We are only the good in income in whole relatives...so they planned to get property if his brothers son do funeral.....so now they are asking to give property and they will take care of my mother for food....actually they are planning to take money and not to take care of my mother and my sister marriage....as per the indian Hindu court rights daughter have right to get whole property to take care of my mother and sister marriage or my fathers bother son will get property.....if fathers brother son gets property then they will definetly don't take care of my mother and my sister.pls give any suggestion not to get any property to them....why because that boy is minor(age-10yrs) and don't know any thing...so they don't take care of my mother .....
