A residential lease signed before the authorization to convert a rental building into divided co-ownership has been granted by the Administrative Housing tribunal. In such cases, the tenant is entitled to remain in the premises and cannot be evicted (by the lessor) from his dwelling by way of repossession, unless he is an assignee of the lease and the assignment took place after the sending of the notice of intention (to convert the building into divided co-ownership) or if he becomes a tenant after the Administrative Housing Tribunal has authorized the owner of the immovable to proceed with the conversion.
