Civil and Commercial Code - Superficies
Civil and Commercial Code ss.1410-1416
The information is reviewed and updated monthly against official sources.
In short
Sections 1410-1416 of Thailand's Civil and Commercial Code establish the right of superficies, which lets a person legally own buildings, structures, or plantations on land belonging to someone else, a key lawful route for foreigners to own a house without owning the land beneath it.
1410: Creation of a right of superficies
A landowner may grant another person a separate property right to own buildings, structures, or plantations located on top of or beneath the land. This splits ownership: the land stays with its owner while the holder of the right (the superficiary) owns the construction, a structure widely used so foreigners can lawfully own a house in Thailand.
1411: Transfer and inheritance of the right
Unless the document creating the right states otherwise, a superficies can be sold, assigned, or otherwise transferred, and it also passes to heirs on the holder's death. This gives the right real economic value and continuity, so a foreign owner can leave the house to family or sell the building separately from the land.
1412: Term: fixed period or for life
A superficies may be set either for a fixed number of years or for the lifetime of the landowner or of the holder. When a fixed term is chosen, the thirty-year ceiling applicable to similar real rights applies: any agreed period longer than thirty years is automatically cut back to thirty, though renewal can be arranged afterward.
1412-renewal: Renewal of a fixed-term superficies
Because the maximum single term is thirty years, parties wanting longer security commonly agree to renew. A renewal becomes enforceable as a real right only when registered again at the Land Office at or near expiry; a mere promise to renew binds the parties contractually but does not by itself bind future buyers of the land.
1413: Termination when no term is fixed
If no period was agreed, either party may end the superficies at any time by giving the other reasonable advance notice. Where rent is payable, the party ending it must give at least one full year's notice or, alternatively, pay one year's rent. This protects the holder from abrupt loss of an indefinite arrangement.
1414: Termination for breach or non-payment
The landowner may terminate the right if the holder breaches essential conditions written into the grant. Where rent is due, failure to pay it for two consecutive years is also grounds for termination. Foreign buyers should therefore meet all stated conditions and keep rent current to avoid losing the right to their building.
1415: Survival of the right after destruction of the building
The superficies does not end merely because the building, structure, or plantation is destroyed, even when the loss results from force majeure such as fire, storm, or flood. The holder keeps the underlying right and may rebuild within the original term, which is significant security for an owner of a house on land they do not own.
1416: Removal of the building on extinction; landowner's buy-out option
When the right ends, the holder may take away the buildings, structures, or plantations, but must return the land to its prior state. Instead of allowing removal, the landowner may declare an intention to buy them at market value; the holder cannot refuse that offer unless there is a reasonable ground for doing so.
registration-requirement: Registration as a real right at the Land Office
A superficies becomes a genuine property right binding on third parties only once it is registered against the land title at the Land Department. An unregistered agreement creates merely personal obligations between the parties. Foreign buyers should insist on registration on the title deed so the right survives a later sale of the land.
foreigner-house-ownership: Foreigners owning a house via superficies
Foreigners cannot own land in Thailand, but they can lawfully own a house on Thai land by registering a superficies in their own name. The structure is then their separate property, distinct from the land. This is a recognized, court-backed alternative to relying solely on a long lease for residential security.
land-sale-effect: Effect of a later sale of the land
Once registered, a superficies stays attached to the land and binds anyone who later buys it; the new landowner takes the plot subject to the existing right. The holder's ownership of the building is therefore not defeated by a change of landowner, which makes the right far more secure than an unregistered arrangement.
rent-and-consideration: Rent and consideration for the right
A superficies may be granted free of charge or in return for rent or a lump-sum payment, as the parties agree in the creating document. The presence of rent changes the termination rules: it triggers the one-year notice requirement and the two-year non-payment cancellation ground, so payment terms should be defined clearly.
