture covered in Land Code Section 94 and forced land sales — that mechanism punishes illegal foreign-linked landholding; expropriation compensates a lawful owner for land the state needs for a public purpose. For Phangan and Samui specifically, the proposed Samui-Phangan sea bridge and expressway and the Koh Samui cruise pier proposal are the kind of projects that would, if they proceed to a royal decree stage, trigger this process for any land along the designated route or landing site — worth asking about specifically if a plot you're evaluating sits near either alignment.
