How to check that there are no parents in the account?

If you are not in the same household with your parents, you need to prove kinship. You can only bring the original ID card, original birth certificate, original parent ID card and other materials to the local notary office for notarization of relatives. At this stage, the public security department will no longer issue proof of kinship. For parents who are in the same household registration book with themselves, citizens can directly provide the original household registration book to confirm 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 certificates to the local notary office for notarization of kinship.
