A Foreign Currency Remittance Form is an official bank document issued by the receiving bank upon the receipt of foreign currency into your bank account in Thailand. You must request a Foreign Currency Remittance Form from your bank when you are remitting funds to Thailand for the purpose of purchasing a condominium, and the document must specify that the remittance is solely for the purpose of purchasing a property/condominium. This is a very important document and you should retain copies so they can be used if you ever sell your property and wish to transfer the monies out of Thailand again. The owner of each condominium is issued with a certificate of unit ownership. The certificate also has a statement saying exactly what percentage of rights over the common areas of the building each owner has.
