We are two married sisters. We are living with our husbands.
Our father purchased a flat in a Coop Housiing Society in Mumbai in 1970 from his own income and funds. Our mother was a housewife and had no source of income source on her own. We have various valid documents to prove these facts in our possession.
The flat was purchased in the name of our mother for taxation purpose. Our father was a joint member. Our younger brother is living in the flat with our mother and his family. Our father expired in 1985 intestate leaving behind him no Will. In these circumstances, we assume we are also legal heirs of our father having 1/4th share in the property.
As we were informed that the brother is trying to dispose off the flat to some third person without informing us, we immediately wrote letters to the Managing Committee of the Society requesting not to transfer the flat in the name of any third person without our consent as we have legal claim in the said flat.
Soon after receiving the copies of our letter, our mother registered a Gift Deed giving 100% share of the property to her only son. We have been informed that she is entitled to dispose off the flat at her own will because she is an absolute owner of the property after our father's death,
What right do we have as legal heirs of our father's property if our mother has gifted 100% share if property to our brother? How can we establish our legal rights now? How can we proceed, please advise.
