Superficies in Thailand
Superficies (Sidhi-thos) under the Civil Code lets you own a building on land owned by someone else. It is typically paired with a registered lease in villa and estate schemes across Phuket, Samui, and Hua Hin.
Compare our property hub with the superficies overview before committing to any off-plan villa.
The superficiary holds registered ownership of the building, not the land plot.
Thai landowner keeps Chanote or Nor Sor land title throughout the term.
Registration at the Department of Lands creates priority against subsequent land transfers.
Superficies duration is usually tied to the registered land lease term.
Common foreign buyer structure
Most lawful villa purchases for foreigners follow a dual-registration sequence at the Department of Lands.
| Step | Action |
|---|---|
| Step 1: Land lease | Register 30-year lease at Land Office before or with superficies |
| Step 2: Superficies deed | Register building ownership right on same land title record |
| Step 3: Building permit | Confirm construction matches registered superficies scope |
| Step 4: Assignment rights | Contract must allow transfer to buyer or heirs if resale planned |
| Step 5: Renewal planning | Treat renewal promises as enforceability questions for your lawyer |
Registration workflow
Land Office registration creates enforceable priority. Unregistered villa contracts do not substitute for entries on the Department of Lands land record.
Title due diligence
Lawyer verifies land title category, encumbrances, and seller authority before any villa deposit.
Draft Thai instruments
Lease and superficies agreements prepared in Thai for Land Office registration.
Register land lease
First registered lease creates possessory right up to statutory 30-year maximum.
Register superficies
Second registration records building ownership separate from land title.
Verify land record
Obtain updated title extract showing both lease and superficies annotations.
Plan exit or resale
Confirm assignment procedure and fees before you need to sell the villa interest.

Risks to watch
Superficies schemes fail when registration or renewal assumptions break down. Review these risks with independent counsel.
- Lease non-renewal threatens land use despite believing you own the villa outright
- Disputes over maintenance and removal of structure at term end
- Unregistered superficies not enforceable against buyers of underlying land
- Assuming marketing language about 90-year ownership equals registered rights
- Skipping title search on coastal or resort land with complex history
Frequently asked questions
General answers for expats buying or holding property in Thailand. This is orientation, not legal advice for your specific transaction.
Q:How does superficies work in Thailand?
A:The superficiary owns the building while the landowner retains land title. Both rights must register at the Department of Lands to bind third parties.

A:Foreigners cannot own land. Registered lease secures land use while superficies secures building ownership on that leased plot.
Q:What are registration fees?
A:Land Office fees follow DOL tariff based on registered values. Lawyer prepares instruments and coordinates dual registration.
Q:Can superficies outlive the lease?
A:Practical enforceability depends on contract and registration. Term mismatch creates serious risk. Align both with lawyer guidance.
Q:What happens at lease expiry?
A:Contract should address structure removal, renewal, or compensation. Disputes here are common without clear drafting.
Q:Can I finance a superficies villa?
A:Thai bank mortgage on leasehold villa interests is difficult for foreigners. Plan cash purchase or developer financing with lawyer review.
