Many times, those departments didn't do their work well in advance, and when customers came, they rushed to go through the formalities in order not to let them wait. They will ask the customer to sign first, then organize the documents and write the contents, which are usually related statements such as entrustment or proof.

In fact, this situation can be avoided, as long as they do their work well in advance and print the relevant contents on paper, they can sign immediately when they arrive, without waiting. Therefore, it is not recommended to sign on blank paper by handprint, but rather wait at the scene and see what is on the paper before signing.

I suggest you go back to the notary office afterwards to see what the six blank pieces of paper have written. If you find anything wrong, you should ask for correction or cancellation immediately.
