Its a rented property with periodic tenancy agreement and tenancy agreement is silent about this. But I have been parking there from 6 years in front of my ground floor flat and these parking bays are inherently belong to this block of flat. It has recently been started enforcing and the management company issues one permit per flat without specially enrolling the registration number of the vehicle. According to signage, the permit must be displayed at all times which implies that even if you forget then will be slapped with penalty. So, is there any way to challenge it because according to people reviews they always refuse your appeal and keep on sending you bailiff notices.
