On November 14, 2018, the Plaintiff, after completing the registration of preservation of ownership of the instant real estate, stored documents necessary for the registration of transfer of ownership of the instant real estate in a certified judicial scrivener office, and notified the Defendants of the scheduled cancellation date of the instant sales contract, around January 3, 2019 and January 11, 2019, and notified the Defendants that the sales contract would be rescinded at the time of the remainder payment. However, the Defendants did not pay any balance.

On January 29, 2019, the Plaintiff asserted against the Defendants that the instant sales contract was cancelled due to the Defendants’ failure to pay the remainder, and sought restitution of unjust enrichment equivalent to the delivery of the instant real estate and rent.
