I was advised to severe the tenancy only a week ago by a solicitor for my mum and dads house. I asked if that would be considered as deprivation of asset and he said no. He also advised that mum make a new will leaving her half to my brother and I. We are currently in the process of doing this. I should say this was advice from 2 different solicitors. He also added that we should remove mums half of the joint account and then continue to use it .
