1. Determination on the cause of the claim

A. On April 14, 2005, the plaintiff Eul borrowed KRW 5,00,00 from the plaintiff on August 14, 2005 with interest rate of KRW 20% per annum. The defendant Eul jointly guaranteed the above loan obligation of the defendant Eul. The defendants paid approximately KRW 800,000 out of the above loan obligation to the plaintiff and did not repay the principal and the remainder damages. Thus, the defendants jointly and severally agreed to the plaintiff with interest rate of KRW 5,00,000 and KRW 800,000,000 from the above 80,000,000,000 won per annum from the above 10,000 won per annum from the above loan obligation to the 200,000 won per annum from the 100,000,000 won per annum from the above loan obligation to the 200,000,000 won per annum from the 200,000,000 won per annum.

B. 1) The Defendants asserted that as to the authenticity of Gap evidence No. 1 (a) was not recognized since Gap evidence No. 1 (a) received a blank paper from the Plaintiff, the Defendants’ personal information was written, and the defendants’ personal information was affixed to the defendant B’s seal imprint and the defendant C’s seal imprint, and then delivered it to the Plaintiff again. The Plaintiff’s personal information, principal, loan, date of borrowing, payment date, and interest were arbitrarily stated in the above loan certificate before the Plaintiff filed the instant lawsuit. Thus, the defendants asserted that the authenticity of Gap evidence No. 1 is not acknowledged.

B. A private document shall be authentic when it bears the signature, seal or seal of the principal or of his agent.
