I lost my job due to Covid and moved back in with my parents. My parents are retired and they are old fashioned and believe that women are inferior to men and should be treated as such which I endured every day of my life when I was a child, such as in education food clothing etc. and so I could not get a good paying job like my brother. Also, in 2005/2015, they wrote Registered Will so that all of their money goes to their son, and not to daughter. But now, due to my parents bearing my monthly expenses, my brother has threatened my parents that he will not take care of them in old age (80+) because his inheritance is getting smaller because of me. So my father is asking me to leave and he will not pay any monthly maintenance to me and my mother is asking me, again and again, to either get a job soon or commit suicide. Can I file a suit to claim maintenance from my parents under Adoptions and Family Act 1956? Also, while growing up, less money was spent on me compared to my brother because I was a girl child, from food, clothing, toys, schooling, education, purchasing bicycle/motorcycle, branded clothes for son but roadside clothes and not even a bicycle for daughter. Can I sue my parents for my poverty laden upbringing but providing excesses to my brother?
