The Definition
In Thailand, the sales contract, known as the Sale and Purchase Agreement (SPA or Sanya Ja Sue Ja Kai), is the primary binding document outlining property details, price, payment schedules, responsibilities for taxes and fees, warranties, and transfer date, signed by both buyer and seller with each page initialed. It must align with Land Department records and often precedes the official Tor.Dor.13 form signed at the Land Office for title transfer registration.
Governed by the Civil and Commercial Code, Condominium Act, and Land Development Act, the SPA must often follow mandatory standard forms to protect buyers. Unlike Western markets where a single comprehensive SPA is standard, Thai SPAs are typically basic and separate from the official Tor.Dor.13 Land Office form, which alone effects legal title transfer. Foreigners face extra scrutiny on ownership eligibility and must ensure SPAs specify compliant structures (like leaseholds or condo quotas) and attach Foreign Exchange Transaction (FET) forms for fund repatriation. The Department of Lands oversees registration, while AMLO may scrutinize large foreign transactions.
Let’s look at a real-world scenario to understand how Real Estate Sales contract is applied during a property transaction.
The private SPA laid out the terms and protected both parties during the payment period, while the Tor.Dor.13 registration officially transferred the title.
No, it must lead to Tor.Dor.13 signing and registration at the Land Office; otherwise, it is invalid for title transfer.
Non-beneficial clauses to buyers are unenforceable under the Condominium Act, but a lawyer review is highly recommended to avoid gaps.
Yes for condos or leaseholds, but it must explicitly exclude direct land ownership and include the FET form for proof of funds.
Mishandling the sales contract risks invalid transfers, deposit forfeiture, or tax disputes, potentially costing millions in a market where only registered documents confer ownership. Mastering it ensures smooth title handover and legal protection in Thailand's foreigner-restricted landscape.
Always demand SPA alignment with Land Office records pre-signature and engage a bilingual lawyer for review. Attach the title deed, permits, and FET Form copies to avoid 30+ day transfer delays.
