Right of daughter on property - suggestions needed

Hi ,
does the daughter has equal rights on the property of father if will is not written? This is for my mother. My grand father passed away some months back. My grandpa has two sons and two daughters. Most of the times my mother ad her second elder brother has taken care of grand parents. Now my mothers elder brothers wife is talking as is she has taken care of them and property should go to only male children.
Now another brother who has taken care did not inform my mother or her sister but informed tenanants saying that they might have to vacate house as they are planning to sell it. My mother is kind of worried that they might take off property and keep her mother in old age home. All the 3 - both brothers wife and her sister kept bitching about my grandma. All these issues happened when they done my grand fathers death cermony in our home town. My mother is not very much interested in any property though and my dad has told me that fathers property will go only to sons.
i disagreed saying that both get equal share. I am kind of intereste in getting the amount as we dont have any property at the back , dont have a own house of our own, no constant job for my dad and a non pentioner. He will be kind of dependant on me which cannot be possible if i get married. All my mothers siblings are extremely well off with their children being settled abroad.
My grand mother is still alive and my moms brother will be taking her to get some signatures done in future. Is it possible for him to take all the property by her signature ? She is uneducated. Please pour in your inputs. I am only interested in the money because my parents dont have any and i am fed up of the dependancy issue. Her sister is the one who never took care but interested in property.

 

It is not an inherited property but it is earned by grand father.
