Bangkok condominium towers, where an off-plan purchase is paid in instalments

The FET when an off-plan condo is paid in instalments: every transfer is its own remittance.

FET, paid in instalments. Every transfer is its own remittance. Brinkman Data brand card.

// Short answer

Paying a developer in stages does not change what the Land Department asks for. It changes how many documents answer it. Every instalment wired from abroad is its own inward foreign-currency remittance, so each one produces its own FET form or credit advice letter, and the file you carry to transfer is a run of documents rather than one. This page is only about that difference. The document itself, the bank workflow and the wire wording are covered in the general guide, linked in the first section below.

Statutory wording as of September 2026, from the Office of the Council of State's consolidated Thai text of the Condominium Act B.E. 2522. Bank thresholds and document handling are banking practice, not statute, and they can differ by bank and by branch. Confirm your own instalment sequence with the receiving Thai bank in writing before the first payment leaves.

Does an off-plan condo bought in instalments still need a FET?

Yes. The benchmark is the amount, not the number of transfers. Section 19 ter asks for evidence of foreign currency brought into the Kingdom in an amount not less than the price of the unit. It sets no limit on how many remittances.

Start with the general guide. Everything about the document itself, how the receiving bank issues it, the wire wording and the USD 50,000 line is set out in the Thailand FET certificate guide, and this page assumes you have read it. What follows is only what changes when the price is paid in stages.

Read the wording carefully, because it is the whole basis for an instalment purchase working at all. The Act never says FET. It asks for evidence. The FET form, and the credit advice letter below the bank's threshold, are what a Bank of Thailand authorised bank issues to record an inward foreign-currency transfer, so they are the evidence.

What the instalment structure adds is arithmetic and bookkeeping. The total evidenced has to clear the price of that specific unit. Spread over eight payments across two years, that means eight documents that add up, in the buyer's name, with the purpose stated, all still in your hands on transfer day.

The statutory chain behind it: Section 19 of the Condominium Act, explained.

Is each off-plan instalment its own foreign exchange transaction?

Yes. The receiving Thai bank records each inward transfer separately, so each instalment is documented on its own. One payment does not roll into the next. A twelve-payment schedule produces twelve records, and you collect each one as it happens.

This is the point that catches people out, and it is a bookkeeping point rather than a legal one. A single-payment purchase produces one document and one collection trip to the bank. An instalment purchase produces the same trip every time a payment lands, for as long as the build runs.

Treat each instalment as a complete mini transaction with four questions attached:

Answer those four on the day, every time, and the file assembles itself. Leave them and you are reconstructing a two-year paper trail from bank statements at the point when you can least afford the delay.

What does a buyer collect and keep after each instalment?

The bank's hard-copy record of that transfer, collected at the time rather than years later. Digital copies are not what the Land Department reads. On an instalment purchase the oldest document in the file is the one most likely to be missing.

The FET form and the credit advice letter are issued on paper, with the bank's stamps. A single-payment buyer collects one document a fortnight before transfer. An off-plan buyer is holding a document from a payment made before the building had walls. Storage is therefore part of the process, not an afterthought.

What to hold per instalment:

Hold thisWhy it matters at transfer
The FET form or credit advice letter, original hard copy with bank stampsIt is the evidence Section 19 ter asks for, for that slice of the price
A second original, kept outside ThailandA replacement can be requested from the issuing bank, but it takes time you may not have
The outgoing wire instruction from your overseas bankIt shows the remitter name, the currency and the purpose wording you asked for
The developer's receipt for that instalment, naming the unitIt ties the remittance to the unit rather than to a general payment
A one-line running total in your own currency and in bahtThe benchmark is the price of the unit, so you need to know where the total stands at any point

You will want the remittance evidence again on the way out, when sale proceeds are repatriated, so none of this stops being useful at transfer. The rest of the closing-day file sits in the Thailand condo due diligence checklist.

How do you keep the remitter, the purpose and the recipient consistent across a long build?

By writing the three fields down once and reusing them without edits. The remitter name should match the passport name going on the title. The purpose should name the unit and the project. The recipient should be the account named in your contract.

Section 19 quater conditions registration on the Section 19 ter evidence being satisfied. So the question at the counter is not whether the money arrived. It is whether the money that arrived is documented as the buyer's money, for this unit. A run of instalments gives that link more chances to break than a single wire does.

The places it drifts on a long build, all of them checkable in advance:

Write the exact remitter string, the exact purpose sentence and the exact recipient details into one note the day the contract is signed. Every later instalment is then a copy and paste, which is the point.

The evidence is read at transfer. What about an instalment paid three years earlier?

Ask early, in writing, through Thai property counsel. The document records a transfer that happened and does not lapse, but the Land Office reads the file on registration day. An off-plan purchase makes that gap years wide, so settle it before the schedule runs.

On a resale, the gap between the wire and the registration is measured in weeks. On an off-plan purchase it is measured in years, by design. That is the difference this page exists for. Treat it as a scheduled task rather than a hope:

  1. Before the payment schedule is locked, have counsel ask the Land Office that will register the unit how a set of instalment remittances spread over the build period should be presented, and what it wants to see alongside them.
  2. Get the answer in writing and keep it with the file.
  3. Ask again when a transfer date exists, because staff, practice and the file all move over a multi-year build.

One more thing moves over that period: the price. Section 19 ter measures the evidence against the price of the unit to be purchased. If the final price rises after a variation, an extras package or a final area measurement, the remitted total has to still clear it. Check the running total against the final contract figure before the last instalment, while there is still a payment left to adjust.

And the remittance evidence is only one of the gates on transfer day. The foreign quota letter and the debt-free certificate are separate documents answering separate questions, each with its own freshness window. Clearing one says nothing about the others.

Can the building's foreign quota change between the first instalment and completion?

Yes. Section 19 bis caps foreign holdings at forty-nine percent of the area of all the units, and Section 19 quater has the official verify that ratio at registration, counting the transferee. The denominator is fixed at the building's registration. The numerator moves with every transfer.

This rides alongside the money question and is tested on the same day. A resale buyer checks the ratio, then registers a few weeks later. An off-plan buyer is registering at the end of a build, when a large number of units in the same building are registering too.

What an instalment buyer can actually do about it:

The arithmetic, the freshness windows and what the letter has to state, line by line: the foreign quota letter, explained. The statutory side: Section 19, 19 bis, 19 ter and 19 quater.

Frequently Asked Questions

Do I need a separate FET for every off-plan instalment?
Expect one document per inward remittance, because the receiving bank records each transfer separately. The Act's benchmark is the amount, not the document count: the evidence has to add up to not less than the price of the unit. Collect each document as the payment lands rather than reconstructing the set at the end.
My off-plan instalments are each under USD 50,000. What changes?
The threshold is applied per single inward transfer, so a schedule of small payments can produce a run of credit advice letters instead of one FET form. Arrange it with the receiving branch in writing before the first instalment, because the arrangement has to hold for the length of the build, not for one afternoon.
Does a payment made from money already inside Thailand count toward the Section 19 ter amount?
It produces no inward remittance, so it produces no record of foreign currency arriving. Section 19 ter asks for evidence of foreign currency brought into the Kingdom in an amount not less than the price of the unit. Any instalment paid from funds already in the country leaves a gap in that total. Plan each stage as a transfer from abroad.
What if the developer's receiving bank account changes during the build?
Treat it as a document question before it is a payment question. Get the change confirmed in writing by the party named in your contract, keep that confirmation with the file, and make sure your counsel has seen it before the next wire leaves. A recipient that does not match the contract is the kind of mismatch you want to explain in advance, not on registration day.
Is there a foreign quota letter while the building is still under construction?
The letter comes from the condominium's juristic person, which a registered condominium has. So on a building still being built, the first question for your counsel is when the condominium is expected to be registered and from what date a letter can be issued. Until then there is no letter to read, and the ratio that decides your registration is the one at the end.
My contract price rose after a final area measurement. Does the remitted total still work?
Check it before the last instalment, while a payment is still available to adjust. Section 19 ter measures the evidence against the price of the unit to be purchased, so a total that cleared the original figure may not clear a revised one. Keep a running total against the current contract price rather than against the price you first agreed.
