"Assumption of obligation" means a contract under which a debtor has been originally liable to transfer it to a third party in the discharge of liability, or to which the debtor has been responsible for it. In order to assume an overlapping obligation, it is necessary to require the creditor to have the creditor acquire the claim to the person who has directly assumed the obligation to the person who has been liable for it, and to obtain the creditor's consent on the assumption of obligation with respect to the discharge of liability.

At this time, it is overlapping whether the assumption of obligation is exempted.
