Complain against my daughter in law

Hi sir/madam, My daughter in law is troubling me a lot from the time of her marriage, til now. She is expecting me to transfer my property to her name and she is also torturing my son nd threatening him.Once she tried to hang herself wen I was not at home only my son was there at home. she threatened him by saying u r not my husband i dont need u. If u need me then pls transfer this house to my name. She always quarrel nd go to her parents house nd she stays nearly 2 months there. They both have one boy child.She doesnt allow the child to speak with me as well as to my son...We sent he for counselling and everything was setteled but she is not interested to work as well as to do hosehold work.. She wants to lead her life luxuriously.. She wants my son to work nd buy her everything.One day she and her parents attacked my house wen my son was not at home. My daughter in law hit me nicely nd her parents also hit my relatives as well.I called my son.He immediately came nd he sent all of them to get back to there home nd said i dont need ur daughter .i wil divorce her immediately they went nd complain to the police that we are not allowing her to comehome nd we are hitting them. I need suggestion from ulawyer what is the next step we ned to go forward..But my son wants to go seperate rent house nd both of them means he nd her wife has to work nd then they has to share half of the salary to the house nd to take car of their child. I am happy if they go out nd lead their life but i dont want her to come back to my house nd torture me for m property. I also have a doubt if they go for a seperate house for rent. She definitely quarrel again nd she take all of my son moneynd leave. Please suggest me wat i must do now. Thanks, Mariya
