C.

[Ground of recognition] Facts without dispute, Gap evidence 1 through 5, 9, 10 evidence, Eul evidence 6 through 8, and 10 evidence, the purport of the whole pleadings

2. The parties' assertion

A. Since an agreement between the Plaintiff and the Plaintiff is null and void in violation of the mandatory provisions on the payment of fees concluded by the Defendant without registering the establishment of the instant brokerage office without the Plaintiff’s brokerage office’s establishment, the Defendant is obligated to return the commission fee of KRW 220 million received from the Plaintiff as unjust enrichment.

B. The defendant does not engage in a business as a broker for real estate transactions, but only one opportunity to act as a broker, and thus, it cannot be deemed as null and void an arrangement for payment of brokerage fees, and the plaintiff also knew that he is not a licensed real estate agent, and thereby, 2.3 billion won through the sales contract of this case.
