i have a house where we live which is under my grandfather's name.My grandfather has 3 children ,1 Son(my Father-who is expired now) and his 2 daughters who are still alive.The house is still in my grandfathers name.my grandmother has also expired .there is no Will for this property. Me ,my mother live in this house only which is under my possession.My 2 aunts(his daughters) and my 3 sisters(his granddaughters) are all married and live in their own houses.My question is
1) How will this property be divided now among my 2 aunts,me ,my mother and my 3 sisters.
2) what does the Hindu undivided act/hindu succession act say in this regard.
3) can a will which is has no witnesses on it hold good.
4) As my father is no more so i ,my mother and my sisters will get only his share or the whole propertynow will be equally divided
5) As this property is still not in anyone's name as grandfather and grandmother has expired ,and lease is also not renewed --will it create problems for me and other grandchildrens
Please advise.
