Reservation Agreement in Thailand: 7 Key Clauses That Protect Your Investment
You sign a document in Thai, transfer 100,000 THB to a developer's account, and only on the flight home do you wonder what you actually agreed to. This is not a hypothetical scenario, it is a recurring pattern among international investors who skip a proper review of the reservation agreement.
The reservation agreement (in Thai: สัญญาจอง) is the first legally binding document in a Thai property purchase. Unlike real estate contracts in many Western jurisdictions, it is not notarised, not registered in any land registry, and not subject to statutory consumer protection laws equivalent to those in the EU. Every protection you have as a buyer depends entirely on the clauses written into that document.
Whether you are acquiring a freehold condominium unit within the 49% foreign quota, or securing a 30-year leasehold on a villa, the reservation agreement serves as your negotiating anchor. Without it, a developer can sell the same unit to another buyer the same day.
Quick answer
- Reservation deposits typically range from 50,000 to 200,000 THB (approx. 1,300 to 5,200 USD) and are paid directly to the developer's corporate account
- A reservation agreement is NOT equivalent to a notarised purchase contract, it provides no court-backed protection comparable to a land registry entry
- The standard validity period is 14 to 30 days, after which the buyer must sign a Sale and Purchase Agreement (SPA) or forfeit the deposit
- The refund clause is negotiable, but most developers default to a non-refundable deposit structure
- A licensed Thai lawyer (Thai Bar Association member) will review the agreement for 15,000 to 40,000 THB (approx. 400 to 1,100 USD)
- Remote purchases require a Power of Attorney authenticated by a notary and apostilled in the buyer's country of residence
Options and scenarios
Scenario 1: Freehold condominium within the 49% foreign quota
Under the Condominium Act B.E. 2522 (and its amendments), foreign nationals may hold full freehold title to condominium units provided that the aggregate foreign ownership in any single building does not exceed 49% of total sellable floor area. The reservation agreement for this structure must explicitly state the unit number, floor, area in square metres, and a written confirmation from the developer that the unit falls within the available foreign quota.
A critical requirement: funds for a freehold purchase must be remitted to Thailand in a foreign currency via international wire transfer and converted to Thai Baht by a licensed Thai bank. That bank will issue a Foreign Exchange Transaction Form (TT3 / Thor Thor 3). Without a valid TT3, the Land Department will not transfer title. The reservation agreement should include a conditional clause making the transaction contingent on obtaining this document.
Scenario 2: 30-year leasehold on a house or villa
Foreign nationals cannot own land in Thailand. The most common alternative is a registered leasehold (leasehold) recorded at the Land Office for a period of up to 30 years, typically with a contractual renewal option. A reservation agreement in this structure covers the right to enter into the lease, not ownership of the land itself.
The reservation document should commit the seller to registering the lease against the strongest available land title, ideally a Chanote (Nor Sor 4 Jor), which contains GPS-surveyed boundaries and represents the Thai equivalent of a full title deed. Weaker titles (Nor Sor 3, Nor Sor 3 Gor) offer significantly reduced legal protection.
Important note: the option to renew a Thai leasehold for an additional 30 years is not judicially enforceable under current Thai law. It remains a contractual obligation between the parties only, not a guaranteed statutory right. This has real implications for asset valuation.
Scenario 3: Thai company (Thai Company Limited)
Some investors incorporate a Thai limited company in which the foreign shareholder holds 49% and Thai nationals hold 51%. The company, as a Thai legal entity, can acquire freehold land. This structure is legal when the company conducts genuine business activity. Nominee arrangements, where Thai shareholders hold shares in name only, with no real capital contribution or decision-making power, are illegal under the Land Code and the Foreign Business Act and can result in criminal penalties.
A reservation agreement signed in a company's name must state the full registered company name and company registration number.
Scenario 4: Remote purchase via Power of Attorney
International investors who cannot be present in Thailand can authorise a local lawyer to act on their behalf through a Power of Attorney (PoA). The document must be prepared in both English and Thai, signed before a notary public in the buyer's home country, and authenticated with an Apostille issued by the relevant authority. Processing time is typically 7 to 14 business days. Additional legal costs for PoA preparation range from 10,000 to 20,000 THB on top of standard legal fees.

Risks and mistakes
1. Signing a Thai-only agreement. Thai courts treat the Thai-language version as legally binding in the event of a dispute. Always request a bilingual version (English and Thai) and have your lawyer verify that both texts are substantively identical.
2. No refund clause in the deposit terms. Standard developer templates almost universally include a non-refundable deposit provision. Negotiate a conditional clause: if legal due diligence reveals title defects or confirms the foreign quota is exhausted, the deposit should be returned in full.
3. Unverified foreign quota status. A developer's verbal assurance that the 49% quota is available carries no legal weight. The Land Department verifies quota status only at the point of registration. If the quota is already exhausted, you lose both time and your deposit. Require written confirmation in the reservation agreement itself.
4. Skipping the Chanote check. A Chanote is the highest-grade land title in Thailand. Before signing any agreement, a lawyer should verify at the Land Office that the land carries no mortgage, lien, or encumbrance. This search typically costs a few thousand THB and is non-negotiable due diligence.
5. Underestimating the reservation deadline. International wire transfers (SWIFT) can take 3 to 5 business days from a foreign bank to a Thai receiving account. If your reservation window is 14 days and you are sending funds from abroad, that timeline is tighter than it appears. Negotiate a longer reservation period upfront.
6. Transferring funds to a personal account. Deposit payments should be made to the developer's corporate bank account. Payments to the personal account of a company owner complicate any future legal claim and are a significant due diligence red flag.
7. Ignoring home-country tax obligations. As a tax resident of your home jurisdiction, you are likely required to report foreign rental income and capital gains. Tax treaty provisions between your country of residence and Thailand may affect how income is taxed, but they do not eliminate the reporting obligation. Consult a cross-border tax adviser before completing the purchase.
FAQ
Is a Thai reservation agreement equivalent to a notarised purchase contract?
No. A reservation agreement in Thailand is an ordinary civil contract that requires no notarisation and is not registered in any land registry. Its protective value depends entirely on the specific clauses it contains. It offers significantly less statutory protection than purchase contracts in most EU jurisdictions.
How large is a typical reservation deposit for a condo in Thailand?
Generally between 50,000 and 200,000 THB (approximately 1,300 to 5,200 USD). For premium or luxury properties, deposits can reach 500,000 THB or more. The deposit is credited toward the final purchase price.
Can I get my reservation deposit back if I change my mind?
Under most standard developer agreements, no, the default is non-refundable. However, a conditional refund clause is negotiable, particularly one tied to unsatisfactory results from a legal due diligence review. This is one of the most important points to negotiate before signing.
What is a Chanote and why does it matter?
A Chanote (Nor Sor 4 Jor) is the strongest form of land title in Thailand. It contains GPS-verified plot boundaries and is registered at the Land Office with full survey documentation. It is the closest Thai equivalent to a registered freehold title deed. Weaker titles such as Nor Sor 3 and Nor Sor 3 Gor provide considerably less legal security and can complicate future sales or financing.
Do I need a Thai lawyer to review a reservation agreement?
Yes. Legal review costs between 15,000 and 40,000 THB. A licensed lawyer will verify consistency between the English and Thai texts, assess the refund and cancellation terms, confirm the unit description is accurate, and check the status of the foreign ownership quota.
How does a remote purchase via Power of Attorney work?
The process follows this sequence: you select the property (in person or via a virtual viewing), sign the reservation agreement, issue a Power of Attorney notarised and apostilled in your home country, your lawyer conducts due diligence, you sign the Sale and Purchase Agreement, you transfer funds via SWIFT international wire, the Thai receiving bank issues the TT3 form, and your lawyer registers the title at the Land Department.
How does buying property in Thailand compare to buying in Cambodia?
In Cambodia, foreign nationals may hold freehold title to residential units from the first floor and above under the 2010 Law on Foreign Ownership. A 'hard title' (equivalent to the Thai Chanote) is required. Thailand limits foreign freehold ownership of condominiums to 49% of a building's total floor area. Cambodia does not require a foreign exchange transaction form equivalent to Thailand's TT3.
What is the TT3 form and why is it required?
The TT3 (Foreign Exchange Transaction Form, also called Thor Thor 3) is issued by a Thai bank when foreign currency is converted to Thai Baht. For a foreign national purchasing a freehold condominium unit, this document is mandatory evidence that the funds originated abroad. The Land Department will not process the title transfer without it.
Is a Thai company a safe ownership structure for foreign investors?
A company conducting genuine business activity is a legal structure. Nominee arrangements, where Thai shareholders hold shares in name only with no real involvement, violate the Land Code and the Foreign Business Act. The Department of Business Development (DBD) and Land Department conduct periodic checks on such structures. Legal and compliance risk is significant if the structure is not properly established.
How long does the full process take from reservation to title transfer?
For a secondary-market freehold condominium: typically 30 to 90 days. For off-plan purchases, the timeline depends on the construction schedule. Leasehold structures and company purchases generally take 60 to 120 days from reservation to completed registration.
