Documents for property transfer from a deseased parent

Dear Hema,

Before we proceed to answer your questions please clarify how did your mother inherit the house from her mother and was any share given to your mother's brother's/ children in the properties held by your grand mother at the time of her death?

How your mother got the property, whether by way gift , will  relinquish deed, or thru., partition?  

If your mother has got the property as her share by way of above said means then her brother's canniot claim any share in that property.  Only legal heirs i.e., you, your father, and your other sisters and brothers have got equal share.
