The Definition
In Thailand's property market, earnest money (known as "arrathon" or deposit given at contract signing) is a sum paid by the buyer to the seller simultaneously with entering a sales agreement, serving as proof of contract formation and security for performance under Section 377 of the Civil and Commercial Code (CCC). It demonstrates the buyer's good faith and seriousness, typically ranging from 5-10% of the property price in real estate deals. If the buyer fulfills the contract, the earnest is refunded or deducted from the final payment; if they breach, the seller may forfeit it as damages.
Western buyers often expect earnest money to be held in a neutral third-party escrow with refund contingencies like inspection or financing failures, as in the US. In Thailand, it is directly given to the seller at contract signing without mandatory escrow, increasing risk if disputes arise, and lacks standardized contingencies unless explicitly negotiated. Forfeiture upon buyer default is stricter here, with no automatic refunds for minor issues, contrasting flexible Western protections.
Without clear contract clauses, buyers risk total forfeiture of the deposit if they back out for any reason, as Thai law presumes it as damages under CCC Section 377, unlike conditional Western escrows. Sellers may demand high amounts (10%+) upfront without holding funds securely, exposing buyers to fraud if the seller vanishes or encumbers the property. Disputes over refunds lead to costly Civil Court battles, especially if earnest is verbal or post-signed, invalidating protections per Supreme Court rulings.
Earnest money rules apply identically to foreigners and Thai citizens under CCC Section 377, as it's a general contractual mechanism not differentiated by nationality. Foreigners face broader property ownership restrictions (e.g., no land ownership, limited condos under Foreign Business Act), but earnest handling in reservations or leaseholds remains the same. Both must negotiate protections in contracts, though foreigners often use agents to mitigate risks in title transfers at the Land Department.
Governed by Section 377 of the Civil and Commercial Code (CCC), which deems earnest as proof of contract conclusion and allows forfeiture if the payer breaches, unless adjusted by agreement. The Department of Lands oversees property transfers linked to such contracts, while disputes may involve Civil Courts referencing Supreme Court Judgment No. 513/2538 (1995), confirming earnest must be given at signing, not later. No specific statutes mandate it, but it's accessory to written principal contracts like sales agreements.
Let’s look at a real-world scenario to understand how Earnest Money is applied during a property transaction.
If buyer completes: earnest refunds/adjusts, total paid 5M THB. If seller breaches: they must return double (1 million THB) per negotiated clause or CCC rules.
The Situation: A Thai buyer signed a villa sales contract in Phuket, paying 1 million THB earnest (8% of 12.5M THB price).
The Challenge: Buyer later withdrew due to personal financing issues without contingencies, losing the full deposit as seller forfeited under CCC Section 377, sparking a court dispute costing extra 200K THB in fees.
The REMAX Difference:
A REMAX agent insists on written contingencies (e.g., financing clause) and escrow-like lawyer holding, plus double-return on seller breach, preventing forfeiture and saving the buyer 1M+ THB.

Mishandling earnest money can cost buyers 10%+ of property value instantly via forfeiture, derailing investments in Thailand's non-escrow system. Sellers gain leverage but risk disputes; mastering it ensures smooth transfers and protects against defaults.
Always negotiate a "double earnest" clause (seller returns 2x on their breach) and use a trusted lawyer's account for holding—never hand cash directly to avoid fraud in off-plan or resale deals.
Reality: Refunds require explicit contract contingencies; otherwise, CCC Section 377 allows full forfeiture on buyer breach, regardless of reason.
Reality: It must be cash/property given at signing to qualify as earnest; post-contract or guarantees are not earnest and lack CCC protections.
