Thailand's 49% Foreign Condo Quota Explained: What Buyers Must Check

Legal 7 min read By Nestenn Thailand Research Team Published August 25, 2026

A foreign buyer can own a qualifying condominium unit in Thailand in freehold, registered in the buyer's own name, when the legal conditions are met. The best-known condition is the foreign ownership quota: eligible foreign persons and foreign entities may collectively own no more than 49% of the total area of all units in a particular registered condominium.

The percentage is often described too loosely. It is not a limit of 49% of the number of apartments. It does not mean a foreign buyer owns only 49% of one unit. It is a building-level test based on unit area. A qualifying buyer can own 100% of the selected unit, provided the building still has enough foreign quota available and the transfer satisfies the other legal and funding requirements.

What does the 49% foreign condo quota measure?

Section 19 bis of Thailand's Condominium Act sets the ceiling by reference to the total area of all units in each condominium. Common property, such as the lobby, corridors, pool, gym, and the land held for the condominium, is not counted as separate unit area for this calculation.

Consider a registered condominium with 10,000 square metres of total unit area. Foreign owners covered by the law may collectively hold up to 4,900 square metres. If 4,850 square metres are already in foreign ownership, a 70-square-metre unit cannot be transferred to another foreign buyer in freehold unless sufficient quota becomes available before registration.

Market reports on the national share of condominium transfers to foreign buyers answer a different question. They describe transaction activity across a market or period. They do not prove that a specific building has quota available.

Confirm that the property is a registered condominium

The word "condo" in a listing is not enough. Foreign freehold ownership depends on the building being registered as a condominium under the Condominium Act and on the unit having a condominium unit title deed.

This distinction matters for serviced apartments, residence schemes, hotel-style products, and projects that are still waiting for registration. A buyer may be offered a lease or another contractual right in such a project, but that is not the same as registered freehold title to a condominium unit.

Before paying a reservation fee, ask for the building's condominium registration details, a copy of the unit title deed for a resale, and a clear written statement of the ownership form being offered. For an off-plan purchase, the contract should state what happens if the project or unit cannot be transferred in the promised ownership form.

How quota availability is verified

The condominium juristic person keeps records of unit ownership and the foreign ownership ratio. For a transfer to a foreign buyer, the manager or authorized representative provides the documentation required for the Land Office, including confirmation relevant to the foreign ownership proportion. The Land Office reviews the transfer documents and will not register a foreign freehold transfer that would breach the statutory ceiling.

A buyer should not rely only on an agent's message, a brochure label, or an old quota letter. Use this sequence:

1. Confirm the exact unit number and registered area.
2. Obtain current quota information directly from the condominium juristic person.
3. Ask whether any pending transfers could affect availability before your transfer date.
4. Make the sale agreement conditional on lawful foreign freehold registration if that is the agreed ownership form.
5. State clearly what happens to the reservation fee and deposit if foreign freehold registration is not possible.
6. Recheck the quota shortly before the Land Office appointment.

The quota letter is important, but it is not a substitute for full due diligence. The unit title, seller's authority, mortgages, court orders, unpaid common charges, building records, and contract terms still require review.

Funding evidence must be planned before transfer

For many foreign buyers, eligibility under Section 19 depends on bringing foreign currency into Thailand or using another funding route recognized by the Act. The buyer must present evidence that matches the chosen route. For the usual inbound foreign-currency route, the evidence should cover at least the unit's sale price.

The practical documents can vary with the amount, bank, account structure, currency route, and the buyer's status. They may include a Foreign Exchange Transaction form, credit advice, bank confirmation, or evidence relating to a qualifying non-resident or foreign currency account. The legal test and the bank's document name should not be treated as interchangeable.

Speak to the receiving bank and an independent Thai lawyer before sending the purchase money. Confirm the buyer's name, sender or beneficiary details, remittance purpose, currency, receiving account, and wording the bank will record. A transfer made from the wrong account or with unclear payment details can be difficult to correct at the Land Office counter.

Keep the complete bank file after the purchase. It may also be relevant when documenting the transaction for a future sale and repatriation of funds.

Off-plan, resale, and full-quota situations

Quota risk appears differently in each transaction.

Off-plan purchase

A developer may allocate units intended for foreign freehold, but the legal position must still work at registration. The sale agreement should identify the promised ownership form, the payment route, the expected transfer documents, and the remedy if foreign freehold cannot be delivered. A marketing allocation is not a registered title.

Resale purchase

Check the current title holder and the building's quota position. A unit owned by a Thai person is not permanently locked into a "Thai quota" category. It may be transferred to an eligible foreign buyer if sufficient foreign quota exists and the other requirements are met. A unit transferred from foreign ownership to a Thai buyer can release foreign quota area.

Building already at the limit

Do not accept a substitute structure without understanding it. The realistic choices may be to wait for quota to become available, select another qualifying unit or building, or consider a lease priced and reviewed as a lease. A lease does not provide freehold title, and a Thai nominee company is not a lawful shortcut.

Five checks before paying a deposit

Use this decision gate before committing substantial funds:

• Ownership form: Is the offer genuinely foreign freehold, or is it leasehold or another contractual arrangement?
• Registered status: Is the building a registered condominium, and does the unit have or qualify for a condominium title deed?
• Current quota: Has the juristic person confirmed enough foreign quota for this unit's area?
• Funding route: Can the buyer produce the evidence required for the chosen eligibility route?
• Contract protection: Does the agreement provide a clear refund or remedy if the promised foreign freehold transfer cannot be registered?

The answer to all five should be clear before the deposit becomes non-refundable.
