Long-term leases now under nominee scrutiny too: what the August 2026 Koh Samui raid signals for Phangan buyers

Is a registered 30-year lease still the safe way for a foreigner to hold long-term rights over land on Koh Phangan? For a standard, single-term registered lease, yes — but as of mid-August 2026, Thai authorities have said publicly that the nominee-enforcement campaign is widening beyond companies to examine certain lease arrangements too. Here's the actual news, and where the line currently sits.

The 15 August 2026 raid: what actually happened

Described by officials as the seventh phase of the ongoing foreign-nominee-network crackdown, a coordinated operation involving 300+ police and officials reviewed all 12,906 companies registered on Koh Samui. Of those, 8,254 had foreign shareholders and 875 showed characteristics consistent with nominee arrangements. The review produced 60 criminal cases against 88 suspects (26 Thai nationals, 62 foreigners), 14 arrests of foreign nationals wanted on warrants, and identified 59 companies tied to 37 land plots and buildings worth an estimated ฿1.2 billion. Five business networks were targeted, spanning property development, unlicensed operations and suspected tax avoidance.

The new signal: leases under the same lens

A day earlier, on 16 August 2026, Thai Examiner reported that officials working the same Koh Samui-Koh Phangan enforcement push are now examining long-term leases as a possible alternative route foreigners use to secure effective decades-long control of land without appearing as a registered owner or a flagged company shareholder. Officials said the focus emerged from conversations with foreigners describing increased reliance on leasing over buying. This is a real, dated enforcement signal — but it is still an emerging one: reporting describes investigators "examining" whether particular lease structures circumvent ownership restrictions, without naming a specific statute, case, or enforcement mechanism yet. Treat it the way this site treats other studied-but-not-enacted proposals, such as the Section 94 forfeiture amendment: real, worth tracking, not yet a settled rule with a defined test.

What this does — and doesn't — mean for a standard lease-and-superficies buyer

• A single, cleanly registered 30-year lease combined with a registered superficies over the building — the structure this site recommends throughout, see How foreigners legally own a villa — is not, on current reporting, the type of arrangement under scrutiny. It's a standard, transparent property right, not a disguised ownership workaround.
• Stacked or serial leases (the '30+30+30' pattern marketed as 60 or 90 years of tenure) are the clearest candidate for this scrutiny — and separately, the pre-agreed renewal periods in those structures are already void as a matter of contract law under the March 2025 Supreme Court ruling. See Renewing a 30-year lease: what actually happens for that ruling in full.
• Leases bundled with side agreements — options to indefinitely extend without the landowner's fresh consent, loans from the lessee to the landowner secured against the land, or other arrangements that hand a foreign lessee decision-making or economic control beyond simple occupancy — fit the profile officials describe as giving 'effective control' without registered ownership.
• A lease used as a fallback after a company structure was rejected or flagged is exactly the kind of pattern that draws attention in an environment where officials are actively comparing notes across enforcement tracks.

Why Koh Phangan sits inside the same net as Koh Samui

Koh Phangan and Koh Samui share the same provincial jurisdiction (Surat Thani) for land registration and company oversight, and enforcement reporting through 2025-2026 has consistently treated the two islands as a single campaign area rather than separate cases — see Nominee-ownership enforcement spreads to Krabi for how the same push has moved across provinces, and 36,277 foreign-linked companies and 8 priority provinces for the parallel company-monitoring numbers behind this same crackdown.

Nothing here changes what a compliant lease looks like. It does mean documentation discipline matters more than ever: a single registered term, no side letters implying disguised ownership, rent and any option terms genuinely negotiated rather than pre-agreed for decades, and independent legal advice before signing anything a broker describes as a workaround for the 49% ownership cap.
