Thailand FET Certificate Guide: The Single Document That Enables Foreign Freehold

The Thailand FET certificate (Foreign Exchange Transaction form, historically called Thor Tor 3) is the document that converts a foreign-currency wire transfer into legal proof your purchase funds came from abroad — and therefore into the right to register a condominium unit as foreign freehold at the Land Department. No FET, no freehold. It is the single point of procedural failure most likely to delay a Chiang Mai or Bangkok closing by weeks. This guide walks through the legal basis, the bank workflow, the exact wire wording, the USD 50,000 threshold rule, and the trap most foreign buyers do not see coming.

What the Thailand FET Certificate Is, Legally

The Foreign Exchange Transaction form is an official document issued by a Bank of Thailand-authorized commercial bank, recording the receipt of foreign currency into Thailand and its conversion into Thai baht. It operates under the Bank of Thailand's Foreign Exchange Regulations and serves as the legal proof of inward foreign-currency remittance.

The Land Department requires this proof at the moment of foreign-freehold title transfer because the Condominium Act requires that the purchase funds for a foreign freehold unit must originate from outside Thailand in foreign currency. The FET is the audit trail. Without it, the Land Office cannot — and will not — register the unit to a foreign buyer on freehold basis.

There is one threshold rule. For a single inward transfer of USD 50,000 or equivalent or more, the receiving Thai bank automatically issues a FET form. For transfers below USD 50,000, the bank issues an alternative document called a credit advice letter (sometimes called a bank confirmation letter). Both documents are accepted by the Land Department for the same purpose — registering foreign freehold title — but the procedural details differ.

The Bank Workflow: How the FET Actually Gets Issued

The Thailand FET certificate is issued by the receiving bank in Thailand, not the sending bank in your home country. This is the structural point most foreign buyers miss.

The workflow:

You open a Thai bank account. This is not strictly required for the FET itself — the funds can be received into any Thai bank account, including the seller's bank account or your lawyer's escrow account — but most foreign buyers open a personal Thai account at Bangkok Bank, Kasikornbank, or SCB before closing. It simplifies all subsequent transactions (utilities, juristic fees, taxes).

2. You initiate an international wire from your overseas bank account to the receiving Thai bank account, in foreign currency (USD, EUR, GBP, AUD, etc. — not THB sent from abroad). The wire must include very specific reference information: - Sender (remitter) name must exactly match your passport name - Purpose of remittance must state "for purchase of condominium unit [unit number] in [project name], Chiang Mai" (or applicable location) - Source of funds disclosure if the sending bank requests it

The Thai bank receives the foreign currency, converts it to THB at the prevailing rate, and credits the recipient account. At this point, if the inward transfer is USD 50,000 or higher, the bank automatically prepares the FET form. If below, the bank prepares the credit advice letter.

You (or your lawyer) collect the FET or credit advice from the bank. This typically requires going in person to the bank branch with your passport. The document is issued in hard copy, with bank stamps. Digital copies are not accepted at the Land Department.

You bring the FET or credit advice to the Land Department on closing day, along with the foreign quota letter, the Chanote, the SPA, and your passport. The Land Office officer reviews and registers the foreign freehold transfer.

Total bank-side processing time: typically 3-7 business days from wire arrival to FET issuance. Add wire transit time of 2-5 business days. Build a minimum 14-day buffer between wire initiation and the closing date.

The USD 50,000 Threshold: When to Split, When Not to Split

The Thailand FET certificate is automatically issued for inward transfers of USD 50,000 or higher. For transfers below this threshold, a credit advice letter performs the same legal function.

A common question: should I split my transfer to stay below USD 50,000? The answer is almost always no. Splitting creates more paperwork, not less, and the credit advice letter route involves more bank-side discretion (some Thai bank branches are slower or less familiar with issuing credit advice for property purposes). A single FET-eligible transfer is cleaner, faster, and less prone to procedural error.

If your purchase price is below USD 50,000 (rare for Chiang Mai but possible for very small units), the credit advice route is your only option. In that case, get the bank's written confirmation that they will issue a property-purchase credit advice letter before you initiate the wire. Some smaller branches are unfamiliar with the process.

If your purchase price is above USD 50,000 (the typical case), wire the full amount in a single transfer. One FET certificate covering the full purchase price is what the Land Department wants to see.

Read the Full Methodology Before Initiating the Wire

The Thailand FET certificate is procedural. The 5-step methodology on the site is structural — it walks through the FET timing, the wire wording, the threshold rules, and how the FET fits into the broader Chiang Mai closing sequence. Read it before initiating the wire. The cost of a delayed FET is measured in canceled closings and forfeited deposits, not in late fees.

Case Study: The FET Timing Trap

When I closed on the 82m² unit at 2.15M THB (roughly USD 60,000 at the prevailing rate), I initiated the wire from my European bank 12 days before closing. The wire landed in my Thai bank account on day 8. The bank required 4 business days to issue the FET. I collected the FET in hard copy on day 4 — the day before closing.

That was tight. If the wire had been delayed by 2 days (common for international SWIFT transfers around holidays or weekends), the FET would not have been ready, and the closing would have been postponed. A postponed Land Department closing in Thailand is not rescheduled for the next day — it goes to the next available slot, which is often 5-10 business days out. The seller had a clause in the SPA that allowed them to cancel and retain the deposit if closing slipped past a specific date. I cleared it by 18 hours.

The Thailand FET certificate timing is the most-overlooked procedural risk in foreign condo purchases. Build a 14-day buffer minimum between wire initiation and closing date. 21 days is safer. Anything tighter and you are gambling on SWIFT transit times you do not control.

Practical Guidance: Pre-Wire Checklist

Before you initiate the international wire that will generate your Thailand FET certificate, verify all six of the following:

Sender name on the wire instruction exactly matches your passport name (full name, no abbreviations, no missing middle names).
Recipient name on the wire instruction exactly matches the Thai bank account holder name (your name if you have a Thai account, or the seller's/escrow agent's name if you do not).
Purpose of remittance field clearly states "purchase of condominium unit [unit number] in [project name]." Vague purposes like "investment" or "personal" can trigger compliance holds at the receiving bank.
Currency is a major foreign currency (USD, EUR, GBP, JPY, AUD, CHF, SGD). Do not send THB from abroad — defeats the foreign-currency-origin requirement.
Amount covers the full purchase price plus a small buffer (1-2%) for exchange rate slippage, transfer fees, and unforeseen closing-table adjustments. Underwiring is fixable but slow.
Timing allows minimum 14 days between wire initiation and Land Department closing date.

Get all six right and the FET issues in the routine course of business.

Frequently Asked Questions

What is the Thailand FET certificate used for?

The FET certificate is the legal proof that the purchase funds for a foreign-freehold condominium unit came from outside Thailand in foreign currency. It is required by the Land Department for foreign freehold title registration.

What is the difference between FET and credit advice letter?

The FET is issued automatically for inward transfers of USD 50,000 or higher. The credit advice letter performs the same legal function for transfers below that threshold. Both are accepted by the Land Department.

Can I use Wise or other money-transfer services for the FET?

Wise transfers can support a property purchase, but the receiving Thai bank still issues the FET based on the foreign-currency inflow it processes. The mechanics depend on how the Wise transfer is structured at the receiving end — confirm with your Thai bank in advance whether the specific Wise route will trigger automatic FET issuance.

Do I need a Thai bank account to get a FET?

Not strictly. The FET is issued based on the receiving bank's record of the foreign-currency inflow, regardless of whose account receives it. But having a personal Thai bank account simplifies the workflow and is recommended for most foreign buyers.

What happens if I lose the original FET certificate?

The issuing Thai bank can issue a certified replacement, but the process takes time. Always keep two original copies — one in Thailand, one offshore. You will need the FET at exit when repatriating sale proceeds.

Does the FET certificate expire?

The FET certificate itself does not expire as a document of record. But the Land Department typically wants a FET dated within a reasonable window of the closing (months, not years). For a FET issued well in advance, confirm with the Land Office in advance that the date is still acceptable.

Can the FET be used for multiple condo purchases?

A single FET corresponds to a specific foreign-currency inflow and a specific purpose. If you are purchasing multiple units, you should generally have a separate FET (or credit advice) per unit, matched to that unit's purchase price.
