Legal analysis: engagement is not a necessary procedure stipulated by law, but it is not restricted by law. There is no legal provision for the engagement deposit, which should be regarded as a voluntary gift on the condition of marriage. If you regret your engagement, as long as you don't actually get married, you can ask for a refund in principle, and both parties can negotiate to refund all or part of the deposit. Engagement is a kind of contractual behavior in law, and it is also an identity contract. This identity contract has several characteristics: 1, the conclusion of the marriage contract shall not be represented, otherwise it will have no legal effect; In other words, the engagement can only be established if both men and women agree. 2. Only those who have the legal capacity for engagement can engage in engagement. The legal definition of engagement ability is based on age: male 17 years old, female 15 years old. A marriage contract concluded in violation of this provision is not invalid, but the parties or legal representatives may request the court to cancel it. Because, for minors under the age of 20, their engagement must be approved by the legal representative. 3. The engagement should not be enforced. Although the engagement should be observed, it should also follow the wishes of both men and women. If one party fails to perform, it cannot be enforced.
