About the abandonment of inherited property, and does the transfer process require the household registration book of brothers and sisters?

Notarization of the declaration of abandonment of inheritance shall be handled by the parties themselves, and shall not be entrusted to others. If identification of the parties is needed, such as resident identity card and household registration book, etc. You can ask your mother to go to the notary office with the household registration book in person, let them examine the household registration book and the original ID card on the spot, and then bring the above-mentioned documents back by themselves (that is, they have been holding important documents, as the saying goes, it is better to be cautious than to hurt others' hearts).
