Dear Sirs,
My grandfather had built a house in 1930in Hyderabad and had died in 1960, after writing a will (Unregistered ) favouring 2 of his sons my father and my uncle, My uncle had died in 1982 and my father and my auntie(father's brother's wife) had partitioned the house (again unregisterd deed) but was signed by all the grand children. My auntie also died in 2010; My father who is still alive entered into an agreement with a builder to get it developed and accordignly asked my cousins(father's brother's children) also to be part of the development agreement. All of us have agreed in principle to give it to one developer selected by my father.Acordingly before signing the development deed with the builder on good faith he offered an alternate flat one to my father and another to my cousins until the development of property is completed. Now my own sister is not vacting the ancestral property, inorder to demolish it and give it to builder. What are the options to vacate my sister inspiite of my father offering her equal share in my grandfather' s propery. As she is threatening my father how do we tackle her, she is unmarried. Please advise.
