Sir, My situation is same as below "hi sir, I am husband party.i want divorce from my wife because of below reasons: 1. wife has denied me proper sleep and food. every day quarrelled with me during dinner and at sleep .also, my wife suspect my character. fight is mainly because i am care for my parents. i need to care my parents being their only son.but, she wants me to separate. are there any law to protect the rights of old people? I have sufficient proofs in form of videos which proves that my wife want divorce and she only quarrel and not me.she also stated that she was not happy with marriage and only forced by her dad. sufficient video and audio proof available. also, video recording is there to prove she hates my parents and want them to die. I get around 60-65k after tax deduction. What is maximum compensation that can be asked by my wife's family after considering that sufficient proofs available to prove that i suffered severe mental torture from my wife and her family? I do not have recordings which can be had since i go thru daily torture and abusive langauge. I do not have a job now and am above 50.i am accused of why i do not have job though with hard work i have purchased few properties and can survive on rent. Trusting my wife i included my wife name during registration of properties though she paid some amount in one of the properties only In case of divorse will i have to give half of the properties to her though i have earned and made them honestly. Also what will be the alimony i have to pay if my monthly rental income is around 40000.
