Reservation Agreement in Thailand: 7 Key Clauses That Protect Your Investment

Varsovia EstatePublished on August 16, 20269 min read

Foreign buyers accounted for a record 28% of premium segment transactions in Bangkok in recent years, with thousands of condominium units transferring to international purchasers annually. For any overseas investor, the reservation agreement is the first document signed after selecting a property - and this deceptively simple form is the source of some of the most expensive mistakes made in Thai real estate.

The Reservation Agreement (in Thai: สัญญาจอง) functions similarly to a pre-purchase commitment in other jurisdictions, but with one critical distinction: Thai law does not regulate its form or minimum content. Everything depends on negotiation. This means the foreign buyer must independently ensure that protective clauses are included, because developers will not add them by default.

Quick answer

  • Reservation deposit typically ranges from 50,000 to 200,000 THB (approximately 1,400 to 5,600 USD), representing 1-3% of the unit price
  • Reservation validity is usually 14-30 days, during which the buyer must sign the Sale and Purchase Agreement (SPA)
  • Deposit refunds are not guaranteed by law - the right to a refund must be explicitly written into the reservation agreement
  • Foreign nationals may purchase a condominium on freehold title only within the 49% foreign quota allocated per building
  • An independent lawyer (not affiliated with the developer) should review all documents before any payment - legal opinion fees typically range from 5,000 to 15,000 THB
  • A notarised Power of Attorney issued in your home country and apostilled allows the entire transaction to be completed remotely

Options and scenarios

Scenario 1: Freehold condominium purchase from a developer (off-plan or ready)

This is the most common route for international investors in Thailand. The developer provides a standard reservation form, and the buyer pays the deposit by international wire transfer. Critically, funds must arrive in Thailand from abroad in foreign currency. The receiving Thai bank issues a Foreign Exchange Transaction Form (FETF), also known as Thor Tor 3, which confirms that foreign currency was remitted into Thailand for property purchase purposes. Without this document, the Land Office will refuse to register title transfer.

The reservation agreement should include: a precise description of the unit with the chanote number (the Thai equivalent of a title deed), the price in THB, the payment schedule, a clause confirming the availability of foreign quota, a refund condition if quota is unavailable, and the deadline for signing the SPA.

Scenario 2: Leasehold villa or house (30-year term)

Foreign nationals cannot own land in Thailand. Villas and houses are therefore acquired through a 30-year registered leasehold, often with an option for two further renewals - totalling up to 90 years in practice, although renewals are not guaranteed under statute. The reservation agreement should include a binding commitment from the developer to register the lease at the Land Office (only a registered leasehold is enforceable against third parties), along with precise terms for renewal conditions.

Scenario 3: Cambodia freehold condominium (regional comparison)

Under Cambodia's Law on Foreign Ownership of Properties in Co-Owned Buildings (2010), foreign nationals may purchase units on freehold title from the first floor upward. The title instrument is a 'hard title' - a centrally registered ownership document. Reservation agreements in Phnom Penh follow a similar structure to Bangkok, but deposits tend to be lower (from approximately 1,000 USD). Buyers should verify whether the developer holds a hard title on the land rather than a 'soft title' (a locally recognised but legally weaker document).

Risks and mistakes

1. No refund clause in the agreement. In many jurisdictions, developers are legally required to return deposits under defined circumstances. In Thailand, there is no such statutory obligation. If the reservation agreement is silent on refunds, the deposit is forfeited - even if the developer subsequently changes the unit specification or delivery timeline.

2. Sending payment in local currency without proper international routing. The Land Office requires a Thor Tor 3 document confirming that foreign currency entered Thailand from abroad. A transfer converted by an intermediary bank before arriving in Thailand may not satisfy this requirement. The safest approach is to wire funds directly in USD or THB from an international currency account to the developer's Thai bank account, with a clear reference indicating the purpose of the transfer.

3. Signing without verifying the chanote. The chanote (Nor Sor 4 Jor) is the highest-grade Thai title deed - it confirms ownership, land boundaries, area, and encumbrances. A lawyer should verify the chanote at the Land Office before the deposit is paid, not after. This step can reveal mortgages, disputes, or discrepancies in floor area that would fundamentally affect the investment.

4. Ignoring the 49% foreign quota. If a building's foreign quota is already fully allocated, a foreign buyer cannot register ownership - even after paying the full purchase price. A reputable developer will provide up-to-date data on the ownership structure. Always request a written confirmation of available foreign quota before signing.

5. Power of Attorney without apostille. Investors completing transactions remotely grant authority via a notarised Power of Attorney. This document must carry an apostille issued by the competent authority in the investor's home country, and must be translated into English or Thai by a certified translator. Without apostille certification, the Thai Land Office will not process the registration.

6. No arbitration clause. In the event of a dispute with a developer, a foreign investor may face litigation in a Thai court - conducted in Thai, costly, and time-consuming. A well-drafted reservation agreement should include a dispute resolution clause specifying arbitration (for example, through the Thai Arbitration Institute) with English as the language of proceedings.

7. Skipping independent legal review. Developers' standard forms are drafted in their favour. An independent lawyer with experience in foreign property transactions will identify missing protective clauses, ambiguous delivery terms, and unenforceable penalty provisions before they become costly problems.

FAQ

Is a reservation agreement in Thailand legally binding?

Yes. A reservation agreement in Thailand is a binding civil contract under the Thai Civil and Commercial Code. However, its content is not regulated by statute - all terms depend entirely on what the parties agree. This makes independent legal review before signing essential.

How much is the reservation deposit for a condominium in Thailand?

Typically between 50,000 and 200,000 THB, representing approximately 1-3% of the unit price. For luxury units in Bangkok or Phuket, the deposit can reach 500,000 THB.

Can I get my reservation deposit back if I change my mind?

Only if the reservation agreement explicitly provides for this. Standard developer forms typically treat the deposit as non-refundable. It is worth negotiating a conditional refund clause - for example, in the event of a failed due diligence or unavailability of the 49% foreign quota.

What is the difference between a reservation agreement and an SPA in Thailand?

The reservation agreement secures the unit and sets the deadline for signing the full contract. The Sale and Purchase Agreement (SPA) contains the complete payment schedule, penalty provisions, finish specifications, and handover date. The reservation agreement is a preliminary commitment; the SPA is the binding purchase contract.

How does a remote purchase from abroad work?

The investor grants a notarised Power of Attorney in their home country, obtains an apostille, has the document translated by a certified translator, and sends the original to a trusted lawyer or representative in Thailand. The appointed attorney signs contracts and represents the buyer at the Land Office. Funds are transferred directly from the investor's international bank account.

Does a foreign consulate in Bangkok help with property transactions?

A consulate may certify a signature on a Power of Attorney, but it does not provide legal advice or review contracts. Consular certification is not equivalent to an apostille - they are two distinct procedures serving different legal purposes.

What taxes apply when buying a condominium in Thailand?

On a new-build purchase, the buyer typically pays a Transfer Fee of 2% of the Land Office's assessed value, though developers frequently split this cost equally with the buyer. Rental income tax and potential capital gains tax on resale are separate matters that international investors must report in accordance with their home country's tax rules and any applicable double taxation treaty.

Is a chanote the same as a title deed in other countries?

Functionally yes. A chanote (Nor Sor 4 Jor) confirms ownership rights, land boundaries, area, and encumbrances. The key distinction is that a chanote is a physical document held at the Land Office, not a centralised electronic register as found in some European jurisdictions.

How long does the full purchase process take, from reservation to title registration?

For a secondary market (ready) property, the process from reservation agreement to Land Office registration typically takes 30-60 days. For off-plan developments, the reservation is signed at the outset, but title registration occurs only upon building completion - which may be 12-36 months later.

Do I need a Thai bank account to buy a condominium in Thailand?

It is not a formal legal requirement. Funds can be transferred directly to the developer's or lawyer's account. However, a Thai bank account simplifies ongoing property management - paying common area fees, utilities, and local taxes once you own the unit.
