From November 209 to January 20, 2010, the construction period for the construction of electricity, facilities, and interior and exterior finishing construction among the new construction of a multi-household (hereinafter referred to as “instant sub-household”) was determined as KRW 457,200,000 of the construction amount (excluding value-added tax) and entered into a subcontract.

B. B and other subcontractors completed the instant construction of the instant loan, but did not receive the construction cost properly.

Accordingly, the owner F completed the registration of ownership transfer by payment in kind to the subcontractor, such as B, etc., and the subcontractor, such as B, etc., decided to obtain a loan from a financial institution as security at the same time as the registration of ownership transfer.
