What are the proofs required...

I am married since 2yrs to an army doctor who is now a major... I am myself a medical student who is preparing for pg.. My husband and in laws in this 2 yrs of marriage mentally harrassed me like anything... My in laws in these crucial years of my marriage instigated my husband to not talk to me and even come to meet me... They always threatened me with divorce...my husband did not give me financial support after marriage and always asked me to take money from my father.. I also have the msg of my father in law telling my husband not to talk to me... Creating divorce like situations... And he used to threatened me with hammer and broke things which my dad gave me.. I have already filed for maintenance n 498a.... Is that enough even I just have a screenshot of a msg of my father in law instigating my husband... I did not take other proof as I did not know that my case would go to such extent.. And all my gold ornaments are under my mother in laws custody which she is denying in legal notice...
