I was promised my parent's home in Madurai and spent alot of money in fixing up the house since my father used to tell my mom that he wouldn't touch the house since it belonged to me. My mom passed away 5 years ago and my older sister moved in with my dad since she lost her house due to her son's education. Last year we found out that he has gifted the house to her with letting me or my other sister know.
Background of Property-My mom was a housewife but she sold her house in Kerla and jewels in order to help my dad through his MD degree. Now he is claiming that he earned everything and my mom had no rights to his property..
1- Does my dad have the right to do this without letting us know?
2- Is there anything that can be done at this point?
