[Ground of recognition] The evidence No. 1-3, Gap evidence No. 2-2, and the purport of the whole pleadings

2. The assertion and judgment

A. The plaintiff asserts that the obligation of this case against the defendant is old, and the obligation of this case was omitted in the creditor list because it was impossible to memory due to joint and several sureties, and thus, the obligation of joint and several sureties should also be deemed exempted. Accordingly, it is reasonable to deem that the defendant was aware of the existence of the obligation of joint and several sureties. Thus, the defendant asserts that the obligation of this case constitutes "the obligation of joint and several sureties which is not recorded in the creditor list in bad faith" under Article 566 subparagraph 7 of the Debtor Rehabilitation

B. (1) Determination is based on the case where an obligor is aware of the existence of an obligation against a bankruptcy creditor before immunity is granted, and thus, the obligor is not required to enter the same in the list of creditors, as stated in Article 566 subparagraph 7 of the Debtor Rehabilitation and Bankruptcy Act.
