For buyers considering Bangkok, the key questions are eligibility, the building’s foreign ownership quota and the documents needed to register a transfer.

Thailand Condominium Act: the main rules
The governing law is the Condominium Act B.E. 2522 (1979), as amended. The current consolidated text hosted by the Department of Lands sets the general foreign ownership ceiling at 49% of the total area of all condominium units, measured at registration. It is an area calculation, not simply a count of units. A qualified foreign buyer can own an individual unit outright. However, that does not mean foreigners can generally own an entire condominium project. Before choosing a unit, ask whether the proposed transfer fits within the building’s available foreign quota.Who qualifies for foreign condominium ownership?
Section 19 includes permanent residents, persons admitted under investment-promotion law, specified juristic persons and foreigners using qualifying funds. The funding route includes bringing foreign currency into Thailand or withdrawing from a qualifying non-resident baht or foreign currency deposit account. Under Section 19 ter, the supporting amount for this route must cover at least the unit’s purchase price. Ask an independent Thai property lawyer which category applies to you. Do not assume a retirement visa, long stay or work permit alone establishes eligibility. Establish the correct route first, then arrange the financial evidence to match it.How the 49% foreign quota works
The Thai government’s foreign condominium ownership guidance also describes the 49% ceiling by area. This matters because units can have very different sizes. A building with many smaller foreign-owned units may have a different quota position from one with fewer large foreign-owned units. For illustration, if the registered total unit area is 10,000 square metres, the general foreign limit is 4,900 square metres. This example explains the calculation; it does not establish availability in a particular building. The condominium juristic person and Land Office must verify the actual position. Ask for current written quota confirmation before committing. An agent’s listing description or a seller’s assurance is useful background, but it should not replace the documents required for registration.Why older condominium law articles can mislead
Some older summaries of the 1999 amendment describe a special route to foreign ownership above 49% in certain locations. The current consolidated Section 19 bis states the general 49% limit. Buyers should not use an old article’s reference to 100% foreign ownership as proof that a new purchase qualifies. If a seller claims a historical exception applies, ask a lawyer to examine the registered title and legal basis with the Land Office. Likewise, a proposal or news headline about a higher quota does not establish your right to register a transfer. Check the law and the building’s records for your transaction.Bank documents for foreign condo buyers
Plan the payment route before sending money. Bangkok Bank’s transfer guidance explains that condo purchase funds can be sent via SWIFT to a Thai baht or foreign currency deposit account. The bank asks senders to state the purpose as purchasing a condominium and to request the documents needed by the Department of Lands. Buyers often refer to this evidence as an FET, or Foreign Exchange Transaction document. Ask your receiving bank which form, certificate or supporting advice it will issue for your transfer. Then confirm with your lawyer that the buyer’s name, payment purpose and documented amount support the intended registration. Avoid assuming that every remittance service or ordinary domestic baht transfer produces suitable evidence. Get confirmation before transferring the purchase funds. Keep the bank records together with your contract and receipts so the payment trail is easy to follow.Thailand Condominium Act transfer checklist
The government’s registration document guidance identifies condominium title documents, identity evidence and additional certificates. For a typical purchase, prepare and check:- The unit title deed and the seller’s authority to transfer it
- Your passport and evidence supporting your ownership eligibility
- The sale agreement and payment records
- Acceptable bank evidence for the funding route you use
- The juristic person’s foreign quota confirmation
- A debt-free certificate for relevant condominium common expenses
- Any required spouse documents, translations or power of attorney
Check the building as carefully as the title
Legal eligibility is only part of a sensible purchase. Review common fees, reserve funds, planned repairs, management records and building rules. Inspect the unit and ask about maintenance issues that could affect your costs after completion. Also ask for a written estimate of transfer costs and an agreement explaining which party pays each item. Judge the property against your intended use, likely running costs and realistic rental prospects. Do not treat foreign freehold availability as a promise of investment returns.Frequently asked questions
Can a foreigner own 100% of one condo unit?
