Signed loan documents for a HELOC have disappeared between signing at the branch and inter-office mail to the Note department. The branch has photocopies of the signed loan documents. If the originals do not show up, do we ask the borrower to sign a new set of documents? If so, do we have to start the rescission clock over again when they re-sign? Or can we use the same date that the original docs were signed since we have copies and proof that they were in fact signed and just misplaced?
