I borrowed money from a friend and gave them a blank check and promissory note. I paid them back in installments but they haven’t returned the documents. Now they’re trying to deposit the check in the bank and file a case. I stopped the check. What should I do now?

You should immediately contact your friend and request the return of the check and promissory note, as you have paid the debt. If they refuse, you can file a case in court to seek their return. You can also argue that stopping payment on the check is justified as it was given under duress and you have already repaid the loan.
