Harassed by sisters

Sir, we are 4 siblings two married sisters, me and my brother. We both together live in a single house of our parents the house is in the name of my mother. Recently my father has sold some properties in his village area and the total sum amount of the land is worth 60 lacs. Now my two sisters are continuosly creating problem for us, by taking advantage of our general interior domestic disputes (specifically not related to property ) , and I found out that my sisters are continously misleading my parents and telling them not to share the property money with me and my brother and the point which they are using is.... They are telling my parents that if they will give their sons equal share of money then we will not take care of them and we will abandon them and mistreat them !!WHICH IS NOT AT ALL TRUE!! ... instead we both brothers are the only one who have treated and took care of our parents when they were medically unfit...... Things are crystal clear my two sisters want all the money of our parents , and they are misleading them .... and my parents are also emotionally attached to our sisters..... If we try to raise our voice our parents threaten us to leave the house as they are the legal owner of the house... My parents have been mislead by sisters that we don't give them food and take proper care of them..... Which is not true and if needed I have the documents to proof that. Sir it is like a daily torture for us please, sir help!!!
