1. The Plaintiff filed an additional application for modification of the part of the claim for the confirmation of existence of each obligation based on the purport of the claim and the written request for modification as of February 21, 2017, April 3, 2017, and May 16, 2017, with the purport that the Plaintiff filed an additional application for modification of the claim for the confirmation of existence of obligation with respect to each of the materials supply apartment and installation contracts listed in the separate sheet No. 1 as of February 21, 2017 and April 3, 2017, and the Defendant filed an additional application for modification of the claim for the confirmation of existence of obligation with respect to each of the insurance contracts listed in the separate sheet No. 2 as of May 16, 2017 (hereinafter referred to as “each of the claims in this case”).
