Source of Funds Documents for Buying a Condo in Thailand: The Complete 2026 Checklist
Thailand's Anti-Money Laundering Office (AMLO) blocked real estate transactions worth over 12 billion baht in a single year due to inadequate proof of fund origin. For any foreign buyer purchasing a condominium in Thailand, the source-of-funds documentation package is not a formality - it is the legal foundation without which ownership simply cannot be registered.
In 2026, Thai banks, Land Offices, and developers require non-residents to demonstrate a clear, transparent chain: where the money originated, through which bank it traveled, and in what currency it arrived. A single error in one document can delay registration by months or result in an outright refusal.
Quick Answer
- The FET form (Foreign Exchange Transaction Form) is the mandatory document when transferring funds from abroad to purchase a condo under the foreign freehold quota
- The minimum transfer amount to trigger an FET is the equivalent of 50,000 USD (or equivalent in another currency)
- Funds must arrive in Thailand in a foreign currency and be converted into Thai baht by the receiving Thai bank
- The payment purpose field must clearly state 'for purchase of condominium'
- The Land Office requires the FET when registering ownership in a foreigner's name
- SET-listed developers typically also request a 6-month bank statement and proof of legal income
Scenarios and Options
Scenario 1: Direct International Transfer
This is the most common route for international investors. Funds are transferred from an overseas bank account - whether held in Europe, the UAE, Singapore, Georgia, or elsewhere - into a personal Thai bank account. Upon receiving the transfer, the Thai bank issues the FET form (formerly known as Thor Tor 3).
The critical rule: the transfer must arrive in a foreign currency. If the sending bank converts funds into Thai baht before dispatch, the receiving Thai bank will not issue an FET. There is no workaround for this.
For investors transferring from jurisdictions with limited direct SWIFT access to Thai banks, intermediate banking hubs are commonly used. In this case, it is essential to preserve the complete documentation chain: the original bank statement, the transfer confirmation to the intermediate bank, and the final transfer into Thailand. The Land Office will accept the FET issued by the Thai bank, but the developer may request additional supporting explanations.
Scenario 2: Payment from a Thai Bank Account (Resident Income)
If the buyer holds a valid work permit and maintains a Thai bank account funded by locally earned income, the FET is not required. Instead, the Land Office accepts a bank statement confirming available funds, alongside an employment certificate and a tax return (Por Ngor Dor 91). This route is suitable for expatriates earning a Thai salary but does not apply to most non-resident investors.
Scenario 3: Purchase via a Thai Company (Leasehold or Freehold Land)
When acquiring property through a Thai Co., Ltd., source-of-funds documents are submitted in the company's name. Required documents include a director's loan agreement, a corporate bank statement, and an FET issued in the name of the company or its director. The tax implications of this structure are covered separately in our dedicated guide.
Scenario 4: Partial Cash Payment
Some developers in Phuket accept a cash deposit, typically up to 100,000 baht. However, the final payment required to register freehold title in a foreigner's name always requires a valid FET. Attempting to complete an entire transaction in cash is a direct path to registration refusal and potential scrutiny from AMLO.
Comparison Table

|---|---|---|---|---|
| Primary Document | FET from Thai bank | Bank statement plus tax return | FET plus director loan agreement | FET after exchange conversion |
| FET Threshold | Equivalent of 50,000 USD | Not applicable | Equivalent of 50,000 USD | Equivalent of 50,000 USD |
| Transfer Currency | Foreign currency (USD, EUR, GBP, etc.) | Thai baht | Foreign currency | Baht after selling crypto on licensed exchange |
| FET Processing Time | 1 to 3 business days | Not required | 1 to 3 business days | 3 to 7 business days |
| Risk of Refusal | Low if purpose field is correct | Low | Medium (structure scrutiny) | High (not all banks issue FET for crypto proceeds) |
| Additional Documents | Passport, sale and purchase agreement | Work permit, PND 91 | Company incorporation documents | Exchange transaction history |
Main Risks and Mistakes
1. Incorrect payment purpose field. If the remittance purpose states 'living expenses', 'gift', or is left blank, the Thai bank will issue an FET with an incorrect code and the Land Office will reject it. There is no way to amend the purpose after the transfer has been received - the funds must be returned and a new transfer sent with the correct wording.
2. Converting to baht before sending. A common and costly mistake: the buyer instructs their bank to send Thai baht directly. The receiving Thai bank does not record a foreign currency conversion and therefore cannot issue an FET. Always send in a foreign currency.
3. Splitting transfers into many small amounts. Some buyers break the purchase sum into multiple smaller transfers. The Thai bank may decline to issue a single consolidated FET or demand a written explanation for each. Best practice: use one or two transfers covering the full transaction amount.
4. Transfer arriving from a third party. Funds must come from the buyer's own personal account. If the transfer originates from a family member or business partner, a notarized power of attorney and a gift declaration are required. Without these, the Land Office will not accept the FET.
5. Losing the original FET document. The FET is issued as a physical paper original. Copies and scans are not accepted at the Land Office. Losing the original means returning to the bank for a replacement, a process that typically takes 2 to 4 weeks.
6. Mismatch between FET amount and contract price. If the FET states 5,000,000 baht but the sale and purchase agreement states 5,500,000 baht, the Land Office will require a supplementary FET covering the difference.
7. Using unlicensed crypto exchanges. In 2026, Thai banks issue FET documents for proceeds originating from licensed exchanges such as Bitkub and Satang Pro. Funds arriving from unlicensed platforms or peer-to-peer services will not qualify for FET issuance.

FAQ
What is the FET form and why is it required?
The FET (Foreign Exchange Transaction Form) is a document issued by a Thai bank confirming that foreign currency was transferred into Thailand and converted into Thai baht. Without it, the Land Office cannot register freehold condominium ownership in a foreigner's name under the foreign quota.
Can an FET from one Thai bank be used if the transfer was received by a different bank?
No. The FET is issued exclusively by the Thai bank that received and converted the foreign currency. Transferring funds between Thai banks after conversion does not generate a new FET.
Which Thai banks have the most experience handling foreign property purchases?
Bangkok Bank and Kasikornbank (KBank) have the strongest track records with foreign buyers. Bangkok Bank is generally considered the most accommodating for large inbound transfers from non-residents.
Is an FET required for leasehold purchases?
No. The FET is only required to register freehold ownership in a foreigner's name. For a long-term lease (30-year leasehold), the Land Office does not request an FET. However, the developer may still request source-of-funds documentation under their own compliance procedures.
What if the sending bank does not include a remittance purpose?
Provide the receiving Thai bank with a cover letter specifying the purpose of the transfer, the buyer's details, and the property address. Some banks will accept this as a basis for issuing an FET with the correct purpose code.
Does the Land Office accept cryptocurrency directly?
No. Thailand's Land Department does not accept cryptocurrency. The process requires selling crypto on a licensed Thai exchange, withdrawing baht to a Thai bank account, and then obtaining an FET if the original crypto funds came from abroad.
How much does opening a Thai bank account for a condo purchase cost?
Opening an account is free. However, a non-resident without a work permit will typically need a valid non-tourist visa and a recommendation letter from the developer. The process usually takes 1 to 2 business days.
Does the FET have an expiry date?
Formally, the FET does not expire. In practice, however, the Land Office may request a current bank statement if the FET was issued more than 6 months earlier. It is advisable to complete both the transfer and the registration within 3 months of each other.
The most valuable practical advice: begin preparing your financial documentation before signing the reservation agreement. Open a Thai bank account, send a small test transfer, and confirm that your banking chain functions correctly. This approach saves weeks of uncertainty and eliminates the risk of a deal collapsing at the final stage.
