Hi.

If it is a self acquired property of your grand father, then all the 9 children in equal shares. 

However if your grand father had inherited the property from his father(great grand father), we should then see when did the property pass in to the hands of your grand father. 

If your grand father had obtained the property by way of inheritance and prior  to 1956 , then daughters who got married prior to 1986 will not get any share. 

If your grand father had obtained property by way of inheritance and after 1956, then his daughters will get equal share along with his sons by virtue of AP Hindu succession amendment act 1986.

Hope this information is useful

Property will automatically devolved upon all 9 children equally. Nothing to do.

Partition suit will file. All have 1/9th share equally.

was it the ancestral property or the self acquired property of the grand father ?
