In a shared house under a joint tenancy. One tenant left on bad terms. We (4 remaining tenants) aren’t sure when he gave his formal notice as both he and the agency have had poor communication. Now the agency is saying we must move out by August 31 as the formal notice ended our tenancy but are unable to provide evidence of the formal notice. Can an agency kick us out if they are unable to show us the formal notice that was provided?
