The Definition
A Sale and Purchase Agreement (SPA), known in Thai as Sanya Ja Sue Ja Kai (สัญญาจะซื้อจะขาย), is a legally binding contract between a buyer and seller outlining all terms, conditions, purchase price, payment schedule, and timeline for ownership transfer. It is essential for protecting both parties' rights prior to the official Land Office transfer.
In Thailand, the private SPA supplements the official government form (Tor.Dor.13). While the SPA contains negotiated terms and payment schedules, title transfer strictly occurs upon registration at the Land Department. Governed by the Civil and Commercial Code, Condominium Act, and Land Development Act, standard forms are mandated for developers and condos. Notably, foreigners cannot own land outright but can buy condos (up to 49% foreign quota) using these standard SPAs. Bilingual translation is highly recommended to protect foreign buyers.
Let’s look at a real-world scenario to understand how Real Estate Sale Purchase Agreement is applied during a property transaction.
Title transfers officially at Land Office registration, not upon deposit or final payment. Pre-agreed tax liabilities ensure no closing surprises.
No. Under Thai law, real estate sales must be in writing on an official form and registered at the Land Office to be legally binding.
No. Ownership transfers only when the official Tor.Dor.13 form is signed and registered at the Land Office by a competent official.
The SPA must explicitly state this. Generally, the buyer pays the 2% transfer fee and stamp duty, while the seller pays income or specific business tax.
An SPA is your primary defense against fraud, breach, or unexpected costs. Without a carefully drafted agreement, you have no legal recourse if the seller fails to deliver or misrepresents the property.
Always insist on a bilingual SPA with a lawyer-certified translation. Request a detailed tax estimate worksheet before signing so you know your exact closing costs.
