2. The plaintiff's claim is dismissed.

3. All costs of the lawsuit shall be borne by the Plaintiff.

A. The Plaintiff is a person who runs the printing business with the trade name “C” and the Defendant is a person who runs the advertising business with the trade name “D,” and the Plaintiff’s price, such as printed matters supplied to the Defendant, is KRW 27,037,400.

On December 31, 2012, the Plaintiff and the Defendant agreed to pay KRW 20 million to the Plaintiff by June 30, 2013, deducting KRW 70,37,400 from the above money.

Therefore, the defendant is obligated to pay to the plaintiff the above 20 million won and delay damages.

B. The plaintiff's claim of this case is without merit due to the following reasons.

① There is no transaction between the Plaintiff and the Defendant, and the claim price in this case occurred in the transaction with the Plaintiff and the F in which they jointly operated.

However, the Plaintiff prepared the instant confirmation document with the fact that the Plaintiff was transferred the claim from F, and the Plaintiff did not actually receive the transfer of the claim from F.

② The instant confirmation document (Evidence A1) is merely a false document prepared by the Plaintiff to avoid additional collection in a tax investigation, even though there was no actual transaction, as if there was a transaction with the Defendant.

2. As long as the authenticity of the judgment document is recognized, the court shall recognize the existence and content of the declaration of intent in accordance with the content of the document unless there is any counter-proof, and shall not reject it without any reasonable explanation, but even if it is a disposition document attested to be genuine, the court may reject its probative value when there exists any counter-proof or there is a reasonable ground to see the content of the document as contrary to objective truth.

(see, e.g., Supreme Court Decision 93Da57117, Feb. 8, 1994). First, we examine whether the Defendant’s obligation against the Plaintiff, as stated in the instant confirmation document, is existing.

The representative B of the advertising company D is in favor of the mutual interest in the quality of printed materials with C.
