If my parents and I are in the same household registration book, we can register directly if we want to remarry. The ex-husband's name shows that he is not a relative in the household registration book, which means that he has moved away. It doesn't really matter. Citizens can directly provide the original residence booklet to prove kinship; For parents who are not in the same household registration book, the household registration department has the right not to issue a household registration certificate because they cannot find out their kinship. Therefore, citizens can only bring their parents' ID cards, household registration books, ID cards and birth certificates to the local notary office for notarization of kinship.

The household registration book shows divorce, and you can get a marriage certificate. Although I am in the same household registration book as my ex-husband, but now I am married to someone else, I can move my household registration to my current husband's household registration. If you remarry, as long as you don't register with the registered police, it won't be displayed in the original household registration book.
