Is divorce feasable for me

I have been married for 9 years , have a 7 year old daughter. My in-laws have extreme Interference in my marriage and are rather manipulative and abusive. My husband is running family business that's in my father in-laws name and earning atleast 3-4 lakhs per month. In addition they own properties worth several crores. My husband is extremely controlling financially and emotionally. He does not speak to me and has not had a physical relationship with me for over 7 years now. I have health issues which make me unable to work .. he is giving me 5-7 thousand per month , that too not on regular basis. This amount includes rs 2000/- my child's tuition fee. He refuses to go for marital counseling as all the problems I have are in my head according to him. I just need a legal perspective in this situation. Is it feasable to file for divorce and claim maintenance from my husband when he doesn't exactly have the business in his name? Will the family's assets be taken into consideration while deciding maintenance and alimony? I have very little money of my own and I am hesitant as I can't even afford to pay legal fee at this point of time.
