My mum passed away 12 months ago, we both lived in a council house and she had a secure tenancy, I still live at the property. I would like to succeed in the tenancy. The tenancy started in 2018 which does not allow for a family member succession, however, she previously held a secure tenancy from 1998, which I could have legally succeeded to. Due to a regeneration of the area where we lived, the council moved us to a new property and that's when the 2018 tenancy started. The council promised the new tenancy would not change (this I have in writing from one of their publications) because of the rehousing and that we would keep the same rights. The new tenancy is also a secure tenancy but it does not make mention of succession rights. Since the council had to provide us with a house with the same security of tenure as we previously enjoyed, could I defend a case in court that some rights were taken away from us when we were given the new tenancy, as they now have a right to evict me from the house and they would have not if we had not been moved to another house?
