Why the Title Deed Decides Everything
When buying property in Thailand, the title deed is the single most important factor. It determines what rights you actually acquire – and which ones you don't. Unlike many Western countries, Thailand has different levels of ownership rights, and not every document offers the same protection. If you're not careful, you might be buying less than you think.
The Four Title Documents
Thailand recognises four types of title documents, which differ significantly in their legal security:
Chanote (Nor Sor 4 Jor)
The gold standard. A Chanote is a full ownership certificate with GPS-surveyed boundaries, registered at the Land Department. It offers the highest legal security and is the only title type that can be sold, mortgaged or encumbered without restrictions. When buying property, always insist on a Chanote.
Nor Sor 3 Gor
Also offers good security. The land has been surveyed and mapped by the Land Department, though not with the same GPS precision as a Chanote. A Nor Sor 3 Gor can be upgraded to a Chanote and is acceptable for most transactions in practice. A 30-day public notice is required when selling.
Nor Sor 3
Grants possession and usage rights, but not full ownership in the strict sense. Boundaries have not been precisely surveyed, which can lead to boundary disputes. The 30-day notice requirement also applies here.
Sor Kor 1
Merely a possession notice – proof that someone uses the land. It is not a title deed and cannot be legally sold or transferred. Stay away from properties with Sor Kor 1.
Freehold vs. Leasehold
Freehold means full ownership – you own the property in your name, indefinitely, inheritable and freely transferable. For foreigners, freehold is only possible for condominiums (registered apartment buildings where individual units are sold separately). The so-called 49% rule means that a maximum of 49% of the total sellable area of a building may be foreign-owned. Your individual unit belongs to you 100% – the quota applies to the building as a whole, not to your apartment. When buying a condo freehold, your name is entered directly on the back of the Chanote.
Leasehold is a lease agreement – you acquire the right to use the property for a specific period. Thai civil law limits registered leases to a maximum of 30 years. Renewal clauses are common but legally problematic: the Supreme Court has repeatedly ruled that renewal promises are not automatically enforceable. A leasehold therefore always carries some risk – particularly if the lessor sells, dies or becomes insolvent.
Additional Security Instruments
Experienced buyers combine leasehold with additional legal protections:
Usufruct: A right registered at the Land Department to use the property and derive income from it – either for a fixed term or for life. A usufruct survives a change of land ownership, making it particularly valuable.
Superficies: The right to own a building on someone else's land. If you build a house on leased land, a superficies right secures your ownership of the building itself – independent of the land.
Right of First Refusal: A registered notation giving you pre-emptive purchase rights if the landowner wishes to sell.
Which Ownership Type Is Right?
For most foreign buyers, we recommend: If you want to buy a condo, freehold is the clear first choice – provided the foreign quota hasn't been exhausted. For houses and villas, a leasehold combined with usufruct is the safest option. Make sure both rights are registered at the Land Department – an unregistered contract offers little protection.
