2. Determination:

A. 1) In order to establish the office management of claims, first of all, it is required that the office is another person’s business and the intention to transfer the actual benefit of the management to another person, i.e., the intention to transfer the actual benefit of the management on behalf of another person, and furthermore, it is not clear that the process of the office is disadvantageous to the principal or against his/her will (see, e.g., Supreme Court Decision 2009Da71558, Feb. 11, 2010). However, a third party’s repayment is in itself a beneficial benefit to a debtor, and thus, it is not unfavorable to the debtor unless there is any counter-proof, and it is against his/her will. The repayment is deemed a kind of office management. Therefore, the third party who has discharged the obligation is entitled to demand reimbursement against the debtor in accordance with the legal principles of the office management (see, e.g., Supreme Court Decision 4293Da729, Nov. 9, 1961).

B. The summary of the Defendant’s assertion 1 is as follows: (a) the Defendant is almost every process based on the instant construction contract.
