According to the provisions of Article 12 of the Marriage Law of the People's Republic of China, invalid or canceled marriages are invalid from the beginning. The parties concerned do not have the rights and obligations of husband and wife. The property acquired during the period of cohabitation shall be disposed of by the parties through agreement; If no agreement is reached, the people's court shall make a judgment in accordance with the principle of caring for 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 a lawful marriage. The provisions of this Law concerning parents and children shall apply to the children born to the parties concerned.
 The term "void from the beginning" in this article refers to the fact that an invalid or revocable marriage is not protected by law from the beginning only when it is declared void or revoked according to law. For a marriage that has been declared invalid or revoked, the property obtained by the parties during their cohabitation shall be treated as joint ownership. Except where there is evidence proving that it is owned by one of the parties.
