My sister has granted a lease for life which is registered at the land registry
My sister has access to the lease to confirm its terms,
My Mother was assessed by her social worker in March that she no longer has the capacity to understand her safety and needs. That social worker also asked my Mother if I could look after her money for her ie pay her bills, cancel her direct debits etc and deal with DWP for her. DWP have made her appointee. My Mother agreed to this and is very happy with the arrangement.
We were hoping that if my Mother signed a letter obviously witnessed by independents it would be enough for the land registry to allow for the sale of her house.
Hope this helps
