A. Defendant B and C are licensed real estate agents.

The defendant Korean Licensed Real Estate Agent Association (hereinafter referred to as the "Defendant Association") is a mutual aid business entity that has entered into a mutual aid agreement with Defendant B with the terms and conditions of compensating for losses to the parties to a transaction where the losses to the transaction occur due to the intention or negligence of a licensed real estate agent on May 6, 2011 through May 5, 201.

The instant building and site were knocked at KRW 113,289,000,000 on October 1, 2013.

The Plaintiff obtained a fixed date on August 23, 201, but was paid KRW 20 million out of the deposit for lease on December 12, 2013, due to the small-sum lessee, the mortgagee of the right to collateral security, and the lessee of the senior fixed date on the date of distribution in the above auction procedure on December 12, 2013.

[Grounds for recognition] The items of evidence Nos. 1 through 5 and the purport of the whole pleadings

2. The parties' assertion

A. Defendant B and C did not verify and explain the lease status while jointly mediating the instant lease agreement.

The Plaintiff, who is a professional qualification, entered into a lease agreement after hearing only the explanation of the said Defendants.

Although the auction was commenced on the multi-family house in this case, the plaintiff failed to recover KRW 30 million out of the lease deposit due to senior lessee.

Therefore, it is true.
