Property law is one place where independent professional advice is not optional. The useful starting point, though, is uncomplicated: a foreign buyer can acquire a registered condominium unit within the foreign quota, while land and villa structures need a different and more cautious analysis. This guide explains the decision points before you speak to a lawyer.
Condos: the simple route
Foreigners can own a registered condominium unit freehold as long as it sits inside the building's foreign quota. The statutory ceiling is 49% of the total area of all units in the condominium, not simply 49% of the unit count. Inside the available quota, the buyer receives a condominium title deed rather than a time-limited lease.
Before signing, obtain a current foreign-quota confirmation from the condominium juristic person. The Department of Lands also requires the juristic person's debt-free certificate and foreign-quota certificate at transfer. A sales brochure saying “foreign freehold available” is not the same as the documents being ready.
When the quota is full
If the foreign quota is full, the Land Office cannot register that unit to another foreign freehold buyer. A seller or developer may offer a lease instead, but that is a different legal interest rather than a substitute form of freehold. Compare the registered term, termination clauses and any renewal promise with independent advice before paying a deposit.
Land and villas: the catch
Here's the big one: foreign ownership of land is generally prohibited, apart from narrow statutory exceptions requiring specific approval. A house or villa transaction may instead use a registered lease, or separate ownership of the building while the land is leased. A lease can be registered for up to 30 years; a promised renewal is a contractual promise and is not the same as having the next term already registered. Use an independent lawyer to test the title, contract and exit position.
Bringing the money in
A foreign freehold buyer normally has to show that the purchase funds were remitted into Thailand from abroad in foreign currency. Depending on the amount and bank process, the evidence may be a Foreign Exchange Transaction form or another bank confirmation accepted by the Land Office. Put the buyer and purpose details on the transfer correctly, keep the remittance documents and confirm the required wording with the receiving bank before sending the money.
Off-plan vs resale
A completed resale gives your lawyer an existing title deed, building records, common-area history and a unit that can be inspected. An off-plan purchase adds developer, construction and completion risk. Check the land title, planning and building permissions, environmental approvals where applicable, construction milestones, escrow or payment protections, completion remedies and exactly when the unit can be registered.
Do not treat a reservation form as harmless. It can set deadlines, refund conditions and a buyer identity before legal due diligence has happened. Ask for a review before paying a non-refundable reservation or signing a long-form contract.
The buyer due-diligence checklist
- Identity and authority: confirm the seller owns the unit or has lawful authority to sell it.
- Title: check the condominium title deed, registered encumbrances, unit area and parking or storage rights.
- Foreign quota: obtain a current certificate from the condominium juristic person.
- Building finances: review common fees, sinking fund, arrears, major planned works and juristic-person meeting records.
- Contract: identify deposit conditions, completion date, default remedies, fixtures, tax and fee allocation, and the governing-language clause.
- Money trail: agree the remittance wording and bank evidence before funds arrive in Thailand.
- Use and exit: check rental restrictions, management terms and what a future buyer would need from you.
What it costs
Do not rely on one headline percentage. A transfer fee is calculated on the official appraised value, withholding tax depends on the seller and holding history, and either stamp duty or specific business tax may apply depending on the facts. Lease registration has its own fee and stamp-duty treatment. The sale contract decides the commercial split, but it does not change what the Land Office assesses. Ask your lawyer for a written completion statement using the current official valuation before you commit.
Do it properly
Use an independent Thai property lawyer who represents you, not the developer or agent. Ask for the title, quota, contract and Land Office transfer documents to be checked before the deposit becomes non-refundable. For area fit, start with the where to live guide; for rental law and contracts, use the separate Phuket renting guide.
