The value of credit money may increase due to some reasons. In the premise of devaluation, there are clear jurisprudential views about the amount of repayment of debt after maturity. However, in case that the value of money increases, how much the debtor should repay? Since the actual due (right) of the creditor and debtor is jurisprudentially an important issue, this question must be clearly answered. Answering to this important question, on one hand, requires a precise examination of some aspects of the issue of credit money, and, on the other hand, needs the presentation of clear jurisprudential proofs. According to the stated assumptions, the research hypothesis is as follows:
The purchasing power of money in the debt is the criterion of payment of debt in the premise of the increased value of the money. Using a descriptive-analytical method and collecting library data, we concluded that in the event of a sharp increase in the value of money, and while the debtor is not able to pay the debt at maturity date, he must pay an amount lower than the nominal amount received to the creditor. However, in the event of a slight increase in the value of the money, the payment of the nominal amount is considered the full payment of the debt. If the purchasing power of money has increased since the time of its receiving until the time of its payment, and the debtor pays the debt after the deadline despite the ability to pay, he needs to pay the received nominal to the creditor to compensate the losses.
