Buying Off-Plan in Thailand: What Actually Protects You

Why does off-plan fail differently from any other purchase?

Off-plan means unbuilt: you commit to a property on paper, and your money moves months or years before the asset exists. The two usual failure points are the building permit and the mother title — whether the permit exists at all, and whether the subdivision that produces your plot is complete.

Both are verifiable records, not opinions, and both can be checked before any payment — as can the developer's corporate standing, the encumbrances on the parent land, and the environmental approval where the project needs one. An off-plan purchase is a promise about the future; the records say who is making that promise, and on what land.

Does escrow protect off-plan buyers in Thailand?

Thailand has an escrow law — the Escrow Act B.E. 2551 (2008) — under which a licensed escrow agent, in practice a bank or financial institution approved by the Ministry of Finance, holds the buyer's instalments until agreed conditions are met. It is entirely voluntary: no law obliges a developer to offer it, and most do not. In the standard Thai off-plan purchase, every instalment goes directly to the developer and is spent as construction finance.

The contrast with France deserves stating plainly, because French buyers often assume an equivalent exists here. A French VEFA sale carries a mandatory completion guarantee — the garantie financière d'achèvement — under which a bank or insurer must fund completion if the developer fails. Thailand has no equivalent. A buyer can ask for escrow; the default position, though, is that money paid for unbuilt concrete is protected by nothing except the checks made, and the terms negotiated, before signing.

Which developer checks are verifiable records?

'Reputable developer' is not a record. What can actually be pulled and read, before any payment:

Zoning and terrain rules sit behind all five. The city plan colours land by use, and environmental zones add constraints: on Koh Samui, Zone 2 orange allows residential building with a height cap commonly set at 12 metres. Samui and Phuket also restrict construction above certain gradients and elevations. Land can be legally owned and legally unbuildable — which, for an off-plan project, is the difference between late and never.

The five records, and what each one answers:

• The mother title and its encumbrances — the parent parcel the project subdivides from, searched at the Land Office. A mortgage registered on it usually means the land itself finances the construction; what happens to that mortgage before your transfer belongs in the contract, not in assumptions.
• The subdivision status — dividing land into ten or more plots for sale requires an allocation licence under the Land Allocation Act B.E. 2543 (2000). Off-plan villas are often sold before subdivision completes; where the plot stands in that process is checkable.
• The building permit — issued by the municipality, the Tessaban. For off-plan, the question is whether it exists at all; 'it's coming' is a red flag.
• The environmental approval — a condominium project of 80 units or more, or 4,000 m² or more of usable area, needs an approved environmental impact assessment (EIA) before construction. A project selling units while its EIA is pending is selling something it cannot yet legally build.
• The developer's corporate standing — the company affidavit and shareholder list at the Department of Business Development: who the company is, its registered capital, and whether the entity selling is the entity that owns the land.

What should staged payments be tied to?

Off-plan purchases are paid in stages — a reservation, a payment at contract signing, instalments through construction, and a balance at transfer. The schedule that protects the buyer ties each instalment to a verifiable construction milestone — foundation complete, structure topped out, unit closed in — not to calendar dates, which fall due whether or not anything was built.

Two more facts belong in the schedule's design. Absent escrow, every instalment is an unsecured advance to the developer, so the share of the price left to the transfer date is the buyer's main leverage. And a foreign condo buyer's funds must arrive from abroad in foreign currency, with the bank evidence to show it — the FET form — because that evidence is required to register foreign freehold ownership at transfer.

What rules govern off-plan condo contracts?

For condominiums, the contract itself is regulated. The Condominium Act amendment (No. 4) B.E. 2551 (2008) added two protections aimed squarely at off-plan sales. Under section 6/1, the developer's advertising — brochures, renderings, promised facilities — is deemed part of the sale contract, and a contradiction between the two is construed in the buyer's favour. Under section 6/2, the contract must follow the standard form prescribed by ministerial regulation, any term less favourable to the buyer than that form is unenforceable, and a developer who ignores the form faces a fine of up to 100,000 baht.

Off-plan villas enjoy less of this. A house in a licensed allocation project falls under the Land Allocation Act's own contract controls; a villa project structured outside allocation licensing rests largely on whatever the contract says — which is why, for villas, the contract review and the record checks above carry more of the weight.

What actually happens when a project stalls?

Honestly: the buyer becomes a creditor. A stalled project leaves the buyer contract remedies — rescission for missed deadlines, refund claims, the late-transfer terms of the standard condo form — and every one of them is a claim against the developer, worth what the developer can pay. If the developer is insolvent, instalments paid without escrow rank as unsecured debt, behind the bank whose mortgage is registered on the mother title.

That is the structural reason the checks in this guide happen before signing rather than after: once the money has moved, the leverage has moved with it. Delay is common and usually survivable; what the records screen for is the project that cannot legally or financially be finished at all.

What does a structured verification check before any payment?

Everything above is document work, and it is what a structured verification does: pull the mother title and its encumbrances at the Land Office, confirm the subdivision status and the allocation licence, sight the building permit and the EIA approval where one is required, read the developer's corporate file, and put the payment schedule next to what the records support. Each finding names its source document, its issuing office and who verified it.

Off-plan and land are standard tiers in Suradeed's grid — not scoped work. A villa or plot with a straightforward structure is C2 fixed-price work: €1,590 (THB 62,010), delivered in 10 business days from confirmed payment. What gets scoped is a structure nobody has established yet — a company holding, an offshore layer, a title chain the documents have not settled: those dossiers are quoted by the partner firm after review, at a price agreed before any work starts.

What is Suradeed, and what is it not?

Suradeed is not a law firm and gives no legal advice. Every legal finding and recommendation in a verification certificate is produced and signed by a licensed Thai law firm, which is responsible for it. Suradeed defines the verification protocol, coordinates the work, controls its quality and delivers the result.

The checkout shows one quoted price: it includes the partner firm's fee, which Suradeed collects as payment agent for the firm, and Suradeed's platform and coordination fee. Your invoice records both components separately. Suradeed accepts no commission or referral benefit from any seller, developer, agent or broker — independence is contractual, not a policy statement. On an off-plan purchase that matters twice over: most advice a buyer finds is written by the businesses selling the projects.
