定金

• 拼音: dìng jīn
• 汉字拆解: 定 = 宀 + 正 (to settle, fix); 金 = pictograph of metal nuggets under the ground (gold, money)

含义

Deposit; earnest money. A legally binding advance payment made to secure a transaction, subject to forfeiture or double-return rules upon breach.

Legally distinct from 订金 (a simple advance that can be returned). Under Chinese contract law, if the payer defaults the 定金 is forfeited; if the payee defaults they must return double. Commonly used in property purchases, vehicle sales, and high-value contracts.

例句

2. 由于卖方单方面违约，买方依法要求对方双倍返还定金。

正确说法

• 根据合同约定，任何一方违约均须承担定金罚则的法律后果。(According to the contract, either party in breach must bear the legal consequences of the deposit penalty clause.)
• 购车时支付定金后，销售方有义务按约定时间交付车辆，否则须双倍返还。(After paying the deposit for a vehicle purchase, the seller is obligated to deliver the car at the agreed time; otherwise, double the amount must be returned.)

错误说法

• 定金和订金是一样的 — they are legally distinct; 定金 carries statutory penalty rules whereas 订金 is just an advance payment with no mandatory penalty structure
