Whether flash marriage and divorce can claim the return of betrothal gifts can be determined first:
 1. After the betrothal gifts are paid, the two parties have gone through the marriage registration procedures but have not lived together, such as those who started living apart after marriage, and then both parties divorced again.
 However, here we need to be clear about what constitutes a common life:
 (1) Both parties have a common residence, such as renting a house or buying a house together;
 (2) There is normal sexual life between husband and wife;
 (3) The husband and wife have a common spiritual life, which mainly refers to mutual understanding and consolation based on the spouse's identity;
 (4) The husband and wife have fulfilled the obligation of mutual assistance;
 (5) The husband and wife have fulfilled their other family obligations.
 2. After the payment of the betrothal gifts, the two parties married and went through the marriage registration, but this led to difficulties in the life of the betrothal gifts giver, and the two parties lived together for a relatively short period of time, which generally means no more than one year, and then the two parties quickly divorced.
 Therefore, if you want to return the betrothal gifts in the case of flash marriage and divorce, one is to see whether the two parties have a common life, and the other is to see whether it causes difficulties for the other party, so this is not absolute.
