Some years after India’s partition Mr. A acquired a piece of land in Delhi and built ahpouse. His wife died and he had 2 sons and 1 daughter. Later A three story house was built on the land in 1980s, essentially by the money pooled in by the sons. He prepared a Will in 1997 bequeathing the floor wise ownership to his 4 sons and stating the exclusion of daughter from this property. This Will was witnessed by his son in law (the excluded party’s spouse) and one son (alive and a beneficiary in the Will). The property was then converted to a freehold ownership of Mr. A in 1999. Mr. A died in 2001, his elder son and son in law are also dead.
The younger son and legal heirs of the elder son now intend to either (a) sell the property as it is or (b) have independent ownerships as per the Will. However, they envisage complications from the daughter and her legal heirs.
Please advise the way forward to achieve the desired targets (a) or (b). Any support from daughter & her family are ruled out. Also, what happens when the daughter is no more?
