Thank you so much for your answer. I'm assuming she does have power of attorney... We are unsure as the relationship between my stepmum me and my sister's has been strained over time to say the least. We were sort of aware that the accommodation requires a deposit but we do not know how much it is, however she has said it is taken care of. She plans to buy a unit after selling the house, does that then mean then she owns that unit outright? I have not seen my dad's will but I do remember him mentioning many years ago now that he updated it to include my stepmum, me and my sisters basically dividing the value of the house between the 4 of us. Does that become null and void if the house is gone?
