Legal analysis: If the store has not signed a lease contract and has not paid the deposit, the landlord can evict the tenant at any time. Because if a house rental contract is not signed, both parties can terminate the contract at any time. If there is no contract signed when renting a house, it is regarded as an indefinite lease contract. The legal consequence of an indefinite tenancy is that both parties can terminate the contract at any time. Therefore, not signing a contract would be detrimental to both parties. When renting a house, it is safer to sign a contract after negotiation between both parties. If there is a contract, the lessee can sublet the leased property to a third party with the consent of the lessor.

Legal basis: Article 716 of the "People's Republic of China and Civil Code" The lessee may sublet the leased property to a third party with the consent of the lessor. If the lessee subleases, the lease contract between the lessee and the lessor shall continue to be valid; if a third party causes losses to the leased property, the lessee shall compensate for the losses. If the lessee sublets without the lessor's consent, the lessor may terminate the contract.
