One property, several different rights
Land ownership, building ownership and the right to use land are separate legal matters in Thailand. “Freehold” describes ownership, while “leasehold” describes a time-limited right under a lease.
For any villa, establish who owns the land, who owns the building and which rights are actually registered.
Freehold land and Thai companies
Freehold land is generally held by Thai individuals or qualifying Thai companies. A company with foreign shareholders may qualify when at least 51% is genuinely Thai-owned and foreign participation does not exceed 49%, subject to other legal tests. The Thai partners must be real investors and shareholders. Narrow statutory exceptions to foreign land ownership exist but are not the usual villa-buying route.
News about “nominee crackdowns” concerns arrangements where apparent Thai shareholders do not act as genuine owners. It does not mean that legitimate joint ventures are prohibited. Share percentages alone never prove legal eligibility.
Ownership of the villa itself
A foreign individual can own a house or villa separately from the land when the necessary legal rights and documents are established. The building may also belong to a Thai individual or company, with the buyer's contractual or beneficial interests documented separately. A beneficial interest is not automatically the same as registered legal ownership.
A superficies or other properly registered rights can sometimes protect ownership of the building. The exact arrangement must be reviewed with the owner and a local lawyer.
Leasehold and sublease
A registered long-term lease is a common solution for foreign buyers of villas and investment properties. An ordinary land lease runs for up to 30 years per registration. The lessor may be a landowner, a company or joint owners. A sublease may also be used when the primary lease permits it; it cannot simply exceed the rights or remaining term of that primary lease.
A lease is not ownership of the land. Renewals are possible but not guaranteed. Assignment, inheritance, subletting and building ownership depend on the agreement and registration.
Leasehold: advantages
- Established, commonly used structure for foreign villa buyers.
- A registered term and contractual conditions provide clarity.
- Can be combined with separately documented building rights.
Leasehold: limitations
- The remaining term becomes shorter over time.
- Renewal is not automatic or guaranteed.
- Subleases, transfers and succession require appropriate terms and registration.
Sap-Ing-Sith and other rights
Sap-Ing-Sith is a separate registered property right, available for up to 30 years. During its term it can generally be transferred, inherited or mortgaged. It is not freehold land ownership and cannot be registered over only part of a property shown on one Chanote.
Superficies may protect ownership of a building on another person's land; usufruct grants rights of use and enjoyment. These rights are not interchangeable, and their suitability depends on the property.
Foreign Quota, Thai Quota and condominiums
Foreign Quota refers to eligibility for foreigners to own units in a legally registered condominium, within 49% of the total unit floor area. The remaining area is reserved for Thai-qualified ownership (Thai Quota). “Foreign quota” is not another name for freehold: an eligible condo unit may be owned freehold, while the quota describes who may hold it. Thai-quota units may sometimes be leased to foreign buyers.
On Koh Samui, villas are a major part of the market and condominiums are less characteristic of the island. Applicable municipal restrictions generally keep permitted condominium buildings low-rise, including 12-metre limits in specified zones. A villa-style unit can also form part of a registered condominium; its legal registration and quota, not its appearance, determine the ownership rules.
Check the structure before purchase
For off-plan and completed property, verify the Chanote, legal access, construction permissions, building title, lease or sublease, remaining term, restrictions and resale conditions. Market demand matters as much as the legal label.
Engage an independent Thai lawyer who regularly works with the Land Office in the area of purchase. Local registration practice can differ, even under the same national law.
