First thing. Have patience.
Court will give fair chance to both of you to speak via your lawyers.
Usually HC wont interfere in interim alimony matters as it is applicable only until existence of other litigation such as divorce and as it is interim in nature. If your husband does not have job then court will order to earn and pay you money , ususally 1/3rd of his income is IA. If he hiding his job, then you need to make known to court about his job details, such details can be gotten through appointment of person called as court commisioner. He can get details of husband job, immovable property based on that, IA will be calculated.
You will be intimated to come and give your say in HC via your lawyer or in person.
Regarding ur marks cardsl give police complaint to jurisdiction police station that so and so, they get your certificates by ur inlaws.
My suggestion, with marks card and job you cannot live life. Police and court are for criminals, theives etc not for husband and wife, the moment you approach court police, half of marriage is over, try and reconcile with husband, and inlaws. Its easier to say sorry and bow head before husband and inlaws than to bow head in front of strangers. For sake of child adjust with husband and go back to him no matter what. Dont contact on phone, go talk in person, your life and your childs life are in your hands, so you only need to approach husband and do talk.
All the best.
