What the 49 percent foreign quota actually means
The Condominium Act caps foreign ownership at 49 percent of the total saleable area of every registered condominium project. The remaining 51 percent must be held by Thai nationals or Thai juristic persons. The quota is measured against saleable area, not unit count, so a single large penthouse counts more than a small studio. When the 49 percent is full, no further foreign freehold sales can be registered in that project until Thai owners sell back to the Thai side of the ledger.
Inside the quota, a foreign buyer holds the unit in freehold, in their own name, with a title deed (chanote) issued by the Land Office. It is real ownership: heritable, sellable, mortgageable, and enforceable against anyone. This is the single most straightforward ownership route open to foreigners in Thailand, and it is the route we recommend for anyone buying a condo in Cha-am or Hua Hin.
Why the quota exists and how it is measured
The Condominium Act (B.E. 2522, as amended) reserves majority Thai ownership of every condominium project as a matter of policy. The juristic office of each building keeps a live register of foreign versus Thai ownership by area. Before any sale to a foreign buyer, the juristic office issues a certificate confirming that the transaction fits inside the remaining foreign quota. Without that certificate, the Land Office will not register the transfer.
In practice this means the quota is verified twice: once by the juristic office when the certificate is issued, and again by the Land Office official on transfer day. A buyer who has not confirmed the quota before signing risks paying a deposit for a unit that legally cannot be transferred to them.
Foreign currency and the FET form
For the Land Office to register a foreign buyer as owner, the full purchase price must have been transferred into Thailand from abroad in foreign currency, then converted to Thai baht inside Thailand. The bank issues a Foreign Exchange Transaction (FET) form, also called a bank credit advice for smaller amounts, that documents the inbound transfer and the purpose (purchase of a condominium unit at a named address). This document is one of the required exhibits at the Land Office and without it the transfer will not be registered in the foreign quota.
The transfer must be in the buyer's name, or clearly earmarked for the buyer, and the FET form should state the correct purpose. Sending Thai baht from a Thai account, or transferring foreign currency that is not properly documented, will fail this test and the Land Office will refuse to register the sale.
Transfer day: how the quota is checked
On transfer day the parties meet at the local Land Office with the juristic office certificate, the FET forms, the title deed, the sale and purchase agreement, and identification. The Land Office official reads the certificate, checks the FET evidence against the purchase price, updates the ownership register, and issues an amended title deed in the buyer's name. Transfer fees, specific business tax where applicable, stamp duty, and withholding tax are settled on the day and are usually split between buyer and seller as agreed in the contract.
What to do before you sign
Ask the juristic office for a written statement of the current foreign quota status in the project, unit by unit if necessary. Ask your bank about the FET form process and the exact reference wording they need on the inbound wire. Instruct a qualified Thai lawyer - independent of the seller and the developer - to run title, quota, and juristic accounts. If any of these three checks cannot be answered cleanly in writing, walk away. For the wider context, start with the buying property in Thailand pillar, and if you are also considering a house, read the leasehold guide and the nominee crackdown guide.
