How to Verify a Thai Condo’s Foreign Ownership Quota

What the foreign ownership quota measures

The ordinary limit in Section 19 bis of Thailand’s Condominium Act is 49% of the total area of all units in the registered condominium, measured by the statutory registration basis. It is not 49% of the number of apartments, sale proceeds or common land.

Read the Department of Lands’ hosted Act, Sections 19 bis–19 quater. Historic or unusual title claims require specific legal and Land Office confirmation; do not use an old exception or a proposed policy change as your purchase assumption.

This checklist concerns an existing, registered condominium. For off-plan property, do not treat a developer’s projected allocation as evidence of a completed condominium register.

For ownership routes, funds evidence and the broader purchase sequence, start with Buying Property in Thailand.

Why a “foreign quota available” listing is not enough

The seller’s marketing description does not establish the registered area, current foreign-held area or whether your proposed acquisition can be registered.

The government transfer-document checklist lists two different condominium documents: a debt-free certificate and the juristic person’s certification of foreign ownership within the area limit. One is not a substitute for the other.

How to verify the quota before buying

1. Identify the registered condominium and unit

Get the registered condominium name, unit title details, recorded area and seller identity. Match them to the sale contract. A project brand or development containing several buildings is not enough to establish the relevant registration.

Ask an independent Thai property lawyer to establish the registration boundary and check the title, seller’s authority and any encumbrances separately. The quota review does not establish clean title.

2. Request the juristic person’s quota certificate

Contact the condominium juristic person through independently checked management details. Request its current certification for the contemplated transfer, not an agent-created spreadsheet or a screenshot from an earlier sale.

Ask management to identify the registered total unit area, the area already held by foreign owners and how the proposed transfer affects the ratio. Ask who signs the document and which original the Land Office requires.

The Department of Lands regulation, clauses 5–6 requires the foreign-holder information and area ratio to be considered with the transferee’s evidence. A certificate alone cannot cure a separate eligibility problem.

3. Check area, not unit count

Ask for the calculation behind the certification. As a simple arithmetic illustration, 49% of 10,000 m² is 4,900 m². If foreign-held area is 4,850 m², adding a previously Thai-held 60 m² unit would reach 4,910 m² and exceed that ordinary ceiling.

Those are invented figures, not a quota certificate. A foreign-to-foreign resale may affect the ratio differently; do not add the same unit twice. Have management and the Land Office assess the actual ownership before and after the transfer.

4. Keep the other purchase checks separate

• Debt-free certificate: obtain the required condominium clearance document; review common charges and other agreed liabilities independently.
• Title: confirm the seller can transfer the stated unit and resolve mortgages or other registered restrictions.
• Funds: agree with your receiving bank and the Land Office which documents establish your acquisition route before remitting money.

Use the capital-transfer evidence guide to organize the money trail. Do not assume every foreign purchaser has identical funds-evidence requirements.

5. Confirm the registration package with the Land Office

Have your lawyer or authorized representative confirm the competent Land Office’s current document requirements for this unit and buyer. Ask whether the certificate, signatory, area calculation and supporting evidence are acceptable.

The official registration sequence includes an officer’s document examination and registration. Advance enquiries and a seller’s assurance are not the completed title transfer.

6. Recheck before completion and retain the evidence

Agree who obtains refreshed documents if completion is delayed or other transfers occur. Do not assume a universal certificate expiry period, processing time, quota-reservation system or guaranteed fee: confirm these for your building and transaction.

Keep the quota and debt-clearance documents, checked title records, bank evidence, signed contract and registration receipt together. If the ordinary quota cannot accommodate the purchase, pause for independent advice rather than accept a nominal-owner workaround.

General buyer due diligence, not a title opinion or live quota search. The Thai statutory text and the competent Land Office govern; obtain independent advice before committing funds.
