I have been mum's caregiver for 9 yrs now but I am a single mum with 3 small children which are too much for mum to deal with at 89 years old. My sister has no responsibility to anyone beyond herself, she is a full time teacher and owns her own house which is big. Yet she won't support or care for mum and mum will need to go into care since she cannot risk falling on a toy or the other aspects of small children. I want to sue my sister for negligence and/or not helping me with mum over the years, can I do this? I feel she owes me damages! And if I won damages from her, I would be able to afford a home that came with a separate suite for mum so she can be near us but not within the same home as us.
