Sounds like she has grounds to sue. You could help her do so, find an attorney, etc.
If she is 'not competent' to help herself [going senile, etc], then you could file for Conservatorship or Guardianship over her, and bring the lawsuit FOR her.
If serious about hiring counsel to help in this, and if this is in SoCal courts, feel free to contact me. I�ll be happy to help fight and get the best outcome possible.
