1. Paying the deposit can change the wedding scene, but paying the deposit will form a service contract relationship with the wedding company (there is no written contract, which is actually such a relationship). Whether or not to return the deposit depends on the contract concluded at the time of delivery, because the so-called deposit is a part of the total amount paid in advance by Party B in order to determine some behaviors of Party A, unless it was agreed to return the deposit in some cases at that time. Moreover, the current situation needs to conform to the conclusion of the contract, otherwise, not only the deposit cannot be returned, but even a new deposit needs to be paid (if the contract is unilaterally broken, the breached party has the right to demand double deposit payment or return).
2. If the contract is terminated because of personal reasons to change the wedding site, the deposit will definitely not be returned. According to the provisions of the Guarantee Law, when the deposit is used as the form of guarantee, if the party paying the deposit fails to perform the contract, the party receiving the deposit may confiscate the deposit. If the party accepting the deposit breaches the contract, it shall double the deposit. According to Article 1 16 of China's Contract Law: "If the parties agree on both liquidated damages and deposit, when one party breaches the contract, the other party may choose to apply the liquidated damages or deposit clause."
3. It can be seen that when one party breaches the contract, the deposit penalty and liquidated damages cannot be applied at the same time. If the wedding company does not violate the agreed liquidated damages, the deposit is non-refundable.
