Section 378 then sets the three outcomes: on performance the earnest is returned or credited against the price; if the giver&#8217;s fault prevents performance, the earnest is forfeited; if the receiver&#8217;s fault prevents performance, the receiver must return double.<\/p><\/p>\n\n\n<p class=\"wp-block-paragraph\"><p>The double-return rule is the buyer&#8217;s main lever against a seller who takes a deposit and then sells to someone else at a higher price, or who cannot deliver the title. It is also why sellers prefer to call the sum a &#8220;reservation fee&#8221; and to write their own refund terms. The parties may vary the statutory outcomes by contract, so the written agreement decides; only where it is silent do Sections 377 and 378 apply in full. Where the earnest is excessive in relation to the loss actually suffered, the court may reduce the amount forfeited under the Unfair Contract Terms Act B.E. 2540.<\/p><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"deposits-in-a-thai-property-purchase\">Deposits in a Thai property purchase<\/h2>\n\n\n<p class=\"wp-block-paragraph\"><p><strong>In a resale<\/strong>, the buyer typically pays 5% to 10% of the price on signing the sale agreement, with the balance at the <a href=\"https:\/\/www.thailawonline.com\/th\/glossary\/land-office\/\">\u0e2a\u0e33\u0e19\u0e31\u0e01\u0e07\u0e32\u0e19\u0e17\u0e35\u0e48\u0e14\u0e34\u0e19<\/a> on transfer day. That sum is earnest: the buyer loses it by failing to complete, and can claim double if the seller withdraws. A clause requiring the seller to refund only the single amount on default is common and, being a contractual variation, generally enforceable; a buyer who wants the double remedy must keep Section 378 intact.<\/p><\/p>\n\n\n<p class=\"wp-block-paragraph\"><p><strong>Off-plan<\/strong>, the reservation fee paid on the day of booking is earnest and can be forfeited, but the instalments paid afterwards are part payments of the price and cannot be forfeited as earnest, whatever the developer&#8217;s form says.

A sum paid at the moment of contracting is forfeited under Section 378 of the Civil and Commercial Code when the buyer fails to complete, unless the contract says otherwise.
