There is not set or guaranteed timeframe. How long the process takes varies depending on which procedure is being used, whether the claim is defended, the court's own resources and availability, and whether or not the tenant leaves the property when they are ordered to by a court.s. 21 notices must be a minim of 2 months long whereas s.8 notices based on rent arrears are a minimum of 2 weeks.We estimate that for undefended court proceedings, a s.21 claim would result in a court order approximately 6 to 8 weeks from the date of issue of the claim. A s.8 claim typically results in a court order approximately 10 to 12 weeks from the date of issue of the claim, mainly because this process involves a court hearing.Beyond this, if the tenant fails to vacate in accordance with the court order, and a court bailiff needs to be appointed, the process of actually obtaining possession will take longer.
