1. If no written agreement is signed, but the deposit is actually paid, the deposit receipt issued is legally binding and the deposit guarantee is valid. 2. The deposit paid before signing the contract is often the contract deposit. If the payer simply doesn't want to sign the contract again, the deposit can't be refunded. Of course, if the contract cannot be signed objectively due to reasons not attributable to the deposit payer and the deposit receiver (such as the sudden introduction of the purchase restriction policy), the deposit can be refunded.
legal ground
According to Article 586 of the Civil Code, the parties may agree that one party shall pay a deposit to the other party as a guarantee for the creditor's rights. The deposit contract is established when the deposit is actually paid.
