My grandfather was one of three siblings who jointly owned a residence in Kolkata, where the majority of our extended family resides. Following my grandfather's marriage, he and his wife had four sons and one daughter. Subsequent to their marriages, my eldest uncle and my father, along with their respective families, relocated from the shared household. Nonetheless, my two other uncles and my father's sole sister continued to inhabit the ancestral home.
Regrettably, in recent times, my father, one of my uncles, and my aunt (father's sister) have all passed away. Presently, only my younger uncle remains in the family home. The eldest uncle, who had previously moved out with his family, has since claimed and occupied our allocated portion, taking possession of the furnishings. While they initially conveyed that I could visit and stay at the house, my attempts are thwarted as they consistently locked the premises and refused to provide access to any of the rooms.
In light of this, I am compelled to initiate legal proceedings to secure our rightful share of the property, allowing my mother and me to safeguard it with appropriate access controls. However, my uncles are proposing a complete partition of the entire property, a resolution they are well aware is unlikely to materialize during their lifetimes. Given that the property is classified as undivided Hindu property, I seek guidance on a strategy to assert my rightful portion without resorting to the protracted process of selling the entire property, which would involve numerous stakeholders and potentially span an extended period. Your suggestions in this matter would be greatly appreciated.
