Can my elder brothers wife ask for property on his death

a daughter in law or grand children have rights per succession Acts applicable as long as sec 125 in Cr P C is active in law of crimes;

u all never looked after the so called properties of tour mother but that elder man did accepted by your statement that means you neglected when so what rights you alone can have on your mother's properties, as long as your elder brother is elder brother legally, even illegal born brothers to your father too have rights, after all your mother did not earn by herself but she might have got by some intestate or otherwise bestowed by her husband that is why you cannot have exclusive right over her properties please

if you are confident get settled by courts of law which your brother's widow and her children can use per se under law;

Be sensible and kind after all she worked with your brother in protecting your mothers properties and that way those properties are still there. Your brother could have sold those properties and f sold what you have to partition exclusively for you young men!

Be prudent s a mediation and conciliation concept under sec 89 of CPC 1908.

I guess you got me wrong some where. I am sensible and kind, it is just that the the sister-in-law or there family is not so kind and sensible. Just after 1 day of my elder brothers death they are asking how much money he has left, what all policy he did (which he never disclosed to us anytime), when are we selling the shop. Me and my younger brother did not entered into the business because we never wanted to fight with one business and a shop so it was our elder brother who was looking but he never even use to take good care of our mother as well. 

And his wife had always some problem with the marriage till the last day of his life, she even does not take proper care of her daughter who is just 1.10 months old, she beats her like anything. She will not even let us to take care of the child. We want to pay everything to her but what if after she get will take care of the child, she already had extra marital affair, what if after paying all the money and property she gets married once again and does not take care of the child.

Giving money and property is not the matter. The question is responsibilities, she never took any responsibilities and now she wants our money and property.
