First, prove that you are the lessee to perform the contract.
According to Article 6 of the Interpretation of the Supreme People's Court on Several Issues Concerning the Specific Application of Law in the Trial of Disputes over Urban Housing Lease Contracts, if the lessor enters into multiple lease contracts for the same house and the lessee claims to perform the contracts, the people's court shall determine the lessee who performs the contracts in the following order:
(a) has legally occupied the rental housing;
(2) Having gone through the registration formalities;
(3) The contract was established earlier.
Therefore, in the case of one room and two rents, the first time is to calm down and prepare relevant evidence to prove that you are the lessee who performs the contract.
If you have moved in and another tenant has not, then the house itself is a legal tenant.
If both parties have checked in before finding out the situation of one room and two rents, they need to prepare for registration at the Housing Authority. If they are not registered, they need to prepare their own rental contract to see who signed the contract first.
If the above evidence can't prove that you have priority, then start preparing the evidence of landlord's breach of contract.
Second, collect the evidence of the landlord's breach of contract and the details and evidence of his actual loss.
If the first method fails to obtain the rights of the lessee of the leased house, it may request to terminate the contract and compensate for the losses, which shall be handled in accordance with the relevant provisions of the contract law.
Article 97 of the Contract Law of People's Republic of China (PRC): If the contract has not been performed after dissolution, the performance shall be terminated; If it has been performed, according to the performance and the nature of the contract, the parties may demand restitution and take other remedial measures, and have the right to demand compensation for losses.
Here you need to prepare your own rental contract and another tenant's rental contract to prove the landlord's behavior of renting one room and two halls. Here, if the landlord and another tenant refuse to provide it, they can complain to the Housing Authority.
There will be a specific agreement on the landlord's liability for breach of contract in the rental contract, which can directly help us reduce losses. If the landlord's liquidated damages cannot cover your actual losses, you need to collect your actual loss list and evidence. For example, after collecting the evidence that you bear the expenses such as decoration, network, water and electricity, you can bring a lawsuit to the local court.
However, it is recommended to negotiate with the landlord first. If negotiation fails, go directly to legal procedures to safeguard their legitimate rights and interests.
Renting one room and two rooms is certainly hateful. As a lessee, you must keep an eye on the housing before renting, get a good understanding of the housing in advance, and find a reliable intermediary when necessary, which can also protect yourself to a certain extent.
