2. Parts in height:

A. Limit of liability [Article 2-2(b) of the judgment of the court of first instance] Even if a licensed real estate agent is liable for compensating for any damage caused by his/her breach of the duty of care, the transaction party’s obligation to investigate and confirm the transaction relation which the principal of the transaction, who delegated the brokerage, shall entirely belong to the broker and the transaction party’s obligation shall not be deemed to be out

Therefore, in a case where a broker has determined the scope of compensation for the damage incurred to the broker by failing to perform his/her duty to investigate and confirm whether the broker is a real right holder in the course of mediating real estate transactions, if it is recognized that the broker neglected his/her duty to investigate and confirm the transaction relationship and that caused the occurrence and expansion of the damage, it shall be deemed that there was negligence on the part of the client who is the victim, and it shall be deemed reasonable in light of the basic principle of the damage compensation system
