Loan packages arrive with a duplicate set marked for the borrower, and that set is what stays behind at the end of the appointment. It exists because borrowers need a record of what they signed — for their files, for their accountant, and in particular so they can act on the rescission period where one applies, which requires them to have the notice and the terms in hand. The originals go back to the lender, since those are the instruments that will be recorded and relied upon. Each alternative fails a different way. Retaining originals of anything would break the package. Sending the borrower away with nothing removes their ability to review or rescind. And letting the borrower choose which documents to retain leaves the package incomplete and the borrower's set arbitrary. Where a right of rescission applies, the agent should confirm the borrower has the required copies of the notice, which is a common and consequential omission.
