Case: Xiao Li rents Uncle Wang's house for a long time. One day, Uncle Wang told Xiao Li that he needed to sell the house leased by Xiao Li due to asset turnover and asked whether Xiao Li was willing to buy it. Xiao Li said that he had no money to buy it. Half a month later, Uncle Wang sold the house to Aunt Han. Aunt Han found Xiao Li and asked him to vacate the house within one month. Is aunt Han's request legal? It is illegal to say so in this case. Article 458 of the Civil Code stipulates that the use, income, liability for breach of contract, etc. of immovable or movable property shall be in accordance with the provisions of the contract; Where there is no stipulation or the stipulation is not clear in the contract, the relevant legal provisions shall apply. Article 725 of the Civil Code stipulates that if the ownership of the leased property changes during the period of the lessee's possession according to the lease contract, the validity of the lease contract shall not be affected. Xiao Li's possession of the house based on the effective lease contract belongs to the right of possession. Aunt Han has no right to request Xiao Li to vacate. (news agency)
