A. As to the identity of the guarantor column of the certificate No. 1 (statement of performance of obligation), the plaintiff consistently asserted that the defendant has forged the above certificate of performance of obligation from the first instance to the first instance trial, and that the plaintiff does not expressly dispute the identity of the plaintiff's seal. ② The plaintiff delivered the certificate No. 2 (a sales contract) to the defendant, who is his spouse, a copy of the plaintiff's seal and forged the letter of performance of obligation. This assertion can be viewed to the purport that the plaintiff's seal of the guarantor column of the certificate of performance of obligation is identical in appearance to that of the plaintiff's seal. ③ The plaintiff's seal of the guarantor column of the certificate of performance of obligation is identical to the plaintiff's ordinary seal of the plaintiff's letter of performance of obligation, ④ The court of first instance confirmed that the above certificate of performance of obligation is identical to the plaintiff's ordinary seal of the plaintiff's letter of performance of obligation, and the plaintiff's appeal against the plaintiff is accepted after the second day of the above statement of performance of obligation.

B. The plaintiff.
