When monographic work on debtor’s default is considered, both the importance and the depth of the subject is clearly understood. The subject also includes multi-directional problems and discussions on agreements binding two-way debt, in addition to contradictions to a simple debt. This is because once the debtor’s default has taken place, the only obstacle for the creditor is not only the status and conditions of the debtor, but also the properties of the specific performance of the relevant execution. Even though the specific performance claim is an expression of the creditor’s right on the contract rather than a sanction about the default, the properties of the contracts that bind two-way debt should be considered seperately depending on the creditor’s execution for specific performance that make up the essential claim.Accordingly, the specific performance’s compliance is based on the settled execution before the contradiction to debt has taken place, in other words, the debtor’s lapse into default. In cases where the execution is fulfilled by substitute performances, partial performance, the act of execution or the settlement of the execution result, or whether the result is positive or negative execution, unique results will inevitably arise for specific performance
