Multiple linked cases

I am in huge trouble by my husband an inlaws. I had to leave my job in 2017 for emotional blackmailing by them. Then they tried to stop my phd after having baby in Dec 2019. As I refused, they forced me out of matrimonial house. (Location was Mumbai) I am living with the kid all alone in kolkata. No financial support from husband. Rather 2 cases , custody, divorce. I also have filed DV after knowing his steps. Now custody case is in motion. DV (filed in June) summon is not yet served. Divorce has 1st hearing on 4th. I have official engagement on 4th . Have no money to hire lawyer. This non appearance will effect my case or not I don’t know. But I have no option. I know your fee is high. But still trying to get advise for the shake of my and my baby. Please dont be offended. I need help to get back to the life of dignity. I am an IIT phd in engineering. if someone can help me in court case, able to give some mental peace and mamage some financial support from my husband (earn more than 3 lacs per month) for the kid, I shall able to manage a job and then will pay all dues. Or the amount can be paid if a reasonable amount of maintenance is ordered by court. I am suffering because pf my honesty and considering others also as honest as me. So, please have faith on me. I shall not cheat anyone.
