Divorce and nullify of marriage

I got married 7 months ago. After marriage many things about him are revealed the first thing is I never liked him only due to my family pressure I agreed. reason was he was only bcom graduate and I am a ca inter clear. my family was of the view that they have a good property so I should say yes. After marriage I found many weird things about him he behaves like uneducated person then I cross verified many things and I came to know that he is 10th fail and achieved a tybcom degree from some village where u don't even need to clear 10th or 12th in short they cheated me. I asked him many times about his marks before but he always ignored. and the other thing is before marreige they showed their one of the property which is under dispute and they didn't even reveal it. I left that home after 2 months of marriage due to his illeterate behaviour and Daily torture and after knowing about his fraud. then we went to our samaj wher divorce is granted on stamp paper but I know we need to get divorce in family court only he is illeterate so he doesn't even know that stamp paper divorce are not even legal. I want help now can I appeat for nullity of marriage based on fraud reason plz help I can't for 1 year.
