Employees of a Public sector undertaking formed a Housing co operative society. One of the Hindu lady employees was allotted a house.The lady did not register the property as she was bed ridden.She died without making a will. Her husband also died without making a will.Now, the property was transferred by co operative society to the six children who are the legal heir of the property and registered the property in their name through deed of conveyance by the co operative society. All the 6 children are married and want to sell the property. However, one of the children's wife is objecting to it and want share for her and her two kids born from her husband. Question: 1) Does she or her kids have any right or share in the above property?. 2) Can she or her kids can file a case in court of law for any stay order? 3) Can she or her kids file a case against the person who purchases this property, claiming share in this property?4) Can she take any other legal action against the purchaser.? I plan to purchase this property from 6 children.Thanks
