The first is the "divorce damages" system in the Marriage Law. According to the provisions of the Marriage Law, the following conditions must be met:
Article 46 In case of divorce under any of the following circumstances, the innocent party has the right to claim damages:
(1) Bigamy;
(two) a spouse living with others;
(3) committing domestic violence;
(4) maltreating or abandoning family members.
The second is the return of the bride price. According to the Supreme People's Court's Interpretation on the Application of the Marriage Law of the People's Republic of China (II), the people's court shall support the request of the parties to return the bride price paid according to the custom if it is found that it belongs to the following circumstances:
(1) Both parties have not gone through the marriage registration formalities;
(2) Both parties have gone through the marriage registration formalities, but they have not lived together;
(3) premarital payment, causing difficulties to the payer.
The application of items (2) and (3) of the preceding paragraph is conditional on the divorce of both parties.
As there is no corresponding evidence at present, there may be other possibilities in your situation. Please provide further information for analysis and judgment.
