A scanned copy of the debt signed by the guarantor to see if the other party recognizes the scanned copy. In essence, the scanned copy belongs to the copy of the evidence, not to the original. According to the rules of evidence in civil procedure, the other party has the right to ask for checking the original evidence. If the original can't be provided and the other party refuses to recognize the scanned copy, the scanned copy can't play the role of proof. If the other party has no objection to the approval of the scanned document, the scanned document is valid.
