Because the cohabitation relationship is dissolved after the cohabitation period, the creditor's rights and debts formed during the cohabitation period due to common production and life should be treated as joint creditor's rights and debts. So during cohabitation, swipe the other party's credit card. If there is no other agreement between them, the credit card has expired and has been separated. Then, first of all, the banking institution will directly ask the cardholder to repay. After repayment, the cardholder may ask the other party to claim repayment.

Legal basis: Article 1054 of the Civil Code of People's Republic of China (PRC).

An invalid or revoked marriage is not legally binding from the beginning, and there are no rights and obligations of husband and wife between the parties. Property acquired during cohabitation shall be handled by the parties through agreement; If the agreement fails, the people's court shall make a judgment according to the principle of taking care of the innocent party. The property disposal of invalid marriage caused by bigamy shall not infringe upon the property rights and interests of the parties to legal marriage. The provisions of this law concerning parents and children shall apply to the children born to the parties concerned.

If the marriage is invalid or revoked, the innocent party has the right to claim damages.
