1. The purpose of your loan itself is to pay off debts, so it is not a refinancing. I don't know what the purpose of the loan you wrote at that time was, so I assumed it was this.

If you can't repay the loan, and the money belongs to personal debt (notarization), they can only hold you accountable. If this personal debt is not notarized, the credit company can apply for freezing your wife's property and sue you for repayment, and may deduct your wife's account to repay the debt.

You don't usually go to jail in this situation, depending on how the other party handles it.
