However, the sale of this case is null and void because it is considerably difficult to register the site ownership registration of the apartment at the time of the sale of this case, and the registration is not made due to the failure to exercise the city.

In addition, it was not possible to lend bank interest loans due to the above circumstances. Since the plaintiffs intended to obtain a loan as security and pay the purchase price, the important part of the sales contract, or the plaintiffs were not aware of it.

Defendant C and D explained the particulars on the register of ownership of the site at the time of the instant sales contract, and explained them to the Plaintiffs as such.

The Plaintiffs, due to the foregoing circumstances, have renounced the down payment paid to E and incurred considerable damages for the down payment by rescinding the instant sales contract.

This is caused by the violation of the obligation of Defendant C and D to investigate, confirm and explain the management relationship of the object of brokerage.

Therefore, the defendants are liable to compensate the plaintiffs for the above damages.
