Daughters right on mother's property

If your grand father had died intestate, and your mother does not have any siblings, then it  becomes your mother property, she has all the right to settle in anyones name, your brothers cannot contest that right.

If it is you mother's father's property devolved upon your mother, the neither you nor your brothers can claim anything during the lifetime of your mother. However, after your mother all her heirs will be equally entitled to have a share in the property.

The self-acquired property of grandfather (mother's father) shall devolve upon all his (Grandfather's) siblings equally, if he died intestate.

In this eventuality, the share of your mother (being her self-acquired property) shall be passed on to her  choice or equally amongst all of you (your borthers & sisters) if dies intestate otherwise, she may beaqueth to any or all of you.  .

Point No.1, it is your grandfather's self acquired property, upon his demise, it devolved upon your mother.  Now this property becomes your mother's own and exclusive property upon which nobody has any right, interest or share in it. Now, it depends on your mother to divide and allot the share in the property among her own siblings/children, she can allot any share to anyone or may not allot any share to a particular child or daughters or to a son or even to any of her children and she may bequeath the entire property to any trust also, she cannot be questioned or forced to act as per somebody's desire with regard to the property.  Therefore neither you nor your brothers cannot as a right claim any share in the so called grandfather's property.  This is law.

Your brothers are worng.  They are not only entittle to claim their right over the property.  Moreover right accures only after the death of mother but not during life time of mother.

I F YOUR MOTHER DIED INTESTATE IN THAT EVENT ALL  OF HER SONS AND DAUGHTERS ARE THE OWNERS JOINTLY WITH EQUAL SHARES.
