The plot purchased during 1975 out of my own income . Settlement deed was registered in favour of my son during 2002 dur to affection that he will take care of me and my wife till end of our life. It was indicated in the document that I have no right to cancell or modify the document subsequently. Since I have no income my son is neglecting me and likely to be shunted out. Under this circumstances Kindly advise whether I can cancell the settlement deed and sell the property. I want to settle the 50% of proceeds to my daughter and the balance to my son.If not any other way to restore the property in order to do justice to my daughter also considering the welfare of my grand children.
