How Contracts Work When Buying Property in Thailand: Reservation, SPA and Transfer
Thailand property contracts guide: reservation agreement (non-binding, $2,500–5,000), SPA (binding main contract), and transfer documents — plus red flags to watch for.
How Contracts Work When Buying Property in Thailand: Reservation, SPA and Transfer
Thai property purchases typically move through three contract layers: a reservation agreement (often partially binding commercially, with deposits commonly around $2,500–$5,000 USD), a Sale and Purchase Agreement (SPA) as the binding commercial backbone, and Land Department transfer documents that actually change ownership. If you only sign a reservation and wire money without SPA discipline, you may not have what you think you bought—you have a receipt and hope.
Contracts are not “paperwork.” They are the written version of who bears risk when reality hits—delays, defects, currency moves, and human disagreement.

Stage 1: Reservation agreement — what it locks (and what it does not)
A reservation usually takes a unit off the market for a short window (commonly 7–14 days) while your lawyer reviews the SPA—treat it as a sprint, not a vacation. Deposits are often non-refundable if you walk away without a contractual excuse.
| Element | Typical intent |
|---|---|
| Deposit | $2,500–$5,000 USD (varies) |
| Exclusivity | Unit held briefly |
| Next step | SPA drafting |
Stage 2: SPA — the contract that governs money and penalties
The SPA sets price, payment schedule, completion/transfer obligations, defaults, and dispute resolution—this is where “developer-friendly” templates hide. Key clauses foreigners miss include developer delay penalties, assignment rights, defect remedies, and what happens if foreign quota is unavailable.
| SPA clause | Why it matters |
|---|---|
| Completion date | Tie to measurable milestones |
| Penalties | Symmetry: buyer vs seller |
| Assignment | Resale flexibility |
| Dispute resolution | Arbitration vs courts |
Stage 3: Transfer documents — Land Department reality
Transfer documents finalize registration at the Land Department—your SPA can be “perfect” and you still fail if funds, title, and quota do not align on transfer day. Think of transfer as a separate gate.
Red flags: reservation traps
No cooling-off clarity, vague refund terms, and pressure to skip legal review are classic warning signs. If a seller insists on “standard” language, you can still insist on independent counsel.
Red flags: SPA traps
One-sided penalty clauses, unlimited developer extensions, and missing assignment rights can turn a “good investment” into a cage. If the SPA punishes only the buyer, negotiate or walk.
Red flags: transfer traps
Mismatch between SPA price and declared transfer values can create tax and legal exposure—never treat tax declarations as “someone else’s problem.” Your lawyer coordinates lawful structuring.
| Transfer issue | Why foreigners get hurt |
|---|---|
| Undisclosed mortgage | Blocks release |
| Quota failure | Cannot register freehold |
| Name mismatch | Officer rejection |
Make the SPA match your risk

Off-plan vs resale: how contracts differ
Off-plan SPAs include construction milestones, defects, and delay remedies; resale SPAs focus on clean title transfer and condition at handover. Do not reuse mental models across these two worlds.
Resale add-ons you may need
Resale purchases may require additional schedules for furniture inclusion, meter readings, and juristic office clearance letters—your lawyer lists what the Land Department and building require beyond the SPA headline price.
| Resale topic | Why it shows up |
|---|---|
| Furniture package | Avoid “included” fights |
| Service fees | Unpaid CAM can block handover |
| Keys / access cards | Practical possession |
If your SPA is shorter than your group chat with the seller, you are under-documented, overexposed, and dangerously informal for the price you pay.
Assignment and resale: what you want if you exit early
If you plan to flip or assign, your SPA should explicitly permit assignment (or define the conditions). “Locked” contracts can destroy liquidity in soft markets.
Dispute resolution: arbitration clauses and practical reality
Many contracts specify arbitration or Thai courts—understand what that means for cost and timeline before you sign. Cheap disputes can still be expensive internationally.
Exhibits and schedules: the real deal is often in the attachments
Floor plans, payment schedules, specifications, and unit schedules are often incorporated by reference—if an exhibit is missing or unsigned, you may not have the product you think you purchased. Demand a complete exhibit pack before you pay non-refundable tranches.
Practical checklist before signing SPA
Confirm title, quota, payment schedule alignment with bank transfers, and defect inspection rights—then sign. Signing first and “fixing later” is expensive.
Payment schedules: why “installments” are legally sensitive
Installment schedules must match what banks can document for registration and what the developer can deliver—misaligned schedules create defaults that are legally “your fault” even when the project stalls. If you pay ahead of verifiable milestones, you weaken leverage.
| Payment event | What to tie it to |
|---|---|
| Deposit | Reservation / contract execution |
| Construction | Third-party inspections where possible |
| Transfer | Land Department readiness |
Representations and warranties: what sellers promise vs what you verify
SPAs often include seller representations about title and encumbrances—verify them with independent diligence rather than trusting adjectives. “Free and clear” is a claim; a title extract is evidence.
Defect periods and snagging: condos vs villas
Condos often include defect liability periods; villas may include construction warranties—define what “defect” means and how remediation works. Without a process, you get arguments.
Force majeure: not a blank check for developers
Force majeure clauses should be narrowly defined—broad “anything happens” language can excuse delays indefinitely. If you see unlimited extensions, push back.
Personal vs company buyer: contracting entity matters
If you change buyer entity mid-deal, you may trigger assignment fees, tax changes, or quota re-validation—decide early. Last-minute changes are where closings die.
Escrow reality: what Thailand deals use instead
Escrow is not always structured like US/EU transactions—often milestones, lawyer-held funds, or developer payment schedules substitute—understand what protects you if the seller fails. “Trust me” is not escrow.
Currency and FX: matching SPA to bank documentation
If your SPA is in THB but you think in USD, build a conversion rule and align it with how your bank issues FET documentation for freehold registration. FX movement can change your effective price and your registration pathway.
Taxes and fees: who pays what (and why it must be explicit)
Transfer fees, taxes, and duties are frequently negotiable—but only if the SPA says so. Default assumptions cause closing-day fights.
| Fee / tax theme | Typical negotiation point |
|---|---|
| Transfer fee | Split ratios |
| Stamp duty / specific business tax | Seller vs buyer facts |
| Withholding tax | Often seller-side but confirm |
Default clauses: what happens when you stop paying
SPAs define seller remedies—sometimes forfeiture of payments—treat installments as legally serious. If you cannot service the schedule, do not sign the schedule.
What a clean contract stack looks like in your email folder
Reservation + signed SPA + annexes + title extracts + payment receipts + lawyer closing memo = a coherent story. Messy folders correlate with messy disputes.

A Sale and Purchase Agreement is typically the main binding contract that sets price, payment schedule, and transfer obligations between buyer and seller.
A lawyer review is strongly recommended because SPAs contain penalty clauses and risk allocation that materially affect your investment.
Land Department registration and transfer documents are typically required to change ownership or register long leasehold rights.
Your SPA should define delay remedies. If it does not, you may have weak leverage—negotiate before signing.
