 The creditor may apply to the people's court for subrogation in its own name to exercise the debtor's rights against the counterpart, except where such rights exclusively belong to the debtor itself.
 The scope of subrogation shall be limited to the creditor's due claims. The necessary expenses for the obligee to exercise the right of subrogation shall be borne by the obligor. The opposing party may claim against the creditor any defense against the debtor.
