I have done this before, and I need the ID card, household registration book, marriage certificate and power of attorney written by the parties concerned (if you can't write it, you can ask the notary of the notary office). The safest way is to call the county notary office in advance to ask about notarization matters and materials to be submitted, so as to avoid a trip in vain. The specific processing time is still relatively fast. When there are not many people, it will be completed in the notary office in 30-60 minutes. The charging standards may vary from place to place. Generally, it is charged by piece, that is, you need to issue several notarized power of attorney to charge. Good luck, hope to adopt!
