Can daughter claim share in ancestral property?

I am a 52-year-old orphan woman and a patient, with no support from anyone. My father had property, including a house, cash, and jewels. Some of the property was my mother’s ancestral property. My father had stated that all assets should be equally shared. However, my brother has taken everything without giving me any share. I approached the Legal Aid services of the court, but they have not filed a case against him. It appears that bribery and influence are playing a major role. I believe I am entitled to an equal share under the applicable laws and amendments over the years (1989, 2005, 2020). My brother has also created a fake settlement in his own name. I am unable to file a case because my brother uses influence and bribes to make me run from court to court. I am in critical condition and urgently need help to get my rightful share. Can any lawyer in Chennai assist me? Please advise me at the earliest.
