My aunt recently went in to a nursing home due to dementia and its fallen to me as her only nephew (and power of attorney) to make her house and paper work secure. Among her files was the deeds to her cottage, on which I am named as Joint owner -news to me! The house was bought about 20 yrs ago when I was 10. How is this going to pan out with inheritance tax when the time comes, I've never lived in the house fulltime except to care for my aunt when she was sick. Im sure she has a will but dont know contents
