my sister got married 19 years ago. After 7 years of marriage my brother in law quite his job and its a downhill story since then. he sold family house, my sisters jewelry all other assets they had in this duration. Almost every six months he harasses my sister to get some money from my parents or us siblings, initially he use to ask for big amount of lakhs .. now he demands 50K -20K and harassment does not stop till he gets money. He takes money in name of starting a new business, we do not know what he does with this money as he never contributes to any of house hold expenses.
From last five years my sister is working and trying to meet ends. where ever they go he take debt from people in that locality and then force the family to flee and settle in new place. recently he tried pulling same stunt again and when my sister refused to give in he left the house saying he does not want to keep any relation with her. he left behind his ailing parent with my sister to take care of them. we also suspect he has some extra marital affair but have no proof of it. My sisters In laws have a daughter who lives in maharastra (can be forced to take care of her parents?).
My sister has a son who is in first year of college and is very disturbed with all this situation. For sake of her son she tried putting up a brave front till now. Now that it has all come in open. My sister wants to get out of this marriage but has very limited resources. Please advise how she should proceed in this matter. Thank you for your help.
