What you want to ask is, can I ask the bank to write a note on the copy of my ID card when selling a house? Can. According to the query on Hualu.com, when a copy of the ID card is used for house sales, in order to prevent others from using it for other unrelated business, when giving the copy to the other party, in the blank space of the ID copy, it is marked that it is only for this house sale. The business is used once, and it is invalid to handle other unrelated matters. Then sign your name and indicate the date of handling. Therefore, when selling a house, you can ask the bank to write a note on the copy of the ID card.
