Hi, I have been living in my mum's house with my sister for 5 years and she said if I pay the mortgage, which I have done, she will leave it to me when she dies. My mum is not well and could die anymoment and last week i found in a draw a transfer of the house into my sisters name. I am worried as I have paid $160,000 in the last 5 years. Does my sister own the house under property law? Can I get my money back? Thanks.
